Description
본 발명은 항균성 및 중금속 흡착력의 효과를 갖는 폴리염화비닐수지관의 제조용수지조성물 및 그로부터 제조되는 폴리염화비닐수지관에 관한 것으로서 보다 상세하게는 탄산칼슘과 스코리아를 혼합하여 세균이나 곰팡이의 번식을 억제하고 오염된 공기를 정화시키며 중금속 흡착력을 갖는 항균성 및 중금속 흡착력의 효과와 압출부하가 저감되고 성형성이 용이하여 생산성이 향상되도록 한폴리염화비닐수지관의 제조용수지조성물 및 그로부터 제조되는 폴리염화비닐수지관에 관한 것이다.The present invention relates to a resin composition for producing a polyvinyl chloride resin tube having an effect of antimicrobial activity and heavy metal adsorption capacity, and a polyvinyl chloride resin tube produced therefrom. More specifically, it is possible to suppress the propagation of bacteria or fungi by mixing calcium carbonate and sea Korea. Resin composition for manufacturing polyvinyl chloride resin tubes and polyvinyl chloride water produced therefrom to purify contaminated air, to improve the productivity of antibacterial and heavy metal adsorption force with heavy metal adsorption capacity, and to reduce extrusion load and to increase moldability. It is about branch office.
통상의 주철관, 동관 등은 그 과중한 무게로 인하여 작업성의 저하, 산화 및 부식에 의한 통수능력 감소, 적수 및 백수 현상으로 인한 상수도물의 오염 등과 같은 결함을 갖고 있으며, 그에 따라 염화비닐수지로 만들어진 염화비닐수지관이 빠르게 수도관으로 대체되어 사용되고 있는 추세이다.Ordinary cast iron pipes, copper pipes, etc. have defects such as deterioration of workability due to their heavy weight, reduction of water permeability due to oxidation and corrosion, contamination of tap water due to red water and white water phenomenon, and accordingly, vinyl chloride made of vinyl chloride resin. Resin pipes are rapidly being replaced by water pipes.
한편, 내식성, 경량에 기한 높은 작업효율성에도 불구하고 염화비닐수지관은 비록 경질의 염화비닐수지로 만들어진다고 해도 내충격성이 약하여 외압에 의해 쉽게 파손된다는 문제점이 있다. On the other hand, in spite of high work efficiency due to corrosion resistance and light weight, the vinyl chloride resin tube has a problem that even if it is made of hard vinyl chloride resin, the impact resistance is weak and easily broken by external pressure.
상기 염화비닐수지관은 그 재질의 특성상 첨가제 등을 보강하여 내충격성을 높이면 인장강도 및 편평하중강도가 낮아지고, 인장강도 및 편평하중 강도를 높이면 내충격성이 낮아지는 역비례관계를 가지고 있어 물성개선에 난점이 있다.The vinyl chloride resin tube has an inverse relationship with lowering the tensile strength and the flat load strength when the impact resistance is enhanced by reinforcing additives and the like, and the impact resistance is decreased when the tensile strength and the flat load strength are increased. There is a difficulty.
또한 충격보강제로서 염소화폴리에틸렌수지(CPE ; Chlorinated Polyethylene, 이하 ‘CPE'라 한다), 폴리메틸메타크릴레이트-부타디엔-스티렌수지(MBS ; methylmethacrylate-Butadien-Styrene terpolymer , 이하 ’MBS'라 한다), 아크릴수지 등이 사용되고 있으나, 아크릴수지는 장기간의 내후성이 요구되는 플라스틱 창호재 전용 충격보강제로서 일반 파이프 첨가제와의 호환성이 없어서 적절치 못하며, MBS계 충격보강제와 CPE계 충격보강제가 일반 파이프 첨가제로 사용되고 있다.In addition, as impact modifiers, chlorinated polyethylene resin (CPE; Chlorinated Polyethylene (hereinafter referred to as 'CPE'), polymethyl methacrylate-butadiene-styrene resin (MBS; methylmethacrylate-Butadien-Styrene terpolymer (hereinafter referred to as 'MBS'), acrylic Although resins and the like are used, acrylic resin is an impact modifier for plastic windows and doors requiring long-term weather resistance, which is not suitable because it is incompatible with general pipe additives, and MBS-based impact modifiers and CPE-based impact modifiers are used as general pipe additives.
