Abstract

A disclosed long-acting environment-friendly sealant is prepared from the following raw materials in parts by weight: 30-40 parts of cis-1,4-polybutadiene rubber, 4-7 parts of sodium hydroxide, 15-20 parts of polyisobutylene, 4-8 parts of organic bentonite, 6-10 parts of ebonite, 13-16 parts of nanometer calcium carbonate, 2-5 parts of phenolic resins, 3-9 parts of luting resin, 3-9 parts of polyvinyl chloride-polyvinylidene emulsion, 30-40 parts of thermoplastic synthetic resin, 4-8 parts of aluminium hydroxide, 10-20 parts of rutile titanium dioxide, 5-10 parts of portland cement, 5-15 parts of a phosphate flame retardant, 5-10 parts of diatomite and 50-80 parts of water. The provided long-acting environment-friendly sealant is low in production cost, good in fireproof performance, good in waterproof performance, smooth in surface and strong in adaptability.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a long-acting and environment-friendly sealant. Background technique [0002] With the rapid development of urban and rural construction in our country, people have higher requirements on the living environment and quality. At present, the sealants used in construction generally contain organic solvents. Some sealants are buried in buildings and other supplies when they are used, and cannot evaporate quickly. Long-term existence is very harmful to the environment and the health of users. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a long-acting environmental-friendly sealant with low production cost, good fireproof performance, good waterproof performance, smooth surface and strong adaptability. [0004] In order to solve the above-mentioned technical problems, the te...
