Abstract

PURPOSE:To provide the subject non-toxic composition containing a hydrotalcite compound, a polyhydric alcohol, a fatty acid zinc salt having specific electrical conductivity and a beta-diketone compound and having excellent electrical insulation, heat-stability and colorability. CONSTITUTION:The objective composition is produced by compounding (A) a vinyl chloride resin with (B) a hydrotalcite compound [preferably an Mg.Zn.Al compound such as mg3.5Zn1.0Al2(OH)13.3.5H2O], (C) a >=3-hydric alcohol (e.g. trimethylolpropane), (D) a fatty acid zinc salt having an electrical conductivity of <=50mul/OMEGAcm and (E) a beta-diketone compound (metal salt) (e.g. dibenzoylmethane). The component D is e.g. zinc stearate. It is preferable to directly react a fatty acid with oxide, hydroxide or carbonate of zinc under melting in order to get the electrical conductivity of <=50mul/OMEGAcm.

BACKGROUND OF THE INVENTION Vinyl chloride resins contain various stabilizers and additives in order to satisfy the thermal stability and processability during molding and the electrical and mechanical properties of products. I need. Among them, vinyl chloride products such as electric wires and insulating tapes require electrical insulation and thermal stability, and therefore lead-based stabilizers such as tribasic lead sulfate and lead stearate are mainly used. However, in recent years, due to problems such as safety for human body and industrial waste, detoxification of plastic additives has been avoided, and non-toxic stabilizers having electric insulation and thermal stability that can replace lead stabilizers. Was desired to be developed. Therefore, the present inventors have found that (1) a hydrotalcite compound, (2) at least one of trivalent or higher polyhydric alcohol compounds, and (3) a conductivity of 50 μ1 / Ω / c.
It was found that such problems can be solved by using a fatty acid zinc of m or less, and a patent application was previously filed. However, in the case of black and gray products, these (1) (2) (3 Although there is no problem with the composition of 1), it has been found that the coloring property is insufficient in the white type and the light type.
