Abstract

The invention discloses a preparation method of a novel rubber additive. The novel rubber additive is prepared from the following components in parts by weight: 20-30 parts of vinyl resin, 18-25 parts of unsaturated polyester resin, 12-16 parts of unsaturated fatty acid, 1.5-2 parts of zinc oxide and 6-9 parts of trifluoropropyl methyl dichlorosilane. The preparation method comprises the steps of adding unsaturated fatty acid into a container, heating to the temperature of 80-90 DEG C for melting, stirring, then adding zinc oxide, raising the temperature to 120-130 DEG C, and reacting for 2-3 hours to obtain viscous liquid; and adding the viscous liquid obtained in the step S1 into vinyl resin, unsaturated polyester resin and trifluoropropyl methyl dichlorosilane, raising the temperature to 110-115 DEG C, and carrying out melt blending for 3-5 hours to obtain the additive.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a preparation method of a novel rubber additive. Background technique [0002] Processing aid is a kind of compound material. Although it is used in a small amount in rubber compound, it can improve the operation performance of the compound and improve the quality of rubber products. There are many classifications of processing aids, including homogenizers, dispersants, plasticizers, lubricants, peptizers, etc. In terms of improving processing performance, the most basic conditions for processing aids are: compatibility with rubber and its compounding agents; non-polar groups with long chains and easy migration into rubber molecules; polar groups for inorganic compounding agents Has strong affinity; easy to add and has a suitable melting point. However, it is impossible for most processing aids to have all the conditions, and a processing aid cannot have the ...
