Abstract
The present invention relates to a composite modified starch adhesive, 108 adhesive and its prepn. method. Said adhesive is made up by using cornstarch as basic raw material and adding sodium hydroxide, monochloro-acetic acid, urea, sodium phosphate, acrylonitrile, sodium hypochlorite or hydrogen peroxide, sodium hydrogen sulfite and water. Said invented adhesive possesses stable adhesiveness, strong cohesive force, strong mold resistance and alkali-resisting property, good compatibility with other water soluble adhesive and good film-forming property, etc., so that its application range is extensive.
Description
The present invention relates to chemical glue stick class
Present commercially available Chemicals tackiness agent 107 glue are main material production with the polyvinyl alcohol, and polyvinyl alcohol is the product that Vinyl Acetate Copolymer is produced through the alcohol alcoholysis.According to the chemical industry market conditions, the difference of the world wide production of polyvinyl alcohol and demand is very big at present, and imbalance between supply and demand is difficult to relax, thereby causes the big bulge in price of polyvinyl alcohol, and the novel glue kind of therefore seeking alternative 107 glue is extremely urgent.The present invention develops a kind of composite modified starch gum-108 gum and preparation method thereof according to the problem of present existence.
The object of the invention is, a kind of composite modified starch gum-108 gum and preparation method thereof of development mainly is to be basic raw material with the W-Gum, adds sodium hydroxide, Monochloro Acetic Acid, urea, sodium phosphate salt, propylene are fine, clorox or hydrogen peroxide, sodium bisulfite, water are made 108 glue, this glue has that viscosity is stable, and cohesive force is strong, anti-ly goes mouldy, the intermiscibility of anti-highly basic and other water-soluble glue is good, clear wash rice is transparent, freeze proof molten, good film-forming property has extensive use.
Task of the present invention is to select based on carboxymethyl etherification starch, compound cyanoethyl starch ether, the hypochlorous acid oxidization technology in back step is carried out under high pH value, forms hydroxyl, guarantee the stable and minimum retrogradation of product and best transparency, make colloid have very strong alkali resistant ability.
Carboxymethyl starch ether has sharpness preferably, and strong alkali resistant ability is good with the intermiscibility of multiple other water-soluble sizing material, extremely user's favor.But the high-dissolvability of its response derivative, need just can make the product of certain substitution value in non-aqueous media or pure water blending agent when common process is made, so manufacturing cost is higher, and its viscosity is to salt ten minutes inspiration simultaneously.
The cyanoethyl starch ether of low degree of substitution is as slurry and paint adhesion agent, have good performance, the cyano group of product can suppress bacterium and mold activity, but the viscosity of cyanoethyl starch is too high, be difficult to provide and use the required concentration that enough contains admittedly, simultaneously its non-transparency also difficulty the user is accepted.
This law has been concentrated the advantage of two kinds of starch etherss, and complementary the two deficiency has adopted unified reaction conditions, has overcome viscosity and the contradiction that contains concentration admittedly, can not have under the dipping salt existence condition, and full water medium reaction production greatly reduces cost.
A kind of composite modified starch gum-108 gum of the present invention and preparation method thereof, it be by in W-Gum, sodium hydroxide (industrial solid caustic soda), Monochloro Acetic Acid (industry), urea (chemical fertilizer level), the sodium phosphate salt (sodium orthophosphate, Trisodium trimetaphosphate, trisodium phosphate, tripoly phosphate sodium STPP) any one, clorox or hydrogen peroxide, sodium bisulfite, tap water are formed its each component content (is radix unit's kilogram with one ton of product):
