Embodiment 1

[0063] Add 37g of calcium hydroxide into a three-necked flask equipped with methanol solvent, put it on an iron stand and stir, then add dropwise the acetylacetone solution containing 100g of acetylacetone dry weight, the reaction temperature is 25°C, and stir for 1 hour to react. Then, 37 g of calcium hydroxide was added to the reaction system, the reaction temperature was maintained at 25° C., and the stirring reaction was continued for 1 hour. The molar ratio of the total amount of calcium hydroxide used to acetylacetone is 1:1.

[0064] After the reaction, filter the reaction product with suction, and use the obtained filtrate for later use. Then weigh the filter cake and dry it in an oven at 105°C. After drying, it is pulverized to obtain the acetylacetone-calcium composition, and then weigh the obtained product to calculate The yield is 94.87%. The characteristic odor of the acetylacetonate-calcium composition obtained in this example is weakened.

[0103] Add 37g of calcium hydroxide into a three-necked flask filled with water, place it on an iron stand and stir, then add dropwise an acetylacetone solution containing 180g of acetylacetone dry weight, the reaction temperature is 20°C, and stir for 0.25 hours. Then, 37 g of calcium hydroxide was added to the reaction system, the reaction temperature was maintained at 20° C., and the stirring reaction was continued for 0.25 hours. The molar ratio of calcium hydroxide and acetylacetone used is 1:1.8.

[0104] After the reaction, filter the reaction product with suction, and use the obtained filtrate for later use. Then weigh the filter cake and dry it in an oven at 105°C. After drying, it is pulverized to obtain the acetylacetone-calcium composition, and then weigh the obtained product to calculate The yield is 96.46%. The characteristic odor of the acetylacetonate-calcium composition obtained in this example is weakened.

Embodiment 3

[0108] Add 37g of calcium hydroxide to a three-necked flask filled with methanol, stir on an iron stand, then dropwise add acetylacetone solution containing 160g dry weight of acetylacetone, the reaction temperature is 30°C, and stir for 0.5 hours. Then, 37 g of calcium hydroxide was added into the reaction system, the reaction temperature was maintained at 30° C., and the stirring reaction was continued for 0.5 hours. The molar ratio of calcium hydroxide and acetylacetone used is 1:1.6.

[0109] After the reaction, filter the reaction product with suction, and use the obtained filtrate for later use. Then weigh the filter cake and dry it in an oven at 105°C. After drying, it is pulverized to obtain the acetylacetone-calcium composition, and then weigh the obtained product to calculate The yield is 96.06%. The characteristic odor of the acetylacetonate-calcium composition obtained in this example is weakened.

Abstract

The invention provides an acetylacetone metal component, a precreation method for the acetylacetone metal component, a plastic and the application of heat stabilizer. The acetylacetone metal component has the following general formula: (OH)x.A<n+>y.Bz, wherein A expresses a metal ion, n expresses the valence of the metal ion, B expresses an acetylacetone anion, and a relationship among n, x, y and z is n*y=x+z. Metal hydroxide or metallic oxide reacts with salt of acetylacetonate to obtain the acetylacetone metal component. By use of the acetylacetone metal component disclosed by the invention, cost is lowered, and characteristic odors are reduced. The acetylacetone metal component is used for the plastic (especially polyvinyl chloride) as the heat stabilizer, and the heat stabilization effect of the acetylacetone metal component is equivalent to the heat stabilization effect of traditional calcium acetylacetonate.

Description

technical field [0001] The invention relates to the field of plastic additives, in particular to a metal acetylacetonate composition and a preparation method thereof. The invention also relates to the application of the acetylacetonate metal composition as a heat stabilizer to plastics, especially polyvinyl chloride. Background technique [0002] Polyvinyl chloride, the English name is polyvinyl chloride, abbreviated as PVC. Polyvinyl chloride is one of the most important thermoplastic resins, and its output has ranked second in the world, second only to polyethylene. The chemical properties of polyvinyl chloride are relatively stable, with properties such as acid and alkali corrosion resistance, high mechanical strength, and flame retardancy. Its products also have many excellent properties such as soft light, high mechanical strength, chemical corrosion resistance, transparency, insulation, and flame retardancy. Excellent performance, widely used in production and life f...
