투습도가 우수한 합성피혁Synthetic leather with excellent moisture permeability

본 발명은 투습도가 우수한 합성피혁에 관한 것이다.The present invention relates to a synthetic leather excellent in moisture permeability.

종래, 합성피혁에 통기성을 갖게하기 위하여 ① 엠보스로울등을 사용하여 기계적, 전기적으로 천공하는 방법, ② 기포(基布)위에 플래스티솔(plastisol)을 스텐실프린트하고, 노출한 기포의 직목(織目)을 이용하는 방법, ③ 물에 가용성인 DMF를 우레탄수지에 혼합하여 압연피복하고, 물로 씻어서 용출하여 통기성을 부여하는 방법등 다수의 방법이 제안되어 실시되고 있으나, 세공(細孔)을 형성하는 것만으로는 천연피혁의 감촉 및 느낌을 갖게하는 것이 곤란하다.Conventionally, in order to make breathable synthetic leather, ① Method of mechanically and electrically drilling by using embossing roll, ② Stencil printing of plastisol on air bubbles, Many methods have been proposed and practiced, such as a method of using a method, ③ a method of mixing DMF soluble in water with a urethane resin, rolling coating, washing with water, and eluting with water to provide breathability. It is difficult to have the texture and feel of natural leather only by doing.

그래서, 본 발명은 값이 싸고 내구성이 우수한 물성을 보유하는 염화비닐계 레더(leather)를 포함하여 합성피혁에 천연성분인 아교 또는 젤라틴을 배합해서 투습도를 부여하므로서, 천연피혁의 감촉 및 느낌을 갖는 신규한 합성피혁을 제공하는 것을 목적으로 한다.Thus, the present invention provides a texture and feel of natural leather by giving a synthetic leather glue or gelatin blended with natural leather, including vinyl chloride-based leather that has a low cost and excellent durability, giving moisture permeability It is an object to provide a novel synthetic leather.

본 발명자는 종래의 물에 가용성 물질인 DMF를 우레탄수지에 혼합해서 물과 치환해서 용출시키는 방법은 우레탄수지 이외에는 적용되지 않고, 범용성을 결여하기 때문에, 아교 또는 젤라틴이 갖는 흡습성을 유효하게 이용해서 천연피혁과 유사한 조직을 합성피혁 내부에 형성하는 것이 좋다는 점에 착안해서 연구를 행하였으나, 이러한 아교 또는 젤라틴은 열가소성 수지에 대하여는 균일분산성이 결여되고 배합이 어렵다는 문제점이 있었다.MEANS TO SOLVE THE PROBLEM The present inventors apply the conventional method of dissolving and dissolving DMF which is a soluble substance in water to a urethane resin, and eluting it with water. Although research was conducted focusing on the fact that a tissue similar to leather is formed inside a synthetic leather, such a glue or gelatin has a problem that the thermoplastic resin lacks uniform dispersion and is difficult to mix.

본 발명은 이러한 문제점을 해결하기 위해 이루어진 것으로, "합성피혁용수지 100중량부에 대하여 아교 또는 젤라틴을 희석분산해서 이루어진 첨가제를 아교 또는 젤라틴성분으로 하여 건조중량으로 0.5-10중량% 배합하고, 아교 또는 젤라틴을 균일하게 분산시킨 발포 또는 비발포 기층을 보유한다는 것"을 요지로 하는 투습도가 우수한 합성피혁에 관한 것이다. 합성피혁용수지로서는, 우레탄수지계, 염화비닐수지계의 수지가 대표적으로, 합성피혁용수지에 필요한 첨가제, 예를들어 가소제, 충전제, 활제, 발포제, 가교제 등을 혼합한 컴파운드를 사용해서 캘린더(calender) 가공으로 대표되는 피복법에 의하여 시이트를 형성하는 것이 바람직하다. 아교 또는 젤라틴성분의 배합비율은 0.5중량% 이하에서는 소정의 효과가 나오지 않고, 한편 10중량% 이상에서는 합성피혁의 내구성이 저하하므로, 0.5-10중량%의 범위가 바람직하다.The present invention has been made to solve the above problems, "0.5-10% by weight of a dry weight by using an additive made by diluting and dispersing glue or gelatin with respect to 100 parts by weight of synthetic leather resin, glue or gelatin component, glue Or to a foamed or non-foamed base layer in which gelatin is uniformly dispersed ”. As the synthetic leather resin, a urethane resin or a vinyl chloride resin is typically a calender using a compound in which additives required for the synthetic leather resin are mixed, for example, a plasticizer, a filler, a lubricant, a foaming agent, a crosslinking agent, and the like. It is preferable to form a sheet by the coating method represented by a process. Since the compounding ratio of the glue or gelatin component does not produce a predetermined effect at 0.5 wt% or less, while the durability of the synthetic leather is lowered at 10 wt% or more, the range of 0.5-10 wt% is preferable.

