硬脂酸
Stearic acid
特性:硬脂酸即十八烷酸,不含不饱和键的脂肪酸,由油脂水解产生。白色或微黄色结晶粉末,融化后成透明状液体。
Physical properties: Stearic acid, also known as octadecanoic acid, a fatty acid without unsaturated bonds, is produced by hydrolysis of oils. White or slightly yellow crystalline powder, it becomes a transparent liquid after melting.
用途:主要用于制造各种硬脂酸盐类、橡胶助剂等。在橡胶的合成和加工过程中起重要作用,是天然胶、合成橡胶和胶乳中广泛应用的硫化活性剂,也可用作增塑剂和软化剂。在生产合成橡胶过程中需加硬脂酸作乳化剂,在制造泡沫橡胶时,硬脂酸可作起泡剂,硬脂酸还可用作橡胶制品的脱模剂。
Uses: Mainly used in the manufacture of a variety of stearic acid salts, rubber auxiliaries, etc.. It plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing active agent in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener. In the production of synthetic rubber, stearic acid is used as emulsifier, in the manufacture of foam rubber, stearic acid can be used as a foaming agent, stearic acid can also be used as a mold release agent for rubber products.
