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
the invention belongs to field of rubber technology, specifically a kind of flame retardant rubber.
Background technology
Usually, people are that rubber does not burn under general combustion conditions for the understanding of flame retardant rubber, and this is a kind of misunderstanding in fact.Because there is not so-called general combustion conditions.Polymeric articles can not stop burning with some form, and what can accomplish is only change its combustion system.If polymkeric substance is placed in the sufficiently long time, burn under sufficiently high temperature and abundant Oxygen Condition, then any measures for the prevention of fire will be all invalid.
Therefore, after fire blazes up, rubber inevitably also will burn.So-called fire-retardantly refers to that rubber delays the time of catching fire, reduce flame propagation velocity and can the ability of self-extinguish rapidly after leaving burning things which may cause a fire disaster.Generally, it represents with oxygen index, and oxygen index is higher, and flame retardant properties is better.It has been generally acknowledged that, oxygen index is self-extinguishing more than 27%; Be inflammable material lower than this numerical value; The higher person of oxygen index is then nonflammable material.If polyacrylic oxygen index is 17%, be incendivity in atmosphere.The task of rubber compounding worker is confined to change ignition condition, the speed of propagation of flame of slowing down and the impetus of suppression intensity of a fire growth.
Therefore, effective method of fire protection is exactly that the oxygen broken off needed for burning supplies or isolation thermal source, and the principle of the latter is: discharge crystal water when having a kind of material to be heated, absorb heat or improve heat conductivity, then also can play fire retardation, therefore, when there is burning, flame will weaken.
Summary of the invention
The object of the present invention is to provide a kind of flame-retardant chloroprene rubber.
Object of the present invention can be achieved through the following technical solutions:
Flame retardant rubber, this flame retardant rubber comprises following raw material: styrene-butadiene rubber(SBR) 63-68 part, natural rubber 16-19 part, magnesium chloride 3-7 part, stearic acid 2-4 part, carbon black 21-23 part, clorafin 12-14 part, antimonous oxide 3-5 part, zinc borate 1-3 part, aluminium hydroxide 2-5 part, potter's clay 3-8 part.
Preferably, this rubber comprises following raw material: 65 parts, styrene-butadiene rubber(SBR), natural rubber 18 parts, 5 parts, magnesium chloride, stearic acid 3 parts, carbon black 22 parts, clorafin 13 parts, antimonous oxide 4 parts, zinc borate 2 parts, 4 parts, aluminium hydroxide, 5 parts, potter's clay.
Beneficial effect of the present invention: the present invention is added with natural rubber, has the premium properties of natural rubber, improves the shortcoming of single rubber; The present invention for fire retardant, discharges crystal water with antimonous oxide, aluminium hydroxide, potter's clay etc. when being heated, absorb heat or improve heat conductivity, when there is burning, flame will weaken, and has good flame retardant properties.
