Abstract

The invention discloses flame retardant rubber, and belongs to the rubber technical field, and the flame retardant rubber consists of the following raw materials by weight: 63-68 parts of styrene-butadiene rubber, 16-19 parts of natural rubber, 3-7 parts of magnesium chloride, 2-4 parts of stearic acid, 21-23 parts of carbon black, 12-14 parts of chlorinated paraffin, 3-5 parts of antimony trioxide, 1-3 parts of zinc borate, 2-5 parts of aluminum hydroxide and 3-8 parts of clay. The flame retardant rubber is added with the natural rubber, has the good performance of the natural rubber, and improves the shortcoming of single rubber; the flame retardant rubber uses the antimony trioxide, the aluminum hydroxide, the clay and the like as flame retardants, when the flame retardant rubber is heated, crystal water is released, heat is absorbed or thermal conductivity is improved, when in burning, the flame may be diminished, and the flame retardant rubber has good flame retardant performance.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to 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. [0003] Therefore, when the fire burns, the rubber inevitably burns too. The so-called flame retardant refers to the ability of rubber to delay the ignition time, reduce the speed of flame propagation and quickly extinguish itself after leaving the fire source. Generally, it is expressed by the oxygen index, the higher the oxygen index...
