The invention discloses an OCA optical cement die cutting technology. The OCA optical cement die cutting technology comprises the following steps that die cutting operation is conducted in a thousand-level dust-free room of 80-90 % humidity; after a cutting knife is dedusted, the cutting knife cuts raw materials into small rolls to be hung on a material frame; an upper layer light release film self-contained by OCA optical cement is torn, and an OCA layer is exposed; after anti-sticking processing is conducted on a rolling cutter, the rolling cutter cuts to the two sides of the OCA layer, and a reserved part is formed between a cutting line and the edge of the rolling cutter; after a mylar layer is pasted on the reserved part, and the reserved part and the mylar layer are torn together; an anti-static film is attached to the surface of the OCA layer through a rubber covered roller, and rubber covered roller foam is circumferentially attached to the two sides of the rubber covered roller; the anti-static film is cut off by a punching cutter, and the outer frame edge of a product is greater than the edge of the OCA layer; and cutting is conducted every time the punching cutter rotates one revolution, and neatly-collecting-stacking is conducted. According to the OCA optical cement die cutting technology, the effects that the product has no cement pulling and cement overflowing are achieved.

The invention discloses a cold-resistance flame-retardant anti-static polyvinyl chloride sheathing material for coal mine cable; the sheathing material is characterized by consisting of the following raw materials: polyvinyl chloride resin SG3, tri(2-chloroethyl) phosphate, an anti-static agent, dioctyl sebacate, dioctyl phthalate, tricresyl phosphate, antimonous oxide, zinc borate, tribasic lead sulfate, bibasic lead sulfate, light calcium carbonate, bisphenol A, 2-mercapto benzimidazole, vinyl tri(beta-methoxyl ethyoxyl) silane, accelerant TMTD and modified asbestos powder; the polyvinyl chloride sheathing cable material provided by the invention has the following characteristics of being low in surface resistance value and high in anti-static property; by adopting the compound high-concentration anti-static agent consisting of TCEP (trichloroethyl phosphate), quaternary ammonium salt cationic surface active agent and nonionic surface active agent, the excellent anti-static synergistic effect can be brought; the surface resistance value of the sheathing material is no higher than 108ohms, and thus the sheathing material has excellent anti-static property.

The invention discloses an anti-static ceramic floor and a preparation method thereof. The anti-static ceramic floor comprises a body of the ceramic floor, a surface layer of the ceramic floor is baked with a mixed layer of glaze and conductive powder, the conductive powder accounts for 20 to 40 percent of the material weight of the mixed layer, wherein the conductive powder comprises the following compositions in weight percentage: 55 to 90 percent of Sn, 5 to 25 percent of Zn, and 5 to 25 percent of Ti. The preparation method comprises the following steps: the glaze is produced first, and then the conductive powder is added according to the mixing proportion of the glaze and the conductive powder to mix and stir evenly; after a molding process of the ceramic floor is finished, a mixed material of the glaze and the conductive powder is coated on the surface layer of the ceramic floor according to the preset printing proposal; the baking and the separation to finished products are performed to obtain the qualified finished products.

An antistatic ceramic tile for floor or wall is prepared through preparing ceramic blank, preparing antistatic enamel from enamel and semiconductor oxide chosen from SnO2, TiO2 and ZnO through proportional mixing, coating enamel transition layer on the ceramic blank, drying, coating antistatic enamel, drying, coating antistatic enamel on its peripheral surface, and calcining.

The present invention relates to a kind of antistatic rubber plate (such as table mat, ground mat) and production method thereof, this antistatic rubber plate comprises antistatic layer and static conduction layer; This antistatic rubber plate is prepared by a, antistatic layer film ; b, the preparation of the static conductive layer film; c, prepared by the vulcanization step.
