Abstract

The invention relates to a preparation method of a liquid barium-zinc composite heat stabilizer, belonging to PVC (polyvinyl chloride) assistants in the field of fine chemical engineering. The method comprises the following steps: preparation of barium monomer: reacting mixed organic acid with barium hydroxide monohydrate by using a high-efficiency solvent as a medium under the action of a phosphite chelator to obtain the barium monomer; preparation of zinc monomer: by using the high-efficiency solvent as the medium, reacting mixed organic acid with zinc oxide to obtain the zinc monomer; and barium-zinc compounding: compounding the barium monomer, the zinc monomer, phosphite, an antioxidation combination, a reactive solvent and an antiprecipitant to obtain the environment-friendly liquid barium-zinc composite heat stabilizer product. The stabilizer ensures the transparency of the transparent product, has favorable heat resistance and processibility when being used for producing pure white artificial leather and automobile interior leather from a white filler, avoids the phenomenon of discoloration of the PVC product due to thermal and oxidative aging, enhances the brightness and whiteness of the pure white artificial leather, and has obvious beneficial effects.

Description

technical field [0001] The invention relates to a preparation method of a PVC auxiliary agent, in particular to a preparation method of a liquid barium-zinc composite heat stabilizer, which belongs to the PVC auxiliary agent in the field of fine chemical industry. Background technique [0002] Polyvinyl chloride (PVC) is one of the most widely used synthetic resins in the world. It is widely used in various fields of people's life because of its excellent performance and low price. In the process of processing, it is easy to degrade and color, and in severe cases, blackening occurs, and the processing performance is lost. The heat stabilizer is researched and developed under this background, and has become an indispensable functional aid in the process of PVC processing and manufacturing. agent. Traditional heat stabilizers usually contain heavy metal elements such as lead and chromium, which have certain toxicity and cause serious pollution to the environment. In recent y...
