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:
The present invention relates to rubber manufacturing technology field, be specifically related to a kind of non-sulfur-modified neoprene formula, the rubber composite adopting this formula to prepare has excellent acid-proof alkaline.
Background technology:
Chloroprene rubber is the synthetic rubber that raw material obtains by chloroprene, and polychloroprene rubber for general purpose is divided into sulphur tune type and non-two kinds, sulphur tune type, and can not need promotor during sulfur-modified neoprene sulfuration, non-sulfur-modified neoprene need coordinate promotor.Chloroprene rubber has good physical and mechanical properties, oil resistant, acid and alkali-resistance, and the performances such as chemical-resistant reagent are widely used in rubber roll, sebific duct, the fields such as conveying belt.Particularly in Steel Wire Products Industry, need to carry out acid etching to metallic surface and reach clean, sub-light requirement, rubber roller for industry needs to be immersed in acid solution or alkali lye etc. for a long time to be had in corrosive medium, so higher to rubber item performance requriements.The present invention in formula, introduce laminated structure Graphene and carbon black also uses reinforcement chloroprene rubber, Graphene adds and not only realizes reinforcement to chloroprene rubber, laminated structure filler effectively prevents acid-alkali medium to the erosion of chloroprene rubber internal structure simultaneously, thus preparation high-performance acid and alkali-resistance chloroprene rubber matrix material, meet the performance requriements of current Industrial products to neoprene neoprene.The present invention not only solves performance requriements under chloroprene rubber normal service condition, and gives the acid and alkali-resistance dielectric behavior of chloroprene rubber excellence, has superior performance conservation rate, thus effectively extends neoprene neoprene work-ing life, realizes larger industrial value.
Summary of the invention:
The object of the invention is to provide a kind of acid and alkali-resistance Chloroprene rubber formula, solve the problem of chloroprene rubber acid-alkali-corrosive-resisting difference, the chloroprene rubber matrix material adopting this formula to prepare has higher-strength, superior abrasion resistance, acid and alkali-resistance dielectric behavior, constant product quality, long service life feature.Because current Graphene cost is higher, the consumption of the present invention to Graphene is optimized, and in Graphene amount ranges of the present invention, chloroprene rubber matrix material has excellent over-all properties.
