Abstract
The invention relates to an adhesive for woven bamboo mat cloth and plywood, in particular to a novel adhesive for woven bamboo mat cloth and plywood, which is prepared by preparing starch hydrolysate (starch hydrolysis adhesive) by using starch as a raw material through a hydrolysis method and mixing the starch hydrolysate with urea-formaldehyde resin.
Description
The present invention relates to a kind of machine compile the summer sleeping bamboo mat patch with and glued board stick with glue agent, it particularly is raw material with starch, method with hydrolysis, after making starch hydrolyzate (starch hydrolysis adhesive), be mixed into a kind of novel machine with urea-formaldehyde resin again and compile the summer sleeping bamboo mat patch with sticking with glue agent with glued board.
Machine volume summer sleeping bamboo mat patch at present and glued board all use urea-formaldehyde resin adhesive, this product is short storage period, only 1-2 month, especially there is free formaldehyde in this product, in the hot pressing of summer sleeping bamboo mat and glued board, free formaldehyde is analysed high-volume higher in air, and the toxicity of dense pungent taste and trace is arranged, and influences the healthy of workshop workman.
Task of the present invention is that a kind of novel mixed glue will be provided, and it can improve product storage period and reduce the pollution of free formaldehyde.
Task of the present invention is finished with following method:
Be hydrolyzed with acid with native starch, become a kind of starch hydrolyzate (starch hydrolysis adhesive), in starch hydrolyzate, add an amount of Precondensed UreaFormaldehyde Resin thorough mixing then and form.
Machine of the present invention is compiled summer sleeping bamboo mat and the novel mixed glue of glued board, and storage period is more than 6 months, and can reduce and eliminate the pollution of free formaldehyde to air, improves summer sleeping bamboo mat, and plywood production workshop workman's labor condition prevents the generation of occupational illness.
The invention will be further described below in conjunction with embodiment.
With the starch of weight 50% and 50% water (starch: water=1: 1) stir into pulpous state, the hydrochloric acid that adds amount of starch 1～10% is hydrolyzed, (hydrolysis is carried out under 50～140 ℃ of temperature), reach after the requirement with sodium hydroxide and clorox neutralization becoming starch hydrolyzate, add important 10～90% urea formaldehyde resin adhesive again according to bond condition and needs, thorough mixing filters promptly.
Claims (5)
1, a kind of machine compile the summer sleeping bamboo mat patch with and the manufacture method of the tackiness agent used of glued board, it is characterized in that with starch be raw material, make again with after urea-formaldehyde resin mixes through being hydrolyzed into starch hydrolyzate (starch hydrolysis adhesive).
2, the tackiness agent of stipulating according to claim 1, it is characterized in that starch mixes with 1～10 times the water yield, add acid down 40～140 ℃ of temperature and be hydrolyzed, hydrolysis reaches after the requirement to neutralize with an amount of clorox and sodium hydroxide becomes starch hydrolyzate (starch hydrolysis adhesive).And then make behind the urea formaldehyde resin adhesive thorough mixing of adding starch hydrolyzate total amount 10～90%.
3, according to the tackiness agent of claim 1 or 2 regulations, it is characterized in that used acid accounts for starch weight 1-50%, used acid is hydrochloric acid or sulfuric acid, nitric acid, acetic acid and oxalic acid.
4, according to the tackiness agent of claim 3 regulation, it is characterized in that neutralizing agent is a clorox 0.5～10%, sodium hydroxide 0.5～10%.
5, the tackiness agent according to claim 3 regulation is characterized in that the amount of adding urea formaldehyde resin adhesive in starch hydrolyzate is 10～90%.
