    摘要： A composition for incorporating in rubber comprises, by weight, 40 to 59% of paraffin wax, 10 to 14% of an oleate of zinc, magnesium, calcium, strontium or barium, 5 to 8% of a potash soap of a C12-C18 saturated fatty acid, 14 to 17% of a C12-C18 saturated fatty acid, 4 to 20% of a polyethyleneglycol alkyl ether, polyethyleneglycol alkylphenol ether, or a polyethylene-glycol (mol. wt. 100-400) monoester of a C13-C21 fatty acid, 5 to 10% of an alkyl glycol having water and oil solubility and from 1 to 4 methyl or methylene groups not directly connected to the hydroxyl groups or polyglycols of the said compounds, and from 3 to 5% of branched or straight chain C4-C18 fatty alcohols.ALSO:A composition for adding to natural and synthetic rubber comprises 10 to 14% of an oleate of zinc, magnesium, calcium, strontium, or barium, from 5 to 8% of a potash soap of a C12-C18 saturated fatty acid, from 14 to 17% of a C12-C18 saturated fatty acid, from 4 to 20% of a polyethyleneglycol alkyl ether, polyethyleneglycol alkylphenol ether, or a polyethyleneglycol (molecular weight 100-400) monoester of a C13-C21 fatty acid, from 5 to 10% of an alkylgycol having water and oil solubility and from 1 to 4 methyl or methylene groups not directly connected to the hydroxyl groups or polyglycols of the said compounds, from 3 to 5% of branched or straight chain C11-C18 fatty alcohols, and from 40 to 59% of one or more of petrolatum, mineral oils or paraffin wax.
