Abstract

The invention discloses a multilayer composite adhesive tape preventing chemicals from penetrating and a preparation method thereof. The multilayer composite adhesive tape is prepared by coating aramid fiber base cloth with multiple rubber, concretely, one surface of the base cloth is coated with a fluorubber layer, and the other surface of the base cloth and the surface of the fluorubber layer are both coated with a chloroprene rubber layer. The preparation technology of the multilayer composite adhesive tape comprises preparing base cloth, coating one surface of the base cloth with the fluorubber layer, performing semi-sulfuration, coating the two surfaces of the coated base cloth with the chloroprene rubber layer, performing complete sulfuration, and obtaining the finished product adhesive tape. The multilayer composite adhesive tape employs aramid fiber fabric resistant to both acids and alkalis, possesses strong physical mechanical performances and is better than a nylon material. The multilayer composite adhesive tape has relatively strong acid and alkali resistance and chemical toxic agent resistance, and has the protection time up to 4 h. The multilayer composite adhesive tape has relatively good flame retardation performance, and can work at a high temperature. The multilayer composite adhesive tape employs chloroprene rubber and fluorubber as coating materials, is low in cost and superior in antitoxin performance.

Description

technical field [0001] The invention relates to the technical field of protective equipment, in particular to a chemical permeation-resistant multilayer composite adhesive tape and a preparation method thereof. Background technique [0002] Multi-layer composite tape is an effective protective material for high-risk chemicals, military poisons that endanger life immediately, and radioactive pollution, and protects personnel from poisonous and harmful chemical industrial products, organic solvents, and strong corrosive substances. [0003] At present, multi-layer composite materials in the world are mostly composed of 3-5 layers of materials, with a thickness of 0.3mm-0.5mm and a layer thickness of about tens of microns. [0004] At present, the tapes used in skin protection equipment in the domestic market are all coated or calendered with a single rubber, and the reinforcing material is mainly nylon. First, the protection spectrum is not wide, and only a limited number of s...
