Abstract

The invention discloses a preparation method of a low-VOC (volatile organic compound) EPDM (ethylene-propylene-diene monomer) environment-friendly flame-retardant automobile interior rubber material,and belongs to the technical field of rubbers. The preparation method comprises the following steps: firstly, putting EPDM, carbon black, a reinforcing filler, a flame retardant, a softening plasticizer, an active agent and a deodorant into an internal mixer to obtain a first rubber compound; and adding the first rubber compound, a vulcanizing agent and an accelerant into an internal mixer to obtain the low-VOC EPDM environment-friendly flame-retardant automobile interior rubber. Mixing is carried out in two stages; at the mixing temperatures in each step, volatilization of harmful gas is prevented and smooth chemical reaction is guaranteed, and the prepared material has the characteristics of low VOC, no odor, environment friendliness and flame retardance, is suitable for automotive innerornaments, has extremely low volatile gas and odor in a use environment, does not pollute the environment in an automobile, and is harmless to human bodies and the environment.

Description

technical field [0001] The invention belongs to the technical field of rubber, and particularly relates to a production method of a low-VOC EPDM environment-friendly flame-retardant automobile interior material. Background technique [0002] EPDM is ethylene-propylene-diene rubber, which is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It contains unsaturated double bonds, so it has excellent aging resistance such as ozone resistance, heat resistance and weather resistance. [0003] Due to its good comprehensive properties, EPDM materials have been widely used in major automotive assembly systems, and are also more and more widely used in automotive interiors. As the society attaches great importance to human health and environmental protection, in addition to good mechanical properties, processing properties, weather resistance and scratch resistance, automotive interior materials must also have good low volatility, and the odor requirement...
