Problems solved by technology

At present, people have successively developed fire-resistant and flame-retardant coatings based on inorganic metal compound flame retardants, phosphorus-based flame retardants, nitrogen-based flame retardants and silicon-based flame retardants. Although the raw material components have the characteristics of low toxicity, But its alkali resistance is generally poor

Abstract

The invention provides an alkali-resistant flame-retardation priming paint. The alkali-resistant flame-retardation priming paint comprises the following components: 35-38 parts of water, 0.2-0.5 partsof cellulose, 0.1-0.3 parts of a neutralizer, 0.4-0.8 parts of propylene glycol, 0.5-0.9 parts of a film-formation auxiliary agent, 0.1-0.3 parts of a wetting agent, 0.4-0.8 parts of a dispersing agent, 4.5-5.5 parts of titanium dioxide, 4.5-5.5 parts of powdered steatile, 18-21 parts of heavy calcium carbonate, 9-11 parts of kaolin, 0.1-0.3 parts of an antiseptic, 9-11 parts of ammonium polyphosphate, 10-15 parts of an emulsion, 0.2-0.6 parts of a thickening agent, and 0.2-0.3 parts of an antifoaming agent. The alkali-resistant flame-retardation priming paint is used for constructing a multilayer painting system, and is capable of increasing the adhesive force, sealing performance, and flame retardation and alkali resistant performance of the system.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an alkali-resistant and flame-retardant primer. Background technique [0002] Halogen-free flame retardants are more and more used in fire-proof and flame-retardant coatings due to their low smoke generation and no toxic and corrosive gases during combustion, especially inorganic phosphorus-nitrogen-based halogen-free flame retardants due to their raw material resources Abundant and low price, it has become the leading product among halogen-free flame retardants. However, the flame retardant mechanism of inorganic phosphorus nitrogen-based halogen-free flame retardants is that the acid source and carbon source form a carbon layer flame retardant structure through esterification, so more organic compounds need to be added as carbon sources in the coating production process to make the coating The VOC value is greatly improved. At present, people have successively devel...
