A kind of acid and alkali resistant neoprene rubber

Abstract

The invention discloses acid and alkali resisting chloroprene rubber with excellent acid and alkali resistance and relates to the technical field of rubber manufacturing. The chloroprene rubber is widely applied because of good mechanical performance, oil resistance, and acid and alkali resistance. Traditional chloroprene rubber strengthened by a filler is poor in acid and alkali resistance. According to the acid and alkali resisting chloroprene rubber, graphene with a large lamellar structure, carbon black and white carbon black are introduced into the formula to strengthen chloroprene rubber, introduction of the graphene strengthens the chloroprene rubber, and a filler with a lamellar structure effectively protects the inner structure of the chloroprene rubber from being corroded by acid and alkali media, thus preparing a high-performance acid and alkali resisting chloroprene rubber composite material and meeting performance requirements of industrial products on chloroprene rubber products. Performance requirements of chloroprene rubber under conventional using conditions are met, the chloroprene rubber is endowed with excellent mechanical performance and acid and alkali resistance, and the performance conservation percentage is high, thus effectively prolonging the service lifetime of chloroprene rubber products, and achieving higher industrial and social benefits.

Description

Technical field: [0001] The invention relates to the technical field of rubber manufacturing, in particular to a non-sulfur adjusted chloroprene rubber formula, and the rubber composite material prepared by using the formula has excellent acid and alkali resistance. Background technique: [0002] Neoprene is a synthetic rubber made from chloroprene. General-purpose neoprene is divided into two types: sulfur-modified and non-sulfur-modified. Adjustable neoprene rubber needs to be combined with accelerators. Neoprene has good physical and mechanical properties, oil resistance, acid and alkali resistance, chemical reagent resistance and other properties, and is widely used in rubber rollers, rubber hoses, conveyor belts and other fields. Especially in the metal product industry, it is necessary to acid-etch the metal surface to achieve clean and matte requirements. Industrial rubber rollers need to be soaked in corrosive media such as acid or lye for a long time, so the perfor...
