Flame-retardant rubber

Abstract

The invention discloses flame-retardant rubber. The flame-retardant rubber is prepared from, by weight, 3-5 parts of calcium carbonate, 6-7 parts of zinc oxide, 12-14 parts of chlorinated paraffin, 2-4 parts of stearic acid, 1-5 parts of argil, 2-3 parts of magnesium chloride, 2-4 parts of fire retardant, 50-60 parts of butadiene styrene rubber and 10-13 parts of natural rubber. The prepared flame-retardant rubber is good in flame retardant effect, can effectively delay ignition and reduce the flame spreading speed and has good application prospects.

Description

technical field

[0001] The invention belongs to the field of rubber, and in particular relates to a flame-retardant rubber. Background technique

[0002] Usually, people's understanding of flame-retardant rubber is that rubber does not burn under normal combustion conditions. In fact, this is a misunderstanding. Because, there is no so-called general combustion conditions. It is impossible for a polymer product to prevent combustion in some way, all it can do is change the way it burns. If the polymer is left to burn for a long enough time, at a high enough temperature and with enough oxygen, any fire prevention measures will be ineffective. Therefore, the effective fire prevention method is to cut off the oxygen supply required for combustion or to isolate the heat source. The principle of the latter is: when a substance is heated, it releases crystal water, absorbs heat or improves thermal conductivity, which can also act as a flame retardant. Therefore, , when burning ...
