Abstract

A novel resin sealant is prepared from the following raw materials in parts by weight: 20-40 parts of epoxy resin, 30-50 parts of cis-1,4-polybutadiene rubber, 25-35 parts of thermoplastic synthetic resin, 3-8 parts of diatomite, 15-20 parts of polyisobutylene, 4-8 parts of xylene solution of raw rubber, 8-14 parts of xylene, 6-10 parts of ebonite, 9-18 parts of dibutyl phthalate, 11-16 parts of asbestos powder, 10-15 parts of nanometer calcium carbonate, 7-14 parts of m-phenylenediamine, 3-6 parts of barium sulfate, 11-17 parts of rutile titanium dioxide and 6-12 parts of a phosphate fire retardant. The novel resin sealant is good in sealing property, resistant to water seepage, airtight, good in weatherability, good in low-temperature crack resistance, excellent in heat-insulation shock-proof performances, beneficial for construction and installation, and good in fireproof effect.

Description

technical field [0001] The invention relates to the technical field of building fireproof materials, in particular to a novel resin 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. In construction engineering, the sealing of various concrete assembly structure joints is very important. Common cement paste joints are easier to crack. The joint adhesives currently available in the market are either poor in sealing performance, or have poor low temperature crack resistance or poor heat insulation and shock resistance.
