Phenyl silicone rubber nano composite material and preparation method of same

Abstract

The invention discloses a phenyl silicone rubber nano composite material and a preparation method of same. The composite material is composed of, by mass, 100 parts of phenyl silicone rubber, 6-12 parts of modified nano-filler, 6-12 parts of a catalyst, 12-16 parts of a curing agent, 1-3 parts of a coupling agent, 1-5 parts of carbon fibers, and 1-3 parts of peanut shell powder. The preparation method includes the steps of primary mixing, secondary mixing and a curing reaction. The composite material has high-temperature resistant, low-temperature resistant and anti-impact effects, has elastic effect under a thinner condition, and is free of pulverization even after long time use.

Description

Technical field [0001] The invention relates to a phenyl silicone rubber nano composite material and a preparation method thereof. Background technique [0002] With the occurrence of the rubber industry, sealing rings are widely used, rubber seals occupy a very important position in the development of the national economy, and the creation of rubber seals has maintained a double-digit growth. [0003] With the improvement of the product technology level of my country's rubber and plastic seal manufacturing industry, the transfer of the world's processing and manufacturing industry to China and the effect of price leverage, the level of China's export of rubber and plastic seals has increased in recent years, and some products with higher technical content Has entered the international market. This situation has brought great development opportunities to domestic rubber and plastic seal manufacturers. [0004] The rapid economic development has brought about an increase in fixed ass...

AI Technical Summary

Problems solved by technology

[0006] 1. It is easy to age in the air and becomes sticky when heated. Although many manufacturers will add some anti-aging agents to the preparation of rubber materials, although it can increase the service life, it cannot fundamentally solve the aging problem.

[0007] 2. Low pressure resistance and easy deformation. Although natural rubber has high elasticity, its wear resistance is average and its aging resistance is low.

[0008] 3. Most of the rubber materials, whether it is natural rubber or synthetic rubber, need to add a certain amount of fillers to ensure the wear, elongation, hardness, tensile strength, and tear strength of rubber products. Hoarfrost, and the product is easily crushed
