Embodiment 1

[0038] Take 7 parts of methyl silicone oil, 100 parts of petroleum ether, and 80 parts of ammonium polyphosphate, keep it at a reflux temperature of 60-100°C for 1-1.5 hours, evaporate the petroleum ether, and dry it at 110°C for about 1 hour to obtain a fluid powder product. At 25°C, its solubility is 1 / 20 of that without treatment, and the solubility is greatly reduced.

Embodiment 2

[0040]Take 7.5 parts of simethicone oil, 100 parts of petroleum ether, and 80 parts of ammonium polyphosphate, keep it at a reflux temperature of 60-100°C for 1-1.5 hours, evaporate the petroleum ether, and dry at 110°C for about 1 hour to obtain a fluid powder product. At 25°C, its solubility is 1 / 20 of that before treatment.

Embodiment 3

[0043] 12 parts of acrylic resin, 35 parts of ordinary ammonium polyphosphate, 10 parts of melamine, 10 parts of pentaerythritol, 8 parts of titanium dioxide, 7 parts of chlorinated paraffin, appropriate amount of solvent and thinner. Preparation method: Dissolve the acrylic resin with solvent and diluent first, put it into the batching tank together with the above-mentioned other components, stir evenly, grind it with a three-roll mill until the fineness is qualified, and disperse it evenly with a high-speed mixer to obtain a fireproof coating. Apply to the substrate by brushing.

Abstract

The expansive fire-resisting paint contains the components of acrylic resin, catalyst, carbon-forming agent, foaming agent, fire-resisting agent, reinforcing agent, pigment filling material, adjuvantand smoke inhibiting agent, and is characterized by that it utilizes the modification of acrylic resin, surface treatment of catalyst and addition of smoke inhibiting agent to raise comprehensive property of paint. When the paint film is heated and expanded, it can be formed into fire-resistant carbonized layer with three-D space structure, and can release fire-resisting gas to prevent flame fromspreading. Said paint is suitable for steel structure, and material and electric cable, etc.

Description

technical field [0001] The invention relates to a fireproof paint, in particular to an intumescent fireproof paint, which can be used as a fireproof paint for steel structures, a decorative surface fireproof paint, and a fireproof paint for cables. Background technique [0002] In terms of fire prevention mechanism, fire retardant coatings are generally divided into two types: intumescent and non-intumescent. Non-intumescent fire retardant coatings rely on their own high flame retardancy or non-combustibility to achieve the purpose of flame retardant and fire prevention. To achieve a good fire prevention effect, it must be coated very thickly, and a large amount of halogen, nitrogen, phosphorus and other flame retardants are added to produce Lots of toxic gas. Intumescent fireproof coating means that the coating film expands when heated to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to the substrate. A seri...
