preparation example 1

[0051] Preparation Example 1 (Preparation Example 1 of Inorganic Compound Surface-treated with Organic Modifier)

[0052] Based on 100 parts by weight of the inorganic compound, glycerol monostearate is added in an amount of 10 parts by weight to the 4 al 2 (OH) 12 CO 3 ·3H 2 O or Mg 4 Zn 2 al 2 (OH) 12 CO 3 ·3H 2 O structure and 0.5 μm (micrometer) or 10 μm (micrometer) particle size hydrotalcite, followed by heating at 180° C., thereby preparing an inorganic compound surface-treated with an organic modifier.

preparation example 2

[0053] Preparation Example 2 (Preparation Example 2 of Inorganic Compound Surface-treated with Organic Modifier)

[0054] Except that stearic acid is used in an amount of 1 part by weight based on 100 parts by weight of the inorganic compound instead of glycerol monostearate, the same method as Preparation Example 1 was used to prepare 4 al 2 (OH) 12 CO 3 ·3H 2 O or Mg 4 Zn 2 al 2 (OH) 12 CO 3 ·3H 2 Inorganic compounds with O structure and 0.5 μm (micrometer) or 10 μm (micrometer) particle size surface-treated with organic modifiers.

Embodiment 1

[0055] Example 1 (Inorganic compound 1 undergoing bulk polymerization and surface treatment with organic modifier)

[0056] Except when the polymerization conversion rate is 10% or less than 10%, 0.01 parts by weight of the 0.5 μm (micrometer) particle size and Mg prepared in Preparation Example 1 are added. 4 Al 2 (OH) 12 CO 3 ·3H 2 Except for the hydrotalcite of the O structure surface-treated with an organic modifier, the same method as in Comparative Example 1 was repeated. Optical microscope images of the obtained seeds are shown in figure 1 Optical microscope images of neutralized final particles in c are shown in figure 1 d.

Abstract

The present invention relates to a production method for a vinyl chloride-based resin having outstanding particle uniformity and heat stability, which is advantageous in that, by using an inorganic dispersion that has a specific structure while also being able to eliminate hydrogen chloride in a step in which a vinyl chloride resin is produced, a vinyl chloride resin will be produced that has outstanding particle uniformity and heat stability and also the thermal decomposition temperature of the resin is increased such that it is possible to even improve the product whiteness and physical properties during processing.

Description

technical field [0001] The present invention relates to a method for producing a vinyl chloride-based resin exhibiting excellent particle uniformity and thermal stability. More specifically, the present invention relates to a method for producing a vinyl chloride-based resin exhibiting excellent particle uniformity and thermal stability, wherein, by using a dispersion of an inorganic compound having a specific crystal structure, it is possible to produce a Homogeneity and thermal stability of vinyl chloride resin, hydrogen chloride can be removed from said inorganic compound dispersion during the preparation of the vinyl chloride resin, and the product can be improved during processing by increasing the thermal decomposition temperature of the resin whiteness and physical properties. Background technique [0002] In vinyl chloride resins, particle size and internal structure are important basic factors affecting the handling of the resin, the degree of mixing the resin with...
