Problems solved by technology

[0004] However, because the surface of the plastic substrate is lower than that of the metal substrate, the coating film of the paint is difficult to adhere to; the thermal deformation temperature of the plastic is low, so the heating temperature for drying and curing of the paint is limited, the release agent is poorly cleaned and the additives ooze out. There will be a phenomenon that the coating cannot form a film; and the intumescent flame retardant is easily soluble in water, which is a disadvantage of poor water resistance of the coating

Abstract

The invention belongs to the technical field of fireproof coating materials, and relates to a fireproof coating material for plastics, wherein the fireproof coating material is prepared from the following raw materials by weight: 25-30 parts of an epoxy emulsion, 10-20 parts of a highly-chlorinated polyethylene resin (particle size of 0.8-0.9 [mu]m), 20-30 parts of ammonium polyphosphate (particlesize of 0.8-0.9 [mu]m), 10-15 parts of pentaerythritol (particle size of 0.8-0.9 [mu]m), 10-15 parts of a forming agent (particle size of 0.8-0.9 [mu]m), 5-10 parts of melamine (particle size of 0.8-0.9 [mu]m), 1-2 parts of an organic curing agent, 20-30 parts of a pigment filler (particle size of 0.8-0.9 [mu]m), 1-2 parts of a defoamer, and 1-2 parts of a coupling agent. According to the presentinvention, the adhesion on the surfaces of the coating material and the plastic is improved through the plastic surface treatment before the paint coating; the expansion time of the fireproof coatingmaterial is prolonged through the requirement on the particle size of the raw material so as to improve the fire retardant performance of the fireproof coating material; and the fireproof coating material has advantages of high mechanical strength, low water absorption rate and good thermal stability, and can be widely used for the fire retarding of plastics.

Description

technical field [0001] The invention belongs to the technical field of fireproof paint and relates to a fireproof paint for plastics. Background technique [0002] Fire-resistant coatings, also known as flame-retardant coatings, belong to special functional coatings. Coating excellent fire-resistant coatings on the surface of substrates can not only play a decorative role, but also prevent corrosion, rust, acid and alkali, and smoke. At present, the fire site temperature of building fires is mostly between 800°C and 1200°C. Fire-resistant coatings can prevent the spread of flames and protect the internal structure. It is a very important fire safety product. At present, the application of plastic and plastic-steel products is becoming more and more extensive. The fire and flame retardancy of plastic is more difficult than that of wood and steel structures. Economic loss and personal injury, therefore, it is particularly important to carry out fireproof treatment for plastic...
