Fire retardation fireproof material and preparation method thereof

Abstract

The present invention relates to a fire retardation fireproof material and a preparation method thereof. The fire retardation fireproof material comprises, by mass, 100 parts of a silicon rubber, 5-30 parts of an organic siloxane, 1-10 parts of zinc oxide, 20-200 parts of a fireproof filler, and 20-200 parts of white carbon black. According to the present invention, the processed product has good mechanical property (such as tensile strength, elongation, and tearing strength), good fire retardation and good electrical property (such as breakdown strength), burns at a certain temperature or under an aerobic condition, and can form a rigid housing, wherein the housing can form a compact fireproof layer at a temperature of more than 600 DEG C; fire retardation, temperature resistance and fire resistance of the material can be substantially improved in the case of addition of zinc oxide; the addition amounts of the fireproof filler and the white carbon black can be substantially improved; and the cost of the fire retardation material can be substantially reduced under the premise of assurance of good tensile strength, tear strength, breakdown strength, and fire resistance.

Description

technical field [0001] The invention relates to the technology in the field of refractory materials, and in particular provides a flame-retardant refractory material and a preparation method. Background technique [0002] Usually, silicone rubber itself is not flame retardant or fire-resistant. In a fire accident, wires and cables are not fire-resistant and easy to burn in case of fire. This field lacks a fire-resistant silicone rubber. It is required not only to have the excellent characteristics of rubber during normal use, It also has good flame retardancy and fire resistance. The products made by using it can play a certain protective role in the fire, and can reduce the loss and harm caused to people in the fire. [0003] At present, most fire-resistant and flame-retardant cables use magnesium oxide mineral insulation or mica tape winding to achieve fire-resistant functions. [0004] Magnesia mineral fire-resistant insulated cables have the following disadvantages in t...

Problems solved by technology

[0004] Magnesia mineral fire-resistant insulated cables have the following disadvantages in the manufacture and application: First, the production and processing of magnesium oxide mineral fire-resistant insulated cables cannot be processed as conveniently as polymer materials, and magnesium oxide mineral refractory insulated cables require special production and processing equipment. Expensive, high equipment cost; second, because the outer sheath of the magnesia mineral refractory insulated cable is all copper, the price of copper is high, making the production cost higher, which is limited to a certain extent in practical application; third , due to the special re
