Description
Technical field
The present invention relates to a kind of chemical materials, relate in particular to a kind of tackiness agent that does not contain formaldehyde, also relate to its preparation method.
Background technology
The various wood furnitures of new production both at home and abroad and office furniture are owing to be extensive use of urea-formaldehyde resin adhesive at present, and 100% has formaldehyde to pollute; The car of producing, passenger vehicle, lorry compartment interior 100% have the pollution of formaldehyde and triphen.There are 1,000,000 leukaemics in the whole nation, annual newly-increased 40,000 patients, and wherein 20,000 is child patients about 7 years old, wherein 90% ill reason is relevant with house decoration for this.
The U.S., Britain, Germany, Japan and other countries have research to formaldehyde-free aqueous isocyanate wood adhesive in the world at present, mainly contain Japanese firm of a few family as what products production was used.But because the market sale price is higher, 16000-23000 unit/ton, domestic manufacturer uses seldom, uses also few in the world.Though domestic also have some manufacturer production similar products like, but because price is higher, product is more single, has promptly accomplished formaldehydeless (as core-board) at a kind of product, but other products in house decoration (as furniture etc.) formaldehyde is still arranged, cause or exist formaldehyde to pollute.Therefore, do not have fairly large application basically, can't fundamentally eliminate formaldehyde pollution.
Summary of the invention:
The purpose of this invention is to provide a kind of tackiness agent that does not contain formaldehyde and preparation method thereof.The present invention does not contain the tackiness agent of formaldehyde, owing to do not contain formaldehyde, does not have peculiar smell, Nonpoisonous, non-environmental-pollution, and the formaldehyde of tackiness agent commonly used does not pollute; With the article of its bonding various operations, bonding strength height, water-tolerant; Its price is lower, and suitable multiple material is extensive use of, thereby has overcome the deficiency of the tackiness agent existence of present use.
