Abstract

The invention provides an expanded type aqueous facing fireproof coating, which comprises the following components by weight: 10% to 30% of styrene-acrylic emulsion, 20% to 30% of ammonium polyphosphate, 10% to 20% of pentaerythritol, 15% to 25% of melamine, 5% to 10% of titanium dioxide, 2% to 8% of aluminum hydroxide, 1% to 5% of zinc borate, 1% to 2% of chlorinated paraffin, 0.05% to 0.2% of antiseptic, 0.1% to 0.2% of dispersing agent, 0.3% to 1.0% of film-forming auxiliary, 0.1% to 0.5% of cellulose ether, 0.5% to 2.0% of hydroxy silicone oil and the balance of water. The expanded type aqueous facing fireproof coating, provided by the invention, has the advantages of excellent water resistance and salt mist resistance, excellent adhesion and flexibility, good storage stability, no layering, no fineness change and no packing phenomenon, excellent waterproof resistance, smooth and fine coating film, no toxicity and pollution, and environment-friendliness.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an intumescent water-based decorative fireproof coating and a preparation method thereof. Background technique [0002] With the continuous development of my country's economic construction, the development and construction of various high-rise buildings, underground projects, office buildings, and entertainment venues, the high-grade and luxurious interior decoration has further expanded the use of building decoration materials, followed by Increased fire hazard. In order to better match fire protection and decoration, people have higher and higher requirements for decorative fireproof coatings, and their applications are becoming more and more extensive. Therefore, decorative decorative fireproof coatings will have a broader application and development prospect. [0003] Fire retardant coatings, also known as flame retardant coatings, are special functional coatings. They are painted on...
