Abstract

A rubber voice diaphragm is composed of main rubber, distortion improving agent, vulcanizing agent, accelerant, reinforcing filler, and other processing aids. The distortion improving agent is a substance with number-average molecular weight ranging from 1000 to 1000000, and structure of distortion improving agent has special chemical crosslinking points that participate in rubber vulcanization reaction. The special chemical crosslinking points are present in amount of 0.01% to 30% based on mass of distortion improving agent. The distortion improving agent is added in amount of 0.1% to 100% based on mass of main rubber. Frequency bands for improving distortion of distortion improving agent range from 0.1 HZ to 20000 Hz. In the rubber voice diaphragm provided in the present disclosure, a special distortion improving agent is selected, which solves the problems of molecular migration, poor reliability, a high modulus change rate, and poor rubber mechanical properties existing in traditional modified method.
