Sound insulation coating for inner wall surface of flammable and explosive warehouse and preparation method thereof

Abstract

The invention discloses a sound insulation coating for the inner wall surface of a flammable and explosive warehouse and a preparation method of the sound insulation coating. The sound insulation coating is composed of a matrix and a functional filler, wherein the matrix is a silicon-based resin matrix prepared by taking starch grafted sodium acrylate, polymethyl silicone resin, silicon dioxide p-polymethyl vinyl silicone rubber, a vulcanizing agent and a silane coupling agent as raw materials; the functional filler is three-layer structure conductive resonance particles prepared by taking ethyl orthosilicate, ammonia water, glass micro-powder, tin chloride dehydrate, antimony chloride, citric acid powder and sodium bicarbonate powder as raw materials, and the three-layer structure specifically comprises the glass micro-powder, an active silicon dioxide substrate layer and an antimony-doped tin oxide outer coating layer from inside to outside. The sound insulation coating has the advantages of static electricity removal, flame retardance, nonflammability, sound insulation and shock absorption.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a sound insulation coating used for the inner wall of a warehouse of inflammable and explosive goods and a manufacturing method thereof. Background technique [0002] Warehouses used to store inflammable and explosive materials in the prior art generally include: 1. Keep away from other buildings and have good ventilation; 2. Fireworks are strictly prohibited. 3. Flammable and explosive items must be stored in special warehouses separately, and should not be placed randomly. When storing calcium carbide, attention should be paid to moisture-proof, and calcium carbide and other materials are not allowed to be shipped in rainy days. In all technical requirements, there is no specification for the inner wall coating. In fact, choosing a suitable coating for inner wall protection can greatly reduce the risk of deflagration in the warehouse, such as the use of antistatic coatings. ...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, there is no coating material specially designed for the interior walls of flammable and explosive warehouses, and the existing professional coatings only have antistatic function, but in fact, dehumidification, Self-flammability, sound insulation, shock absorption and other technical properties have obvious excellent effects on improving the safety performance of flammable and explosive warehouses
