Abstract

The invention discloses a preparation method of an automobile water pipe rubber material without toluene spray. The preparation method comprises a formula and a preparation process. EPDM (ethylene propylene diene monomer) rubber is utilized, N,N'-1,3-phenylene bismaleimide and modified dimethylacrylic metal salt are added to the formula as cross-linking agents, so that adhesion between the rubbermaterial and tire cords as well as between the rubber materials is increased, and peel strength of an automobile water pipe product is improved; under supporting of the technical scheme of the corresponding preparation technology, the automobile water pipe rubber material without toluene spray is prepared, therefore, the automobile water pipe product without toluene spray is free of toluene, meetsthe NESD5806 standard and the ELV instruction and meets the ever-increasing environmental requirement of the automobile industry for rubber products.

Description

technical field [0001] The invention relates to the preparation of a rubber material, in particular to a method for preparing an automobile water pipe rubber material free from spraying toluene, which is used for making automobile cooling water pipe products. Background technique [0002] Automobile cooling water pipe products are multi-layer composite rubber hose products, referred to as automobile water pipes. During the production of automobile water pipes, in order to increase the adhesion strength between rubber and cord, rubber and rubber, it is necessary to spray toluene between the composite layers. , so toluene will remain in the automobile water pipe; [0003] Since toluene is a flammable, explosive and high-risk chemical, spraying toluene will pollute the environment, and long-term human exposure to toluene is harmful to health. With the enhancement of environmental protection awareness, the Nissan NESD5806 standard and the ELV directive require automobile water p...
