Diatomite chloroprene type sealant

Abstract

The invention belongs to the technical field of sealants, and specifically to a diatomite chloroprene type sealant. The diatomite polychloroprene type sealant is prepared by carrying out milling and kneading the following materials according to a formula, wherein the materials comprise chloroprene rubber, butyl rubber, natural rubber, diatomite, a reinforcing agent, a filler, a viscosity regulator, a vulcanizing agent, a stabilizer and other commonly used additives. According to the present invention, the diatomite has a special structure and physical properties, the other raw materials in the formula are reasonably selected, the ratio is appropriate, and the diatomite chloroprene type sealant has characteristics of good anti-aging performance, good weather resistance, strong heat resistance, strong wear resistance, rare sagging, good surface smoothness, environmental protection, and long service life, and can be used for family decoration and other fields.

Description

technical field [0001] The invention belongs to the technical field of sealants, and in particular relates to a diatomite neoprene sealant used in the fields of home decoration and the like. Background technique [0002] Sealant is a sealing material that deforms according to the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the configuration gap and seal it. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Usually dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as the base material, and inert fillers such as talcum powder, clay, carbon black, titanium dioxide and asbestos are added. Plasticizers, solvents, curing agents, accelerators, etc. It can be divided into three categories: elastic sealant, liquid gasket and sealing putty. Widely used in construction, transpo...

AI Technical Summary

Problems solved by technology

[0007] Existing neoprene has relatively simple functions, and it is urgent to study a kind of neoprene sealant with comprehensive functions, good anti-aging performance, long service life, and good smoothness at the same time.
