Layered wear-erosion resistant rubber lining plate and preparation method thereof

Abstract

The invention relate to a layered wear-erosion resistant rubber lining plate and a preparation method thereof, belonging to rubber materials in the field of polymer materials. The rubber lining plate is formed by splicing a rubber substrate with a surface wear resistant rubber through heat curing. The rubber lining plate is prepared from a surface wear resistant rubber, a special anticorrosion rubber and additives, wherein the surface wear resistant rubber serves as a framework and comprises aramid glass fiber and polyamide fiber, the special anticorrosion rubber servers as a substrate, and the additives comprise silicon carbide micropowder or zirconium carbide micropowder, aluminium oxide micropowder, silicon oxide micropowder and elemental silicon micropowder. The rubber lining plate can be used as a lining material, has a certain strength, abrasion resistance, erosion resistance and puncture resistance and also has a certain resilience and flexibility. Compared with the conventional metal linings or inorganic nonmetallic material poured linings, the rubber lining plate provided by the invention has the characteristics of light weight and easiness for installation and replacement.

Description

technical field [0001] The invention relates to rubber materials in the field of polymer materials, in particular to a wear-resistant and erosion-resistant rubber liner with a layer structure and a preparation method thereof. Background technique [0002] Rubber is an elastic polymer that can be obtained from the sap of some plants (natural rubber) or man-made (synthetic rubber). Because there are many types of synthetic rubber, different types of rubber have different properties. For example, butadiene rubber has excellent cold resistance, abrasion resistance, elasticity and aging resistance, but poor tear resistance and wet skid resistance; isoprene rubber, like natural rubber, has good elasticity and Wear resistance, excellent heat resistance and good chemical stability; ethylene propylene rubber has good chemical stability, and its wear resistance, elasticity, oil resistance and styrene-butadiene rubber are close. [0003] However, the so-called good wear resistance of ...
