It can be easily coated on various materials requiring properties, and it has excellent surface decontamination ability to easily remove contaminants by simply removing dust, such as ball pen or magic, and microorganisms under certain conditions such as soil reclamation. The present invention relates to a biodegradable surface coating agent having a non-flammable and non-flammable, environmentally friendly surface contamination and non-flammable biodegradation is not harmful to the human body by itself and a method of manufacturing the same.
일반적으로 생분해성이 요구되는 각종 자재의 경우 생분성 외의 도막물성이 매우 취약하여 이를 표면코팅제로 커버하려는 시도가 되고 있으나, 이를 위한 표면 코팅제 역시 생분성 외의 도막물성이 매우 취약하여 표면코팅제로서의 기본물성이 부족하여 상용화가 어려운 실정이다.In general, in the case of various materials requiring biodegradability, there is an attempt to cover the coating film with a surface coating agent because of the very weak coating properties other than biopowder. This lack of commercialization is difficult.
또한 가구, 가방, 신발 등에 사용되는 천연피혁, 인조피혁이나 합성피혁, 인테리어필름, 생분해성부직포 등의 기재인 경우에 그 제품의 특성상 요구되는 물성 즉, 광택조절, 표면마모, 오염제거기능, 유연성 및 상온 굴곡성 및 난연성이 요구되나 종래기술로는 상기의 요구물성을 동시에 가지는 생분해성 표면 코팅제는 개발되어있지 않은 실정이다.In the case of substrates such as natural leather, artificial leather, synthetic leather, interior film, biodegradable nonwoven fabric, etc. used for furniture, bags, shoes, etc. And room temperature flexibility and flame retardancy are required, but in the prior art, a biodegradable surface coating agent having the above required properties has not been developed.

In this regard, Korean Patent Application No. 10-2010-0023456, which is filed under the name of the present applicant, discloses a surface contamination coating agent and a manufacturing method thereof, but does not disclose a technique for biodegradability. 860822 discloses an adhesive for removing contaminants with sterilizing and disinfecting properties, but it is composed of a non-permeable support layer and an adhesion layer, and adheres to a substrate, and then detaches after a certain period of time. The purpose and configuration are different.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 유연성, 난연성 및 굴곡성을 필요로 하는 가구, 가방, 슈즈, 인테리어 등에 사용되는 천연피혁, 합성피혁, 인조피혁, 인테리어필름, 생분해성부직포 등의 기재에 손쉬운 표면코팅으로 생분해성을 발현함과 동시에 광택조절, 난연성, 오염제거 기능을 가진 코팅제 및 그 제조방법을 제공함에 그 목적이 있다.The present invention is to solve the problems of the prior art as described above, natural leather, synthetic leather, artificial leather, interior film, biodegradable non-woven fabric used in furniture, bags, shoes, interior, etc. requiring flexibility, flame retardancy and flexibility It is an object of the present invention to provide a coating agent having a gloss control, flame retardancy, and decontamination function and a method of manufacturing the same while expressing biodegradability by easy surface coating on a substrate.
상기와 같은 과제를 해결하기 위하여 본 발명은, 실리콘계의 1종 이상의 고분자 수지조성물과 용매가 혼합된 기초고분자 용액 100중량부에 대하여, 경화제, 반응성 첨가제, 반응 촉진제 및 보조 첨가제를 함유하는 생분해성을 가지는 오염제거용 코팅제를 제공한다.In order to solve the above problems, the present invention is biodegradable containing a curing agent, a reactive additive, a reaction accelerator, and an auxiliary additive with respect to 100 parts by weight of a basic polymer solution in which at least one polymer-based resin composition and a solvent are mixed.

본 발명에 의하면 본 발명의 코팅제를 다양한 방법으로 여러 기재에 코팅하고 생분해성, 스크래치, 광택조절, 표면마모, 오염제거기능, 굴곡시험, 난연시험 등을 행하여 본 바 가구, 가방, 슈즈, 인테리어 용도의 각종 기재에서 요구하는 물성을 나타내어 가구, 가방, 인테리어, 슈즈 등의 용도에 사용되는 소재인 인조피혁, 합성피혁, 천연피혁 등의 표면오염물질을 제거하는데 효과적으로 사용할 수 있게 된다.According to the present invention, the coating agent of the present invention is coated on various substrates in various ways and subjected to biodegradability, scratch, gloss control, surface abrasion, decontamination function, bending test, flame retardant test, etc. It exhibits the physical properties required by various substrates, and can be effectively used to remove surface contaminants such as artificial leather, synthetic leather, and natural leather, which are materials used for furniture, bags, interiors, shoes, and the like.
