Abstract

Chloroprene rubber mixed compound nonstick to rolls is made of, by weight, 60-90 parts of raw chloroprene rubber, 10-40 parts of raw butyronitrile rubber, 2-4 parts of stearic acid, 1-3 parts of accelerant, 1.5-5 parts of anti-aging agent, 40-60 parts of carbon black, 10-30 parts of calcium carbonate, 0.4-2.0 parts of paraffin, 5-10 parts of zinc oxide and 15-30 parts of DOP (dioctyl phthalate). The chloroprene rubber mixed compound is low in material cost, simple, convenient and stable in process and nonstick to rolls, and product performance requirements can be met while production process requirements on low cost and non-stickiness to rolls are met.

Description

technical field [0001] The invention relates to a neoprene rubber compound and a preparation method thereof, in particular to a non-stick roller neoprene rubber compound and a preparation method thereof. Background technique [0002] Chloroprene (CR) is milky white, beige or light brown flakes or lumps, with a density of 1.23-1.25g / cm3, a glass transition temperature of -40-50°C, a fragmentation point of -35°C, and a softening point of about 80℃, decompose at 230~260℃. The solubility parameter of neoprene is δ=9.2~9.41. Soluble in toluene, xylene, dichloroethane, trivanadium ethylene, slightly soluble in acetone, methyl ethyl ketone, ethyl acetate, cyclohexane, insoluble in n-hexane, solvent gasoline, but soluble in a good solvent with an appropriate proportion A mixed solvent composed of a poor solvent and a non-solvent or a poor solvent and a non-solvent can swell in vegetable oil and mineral oil without dissolving. Neoprene has good physical and mechanical properties, ...
