The high-efficiency, low-toxicity and environment-friendly adhesive provided by the invention has the beneficial effects that the high-efficiency, low-toxicity and environment-friendly adhesive provided by the invention is low in toxicity and harmless to a human body and an environment; and simultaneously has great adhesion and can meet using requirements.

Description

A kind of high-efficiency low-toxicity environment-protective adhesive

Technical field

The present invention relates to a kind of high-efficiency low-toxicity environment-protective adhesive.

Background technology

At present, the tackiness agent of China is mainly main production raw material with formaldehyde, i.e. urea-formaldehyde resin adhesive, Phenol aldehyde resin and melamine-formaldehyde resin adhesive, its output account for that whole wood-based panel industry sticks with glue agent more than 90%, wherein, urea-formaldehyde resin adhesive due to low cost of manufacture, raw material be easy to get, bonding strength is high, color and luster close to plurality of advantages such as timber, and is subject to the favor of most of artificial board enterprise.But existing sizing agent is very large on the impact of environment, the injury of the formaldehyde simultaneously discharged to human body is larger, people suck for a long time and may cause disease, cause irremediable loss, the one that the sizing agent therefore finding a kind of low toxic and environment-friendly has become people in the urgent need to.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provide a kind of high-efficiency low-toxicity environment-protective adhesive, toxicity is little, to human body and environmentally friendly; There is good cohesiveness simultaneously, can service requirements be met.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of high-efficiency low-toxicity environment-protective adhesive, is made up of the raw material of following parts by weight:

Synthetic polyisoprene 8-15 part, epoxy resin 8-14 part, calcium oxide 2-7 part, trolamine 4-10 part, sodium hydroxide 2-6 part, guanidine acclerators 1-3 part, coumarone 4-8 part, precipitated silica 5-9 part, starch 2-7 part, antiager 3-5 part, silicon powder 3-9 part, nano aluminium oxide 4-8 part, nonyl phenol 1-5 part, toughner 1-4 part, thixotropic agent 1-3 part.

The invention has the beneficial effects as follows, high-efficiency low-toxicity environment-protective adhesive of the present invention, toxicity is little, to human body and environmentally friendly; There is good cohesiveness simultaneously, can service requirements be met.
