[0028] The preparation method of the above-mentioned water-based thin fireproof coating is as follows: weighing each raw material in proportion; then mixing each raw material evenly.
[0029] The application method of the water-based thin fireproof coating is as follows: coating the coating by airless spraying.
[0030] The paint can be sprayed by a pressure-feed spraying machine, the air pressure is 0.4-0.6Mpa, and the diameter of the nozzle opening is 6-10mm.
[0043] The preparation method of the coating is very simple. Firstly, the dry materials are weighed according to the proportion, and then added according to the order of adding amount from large to small, and finally deionized water is added and stirred evenly.
[0046] The preparation method of this coating is with embodiment 1.

Abstract
The invention belongs to the technical field of fireproof material preparation, and particularly relates to a water-based thin fireproof coating and a preparation method thereof. Each square meter of the coating is prepared from the following raw materials by weight: 25 to 37 g of silicone acrylic emulsion, 18 to 20 g of ammoniumpolyphosphate, 5 to 7 g of pentaerythritol, 11 to 13 g of melamine, 5 to 6 g of titanium dioxide, 0.3 to 0.5 g of zincoxide, 3 to 4 g of antimonytrioxide, 4 to 6 g of sodium hexametaphosphate, 0.6 to 1 g of alkyd resin, 1 to 1.2 g of diatom ooze, 0.2 to 0.4 g of methyl silicone oil, 0.6 to 0.8 g of propylene glycol phenyl ether, 1.8 to 2.2 g of sodiumcarboxymethyl cellulose and 21 to 25 g of deionized water. The coating is low in cost, simple to construct, attractive and elegant; and the water-basedcoating has stronger binding power with a base material base layer, the phenomena of cracking, pulverization, peeling and the like are difficult to occur, and after artificial thermo-oxidative aging, the fire resistance of the water-based paint is still ensured for a long time.
Description
technical field [0001] The invention belongs to the technical field of fireproof material preparation, in particular to a water-based thin fireproof paint and a preparation method thereof. Background technique [0002] The development of fireproof materials in my country is 15 to 20 years later than that of foreign industrialized countries. Although it started late, the development speed is relatively fast. Since 1958, my country has explored and conducted preliminary tests on building fireproof materials. Since 1975, my country's fireproof materials have entered a period of pioneering research and initial development. In 1978, the intumescent acrylic latex fireproof coating was developed and put into industrial trial production and engineering trial. In May 1980, the fire-resistant coating passed the technical appraisal of the Ministry of Public Security, filling the blank of domestic water-emulsion expansion fire-proof coating, and truly creating a precedent for my count...
