Production process of water-based intumescent fire-retardant coating

Abstract

The invention relates to a production process of a water-based intumescent fire-retardant coating. Production equipment used in the production process comprises a bottom plate, a protective shell, a first grinding and crushing device, a screening and filtering device and a second grinding and crushing device. The process can solve the possible problems in a grinding and crushing process of an existing water-based intumescent fire-retardant coating raw material, which include the following problems that a, the water-based intumescent fire-retardant coating raw material is ground and crushed by means of a traditional crushing and grinding machine, a crushing and grinding effect is poor, final raw material fineness cannot meet a use requirement, and the material needs to be screened, ground and crushed again, so that production efficiency is reduced; and b, a discharge hole of the traditional crushing and grinding machine is prone to blockage, the discharge hole can only be unblocked manually after being blocked, unblocking difficulty is high, and unblocking time is long, so that labor intensity of workers is increased, discharge efficiency of the water-based intumescent fire-retardant coating raw material is reduced, and then the production efficiency of the water-based intumescent fire-retardant coating is reduced.

Description

Technical field [0001] The present invention relates to the field of water-based expansion-type fire-resistant coating, and in particular, to a water-based expansion type fire-resistant coating process. Background technique [0002] Water-based expansion fire coatings are fire-resistant coatings that are well-defined and have good decorative properties. Its fire prevention principle is that the foaming ingredients in the water-based expansion-type fire-resistant coating are thermally decomposed, and the expansion thickens form a dense fire-resistant heat insulation protective layer, while decomposing the heat absorption reaction, prevent heat transfer, and then Improve the refractory time of the product. When the water-based expansion fire coating is manufactured, it is necessary to poll the raw material to ground into a certain fine particle, and can be used to form a water-based expansion-type fire-resistant coating. [0003] At present, the existing water-based expansion-type ...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing water-based intumescent fireproof coating raw materials may encounter the following problems in the process of grinding and pulverizing: a. The water-based intumescent fireproof coating raw materials are ground and pulverized by traditional pulverizing and grinding machines. Poor, so that the final raw material fineness can not meet the needs of use, and it needs to be re-screened, ground and crushed, resulting in reduced production efficiency and increased production costs; b. The outlet of traditional crushing and grinding machinery is prone to blockage, After the blockage, the discharge port can only be dredged manually, which will undoubtedly increase the difficulty and time consumption of manual dredging, and will also increase the labor intensity of manual labor, which will correspondingly reduce the discharge efficiency of water-based intumescent fireproof coating raw materials. , thereby reducing the production efficiency of water-based intumescent fire retardant coatings
