AI Technical Summary

Problems solved by technology

[0003] At present, the main processes for preparing acrylate rubber are premixing, polymerization, demulsification, washing, and drying. There are many steps in the process, and the water consumption is large, which is about 30 tons of water for 1 ton of acrylate rubber. Moreover, the obtained acrylate rubber has a strong odor and poor processing performance. Difference

[0023] The preparation method of the described acrylate rubber that can be directly vulcanized without washing may further comprise the steps:

[0024] (1) Take deionized water, adjust pH ≥ 8 with ammonia water, add fatty acid salt, heat and stir until it is completely dissolved, then add acrylate monomer, vulcanization point monomer, other functional monomers and initiator in sequence Carry out a polymerization reaction, react at 50-80°C for 30 minutes, and then heat-preserve and age at 50-80°C for 4 hours to obtain an acrylate emulsion;

[0025] (2) Heat and concentrate the acrylate emulsion to 35% of the mass of the original emulsion, then cool it down, then freeze-dry it after cooling to room temperature (freeze at -15°C first, freeze-dry at -5°C, 20-50kPa after freezing ), the solid ACM rubber can be obtained.

Abstract

The invention relates to acrylate rubber capable of being directly vulcanized without washing and a preparation method thereof, and belongs to the technical field of acrylate rubber. The disclosed acrylate rubber comprises the following raw materials in percentage by mass: 80-89% of an acrylate monomer, 2-10% of a vulcanization site monomer, 3-5% of fatty acid salt, 5-10% of other functional monomers, and 0.005-0.01% of an initiator, and deionized water is added and the mass of the added deionized water accounts for 200-300% of the total mass of the raw materials. According to the acrylate rubber capable of being directly vulcanized without washing, the acrylate rubber can be directly vulcanized with sulfur, and the vulcanized rubber is excellent in performance; the invention further provides the preparation method which is simple in process and low in water consumption.

Description

technical field [0001] The invention relates to an acrylic rubber that can be directly vulcanized without washing and a preparation method thereof, belonging to the technical field of acrylic rubber. Background technique [0002] Acrylate rubber (polyacrylate rubber, ACM) refers to a copolymer composed of alkyl acrylate monomers and a small amount of monomers with crosslinking active groups. The polymer main chain is saturated and contains polar ester groups, which endows acrylate rubber with oxidation resistance and ozone resistance, and has outstanding hydrocarbon oil swelling resistance, so ACM is suitable for heat-resistant and oil-resistant rubber parts, Pipelines, container linings and cables that have been in contact with oil for a long time, and rubber parts exposed to ozone and weather conditions, such as oil seals, gaskets, transmission parts and bearing seals for automotive hydraulic lubricating oil systems, hydraulic oil transmission hoses, and cable sheaths , o...
