In recent years, with the rapid development of the economy, the concept of fire protection is gradually improving. In addition to effective escape space planning for buildings, the selection of fire-resistant building materials is also particularly important. When the existing fire-resistant coatings are baked at high temperatures, they will Melting, dripping or cracking and peeling, etc., cannot provide effective fire protection

Abstract
The invention discloses a waterborne intumescent fireproof paint, belonging to the field of paints. The waterborne intumescent fireproof paint comprises, by weight, 15-20 parts of a polyvinyl acetateemulsion, 7-10 parts of a polyorganosiloxane emulsion, 10-15 parts of ammonium polyphosphate, 8-12 parts of dipentaerythritol, 10-15 parts of chlorinated paraffin, 10-12 parts of waterborne melamine formaldehyde resin, 4-7 parts of titanium dioxide, 1-3 parts of a sodium hexametaphosphate solution, 1-3 parts of azodicarbonamide and 18-25 parts of water. The waterborne intumescent fireproof paint of the invention has the advantages of good fireproof and heat insulation performance, good bonding force, high strength and capacity of withstanding the influence of high-and-low-temperature circulation; and a coating formed by the paint has good water resistance, acid resistance and salt corrosion resistance, and is hard to fall off, stable in storage, good in decorative performance and convenient to construct.
Description
technical field [0001] The invention relates to the field of coatings, in particular to a water-based swelling fireproof coating. Background technique [0002] In terms of fire prevention mechanism, fire retardant coatings are generally divided into two types: intumescent and non-intumescent. The non-aqueous intumescent fire retardant coating achieves the purpose of flame retardant and fire prevention by its own high flame retardancy or non-combustibility. In order 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 must be added. This produces large amounts of toxic gas. The water-based intumescent fireproof coating means that the coating film is heated and expands to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to the substrate. A series of physical and chemical reactions that occur during fire prevention a...
