Embodiment 1

[0028] The preparation of a sound insulation coating for the inner wall of a warehouse of inflammable and explosive goods includes the following steps:

[0029] ①Preparation of raw materials: prepare by weight 2.2kg of ethyl orthosilicate, 4.8kg of saturated ammonia water, 9kg of glass micropowder with particle size of 2000-4000 mesh, 3.5kg of starch grafted sodium acrylate, 7kg of tin chloride dihydrate, 1kg of antimony chloride , citric acid powder 0.06kg, sodium bicarbonate powder 0.05kg, polymethyl silicone resin 52kg, silicon dioxide to polymethyl vinyl silicone rubber 9kg, vulcanizing agent 0.4kg, silane coupling agent 0.6kg, enough ethanol;

[0030] ② Dissolve ethyl orthosilicate in an appropriate amount of ethanol until it is completely dissolved, let stand for 12min-15min to obtain solution A; stir solution A at a rate of 80rpm / min-100rpm / min, while stirring for 35min-40min Add all saturated ammonia water evenly and slowly within the range, continue to stir for 5min-8...

Embodiment 2

[0037] The whole is consistent with Example 1, the difference is:

[0038] ①Preparation of raw materials: prepare by weight 2kg of ethyl orthosilicate, 4.5kg of saturated ammonia water, 8kg of glass micropowder with particle size of 2000-4000 mesh, 3kg of starch grafted sodium acrylate, 6kg of tin chloride dihydrate, 0.9kg of antimony chloride, Citric acid powder 0.05kg, sodium bicarbonate powder 0.05kg, polymethyl silicone resin 55kg, silicon dioxide to polymethyl vinyl silicone rubber 8kg, vulcanizing agent 0.4kg, silane coupling agent 0.5kg, enough ethanol;

Embodiment 3

[0040] The whole is consistent with Example 1, the difference is:

[0041] ①Preparation of raw materials: prepare 2.5kg of ethyl orthosilicate, 5kg of saturated ammonia water, 10kg of glass micropowder with particle size of 2000-4000 mesh, 5kg of starch-grafted sodium acrylate, 8kg of tin chloride dihydrate, 1.2kg of antimony chloride, Citric acid powder 0.06kg, sodium bicarbonate powder 0.06kg, polymethyl silicone resin 45kg, silicon dioxide to polymethyl vinyl silicone rubber 10kg, vulcanizing agent 0.5kg, silane coupling agent 0.7kg, enough ethanol;

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. ...
