Abstract

The invention discloses an oily waterproof coating added with calcium sulfate whiskers and a preparation method thereof. The oily waterproof coating is composed 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; Butyl glycidyl ether: 5~10; Additive: 1~5; Xylene: 25~ 35; Pigment: 3-6. The preparation method includes weighing, modifying and mixing. The coating film of the oily waterproof paint added with calcium sulfate whiskers in the present invention is hard, strong in adhesion, excellent in water resistance and corrosion resistance, and low in raw material cost; the method for preparing the coating is simple in operation, convenient in production, and has low requirements on equipment, and is suitable for use in Industrialized mass production.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an oily waterproof 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 waterproof coating is a new type of coating that integrates decoration and waterproof functions. When the waterproof coating is applied on the combustible substrate, it can usually play a decorative role. Once a fire occurs, it can prevent the...
