Abstract

The invention relates to the technical field of rubber tape production, in particular to a flame-retardant anti-corrosion insulated rubber tape. The flame-retardant anti-corrosion insulated rubber tape is composed of a modified polyvinyl chloride base film and an adhesive layer, wherein the adhesive layer is prepared from the following components in parts by weight: butadiene-acrylonitrile rubber,chloride vinegar resin, chloroprene rubber, rosin resin, ethyl acetate, graphite micro powder, dimethyl dimethoxy silicane, stearic acid, diphenyl silanediol, an anti-oxidant and an inorganic filler.The rubber tape is good in adhesion force and compactness, has good tensile strength, good peel strength, chemical corrosion resistance, mildew corrosion resistance, oxidization resistance, is fireproof and flame-retardant; and the adhesive layer can achieve the wateproof effect, so that the insulation property is better.

Description

technical field [0001] The invention belongs to the field of adhesive tape manufacturing, and in particular relates to a flame-retardant and anti-corrosion insulating adhesive tape. Background technique [0002] As we all know, my country's current demand for energy has grown rapidly with economic development. A large number of long-distance pipelines for natural gas and oil have been laid. The environmental conditions along the way are complex and changeable, and the requirements for pipelines and protection are quite high. This is for us The anti-corrosion engineering of conventional pipelines puts forward very high standards. At present, epoxy asphalt is mostly used for domestic pipeline anticorrosion. The construction and protection of asphalt are difficult to meet the requirements of engineering quality, and the uniformity and sealing performance are poor. [0003] Polyvinyl chloride can effectively resist creep damage caused by soil stress, and the aging test proves th...
