がある。(Prior art) Soft vinyl chloride resin plasticized with a plasticizer has a high degree of flexibility in its hardness and is easy to work with, so it is widely used as interior materials for automobiles, gaskets, industrial parts, etc. This material softens in places exposed to heat and becomes unable to withstand its own weight, making it difficult to maintain its shape, so it cannot be used around car engines or as hoses for flowing high-temperature fluids. There is a drawback.

う欠点がある。Therefore, EPD is used in areas that require such high temperatures.
Thermosetting rubbers such as M are used to increase strength by vulcanizing them during molding, but this increases the vulcanization process and causes variations in quality during vulcanization, so thermoplastic polyester elastomer However, it has been proposed to use soft vinyl chloride resin blended with nitrile rubber for this type of application. However, although this material has good shape retention, it has the drawbacks of poor thermal stability, poor long-term heat aging resistance, and poor light deterioration resistance because it contains a butadiene component.

ての研究を進めて本発明を完成させた。In other words, as a result of various studies aimed at developing a vinyl chloride-based resin composition that provides a vinyl chloride-based resin molded product that has good processability and excellent shape retention even at high temperatures, the inventors found that chloride When acrylic rubber containing 20 to 95% of acrylic content insoluble in methyl ethyl ketone is added to vinyl resin, this product has good processability, and molded products made from this composition have long-term heat aging resistance, light resistance, We discovered that oil resistance was improved and shape retention at high temperatures was also excellent, and we conducted research on the type and amount of acrylic rubber added to the saw, as well as the type and amount of plasticizer added. The present invention has been completed.
以下にこれをさらに詳細に説明する。This will be explained in more detail below.

い。The vinyl chloride resin as the main component constituting the composition of the present invention may be any known one. However, if the average degree of polymerization of this vinyl chloride resin is less than 600, the tensile strength will be weak, and if it is greater than s, o o o, it will be difficult to process, so it should be in the range of 600 to 8,000. However, it may be a vinyl chloride homopolymer, a copolymer, or a partially crosslinked one.

In addition, as long as vinyl chloride resin is the main component, it may be a blend with other polymers, and the blended resins include ethylene-vinyl acetate copolymer, chlorinated polyethylene, ABS resin, AS resin,
Examples include polyurethane and acrylic resin.

がある。Next, the acrylic rubber added to the vinyl chloride resin is an acrylate rubber derived from an alkyl acrylate, an alkoxyalkyl acrylate, or an ethylene-based rubber that is a combination of ethylene and an alkyl acrylate.
It is said to be an acrylate type product, but this is made by adding acrylic rubber Log
When soaked and stirred for 30 minutes, the insoluble content is 20% by weight.
If the amount is less, the shrinkage of the acrylic rubber will be large, resulting in molded products made from this composition having a poor appearance.
If the amount exceeds 100% by weight, the compatibility with the vinyl chloride resin deteriorates, so it needs to be 20 to 95% by weight, preferably 30 to 90% by weight. If the amount is less than 15 parts by weight, the effect of adding this acrylic rubber will be insufficient, and the shape retention effect of the molded product at high temperatures will not be improved.
If it exceeds 15 parts by weight, the appearance of the molded product will deteriorate due to shrinkage of the acrylic rubber, and the cost will increase, so the amount should be in the range of 15 to 150 parts by weight, preferably 30 to 130 parts by weight.

In order to adjust the hardness of a molded article made from a product, it is convenient to add a known plasticizer to the molded article because it does not cause stickiness. Examples of this plasticizer include phthalic acid-based plasticizers such as diisooctyl phthalate and diisononyl phthalate, and trimellitic acid-based plasticizers.

If the amount exceeds 300 parts by weight per 100 parts by weight of resin, the molded product will become sticky and the commercial value will be lost.
The range is 300 parts by weight, preferably 0 to 200 parts by weight.
