Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl chloride foamable resin composition suitable for high filler compounding and high foaming, and more particularly to a vinyl chloride resin having a filler, a plasticizer, and an overbased alkaline earth metal. Carboxylate phenolate complex,
Good workability by blending overbased zinc organic carboxylate and thermal decomposition type organic foaming agent, good foaming cell and excellent surface condition, high filling compound and high foaming with improved plate-out property It relates to a suitable vinyl chloride foamable resin composition.

[0002]

2. Description of the Related Art In general, vinyl chloride resins are relatively inexpensive and have excellent physical and chemical properties. Therefore, they are used as foam molded articles in furniture products such as lasers, wallpapers, cushioning materials, and automobile articles. It is a suitable material for application.

[0003] Such a foamed molded product is generally prepared by calendering, extruding, or injection molding a composition obtained by adding a plasticizer, a foaming agent, a stabilizer, a filler, a colorant, and the like to a vinyl chloride resin and mixing them. Molding or applying a vinyl chloride sol compound obtained by adding a plasticizer, a foaming agent, a stabilizer, a filler, a colorant, etc. to a paste resin, and applying the mixture to paper or cloth, gelling by applying heat, and molding. Manufactured by

[0004] However, when a foamed molded article is produced by blending a large amount of a filler with a vinyl chloride resin, the viscosity of the PVC sol compound becomes high and the workability is significantly reduced.
Also, when a high foaming molded article is produced by blending a large amount of a foaming agent with a vinyl chloride resin, foam cells are roughened and plate-out often occurs. For example, a method of blending a large amount of a plasticizer to reduce the viscosity of the PVC sol compound and a method of blending a viscosity reducing agent such as petroleum hydrocarbon have been proposed. In some cases, the strength of the foamed cells may be reduced, or the strength may be reduced.

Further, these methods cannot improve the plate-out property. A method of adding a cell conditioner such as an acrylate resin or a methacrylate resin in order to prevent foam cell roughness has been proposed. A satisfactory molded product cannot be obtained. The cell conditioner has neither the effect of lowering the viscosity of the PVC compound nor the effect of preventing plate-out.

Japanese Patent No. 2552334 proposes a method of adding an overbased organic phenolate or carboxylate complex of barium, but this method does not sufficiently improve the plate-out. In addition, the surface condition is poor, and a highly foamed molded article having an excellent degree cannot be obtained.

Further, Japanese Patent Application Laid-Open No. 54-129057 proposes a method of adding a zinc salt of an overbased organic carboxylic acid. In this method, the plate-out is improved, but the cell is roughened. And a highly foamed molded article having a highly excellent surface cannot be obtained.

[0008]

It is an object of the present invention to provide a vinyl chloride foamable resin composition suitable for high filling compounding and high foaming, and a molded product thereof.
