Abstract

The invention relates to a rubber synchronous belt with safe polycyclic aromatic hydrocarbon content, which comprises the following components: chloroprene rubber, butadiene rubber, reinforcing agent,anti-aging agent, accelerating agent, zinc oxide, magnesium oxide, stearic acid, processing oil and the like. The rubber synchronous belt is prepared by the following steps: firstly, forming a belt colloid by a rubber plasticating and mixing process; secondly, calendering the belt colloid into flakes; and performing the steps of molding, sulfurization, demoulding, back grinding, cutting, checkingand the like to obtain the rubber synchronous belt, wherein the polycyclic aromatic hydrocarbon (PAHs) content refers to a ZEK 01-08 standard and is analyzed and detected by adopting a GC-MS method,and the result is 4.2 ppm which proves that the rubber synchronous belt is completely in accordance with UE environmental protection requirements and is environmentally-friendly. The preparation process of the rubber synchronous belt is simple and is convenient to maintain and replace. Thus, the rubber synchronous belt is expected to be widely applied to the aspects of automobiles, chemical fibers, textile machinery, cigarette machines, paper making, printing machines, the chemical industry, the light industry, grains, foods, mechanisms, mining, metallurgy, steel machinery, office equipment, medical devices, communications equipment and various precision machine tools, precision instruments and the like.

Description

technical field [0001] The invention relates to a rubber synchronous belt with safe content of polycyclic aromatic hydrocarbons. Background technique [0002] Polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons, PAHs) are a class of hydrocarbons formed by two or more benzene rings bonded to each other. A class of hazardous substances produced under certain conditions. It usually exists in petrochemical products, rubber, plastic, lubricating oil, anti-rust oil, incompletely burned organic compounds and other substances, and is one of the important carcinogens in the environment. In addition, human activities such as automobile exhaust gas, residential heating system, waste combustion, oil thermal cracking, and factory boiler combustion emissions are also the main sources of PAHs. Since mineral oil and coal tar are often used as plasticizers in the production of plastic and rubber industries, if some mineral oil and coal tar contaminated by PAHs are used as pl...
