Abstract

A disclosed high-temperature-resistant sealant is prepared from the following raw materials in parts by weight: 6-10 parts of bamboo charcoal fiber, 4-8 parts of hollow bead, 8-14 parts of nitrile butadiene rubber, 10-20 parts of EVA thermoplastic elastomer, 6-12 parts of paraffin oil, 3-8 parts of graphene, 4-9 parts of isocyanate, 5-8 parts of aluminium hydroxide, 2-6 parts of terpene resin, 4-8 parts of gas-phase white carbon black, 7-11 parts of diaryl secondary amine, 7-14 parts of polysulfide rubber, 5-10 parts of zinc oxide, 10-20 parts of epoxy resin, 20-30 parts of acrylate emulsion, 8-16 parts of chitin, 7-9 parts of ethanol, 5-11 parts of kerosene, 5-8 parts of illite powder and 4-8 parts of attapulgite. The provided high-temperature-resistant sealant is excellent in waterproof performance and good in high-temperature resistance and flame resistance.

Description

technical field [0001] The invention relates to the technical field of fireproof materials, in particular to a high temperature resistant sealant. Background technique [0002] Sealants are mainly used for bonding various objects or filling gaps, and their functions are mainly reflected in the two aspects of bonding and sealing. Due to the rapid development of various industries, the application fields of sealants are constantly expanding. In some occasions, sealants are required not only to have the functions of bonding and sealing, but also to have functions such as fire prevention and flame retardancy. Fireproof elastic sealant is mainly used for the fireproof isolation of various openings formed when cables, air pipes, oil pipes, air pipes, etc. pass through walls and floors, and cable trays. Due to the requirements of special environments, fireproof sealants must have high performance such as radiation resistance, ozone resistance, cold resistance, aging resistance, hi...
