Abstract

The invention belongs to the technical field of chemical industry production equipment, and particularly relates to a polysulphide silane coupling agent production device. The device comprises a material feeding chamber, a reaction chamber, an exhaust absorption chamber and a waste liquid storage chamber. A vacuum pump makes the reaction chamber stay in a negative pressure state, so that the reaction is conducted in the negative pressure state, less byproduct mercaptopropyltriethoxysilane is generated, and the production quality is improved; due to a secondary spray device of the exhaust absorption chamber, sulphur containing gas can be fully absorbed by alkali liquor, and some unabsorbed sulphur containing gas escapes through a liquid screen in an overflow hole in a liquid sealing plate so as to be fully contacted with the alkali liquor to be absorbed, thereby being prevented from damaging human body and polluting environment.

Description

technical field [0001] The invention belongs to the technical field of chemical production equipment, in particular to a polysulfide silane coupling agent production device. Background technique [0002] Polysulfide silane coupling agent is an important auxiliary agent for the production of green tires. It is widely used in the products of sulfur vulcanized rubber system. It can improve the performance of products by coupling inorganic fillers or fibers with rubber matrix. Used in tires, especially to improve the friction resistance, rolling resistance and wet skid resistance of tires. At present, the polysulfide silane coupling agent products on the domestic market generally have a smell similar to the smell of hydrogen sulfide rotten eggs, which is caused by the smelly sulfur-containing impurities in the product, such as impurities hydrogen sulfide, mercaptosilane, etc. . [0003] In the prior art, the polysulfide silane coupling agent generally adopts normal-pressure pr...
