Abstract

The invention which relates to a special metal salt monomer for a vegetable oil based liquid heat stabilizer and a preparation method thereof belongs to the technical field of fine synthesis and high-molecular material application. According to the invention, low price fatty acid oleic acid and calcium hydroxide or magnesium hydroxide directly undergo a solid-liquid one-step reaction to prepare avegetable oleic acid calcium or vegetable oleic acid calcium monomer with high metal contents and heat resistance; or vegetable oleic acid, isocaprylic acid, p-tert-butylbenzoic acid and zinc oxide directly undergo a one-step reaction to prepare a mixed acid zinc monomer with high transparency and heat resistance. The preparation method which has a simple technology overcomes pollutions of a large amount of wastewater because of traditional double decomposition methods, the prepared monomer has the advantages of no toxicity, no heavy metals, environmental protection, low price and the like, and the monomer which can be reacted with an auxiliary heat stabilizer phosphite, an oxidant and the like to prepare a two-component or multiple-component composite liquid heat stabilizer is a special environmental-protection high-efficiency metal salt monomer for the high efficiency composite liquid heat stabilizer, so the monomer of the invention has a very good application prospect.
