Embodiment 1

[0035] A preparation method of a calcium-zinc stabilizer for shoe materials, comprising the following steps:

[0036] S1. Weigh 1-10 parts of zinc stearate, 10-25 parts of calcium stearate, 0.1-2 parts of zinc acetylacetonate, 0.5-3 parts of calcium acetylacetonate, 20-50 parts of hydrotalcite, epoxy soybean oil 5-15 parts, lubricant 2-16 parts, other metal soaps 5-20 parts, organic auxiliary heat stabilizer 5-25 parts, unsaturated ester 1-10 parts, antioxidant 0.1-2 parts, dispersant 1 ~5 copies;

[0037]S2. Use low-speed mixing equipment to mix the materials. First, mix the various powders evenly, then add the epoxy soybean oil, lubricant, and dispersant of the liquid components, and continue to stir until the materials are in the form of powder or paste with a certain humidity. mixture, namely to obtain the calcium-zinc stabilizer for shoe materials.

[0038] Preferably, the hydrotalcite is layered double metal oxides (Layered Double Hydroxides, LDHs for short), having a ...

Embodiment 2 to 7

[0050] All adopt following a kind of preparation method of shoe material calcium-zinc stabilizer, comprise the following steps:

[0051] S1, weigh each raw material respectively;

[0052] S2. Use low-speed mixing equipment to mix the materials. First mix the various powders evenly, then add liquid components (such as epoxy soybean oil, lubricants, and dispersants), and continue to stir until the materials are powders with a certain humidity or Paste mixture to obtain the calcium-zinc stabilizer for shoe materials.

Abstract

The invention discloses a method for preparing a calcium-zinc stabilizer for shoe materials. The method comprises the following steps: S1. separately weighing 1-10 parts of zinc stearate, 10-25 partsof calcium stearate, 0.1-2 parts of zinc acetylacetone, 0.5-3 parts of calcium acetylacetonate, 20-50 parts of brucite, 5-15 parts of epoxidized soybean oil, 2-16 parts of lubricant, 5-20 parts of other metal soap, 5-25 parts of organic auxiliary heat stabilizer, 1-10 parts of unsaturated acid ester, 0.1-2 parts of antioxidant and 1-5 parts of dispersant; and S2. firstly, uniformly mixing variouspowder materials, then, adding a liquid ingredient, i.e., the epoxidized soybean oil, the lubricant and the dispersant, and continuing to carry out stirring until the material is of a wet powder or paste mixture, thereby obtaining the calcium-zinc stabilizer for the shoe materials. The calcium-zinc stabilizer for the shoe materials, prepared by the method, is free of organic lead salts and the like, thereby being environmentally friendly and safe; flying of dust can be effectively lowered; the whiteness and yellowing resistance of the shoe materials can be better guaranteed; the calcium-zinc stabilizer is difficult to separate out; and the color fastness and the like of the shoe materials can be improved.

Description

technical field [0001] The invention relates to the field of stabilizers, in particular to a preparation method of a calcium-zinc stabilizer for shoe materials. Background technique [0002] At present, most of the thermal stabilizers for PVC (polyvinyl chloride) shoes on the market are mixtures of stearates, lead salts and lubricants. Lead is a heavy metal element that is highly toxic to the human body, and shoe materials that are often in contact with the human body (such as PVC slippers or casual shoes made of PVC soles) have higher environmental protection demands than PVC plates and profiled materials. Therefore, conventional lead-containing stabilizers cannot meet market requirements and gradually withdraw from the market; in addition, calcium-zinc stabilizers, which are substitutes for lead-containing stabilizers, are gradually entering the market, but their raw materials are mostly powder, and the production equipment of related domestic industries is poor. , the wo...