한편, 폴리염화비닐을 주재료로 하는 파이프의 제조에서, 탄산칼슘이나 활석과 같은 무기충진제를 사용하지 않는 경우, 압출성형과 같은 성형에 있어서 압출부하가 증가하여 성형이 잘 되지 않는 등 성형성이 극히 저하되어 생산성이 저하되고, 저가의 무기충진제를 사용치 않고, 상대적으로 고가인 수지나 첨가제들을 사용 하여야 함에 따라 생산비가 상승하는 등의 문제점이 야기될 수 있어, 통상의 폴리염화비닐수지 파이프의 제조에서는 적어도 3중량부 정도의 무기충진제를 포함하는 것이 일반적이다.On the other hand, in the production of pipes mainly composed of polyvinyl chloride, when inorganic fillers such as calcium carbonate and talc are not used, the moldability is extremely high, such as the extrusion load increases due to the increase in extrusion load in molding such as extrusion molding. The lower the productivity, the lower the inorganic filler, and the use of relatively expensive resin or additives may cause problems such as increased production costs, the production of conventional polyvinyl chloride resin pipes In general, at least about 3 parts by weight of the inorganic filler is included.
본 발명은 상기한 종래 폴리염화비닐수지관의 문제점을 감안하여 안출한 것으로서 이의 목적은 세균이나 곰팡이의 번식을 억제하고 오염된 공기를 정화시키며 중금속 흡착력을 갖는 항균성 및 중금속 흡착력의 효과를 갖으며, 또한 압출부하가 저감되고 성형성이 용이하여 생산성이 향상되도록 한 폴리염화비닐수지관의 제조용수지조성물 및 그로부터 제조되는 폴리염화비닐수지관을 제공하는데 있다.The present invention has been made in view of the above problems of the conventional polyvinyl chloride resin tube, the object of which is to suppress the growth of bacteria or mold, purify the contaminated air, and has the effect of antibacterial and heavy metal adsorption capacity having a heavy metal adsorption capacity, Another object of the present invention is to provide a resin composition for producing a polyvinyl chloride resin tube, and a polyvinyl chloride resin tube manufactured therefrom, in which extrusion load is reduced and moldability is easily improved.

상기한 본 발명인 폴리염화비닐수지관 제조용수지조성물을 이용하는 폴리염화비닐수지관은 폴리염화비닐수지 70중량%-85중량%, 안정제 5중량%-8중량%, 충격보강제 4중량%-8중량%, 가공조제 3중량%-6중량%, 탄산칼슘 1중량%-3중량%, 스코리아(scoria) 2중량%-5중량%를 포함하여 이루어진 것에 특징이 있다.The polyvinyl chloride resin tube using the resin composition for producing the polyvinyl chloride resin tube of the present invention described above is 70% by weight-85% by weight of polyvinyl chloride resin, 5% by weight-8% by weight stabilizer, 4% by weight-8% by weight of an impact modifier , Processing aid 3% by weight-6% by weight, calcium carbonate 1% by weight-3% by weight, scoria 2% by weight-5% by weight.
이와 같은 본 발명은 세균이나 곰팡이의 번식을 억제하고 오염된 공기를 정화시키며 중금속 흡착력을 갖는 항균성 및 중금속 흡착력의 효과를 갖으며, 또한 압출부하가 저감되고 성형성이 용이하여 생산성이 향상되는 이점이 있다.The present invention has the advantage of inhibiting the growth of bacteria or mold, purifying the contaminated air, and has the effect of antibacterial and heavy metal adsorption power having a heavy metal adsorption capacity, and also improves productivity by reducing extrusion load and easy moldability have.
