Abstract

The invention discloses a synthetic method of a special environment-friendly zinc-based SY-310 stabilizer for a PVC calendered sheet. The special environment-friendly zinc-based SY-310 stabilizer is prepared from the following components: 1.3-dimethyl-6amino-uracil compound, cyanuric acid, isocaprylic acid, oleic acid, benzoic acid, lauric acid, zinc oxide, calcium oxide, DBM oxide, an SBM antioxidant, an antioxidant 1010, solvent oil, epoxy soybean oil, phosphite ester antioxidants, DBM oxide, SBM oxide, and a catalyst. The synthetic method comprises the following steps: measuring all components: the 1.3-dimethyl-6amino-uracil compound, cyanuric acid, isocaprylic acid, oleic acid, benzoic acid, lauric acid, zinc oxide, calcium oxide, DBM oxide, SBM antioxidant, antioxidant 1010, solvent oil, epoxy soybean oil, phosphite ester antioxidant, DBM oxide, SBM oxide, and a catalyst, and placing the components in to an enamel reaction kettle to react. The synthetic method is excellent in stable effect, simple in processing formula and technology, bright in sheet color, capable of meeting various requirements of the national standard for the mechanical performance, and higher in environmental protection performance compared with the existing stabilizer.

Description

technical field [0001] The invention relates to a stabilizer for PVC processing, in particular to a special environment-friendly zinc-based stabilizer SY-310 stabilizer for producing PVC hard sheets by a calendering process. Background technique [0002] PVC, scientific name polyvinyl chloride, is currently the most widely used plastic in the field of plastic processing, especially in the packaging industry, it is cheap and good, and easy to shape. This industry mainly uses PVC sheets, and in the sheet industry Among them, PVC materials have low manufacturing cost, excellent mechanical properties, good processing performance, corrosion resistance, insulation and other good characteristics, so PVC sheets have been widely used in the construction and decoration industry, pharmaceutical packaging, and food packaging industries. [0003] The stability of PVC material directly affects the quality of PVC products. Therefore, during the processing and preparation of PVC sheets, it ...
