Abstract

The invention discloses anti-aging polyurethane flame-retardant paint for electric fire-fighting equipment, and relates to the technical field of fire prevention and flame retardance. The flame-retardant polyurethane composite material is prepared from the following raw materials in parts by weight: 100 parts of polyurethane resin, 20-100 parts of a flame retardant, 10-60 parts of a charring agent, 20-80 parts of a foaming agent, 0.05-5 parts of a wetting agent, 0.5-5 parts of a defoaming agent, 0.5-10 parts of a dispersing agent, 0.5-10 parts of an anti-settling agent, 1-70 parts of pigment and filler, 0.01-3 parts of a flatting agent, 1-100 parts of a diluent, 10-100 parts of a curing agent and 1-20 parts of a light stabilizer. The invention also provides a preparation method and application of the polyurethane flame-retardant paint. The light-aging-resistant polyurethane flame-retardant paint has the beneficial effects that the problems that polyurethane paint is extremely easy to burn and is easy to age by light are solved, and the light-aging-resistant polyurethane flame-retardant paint has the properties of high adhesive force, good water resistance, strong weather resistance and the like while solving the fireproof problem, and can meet the fireproof requirements of fire-fighting pipelines of power equipment.

Description

technical field [0001] The invention relates to the technical field of fire and flame retardant, in particular to an aging-resistant polyurethane flame retardant paint for electric power fire equipment, and a preparation method and application thereof. Background technique [0002] Large-scale power equipment is often placed in suburban or remote areas. When a fire occurs, it is difficult for fire rescue to reach the fire scene at the first time. Therefore, it is necessary to ensure that the fire-fighting facilities of large-scale power equipment maintain normal operation in the face of fire. It is possible to reduce accident disasters and economic losses. However, when a fire occurs in the electrical equipment, the flame may burn to the firefighting facility, causing it to deform or melt, resulting in the inability to play its due fire-fighting effect.