이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 세균이나 곰팡이의 번식을 억제하고 오염된 공기를 정화시키며 중금속 흡착력을 갖는 항균성 및 중금속 흡착력의 효과를 갖으며, 또한 압출부하가 저감되고 성형성이 용이하여 생산성을 향상시킨 수지조성물은 폴리염화비닐수지 70중량%-85중량%, 안정제 5중량%-8중량%, 충격보강제 4중량%-8중량%, 가공조제 3중량%-6중량%, 탄산칼슘 1중량%-3중량%, 스코리아(scoria) 2중량%-5중량%를 포함하여 이루어짐 구조이다.The resin composition which suppresses the growth of bacteria or molds, purifies the contaminated air, has the effect of antibacterial and heavy metal adsorption with heavy metal adsorption capacity, and improves productivity by reducing extrusion load and easy formability. 70% to 85% by weight of polyvinyl chloride resin, 5% to 8% by weight of stabilizer, 4% to 8% by weight of impact modifier, 3% to 6% by weight of processing aid, 1% to 3% by weight of calcium carbonate , S Korea (scoria) is a structure comprising a 2% by weight-5% by weight.
상기 조성에서 폴리염화비닐수지는 바람직하게는 중합도 700 내지 1,300의 범위 이내인 것이 사용될 수 있다. 상기 폴리염화비닐수지의 중합도가 800 미만으로 되는 경우, 충격강도 및 인장강도와 같은 기계적 물성이 저하되는 문제점이 있을 수 있고, 반대로 1,300을 초과하는 경우, 일반적인 가공온도에서 가공이 어려우 며, 가공온도를 높일 경우, 열안정성이 저하되는 문제점이 있을 수 있다.Polyvinyl chloride resin in the composition may preferably be used in the range of polymerization degree 700 to 1,300. When the degree of polymerization of the polyvinyl chloride resin is less than 800, there may be a problem that mechanical properties such as impact strength and tensile strength are lowered, on the contrary, when the polyvinyl chloride resin exceeds 1,300, it is difficult to process at a general processing temperature, processing temperature If it is increased, there may be a problem that the thermal stability is lowered.
상기 조성에서 탄산칼슘은 착색, 전기절연성, 내노화성, 열에 의한 팽창, 수축도 등의 조절을 목적으로 하여 첨가하는 일이 많으며 상기 탄산칼슘이 1중량% 미만으로 사용되는 경우, 열에 의한 팽창, 수축도가 높아지는 문제점이 있을 수 있고, 반대로 3중량%를 초과하는 경우, 열에 의한 팽창, 수축도가 높아지고 생산원가가 상승되는 문제점이 있을 수 있다.In the composition, calcium carbonate is often added for the purpose of controlling coloring, electrical insulation, aging resistance, thermal expansion, shrinkage, and the like, and when calcium carbonate is used in less than 1% by weight, thermal expansion and contraction There may be a problem that the degree is higher, on the contrary, if it exceeds 3% by weight, there may be a problem that the expansion and contraction degree due to heat is increased and the production cost is increased.
상기 조성에서 안정제는 폴리염화비닐수지가 열이나 빛에 대해서 안정성이 없기 때문에 가공할 때 및 제품화한 다음의 착색, 분해를 방지하는데 필요하며 상기 안정제가 5중량% 미만으로 사용되는 경우, 열안정성이 저하되어 가공 중에 탄화가 일어나는 문제점이 있을 수 있고, 반대로 8중량%를 초과하는 경우, 충격강도가 저하되고, 생산원가가 상승되는 문제점이 있을 수 있다.In this composition, the stabilizer is necessary to prevent coloring and decomposition after processing and after commercialization since the polyvinyl chloride resin is not stable to heat or light, and when the stabilizer is used at less than 5% by weight, There may be a problem that the carbonization occurs during the processing is lowered, on the contrary, if it exceeds 8% by weight, impact strength is lowered, there may be a problem that the production cost is increased.
