Abstract

The invention relates to a tape production technique, and particularly to a self-cleaning coated tape, which solves the technical problem that during tape production in the prior art, talcum powder on a tape surface and surface rubber are vulcanized and fixed together, and the talcum powder cannot be removed effectively, so that the tape surface is not smooth enough. The self-cleaning coated tape is produced in the following steps: chlorinated butyl rubber and EPDM rubber are put in an open mill for mixing, then antioxidant D and stearic acid are added into the mixture for mixing, then zinc oxide accelerant DM, accelerant M and sulfur are added for mixing, and then accelerant TT is added for mixing; mixed rubber material is warmed in the open mill and prepared into rubber strips; the rubber strips and 120# gas are added into a stirring tank for stirring to prepare rubber paste; during the rubber coating process, the rubber paste is spread to coat the upper surface of a nylon cloth evenly, the coated nylon cloth is then vulcanized, and the self-cleaning coated tape is obtained after the vulcanization. The tape produced has a good self-cleaning effect and a tidy and smooth surface, and thus can be applied to sealed packaging of medical products, precision instruments, meters and electrical appliances.

Description

technical field [0001] The invention relates to a production process of an adhesive cloth, in particular to a self-cleaning coated adhesive cloth. Background technique [0002] The adhesive tape is manufactured by the coating process, and the adhesive tape must be isolated with talcum powder during the curling process to prevent adhesion between the adhesive tape and the film. [0003] During the vulcanization process of the adhesive tape, the talcum powder on the surface and the surface adhesive are vulcanized and shaped together, adhering to the surface of the adhesive layer, and cannot be effectively removed by washing, which seriously affects the smoothness of the surface of the adhesive tape, and the appearance quality is poor. It is severely restricted in the sealed packaging and use of medical products, precision instruments, meters, and electronic equipment. Therefore need a kind of adhesive plaster that can effectively eliminate the influence of talcum powder and s...
