Abstract

A wood adhesive is prepared from the following raw materials in parts by weight: 2-6 parts of sodium cinnamate, 5-8 parts of cetyl trimethyl ammonium bromide, 4-6 parts of lithium silicate, 9-16 parts of bisphenol A epoxy resin, 8-13 parts of polyvinyl acetate, 5-8 parts of butyronitrile emulsion, 3-9 parts of dicyandiamide, 5-8 parts of stearic acid, 3-5 parts of tackifier, 7-9 parts of ethylene-ethyl acrylate copolymer, 8-14 parts of sodium hydrogen sulfite, 3-6 parts of fumaric acid, 1-5 parts of sebacic acid, 5-10 parts of 2,3,6-trimethylphenol, 3-8 parts of methyl parahydroxybenzoate and 3-6 parts of isobutanol. The wood adhesive has the benefits that the wood adhesive has a good binding property, and low pollution to an environmental at the same time, and can be used for a long term.

Description

A kind of based Wood Adhesives

Technical field

The present invention relates to a kind of based Wood Adhesives.

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 based Wood Adhesives, has good cohesiveness, simultaneously little for the pollution of environment, can life-time service.

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

Sodium.beta.-phenylacrylate 2-6 part, cetyl trimethylammonium bromide 5-8 part, lithium silicate 4-6 part, bisphenol A epoxide resin 9-16 part, polyvinyl acetate (PVA) 8-13 part, butyronitrile emulsion 5-8 part, Dyhard RU 100 3-9 part, stearic acid 5-8 part, tackifier 3-5 part, ethylene-ethyl acrylate copolymer 7-9 part, sodium bisulfite 8-14 part, FUMARIC ACID TECH GRADE 3-6 part, sebacic acid 1-5 part, 2,3,6-pseudocuminol 5-10 part, methyl p-hydroxybenzoate 3-8 part, isopropylcarbinol 3-6 part.

The invention has the beneficial effects as follows: based Wood Adhesives of the present invention, there is good cohesiveness, simultaneously little for the pollution of environment, can life-time service.
