| titleOfInvention | A kind of non-ionic starch based adhesive and preparation method thereof |
| abstract | The present invention provides a kind of non-ionic starch based adhesive and preparation method thereof, and the preparation method successively includes pre-treatment step, hydroxypropyl etherified step, crosslinking treatment step, wherein hydroxypropyl etherified step and the sequence of crosslinking treatment step can exchange；The pre-treatment step includes that starch is deployed into starch milk with alcohol；The hydroxypropyl etherified step includes that alkaline reagent and propylene oxide are added into the product of previous step, is heated to 50-80 DEG C of reaction 6-12h；The crosslinking treatment step includes that crosslinking agent and modifying agent are added into the product of previous step, and the pH value for controlling reaction system is 10-11, reacts 2-6h at 40-70 DEG C of temperature；The modifying agent is at least one of polyvinyl alcohol, polyvinylpyrrolidone, polyacrylamide.Non-ionic starch based adhesive provided by the invention can be applied in the putty or mortar of a variety of base-materials such as cement, gypsum, grey calcium, have good cold water-soluble, higher viscosity and acid and alkali-resistance, salt stability. |
