Problems solved by technology

The rubber products in these complete equipment cannot emit strong or obvious unpleasant odors in daily use, making users feel uncomfortable. It is also necessary to consider the different indoor and outdoor use conditions, and the cold season is different from the hot season. Affected by factors such as temperature and humidity environment, rubber products should maintain a small odor and not continuously emit unpleasant odors during long-term use

Abstract

The invention discloses a low-odor rubber product, comprising, ethylene propylene diene monomer rubber, modified neoprene, carbon black N550, an activator, plasticizer 2240, a filling agent, zinc oxide, dispersant 935P, polyethylene glycol, stearic acid, sulfur, a promoter, and odor absorber RT500. Through the coordination of the modified neoprene with ethylene propylene diene monomer rubber, carbon black, odor absorbent RT500, zinc oxide, activator and the like, the low-odor rubber product has no fouling odor, never produces stimulating odor during long-term usage, and also has the good properties of weatherability, fire resistance, ozone resistance, heat resistance, oxidative pyrolysis resistance, oil resistance, solvent resistance, aging resistance, and shock resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a low-odor rubber product. Background technique [0002] A large number of rubber products are used in household appliances and automobiles. With the gradual improvement of people's quality of life, the satisfaction of the functionality of household appliances and automobiles has risen to the satisfaction of comfort, and the requirements for the whole machine are also increasing. come higher. The rubber products in these complete equipment cannot emit strong or obvious unpleasant odors in daily use, making users feel uncomfortable. It is also necessary to consider the different indoor and outdoor use conditions, and the cold season is different from the hot season. Affected by factors such as temperature and humidity environment, rubber products should maintain a small odor and not continuously emit unpleasant odors during long-term use. Contents of the invention [0003] Base...
