nH) matrix material and preparation method thereof.
The polyamide 66 resin fusing point is higher, have favorable rigidity, intensity, oil resistant, premium properties such as wear-resisting,, but also have poor fire in field widespread uses such as engineering plastics and fibers, shortcomings such as water-intake rate height, suction back over-all properties descend, and toughness is relatively poor under dry state and the cold condition.Along with constantly widening of polyamide 66 Application Areas, exploitation high strength, high rigidity, high heat resistance, high-dimensional stability, flame retardant resistance, low water absorption, impact, easily the processing modified product that proportion is little simultaneously is particularly important.
As engineering plastics, the main developing direction of polyamide 66 resin is that the alternative metals material is applied to make automobile component, electronics and electrical component and other high performance structures parts, development mainly is the various technology that comprise high polymer alloy and polymer composite, improve the over-all properties of material, and give the functional performance of material, thereby make polyamide material turn to the development of special grade, widen the range of application of material from general grade.
" (Fu Benxiu compiles the polyamide resin handbook as document, Shi Zupei etc. translate, Sinopec press 1994, Beijing) point out, use inorganics filled polyamide 66s such as glass fibre, carbon fiber, kaolin, talcum can improve intensity, modulus, thermotolerance and the flame retardant resistance of material.But, because the loading level of inorganics is very big, the proportion of gained matrix material is increased substantially, can not reduce the weight of goods effectively, and also variation of the surface property of material.U.S. Pat 4537929 prepares blend such as the ethylene-propylene copolymer of maleic anhydride graft and polyamide 66 the polyamide 66 mixture of high impact toughness; US4714740 proposes blend such as polymethylmethacrylate or the 3rd component tetrafluoroethylene are prepared high abrasion polyamide 66 polyamide 66 mixture.But these patented methods can only be improved the partial properties of polyamide 66.
In recent years, adopt nanometer composite technology to prepare polymer nanocomposites and becoming new polymer modification developing direction.Use this technology, only need to fill the small amounts of inorganic Nano filling, just can make the performance of material increase substantially or give its new, special function.Utilize the intercalation compounding technology layered silicate montmorillonite can be scattered in the form of nanostructure lamella and make composite nano polymer/clay material in the polymeric matrix (as CN 1206028: a kind of nanometer composite polyamide-clay material and preparation method thereof; U.S. Pat 5910523, Polyolefinnanocomposites).This nano composite material is under the less condition of inorganic fillers content, can improve intensity, rigidity, thermotolerance, barrier and the processing characteristics etc. of polymer composites, do not reduce its impelling strength, kept simultaneously the little advantage of polymer materials proportion again, be different from general organic/inorganic composite material fully, be considered to high performance composite of new generation.
Montmorillonite is a kind of clay of laminar silicate, and the thickness of its structure lamella is about 1 nanometer, and length and width between hundreds of nanometers, have very high specific surface area and very big length-to-diameter ratio tens of.Adopt the intercalation of montmorillonite to be compounded with dual mode, a kind of be with monomer in advance intercalation in the montmorillonite lamella then polymerization form polymer, be called monomer intercalation polymeric composite method; Another kind is that polymkeric substance is called direct intercalation compounding at direct intercalation under solution or the melt state in the montmorillonite lamella.Because the huge difference on mineral filler and the organic polymer matrix properties, pure montmorillonite is difficult to directly be distributed in the polymeric matrix with the nanostructure sheet form.In order to obtain nano composite material, need anticipate (being intercalation processing) to obtain the nano organic montmorillonite to montmorillonite with organic compound.But intercalation processing is to utilize the ion-exchange and the intercalation character of montmorillonite lamella, and organic molecule is introduced montmorillonite sheet interlayer, improves the affinity of lamella to polymkeric substance, and increases the spacing of lamella, thereby promotes the intercalation of monomer or polymkeric substance.
The polyamide 66 composite material that the object of the present invention is to provide a kind of nano organic montmorillonite to fill, the intensity of polyamide 66, rigidity, thermotolerance, barrier, wear resistance and processing characteristics are improved.
Another object of the present invention is to provide the preparation method of this matrix material.
Polyamide 66 composite material of the present invention, the polyamide 66 and the 1-25 part nano organic montmorillonite that contain 100 parts of parts by weight, wherein said nano organic montmorillonite are the montmorillonite mineral powder through non-ionic polyalcohol that contains amido or the processing of cation type polymer intercalator.
Polyamide 66 used in the present invention adopts the polycondensation method preparation, and molecular weight is 15000-30000.
Nano organic montmorillonite used in the present invention is the montmorillonite mineral powder through the organic molecule intercalation processing.Through behind the organic molecule intercalation, the distance of montmorillonite sheet interlayer should be greater than 1.4 nanometers, even can reach about 7.0 nanometers.The organic molecule that is used for the montmorillonite intercalation processing is non-ionic polyalcohol or the cation type polymer that contains amido, if cation type polymer, its cationic degree comprises for example neutral polyacrylamide, neutral PMAm, cationic polyacrylamide, positively charged ion PMAm, Poly Dimethyl Diallyl Ammonium Chloride, poly-diethyl diallyl ammonium chloride, epichlorohydrin/dimethylamine polycondensate etc. between 10-100%.Above-mentioned organic molecule can be prepared the nano organic montmorillonite separately or with mode and the montmorillonite effect of mixture, and promptly described intercalator is that a kind of intercalator uses separately or multiple intercalator mixes use.This nano organic montmorillonite has good affinity to polyamide 66, can disperse by the lamella with nanoscale in the polyamide 66 matrix, also is difficult for causing the degraded of polyamide 66 matrix.
Can also contain antioxidant of parts by weight 0.2-0.5 part and the lubricant of 0.2-0.5 part in the polyamide 66 composite material of the present invention.
Employed antioxidant is the antioxidant at polymeric amide in the matrix material of the present invention, and purpose is in order to be reduced in the oxidative degradation of polyamide 66 in the preparation composite material.As four (β-(3,5-di-tert-butyl-4-hydroxy phenyl) propylamine) tetramethylolmethane (commercial disignation antioxidant 1010), (3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid octadecyl ester (commercial disignation antioxidant 1076).
Employed lubricant is stearic bicine diester quadrol (commercial disignation is EBS) in the matrix material of the present invention.The purpose of adding lubricant be the surface property in order to improve polyamide 66 and to extrude and regulate that polyamide 66 adds man-hour melt body viscosity.
The preparation method of the polyamide 66 composite material that nano organic montmorillonite of the present invention is filled is: with weight part be
Polyamide 66: 100 parts
Nano organic montmorillonite: 1-25 part
Antioxidant: 0.2-0.5 part
Lubricant: after the raw material of 0.2-0.5 part thorough mixing in high mixer is even, melt extrude granulation at the common double screw extrusion press, can make the polyamide 66 composite material that the nano organic montmorillonite is filled with ordinary method.This method is easy, easy handling, thereby cost of manufacture is lower.
Compound by direct intercalation, intercalation mode that the nano organic montmorillonite further enlarges with interlamellar spacing in the polyamide 66 matrix or part and even the mode of all peeling off are disperseed, because this silicate lamella has very high specific surface area and very big length-to-diameter ratio, thereby under less content, can improve intensity, rigidity, thermotolerance, barrier, wear resistance and the processing characteristics of polyamide 66, the proportion increase that makes polyamide 66 simultaneously again is seldom.
