(4) according to compound: the ratio of deionized water=1: 3, in reactor, add deionized water, and to its heating; When water temperature rises to 65～75 ℃, drop into anti-stick solution A and anti-stick solution B, when evenly stirring, continue its heating; When temperature rose to 80～90 ℃, constant temperature kept 3～5 hours;
(5) when continuing stirring, in 1.8～2.4 hours, above-mentioned compound is slowly splashed into;
(6) temperature is risen to 85～92 ℃, and constant temperature keeps allowing it naturally cool to 30～40 ℃ after 1～2 hour;
(7) material in the reactor is poured out, and elimination moisture wherein, the particulate state work in-process made;
(8) with whizzer the particulate state work in-process are cleaned, and slough wherein moisture;
(9) be that 50～60 ℃ baking oven was to the work in-process drying treatment of sloughing moisture 15～20 hours with temperature;
(10) with 30 purpose sieves, the work in-process that drying was handled sieve, and make macromolecule resin of the present invention.
Adopt such scheme, have the following advantages:
1. owing in the macromolecule resin raw material of the present invention, do not contain dimethylbenzene, nontoxic, harmless to HUMAN HEALTH;
Since macromolecule resin raw material of the present invention in do not contain dimethylbenzene, and with deionized water, edible Gelatinum oxhide and food starch as suspension, can reduce production costs greatly;
3. owing to do not contain dimethylbenzene in the macromolecule resin raw material of the present invention, the gas in the production process in the reactor is water vapor, can not set off an explosion, and is as safe as a house.
4. owing to adopt edible Gelatinum oxhide and food starch as binding agent in the macromolecule resin of the present invention, making the polymeric product is particle, needn't pulverize, and has avoided because of pulverizing the mechanicalness noise that produces and to the pollution of environment.
