Abstract

The invention discloses chlorinated rubber with the synergistic improvement of the nano additive and polyoxyethylene sodium sulfonate and a preparation method thereof. According to the chlorinated rubber and the preparation method thereof, the nanometer additive preferably selects nano tungsten disulfide. The chlorinated rubber prepared through the preparation method has the advantages of being better in chlorination uniformity, uniform in powder particles, capable of being fully dissolved in organic solvents such as toluene and xylene and good in dissolution transparency. The preparation method has the advantages that the whole reaction process is completed in a water-phase suspension state in a reaction kettle, no pollution is caused to the surrounding environment, the reaction time is short, the operation is simple, the conversion into scale production is easy, and the economic benefit is considerable.

Description

technical field [0001] The invention relates to the field of polymer chemical industry, in particular to a chlorinated rubber synergistically modified by nano-additives and sodium polyoxyethylene sulfonate, its preparation method and application. Background technique [0002] Chlorinated rubber is a rubber derivative product obtained from natural latex or natural rubber or synthetic rubber after chlorination modification, and is widely used in inks, coatings, adhesives and other fields. Before, chlorinated rubber was chlorinated and produced by the solvent method. Due to the high cost of the solvent method, and some solvents such as carbon tetrachloride are harmful to the human body, volatiles pollute the environment and residual solvents in the product are used. There are defects such as limitations. At present, the research of preparing chlorinated rubber by aqueous phase method has obtained certain progress, such as patent documents CN1667000A, CN101260168A and CN1014814...
