Abstract

The invention relates to the technical field of rubber materials, in particular to high-elasticity pressure-tight anti-collision rubber used for mechanical equipment. The rubber material is prepared from butadiene rubber, nitrile butadiene rubber, natural rubber, metal ceramic powder, an ethylene-vinyl acetate copolymer, organic silicone oil, an elastomer, N,N'-ethylene bis-stearamide, zinc oxide,a flexibilizer, a silane coupling agent and a stabilizer, wherein the metal ceramic powder is the powder prepared by compounding materials of aluminium oxide powder, titanium carbide, carbon black and the like, an SEBS elastomer or an SEPS elastomer is selected as the elastomer, the flexibilizer is polyester resin-grafted polyurethane, and the stabilizer is a sulfur-containing organic tin stabilizer or a compound lead salt stabilizer. The rubber has the advantages of excellent heat resistance and ageing resistance performance, good rebound resilience and outstanding pressure-tight performance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-elasticity and pressure-resistant anti-collision rubber for mechanical equipment. Background technique [0002] Natural rubber is made by coagulating and drying the latex that flows out from Hevea clover tree tapping. The finished product after processing is a material that is elastic, insulating, impermeable to water and air. It is mainly divided into two types of natural rubber and synthetic rubber. Natural rubber is processed after extracting gum from plants such as rubber trees and rubber grasses. Synthetic rubber is obtained by polymerization of various monomers. Common rubber on the market is divided into natural rubber, general rubber, styrene-butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, isoprene rubber, ethylene-propylene rubber, and neoprene. [0003] Rubber materials are widely used in industries such as transportation equipmen...
