Abstract

The invention relates to a rubber assembly material for a bellows drainpipe of a roller washing machine and a manufacturing process thereof, and the rubber assembly comprises the main raw materials ofethylene propylene diene monomer (EPDM), pot clay, NKL-9, paraffin hydrocarbon oil and the like. The bellows drainpipe product treated by the process has fine soap solution resistant performance, copper ion resistant performance, vapor resistant performance and good 2500V-resistant insulation resistance performance, thus ensuring nice tightness and safety durability performance. The invention improves soap solution resistance and vapor resistance for the products, solves the technical problems such as copper ion discoloration resistance, punctured 2500V-resistant insulation resistance products and the like. The products conform to environmental directive requirement of EU, provide a safe and reliable clothes-washing environment for consumers, have fine vibration reducing performance, andprovides powerful guarantee for the roller washing machine to develop toward mute direction. The successful development of the products replaces the imported medium-high end roller washing machine bellows drainpipes, realizes products localization and improves the competitive strength for the home-made roller washing machines in the market.

Description

technical field [0001] The invention relates to a rubber component material for a drum washing machine, in particular to a rubber component material for a drain bellows on a drum washing machine and a manufacturing process thereof. Background technique [0002] The door seal is used on the drum washing machine. As one of the key components of the washing machine, it is installed between the washing chamber of the washing machine and the door of the washing machine through a clamp. The main function is to prevent water leakage and play a sealing role. [0003] From the perspective of product development trend, with the gradual improvement of people's living standards, people have higher and higher requirements for the use of consumer goods. Compared with the previous pulsator washing machines, drum washing machines can better meet the needs of current consumers in use. The sales of front-loading washing machines have shown a continuous growth trend in recent years. According ...
