Further, described PTFE fiber layer at least comprises a PTFE silvalin, and the diameter of described PTFE silvalin is 0.01-0.05mm.
Further, described 80S alkali-free glass fiber layer at least comprises ten alkali-free 80S yarns.
A preparation method for zinc oxide industry dedusting specific products, described method: the first step, by 80S alkali-free glass fiber yarn and a PTFE yarn twisting; Second step, processes base cloth layer by first step operated products with interweaving through loom with the pure glass fibre yarn of 80S alkali-free; 3rd step, carries out compound by base cloth layer and aramid fiber layer, acrylic fiber layer; 4th step, puts into the product of the 3rd step compound in impregnating autoclave and floods, obtain product after having flooded.
Further, in described impregnating autoclave, impregnated raw material ratio is:
Polytetrafluoroethylene (PTFE) concentrates dispersion liquid 16%
Resin cloth emulsion 10%
151 coupling agents 2%
Water 72%.
The beneficial effects of the utility model are:
1, its base cloth of the utility model adopts 80S alkali-free glass fiber yarn, is interwoven through loom by 80S alkali-free glass fiber yarn and a PTFE yarn twisting and the pure glass fibre yarn of 80S alkali-free, and its longitude and latitude is powerful improves 12% than just, rotproofness raising 15%; And aramid fiber, its yarn count of special acrylic fiber are thin, be 2.2-2.7D chemical fibre, can reach 230 DEG C with glass composite for base fabric heatproof, soft abrasion-resistant folding, yarn count pinhole is little, easy bonding is not peeled off, this product is again through impregnation process, and its property indices can improve 22%, and this product is the middle-grade filtrate that domestic bulk raw material is made, its cost performance is high, and service life generally grows 1 year than other products.
