Description
Technical Field
The invention belongs to the field of cable material preparation, and relates to an oil-resistant solvent-resistant rubber composite material, a preparation method thereof and application thereof in cables.
Background
JEM is one of motor lead wires and meets the requirements of JB/T6213 and 2006 standards. The rubber has high aging resistance, and needs to pass a solvent resistance test, an impregnating varnish resistance test and a thermal effect test, the conventional rubber of JEM is CPE, the conventional rubber has excellent weather resistance and aging resistance, the conventional rubber has an application history of more than 10 years in the cable industry, and the conventional rubber is mature relative to the conventional rubber, but the aging resistance and the solvent resistance of the conventional rubber are inferior to those of ECO rubber.
The ECO rubber is a polymer formed by homopolymerization of epoxy chloropropane or copolymerization of epoxy chloropropane and ethylene oxide, but the oil resistance and the solvent resistance of the ECO rubber in the application of the cable material at present need to be further improved.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an oil-resistant and solvent-resistant rubber composite material which is simple in preparation method and excellent in physical properties.
The purpose of the invention can be realized by the following technical scheme: the oil-resistant and solvent-resistant rubber composite material comprises the following raw materials in parts by weight: 80-100 parts of ternary polymerization type epichlorohydrin rubber, 1-20 parts of nitrile rubber, 10-30 parts of reinforcing agent, 20-40 parts of eukeite, 5-30 parts of barium sulfate powder, 3-5 parts of magnesium oxide, 5-10 parts of calcium carbonate, 1-5 parts of anti-aging agent and 0.5-2 parts of vulcanizing agent.
In the oil-resistant solvent-resistant rubber composite material, the chlorine content of the terpolymer epichlorohydrin rubber is 24-27%, and the Mooney viscosity ML1+4 100℃Is 55-85. The invention needs to control the chlorine content in the terpolymer epichlorohydrin rubber, because the higher the chlorine content is, the better the oil resistance and solvent resistance of the composite material is, but the too high chlorine content can cause the processing performance to be poor, so the Mooney viscosity needs to be controlled, the lower the Mooney viscosity is, the better the processing performance of the composite material is, and the Mooney viscosity is controlled in order to realize the excellent processing performance.
In the oil-resistant and solvent-resistant rubber composite material, the content of ACN in the nitrile rubber is 33-43%, and the Mooney viscosity ML1+4 100℃Is 40-70.

In the oil-resistant and solvent-resistant rubber composite material, the particle size of barium sulfate powder is 2-5 μm. The smaller the particle size of the barium sulfate powder, the better the mechanical property of the rubber compound, but the lower the uniformity of the mixing, the invention reasonably controls the particle size of the barium sulfate powder, and realizes the balance of the performance requirement of the rubber composite material and the processing technology.
In the oil-resistant and solvent-resistant rubber composite material, the vulcanizing agent is 2, 4, 6-trithiol thiotriazine. The 2, 4, 6-trithiolthiotriazine is selected as the vulcanizing agent in the invention because it has good extraction resistance in the solvent, which can further enhance the solvent resistance of the rubber composite material.
In the oil-resistant and solvent-resistant rubber composite material, the anti-aging agent is one or more of NBC, RD, ODA and 4010 NA.
The invention also provides a preparation method of the oil-resistant and solvent-resistant rubber composite material, which comprises the following steps:

s3, placing the internally mixed raw materials into an open mill, and adding a vulcanizing agent for open milling treatment to obtain a rubber compound;
and S4, conveying the mixed rubber to a double-stage extruder for pressing to obtain the composite rubber material.
In the preparation method of the oil-resistant and solvent-resistant rubber composite material, the mixing and banburying temperature of the step S2 is 80-100 ℃, and the time is 9-15 min.
In the preparation method of the oil-resistant and solvent-resistant rubber composite material, the open milling treatment temperature of the step S3 is 50-60 ℃ and the time is 5-10 min.

Compared with the prior art, the invention has the following beneficial effects: according to the invention, the nitrile rubber, the activated nano silica and the barium sulfate powder are added on the basis of the terpolymer epichlorohydrin rubber, so that the oil resistance and the solvent resistance of the rubber composite material are greatly improved while good physical properties are ensured.