본 발명에 있어서는, 아교 또는 젤라틴성분은 파우더등을 첨가제로서 사용되는 가소제 또는 다른 조제(助劑)(분산안정제)로서 미리 희석분산해서 사용하는 것이 바람직하고, 염화비닐수지의 경우는 가소제로서 희석분산된 아교 또는 젤라틴을 사용하고, 우레탄수지의 경우에는 폴리올성분 또는 글리콜성분으로서 희석된 아교 또는 젤라틴을 사용해서 수지중에 균일분산시킨다.In the present invention, the glue or gelatin component is preferably used by diluting and dispersing the powder or the like in advance as a plasticizer or other preparation (dispersion stabilizer) used as an additive, and in the case of vinyl chloride resin, dilution and dispersion as a plasticizer. The prepared glue or gelatin is used, and in the case of urethane resin, it is uniformly dispersed in the resin using a diluted glue or gelatin as a polyol component or a glycol component.

기체층이 발포층인 경우에는, 톱(top) 층으로서 합성피혁용수지 100중량부에 대하여 아교 또는 젤라틴을 희석분산하여서 이루어지는 첨가제를 아교 또는 젤라틴성분으로하여 건조중량으로 0.5-10중량% 배합하고, 아교 또는 젤라틴을 균일하게 분산시켜서 이루어지는 톱층을 적층하는 것이 바람직하다. 표층에 우레탄, 아크릴, 부타디엔(butadiene)수지와 왁스, 카세인, 안료 등을 혼합한 피혁표면처리제가 도포되는 경우는, 카세인의 일부 또는 전부를 아교 또는 젤라틴으로 치환하여, 아교 또는 젤라틴을 0.5-10중량%를 함유하는 표면처리제를 도포하도록 하면, 하층과의 친화력이 우수하게 된다.In the case where the gas layer is a foam layer, 0.5-10% by weight of the additive is obtained by diluting and dispersing the glue or gelatin with 100 parts by weight of the synthetic leather resin as a top layer. It is preferable to laminate the top layer formed by uniformly dispersing glue or gelatin. When a leather surface treatment agent containing a mixture of urethane, acrylic, butadiene resin, wax, casein and pigment is applied to the surface layer, part or all of the casein is replaced with glue or gelatin, and the glue or gelatin is 0.5-10. When the surface treating agent containing the weight% is applied, the affinity with the lower layer is excellent.

본 발명에 의하면, 수지성분에 대하여 아교 또는 젤라틴을 균일분산시키는 것에 의해 아교 또는 젤라틴의 흡습성을 이용해서 제조되는 합성피혁시이트에 투습도를 필요로 하지 않을 수 있지만, 아교 또는 젤라틴 0.5-10중량%를 균일분산시켜서 이루어지는 합성피혁에 열수처리를 시행하면, 함유된 아교 또는 젤라틴성분의 일부가 제거되며, 표면에 털구멍모양의 세공이 다수형성되어서 투습도가 비약적으로 향상하여 천연피혁에 필적하는 투습도를 얻을 수 있음을 발견하였다.According to the present invention, although the moisture permeability may not be required in the synthetic leather sheet produced by using the hygroscopicity of the glue or gelatin by uniformly dispersing the glue or gelatin with respect to the resin component, 0.5-10% by weight of the glue or gelatin When hydrothermal treatment is performed on synthetic leather made by homogeneous dispersion, some of the glue or gelatin component is removed, and many pores in the form of pores are formed on the surface, which greatly improves the moisture permeability and obtains a moisture permeability comparable to that of natural leather. It was found that it can.

이하, 본 발명을 실시예에 따라서 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail according to embodiments.

[합성피혁 제조예 3]Synthetic Leather Production Example 3

상기한 제조예 1 및 2로 제조된 합성피혁시이트를 열수에 침지(浸漬)하여 열수처리를 시행하고 이것을 건조해서 합성피혁을 제조한다.Synthetic leather sheets prepared in Preparation Examples 1 and 2 were immersed in hot water, subjected to hydrothermal treatment, and dried to prepare synthetic leather.

일본공업규격 "가죽의 투습도 시험방법"(JISK 6549)에 의하여, 실시예 1-9에서 제조된 합성피혁시이트의 투습도를 시험해서, 미처리 천연피혁과 비교한 결과를 다음의 제1표에 표시한다.The moisture permeability of the synthetic leather sheet prepared in Example 1-9 was tested according to the Japanese Industrial Standard "Method of Testing Leather Moisture" (JISK 6549), and the results compared with untreated natural leather are shown in the following Table 1. .

