Description
Technical field
The present invention relates to a kind of tackiness agent, be specifically related to kind of plant combined artificial board material tackiness agent and preparation method thereof.
Background technology
The forest resourceies scarcity of China, in order to remedy the deficiency of timber resources, the wood-based plate industry development is rapid, has therefore driven the flourish of wood adhesive industry.According to statistics, total consumption of the wood adhesive of China in 2007 is more than 300 ten thousand tons, and is ascendant trend year by year.Existing wood adhesive kind is a lot, but main use urea-formaldehyde resin adhesive and Phenol aldehyde resin on producing are because the main raw material of this class glue is a formaldehyde, therefore, in the significant period of time of production and use, can discharge free formaldehyde continuously, influence environment and user's health.Plant amylum class tackiness agent can extensively not accepted by the human consumer owing to not containing formaldehyde.As publication number is the Chinese invention patent of CN101508876, a kind of modified starch based adhesion agent for lumber and preparation method are disclosed, this tackiness agent is to be main raw material with starch and polyvinyl alcohol, make tackiness agent host by starch being carried out carry out grafting with polyvinyl alcohol after the pre-treatment such as gelatinization and oxidation, carry out modification to wherein adding aqueous SBS emulsion or melamine formaldehyde resin again, made the lower tackiness agent of free formaldehyde content.With the artificial board that this glue is produced, free formaldehyde release reaches the E0 grade standard, but the large usage quantity of the polyvinyl alcohol of this tackiness agent, cost is higher relatively, is difficult to utilization and extention.
Summary of the invention
It is lower that the technical problem to be solved in the present invention provides a kind of production cost, and main performance index such as adhesive strength, water tolerance all reach plant combined artificial board material tackiness agent of GB GB/T5849-2006 requirement and preparation method thereof.Artificial board burst size of methanal≤0.2mg/L with tackiness agent of the present invention is produced does not contain objectionable impuritiess such as benzene,toluene,xylene, phenols.
The technical solution used in the present invention is as follows:
One kind of plant combined artificial board material tackiness agent comprises host, and described host is made by the raw material of following weight parts:
Modified starch glue 30～45, methylcellulose gum 1～3, polyvinyl alcohol 3～5, urea 0.5～1, vinyl acetate-ethylene copolymerization emulsions 30～45, bentonite 4～6, Sodium hexametaphosphate 99 0.4～0.8, water 15～25, defoamer 0.08～0.2, sanitas 0.08～0.2;
Described modified starch glue is to be 15～25% emulsion by the solid content that pre-gelatinization tapioca (flour) under agitation joins furnishing in 30 ℃～45 ℃ water.
Above-mentioned plant combined artificial board material tackiness agent can be applicable to the finger plate, the production of cold pressing glue plywood, artificial jigsaw and other artificial boards; Preferably also comprise solidifying agent when being used for the more coarse mechanism plate of splicing face, described solidifying agent is a diphenylmethanediisocyanate, and when specifically using, the weight ratio of host and solidifying agent is 100: 5～15.
In the above-mentioned prescription,
Described pre-gelatinization tapioca (flour) is the commercially available prod, also can prepare voluntarily according to a conventional method.
Described defoamer is propyl carbinol or tributyl phosphate, and sanitas is isothiazolinone or Sodium Benzoate.
The ethylene content of described vinyl acetate-ethylene copolymerization emulsions is 14～18% (quality).
The preparation method of the above plant combined artificial board material tackiness agent, its step is as follows:
1) get pre-gelatinization tapioca (flour) and join under agitation that to make solid content in 30 ℃～45 ℃ water be 15～25% modified starch glue, standby;
2) get polyvinyl alcohol and place water, be warming up to 90～95 ℃, add defoamer, polyvinyl alcohol is dissolved fully, be cooled to 45～75 ℃ standby;
3) press proportional quantity, add methylcellulose gum when getting modified starch glue and being heated to 65～75 ℃, stir, add the polyvinyl alcohol water solution and the urea that are cooled to 45～75 ℃, reacted 20～40 minutes, obtain graft starch glue; Described reinforced and reaction is all under agitation carried out;
4) gained graft starch glue is cooled to 30～55 ℃, under agitation adds vinyl acetate-ethylene copolymerization emulsions, and insulation reaction 20～40 minutes adds bentonite, Sodium hexametaphosphate 99 and sanitas after being cooled to normal temperature, and the after-filtration discharging that stirs promptly gets product.
Step 2) in, described defoamer is propyl carbinol or tributyl phosphate, and sanitas is isothiazolinone or Sodium Benzoate.
In the step 4), the ethylene content of described vinyl acetate-ethylene copolymerization emulsions is 14～18% (quality).
Compared with prior art, the invention has the advantages that: by with crosslinked, the plasticising and the further polymerization of high molecular polymer vinyl acetate-ethylene, make in the modified starch glue hydrophilic radical be improved significantly, formed complete multidimensional network structure, improve the force of cohesion of glue greatly, thereby improved adhesive strength and water tolerance; In addition, add bentonite in glue, reduced the time that moisture content enters wood fibre fast, it is too fast to prevent that monolithic from crossing the glue after drying, thereby prolonged the engineering time; Moreover, produce and use in pollution-free, no Carbon emission, meet national environmental protection and low-carbon economy policy, raw material is simple and easy to, production cost is low, uses more extensively, can reach more than 12 months storage period.
