Problems solved by technology

However, the low-temperature properties of the existing acrylate rubbers are determined by the length of the side group chains. However, longer side chains, such as polymers of butyl acrylate or isooctyl acrylate, seriously impair the oil resistance of acrylate rubbers. Low temperature resistant rubber without compromising oil resistance has become an urgent problem to be solved in the field of acrylic rubber synthesis technology

Abstract

The invention discloses a polyacrylate composition. The polyacrylate composition is prepared from the following components in percent by mass: 10-60% of ethyl acrylate, 10-50% of butyl acrylate, 10-50% of methoxyethyl acrylate and 2-5% of a crosslinking monomer, wherein the ethyl acrylate, the butyl acrylate, the methoxyethyl acrylate and the crosslinking monomer are mixed according to reasonableproportions to prepare acrylate rubber; tests show that the acrylate rubber can withstand low temperatures of -30 DEG C; the methoxyethyl acrylate content is medium; the oil resistance is relatively good and stable.

Description

Technical field [0001] The invention relates to the technical field of rubber synthesis, in particular to a polyacrylate composition. Background technique [0002] Acrylic rubber (abbreviated as ACM) is obtained by polymerizing alkyl acrylate or alkoxyalkyl acrylate. It has the advantages of cold resistance, oil resistance, especially oil resistance at high temperatures, etc. in accordance with the use environment . Therefore, the demand for acrylate rubber as automotive hoses, oil seals, O-rings, equipment / machine built-in conveyor belts, etc. is increasing. However, the low temperature characteristics of the existing acrylic rubber are determined by the chain length of the side groups. However, longer side chains, such as polymers of butyl acrylate or isooctyl acrylate, seriously impair the oil resistance of acrylic rubber. Rubber that is resistant to low temperatures without compromising oil resistance has become an urgent problem in the technical field of acrylic rubber syn...
