Problems solved by technology

Among them, rubber has poor temperature resistance and is easy to age, so it is not suitable for high temperature and long-term use; plastic and synthetic materials have poor elasticity and high precipitates, and the service life of hoses is short and cannot be used in high-demand industries such as food and medical treatment; although traditional silicone rubber It has the excellent and unique characteristics of silicone rubber, but its wear resistance and pressure bearing capacity are poor, resulting in a short service life of the hose. If a peroxide vulcanized hose is used, it will stick and fail to transport fluid

Abstract

The invention relates to the field of organic silicon high-polymer materials, in particular to long-life silicon rubber for peristaltic pump pipes and a preparation method of the long-life silicon rubber. The silicon rubber is prepared from raw materials in parts by mass as follows: 50-150 parts of methyl vinyl polysiloxane, 40-60 parts of reinforcing filler, 1-12 parts of a structurized control agent, 0.1-1.0 part of a hydrosilylation catalyst, 0.5-2 parts of a cross-linking agent, 0.05-0.2 parts of an inhibitor and 0.1-0.6 parts of a release agent, wherein the methyl vinyl polysiloxane is a mixture formed by mixing vinyl-terminated methyl vinyl polysiloxane with all side chains being methyl groups and methyl-terminated methyl vinyl polysiloxane with side chains containing vinyl groups in any mass ratio. The silicon rubber for the peristaltic pump pipes has excellent weather resistance, temperature resistance and biocompatibility of silicon rubber, and the molded silicon rubber pipes have very long service life and are good in wear resistance and pressure bearing capability.

Description

technical field [0001] The invention relates to the field of organosilicon polymer materials, in particular to a high-life silicone rubber for peristaltic pump tubes and a preparation method thereof. Background technique [0002] The peristaltic pump hose is an important accessory of the peristaltic pump, mainly used to transport the mixture of liquid, gas, liquid and gas, and liquid and solid. Existing hose materials mainly include rubber, plastics, synthetic materials, silicone rubber and the like. Among them, rubber has poor temperature resistance and is easy to age, so it is not suitable for high temperature and long-term use; plastic and synthetic materials have poor elasticity and high precipitates, and the service life of hoses is short and cannot be used in high-demand industries such as food and medical treatment; although traditional silicone rubber It has the excellent and unique characteristics of silicone rubber, but its wear resistance and pressure bearing cap...
