Broadly speaking, chemicals that increase the stability of solutions, colloids, solids, and mixtures are called stabilizers, which slow down the reaction, maintain chemical equilibrium, reduce surface tension, and prevent photo, thermal, or oxidative decomposition. The broad chemical stabilizer has a wide source, and can flexibly use any chemical substance to achieve the purpose of stabilizing the product quality mainly according to the design purpose of a formula designer, in a narrow sense, the broad chemical stabilizer mainly refers to a reagent for keeping high polymer plastics, rubber, synthetic fibers and the like stable and preventing decomposition and aging of the high polymer plastics, rubber, synthetic fibers and the like, and the industrial common heat stabilizer mainly comprises lead salt, metal soap, organic tin, organic antimony, organic rare earth, pure organic compounds and the like. According to the estimation, the heat stabilizer production capacity is 7 kiloton/a at present in China, and the consumption in 2000 is about 8 kiloton/a. The development of lead salt in China focuses on eliminating dust pollution, and related measures are taken at present; the consumption proportion of organic tin in the market of China is low; because the high-performance auxiliary stabilizer cannot be popularized, a composite metal soap system with relatively high cost performance is lacked in the market; the rare earth stabilizer is a living force in the development of the heat stabilizer in China. The consumption of global heat stabilizers has exceeded 30 million t/a, and the united states represents the latest level of development of world heat stabilizers, leading the world in terms of lead-free formation; the yield of the heat stabilizer in Japan is about 6, and lead salts are still the main in case of 7 ten thousand t/a; the consumption of the Western Europe thermal stabilizer is about 11 million t/a, most of the environment-friendly stabilizers in the current market have a part of transparent stabilizer high-zinc-content systems, are good in transparency but insufficient in stability and easy to be subjected to zinc burning, and the other part of transparent stabilizer low-zinc-content systems are poor in transparency and sufficient in stability and difficult to be subjected to zinc burning, so that under the long-term research of a company, a transparent soft PVC environment-friendly stabilizer with a medium zinc content, which is good in transparent effect, strong in stability and free of zinc burning, is finally developed.
