Abstract
A light hollow wall plate with conventional universal structure is made up of aluminosulfate cement, glass fibre, powdered coal ash, expansive material, building plaster and water through conventional technological steps and additional steps including adding core mould, taking it out and demoulding, and features light weight, low cost, high strength, better physical performance, and natural curing.
Description
The present invention relates to a kind of building slab and preparation method thereof, particularly a kind of Light trabs that is applicable to Highrise buildings and free modular house non-bearing wall body and preparation method thereof.
The tradition materials for wall is the sintering solid clay brick mostly, its not only with soil, ruin the field, take a large amount of soils, and consume coal, contaminate environment.For adapting to the needs of modernized Highrise buildings and free modular building construction, gradually adopt novel non-lbearing wall material to replace sintered clay brick, to alleviate the buildings deadweight, reduce construction costs.The Light trabs that emerges at present; all belong to this series products as disclosed 90101518 " light cellular partition board of silica-magnesia " of Patent Office of the People's Republic of China's communique, 93214229 " enhancing foamed cement plate ", 93244814 " refinforced cement partition plates " etc.; also having light steel keel gypsum board, gypsum perlite cored slab, cement perlite cored slab etc. in addition, all is protection land resources, energy-conserving product.Above-mentioned member all has advantage separately, all there are the certain shortcoming and the limitation of use by contrast, still not ideal enough, as commonly have that sheet material fragility is big, intensity is low, the carrying cracky, the general halogen of the easy moisture absorption, distortion, poor water resistance, the range of application that also have are subjected to certain limitation, and problems such as metal embedded part corrosion all are further improved; Patent Office of the People's Republic of China discloses a kind of " quick-hardening hih-strength cement microporous hollow light wall plate and preparation method thereof " with publication number 1122316A, though it has widened the scope of its application, but it is common stirring of other raw material of Duan Bingyu that 15-25mm is grown in processing as the inorganic fibre of strengthening intensity and the shock-resistant ability of enhancing or organic fibre, so cause stirring inhomogeneous easily, thereby influence the quality of body of wall, cause the intensity of body of wall also inhomogeneous, impact resistance is not strong, and this wallboard physique is heavier, and cost is higher relatively.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art and a kind of light hollow wall plate and preparation method thereof is provided, this wallboard physique is light, cost is low, intensity is high, shock-resistant ability is strong, and have good physicalies such as planeness is good, waterproof, fire prevention, sound insulation, insulation, its preparation technology is easy, with short production cycle, the plant factor height significantly improves work efficiency.
The object of the present invention is achieved like this: this wallboard adopts conventional hollow light wall board universal architecture, used weight percent is following raw material: aluminosulfate cement 45-55%, expanding material 10-15%, flyash 30-35%, plaster of Paris 4-7%, and the glass fibre of trace and the water that accounts for the heavy 40-55% of raw material, it is 450-560kg/m that above-mentioned raw materials mixes the microbubble slip capacity of making
3
The preparation method is as follows: take by weighing above-mentioned raw materials according to quantity, and earlier that cement, plaster of Paris and flyash mix is even, add expanding material again and carry out mix, treating to add after mix is evenly entry, to stir into unit weight be 450-560kg/m
3The microbubble slip, again this slip casting in group die, when assisting into thickness is three of design thickness/for the moment, flat surface, the auxilliary then glass fibre that equates with the wallboard design area of going up, again core rod is inserted in the mould, then add the microbubble slip again to three of design thickness/two o'clock, auxilliary more as stated above glass fibre after making firm by ramming, and then add the microbubble slip to design thickness, and make firm by ramming smoothly, can loose core in 1-1.5 hour in mould, placing under the room temperature, the demoulding in 4 hours, natural curing promptly can be made into wallboard.
The present invention has following advantage with respect to prior art:
Because adopting, the present invention has early by force, high-strength, rapid hardening, the aluminosulfate cement of good characteristics such as self hydration heat height is a consolidating material, add flyash, repaving the upper glass fiber is strongthener, add expanding material simultaneously and be mixed into the foam slip, behind the control slip capacity, be cast in the group die, utilize this cement self hydration heat, need not steam curing and promptly can be made into wallboard, so this wallboard is except that the advantage with existing various Light trabses, also effectively overcome it and be affected by the external environment, easily the moisture absorption, general halogen, distortion, poor water resistance, shortcomings such as the production cycle is long.Because the special intervening mode of glass fibre makes this wallboard have good intensity and shock-resistant ability, and wallboard physique is light, cost is lower.Wallboard characteristic of the present invention and visual appearance obviously are better than existing wallboard, its flat appearance, can follow closely, saw, bore, dig, minimizing body of wall area occupied about 50%, it is loosed core, demould time is lacked, and does not have " three wastes " in the production process and produces, and is free from environmental pollution, can also turn waste into wealth, the plant factor height, without vapor cure, with short production cycle, significantly reduce manufacturing cost, speed up capital turnover, synergy is fast, rapidly broadened application.
The present invention is further illustrated below in conjunction with implementation method
Embodiment one:
At first, take by weighing each raw material by formula ratio: aluminosulfate cement 42kg, expanded vermiculite 10.92kg, plaster of Paris 3.36kg, flyash 27.72kg, and the glass fibre that two lengths are respectively 2800 * 600 * 90mm is standby, then that aluminosulfate cement, plaster of Paris and flyash mix is even, add expanded vermiculite again and carry out mix, treat that it is 450-560kg/m that the even water that afterwards adds 34.44kg of mix stirs into unit weight
3The microbubble slip, and then this slip casting in group die, when assisting into thickness is three of design thickness/for the moment, after promptly completing bed material, flat surface, auxilliary then last layer glass fibre is inserted core rod in the mould again, then add the microbubble slip again to three of design thickness/two o'clock, material in promptly laying, after making firm by ramming, auxilliary more as stated above glass fibre, and then add the microbubble slip to design thickness, promptly lay lining, make firm by ramming smoothly, can loose core in 1-1.5 hour in mould, placing under the room temperature, the demoulding in 4 hours, natural curing promptly can be made into the wallboard of 2800 * 600 * 90mm.
