Abstract

The invention relates to an expanded transparent fire-retardant paint which is composed of the following components in parts by mass: 50-55 parts of formaldehyde, 20-30 parts of urea, 15-25 parts of dicyandiamide, 30-35 parts of isopropanol, 15-25 parts of titanium white, 5-10 parts of formic acid, 1-5 parts of flame retardant, 5-10 parts of pentaerythritol, 2-5 parts of chlorinated paraffin, 4-8 parts of sodium hydroxide, 1-5 parts of phosphoric acid, 30-40 parts of phosphorus oxychloride, 25-30 parts of chloroethanol and 10-15 parts of distilled water. The fire-retardant time of the coated film of the product is 140-150 minutes when the thickness is 0.5-1.5 mm; the product has better expanded heat-insulating property at high temperature, and the height of the expansion layer is up to 2-2.5cm; the product is transparent, has the advantages of low toxicity and favorable decorative property, and is easy for construction; and the product has excellent fire retardancy (reaching Level 1 in national standard), and can be widely produced and continuously substitute the existing material.

Description

technical field [0001] The application belongs to the field of fireproof materials, in particular to an intumescent transparent fireproof coating. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of flammable substrates to change the combustion characteristics of the material surface and retard the rapid spread of fire; or applied to building components to improve the fire resistance limit of components, called fire retardant coatings. Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating...
