Expanding fire-proof paint

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, adjuvant and 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 from spreading. 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.
