Preparation process and device of high-temperature-resistant fireproof coating for building

Abstract

The invention relates to the technical field of building coating production, and discloses a preparation process of a high-temperature-resistant fireproof coating for a building. The preparation process comprises the following steps: mixing solid raw materials, grinding in a disc type grinder, screening with a 40-mesh sieve, adding the mixture obtained in the step 1 into a stirring barrel, injecting 20-30 parts of 40-60 DEG C warm water, stirring, and mixing, stirring for 2 hours at the rotating speed of 900-1500 revolutions per minute; sequentially adding a potassium silicate solution, a thickening agent, emulsion, a suspending agent, a curing agent, a drier and glue, stirring for 0.5 hours at the rotating speed of 80-100 rpm to obtain the corresponding coating. The invention provides a preparation device of the high-temperature-resistant fireproof coating for the building. The preparation device comprises a stirring barrel and a rotating stirring shaft arranged in the stirring barrel, the stirring shaft is coaxially and fixedly connected with stirring support, a plurality of connecting rods for mounting stirring rods are distributed on the circumferential surface of the stirringsupport in a circumferential array manner, and rotating brush seats for cleaning are arranged in the stirring rods, so that stirring and cleaning functions are achieved, and the cleaning efficiency isimproved.

Description

technical field [0001] The disclosure belongs to the technical field of architectural paint production, and in particular relates to a preparation process and a device for a high-temperature-resistant fireproof paint for architectural use. Background technique [0002] 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 coating. Fireproof coating is a special coating 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 improve the fire resistance limit of the coated material. It is applied to the surface of flammable substrates to change the combustion characteristics of the material surface and retard the rapid spread of ...

Problems solved by technology

[0003] The existing fireproof coating preparation device is laborious to clean and needs to be cleaned manually. The chemical agents contained in the coating are harmful to the human body. At the same time, the manual cleaning efficiency is slow and difficult to operate. Therefore, we propose a high temperature resistant fireproof coating for construction The preparation process and its device
