Abstract

The invention relates to a method for preparing environment-friendly calcium-zinc composite stabilizing agent, in particular to a method for preparing the environmental-friendly calcium-zinc composite stabilizing agent by adopting efficient chelating technology. The four ingredients of binary or multivariate saturated acid calcium, binary or multivariate saturated acid zinc, antioxidant and co-stabilizer are mixed in a reaction kettle according to certain mass ratios, the mixture is heated in the reaction kettle, and chelating agent with the mass ratio of 5 to 10 percent is added, when the reaction temperature is controlled to be higher than the melting point of lubricant, about 10 to 20 percent of the lubricant is added to the reaction kettle, the mixture is fully mixed, and then the mixture is cooled to a normal-temperature state and stirred at a low speed, thus obtaining the product. The method has the advantages that the coating of the calcium-zinc composite stabilizing agent is modified at a temperature higher than the melting point of the lubricant, thus greatly reducing the hydroscopic property and further increasing the electric resistivity of PVC products. Simultaneously, the stabilizer of static coating modification is more beneficial to PVC dispersion, thus improving the stabilizing effect.

Example Embodiment

[0043] Example 1

[0044] Configure environmentally friendly calcium and zinc stabilizers according to the following formula (by weight):

[0045] 25 parts of calcium zinc metal soap

[0046] Epoxidized soybean oil 20 parts

[0047] Antioxidant 2,6-tertiary butyl-4-methylphenol and bis(3,5-tertiarybutyl-4-hydroxyphenyl) sulfide mixture. 2 servings

[0048] Lubricant mixture of butyl stearate and glyceryl monostearate: 2 parts

[0049] Phosphite 40 parts

[0050] Accelerator β-diketone compound 2 parts

[0051] The dynamic thermal stability experiment was carried out on the double-roller mill at a temperature of 175-180℃, and samples were taken every 5 minutes. The formula is as follows:

[0052] PVC(SG-5) 100

[0053] Calcium zinc stabilizer 3

[0054] ESO 3

[0055] The results showed that adding the self-made liquid calcium-zinc heat stabilizer, the PVC sheet began to change color after 22 minutes.

Example Embodiment

[0056] Example 2

[0057] 30 parts calcium zinc metal soap

[0058] 18 parts of solvent oil, epoxy fatty acid methyl ester mixture

[0059] Antioxidant 4 parts

[0060] Lubricant mixture of glyceryl monostearate and ester wax 1.5 parts

[0061] Co-stabilizer bisulphite 45 parts

[0062]Accelerator β-diketone compound 1.5 parts

[0063] The dynamic thermal stability experiment was carried out on the double-roller mill at a temperature of 175-180℃, and samples were taken every 5 minutes. The formula is as follows:

[0064] PVC(SG-5) 100

[0065] Calcium zinc stabilizer 3

[0066] ESO 3

[0067] The results showed that adding the self-made liquid calcium-zinc heat stabilizer, the PVC sheet began to change color after 30 minutes.

Example Embodiment

[0068] Example 3

[0069] 35 parts of calcium zinc metal soap

[0070] 15 parts of solvent mineral oil, epoxy soybean oil mixture

[0071] Antioxidant 3 parts

[0072] Lubricant 1 part of glyceryl stearate

[0073] Co-stabilizer dibenzoylmethane, phosphite compound 45 parts

[0074] Accelerator β-diketone compound 1 part

[0075] The dynamic thermal stability experiment was carried out on the double-roller mill at a temperature of 175-180℃, and samples were taken every 5 minutes. The formula is as follows:

[0076] PVC (SG-5) 100 copies

[0077] 40 parts of dioctyl phthalate (DOP)

[0078] Calcium zinc stabilizer 3 parts

[0079] ESO 3 copies

[0080] The results showed that adding the self-made liquid calcium-zinc heat stabilizer, the PVC sheet began to change color after 25 minutes.

[0081] At the same time, according to the same formula, the commercially available liquid calcium-zinc heat stabilizer was compared on the double-cylinder mill. As a result, the PVC sheet began to change color after 12 minutes. This shows that the homemade liquid calcium-zinc heat stabilizer has good stability.
