Embodiment Construction

[0034] The invention provides a raw material for preparing automobile cushion block rubber, which comprises the following components measured in parts by mass: 70-90 parts of Lanxess 9650 EPDM rubber; 10-30 parts of HS-60 high styrene rubber 4-6 parts of active zinc oxide; 1-3 parts of stearic acid; 1-3 parts of anti-aging agent RD; 1-3 parts of anti-aging agent 4010NA; 0.5-2 parts of microcrystalline wax; 1-3 parts of oleic acid amide; 20-35 parts of Cabot N220 carbon black; 25-40 parts of Cabot N550 carbon black; 0.8-1.4 parts of sulfur; 1.2-1.8 parts of vulcanizing agent BZ; 0.8-1.2 parts of accelerator M; 0.3-0.5 parts of accelerator TT share.

[0035] Among them, the grade of EPDM rubber is LANXESS 9650; the model of high styrene rubber is HS-60. LANXESS 9650 EPDM rubber has the advantages of high tensile strength and high filling, and does not contain inner oil, which is suitable for the production of high hardness rubber; HS-60 high styrene rubber has both the elastici...

Abstract

The invention belongs to the field of rubber material, and especially relates to an automobile buffer cushion block rubber preparation raw material and a preparation method thereof; the automobile buffer cushion block rubber preparation raw material includes, in parts by weight, 100 parts of a main material, 45-75 parts of carbon black, 3.1-4.9 parts of a vulcanization system, 1-3 parts of a plasticizing activity increasing agent, 4-6 parts of a reinforcement agent, 2-6 parts of an anti-aging agent, 1-3 parts of an internal lubricant, and 5-10 parts of naphthenic oil, wherein the main material includes 70-90 parts of ethylene-propylene-diene monomer, and 10-30 parts of high styrene rubber; the carbon black includes 20-35 parts of carbon black N220 and 25-40 parts of carbon black N550. With adoption of the special raw rubber system, a rubber material with high hardness and good fluidity is prepared; with adoption of the special anti-thermal oxygen aging system, the shortage of the anti-thermal oxygen aging performance of rubber is improved; with adoption of the special raw rubber material and the anti-ozone system, the ozone destruction resistant ability of the rubber is increased; and with adoption of the internal lubrication system, the frictional resistance of the rubber surface is reduced.

Description

technical field [0001] The invention belongs to the field of rubber materials, and in particular relates to a raw material for preparing automobile buffer block rubber and a preparation method thereof. Background technique [0002] Automobile cushion blocks are mainly to withstand the static extrusion, dynamic impact and friction of auto parts. Generally, automobile buffer pads require suitable hardness, excellent hot air aging resistance and weather resistance, and low frictional resistance. [0003] There are many materials for the preparation of existing automobile spacers. For example, the invention patent of patent application number CN201511030557.0 and application name "Polyurethane composition for automobile sunroof cushion block and its preparation method" discloses "a kind of A polyurethane composition for a cushion block and a preparation method thereof belong to the technical field of polyurethane applications. The polyurethane composition for an automobile sunr...
