Problems solved by technology

[0003] The cold-resistant acrylic rubber used in the domestic automobile industry has been occupied by foreign rubber for a long time. The minimum operating temperature of domestic acrylic rubber cannot reach -30°C, or although it can meet the cold-resistant requirements, its comprehensive properties such as strength and oil resistance are not good. Roller sticking is prone to occur during post-processing, resulting in poor post-processing performance

Embodiment 1

[0033] Rubber was prepared according to the formula and process parameters in Table 1.

[0034] preparation steps

[0035] 1) Basic monomer ingredients: mix methyl acrylate, ethyl acrylate, butyl acrylate, ethyl methoxyacrylate, and vulcanization point monomers in a premixing tank in proportion to make a hydrocarbon phase solution for later use;

[0036] 2) Put the emulsifier into the reaction kettle, fully stir for standby;

[0037] 3) Emulsion polymerization: Put the hydrocarbon phase solution prepared in step 1) into the reaction kettle in proportion, stir well, add an initiator in proportion between 5-50°C to initiate the reaction, control its reaction speed and peak value, until the hydrocarbon phase reaction is complete;

[0038] 4) Salt polymerization: Send the fully reacted glue in step 3) to the coagulation pool with compressed air to mix with the coagulant, break the emulsion at a temperature of 20-70°C, and coagulate into a white solid elastomer, which is ready af...

Abstract

The invention discloses a cold-resistant acrylate rubber as well as preparation and application thereof. As the total weight of acrylate monomer and vulcanization point monomer is 100%, the cold-resistant acrylate rubber comprises the following raw materials in percentage by weight: 0-30% of methyl acrylate, 20-50% of ethyl acrylate, 30-60% of butyl acrylate, 8-30% of methoxyl ethyl acrylate, 1-5% of vulcanization point monomer, 0.0001-1% of initiator, 1-10% of emulsifying agent and 2-40% of flocculant. The cold-resistant acrylate rubber is prepared by using an emulsion polymerization method, and can be used for automobiles, motorcycles, transformers, rubber tubes and the like.

Description

technical field [0001] The invention is a synthetic acrylic rubber, in particular to cold-resistant acrylic rubber and its preparation and application. Background technique [0002] Domestic cold-resistant acrylic rubber is an elastomer formed by emulsion polymerization with ethyl acrylate as the main monomer and vinyl monochloroacetate as the vulcanization point monomer. Because its main chain is a saturated structure, it is oil-resistant and resistant. properties such as oxidation. For the cold-resistant type, the minimum operating temperature of domestic acrylic rubber is about -23°C, which cannot meet the requirements of auto parts for acrylic rubber. [0003] The cold-resistant acrylic rubber used in the domestic automobile industry has been occupied by foreign rubber for a long time. The minimum operating temperature of domestic acrylic rubber cannot reach -30°C, or although it can meet the cold-resistant requirements, its comprehensive properties such as strength and...
