PURPOSE: To obtain abrasion resisting rubber screen from diene rubber, α,β-ethylene unsaturated carboxylic acid, bivalent metallic compound, organic peroxide and aromatic second class amine compound. n CONSTITUTION: (a) Diene rubber, conjugate diene homopolymer of natural rubber, and 1, 3-butadiene, isopreme, chloroprene. (b) α,β-ethylene unsaturated carboxylic acid of methacrylic acid, acrylic acid. The ratio of (a) to (b) in weight is set at 87/13 to 55/45. (c) Bivalent metallic compound, oxide of zinc, magnesium. For 100 parts in weight of (b), (c) is set at 50 to 150 parts in weight. (d) For (a)+(b)=100 parts in weight, organic peroxide of DCP is set at 0.3 to 10 parts in weight. (e) For (a)+(b)=100 parts in weight, aromatic second class amine compound is set at 0.1 part in wight. By heating and solidifying a mixture of these substances, rubber screen is obtained. n COPYRIGHT: (C)1979,JPO&Japio |
