Embodiment 1

[0066] The invention discloses an anti-aging rubber sealing ring material and a preparation method thereof. The specific steps are as follows:

[0067] Step 1: Weigh the raw materials in parts by weight: the weighing of the materials is carried out in the following proportions: 80 parts of styrene-butadiene rubber, 20 parts of acrylate rubber, 15 parts of neoprene rubber, 25 parts of nano-ceramic clay, 10 parts of polyurethane rubber, 8 parts of lactone, 15 parts of reinforcing filler, 4 parts of nano silica, 5 parts of quartz fiber, 8 parts of nano titanium dioxide, 2 parts of composite antioxidant, 4 parts of vulcanizing agent, 2.5 parts of auxiliary vulcanizing agent, 4 parts of bauxite powder , 10 parts of plasticizer;

[0068] Step 2: Mixing treatment of raw materials: Add styrene-butadiene rubber and acrylate rubber into the internal mixer, and plasticize on the internal mixer. When the thickness of the plasticized rubber reaches 1mm, add polycaprolactone evenly, and at ...

Abstract

The invention provides an anti-aging rubber sealing ring material and a preparation method thereof, and belongs to the technical field of rubber sealing materials. The preparation method of the anti-aging rubber sealing ring material comprises the following steps of weighing of raw materials by weight, raw material mixing, primary mixed material re-treatment, secondary rubber compound re-treatment, die assembly and vulcanization molding, edge cutting and trimming, and quality inspection and classification. The anti-aging rubber sealing ring material and the preparation method thereof have theadvantages that bauxite powder is dispersed in a raw material network structure, so that the wear resistance of a rubber gasket is improved; due to the use of a plasticizer, the vitrification temperature of rubber is reduced, the plasticity and fluidity of the rubber are enhanced, and the hardness and tensile stress of the rubber are reduced; nano silicon dioxide and quartz fiber are added, so that the pressure resistance, anti-aging performance and corrosion resistance of the sealing ring material are enhanced, and the phenomena of overflow and leakage are effectively prevented; the preparation process is simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of rubber sealing materials, and particularly relates to an anti-aging rubber sealing ring material and a preparation method thereof. Background technique [0002] In industrial production, pipeline connections are generally connected by flanges, and rubber gaskets are added between flanges for sealing. Some containers, equipment, etc. use rubber gaskets as sealing gaskets. Most of these rubber gaskets and sealing gaskets are made of natural rubber, Styrene-butadiene rubber, etc. [0003] Rubber seals are a kind of general basic element in sealing devices. Rubber seals are a type of rubber products widely used in sealing technology. They are widely used because of their small elastic modulus, high elongation, and air permeability. For installation on various mechanical equipment. In the working environment, the lubrication system of mechanical equipment contains acid and alkali components, which easily pen...
