Abstract

The composite flame retardant insulating waterproof sealing adhesive tape includes outer layer A and inner layer B rolled and compounded together. The outer layer A consists of elastic flame retardant insulating glue EPDM4045, CPE, stabilizer, reinforcing agent, flame retardant, antiageing agent, antioxidant and promoter; and the inner layer B consists of adhesive insulating waterproof polyisobutylene, butyl rubber, adhesive terpene resin, carbon black, light calcium carbonate and stearic acid. The outer layer materials are mixed in an open stirrer and the mixture is rolled and cut to form tape; the inner layer materials are mixed, cut into strip and extruded into sheet; and the tape and the sheet are rolled and compounded to form the composite flame retardant insulating waterproof sealing adhesive tape. The adhesive tape may be used for flame retardant insulating waterproof sealing of electric joint for no-fire condition.

Description

technical field [0001] The invention belongs to the technical field of insulating sealing tape and its preparation, and in particular relates to a composite flame-retardant insulating and waterproof sealing tape and a preparation method thereof. Background technique [0002] At present, strips made of heat-shrinkable materials are mostly used for insulation treatment of various types of wire and cable joints. Based on the characteristics of heat-shrinkable materials, it is necessary to use open flame heating when applying strips made of heat-shrinkable materials. However, in some special occasions, open flame operations are not allowed: such as coal mines, oil fields, chemical industry and other places where fire is absolutely prohibited; the materials used in these places require both insulation and must be flame-retardant and waterproof. The insulating sealing tape made of heat-shrinkable material does not have the function of meeting the above-mentioned requirements at t...
