Abstract

The invention discloses high-strength wear-resistant rubber. Comprising the following raw materials in parts by weight: 50-80 parts of butadiene styrene rubber, 20-30 parts of epoxidized phenyl silicone rubber, 5-10 parts of polyethylene glycol, 1-3 parts of an anti-aging agent, 1-3 parts of pentachlorothiophenol, 0.5-2 parts of graphene oxide, 5-9 parts of sodium lignin sulfonate, 3-12 parts of ascorbic acid, 8-15 parts of nano silicon dioxide, 3-8 parts of a silane coupling agent, 1-2 parts of a composite light stabilizer, 1-2 parts of stearic acid and 1-1.5 parts of sulfur. The invention also discloses a preparation method of the high-strength wear-resistant rubber. The preparation method comprises the following steps: step 1, preparing a modified graphene oxide dispersion liquid; step 2, preparing a pre-dispersed adhesive; step 3, plastifying and mixing; and step 4, extrusion forming and vulcanization. The high-strength wear-resistant rubber provided by the invention has high strength and good wear resistance, aging resistance and weather resistance.

Description

Technical field [0001] The present invention belongs to the field of rubber technology, specifically, relates to a high-strength wear-resistant rubber and a method of preparation thereof. Background [0002] Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce a large deformation under the action of a small external force, and can be restored to its original state after removing the external force. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, the molecular weight is often very large, greater than hundreds of thousands. It is precisely because of its strong plasticity that it can be processed by various processes (vulcanization, extrusion, extrusion, blow molding, etc.) into various shapes and functions required, and has been widely used in various fields of life, production, and science and technology. [0003] Due to the continuous expansion of the application ...
