CONSTITUTION:A resin composition formed by adding a halogen oxyacid as a stabilizer to a halogenated resin. As the halogen oxyacid used, perchloric acid is particularly desirable. The amount of the oxyacid added is desirably 0.05-5 pts.wt. per 100 pts.wt. halogenated resin. In order to entrance the dispersibility of the oxyacid and to improve the thermal aging resistance of the composition, it is possible to add at least one organometallic salt of Li, Na, K, Ca, Mg, Sr, Ba, Al, Zn, Sn or the like in addition to the oxyacid.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to stabilized halogen-containing resin compositions.

Specifically, the present invention provides a method for adding halogen oxygen e to a halogen-containing resin.
Add IR, and then add lithium and sodium.

Potassium, calcium, magnesium, strontium, barium, aluminum, zinc, tin.

antimony, manganese, sericum, steel, nickel.

It is made by using at least one cobalt organometallic salt compound or polyvinyl alcohol. The present invention relates to a stabilized halogen-containing resin composition characterized by excellent thermal stability in high bulk and long-term low-temperature heat storage, and an effect of preventing discoloration.

[Electrical charging to be solved by conventional technology and invention] Hcl
R-containing resins are inherently thermally unstable resins, and dehydrogenation and dehydrogenation occur mainly within the molecular chain due to heating during molding processing and an increase in the surface temperature of the molded product due to sunlight during use. It is easy to cause decomposition reactions due to this, and as a result, the color tone of the molded product deteriorates and the mechanical properties deteriorate.

Conventionally, in order to eliminate such drawbacks, stabilizers such as various organic acid metal salts, organic tin compounds, epoxy compounds, and organic phosphite esters are used singly or in combination of several kinds to stabilize the heron-containing resin. It is added to improve thermal deterioration during molding and use of molded products.

The halogen-containing resin compositions stabilized by the addition of various conventionally known stabilizers have excellent performance, and by adding plasticizers, etc., molded products can be produced that can fully meet the wide variety of quality requirements in the market. It is an extremely useful material. In recent years, molded products made from such halogen-containing resin compositions have come to be frequently used in interior parts of vehicles such as automobiles, and the range of use has also been expanded for the purpose of reducing the weight of vehicles.

For the purpose of improving the overall feel of molded vehicle interior parts made of such halogen-containing resin compositions, such as rebound resilience, many methods have been adopted in which polyurethane foam is bonded to the back surface or injected inside. ing. In addition, in recent years, the Ouda Slash molding process, in which powder is integrally molded, has become popular, and thermal stability at very high mold temperatures of about 220 to 250°C is required. Molded products for vehicle interior parts are required to withstand severe usage conditions, such as being exposed to heat for long periods of time at relatively low temperatures ranging from 70°C to a maximum of 140°C, depending on the use and purpose. has been done. In response to such thermal history such as low-temperature heat storage over a long period of time, molded parts for vehicle interior parts made of halogen-containing resin compositions are made by adhering to polyurethane foam or injecting polyurethane foam into the interior. This will cause disadvantages to the wearer, such as deterioration of the color and deterioration of the color tone. This decrease in mechanical properties and deterioration of color tone may be caused by the presence of halogen compounds, cyanide compounds, etc. that remain in the polyurethane foam used in combination or that the polyurethane foam decomposes due to heat. It is surmised that this transfers to the molded product layer made of the resin composition, further accelerating heat storage deterioration of the o f -containing resin composition.

The stabilizing effect of the halogen-containing resin composition cannot be said to be sufficient for conventionally known stabilizers used for such purposes, and among organic metal salt compounds, rum salt and lead salt are particularly Its use as a stabilizer is severely limited due to its toxicity.

In recent years, various metal salts of chloric acids, typified by perchloric acid, have been proposed as stabilizers for the herodane-containing resins for this purpose. For example, JP-A-59-18424
No. 0 and JP-A No. 61-34042 disclose the use of a metal salt of heron oxyacid alone or in combination with a zinc salt of an organic acid and an aluminosilicate having a zeolite crystal structure.
JP-A No. 61-78874 proposes the addition of a metal silicate treated with perchlorate, and JP-A No. 62-39652 proposes the combination of a metal perchlorate and a hindered amine compound for soft applications. ing. However, these metal salts of hero-R7 acid complex are subject to thermal deterioration (hereinafter referred to as low-temperature Although it is noteworthy that improvements in aging properties (referred to as aging properties) have been observed, the results are still unsatisfactory and the performance has not yet been achieved, and there is a demand in the market for further improvements in long-term thermal stability and low-temperature aging properties.

[Means for solving Section W11] In view of the current situation, the present inventors have conducted extensive research and have found that thermal stability at high temperatures and heat storage at low temperatures of 70°C to 140°C for a relatively long period of time have been achieved. The present invention has been achieved by discovering a stabilized halogen-containing resin composition that is excellent in preventing deterioration.

That is, the present invention provides a resin composition containing a halogen oxyacid and an organic oxyacid, which is obtained by adding 710rn oxyacid to a resin containing 0.0rn halogen oxyacid, and a resin composition containing a halogen oxyacid and an organic % made by adding one or more metal salt compounds
