Broken, stirring and dissolving in pi-allyl epoxidized polyether is then added into, under conditions of 28-32 DEG C, makes which expanded standby；
（2）Nanoflakes and cobalt hydroxide, distearyl acyl-oxygen isopropoxy plumbic acid ester and Fischer-Tropsch wax is added in above-mentioned puffing material, and stirring is anti-
Answer 25-30 minutes；
（3）Zinc naphthenate and polydimethylsiloxane are added in above-mentioned compound, importing are stirred when having bubble to produce through pre-
In the mould of heat, baking oven is put into, solidifies 1.5-2 hours under conditions of 40-50 DEG C, obtain final product.
As further improvement of these options, the step（2）The temperature of middle stirring reaction is 32-36 DEG C.
The present invention has advantages below compared to existing technology：In the present invention, nitrification shitosan and fir bark are in corresponding conditionses
Lower combination IPN aggregates into new network structure so as to good mechanical strength and elasticity, while raw material is more environmentally-friendly making
With rear easy degraded, waste entrainment is reduced；There is stronger fatigue performance, wearability and oil resistivity, use time is long, production
Low cost.
