Description

열차폐 성능이 향상된 합성수지 조성물 및 그 제조방법 {SYNTHETIC RESIN COMPOSITION WITH IMPROVED THERMAL BARRIER PERFORMANCE AND MANUFACTURING METHOD THEREOF}Synthetic resin composition with improved thermal barrier performance and manufacturing method thereof

본 발명은 열차폐 성능이 향상된 합성수지 조성물 및 그 제조방법에 관한 것으로, 더욱 상세하게는 가시광선 투과율이 높아 시인성이 확보되면서도 적외선 차단율이 높아 우수한 열차폐 성능을 나타내는 열차폐 성능이 향상된 합성수지 조성물 및 그 제조방법에 관한 것이다.The present invention relates to a synthetic resin composition with improved thermal shielding performance and a method for manufacturing the same, and more particularly, to a synthetic resin composition with improved thermal shielding performance exhibiting excellent thermal shielding performance due to high infrared blocking rate while ensuring visibility due to high visible light transmittance and its manufacturing method It relates to a manufacturing method.

일반적으로 열차폐 물질로 사용되는 무기산화물은 뛰어난 내구성과 높은 열차단 특성을 가지고 있지만, 낮은 가시광선 투과율 때문에 그 활용 범위가 한정 되어 있다. 무기산화물에는 안티몬틴옥사이드(ATO), 인듐틴옥사이드(ITO), 2산화실리카(SiO2), 3산화알루미나(Al2O3), 3산화몰리브덴(MoO3), 5산화니오브(Nb2O5), 5산화 바나듐(V2O5) 및 텅스텐 브론즈(Tungsten Bronze) 등이 사용되고 있는데, 이중 특히 가장 많이 사용되며 실제로 적외선 차단 특성이 양호한 무기산화물로는 안티몬틴옥사이드(ATO), 인듐틴옥사이드(ITO)와 텅스텐 브론즈(Tungsten Bronze) 등이 있다.Inorganic oxides, which are generally used as thermal barrier materials, have excellent durability and high thermal barrier properties, but their application range is limited due to low visible light transmittance. Inorganic oxides include antimontin oxide (ATO), indium tin oxide (ITO), silica dioxide (SiO 2 ), alumina trioxide (Al 2 O 3 ), molybdenum trioxide (MoO 3 ), niobium pentoxide (Nb 2 O) 5 ), vanadium pentoxide (V 2 O 5 ) and tungsten bronze are used, among which, among them, antimontin oxide (ATO) and indium tin oxide are the most commonly used inorganic oxides with good infrared blocking properties. (ITO) and Tungsten Bronze.

ATO는 ITO 보다 가격이 저렴하여 일반적으로 가시광선 투과율을 요하는 열차단 필름에 많이 사용되고 있다. 하지만 근적외선 흡수 특성이 1500nm에서 흡수를 시작하고 2000nm 까지 경사를 보이는 그래프로, 완벽한 적외선 차단이 이루어지지 못하고 있다. 즉 높은 가시광선을 나타내기 위해서는 그 투입량이 한정 되어진다. 만약 높은 근적외선을 나타내기 위해서 충진량을 많게 한다면, 가시광선은 40~50%로 현저히 떨어지게 되고, 과도한 무기물 함유는 열차단 코팅층의 2차 문제점(코팅층: 크랙, 부착력 저하, 백탁, 경시변화) 등을 일으킨다. 이렇듯 입자크기 10~20nm 의 ATO라고 해도 가시광선 대비 근적외선 차단 특성은 그 한계를 가지고 있어 활용 범위 및 고성능 열차단 필름 제조에는 사용되지 못하는 문제점이 있었다.ATO is cheaper than ITO, so it is commonly used in thermal barrier films requiring visible light transmittance. However, as the near-infrared absorption characteristic starts at 1500 nm and shows a slope up to 2000 nm, perfect infrared blocking is not achieved. That is, in order to display high visible light, the input amount is limited. If the amount of filling is increased to show high near-infrared rays, visible light is significantly reduced to 40-50%, and excessive inorganic content causes secondary problems of the thermal barrier coating layer (coating layer: cracks, reduced adhesion, white turbidity, change with time), etc. causes As such, even with ATO with a particle size of 10-20 nm, the near-infrared blocking property compared to visible light has its limitations, so it has a problem that it cannot be used in the production range and high-performance heat-blocking film.

도 1은 본 발명에 따른 열차폐 성능이 향상된 합성수지 조성물의 제조방법을 나타낸 순서도이다.1 is a flowchart showing a method of manufacturing a synthetic resin composition with improved thermal barrier performance according to the present invention.

이하에는, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.Hereinafter, a preferred embodiment of the present invention and the physical properties of each component will be described in detail, which is intended to describe in detail enough that a person of ordinary skill in the art to which the present invention pertains can easily carry out the invention, This does not mean that the technical spirit and scope of the present invention is limited.

본 발명에 따른 열차폐 성능이 향상된 합성수지 조성물은 고분자 수지, 열차폐제 및 첨가제로 이루어지며, 고분자 수지 60 내지 98.9 중량%, 열차폐제 1 내지 30 중량% 및 첨가제 0.1 내지 10 중량%로 이루어지는 것이 바람직하다.The synthetic resin composition with improved heat shielding performance according to the present invention consists of a polymer resin, a heat shielding agent, and an additive, and preferably comprises 60 to 98.9 wt% of a polymer resin, 1 to 30 wt% of a heat shielding agent, and 0.1 to 10 wt% of an additive .

상기 고분자 수지는 60 내지 98.9 중량%가 함유되며, 본 발명에 따른 열차폐 성능이 향상된 합성수지 조성물의 주재료가 되는 성분으로, 폴리에스터, 폴리에틸렌, 폴리프로필렌, 폴리이미드, 아크릴 및 폴리아미드로 이루어진 그룹에서 선택된 하나로 이루어지는 것이 바람직하다.The polymer resin is contained in an amount of 60 to 98.9% by weight, and is a main material of the synthetic resin composition with improved thermal barrier performance according to the present invention, from the group consisting of polyester, polyethylene, polypropylene, polyimide, acryl and polyamide. It is preferable to consist of a selected one.

상기의 성분으로 이루어지는 고분자 수지는 상기 열차폐제와의 상용성이 우수할 뿐만 아니라, 가시광선 투과율이 높아 투명성을 요하는 기술분야에 주로 적용될 수 있다.The polymer resin composed of the above components not only has excellent compatibility with the heat shielding agent, but also has high visible light transmittance, and thus can be mainly applied to technical fields requiring transparency.

상기 고분자 수지의 함량이 60 중량% 미만이면 합성수지 조성물의 기계적 물성이 저하될 수 있으며, 상기 고분자 수지의 함량이 98,9 중량%를 초과하게 되면 상대적으로 열차폐제의 함량이 지나치게 줄어들기 때문에 열차폐 효과가 저하될 수 있다.If the content of the polymer resin is less than 60% by weight, mechanical properties of the synthetic resin composition may be lowered, and if the content of the polymer resin exceeds 98,9% by weight, the content of the thermal barrier agent is relatively reduced because the heat shielding agent is excessively reduced. effectiveness may be reduced.
