Problems solved by technology

[0003] Brushing fire-resistant coatings is a commonly used protection method for steel structures. However, the existing fire-resistant coatings have low fire resistance limit, poor durability and weather resistance, and cannot meet the requirements of the society.
[0004] The paint has a high viscosity after being mixed with water. It needs to be heated and stirred during use, which is very convenient for us to use. Traditional paint mixing equipment cannot achieve this effect.

Abstract

The invention discloses a novel fireproof coating for a thick steel structure. The novel fireproof coating comprises, by weight, 65-90 parts of acrylic resin, 6-20 parts of vinyl acetate-styrene copolymerization emulsion, 4-15 parts of amino resin, 25-40 parts of bentonite, 10-20 parts of nano calcium carbonate, 20-40 parts of ammonium polyphosphate, 10-25 parts of melamine, 8-22 parts of pentaerythritol, 2-7 parts of chlorcosane, 1-3 parts of hydroxyethyl cellulose, 2-4.5 parts of sodium hexametaphosphate, 0.5-3 parts of a defoaming agent, 3-12 parts of butyl acetate and 1-10 parts of S-100A solvent. The novel fireproof coating for the thick steel structure is high in adhesive force, good in fireproof heat insulation performance, high in duration of fire resistance and excellent in durability and weathering resistance.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a novel thick steel structure fireproof coating and a stirring device for the coating. Background technique [0002] As a new type of building structure in recent years, steel structure has been widely used in construction due to its flexible structure, light weight, high strength, good shock resistance and deformation, short construction period, and easy maintenance. Under the action of fire and high temperature, the mechanical properties of steel structures such as yield strength, elastic modulus, and load capacity will decrease with the increase of temperature. Therefore, steel structure buildings must take some corresponding fire prevention measures to improve the fire resistance limit of steel structures, meet the requirements of fire protection design codes, and prevent excessive deformation and collapse due to rapid temperature rises to critical temperatures in ...