본 발명을 실시하기 위해서는 먼저, 폴리머 분자 중에 실리콘폴리올(silicon polyol), 실리콘 고분자, 실리콘 경화제 중에서 선택되는 1종이상의 고분자 수지 3~80wt%와; 실리콘용제, 톨루엔, 자일런 중에서 선택되는 1종이상의 용매를 20~97wt%의 비로 하는 기초 고분자 용액을 준비한다.In order to practice the present invention, first, 3 to 80 wt% of at least one polymer resin selected from silicon polyol, silicone polymer, and silicone curing agent in the polymer molecule; A basic polymer solution having a ratio of 20 to 97 wt% of at least one solvent selected from a silicone solvent, toluene and xylene is prepared.
상기 기초 고분자 용액 100부를 기준으로 하여 오염물질을 막아주고 경화제 역할을 하는 실리콘경화제 5~30부, 표면에너지조절을 위한 실리콘 반응성첨가제인 하이드록시 실리콘 변성 폴리 아크릴레이트 1~5부, 극대의 가교밀도를 주어 반응촉진을 조절해주는 반응촉진제로 백금계 촉매 1~10부를 혼합한다. 5 to 30 parts of silicone curing agent to prevent contaminants and act as a curing agent based on 100 parts of the basic polymer solution, 1 to 5 parts of hydroxy silicone-modified polyacrylate, a silicone reactive additive for surface energy control, and maximum crosslinking density Give 1-10 parts of a platinum-based catalyst as a reaction promoter to control the reaction promotion given.
또한 상기 혼합물에 보조 첨가제를 0.1~16부를 고분자용액 100부를 기준으로 하여 첨가할 수도 있는데, 바람직하게는 상기 기초 고분자용액 100부에 대해 자외선에 의한 표면 변색을 막아주기 위한 UV흡수제 0.1~5부, 산화방지제 0.1~5부, 그리고 표면 광택을 조절하는 실리카 0.1~2부와 아크릴비드 0.1~10부, 우레탄비드 1-7부, 분산제 0.1~5부, 소포제 0.1~5부, 침강방지제 0.1~0.5부 등을 첨가하여 제반물성을 보완할 수도 있다.In addition, 0.1 to 16 parts of the auxiliary additive may be added to the mixture based on 100 parts of the polymer solution. Preferably, 0.1 to 5 parts of a UV absorber for preventing surface discoloration by ultraviolet rays with respect to 100 parts of the basic polymer solution, 0.1 ~ 5 parts of antioxidant, 0.1 ~ 2 parts of silica controlling surface gloss, 0.1 ~ 10 parts of acryl beads, 1-7 parts of urethane beads, 0.1 ~ 5 parts of dispersant, 0.1 ~ 5 parts of antifoam, 0.1 ~ 0.5 of antisettling agent It is also possible to supplement various physical properties by adding vices and the like.
본 발명의 실시에서, 본 발명의 코팅제에 사용되는 주 고분자로 실리콘폴리올(silicon polyol), 실리콘 고분자, 실리콘 경화제 중에서 선택되는 1종이상의 고분자 수지를 사용하는 이유는 본 발명의 주 목적인 오염제거기능, 난연성, 생분해성, 유연성 등을 부여하기 위함인데 그 조성물 간의 중량비는 크게 제한을 받지 않으나 전체 기초 고분자 용액 중 3~80wt%를 사용하는 이유는 코팅공정(도포량)의 용이함을 위한 점도의 조절이 필요하기 때문이며, 다른 첨가제와의 적정한 비율을 유지하기 위함이다.In the practice of the present invention, the reason for using at least one polymer resin selected from silicon polyol, silicone polymer, and silicone curing agent as the main polymer used in the coating agent of the present invention is a decontamination function, To impart flame retardancy, biodegradability, flexibility, etc. The weight ratio between the compositions is not particularly limited, but the reason for using 3 to 80 wt% of the total basic polymer solution is to control the viscosity for easy coating process (coating amount). This is to maintain an appropriate ratio with other additives.
또한 용매는 코팅공정의 용이함을 위한 점도의 조절 및 상기의 폴리머의 안정된 용액을 얻기 위함이고 그 함량을 20~97wt%로 하는 이유는 코팅시의 설비조건 및 도포량과 관계되어 그 이상일 경우 너무 점도가 높아 코팅이 불가능하고 그 이하일 경우에는 고형분의 코팅량이 적어 본 발명의 목적을 달성하기 어렵기 때문이다.In addition, the solvent is to control the viscosity for the ease of the coating process and to obtain a stable solution of the polymer, and the reason for the content of 20 ~ 97wt% is too viscous if more than that in relation to the equipment conditions and coating amount during coating If the coating is not high and less than that, it is because the coating amount of the solid content is small and it is difficult to achieve the object of the present invention.
