Description
본 발명은 화강석 무늬를 갖는 강화 플라스틱 및 그 제조방법에 관한 것으로, 특히 일반 암석이나 화강석과 같은 천연광물을 모조한 표면이 구성될 수 있고, 다양한 색상의 표현이 가능하고 인장강도와 휨강도 및 압축강도가 높아 박판재로의 생산이 가능한 강화 플라스틱 및 그 제조방법에 관한 것이다.The present invention relates to a reinforced plastic having a granite pattern and a method of manufacturing the same, and in particular, a surface imitated with natural minerals such as general rock or granite can be formed, capable of expressing various colors, tensile strength, bending strength and compressive strength. It relates to a high-strength plastic and a method of manufacturing the same that can be produced in a thin sheet material.
일반적으로, 암석의 무늬를 갖는 많은 모조 경화제품이 소개되어 있으나, 이러한 모조 경화제품은 단순히 합성수지에 안료 등을 혼합하여 경화시켜 제품을 얻고 있었기 때문에 그 무늬나 질감이 단순하였고, 또한 강도가 저하되어 박판으로 제조하기 곤란하였던 것이다.In general, many imitation cured products having a pattern of rock have been introduced, but since the imitation cured product was obtained by simply mixing a pigment or the like with a synthetic resin to obtain a product, the pattern or texture was simple, and the strength was also reduced. It was difficult to manufacture a thin sheet.
특히, 박판으로 성형될 경우에는 강도를 보강할 수 있는 성분이 결여되어 경화된 제품에서 파손, 균열이 발견되는 등의 문제점이 유발되었던 것이다.In particular, when molded into a thin plate is lacking a component capable of reinforcing strength, causing problems such as breakage, cracks are found in the cured product.
한편, 종래에는 상기와 같은 모조 경화 성형물의 성형에 고가의 형틀이 사용되고 있었기 때문에 형틀이 손상될 경우 이를 보수하거나 교체하는데 많은 비용이 소요되는 경제적 손실이 발생하는 문제점이 있었다.On the other hand, in the related art, since the expensive mold was used for molding the above-mentioned imitation cured molding, there was a problem in that an economic loss occurs that requires a large cost to repair or replace the mold when the mold is damaged.
본 발명은 상기와 같은 종래기술의 문제점을 해소하기 위하여 안출한 것으로, 본 발명의 기술적 과제는 화강석과 같은 천연광물의 무늬와 다양한 색상의 등의 표현이 가능하고, 인장강도와 휨강도 및 압축강도가 높아 박판재로의 생산이 가능한 화강석 무늬를 갖는 강화 플라스틱을 제공하는데 있다.The present invention has been made in order to solve the problems of the prior art as described above, the technical problem of the present invention is capable of expressing the pattern and various colors of natural minerals such as granite, tensile strength and bending strength and compressive strength It is to provide a reinforced plastic having a granite pattern which can be produced as a thin plate material.
본 발명의 다른 기술적 과제는 화강석 무늬를 갖는 강화 플라스틱을 제조함에 있어서, 신속한 생산 사이클로 생산성을 향상시킬 수 있고, 형틀의 손상을 최소화하여 비용을 절감할 수 있는 제조방법을 제공하는데 있다.Another technical problem of the present invention is to provide a manufacturing method capable of improving productivity by a rapid production cycle and minimizing damage to a mold in manufacturing reinforced plastic having a granite pattern.