상기 조성에서 스코리아(scoria)는 거무스름한 다공질(多孔質)의 염기성 화산분출물로서 암재(岩滓)라고도 한다. 스코리아는 암흑색, 흑회색, 갈색, 적색 등으로 요철이 많은 불규칙한 암괴를 이루고 있으며, 다공질이기 때문에 비중은 작다. 이러한 스코리아는 천연상태에서 원적외선 방사 92~93중량%, 탈취율 97중량%, 향균 곰팡이 99.9중량%의 대장균을 퇴치하는 성능을 가진 천연 소재로서 근간에 많이 사용되고 있는 옥, 황토, 맥반석, 게르마늄 등에 비하여 원적외선 방사량 등에 있어서 월등한 것으로 입증되고 있다.In this composition, scoria is a blackish, porous basic volcanic eruption, also called rock material. SKOREA forms irregular rocks with many irregularities such as dark black, black gray, brown, and red, and its specific gravity is small because it is porous. Such Korea is a natural material that has the ability to combat E. coli of 92-93% by weight of far-infrared radiation, 97% by weight of deodorization, and 99.9% by weight of antibacterial fungus in its natural state, compared to jade, loess, elvan, germanium, etc. It is proven to be superior in radiation dose and the like.
상기 스코리아는 화학적 성분 분석결과 인체에 유해한 성분은 전혀 없으며 수은이나 납 같은 중금속을 흡착하는 성분이 매우 우수하며 표 1에는 색깔별로 본 스코리아의 화학분석 및 특성이 나타나 있다.As a result of analyzing the chemical composition, there is no harmful component to the human body, and the component that adsorbs heavy metals such as mercury or lead is very excellent. Table 1 shows the chemical analysis and characteristics of this Korea by color.

상술한 바와 같이, 스코리아는 각종 분야에서 다양한 효과를 얻을 수 있으며, 특히 다공질이라는 특성으로 인하여 오염물질의 정화능력이 탁월함을 알 수 있다.As described above, SKOREA can obtain various effects in various fields, and in particular, it can be seen that the purification ability of pollutants is excellent due to the characteristics of porous material.
상기 조성에서 충격보강제는 경질제품에 고무상 탄성을 가진 고분자물 4~8중량%를 첨가하여 내충격성을 개질할 수가 있다. 특히 첨가량이 5~6중량%의 사이에서 뚜렷한 효과를 볼 수 있다. 상기 충격보강제가 4중량% 미만으로 사용되는 경우, 충격강도가 저하되는 문제점이 있을 수 있고, 반대로 8중량%를 초과하는 경우, 압출부하가 높아지고, 생산원가가 상승되는 문제점이 있을 수 있다.In the above composition, the impact modifier may modify the impact resistance by adding 4 to 8% by weight of a polymer having rubbery elasticity to the hard product. In particular, a distinct effect can be seen between 5 to 6% by weight. When the impact modifier is used in less than 4% by weight, there may be a problem that the impact strength is lowered, on the contrary, if the impact modifier exceeds 8% by weight, the extrusion load is high, there may be a problem that the production cost is increased.
상기 조성에서 가공조제는 수득되는 조성물의 압출성형 시 성형성을 향상 시키기 위함과 동시에 염화비닐수지 메트릭스에의 염화비닐-에틸렌비닐아세테이트(VC-EVA) 공중합체의 혼합을 강화하는 목적으로 사용된다.The processing aid in the above composition is used for the purpose of enhancing the formability during extrusion molding of the obtained composition and at the same time to enhance the mixing of the vinyl chloride-ethylene vinyl acetate (VC-EVA) copolymer into the vinyl chloride resin matrix.
상기 가공조제가 3중량% 미만으로 사용되는 경우, 가공조제의 효과가 나타나지 않게 되는 문제점이 있을 수 있고, 반대로 6중량%를 초과하는 경우, 압출부하가 높아지고, 생산원가가 상승되는 문제점이 있을 수 있다.When the processing aid is used in less than 3% by weight, there may be a problem that the effect of the processing aid does not appear, on the contrary, if it exceeds 6% by weight, the extrusion load is high, there may be a problem that the production cost is increased have.
