Abstract

The invention belongs to the technical field of rubber and plastic products, and provides a DOP-free rubber and plastic product. The DOP-free rubber and plastic product comprises, in parts by mass, 15-20 parts of nitrile rubber, 5-7 parts of polyvinyl chloride resin, 3-5 parts of a ethylene-vinyl acetate copolymer, 20-30 parts of talcum powder, 13-15 parts of chlorinated paraffin oil, 1-2 parts ofepoxidized soybean oil, 2-4 parts of protective wax, 3-5 parts of white carbon black, 0.2-0.3 part of an active agent, 0.1-0.3 part of stearic acid, 10-20 parts of a flame retardant, 0.1-0.3 part ofan anti-aging agent, 1-3 parts of an accelerant, 0.1-0.3 part of a vulcanizing agent, 0.5-1 part of EDDHA-Na, 0.8-1.2 parts of sodium diamyl sulfosuccinate, 1-2 parts of di-n-butylamine and 1-1.5 parts of cyclopentylamine. By means of such a technical scheme, the problem that DOP-free rubber is poor in comprehensive performance in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and relates to a DOP-free rubber and plastic product and a preparation method thereof. Background technique [0002] At present, rubber and plastic products are generally produced with nitrile rubber and polyvinyl chloride resin as the main materials, chlorinated paraffin oil and DOP as plasticizers, and other auxiliary materials are added, and they are prepared by vulcanization and foaming. Dioctyl Phthalate (Dioctyl Phthalate), referred to as Dioctyl Phthalate (DOP), is an organic ester compound and a commonly used plasticizer, which can be widely used in PVC cable materials, leather, synthetic leather, In all products using plasticizers such as transparent materials, soft and hard pipes, edge banding, acrylic boards, rubber, polyurethane, foam sandals, soft boards, paints, glues, adhesives, and decorative materials, DOP is not environmentally friendly. Harmful to the human...
