Description
본 발명은 폴리에스테르 스판본드 발포벽지의 제조방법에 관한 것으로 상세하게는 발포제의 거품형태유지성과 내수성 및 강도가 우수하며 시공시 풀흡수량이 적은 발포벽지의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester spanbond foam wallpaper, and more particularly, to a method for manufacturing a foam wallpaper having excellent foam form retention, water resistance and strength, and a small amount of water absorption during construction.
종래에는 종이에 날염을 한 벽지가 대부분이었으나, 최근에는 생활수준의 향상에 따라 종이와 단섬유 부직포의 합포지에 염화비닐 또는 아크릴 발포제를 처리하여 발포시킴으로서 볼륨감과 심미성을 부여한 발포벽지가 개발되어 판매되고 있다.In the past, most of the wallpaper printed on the paper, but in recent years, according to the improvement of the standard of living, foamed wallpaper that gives volume and aesthetics is developed and sold by treating and foaming vinyl chloride or acrylic foaming agent on the paper and short fiber nonwoven fabric. have.
그러나 종전의 발포벽지는 단섬유 부직포만으로는 발포가 되지 않기 때문에 부직포에 종이를 합포한 다음 종이위에 염화비닐발포체 또는 아크릴발포체를 처리하여 발포시킨 것이다.However, conventional foam wallpaper is foamed by treating the vinyl chloride foam or acrylic foam on the paper after laminating the paper to the nonwoven fabric because only the single fiber nonwoven fabric is not foamed.
그러나 상기한 발포벽지는 사용되는 부직포가 친수계 단섬유 부직포이므로 벽지시공시에 기존의 종이벽지에 비하여 풀사용량이 3배정도 증가되고 종이와 합포한 것이기 때문에 합포속도가 느려 생산성이 저하되고 제조비용이 올라가는 문제점이 있었다.However, since the nonwoven fabric used is a hydrophilic short fiber nonwoven fabric, the amount of use of the foamed paper is increased by three times compared to the existing paper wallpaper. There was an issue going up.
또 폴리에스테르 스판본드 부직포를 사용한 것은 종이와 합포시켰을 때 양자간의 풀의 흡수량차이 및 합포건조시의 열수축자에 의해서 주름이 발생되는 단점이 있다.In addition, the use of a polyester spanbond nonwoven fabric has disadvantages in that wrinkles are caused by the difference in absorption of the grass when combined with paper and the heat shrinkage during drying of the fabric.
본 발명은 이러한 제반문제점을 해결한 것으로서 친수계 단섬유 부직포와 종이와의 합포공정대신에 가격이 싼 폴리에스테르 스판본드에 여러가지 약제를 패드-드라이-큐허법(pad-dry-cure)에 의해 처리함으로서 발포제의 거품형태유지성과 내수성 및 강도가 우수하고 시공시 풀흡수량이 적은 폴리에스테르 스판본드 발포벽지의 제조방법을 제공하는 데 그 목적이 있다.The present invention solves these problems, and the various chemical agents are treated by a pad-dry-cure in a cheap polyester spanbond instead of a lamination process of a hydrophilic short fiber nonwoven fabric and paper. It is an object of the present invention to provide a method for producing a polyester spanbond foamed wall paper having excellent foam form retention, water resistance and strength, and a small amount of water absorbed during construction.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
통상의 방법으로 용융방사된 폴리에스테르 연속필라멘트를 흡인연신시킨다음 이동하는 네트컨베이어상에 개섬적충시킨 필라멘트웨브를 200-230。C의 캘린더에서 가압하면서 폴리에스테르 스판본드를 제조한다.The polyester spunbond is prepared by suction stretching the melt-spun polyester continuous filament in a conventional manner, and then pressurizing the filament web that has been opened onto the moving net conveyor on a calendar of 200-230 ° C.
상기 폴리에스테르 스판 본드를 카복시메틸셀룰로즈 2∼4중량%, 폴리비닐알콜 5∼8중량%, 붕산 0.05∼0.2중량%, 트라칸트고부 3∼7중량% 및 물 89.95∼80.8중량%로 조성되어 있는 약제조성액내에 함침시킨다음에 웨트필업(wet pickup)이 90∼140중량%가 되도록 압착시키고 80∼130。C에서 30∼60초간 건조하고 열처리한다.The polyester span bond is composed of 2 to 4% by weight of carboxymethyl cellulose, 5 to 8% by weight of polyvinyl alcohol, 0.05 to 0.2% by weight of boric acid, 3 to 7% by weight of tracant, and 89.95 to 80.8% by weight of water. After impregnation in the pharmaceutical composition, the wet pickup is compressed to 90 to 140% by weight, dried at 80 to 130 ° C. for 30 to 60 seconds, and heat treated.
