Preparation method of fireproof coating material

Abstract

The invention relates to a preparation method of a fireproof coating material. The preparation method comprises the following steps: (1) taking the following materials in parts by weight for standby use: 30 to 50 parts of anhydrous calcium chloride, 400 to 450 parts of pulverized silicate fiber, 50 to 70 parts of chlorinated paraffin, 30 to 50 parts of mountain flour, 8 to 12 parts of aluminum powder, 15 to 30 parts of compound zinc phosphate, 8 to 10 parts of titanium dioxide, 10 to 20 parts of mica powder, 15 to 25 parts of a foaming agent, 150 to 200 parts of a film forming agent and 150 to250 parts of deionized water; (2) adding the deionized water into a dispersing vat, starting a medium speed stirring state, adding the foaming agent in the dispersing vat, and stirring for 2 to 3 minutes; then sequentially adding the film forming agent in the formula, and stirring for 5 to 8 minutes; adding the pulverized silicate fiber, the chlorinated paraffin, the mountain flour, the aluminumpowder, the compound zinc phosphate, the titanium dioxide and the mica powder, speeding up a stirring speed to a high speed, and pulping and dispersing for 40 to 50 minutes; then slowing down a rotating speed to a medium speed state, and controlling the final consistency to be 19 to 25 DEG C, thus obtaining the fireproof coating material.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a preparation method of a novel fireproof coating. Background technique [0002] With the increase of people's safety awareness, the application of fire retardant coatings is becoming more and more extensive. However, there are still many technical difficulties in the development of fire-resistant coatings. The main problems to be solved are to improve water resistance, shorten drying time, prolong fire-resistant time, improve storage stability, and increase decoration. [0003] To sum up, the current indoor thin steel structure fire retardant coatings on the market have disadvantages such as poor water resistance, poor storage stability, short fire resistance time, long drying time, and poor decoration. Therefore, it is an inevitable trend for the fire protection of indoor steel structures to research and develop excellent performance and environment-friendly indoor thin ste...
