Embodiment 1-11

[0017] Calcium glycerol, zinc glycerol and auxiliary heat stabilizer were uniformly mixed in a high-speed mixer according to the ratio in Table 1 to prepare calcium glycerol / zinc composite heat stabilizer.

[0018] Mix the prepared composite heat stabilizer, dioctyl phthalate (DOP) (50 parts), and polyvinyl chloride (PVC) resin (100 parts) evenly, and roll on a double-roll machine with a roll temperature of 150 ° C and a roll distance of 1 mm Molded into flakes, then cut into pellets and put into a test tube. In an oil bath at 180°C, the static thermal stability of the compound was measured according to the national standard GB / T2917.1-2002 Congo Red method. The results are shown in Table 2.

Abstract

The invention provides a glyceryl calcium / zinc composite heat stabilizer for polyvinyl chloride, and belongs to the technical field of polymer material application. The composite heat stabilizer is prepared by uniformly mixing glyceryl calcium, glyceryl zinc and an auxiliary heat stabilizer according to a certain ratio at normal temperature and normal pressure. The composite heat stabilizer can improve the heat stability and colorability resistance of polyvinyl chloride resin; static heat stability test results show that the composite heat stabilizer has long heat stabilizing time more than 110 minutes after complexing; the glyceryl calcium / zinc composite heat stabilizer overcomes the defects of toxicity, heavy metal pollution, poor heat stability and the like of traditional heat stabilizer; the composite stabilizer has the advantages of no toxicity, environmental friendliness, no heavy metal, low price and the like; and the glyceryl calcium / zinc composite stabilizer is an efficient composite stabilizer and has good application prospects.

Description

technical field [0001] The present invention is a glyceryl calcium / zinc composite heat stabilizer for polyvinyl chloride, in particular to the compounding and application of a glyceryl calcium / zinc composite heat stabilizer with excellent performance and non-toxicity for polyvinyl chloride, which belongs to macromolecule Material application technology field. Background technique [0002] Polyvinyl chloride (PVC) plastic is one of the five general-purpose plastics. PVC is the first synthetic resin in my country and the second largest in the world. It has the advantages of low price, flame retardant, corrosion resistance, good transparency, and good electrical insulation. However, PVC The biggest disadvantage is poor thermal stability. At present, the industrial heat stabilizers used in PVC in the world mainly include lead salts, mixed metal salts, organic tin, organic antimony, organic auxiliary heat stabilizers, and rare earths. The world's largest output is still the trad...
