Problems solved by technology

However, some materials used in the fire retardant coating are highly toxic and easy to produce toxic smoke when burned, which is not conducive to popularization and utilization.
The above-mentioned fireproof materials can be applied to power equipment, which can meet the fireproof requirements of power equipment to varying degrees, but the carbonization layer density of fireproof materials is not enough, the amount of smoke is relatively large, and the weather resistance performance needs to be improved

Embodiment 1

[0022] Embodiment 1: An environmentally friendly fireproof material for electric equipment, made of the following raw materials in parts by weight: 55 parts of modified epoxy resin, 35 parts of fluorocarbon resin, 75 parts of flame retardant, 6 parts of expanded graphite, silicic acid 7 parts of aluminum fiber, 5 parts of molecular sieve.

[0023] The flame retardant is made from the tetraphenyl bisphenol A diphosphate, melamine phosphate and dipentaerythritol in a weight ratio of 3:1:1.5.

[0024] The particle size of the expanded graphite is 200 μm. The test shows that different particle sizes of expanded graphite have different effects on the strength of the carbon layer in the expansion system. If the particle size of expanded graphite is too small, the specific surface area increases rapidly and the cooling effect is remarkable, but it is not conducive to the improvement of the density and strength of the carbon layer; while the particle size If the diameter is too large...

Embodiment 2

[0031] Embodiment 2: An environmentally friendly fireproof material for electric equipment, made of the following raw materials in parts by weight: 50 parts of modified epoxy resin, 30 parts of fluorocarbon resin, 70 parts of flame retardant, 5 parts of expanded graphite, silicic acid Aluminum fiber 5 parts, molecular sieve 7 parts.

[0032] The flame retardant is made from the tetraphenyl bisphenol A diphosphate, melamine phosphate and dipentaerythritol in a weight ratio of 3:1:1.5.

[0033] The particle size of the expanded graphite is 200 μm.

[0034] A method for preparing an environment-friendly fireproof material for electric equipment, comprising the following steps:

[0035] Step S1: Weigh the flame retardant, expanded graphite and aluminum silicate fiber in the above parts by weight and mix them vigorously in a high-shear homogenizer until they are completely uniformly dispersed to obtain a homogeneous material;

Abstract

The invention provides an environment-friendly fireproof material for electrical equipment and a preparation method of the environment-friendly fireproof material, and belongs to the fields of fireproof materials and preparation technologies thereof. The environment-friendly fireproof material for the electrical equipment is characterized by being prepared from the following raw materials in parts by weight: 50 to 60 parts of modified epoxy resin, 30 to 40 parts of fluorocarbon resin, 60 to 90 parts of a fire retardant, 3 to 10 parts of expanded graphite, 3 to 10 parts of alumina silicate fiber and 2 to 8 parts of molecular sieves. The fireproof material provided by the invention is applied to fire protection of the electrical equipment, and is high in crack resistance, water resistance and weather resistance and good in expansion character; meanwhile, the heat release rate of a base material in a burning condition can be obviously reduced, and the quality loss is reduced; moreover, the fireproof material is small in smoke production quantity and good in environmental protection effect.

Description

technical field [0001] The invention belongs to the technical field of fireproof materials and their preparation, and in particular relates to an environment-friendly fireproof material for electric equipment and a preparation method thereof. Background technique [0002] With the rapid development of modern technology and the power industry, power equipment has become an important part of our daily work and life, providing us with services such as industrial power, civil power, telecommunications, data transmission, Internet, business, finance, Technology, medical and other multi-faceted power services. Our reliance on electricity has also become increasingly intense. Compared with the past situation, the power equipment itself has been highly sophisticated, the functions are more and more complete, and the cost has become more and more expensive, so a small fire in the power equipment will cause very serious consequences. This includes not only the loss of the equipment ...
