Summary of the invention
At above problem, it is simple to the purpose of this invention is to provide a kind of preparation technology, cohesive force, water tolerance, preservative property, plasticity is good and drying after labile starch adhesive for construction and preparation method thereof not.
A kind of starch adhesive for construction is a main raw material with starch and water, adds various additives through oxidation, gelatinization, crosslinked making, and it is characterized in that: additive comprises ammonium persulphate, styrene-butadiene emulsion, borax, polyacrylamide and 1,2-benzisothiazole-3-ketone.
A kind of preparation method of starch adhesive for construction, it is characterized in that: in reactor, add entry, add the starch and the ammonium persulphate of blunging when heating water to 60～75 ℃, after being heated to 80 ℃ while stirring, add styrene-butadiene emulsion, borax, polyacrylamide and 1 again, after the 2-benzisothiazole-3-ketone stirs.
The present invention not only preparation technology is simple, the starch adhesive for construction cohesive force of making, water tolerance, preservative property, plasticity are good, be difficult for sagging, dry back is difficult for decomposing, and it is with low cost, environmental pollution is very little, can guarantee the healthy of the relevant personnel such as employee and user, social benefit and remarkable in economical benefits.Can be used for metope and criticize ash, sticking brick and plastering etc. also can have effective adhesive to some hydrophobic materials and goods thereof.
