Abstract

The invention discloses an improved environment-friendly and low-toxicity wood adhesive which is prepared from the following raw materials in parts by weight: 3-8 parts of konjac glucomannan, 3-10 parts of disodium hydrogen phosphate, 6-8 parts of hydroxyethyl urea, 6-10 parts of polyvinyl alcohol, 3-8 parts of kaoline, 3-5 parts of water glass, 3-9 parts of short fibers, 4-6 parts of a stabilizing agent, 3-8 parts of zinc oxide, 6-8 parts of a polyisocyanate coupling agent, 5-10 parts of ethyl acetate, 6-11 parts of glycerol ester of rosin, 4-9 parts of pentachlorophenyl laurate, 3-6 parts of ethyl p-hydroxybenzoate, 8-13 parts of 2,4-dimethyl-6-tert-butylphenol and 3-7 parts of light calcium carbonate. The improved environment-friendly and low-toxicity wood adhesive has the benefits of very good adhesion property, relatively low toxicity, basically no influence on the environment and a human body, and long service life.

Description

A kind of environmental protection low toxicity based Wood Adhesives of improvement

Technical field

The present invention relates to a kind of environmental protection low toxicity based Wood Adhesives of improvement.

Background technology

At present, China's glued board tackiness agent used is take formaldehyde as the thermosetting resin of Material synthesis substantially, and comprise urea-formaldehyde resin, resol, melamine formaldehyde resin (being commonly called as three-aldehyde glue), wherein urea-formaldehyde resin consumption is more than 80%.The release period of formaldehyde reaches 3-15, can not vapor away completely, thus cause formaldehyde content in indoor air to exceed standard for a long time, work the mischief to the healthy of people after finishing in 1-2.Because urea-formaldehyde resin adhesive is seriously polluted, along with people are for the enhancing of environmental protection consciousness, it is a kind of little to environmental influence that people start development, can meet the sizing agent of service requirements simultaneously.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of environmental protection low toxicity based Wood Adhesives of improvement, has good cohesiveness, and simultaneously toxicity is less, on environment and human body substantially without affecting, and can life-time service.

For solving prior art problem, technical scheme provided by the invention is, a kind of environmental protection low toxicity based Wood Adhesives of improvement, and it is made up of the raw material of following parts by weight:

Rhizoma amorphophalli glucomannan 3-8 part, Sodium phosphate dibasic 3-10 part, hydroxyethyl urea 6-8 part, polyvinyl alcohol 6-10 part, kaolin 3-8 part, water glass 3-5 part, staple fibre 3-9 part, stablizer 4-6 part, zinc oxide 3-8 part, polyisocyanates coupling agent 6-8 part, ethyl acetate 5-10 part, ester gum 6-11 part, pentachlorophenyl laurate 4-9 part, ethyl p-hydroxybenzoate 3-6 part, 2,4-dimethyl-6-tert.-butyl phenol 8-13 part, light calcium carbonate 3-7 part.

The invention has the beneficial effects as follows: the environmental protection low toxicity based Wood Adhesives of improvement of the present invention, has good cohesiveness, simultaneously toxicity is less, on environment and human body substantially without affecting, and can life-time service.