그리고 본규격에서 투습도라함은, 일정시간에 단위면적의 막상물질을 통과하는 수증기의 양을 말하며, 온도 30±1℃에 있어서, 가죽을 경계면으로 하여, 한쪽의 공기를 상대습도 80±5%로, 반대쪽의 공기를 건조상태로 유지하였을때, 1시간에 이 경계면을 통과하는 수증기의 질량(㎎)을 그 가죽 1㎠마다 환산하여, 그 값을 투습도로 하고 있다.In this standard, the moisture permeability refers to the amount of water vapor that passes through the membrane of a unit area at a given time. At a temperature of 30 ± 1 ° C, one air is placed at a surface of leather with a relative humidity of 80 ± 5%. When the air on the other side is kept in a dry state, the mass (mg) of water vapor passing through this interface is converted into every 1 cm 2 of the leather in 1 hour, and the value is taken as the moisture permeability.

이상의 설명에서 명백한 바와 같이, 본 발명에 의하면, 합성피혁을 제조함에 있어, 아교 또는 젤라틴을 희석분산시켜서 이루어진 첨가제를 배합하는 것에 의하여 합성피혁 내부조직에 아교 또는 젤라틴성분을 균일하게 분산시켜 천연피혁과 유사한 조직을 형성하므로, 투습도가 우수함과 아울러, 천연피혁의 감촉과 느낌을 필요치 않게 할 수가 있다.As is apparent from the above description, according to the present invention, in the manufacture of synthetic leather, by combining an additive made by diluting and dissolving glue or gelatin, the glue or gelatin component is uniformly dispersed in the internal structure of the synthetic leather, By forming similar tissues, the moisture permeability is excellent, and the texture and feel of natural leather can be eliminated.

특히, 염화비닐레더는 값이 싸고, 내구성이 풍부하여 널리 이용되고 있으나, 천연피혁의 감촉 및 느낌에 뒤떨어져 싸구려 물건으로 되어 있었지만 본 발명에 의하여 천연피혁의 감촉 및 느낌을 부여한 결과, 대단히 실용성이 높은 것으로 된다. 또, 일반적으로 합성피혁으로서는 발포기체층의 위에 톱층을 적층하든지, 표면처리제를 도포해서 표층을 형성하지만, 이들 톱층 및 표층으로서 하층과 같은 모양의 조직을 보유하는 아교 또는 젤라틴을 균일분산시킨 층을 형성하도록 하면, 하층과의 친화력이 좋으므로 바람직하다.In particular, vinyl chloride leather is widely used because it is inexpensive and has abundant durability. However, the vinyl chloride leather has been inexpensive because it is inferior to the texture and feel of natural leather. It becomes. In general, as a synthetic leather, a top layer is laminated on a foamed gas layer, or a surface treatment agent is applied to form a surface layer. However, the top layer and the surface layer are uniformly dispersed with a glue or gelatin having a structure having the same shape as a lower layer. If it forms, since affinity with a lower layer is good, it is preferable.

그리고 아교 또는 젤라틴을 함유하는 수지조직은 그대로도 아교 또는 젤라틴의 흡습성에 의하여 유효한 투습도를 나타내지만, 이것에 열수처리를 시행하면, 아교 또는 젤라틴의 일부가 유실하여 천연피혁의 털구멍모양의 세공을 다수 형성하므로, 비약적으로 투습도를 향상시킬 수가 있다.Resin tissues containing glue or gelatin still exhibit effective moisture permeability due to hygroscopicity of glue or gelatin, but when the hydrothermal treatment is applied to this, part of the glue or gelatin is lost and pores in the shape of pores of natural leather are lost. Since a large number is formed, water vapor permeability can be improved remarkably.

따라서, 용도에 따라서 소망하는 투습도를 합성피혁에 갖게 할 수가 있다. 또, 본 발명에 관한 시이트는 본 출원인이 별도로 출원한 합성피혁, 즉, ① 합성피혁용수지에 대하여, 충전용 필터로서 50-150메시패스(mesh pass)의 혁분을 10-30중량% 배합하여서 이루어지는 비발포 합성피혁시이트, ② 합성피혁용수지에 대하여, 충전용 필터로서 50-150메시패스의 혁분을 5-15중량% 배합하여서 이루어지는 발포합성피혁시이트, ③ 합성피혁용수지에 대하여, 충전용 필터로서 50-150메시패스의 혁분을 10-30중량%와 아교 또는 젤라틴을 건조중량으로 0.5-10중량% 배합하여서 이루어지는 비발포합성피혁시이트, ④ 합성피혁용수지에 대하여, 충전용 필터로서 50-150메시패스의 혁분을 5-15중량%와 아교 또는 젤라틴을 건조중량으로 0.5-10중량% 배합하여서 이루어지는 발포합성피혁시이트와 적당하게 조합해서 적층하여 사용할 수 있음은 말할 것도 없다.Therefore, it is possible to give the synthetic leather a desired moisture permeability depending on the application. In addition, the sheet according to the present invention is blended with 10-30% by weight of a 50-150 mesh pass as a filler for the synthetic leather, that is, the synthetic leather resin filed separately by the present applicant.
