본 발명의 상기한 충진제(Filler)는 통상의 고분자 합성시에 사용되는 통상의 충진제를 사용할 수 있으며, 실리콘고무의 표면 터치 및 난연 특성을 보강, 조절하기 위하여 실리카, 탄산칼슘, 실리카 비드, 우레탄 비드, MMA(MethylMetaAcrylate)비드, 알루미늄하이드레이트(Alumina hydrate), 티타늄다이옥사이드(Titanium dioxide), 유기인산에스테르화합물, 지방족유기산금속염, 하이드로탈 사이트(hydrotalcite), 분말규산 등을 0.1~30 중량부를 혼합하여 실리콘 코팅액을 제조하여 이용하는 것이 바람직하다. 또한 색상 구현을 위해서 실리콘 안료를 사용할 수 있으며, 완제품의 용도 및 고객 요구 특성에 따라서 적합한 특성을 가지는 실리콘 코팅액을 선정 제조할 수 있다. The filler (Filler) of the present invention can use a conventional filler used in the synthesis of conventional polymers, silica, calcium carbonate, silica beads, urethane beads in order to reinforce and control the surface touch and flame retardant properties of silicone rubber , MMA (MethylMetaAcrylate) bead, aluminum hydrate, titanium dioxide, organic phosphoric acid ester compound, aliphatic organic metal salt, hydrotalcite, powder silicic acid, etc. are mixed with 0.1 to 30 parts by weight of a silicone coating solution It is preferable to prepare and use it. In addition, a silicone pigment can be used for color realization, and a silicone coating solution having suitable properties can be selected and manufactured according to the use of the finished product and the characteristics required by customers.

이러한 가공 방법(도1)으로 제조되는 실리콘 선루프용 블라인드의 경우는 표 1에서 볼 수 있듯이 자동차용 소재의 시험 방법을 접목하여 시험 진행을 하였으며;In the case of the silicone sunroof blind manufactured by this processing method (Fig. 1), as shown in Table 1, the test was carried out by grafting the test method of the material for automobiles;

내한성(저온안정성), 열노화성(내열성), 난연성, 내광견뢰도(내광성), 접착력이 우수할 뿐 아니라, 실리콘 소재 특성이 부여되어 블랙원단 사용으로 나타날 수 있는 염료의 이염현상을 방지할 수 있는 고물성의 실리콘 고무가 적용된 자동차 선루프용 블라인드를 제조할 수 있게 되었다.It has excellent cold resistance (low temperature stability), heat aging resistance (heat resistance), flame retardancy, light fastness (light resistance), and adhesion. It became possible to manufacture blinds for car sunroofs to which the physical properties of silicone rubber were applied.

이렇게 제조된 자동차 선루프용 블라인드 제품는 기존 소재(용액형 PU 또는 핫멜트 방식 등)로 제조된 제품과 차별화된 물성을 확보할 뿐 아니라, 연속 공정으로 보다 경제성이 있는 제품을 제조할 수 있고 각종 인테리어 용도로의 응용 확대를 기대할 수 있다.The blind products for automobile sunroofs manufactured in this way not only secure physical properties differentiated from products manufactured with existing materials (solution type PU or hot melt method, etc.) It can be expected to expand its application to
