Preparation method of transparent fireproof paint

Abstract

The invention provides a preparation method of a transparent fireproof paint, relating to the technical field of chemical industry. The transparent fireproof paint is composed of the following raw materials: 17-19 parts of urea, 26-28 parts of formaldehyde, 90-100 parts of ethanol, 0.1-0.2 part of phosphoric acid, 0.2-0.4 part of starch, 0.1-0.3 part of sodium hydroxide, 0.1-0.3 part of calcium powder, 0.1-0.3 part of formic acid, 25-27 parts of water, 0.3-0.4 part of anti-aging agent and 0.1-0.3 part of accelerator. The method has the advantages of convenient and simple preparation process, accessible raw materials and low equipment investment, and is convenient for operation. The prepared transparent fireproof material fireproof paint has the advantages of environmental protection, no pollution, high purity, favorable use effect, favorable high-temperature resistance and high safety and reliability.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a preparation method of a transparent fireproof coating. Background technique [0002] Transparent fireproof coatings are used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and ensure the original state of the substrate. It is applied to the surface of flammable substrates to change the surface of the material. Combustion characteristics, retarding the rapid spread of fire; or special coatings applied to building components to improve the fire resistance limit of components, called fire retardant coatings. Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fi...

AI Technical Summary

Problems solved by technology

Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating, or flame retardant Coatings, but in this kind of coatings, organic solvents such as toluene and xylene are generally used to dilute them, so they are also toxic; at the same time, the construction is inconvenient, the overall cost is high, the construction period is short and long, and the environmental protection is relatively poor, but even with so many However, it has to be used at present, but due to the lack of technology in the production of waterproof coatings, the degree of choice is very low. Most of the fire-resistant coatings used in the market are still this type of fire-resistant coatings.
