(2) aluminium dihydrogen phosphate is joined in 3-4 times of water, add calcined gypsum powder, butyl methacrylate, at 80-90 DEG C, be heated to water do, obtain modified landplaster;

(3) by carbomer thermoplastic, add modified landplaster, hydroxy silicon oil, polyoxyethylene oleic acid ester is added after stirring, send in emulsifying agent, low speed emulsification 10-20 minute, adds epoxidation xylogen, in the oil bath pan of 100-120 DEG C, be incubated 30-40 minute, discharging cools, and obtains lignin resin binding agent;

(4) asphalt heating is melted, mix with sodium metaborate, exsiccated ammonium alum, dehydration, adjustment temperature is 190-230 DEG C, adds lignin resin binding agent, insulated and stirred 20-30 minute, add each raw material of residue, by colloidal mill grinding fully, obtain modifying asphalt batch mixing;

(5) above-mentioned modifying asphalt batch mixing is delivered to shaping oiling groove, tire base through carrying out application, then controls suitable thickness as required, overlay film, cooling forming from forming tank, and described tire base is polyester blank.

Advantage of the present invention is:

Alkali lignin is carried out epoxidation process by the present invention, lignin molecule degree of crosslinking increases, join in resin system, effectively can improve the insulativity of finished product, mechanical property, thermostability and bonding effect, the terra alba wherein added has good hardness, Nai Gaore and flame retardant effect.
