Abstract

The invention discloses a preparation process of a rubber composite material for an oil-resistant sealing rubber strip. The invention relates to the field of sealing rubber strips. The main materialscomprise the following components in parts by weight:90-110 parts of NBR, 3.5-4.5 parts of an active agent, 0.38-0.42 part of stearic acid SA, 56-64 parts of a filler, 0.48-0.52 part of sulfur, 0.7-0.9 part of an accelerant, 5-7 parts of a cold-resistant plasticizer DOA, 4-5 parts of an anti-aging agent and 2.3-2.7 parts of a vulcanizing agent DCP. The preparation method comprises the following specific preparation steps: S1, mixing; s2, vulcanization sample preparation. According to the invention, by means of the NBR, active agent, stearic acid SA, filling material, sulfur, promoter, cold-resistant plasticizer DOA, anti-aging agent and vulcanizing agent DCP, a mixing process is adopted, optimal processing parameters can be obtained through vulcanization sample preparation, the prepared sealing rubber strip has the characteristics of excellent corrosion resistance, aging resistance, cold resistance, oil corrosion resistance and the like, the sealing rubber strip is also suitable for mass production, and the product quality and the yield can be well guaranteed.

Description

technical field [0001] The invention relates to the technical field of sealing rubber strips, and more specifically, the invention relates to a preparation process of a rubber composite material for oil-resistant sealing rubber strips. Background technique [0002] Rubber seal strips are rubber strips produced from rubber for product sealing. Mainly used in the fields of automobiles, machinery, doors and windows, etc., it can prevent the leakage or intrusion of internal and external media (rainwater, air, sand, etc.), and can prevent or reduce damage caused by mechanical vibration and impact, so as to achieve sealing, Elastic strip or rod material for sound insulation, heat insulation and shock absorption. [0003] However, when the existing sealing strips are in use, they generally have good sealing performance, but when encountering oil stains (petroleum car wax), they will quickly cause corrosion of the sealing strips, resulting in poor sealing effects.
