Abstract

The invention discloses a paraffin-based rubber softening oil and a preparation method thereof. The paraffin-based rubber softening oil comprises: 65-72 wt% of refined paraffin-based base oil, 27-33 wt% of liquid paraffin, and 1-5 wt% of an anti-aging composite agent. The preparation method comprises the following steps: (1) adding the refined paraffin-based base oil to a reaction kettle, heating to a temperature of 60-70 DEG C, and stirring; (2) sequentially adding the liquid paraffin and the anti-aging composite agent; and (3) respectively stirring for 25-35 minutes to obtain the paraffin-based rubber softening oil of the present invention. The paraffin-based rubber softening oil of the present invention has advantages of excellent compatibility, good antioxidation and low volatility, and further has the advantages of simple production process, no toxicity and no harm.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and specifically relates to a paraffin-based rubber softening oil and a preparation method thereof. Background technique [0002] Butyl rubber is a kind of synthetic rubber, a copolymer synthesized from isobutylene and a small amount of isoprene. It went into industrial production in 1943. Butyl rubber products are not easy to leak, and are widely used in industry and civil use. It is generally used to make inner tubes for automobiles and aircraft wheels. [0003] As the plasticizing system of rubber track, rubber oil is the third largest material in the rubber industry after raw rubber and carbon black. It is mainly supplied to rubber product factories to prepare oil used in rubber when producing rubber products. It is mainly used to make self-adhesive waterproof membranes, as softeners, fillers, plasticizers, etc. [0004] First, the classification of rubber oil: [0005] 1 Acco...
