Abstract
Description
본 발명은 사출성능이 개선된 폴리 비닐 클로라이드(PVC) 수지 조성물에 관한 것으로, 보다 상세하게는 PVC 레진에 가소제 등의 첨가제를 적절한 조성비로 함으로써 사출성형의 적당한 재료로 하는데 있다.The present invention relates to a polyvinyl chloride (PVC) resin composition with improved injection performance, and more particularly, to an appropriate material for injection molding by adding an additive such as a plasticizer to PVC resin in an appropriate composition ratio.
일반적으로 PVC수지는 투명하고, 본래는 열경화성 수지이지만, 연화시키는 성분 즉 가소제를 첨가하면 부드러운 제품을 만들 수 있다. 이러한 제품을 연질 PVC수지 제품이라 부르고, 필름, 시트, 레자 등을 만들 수 있다. 이에 비하여 가소제를 첨가하지 않은 것은 경질 PVC수지 제품이라 부르고, 관연결구, 관, 판재 등을 만들고 있다.In general, PVC resin is transparent and inherently thermosetting resin, but softening component, that is, plasticizer can be added to make a soft product. These products are called soft PVC resin products and can be made into films, sheets, leather, and the like. On the other hand, plasticizers are not added, which is called a hard PVC resin product, and pipes, pipes, and boards are made.
또한, PVC수지는 내열성을 결핍하고 있어 안정성을 부여하기 위하여 안정제를 첨가하고 있다. 그 외에 윤활제나 안료와 같은 첨가제를 넣어 성형가공성을 대폭 증가시키고 있다.In addition, PVC resin lacks heat resistance and a stabilizer is added to impart stability. In addition, additives such as lubricants and pigments are added to greatly increase the molding processability.
특히 합성 바닥재(synthetic flooring)는 광범위하게 상업적으로 사용되어 왔고, 모든 종류의 수지류 또는 수지류의 혼합물로 구성된 다양한 바닥재 조성물들로부터 만들어진다. 그 중에서도 PVC(폴리비닐클로라이드와 폴리비닐클로라이드의 공중합체)는 바닥재 물질(flooring materials)에서 광범위하게 사용되고, 현재 많은 합성 바닥재 조성물들의 주요 성분이다.Synthetic flooring in particular has been widely used commercially and is made from various flooring compositions consisting of all kinds of resins or mixtures of resins. Among them, PVC (copolymer of polyvinylchloride and polyvinylchloride) is widely used in flooring materials and is now a major component of many synthetic flooring compositions.
바닥재 물질로 사용되는 PVC조성물들은 다른 물질들과 함께 채워지거나 펼쳐지며 PVC는 물질들을 함께 결합시키는 결합재(binder)로서 작용한다. PVC조성물은 보통 상당량의 충전제를 함유하고, 충전제들은 당 기술분야에서 잘 알려져 있으며, 일반적으로 예를 들면 점토(clay), 운모(talc), 탄산칼슘, 황산바륨, 규산염 (silicate), 삼수화알루미늄(aluminum trihydrate)과 같은 무기물질들이다.PVC compositions used as flooring materials are filled or unrolled with other materials and PVC acts as a binder to bond the materials together. PVC compositions usually contain a significant amount of fillers, and fillers are well known in the art and generally include, for example, clay, talc, calcium carbonate, barium sulfate, silicate, aluminum trihydrate inorganic materials such as aluminum trihydrate.
PVC는 또한 가소제, 착색제, UV-안정화제(UV-stabilizers), 정전기 방지제 (antistatic agents), 열안정제(thermal stabilizers)와 같은 통상의 첨가제들을 함유하고 있으며, 양적으로 안정된 그들의 기능을 위하여 사용되는 내염제(flame retardants)는 당기술 분야에 알려져 있다.PVC also contains common additives such as plasticizers, colorants, UV-stabilizers, antistatic agents, thermal stabilizers, and is used for their quantitatively stable functions. Flame retardants are known in the art.
그러나, 위와 같은 PVC수지로 판재를 사출성형을 할 경우 가소제, 안정화제, 열안정화제, 결합제, 충진제 등의 조성비가 적당하지 않으면 판재가 제대로 성형이 되지 않거나, 사출 성형시 판재 내부에 기공이 다수 존재하여 표면에 핀홀가 같은 불량이 발생하고, 표면에 크랙이 가는 등 문제가 있었다.However, when the injection molding of the plate with the PVC resin as described above, if the composition ratio of the plasticizer, stabilizer, heat stabilizer, binder, filler, etc. is not suitable, the plate is not molded properly, or there are many pores inside the plate during injection molding. There existed problems, such as a pinhole on the surface and cracks on the surface.
본 발명은 위와 같은 문제점을 해결하기 위해 안출한 것으로서, 본 발명의 목적은 PVC수지로 판재를 사출성형을 할 경우 가소제, 안정화제, 열안정화제, 결합제, 충진제 등의 조성비를 최적으로 하여 판재의 사출 성형성을 대폭 향상시키면서도 제품의 표면에 핀홀이나 크랙과 같은 손상이 없도록 하면서도 인장강도, 내마모성등의 기계적 성질을 향상시키는데 있다.The present invention has been made to solve the above problems, the object of the present invention is to optimize the composition ratio of the plasticizer, stabilizer, heat stabilizer, binder, filler, etc. when the injection molding of the plate with PVC resin While greatly improving the injection moldability, it is possible to improve mechanical properties such as tensile strength and abrasion resistance while preventing damage such as pinholes or cracks on the surface of the product.
