Production process and equipment of methyl vinyl silicone rubber

Abstract

The invention discloses a production process and production equipment of methyl vinyl silicone rubber, which relate to a raw rubber polymerization process. The invention is characterized in that the production equipment of the methyl vinyl silicone rubber consists of a filter, a metering tank, a dehydrating kettle, a metering pump, a preheater, a polymerization cylinder, a low molecule removing device, a nitrogen generator, a vacuum pump, a discharging machine and the like. The filter is connected with the dehydrating kettle through the metering tank, the dehydrating kettle is connected with the preheater through the metering pump; the preheater is connected with the polymerization cylinder by a pipe; the polymerization cylinder is connected with the low molecule removing device, and the low molecule removing device is connected with the discharging machine by a pipe. The production process of the methyl vinyl silicone rubber comprises: metering dimethyl carbonate (DMC) by the filter; and filling the DMC into the dehydrating kettle, adding alkaline cement, end-capping agent and the like in mixing amount, delivering the mixture to the polymerization kettle through a preheater and a feeding pump, performing polymerization at a certain temperature, filling the reaction solution in the low molecule removing device to remove low molecules under vacuum and filling into the discharging machine to generate raw robber.

Description

technical field [0001] The invention relates to a polymerization process of raw rubber, in particular to a production process and equipment of methyl vinyl silicone rubber. Background technique [0002] Methyl vinyl silicone rubber is a functional polymer material. Due to its chemical structure of linear polysiloxane, that is, the chain is composed of Si-O-Si bonds, it has excellent thermo-oxidative stability, weather resistance, high Gas permeability, electrical insulation, non-toxic and harmless, physiological inertness and other properties unmatched by other materials, so it is widely used in aerospace, electrical appliances, electronics, petrochemicals, textiles, automobiles, medicine, food processing and daily products processing Field, known as "industrial monosodium glutamate", plays an increasingly important role in the optimization and upgrading of high technology and industrial structure, and is one of the indispensable new materials for the development of the 21st...
