Embodiment 1～4 and comparative example 1 and 2

[0100] After mixing the compounds in Table 1 below using a rock mixer, roll kneading was carried out under the conditions of 190°C x 30 rpm x 0.6 mm x 3 minutes to produce a sheet. The following evaluations were performed on these sheets. The results are shown in Table 1.

[0101] Evaluation of precipitated scaling:

[0102] The evaluation of the deposited scale was performed by visually observing the surface of the roll after roll kneading according to the following .

[0103]

[0104] ○: No attachment

[0105] △: There is a little attachment

[0106] ×: Large attachment

[0107] Evaluation of Thermal Stability:

[0108] The obtained sheet was placed in a 190° C. gear oven, and the thermal stability was evaluated by measuring the blackening time (minutes).

[0109] Evaluation of coloring resistance:

[0110] The obtained 0.6 mm-thick sheets were bonded together and subjected to press working at 190° C. for 5 minutes to obtain 1 mm-thick sheets. The coloring resistan...

Abstract

The present invention provides a vinyl chloride resin composition which has excellent thermal stability, coloring resistance and processability, while containing no stabilizer that contains a heavy metal such as lead, tin or barium. The vinyl chloride resin composition is suitable for use in building materials. The present invention specifically provides a vinyl chloride resin composition which contains (a) an organic acid calcium salt and / or an organic acid zinc salt, (b) calcium acetylacetonate and / or zinc acetylacetonate, (c) a hydrotalcite compound and (d) a polyol mixture respectively in specific amounts relative to a vinyl chloride resin. A polyol mixture having a specific composition is used as the polyol mixture of the component (d).

Description

technical field [0001] The present invention relates to a vinyl chloride-based resin composition. Specifically, it relates to a thermal stability and coloring resistance without using heavy metal-based stabilizers such as lead and tin, which are problematic from the viewpoint of safety and environmental protection. It is a vinyl chloride-based resin composition that is also excellent in properties and processability, and is suitable for building materials. Background technique [0002] Vinyl chloride-based resins can be used in various applications because the hardness can be easily adjusted by adding a plasticizer. Especially rigid (0 to 10 parts by mass relative to 100 parts by mass of vinyl chloride resin) that contains no plasticizer or hardly any plasticizer, or semi-rigid that contains a small amount of plasticizer (relative to 100 parts by mass of vinyl chloride resin) Vinyl chloride-based resin compositions (100 to 50 parts by mass per 100 parts by mass of vinyl chl...
