Abstract
The invention discloses conductive rubber with flame retardation. The conductive rubber is characterized by being prepared from the raw materials in parts by weight: 60-80 parts of ethylene-propylene-diene rubber, 20-30 parts of silicone rubber, 15-30 parts of carbon fibers, 5-20 parts of carbon black, 1-10 parts of graphite, 25-40 parts of flame retardant, 1-3 parts of vulcanizing agent and 2-8 parts of coupling agent. According to the conductive rubber with flame retardation disclosed by the invention, organic flame retardant and inorganic retardant are matched for use, so that the adding amount is less, the flame retardation is excellent and poisonous and toxic gases are not generated. Moreover, the conductive rubber is good in mechanical performance, good in heat resistance and mechanical strength and capable of improving wear resistance.
Description
?
Technical field
The invention belongs to field of rubber materials, specifically is a kind of conductive rubber with flame retardant properties.
Background technology
A kind of as in the conductive polymer composites of conductive rubber, be to be that matrix adds that conductive filler material makes with the rubber elastomer, the elasticity that had both kept base rubber, the electroconductibility that has conductive filler material again, because material can in very large range be regulated electricity and the mechanical property of material according to service requirements, advantages such as quality is light, easily machine-shaping, cost are low, technology maturation, obtained in recent years developing rapidly, become a kind of new function material, be widely used in space flight, aircraft manufacturing and machinery manufacturing industry, medical science, electric and electronic industry.In the last few years, along with the development of electronic industry, electromagnetic wave shielding sealing material demand also constantly enlarged.Mostly conductive rubber in the market is common non-flame retardant rating, especially is the conductive rubber of filler with the nickel bag graphite, and the high flame retardant grade is few especially.So at some to fire-retardant demanding occasion, the conductive rubber of common grade, its application has been subjected to certain restriction.
Summary of the invention
The object of the present invention is to provide the good conductive rubber of a kind of flame retardant properties.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of conductive rubber with flame retardant properties, it is characterized in that, comprise the raw material of following parts by weight: terpolymer EP rubber 60-80 part, silicon rubber 20-30 part, carbon fiber 15-30 part, carbon black 5-20 part, graphite 1-10 part, fire retardant 25-40 part, vulcanizing agent 1-3 part, coupling agent 2-8 part.
Fire retardant of the present invention comprises organic fire-retardant and inorganic combustion inhibitor.
Vulcanizing agent of the present invention is boron phosphide BP, and described coupling agent is titanate coupling agent.
Described organic fire-retardant is phosphoric acid ester, and described inorganic combustion inhibitor is magnesium hydroxide or aluminium hydroxide.
Beneficial effect of the present invention: the present invention utilizes organic fire-retardant and inorganic combustion inhibitor to be used, addition is few, flame retardant properties excellence, and do not produce toxic and harmful, the mechanical property of this conductive rubber is good, high thermal resistance, physical strength are good, wear resisting property is improved.
