본 발명은 유리표면에 광경화 코팅되어 유리의 내스크래치성 및 굴곡강도를 향상시키는 페이스트 조성물에 관한 것으로서, 특히 디스플레이용 유리 표면에 코팅되어 보호막을 형성함으로써, 유리의 절삭 및 가공 시 발생되는 유리 결함을 방지하며, 가공 후에는 상기 보호막을 완전히 제거할 수 있는 것을 특징으로 한다. 이하, 본 발명을 상세하게 설명한다.The present invention relates to a paste composition that is photocurable coated on a glass surface to improve scratch resistance and flexural strength of glass. In particular, by coating a glass surface for display to form a protective film, glass defects occurring during glass cutting and processing It is characterized in that the protective film can be completely removed after processing. Hereinafter, the present invention will be described in detail.
본 발명은 스티렌-아크릴산 공중합체 및 페녹시 수지로 이루어진 바인더; 아크릴계 단량체; 다관능성 아크릴계 단량체; 광 개시제; 및 첨가제;를 포함하는 것을 특징으로 하는, 광경화성 강화유리 표면 보호 페이스트 조성물을 제공한다.The present invention provides a binder comprising a styrene-acrylic acid copolymer and a phenoxy resin; acrylic monomers; polyfunctional acrylic monomer; photoinitiator; and additives; provides a photo-curable tempered glass surface protection paste composition comprising a.
본 발명에 있어서, 상기 바인더는 점도 및 유리표면과의 부착력을 향상시켜, 유리표면에 보호막이 충분한 두께로 형성될 수 있도록 하며, 15 내지 35 중량%로 포함된다. 이는, 바인더가 15 중량% 미만으로 포함될 경우, 점도 및 부착성 감소로 유리표면으로 조성물이 흘러내려 충분한 두께로 보호막을 형성할 수 없고, 35 중량%를 초과할 경우에는 바인더 증가량에 비해 물성 향상 정도가 미미하고 과도한 점성으로 인해 오히려 보호막 형성 효율이 감소되기 때문이다. 따라서, 바인더는 15 내지 35 중량%, 바람직하게는 20 내지 30 중량%로 포함된다.In the present invention, the binder improves the viscosity and adhesion to the glass surface, so that a protective film can be formed on the glass surface to a sufficient thickness, and is included in an amount of 15 to 35% by weight. This is, when the binder is included in an amount of less than 15% by weight, the composition flows down to the glass surface due to a decrease in viscosity and adhesion, and thus a protective film cannot be formed to a sufficient thickness. This is because the protective film formation efficiency is rather reduced due to the insignificant and excessive viscosity. Accordingly, the binder is included in an amount of 15 to 35% by weight, preferably 20 to 30% by weight.
또한, 상기 바인더는 스티렌-아크릴산 공중합체 및 페녹시 수지를 포함하여 이루어진 물질로, 상기 스티렌 아크릴산 공중합체 100 중량부에 대해, 페녹시 수지를 5 내지 55 중량부, 바람직하게는 10 내지 45 중량부로 포함된다.In addition, the binder is a material including a styrene-acrylic acid copolymer and a phenoxy resin, and the amount of the phenoxy resin is 5 to 55 parts by weight, preferably 10 to 45 parts by weight, based on 100 parts by weight of the styrene-acrylic acid copolymer.

It cannot be prevented from being damaged by the environment and processing. In addition, when the content of the phenoxy resin exceeds 55 parts by weight, the hardness and flexural strength of the protective film are reduced, and peeling of the protective film becomes difficult.

