Composite silicone rubber fireproof coating and fireproof blocking plate comprising same

Abstract

The invention discloses a composite silicone rubber fireproof coating which comprises the following components in percentage by weight: 35%-45% of polymerization resin, 5%-10% of ethyl acetate, 30%-35% of a flame retardant, 6%-11% of expanded graphite, 8%-10% of an auxiliary agent and 7%-10% of a curing agent. The fireproof blocking plate comprises a galvanized steel sheet, the outer surface of the galvanized steel sheet is coated with the composite silicone rubber fireproof coating, and the composite silicone rubber fireproof coating is coated with a fireproof coating material. A product is formed by compounding multiple layers, wherein the first layer is a galvanized steel sheet, the second layer is a composite silicone rubber fireproof coating, and the third layer is a fireproof coatingmaterial, and the fireproof function is achieved through multi-layer compounding. A steel mesh is added into the silicone rubber coating, so that a carbon layer is stable after fire expansion.

Description

technical field [0001] The invention relates to the field of fireproof sealing materials, in particular to a composite silicone rubber fireproof coating and a fireproof sealing plate comprising the same. Background technique [0002] At present, fireproof sealing materials are used at home and abroad to seal the holes, so as to effectively prevent the flame from spreading through the holes. Commonly used fireproof sealing materials include: fireproof rock wool board, organic blocking material, inorganic blocking material and fire retardant bag, etc. [0003] However, the existing plugging material is too thick, which makes it difficult to install the product. In addition, the weather resistance is too poor, and the product is prone to embrittlement and fracture in a long-term humid and vibrating environment. [0004] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0005] Aiming at the above-ment...
