Abstract

The invention discloses a water-based waterproof coating added with calcium sulfate whiskers and a preparation method of the coating. The water-based waterproof coating is prepared from the following raw materials in parts by weight: 10-35 parts of calcium sulfate whiskers, 5-10 parts of vinyl perchloride resin, 14-20 parts of epoxy resin, 3-10 parts of dibutyl phthalate, 1-9 parts of a thickener, 3-6 parts of pigments, 1-5 parts of additives and 30-40 parts of water. The preparation method comprises the following steps: weighing; modifying; and mixing. The water-based waterproof coating added with calcium sulfate whiskers disclosed by the invention has excellent fireproof effect and anti-cracking property, low in cost of raw materials and non-toxic and environment-friendly. The method for preparing the coating is simple to operate, convenient to produce, low in requirement on equipment and suitable for industrial large-scaled production.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a water-based 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 ...
