日本专利报导,由生石灰、金属皂、硬脂酸铝、水组成的石灰皂液或由硼砂水组成的硼砂液,并添加共聚物。共聚物成份是乙烯、醋酸乙烯和乙烯的共聚物,重量比是83:17的醋酸乙聚合物乳状液,占总重量的2～5％而组成粘着性好的冷拉用润滑剂。金属冷拉,特别是作为捧钢、钢丝冷拉用润滑剂,以前是用石灰皂润滑保护膜或硼砂润滑保护膜,这种润滑剂为粉末状,将其溶解在适量的水中来使用。但这种润滑剂涂层后,由于振动及线材之间的接触而剥落,明
Japanese patent reports, lime soap consisting of quicklime, metallic soap, aluminum stearate, water or borax liquid consisting of borax water, and adding a copolymer. The copolymer component is a copolymer of ethylene, vinyl acetate and ethylene, the weight ratio is 83:17 acetate polymer emulsion, accounts for 2 ~ 5% of the total weight to form good adhesion of the cold drawing lubricant. Cold-drawn metal, especially as a steel, steel wire cold-drawn lubricant, was previously lubricated with lime soap protective film or borax lubricating protective film, this lubricant is a powder, dissolved in an appropriate amount of water to use. However, after the lubricant is coated, it peels off due to vibration and contact between the wires
