Problems solved by technology

[0002] Existing binders are mainly based on the properties of the resin used to adapt to the environment. At present, the high-temperature-resistant binders commonly used in the market are not acid-resistant, and the acid-resistant binders cannot withstand high temperatures. Adhesive, the hardness of the entire adhesive layer cannot meet the requirements of actual use after curing

Embodiment 1

[0020] An acid-resistant and high-temperature-resistant elastic adhesive has a resin mixture and a curing agent, wherein the components of the resin mixture are:

[0021] Trimethoxysilane 30wt%

[0022] Coupling agent 2wt%

[0023] Dimethicone resin 10wt%

[0024] Silicone resin 30wt%

[0025] Nano active calcium carbonate 18wt%

[0026] Nano Aluminum Hydroxide 10wt%

[0027] Mix and stir the above materials in proportion to make a resin mixture;

[0028] When in use, the mass ratio of the resin mixture to the curing agent is 10:1.

Abstract

The invention relates to an adhesive, particularly an acid-resistant high-temperature-resistant elastic adhesive which is prepared from a component A and a component B, wherein the component A is a resin mixture, and the component B is a fatty amine modified curing agent or aliphatic curing agent; the resin mixture is prepared from 25-30 wt% of trimethoxy silane, 2-8 wt% of coupling agent, 10-15 wt% of dimethyl silicone epoxy resin, 20-35 wt% of organic silicone resin, 15-25 wt% of nano activated calcium carbonate and 10-12 wt% of nano aluminum hydroxide; and when in use, the component A and component B are mixed in the mass ratio of 10:1. The invention solves the problem of contradiction between high temperature resistance and acid resistance in the existing adhesive.

Description

technical field [0001] The invention relates to a binder, in particular to an acid-resistant and high-temperature resistant binder. Background technique [0002] Existing binders are mainly based on the properties of the resin used to adapt to the environment. At present, the high-temperature-resistant binders commonly used in the market are not acid-resistant, and the acid-resistant binders cannot withstand high temperatures. Adhesive, the hardness of the entire adhesive layer after curing cannot meet the requirements for actual use. Contents of the invention [0003] In order to overcome the above-mentioned defects, the technical problem to be solved by the present invention is to provide an acid-resistant and high-temperature resistant elastic adhesive for the problems existing in existing adhesives between high temperature resistance and acid resistance. [0004] In order to overcome the defects existing in the background technology, the technical solution adopted by ...
