Abstract

The invention discloses an oil-based fireproof coating added with calcium sulfate whiskers and a preparation method thereof. The oil-based fireproof coating consists of the following raw materials in parts by weight: calcium sulfate whiskers: 18-27; perchlorinated vinyl resin: 5-10 ; Epoxy resin: 14~20; Dibutyl phthalate: 3~10; Thickener: 1~9; Pigment: 3~6; Additive: 1~5; Xylene: 25~35; Alcohol: 5-10. The preparation method includes weighing, modifying and mixing. The oil-based fireproof coating added with calcium sulfate whiskers has good stability, weather resistance, excellent fireproof effect and low raw material cost; the method for preparing the coating is simple in operation, convenient in production and low in requirements for equipment, and is suitable for industrialization Mass production.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an oily fireproof coating added with calcium sulfate whiskers and a preparation method thereof. Background technique [0002] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. The protection function refers to the function of protecting the building from the influence and damage of the environment. Different types of protected objects have different requirements for protection functions. Decorative fireproof coating is a new type of coating that integrates decoration and fireproof functions. When the fire retardant coating is applied on the combustible base material, it can usually play a decorative role. Once a fire occurs, it can preven...
