Problems solved by technology

[0003] At present, the main film-forming substance of thin fireproof coatings is vinyl acetate-ethylene copolymer emulsion. However, this type of fireproof coating has the following problems: 1. The water resistance is poor, and foaming, whitening, and blooming will occur if the time is too long, which will affect the fireproof rating; 2. When encountering an open flame, the emulsion itself will burn, and Release different levels of harmful gases
However, the temperature resistance, water resistance and fire protection level of the existing inorganic coatings still need to be improved.

preparation example Construction

[0043] The embodiment of the present application also provides a method for preparing the above-mentioned organic-inorganic hybrid fireproof coating, which includes the following steps:

[0044] S1. Add cellulose to part of the water, and stir at 800-1000 rpm until the cellulose is fully dissolved to form a cellulose solution.

[0045] S2. Add water-based dispersant, water-based wetting agent, water-based defoamer, film-forming aid, and water to the cellulose solution, and stir at 300-400 rpm for 5-10 minutes.

[0046] S3. Add rutile titanium dioxide, filler additives and flame retardants, and stir at 800-1000 rpm for 15-20 minutes. It is enough to detect that there are no particles, indicating that the pigments, fillers, and flame retardants have been uniformly dispersed in the solution. If particles are detected, it indicates that there are raw material particles that are not evenly dispersed.

[0047] S4. Add vinyl acetate-ethylene copolymer emulsion, and stir at 400-600 r...

Abstract

The embodiment of the invention provides an organic-inorganic hybrid fireproof coating and a preparation method thereof, and relates to the field of fireproof coatings. The fireproof coating is prepared from, by mass, 15-22% of potash water glass, 5-10% of a vinyl acetate-ethylene copolymer emulsion, 0.2-0.6% of cellulose, 0.2-0.5% of a water-based dispersant, 0.1-0.3% of a water-based wetting agent, 0.3-0.5% of a water-based defoaming agent, 2.2-4.1% of a coalescing agent, 13-28% of a filler aid, 20-30% of a flame retardant and 22-23.6% of water. The preparation method comprises the followingsteps: adding the dispersant, the wetting agent, the defoaming agent, the coalescing agent and water into a cellulose solution, and stirring; adding rutile titanium dioxide, the filler aid and the flame retardant, and stirring; adding the vinyl acetate-ethylene copolymer emulsion, and stirring; and adding potash water glass, and stirring. The fireproof coating has the characteristics of high temperature resistance, good water resistance, high fireproof grade, high drying speed and the like.

Description

technical field [0001] The present application relates to the field of fireproof coatings, in particular to an organic-inorganic hybrid fireproof coating and a preparation method thereof. Background technique [0002] In densely populated areas, such as: railway stations, high-speed rail stations, moving rail stations, airports, shopping malls, gymnasiums, schools and other public places, steel structures are often used as the main building, and fire-resistant coatings are applied on the surface of the steel structures according to the fire-proof rating. Thereby protecting the main body of the building from collapsing in case of fire. [0003] At present, the main film-forming substance of thin fireproof coatings is vinyl acetate-ethylene copolymer emulsion. However, this type of fireproof coating has the following problems: 1. The water resistance is poor, and foaming, whitening, and blooming will occur if the time is too long, which will affect the fireproof rating; 2. W...
