Abstract
The invention discloses an improved plywood adhesive. The adhesive is prepared from the following raw materials in parts by weight: 2.5-4 parts of talcum powder, 4.5-8 parts of high molecular weight thermoplastic resin, 1.5-2.7 parts of branched alcohol ethoxylates, 2.5-6 parts of starch, 2.3-4.2 parts of polyether polyol, 0.3-1.2 parts of propyl starch ether, 2-3.5 parts of sodium metaborate and 0.5-0.9 part of modified tree ash. The improved plywood adhesive has the beneficial effects that compared with existing adhesives, the adhesive can be implemented on conventional adhesive production equipment, without extra processing equipment; a method has the advantages of simple preparation process, mild reaction conditions and high process stability; as cheap and renewable starch is adopted as the main raw material, the adhesive does not release toxic and harmful gases and has good environmental harmonization; relative to common white latex, the adhesive has lower content of total volatile organic compounds and better environment-friendliness.
Description
Technical field
The present invention relates to a kind of glued board adhesive of improvement, belong to building material field.
Background technology
Starch adhesive, as the one of natural adhesive, has the advantages such as quality is light, corrosion-free, pollution-free, raw material is easy to get, cheap, easy to use, is widely used in the bonding of paper, cotton fabric, trade mark etc.But the shortcomings such as bonding strength is lower, wet is easily gone mouldy that starch adhesive exists, limit the application in timber-work gummed.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provides a kind of glued board adhesive of improvement, and bonding strength is high, wet is not easily gone mouldy, advantage of lower cost, environmental protection.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of glued board adhesive of improvement,
Be made up of the raw material of following parts by weight: talcum powder 2.5-4 part, high-molecular-weight thermoplastic resin 4.5-8 part, branched-chain alcoho Soxylat A 25-7 1.5-2.7 part, starch 2.5-6 part, polyether glycol 2.3-4.2 part, propyl group starch ethers 0.3-1.2 part, sodium metaborate 2-3.5 part and modification tree ash 0.5-0.9 part.
Optimize, the glued board adhesive of above-mentioned improvement, be made up of the raw material of following parts by weight:
Talcum powder 3.2 parts, high-molecular-weight thermoplastic resin 5.2 parts, branched-chain alcoho Soxylat A 25-7 2.4 parts, starch 5.2 parts, polyether glycol 3.3 parts, propyl group starch ethers 0.7 part, sodium metaborate 2.4 parts and modification tree ash 0.6 part.
The present invention is compared with existing tackiness agent, and the present invention can implement on conventional adhesive agent production unit, does not need additionally to drop into processing units; The inventive method preparation technology is simple, and reaction conditions is gentle, and technology stability is high; The main raw material adopted is cheap and reproducible starch, does not discharge toxic and harmful, has good environment compatibility; This tackiness agent is relative to common white latex, and total volatile organism is lower, and environmental-protecting performance is more excellent.
