た。2. Description of the Related Art A molded article of a chlorinated vinyl chloride resin has a feature of high heat resistance, and is used at a relatively high temperature at which a conventional molded article of a vinyl chloride resin cannot be used due to heat deformation. Used for applications. For example, a chlorinated vinyl chloride resin molded article is used as a pipe for hot water, utilizing the fact that the heat distortion temperature is higher by 20 to 40 ° C. than that of a vinyl chloride resin molded article. Alternatively, a chlorinated vinyl chloride-based resin molded product is used as a sheet for household appliances to which heat is applied, utilizing the fact that the heat deformation temperature is higher than that of the vinyl chloride-based resin molded product. On the other hand, it is known that a molded article of a chlorinated vinyl chloride resin has a high tensile strength at a high temperature, but has a low impact resistance at a low temperature. In order to overcome the low impact resistance at low temperatures, it is known to incorporate an impact modifier such as ABS or MBS into a chlorinated vinyl chloride resin composition. Although these impact modifiers improved the impact resistance at low temperatures, they were not satisfactory. In order to solve this problem, Japanese Patent Publication No.
In the chlorinated vinyl chloride resin composition, ABS and / or
Alternatively, it has been proposed to mix MBS and chlorinated polyethylene. However, although the impact resistance is improved and improved by blending chlorinated polyethylene with the chlorinated vinyl chloride resin composition, the softening temperature of the chlorinated vinyl chloride resin molded product decreases, and the tensile strength at high temperatures decreases. Therefore, the chlorinated vinyl chloride resin composition was insufficient.

~ 1300, more preferably from 600 to 1200,
The chlorination degree of the chlorinated vinyl chloride resin is 62 to 70% by weight, preferably 63 to 70% by weight, more preferably 64 to 70% by weight.
７０70% by weight. If the average degree of polymerization of the vinyl chloride resin as a raw material of the chlorinated vinyl chloride resin is less than 600, sufficient mechanical strength cannot be obtained, while if the degree of polymerization exceeds 1500, It is not preferable because processing is not easy. When the chlorination degree of the chlorinated vinyl chloride resin is less than 62% by weight, a composition having sufficient heat resistance cannot be obtained. On the other hand, when the chlorination degree exceeds 70% by weight,
It is not preferable because the melt viscosity becomes high and processing of the resin composition involves technical difficulties. In the present invention, "vinyl chloride resin" is a homopolymer of vinyl chloride, and other copolymerizable monomers with vinyl chloride, for example, ethylene, propylene, vinyl acetate, allyl chloride, allyl glycidyl ether, acrylic acid Includes copolymers with esters, vinyl ethers and the like.

On the other hand, when only MBS having a butadiene content of more than 30% by weight and 60% by weight or less is used, the impact strength is greatly reduced. The amount of two types of MBS to be blended is
1 for 100 parts by weight of chlorinated vinyl chloride resin
６6 parts by weight. If the amount of MBS to be blended is less than 1 part by weight, the impact resistance of the pipe will be reduced,
Exceeding the weight parts lowers the heat resistance, which is a characteristic of the chlorinated vinyl chloride resin. More preferably, the amount of each of the two types of MBS to be blended is 2 to 4 parts by weight based on the balance between the impact resistance and the heat resistance of the produced pipe.
