Abstract

The invention provides a sealing glue for refrigeration pipelines, wherein the sealing glue comprises, by weight, 8-12 parts of butyl rubber, 20-30 parts of polyoxypropylene diol, 1-5 parts of macromolecule polyisobutylene, 10-20 parts of isophorone diisocyanate, 3-4 parts of kaolin, 5-8 parts of talc powder, 1-2 parts of polyvinyl butyral, 1-4 parts of titanium dioxide, 5-7 parts of dimethyl silicone oil, and 2-3 parts of nanometer cerium dioxide. According to the present invention, the sealing glue does not easily produce cracking in the low temperature environment of the refrigeration pipeline, and the aging problem of the sealing glue can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of refrigeration auxiliary materials, and in particular relates to a sealant for refrigeration pipes. Background technique [0002] Sealant (sealant) is an adhesive used to fill the configuration gap to play a sealing role. It mainly introduces sealing materials that deform with the shape of the sealing surface, are not easy to flow, and have a certain degree of cohesion. They are divided into elastic sealant, liquid sealant There are three categories of padding and sealing putty. Sealants have the functions of anti-leakage, waterproof, anti-vibration, sound insulation, heat insulation, etc., and are widely used in the sealing of construction, transportation, electronic instruments and parts. [0003] Sealants can be divided into four categories according to their shape, namely: [0004] (1) Paste sealant: This type of sealant is a low-grade sealant and usually uses three main materials: oil and resin poly...
