Abstract
The invention discloses an improved woodenware adhesive. The improved woodenware adhesive is prepared by using the following raw materials, by weight, 2.5-3.8 parts of oxidized polypropylene ester, 1.8-3.6 parts of calcium carbonate powder, 3.5-6.5 parts of lignin, 5-10 parts of corn starch, 1.2-2.4 parts of sodium bicarbonate, 2.5-5 parts of polycarboxylic acid alcohol ammonia amide, 1.2-3.6 parts of 4-t-butyl phenol and 2.5-5 parts of acetyl trioctyl citrate. Compared with present products, the improved woodenware adhesive is a water soluble adhesive, and has the advantages of no formaldehyde, safety and environmental protection. The adhesive is grafted by a water-soluble ally monomer, realizes wood material adhesion through wood powder surface grafting and cross-linking, has a high bonding strength, and has an initial bonding strength reaching 2.2MPa. The above water soluble formaldehyde-free timber adhesive can be cured through microwave or heating, is simple to prepare, and has good storage stability, fast strengthen building and other excellent performances.
Description
Technical field
The present invention relates to a kind of woodenware glue of improvement, belong to building material field.
Background technology
Tradition sizing agent mainly contains urea-formaldehyde glue, emulsion glue etc.Urea-formaldehyde glue have low price, curing speed fast, without color, can mix very well with water, the advantage such as easy to use, widespread use in wood-based plate manufactures, but at present there is the problem that removing residue formaldehyde exceeds standard in traditional technology and the obtained urea-formaldehyde glue sheet of formula, and free formaldehyde discharges lastingly.Formaldehyde is the potential carcinogen of generally acknowledging in the world, along with the reinforcement of people's environmental consciousness, develops one of low formaldehyde or the formaldehydeless sizing agent main development direction becoming the industry.VAE emulsion glue is important water base adhesive, meets the environmental requirement of increasingly stringent, has vast potential for future development and application prospect.VAE emulsion glue is the abbreviation of vinyl acetate between to for plastic (VAc) and ethene (Ethyl-ene) monomer emulsion multipolymer, with it for base-material add viscosity increaser, thickening material, linking agent, weighting agent after make VAE emulsion sizing agent.VAE emulsion gluing has that wet stickiness is good, curing speed is very fast, shelf-stable, water tolerance good weatherability, not easily aging, aldehyde contenting amount are less than 3.8 × 10-6, can bonding multiple material, the advantage such as safe and convenient to use.But VAE emulsion glue is still containing a small amount of formaldehyde, still fail to control very well to free formaldehyde volatile matter.In addition, although VAE emulsion glue directly can be used as sizing agent, the performances such as its original viscosity, bonding strength, water tolerance, curing speed, viscosity are not ideal enough, and application is restricted.If can research and develop formaldehydeless preparation method, improved by means such as blended, crosslinked, hydrolysis, increasing stick and improved its performance, reduce costs, VAE emulsion glue will become rare environment-friendlyadhesive adhesive simultaneously.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, provides a kind of woodenware glue of improvement, does not contain
Formaldehyde, and the performance such as original viscosity, bonding strength of lower aldehyde sizing agent is all high.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a woodenware glue for improvement, is made up of the raw material of following parts by weight: its chlorinated polypropylene ester 2.5-3.8 part, calcium carbonate powders 1.8-3.6 part, xylogen 3.5-6.5 part, W-Gum 5-10 part, sodium bicarbonate 1.2-2.4 part, poly carboxylic acid alcohol glutamine 2.5-5 part, 4-tertiary butyl phenol 1.2-3.6 part and ATOC 2.5-5 part.
Optimize, the woodenware glue of above-mentioned improvement, is made up of the raw material of following parts by weight: its chlorinated polypropylene ester 3.2 parts, calcium carbonate powders 2.8 parts, 5.2 parts, xylogen, W-Gum 8 parts, 1.8 parts, sodium bicarbonate, poly carboxylic acid alcohol glutamine 3.6 parts, 4-tertiary butyl phenol 2.8 parts and ATOC 3.7 parts.
The present invention, compared with existing product, belongs to water-soluble sizing agent, not containing formaldehyde, and safety and environmental protection.Sizing agent of the present invention uses hydrophilic vinyl monomer grafting, and by the grafting on wood powder surface and can be cross-linked the gluing of wood materials, bonding strength is high, and initial adhesive strength can reach 2.2MPa.Water-soluble formaldehyde-free wood sizing agent of the present invention can microwave curing or by thermofixation, preparation method is simple, and there is excellent storage stability, intensity sets up the excellent properties such as fast.Water-soluble formaldehyde-free wood sizing agent of the present invention can be widely used in the fields such as timber is assembled, wood-based plate.Apply the glued board that this sizing agent manufactures, its initial adhesive strength can reach 1.3 ~ 2.2Mpa, and bonding strength can reach 0.45 ~ 0.85Mpa.
