Problems solved by technology

[0003] At present, there are oily organometallic compounds produced by the reaction of mercapto esters and metal oxides (Zn, Ca) in the market, which are directly used as heat stabilizers or one of the components for PVC processing, although oily organometallic complexes are used in PVC The stabilization effect in processing is good, but its production operation is limited, resulting in low overall efficiency and cost performance

Embodiment 1

[0015] Example 1: Take an equivalent amount of mercaptoethanol and zinc oxide with a pure zinc content greater than 50% and react at 100°C for 120 minutes. When the reactant is colorless and transparent, wash with sorbitol solution with a mass concentration of 5%, and filter to obtain an organic metal Zinc compounds.

Embodiment 2

[0016] Example 2: Take an equivalent amount of mercaptopropanol and zinc oxide with a pure zinc content of not less than 50% and react at 80°C for 120 minutes. When the reactant is colorless and transparent, wash with sorbitol solution with a mass concentration of 5%, and filter to obtain Organometallic zinc compounds.

Abstract

The invention discloses a water soluble organic auxiliary heat stabilizer which is characterized in that a mercapto alcohol and a metal zinc oxide are used for synthesis to generate an organic metal complex as the stabilizer; the specific reaction steps are as follows: taking equivalent mercapto alcohol and zinc oxide into reaction at a temperature ranging from 60 to 120 DEG C for 120 minutes, washing by using a 5wt% sorbitol solution when the reactants are colorless and transparent, and filtering to obtain the organic metal complex as the stabilizer. The organic metal complex provided by the invention can be directly used as a PVC (Poly Vinyl Chloride) processing heat stabilizer, and meanwhile as an auxiliary heat stabilizer to improve the primary stability in the PVC processing course, and therefore, the later-stage operation limitation of the mainstream technology is improved and the production efficiency and use efficiency are greatly improved.

Description

technical field [0001] The invention relates to a stabilizer, in particular to a water-soluble organic auxiliary thermal stabilizer. Background technique [0002] As the second largest synthetic resin in the world, the consumption of polyvinyl chloride (PVC) resin is still growing at a rate of 4% per year in recent years, and the structure of PVC itself determines its thermal degradation and aging characteristics. The processing temperature (180°C) is much higher than its decomposition temperature (120-130°C), which determines that heat stabilizers must be added during the processing and molding of PVC products. The existing stabilizers such as lead and tin are due to their performance The limitations of market and economic effects are becoming more and more obvious. In order to meet the requirements of society, market and economy, the development of stabilizers must be developed in the direction of non-toxicity and high efficiency. [0003] At present, there are oily orga...
