Problems solved by technology

Although polyurethane foam has a certain flame-retardant effect after being treated with a flame retardant, it also has the possibility of being ignited. Once ignited, polyurethane itself is a high-flammability substance. When it burns, it burns fast and the temperature is higher than 2000℃, large amount of smoke and toxic gas

Embodiment Construction

[0006] Melt 20-30 parts of modified high-chlorinated polyethylene with 2-3 parts of butyl acetate to form a 30% solution under high-speed stirring, and mix 10-15 parts of internal vinyl acid resin and 4-5 parts of 50% epoxy resin Add 1-2 parts of organic expansive soil into the solution under low-speed stirring, and stir for about ten minutes; then add 2-5 parts of melamine, 6-10 parts of pentaerythritol, 6-10 parts of zinc aluminate, 13-15 parts Ammonium polyphosphate, 2-6 parts of chlorinated paraffin, 2-6 parts of titanium dioxide, 4-8 parts of flame retardant, etc., after stirring for 30 minutes, send them to the grinder for grinding, and stop grinding after the detection fineness reaches 90μm; Next, add 1-2 parts of defoamer, and add all the remaining 8-12 parts of xylene and stir evenly.

[0007] After the preparation was successfully prepared, several flame resistance tests were carried out. A set of test data is shown below:

[0008] Data 1 was inspected by Beijing Bu...

Abstract

The invention provides a special fireproof paint for a PUF thermal insulation material. The paint comprises modified high chlorinated polyethylene, acrylic resin, 50% of epoxy resin, melamine, pentaerythritol, zinc aluminate, ammonium polyphosphate, chlorinated paraffin, titanium dioxide, a fire retardant, antimonony oxide, organic expansive soil, an antifoaming agent, xylene and butyl acetate. The smoke suppression system employed in the invention has been reported at home and abroad and mainly comprises ammonium polyphosphate, melamine, pentaerythritol and other flame retardant substances. In case of fire, HCL containing chloride reacts with antimonony oxide to form a compact and hard antimony chloride non-combustible protective layer, thereby substantially prolongating the period of resisting burning of the PUF thermal insulation material. According to results of experiments, when PUF having a fireproof paint with a thickness of 2 mm is directly burned with alcohol burner flame at a temperature of 1000 DEG C for 90 minutes, a compact hard flame retardant layer is formed on the surface of the PUF; although 2 cm of the PUF is carbonized, no open flame appears.

Description

technical field [0001] The invention relates to a fireproof coating specially developed for polyurethane foam insulation materials, in particular to a special fireproof coating for rigid polyurethane foam insulation materials and a preparation method thereof. Background technique [0002] Rigid polyurethane foam (PUF) is a high-performance thermal insulation and fireproof material, which has the advantages of good thermal insulation effect, strong fireproof performance, strong adhesion to the base layer, no cavity, corrosion resistance, and long service life. There is a molding method of rigid polyurethane foam (PUF), which is to spray liquid raw materials on substrates of any shape, so it is widely used in the field of building insulation, especially in some large domestic factories and entertainment venues. Inexpensive insulation material is used as the insulation material of the roof. Although polyurethane foam has a certain flame-retardant effect after being treated wit...
