With the continuous development of modern industry, high-temperature silicone rubber (HTV), as an important high-performance rubber material, has received increasing attention and application. As an important preparation process, HTV blended silicone rubber has become one of the research hotspots. This article will introduce the preparation process and performance analysis of HTV blended silicone rubber.

The type and dosage of fillers, processing aids, and crosslinking agents are important factors affecting the performance of HTV blended silicone rubber during the preparation process. Fillers can alter the hardness, density, tear resistance, and other properties of silicone rubber, while processing aids can alter the viscosity, flowability, and processing properties of rubber blends. The type and dosage of crosslinking agent will affect the degree of crosslinking and mechanical properties of the mixed rubber.

In the preparation process of HTV blended silicone rubber, traditional mechanical mixing and heating mixing are two commonly used methods. Mechanical mixing is the use of a mixer to mix various components evenly, while heating mixing involves heat treatment of the mixed rubber at high temperatures. Research has shown that mechanical mixing and heating mixing can complement each other and improve the performance of the mixed rubber.

In the performance analysis of HTV blended silicone rubber, hardness, tensile strength, and elongation at break are commonly used performance indicators. Among them, hardness can reflect the hardness and elasticity of silicone rubber, tensile strength can reflect the tensile strength and tear resistance of silicone rubber, and elongation at break can reflect the ductility and flexibility of silicone rubber.

In addition to the above indicators, HTV blended silicone rubber also has other important performance characteristics. For example, HTV blended silicone rubber has good high temperature resistance and chemical stability, and can maintain good performance in high temperature, acid and alkali and other harsh environments.
