Abstract
The present invention open a kind of novel non-formaldehyde, benzene-free and environment-friendly glue.Count by weight, this glue is by including that following raw material prepares: polyether Glycols 70～100 parts, 2,6 toluene di-isocyanate(TDI)s 30～50 parts, chain extender 10～20 parts, acetone 50～80 parts, vinyl acetate acrylic acid ester copolymer emulsion 20～30 parts, thickening agent 2～4 parts, firming agent 1～3 parts, zinc oxide 1～3 parts, 100 parts of water.Compared with existing glue, the glue of the present invention does not contains formaldehyde and benzene, is a kind of environment-friendly water-based glue, and has higher adhesion strength.
Description
Technical field
The invention belongs to adhesive field, be specifically related to a kind of novel non-formaldehyde, benzene-free and environment-friendly glue.
Background technology
Because timber day lacks, wood-based plate is used to replace many conventional use of sawn timber, and its yield increases sharply.With sawn timber phase
Ratio, the advantage of wood-based plate is: breadth is big, structural good, easy construction；Dilation rate is low, dimensionally stable, and material is equal compared with sawn timber
Even, it is unlikely to deform cracking；Veneer and various particle as raw material of artifical plate are prone to dipping, thus can make various functional processing
(such as fire-retardant, anticorrosion, nonshrink, wear-resisting etc.)；Thickness level and the density level suitability of wider range are strong；Brake forming performance compares sawn timber
Good.
Wood-based plate is with timber or other non-wood plants as raw material, is separated into various unit material through certain machining
After, stick with glue agent gluing and form.And the adhesive major part being currently used for wood-based plate is containing formaldehyde products, use this kind of gluing
Agent easily causes indoor formaldehyde pollution, is unfavorable for health.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of novel non-formaldehyde, benzene-free and environment-friendly glue
Water.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
Novel non-formaldehyde, benzene-free and environment-friendly glue, count by weight, by including that following raw material prepares:
Polyether Glycols 70～100 parts, 2,6-toluene di-isocyanate(TDI) 30～50 parts, chain extender 10～20 parts, acetone 50～80
Part, vinyl acetate-acrylic copolymer emulsion 20～30 parts, thickening agent 2～4 parts, firming agent 1～3 parts, zinc oxide 1～3 parts,
100 parts of water.
Preferably, described chain extender is ethylenediamine base ethyl sulfonic acid sodium and/or dimethylolpropionic acid.
Preferably, described firming agent is vinyl triamine or m-xylene diamine.
The preparation method of above-mentioned glue, comprises the steps step:
(1) by polyether Glycols, 2,6-toluene di-isocyanate(TDI), chain extender and acetone add in reactor, are heated with stirring to 80
～90 DEG C, insulation reaction 1～3 hours, cooling, regulate pH to 7；
(2) under agitation, in the system of step (1) add vinyl acetate-acrylic copolymer emulsion, firming agent, zinc oxide,
Thickening agent and water, be uniformly mixed so as to obtain described glue.
The novel non-formaldehyde of the present invention, benzene-free and environment-friendly glue instead of traditional use containing aldehyde glue completely, formaldehydeless release,
It is adapted to the processing technique of particieboard, there is adhesive strength and the nail-holding ability of excellence, and extra-high frost resistance (0 degree to 5 degree Celsius
Viscosity is almost unchanged, does not glue press).
Detailed description of the invention
