이하, 본 발명의 방염벽지 및 그 제조방법에 대해 상세히 설명하면 다음과 같다.Hereinafter, the flame retardant wallpaper and the manufacturing method of the present invention will be described in detail as follows.
본 발명의 방염벽지의 제조방법은 벽지원지의 일면을 물에 술팜산 및 구아니딘이 혼합된 수용성 방염제로 코팅하는 제1 코팅단계와, 상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지의 타면을 상기 수용성 방염제로 코팅하는 제2 코팅단계;를 포함하여 이루어진다.The method for manufacturing a flame retardant wallpaper of the present invention comprises a first coating step of coating one side of the wallpaper base paper with a water-soluble flame retardant in which sulfamic acid and guanidine are mixed in water, and the other side of the wallpaper base paper on which one side is flame retardant coated by the first coating step. A second coating step of coating the water-soluble flame retardant;
상기 제1 코팅단계는 상기 벽지원지의 일면에 수용성 방염제를 코팅하는 단계이다. The first coating step is a step of coating a water-soluble flame retardant on one surface of the wallpaper base paper.
상기 벽지원지는 닥펄프, 아바카펄프 및 목재펄프 중 선택된 1종 또는 2종 이상이 혼합된 지료를 이용하여 초지하여 제조된 것을 사용할 수 있는 등 크게 한정되는 것은 아니다.The wallpaper base paper is not particularly limited, for example, that one prepared by papermaking using one or a mixture of two or more selected from among duck pulp, abaca pulp, and wood pulp may be used.
한편, 상기 벽지원지는 피톤치드의 발산에 의해 스트레스 완화, 탈취, 살균효과 및 면역력을 증가시키기 위해, 편백추출물이 함유된 벽지를 사용하는 것이 좋다. 특히, 닥펄프 100중량부에 편백추출액 4~8중량부, 음이온성 분산제 2 내지 3중량부 및 전분 4 내지 5중량부를 혼합한 지료를 이용하여 초지 및 건조시켜 제조된 벽지원지를 사용하는 것이 좋다. 상기 편백추출액을 4중량부 미만으로 혼합할 경우 편백추출액의 제효과를 얻을 수 없고, 8중량부 초과로 혼합할 경우 제타전위가 음의 영역으로 변경되어 인장강도 등이 좋지 못한 문제가 있다. On the other hand, it is preferable to use wallpaper containing cypress extract in order to relieve stress, deodorize, sterilize, and increase immunity by the release of phytoncide for the wallpaper base paper. In particular, it is recommended to use a wallpaper base paper prepared by papermaking and drying using a stock containing 4 to 8 parts by weight of cypress extract, 2 to 3 parts by weight of anionic dispersant, and 4 to 5 parts by weight of starch to 100 parts by weight of daffodil pulp. . When the amount of the cypress extract is mixed in less than 4 parts by weight, the effect of the cypress extract cannot be obtained, and when it is mixed in more than 8 parts by weight, the zeta potential is changed to a negative region, so there is a problem of poor tensile strength and the like.
그리고 상기 벽지원지는 함수율이 1 내지 5%인 것을 사용하는 것이 좋다.And it is preferable to use the wallpaper base paper having a moisture content of 1 to 5%.
상기 벽지원지의 함수율이 1% 미만으로 이루어질 경우 정전기에 의해 먼지가 달라붙거나 먼지가 발생되어 방염벽지의 품질이 좋지 못하고, 5% 초과일 경우 수용성 방염제가 상기 벽지원지의 내부까지 효과적으로 침투되지 못하는 문제가 있다.When the moisture content of the wallpaper base paper is less than 1%, the quality of the flame retardant wallpaper is not good because dust adheres or dust is generated by static electricity. When the moisture content of the wallpaper base paper is more than 5%, the water-soluble flame retardant cannot effectively penetrate into the interior of the wallpaper base paper. there is a problem.
상기 제1 코팅단계는 상기 벽지원지를 상기 수용성 방염제가 수용된 저장조에 하부가 침지된 하부롤러와, 상기 하부롤러 상에 설치되는 상부롤러 사이를 통과시켜 상기 벽지원지의 일면을 코팅한다.In the first coating step, the wallpaper base paper is passed between a lower roller immersed in a storage tank containing the water-soluble flame retardant and an upper roller installed on the lower roller to coat one surface of the wallpaper base paper.
상기 수용성 방염제는 상기 벽지원지에 백화현상없이 난연성을 효과적으로 부여하고 화재시 포름알데하이드가 기준 이하로 방출되도록 하기 위해, 물 100중량부에 술팜산 40~45중량부, 구아니딘 40~45중량부가 혼합되어 이루어지는 것이 좋다. 상기 술팜산을 40중량부 미만으로 혼합할 경우 원지의 공극 내의 부착성이 좋지 못하고 난연성이 좋지 못하며, 45중량부 초과로 혼합될 경우 난연성은 우수하나 증진효과가 미비하다.The water-soluble flame retardant is mixed with 40 to 45 parts by weight of sulfamic acid and 40 to 45 parts by weight of guanidine in 100 parts by weight of water in order to effectively impart flame retardancy to the wallpaper base paper and release formaldehyde below the standard in case of fire. good to be done When the sulfamic acid is mixed in less than 40 parts by weight, the adhesion in the pores of the base paper is not good and the flame retardancy is not good, and when it is mixed in more than 45 parts by weight, the flame retardancy is excellent, but the enhancement effect is insufficient.