상기에서 경화제로 실리콘 경화제를 사용하는 이유는 가교밀도를 극대 화시켜 오염물질의 근본적인 침투를 막기 위함이고, 본 발명의 최종용도인 가구, 가방, 슈즈, 인테리어 용도의 각종 기재에서 기본적으로 요구되는 촉감적인 측면에서의 자연스러움을 얻기 위함이고, 또한 경화제가 실리콘으로써 본 발명의 목적을 달성하기위해서는 필수적이기 때문이다.The reason why the silicone curing agent is used as the curing agent is to maximize the crosslinking density to prevent fundamental penetration of contaminants, and the touch basically required in various substrates of furniture, bags, shoes, and interior applications, which is the end use of the present invention. This is because it is necessary to obtain naturalness from an aspect, and it is essential for the curing agent to achieve the object of the present invention as silicone.
고첨가량을 상기와 같이 하는 이유는 상기의 양보다 적을 경우 본 발명의 효과를 충분하게 얻기 힘들고, 그 이상일 경우에는 그 효과의 정도가 더 이상 증가 하지 않기 때문이다. The reason why the high addition amount is as described above is that when the amount is less than the above amount, the effect of the present invention is not sufficiently obtained, and when it is higher than that, the degree of the effect does not increase any more.
또한 경화촉매인 백금계 촉매는 실리콘폴리올(silicon polyol), 실리콘 고분자, 실리콘 경화제 등으로 구성되는 그룹에서 선택되는 1종 이상의 고분자간의 가교정도와 속도를 제어하기 위해 사용되는 것으로 첨가량을 상기와 같이 하는 이유는 코팅공정과 관계되어 용액의 안정성 유지 및 경화조건의 효율성 때문이다. In addition, the platinum catalyst, which is a curing catalyst, is used to control the degree and speed of crosslinking between one or more polymers selected from the group consisting of silicon polyol, silicone polymer, and silicone curing agent. This is due to the stability of the solution and the efficiency of the curing conditions in relation to the coating process.
또한, 상기에서 자외선에 의한 표면 변색 방지용으로 사용하는 UV흡수제를 0.1~5부로 하는 이유는 0.1부 이하에서는 그 효과가 미약하고 5부 이상에서 는 더 이상의 효과를 기대할 수 없고 비경제적이기 때문이고, 산화방지제와 표면광택조절제로 사용되는 실리카 역시 같은 이유로 상기 함량으로 사용할 수 있다. In addition, the reason why the UV absorber used for preventing surface discoloration by ultraviolet rays is 0.1 to 5 parts because the effect is less than 0.1 parts or less and more economical effects can not be expected from 5 parts or more, and it is uneconomical. Silicas used as inhibitors and surface gloss modifiers may also be used in this amount for the same reason.
상기 표면에너지조절용으로 사용하는 실리콘계 반응성 첨가제는 실리콘으로의 반응을 통하여 도막표면의 표면에너지를 극소화시키기 위함인데 그 함량을 1 ~5부로 하는 이유는 상기의 양보다 적을 경우 본 발명의 효과를 충분하게 얻기 힘들고, 그 이상일 경우에는 본 발명의 효과가 더 이상 상승하지 않고 불순물로 작용하며 도막의 강도를 저하시키기 때문이며, 또한 제조원가의 합리성을 얻기 위함이다.The silicon-based reactive additive used for the surface energy control is to minimize the surface energy of the surface of the coating film through reaction with silicon. The reason for the content of 1 to 5 parts is less than the above amount to sufficiently effect the effect of the present invention. It is because it is difficult to obtain, and if it is more than that, the effect of the present invention does not increase any more, it acts as an impurity and lowers the strength of the coating film.
상기에서 점도 및 고형분 조절용으로 실리콘용제, 톨루엔, 자일렌 중 1종 이상을 사용하는 이유는 실리콘 고분자의 특성상 비극성인 용제에만 용해되는 특징이 있고 용액안정성이 뛰어나기 때문이다.The reason for using at least one of the silicone solvent, toluene, and xylene for viscosity and solids control is because it is characterized by dissolving only in the non-polar solvent in the nature of the silicone polymer and excellent in solution stability.
또한 물성보완을 위해 사용하는 아크릴비드와 우레탄비드는 소광효과의 부여, 스크래치 방지, 표면촉감 개선용으로 첨가될 수 있고 함량을 상기와 같이 하는 이유는 상기의 첨가량 이하일 경우 그 효과를 기대하기 어렵고 그 이상일 경우에는 표면도막의 크랙 및 연신백화의 발생이 우려되기 때문이다. In addition, acryl beads and urethane beads used to supplement the properties can be added for the addition of matting effect, scratch prevention, surface feel improvement and the reason for the content as described above is difficult to expect the effect when the addition amount is less than the above This is because there is a concern that cracks and stretch whitening of the surface coating film are caused in the above cases.
또한 본 발명에서의 산화방지제, 소포제, 침강방지제 등은 통상의 것을 사용할 수 있다.In addition, an antioxidant, an antifoamer, a sedimentation inhibitor etc. in this invention can use a normal thing.
