Rubber liner plate with layer structure and preparation method of rubber liner plate

Abstract

The invention relates to a wear-resistant and erosion-resistant rubber liner plate with a layer structure and a preparation method of the rubber liner plate and belongs to rubber materials in the field of polymer materials. The rubber liner plate is formed by hot curing adhesion of a rubber substrate and surface wear-resistant rubber, wherein the surface wear-resistant rubber uses aramid fiber glass fiber and chinlon fiber to constitute a framework, special corrosion-resistant rubber is taken as a base material, and silicon carbide micropowder or zirconium carbide micropowder, aluminum oxide micropowder, silicon oxide micropowder and elemental silicon micropowder are added as admixtures for preparation, so that when the rubber liner plate is applied as a lining material, the rubber liner plate integrates not only certain strength, wear resistance, erosion resistance and puncture resistance, but also certain resilience and flexibility; and compared with a conventional metal liner or a liner poured by an inorganic nonmetallic material, the rubber liner plate has the characteristics of light weight and easiness in mounting and replacement.

Description

technical field [0001] The invention relates to rubber materials in the field of polymer materials, in particular to a layered rubber liner 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 rubber is mainly the wear resistance when it is only...

Problems solved by technology

[0004] In order to solve the problem that the wear resistance and puncture resistance of the existing rubber materials cannot meet the needs when used as the lining material that needs to withstand the scouring force, the invention provides a layered rubber liner and its preparation method, sacrificing the rubber The partial elasticity of the material improves its wear resistance, erosion resistance and puncture resistance, and a layer of wear-resistant ceramic sheet is pasted on its surface, so that it can be widely used in some pipelines for conveying powder, corrosive liquid, industrial mortar, etc. Lining, or the lining material of wear-resistant grading cyclone