그리고 상기 구아니딘을 40중량부 미만으로 혼합할 경우 벽지원지의 미세한 공극 내의 부착성이 좋지 못하고, 난연성이 좋지 못하며, 45중량부 초과로 혼합할 경우 난연성은 우수하나 사용량 대비 난연성 증진효과가 미비하다.And when the guanidine is mixed in less than 40 parts by weight, the adhesion in the fine pores of the wallpaper base paper is not good, the flame retardancy is not good, and when it is mixed in more than 45 parts by weight, the flame retardancy is excellent, but the flame retardance enhancing effect is insufficient compared to the amount used.
다음으로, 상기 제2 코팅단계는 상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지의 타면을 상기 수용성 방염제로 코팅하는 단계이다.Next, the second coating step is a step of coating the other side of the wallpaper base paper on which one side is flame-retardant coated by the first coating step with the water-soluble flame-retardant agent.
이때 상기 벽지원지의 타면에 상기 수용성 방염제를 효과적으로 코팅하기 위하여, 상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지를 건조시킨 후 상기 벽지원지의 타면을 상기 수용성 방염제로 코팅하는 것이 좋다. 특히, 상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지를 함수율이 3~5%로 건조시키는 것이 좋다.In this case, in order to effectively coat the other side of the wallpaper base paper with the water-soluble flame retardant, it is preferable to dry the wallpaper base paper on which one side is flame retardant in the first coating step, and then coat the other side of the wallpaper base paper with the water-soluble flame retardant. In particular, it is preferable to dry the wallpaper base paper on which one side is flame-retardant coated by the first coating step to a moisture content of 3 to 5%.
상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지를 3% 미만의 함수율로 건조시킬 경우 많은 건조시간과 건조비용이 소요되고, 5% 초과의 함수율로 건조시킬 경우 수용성 방염제가 상기 벽지원지의 내부까지 효과적으로 침투되지 못하는 문제가 있다. When the wallpaper base paper on which one side is flame-repellent coated by the first coating step is dried to a moisture content of less than 3%, a lot of drying time and drying costs are required, and when drying to a moisture content of more than 5%, a water-soluble flame retardant is applied to the wallpaper base paper. There is a problem that it cannot penetrate effectively to the inside.
상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지의 건조는 한쌍의 히팅롤러에 의해 건조시키는 것이 좋다.It is preferable to dry the wallpaper base paper on which one side is flame-retardant coated by the first coating step by using a pair of heating rollers.
상기 제2 코팅단계는 상기 제1 코팅단계에 의해 일면이 방염코팅된 벽지원지를 방향전환롤러에 의해 상하방향을 전환시킨 후 상기 수용성 방염제가 수용된 저장조에 하부가 침지된 하부롤러와, 상기 하부롤러 상에 설치되는 상부롤러 사이를 통과시켜 상기 벽지원지의 타면을 코팅한다.The second coating step includes a lower roller immersed in a storage tank containing the water-soluble flame retardant after converting the wallpaper base paper on one side of which is flame-retardant coated by the first coating step in a vertical direction by a direction conversion roller, and the lower roller It passes between the upper rollers installed on the top and coats the other side of the wallpaper base paper.
상기 수용성 방염제는 상기 제1 코팅단계에서 사용한 수용성 방염제와 동일한 방염제를 사용한다.The water-soluble flame retardant uses the same flame retardant as the water-soluble flame retardant used in the first coating step.
마지막으로 상기 제2 코팅단계에 의해 타면이 코팅된 상기 벽지원지를 건조시킴으로서, 본 발명의 방염벽지를 얻을 수 있다. 이와 같이 제조된 방염벽지는 백화현상 등이 없고, 인장강도, 파열강도 등의 물성이 우수할 뿐만 아니라 내황화성 및 난연성이 우수한 이점이 있다.Finally, by drying the wallpaper base paper coated on the other side by the second coating step, the flame retardant wallpaper of the present invention can be obtained. The flame retardant wallpaper prepared in this way has no whitening phenomenon, and has excellent physical properties such as tensile strength and bursting strength, as well as excellent sulfurization resistance and flame retardancy.
이하, 본 발명의 방염벽지를 실시예를 들어 설명하면 다음과 같고, 본 발명의 권리범위는 하기의 실시예에 한정되는 것은 아니다.Hereinafter, the flame retardant wallpaper of the present invention will be described by way of example, and the scope of the present invention is not limited to the following examples.
