Problems solved by technology

With the development of people's life, the requirements for such products are getting higher and higher. Ordinary flame-retardant materials can only delay the time of being burned into powder. If they continue to be burned, they will gradually become powdery and fall off, losing Protection, the wire and cable will be broken down and cause a short circuit

Abstract

The embodiment of the invention discloses a ceramic flame-retardant material applied to an electric insulation molding compound. The ceramic flame-retardant material comprises the following componentsin parts by weight: 12-46 parts of resin; 0-30 parts of a low-shrinkage additive; 0.8 to 2.0 parts of an initiator; 0.006 to 0.020 part of a polymerization inhibitor; 10 to 160 parts of a filling material; 10 to 15 parts of a flame retardant; 250 to 400 parts of vitrified powder; 4-9 parts of a release agent; and 15-70 parts of reinforced fibers. In a normal state, the cured molding compound maintains the performance of a conventional product; and under the condition of high temperature of 300-450 DEG C (with flame or without flame), a hard shell is formed after ablation, and the object burned is protected against damage. For example, a BMC or SMC or hand lay-up or pultrusion or vacuum leading-in process made by using the ceramic flame-retardant material technology is used for manufacturing a bracket, a cable trough box, a fireproof plate and the like, and the hard shell formed after ablation protects and supports the electric power and communication cable, so that the smoothness of electric power and communication is ensured, and precious time is gained for evacuation and rescue of people in case of fire.

Description

technical field [0001] The invention relates to the field of flame retardant materials, in particular to a ceramicized flame retardant material applied to electrical insulation molding compounds. Background technique. [0002] Unsaturated polyester molding compound has the advantages of high strength, good insulation performance, easy molding and processing, etc., and is widely used in power systems. With the development of people's life, the requirements for such products are getting higher and higher. Ordinary flame-retardant materials can only delay the time of being burned into powder. If they continue to be burned, they will gradually become powdery and fall off, losing Protective function, the wire and cable will be broken down and cause a short circuit. Therefore it is necessary to improve, and the technical solution to be introduced below is based on this premise. Under normal conditions, the cured molding compound maintains the properties of conventional products....
