Problems solved by technology

However, the hydrotalcites used here are described as either natural or synthetic products, but no mention is made of zinc-modified hydrotalcites
In addition, it cannot be seen from the use of the above-mentioned halogen-containing resin composition, but there is no description that it has transparency and exhibits an excellent effect on coloring resistance, especially heat coloring resistance, so it cannot be obtained. opinion

[0118] The formulations listed in the following Table 1 were blended using a Henschel mixer, and kneaded using a roller under the conditions of 170° C.×30 rpm×0.6 mm×3 min to produce a sheet. The surface of the drum after kneading was visually observed, and was performed under the following evaluation conditions. Among them, 0.6mm is the interval between the rollers. The results are shown in Table 1.

[0119] The obtained sheet was placed in a Geer oven at 190° C. and 200° C., and the blackening time (minutes) was measured respectively as . The results are shown in Table 1.

[0120] In addition, the 0.6-mm-thick sheets obtained above were bonded together, and press-processed at 190 degreeC for 5 minutes or 30 minutes, and each 1-mm-thick sheet was produced.

[0121] Using these sheets, a colorability test and a transparency test were performed by the following methods. The results are shown in Table 1.

[0122] In addition, as a comparative example, a composition in whic...

Abstract

Disclosed is a vinyl chloride resin composition for transparent products, which comprises 100 parts by mass of a vinyl chloride resin, and additionally comprises (A) 0.001 to 10 parts by mass of at least one organic acid zinc salt, (B) 0.001 to 10 parts by mass of at least one zinc-modified hydrotalcite compound, and (C) 0.001 to 1.0 part by mass of at least one component selected from the group consisting of mannitol, maltitol and lactitol. Also disclosed is a molded transparent article produced by molding the composition. The molded transparent article is characterized by having long-lasting high transparency and also having excellent heat resistance, discoloration resistance and thermal discoloration resistance.

Description

technical field [0001] The present invention relates to a vinyl chloride resin composition suitable for making transparent products. More specifically, the present invention relates to a transparent product that does not use heavy metal stabilizers, especially tin stabilizers. Vinyl chloride resin composition. Background technique [0002] Vinyl chloride-based resins can be easily adjusted in hardness by adding a plasticizer, so they can be used in various applications. In particular, rigid vinyl chloride-based resin compositions containing no plasticizer at all or semi-rigid vinyl chloride resin compositions containing a small amount of plasticizer are excellent in rigidity, and thus are widely used in building materials and the like. Therefore, in the case of these hard or semi-rigid vinyl chloride resin compositions, needless to say, when processing exposed to high temperature and high pressure, more heat stability and weather resistance are also required when forming mo...
