Fireproof paint and preparation method thereof

Abstract

The invention provides fireproof paint. Raw materials comprise the following components in parts: 26 to 47 parts of acrylic emulsion, 11 to 23 parts of dipentaerythritol, 6 to 18 parts of expanded graphite, 5 to 17 parts of melamine, 2 to 11 parts of ammonium polyphosphate, 3 to 12 parts of aluminum hydroxide, 3 to 6 parts of zinc oxide, 2 to 5 parts of silicon dioxide, 4 to 11 parts of carbon fiber, 5 to 11 parts of silicon nitride fiber, 21 to 33 parts of water, 11 to 16 parts of hydroxy acrylic resin, 12 to 16 parts of polyurethane resin, 5 to 9 parts of urea, 6 to 9 parts of pentaerythritol, 6 to 11 parts of melamine phosphate, 11 to 13 parts of white carbon black, 6 to 9 parts of sodium silicate, 3 to 5 parts of titanium pigment, 2 to 3 parts of dioctyl phthalate and 2 to 4 parts of dithiocarbamate. The fireproof paint is prepared from the raw materials which are nontoxic or are lower in toxicity, and cannot cause harm to a human body, particularly to a constructor in a normal construction process; further, the made fireproof paint is transparent. The fireproof paint is of an aqueous ultrathin type; when a fire hazard happens, no toxic gas is released; the fireproof paint can be widely applied to various steel structural buildings.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof paint and a preparation method thereof. Background technique [0002] Fire retardant paint is a kind of flame retardant coating made of various materials such as film formers, flame retardants, and foaming agents; due to the extensive use of flammable materials such as wood and cloth in households, fire prevention is already a worthwhile issues raised. Existing fireproof paints can be divided into three types: facing fireproof paints, wood fireproof paints, and steel structure fireproof paints. Finishing type fire retardant paint is a new type of paint that integrates decoration and fire prevention. When it is coated on combustible substrates, it can usually play a decorative role; once a fire breaks out, it can prevent the fire from spreading, thereby To achieve the purpose of protecting combustible substrates. Intumescent fire retardant paint is widely used, and...

Problems solved by technology

Thin-coated steel structure fireproof paint can be divided into two types: solvent-based and water-based. Solvent-based fireproof paint uses a large amount of organic solvents in the production and construction process, which is harmful to the environment and construction personnel. Water-based fireproof paint is environmentally friendly and meets low pollution , the development direction of environmentally friendly coatings, but the research in our country started relatively late, and there is still a certain gap with solvent-based fireproof paints in terms of physical and chemical properties and weather resistance
