The polyvinyl chloride resin composition for fluid pipes and joint pipes according to the present invention is characterized by containing polymer rubber impregnated calcined diatomaceous earth as an impact modifier.
규조토(diatomaceous earth)는 규조라 불리는 수중 단세포 식물의 잔해가 해저(海底)나 호저(湖底)에 퇴적한 집합체로 일종의 화석토이다. 규조는 수중환경에서 실리카를 추출해내어 자신의 단단한 골격 구조를 구성하는 능력이 있는데, 규조 골격의 퇴적물이 속성 작용을 받아 굳어져 형성된 규조토 퇴적암은 대부분이 함수 비정질 실리카로 이루어져 있으며 대규모 응집상태로 산출된다. 규조토는 퇴적된 장소에 따라 담수성과 해수성으로 구분되며 이에 따른 물리적 특성의 차이도 보이게 된다. 규조토는 약 86 ~ 93%의 실리카를 함유한 다공성 구조로, 녹는점이 1400℃이상이고, 일반적인 물리 화학작용에 안정적이다. Diatomaceous earth is a type of fossil soil in which debris of aquatic single-celled plants called diatoms is deposited on the seabed or the bottom of the sea. Diatoms are capable of extracting silica from the underwater environment and constructing their own solid framework. Diatomite sedimentary rocks formed by the sedimentation of the diatomaceous skeleton due to its rapid action are mostly composed of hydrous amorphous silica and are produced in large-scale aggregated state. . Diatomaceous earth is divided into freshwater and seawater according to the place where it is deposited. Diatomaceous earth is a porous structure containing about 86 ~ 93% silica, melting point is more than 1400 ℃, stable to general physical chemistry.

The calcined diatomaceous earth used in the present invention is a porous material in which diatomaceous earth particles are grown at the same time as organic matter is removed through a firing process using a rotary kiln of 800 to 1200 ° C. There is a good feature. Such calcined diatomaceous earth is commercially available, and examples thereof include luna white and celite.
본 발명에 따르는 고분자 러버 함침 소성 규조토는 당분야에서 내충격제로 잘 알려진 고분자 러버를 소성 규조토에 함침시킨 입자상의 물질이다. The polymeric rubber impregnated calcined diatomaceous earth according to the present invention is a particulate matter impregnated with calcined diatomaceous earth, which is a polymer rubber well known in the art as an impact agent.
본 발명에 따라 고분자 러버 함침 소성 규조토를 배합하면 종래에 비해 감소된 고분자 러버 함량에서 충분한 내충격 개질효과를 얻을 수 있게 된다.When the polymer rubber impregnated calcined diatomaceous earth is blended according to the present invention, a sufficient impact resistance effect can be obtained at a reduced polymer rubber content as compared with the conventional art.
또한 다공성의 고분자 러버 함침 소성 규조토를 배합한 본 발명의 유체파이프 및 이음관용 폴리염화비닐 수지 조성물로 하수관에 적용한 경우에는 슬러지 제거효과를 기대할 수 있으며, 수도관에 적용한 경우에는 정수효과를 기대할 수 있다. In addition, when applied to the sewage pipe with a polyvinyl chloride resin composition for fluid pipe and joint pipe of the present invention containing porous polymer rubber impregnated calcined diatomaceous earth can be expected sludge removal effect, when applied to the water pipe can be expected water purification effect.
본 발명에서 고분자 러버는 당분야에 잘알려진 통상의 것을 사용할 수 있으며, 그중에서도 특히 바람직한 예로는 (메트)아크릴레이트-부타디엔-스티렌 러버, 아크릴로니트릴-부타디엔-스티렌 러버, (메트)아크릴레이트 러버, 클로리네이티드 폴리에틸렌 러버, 에틸렌-비닐 아세테이트 러버가 있다. 이러한 고분자 러버는 단독 또는 2종 이상 혼합하여 소성 규조토에 함침시킬 수 있다. In the present invention, the polymer rubber may be used a conventional one well known in the art, and particularly preferred examples thereof include (meth) acrylate-butadiene-styrene rubber, acrylonitrile-butadiene-styrene rubber, (meth) acrylate rubber, Chlorinated polyethylene rubber, ethylene-vinyl acetate rubber. These polymer rubbers may be impregnated with calcined diatomaceous earth alone or by mixing two or more kinds.
본 조성물에서 고분자 러버 함침 소성 규조토의 함량은 폴리염화비닐 레진 100중량부에 대하여 1~20 중량부, 보다 바람직하게 3~15중량부이다. 상기 함량이 1 중량부 보다 적은 경우에는 내충격 개질효과가 미흡하고, 20중량부 보다 많은 경우에는 유체파이프나 이음관과 같은 제품의 성형성이 다소 미흡하게 되어 상기한 범위내의 함량으로 배합하는 것이 바람직하다. The content of polymeric rubber-impregnated calcined diatomaceous earth in the present composition is 1-20 parts by weight, more preferably 3-15 parts by weight, based on 100 parts by weight of polyvinyl chloride resin.

