Problems solved by technology

[0003] The existing stabilizer preparation process lacks raw material protection measures, which leads to coking in the process of heating and heating, and in the process of dissolving raw materials, most of them use non-returnable acids, resulting in a large amount of acid in the stabilizer. The impurities seriously affect the stability of the stabilizer, and most of the existing stabilizer solutions are added with a large amount of plasticizers and antioxidants, which are easily affected by water vapor in the environment during storage, thereby affecting the concentration of the stabilizer

Abstract

The invention relates to the technical field of stabilizer preparation, in particular to a a formula and a production process of a high-stability liquid calcium-zinc stabilizer. The formula of the stabilizer comprises zinc oxide, calcium oxide, a plasticizer, an antioxidant, silicon dioxide, a beta-diketone mixture, oxidized vegetable oil and diluted hydrochloric acid. The stabilizer disclosed by the invention has the beneficial effects that raw materials are dissolved by adopting diluted hydrochloric acid capable of returning, a titration dissolution mode is adopted, and excessive hydrochloric acid is returned by heating, so that the content of impurities is greatly reduced, a raw material solution is purified, and meanwhile, an additive and a conditioning agent are fully dissolved by raising the temperature to a boiling state; the stabilizer prepared after mixing is stored in a solid state by heating and evaporating to dryness; and by controlling the heating temperature and the heating rate, the high-purity and high-stability stabilizer meeting the quality requirement is prepared, and meanwhile, the stabilizer is convenient to store.

Description

technical field [0001] The invention relates to the technical field of stabilizer preparation, in particular to a formulation of a high-stability liquid calcium-zinc stabilizer and a production process thereof. Background technique [0002] Calcium-zinc stabilizers are usually divided into: solid calcium-zinc stabilizers and liquid calcium-zinc stabilizers. Calcium-zinc stabilizers are composed of calcium salts, zinc salts, lubricants, antioxidants, etc. as the main components and synthesized by a special composite process. It can not only replace toxic stabilizers such as lead cadmium salts and organotin, but also has very good thermal stability, light stability, transparency and tinting strength. Practice has proved that in PVC resin products, the processing performance is good, and the thermal stability is equivalent to that of lead salt stabilizers. It is a good non-toxic stabilizer. [0003] The existing stabilizer preparation process lacks raw material protection meas...