In the present invention, the acrylic monomer is a peelable material for completely removing the photocurable protective film from the surface of the tempered glass after processing of the tempered glass is completed, and is included in an amount of 25 to 45 wt%. When the acrylic monomer is included in an amount of less than 25% by weight, the protective film cannot be completely removed from the glass surface, or the working time is prolonged, so that the process efficiency is lowered, and when it exceeds 45% by weight, the peelability is improved compared to the increased content The degree is not large, and the glass surface may be damaged by the improvement of peelability.
따라서, 아크릴계 단량체는 25 내지 45 중량%, 바람직하게는 30 내지 40 중량% 포함되며, 상기 아크릴계 단량체는 특별히 제한되지 않으나, 메틸아크릴레이트 단량체(methylacrylate monomer, MAM), 에틸아크릴레이트 단량체(ethyl acrylate monomer), n-부틸아크릴레이트 단량체(n-butyl acrylate monomer, BAM), 2-에틸헥실아크릴레이트(2-ethylhexyl acrylate), 아크릴산(acrylic acid) 및 메틸메타크릴레이트 단량체(methyl methacrylate monomer, MMA)로 이루어진 군 중에서 선택되는 어느 하나 이상일 수 있고, 바람직하게는 메틸아크릴레이트 단량체(methylarylate monomer, MAM)일 수 있다.Accordingly, the acrylic monomer is included in an amount of 25 to 45% by weight, preferably 30 to 40% by weight, and the acrylic monomer is not particularly limited, but a methylacrylate monomer (MAM), an ethyl acrylate monomer ), n-butyl acrylate monomer (BAM), 2-ethylhexyl acrylate, acrylic acid, and methyl methacrylate monomer (MMA) It may be any one or more selected from the group consisting of, and preferably may be a methyl acrylate monomer (MAM).

When the polyfunctional acrylic monomer is included in an amount of less than 25% by weight, the density of the protective film is reduced, so that sufficient scratch resistance to the glass surface cannot be exhibited. It is not large, and when the protective film is removed later, it is difficult to completely remove it.

점도, 두께, 연필경도, 부착력Viscosity, thickness, pencil hardness, adhesion
상기 제조된 시편에 대하여, 유리 기판에 인쇄 및 경화된 두께, 점도, 부착력 및 연필 경도를 측정하여 하기 표 2에 나타내었으며, 각각의 측정방법은 하기와 같다.With respect to the prepared specimen, the thickness, viscosity, adhesion, and pencil hardness printed and cured on a glass substrate were measured and shown in Table 2 below, and each measurement method is as follows.
<측정방법><Measuring method>
- 두께: 마이크로 미터(Mitsutoyo, MDC-25PJ)를 이용하여 코팅 후 총 두께(A, Glass + 경화 후 도막)와 코팅 전 Glass 두께(B)사이의 차이로 도막 두께를 측정하였다.- Thickness: Using a micrometer (Mitsutoyo, MDC-25PJ), the coating film thickness was measured as the difference between the total thickness after coating (A, glass + coating film after curing) and the glass thickness before coating (B).
A(Glass + 경화 후 도막) - B(코팅 전 Glass) = 도막 두께A (Glass + film after curing) - B (Glass before coating) = film thickness
- 점도: 시편 제조시 사용한, 페이스트 조성물을 점도계(Brookfield LV)를 이용하여 측정하였다.- Viscosity: The paste composition used in preparing the specimen was measured using a viscometer (Brookfield LV).
- 부착력: 경화물 표면을 부착력 시험기(Cross-cut, 1㎜/10teeth)를 이용하여 도막 표면을 격자 형태로 절단 후, 감압 점착 테이프를 부착하여 벗겨 내어 박리된 격자 조각을 확인하였다. -Adhesiveness: After cutting the surface of the cured product in a grid shape using an adhesion tester (Cross-cut, 1mm/10teeth), a pressure-sensitive adhesive tape was attached and peeled off to confirm the peeled grid piece.