Do.
또한, 고분자 러버 함침 소성 규조토에서 소성 규조토와 고분자 러버의 구성비는 소성 규조토 10~50중량%의 고분자 러버 50~90중량%가 바람직하다. 상기 구성비에서 소성 규조토의 함량이 너무 적으면 내충격 개질효과가 다소 미흡하고 너무 많으면 탄성이 다소 미흡하게 되므로 상기한 범위의 구성비로 소성 규조토에 고분자 러버를 함침하여 제조하는 것이 바람직하다. In the polymer rubber impregnated calcined diatomaceous earth, the composition ratio of calcined diatomaceous earth and the polymer rubber is preferably 50 to 90 wt% of the polymer rubber of 10 to 50 wt% calcined diatomaceous earth. If the content of calcined diatomaceous earth in the composition ratio is too small, the impact resistance effect is somewhat insufficient and the elasticity is slightly insufficient if too much, it is preferable to manufacture by impregnating the polymer rubber in the calcined diatomaceous earth in the above-described composition ratio.

내충격 개질제로 실시예 2와 동량의 메타크릴레이트-부타디엔-스티렌 러버를 사용한 것을 제외하고는 실시예 2와 동일한 절차를 반복하여 폴리염화비닐 수지 조성물을 제조하였다.The same procedure as in Example 2 was repeated except that the same amount of methacrylate-butadiene-styrene rubber was used as the impact modifier to prepare a polyvinyl chloride resin composition.
상기 실시예 및 비교예의 조성물로 ASTM D256 규격에 따라 시편을 제조한 후 다음과 같은 방법으로 상온충격강도와 저온 충격강도를 측정하였다 그 결과는 표 1에 제시된다. After the specimen was prepared according to the ASTM D256 standard with the composition of the Examples and Comparative Examples, the room temperature impact strength and the low temperature impact strength were measured by the following method. The results are shown in Table 1.
* 상온 충격강도(단위: Kg?cm/cm): 시편을 23℃에서 24시간동안 방치한 다음 Tinus Olsen 사의 892 Model 충격강도 평가기에 5.4J의 추를 장착한 후 측정.* Impact strength at room temperature (unit: Kg? Cm / cm): The specimen was allowed to stand at 23 ° C for 24 hours and then measured after installing a weight of 5.4J on Tinus Olsen's 892 Model Impact Strength Evaluator.
* 저온 충격강도(단위: Kg?cm/cm): 시편을 OZONE 사의 저온챔버에 -10℃에서 3시간이상 방치한 다음 Tinus Olsen 사의 892 Model 충격강도 평가기에 2.7J의 추를 장착한후 측정.* Low temperature impact strength (unit: Kg? Cm / cm): The specimen was placed in the low temperature chamber of OZONE at -10 ℃ for 3 hours or longer, and then measured by installing 2.7J weight on Tinus Olsen's 892 Model impact strength evaluator.
또한, 실시예의 조성물로 하수관용 유체파이프를 제작한 후, KS M 3401 규격에 따라 인장강도, 비카트 연화온도, 낙추충격, 침지시험, 편평시험 등을 행하였다, 그 결과는 표 2 및 3에 제시된다. In addition, after producing the fluid pipe for sewage pipes using the composition of the Example, tensile strength, vicat softening temperature, fall impact, immersion test, flat test and the like according to the KS M 3401 standard, the results are shown in Tables 2 and 3 Presented.
상기한 실험결과로부터 고분자 러버를 그대로 사용하는 폴리염화비닐 조성물에 비해 본 발명에 따라 고분자 러버 함침 소성 규조토를 사용하는 폴리염화비닐 조성물이 훨씬 향상된 내충격성을 나타냄을 알 수 있으며, 또한 유체파이프의 제조에 적합한 특성을 만족하는 것을 알 수 있다. From the above experimental results, it can be seen that the polyvinyl chloride composition using the polymer rubber-impregnated diatomaceous earth exhibits much improved impact resistance compared to the polyvinyl chloride composition using the polymer rubber as it is. It can be seen that it satisfies the characteristics suitable for.
이상에서 설명한 본 발명은 전술한 설명에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다. The present invention described above is not limited to the above description, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be obvious to you.