이어서 상기한 바와 같이 처리된 기포위에 통상의 방법으로 염화비닐발포액이나 아크릴발포액을 도포시킨 다음 30초정도 건조하여 발포시켜서 폴리에스테르 스판본드 발포벽지를 제조하는 것이다.Subsequently, a polyvinyl chloride foaming solution or an acrylic foaming solution is applied to the bubble treated as described above in a conventional manner, and then dried for about 30 seconds to foam to prepare a polyester spanbond foam wallpaper.
본 발명에서 발포거품의 안정성을 부여해주는 카복시메틸셀룰로즈가 4중량%를 초과하면 염화비닐발포액 또는 아크릴발포액의 계면장력이 저하되어 발포가 잘 되지 않으며, 2중량%미만이면 폴리에스테르의 소수성이 유지되어서 발포제의 발포를 방해하게 된다.In the present invention, when the carboxymethyl cellulose which gives the stability of the foam foam exceeds 4% by weight, the interfacial tension of the vinyl chloride foam or the acrylic foam liquid is lowered and the foaming is not good, and the hydrophobicity of the polyester is less than 2% by weight. It is retained to prevent foaming of the blowing agent.
또 본 발명에서 발포벽지의 수부에 의한 강도저하와 팽윤에 의한 내구성저하를 방지하기 위한 폴리비닐알콜이 8중량%를 초과하면 조성물의 점도상승으로 인하여 가공작업성과 제품의 유연성이 저하되고, 5중량%미만이면 내수성향상에 기여하지 못한다.In addition, when the polyvinyl alcohol exceeds 8% by weight in order to prevent the decrease in strength due to the hand part of the foamed wall and the durability decrease due to swelling in the present invention, the workability and flexibility of the product are reduced due to the increase in the viscosity of the composition. Less than% does not contribute to water resistance.
또 본 발명에서 폴리비닐알콜의 내수성을 향상시키기 위하여 겔화제로 첨가되는 붕산이 0.2중량%를 초과하면 겔화가 너무 급속하게 진행되어서 폴리비닐알콜이 스판본드에 불균일하게 부착되며, 0.05중량%미만이면 겔화에 영향을 주지 못해서 내수성향상에 기여할 수 없다.In addition, in the present invention, when boric acid added as a gelling agent exceeds 0.2% by weight in order to improve the water resistance of polyvinyl alcohol, the gelation proceeds so rapidly that polyvinyl alcohol adheres unevenly to the spanbond, and gelation is less than 0.05% by weight. It does not affect water resistance and therefore cannot contribute to the improvement of water resistance.
그리고 본 발명에서 스판본드의 공극에 의한 발포액의 계면장력저하 및 발포불균일성을 방지하기 위하여 사용되는 트라칸트고무(Traganth Gum)가 7중량%를 초과하면 폴리비닐알콜수용액을 산성화시켜 겔화온도를 떨어뜨리므로 약제가 공후 건조하기전에 약제가 상온에서 겔화되어 가공액의 수명을 단축시키고 약제처리후 스판본드상에 폴리비닐알콜수지가 불균일하게 부착되는 문제가 발생하며, 3중량%미만 첨가하면 스판본드공극을 메우는 효과가 저하되므로 발포성을 저하시키는 단점이 있다.In the present invention, when the tracant rubber used to prevent the interfacial tension decrease and the foaming nonuniformity of the foamed liquid due to the span bonds in the present invention exceeds 7% by weight, the polyvinyl alcohol aqueous solution is acidified to lower the gelation temperature. Therefore, the drug is gelled at room temperature before the drug is dried after drying, which shortens the life of the processing liquid and causes the problem that the polyvinyl alcohol resin is unevenly adhered to the span bond after the drug treatment. Since the effect of filling the voids is reduced, there is a disadvantage in reducing the foamability.
본 발명에서 조성물의 조성순서는 다음과 같다.Composition order of the composition in the present invention is as follows.
카복시메틸셀룰로즈, 트라칸드고무를 먼저 상온의 물에 교반, 분산시킨다음 여기에 폴리비닐알콜을 서서히 첨가하면서 분산시킨다음 액의 온도를 40~50。C까지 서서히 올리면서 폴리비닐알콜을 용해시킨다.Carboxymethylcellulose and tracand rubber are first stirred and dispersed in water at room temperature, and then polyvinyl alcohol is added and dispersed slowly. Then, polyvinyl alcohol is dissolved while gradually raising the temperature of the liquid to 40-50 ° C.
이어서 겔화제인 붕산을 교반하면서 서서히 투입한다.Subsequently, boric acid which is a gelling agent is slowly added while stirring.
상기와 같은 방법으로 제조된 발명의 폴리에스테르 스판본드 발포벽지는 스판본드자체의 내수성가 강도가 향상됨은 물론이거니와 발포액처리후 건조할때 거품이 양호하게 형성되며 벽지시공시에 풀사용량을 최소화 할 수 있다.Polyester spanbond foam wallpaper of the invention produced by the above method is not only improves the water resistance strength of the spanbond itself, but also foam is formed well when the foam solution is dried after treatment and can minimize the pool usage during wallpaper construction have.
