Novel fireproof coating for steel structure

Abstract

The invention provides a novel fireproof coating for a steel structure. The novel fireproof coating comprises the following components in parts by weight: 20 to 30 parts of magnesium hydroxide, 20 to30 parts of ammonium polyphosphate, 30 to 40 parts of amino resin, 10 to 20 parts of propylene resin, 20 to 25 parts of an acrylic emulsion, 20 to 30 parts of a viscosifying agent, 0.5 to 1 part of apreservative, 6 to 8 parts of a carbon-forming agent, 1 to 1.5 parts of a leveling agent, 0.5 to 1 part of a mildewproof agent, 10 to 12 parts of a stabilizing agent, 5 to 8 parts of a dispersant and30 to 40 parts of water. According to a formula provided by the invention, the fire resistance of the coating is significantly improved; and the coating provided by the invention has the advantages ofhigh transparency, stable chemical properties, high mechanical strength, good heat resistance, etc.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a novel fireproof coating for steel structures. Background technique [0002] With the increase of people's safety awareness, the application of fire retardant coatings is becoming more and more extensive. However, there are still many technical difficulties in the development of fire-resistant coatings. The main problems to be solved are to improve water resistance, shorten drying time, prolong fire-resistant time, improve storage stability, and increase decorative properties. [0003] To sum up, the indoor thin steel structure fire retardant coatings currently on the market have disadvantages such as poor water resistance, poor storage stability, short fire resistance time, long drying time, and poor decoration. Therefore, it is an inevitable trend for the fire protection of indoor steel structures to research and develop excellent performance and environment-friendly indoo...