또한, 바인더로서 스테렌-아크릴산 공중합체만을 포함한 비교예 2의 경우, 점도, 두께, 연필경도 및 부착력 모두에서 기준치에 미치지 못하는 결과를 나타내었으며, 바인더로서 페녹시만을 포함한 비교예 3의 경우에도 부착력을 제외한 점도, 두께, 연필경도 모두에서 기준치를 벗어났다.In addition, in the case of Comparative Example 2 including only the sterene-acrylic acid copolymer as a binder, the results did not meet the standard values in all of the viscosity, thickness, pencil hardness and adhesion, and even in the case of Comparative Example 3 including only phenoxy as the binder, the adhesion strength Viscosity, thickness, and pencil hardness were all out of the standard values except for .
굴곡강도 및 박리도Flexural strength and peelability
상기 제조된 시편 중, 실시예 2, 비교예 1 및 비교예 2에 대하여, 하기 방법으로 굴곡강도 및 박리도를 측정하여, 하기 표 3에 나타내었으며, 상기 시편의 굴곡강도 향상정도를 명확히 하기 위하여, 시편 제조 시 사용한 유리기판 즉, Bare Glass에 대해서도 굴곡강도 및 박리도를 측정하였다.Among the prepared specimens, Example 2, Comparative Example 1, and Comparative Example 2 were measured for flexural strength and peeling degree in the following manner, and are shown in Table 3 below, in order to clarify the degree of improvement in flexural strength of the specimen. , the flexural strength and peeling strength were also measured for the glass substrate used in the preparation of the specimen, that is, bare glass.
- 굴곡강도: 푸쉬풀게이지(Push Pull Gauge)를 150 mm/min으로 작동시켜 시편 및 Bare Glass의 굴곡강도를 측정하였다.- Flexural strength: The flexural strength of the specimen and bare glass was measured by operating a push pull gauge at 150 mm/min.
- 박리도: 강알카리 수용액에 시편을 담그어 코팅막이 벗겨지기 시작하는 시간을 측정하고, 코팅막이 벗겨지는 형태를 육안으로 관찰하였다.- Peelability: The time at which the coating film begins to peel off was measured by immersing the specimen in a strong alkaline aqueous solution, and the peeling shape of the coating film was observed with the naked eye.

상기 표 3을 통해 굴곡강도를 살펴보면, 바인더를 포함한 페이스트 조성물이 코팅된 실시예 2, 비교예 2 및 비교예 3 모두는 Bare Glass 보다 높은 굴곡 강도를 나타냄을 확인할 수 있고, 특히, 바인더가 스티렌-아크릴산 공중합체 및 페녹시 수지로 이루어진 실시예 2의 경우, 2,677 kgf/cm2의 가장 높은 굴곡강도를 가짐을 알 수 있다.Looking at the flexural strength through Table 3, it can be seen that all of Examples 2, Comparative Example 2 and Comparative Example 3 coated with the binder-containing paste composition exhibited higher flexural strength than Bare Glass. In particular, the binder was styrene- In the case of Example 2 made of an acrylic acid copolymer and a phenoxy resin, it can be seen that it has the highest flexural strength of 2,677 kgf/cm 2 .
박리도에 있어서는 바인더가 스티렌-아크릴산 공중합체 및 페녹시 수지로 이루어진 실시예 2와 바인더가 스티렌-아크릴산 공중합체만으로 이루어진 비교예 2가 빠른 시간 내에 조각(piece) 형태로 박리되는 반면, 바인더가 페녹시 수지만으로 이루어진 비교예 3은 박리에 오래 시간이 소요되고 필름(Film) 형태로 분해됨을 알 수 있다.In terms of the degree of peeling, Example 2 in which the binder was made of a styrene-acrylic acid copolymer and a phenoxy resin and Comparative Example 2 in which the binder consisted of only a styrene-acrylic acid copolymer were peeled off in a short time in the form of a piece, whereas the binder was a phenoxy resin. It can be seen that Comparative Example 3 made of only the sea resin takes a long time to peel and decomposes in the form of a film.
상기 결과로부터, 본 발명에 따른 페이스트 조성물을 유리기판에 광경화 코팅할 경우, 높은 굴곡강도를 가짐에 따라 유리 기판을 보호할 수 있음은 물론이고, 상기 코팅은 빠른 시간 내에 제거할 수 있음을 알 수 있다.From the above results, it can be seen that when the paste composition according to the present invention is photocurable coated on a glass substrate, the glass substrate can be protected as it has high flexural strength, and the coating can be removed in a short time. can
