（産業上の利用分野）
本発明はガラス又は鏡の保護膜材、特に鏡の実正塗料又
はガラスに塗布後、紫外線照射により硬化して、鏡、ガ
ラスの破損時の破片飛散を防止する紫外線硬化型保護膜
材に関するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention is a protective film material for glass or mirrors, in particular a mirror coating material or after being applied to the glass, it is cured by ultraviolet irradiation, and when the mirror or glass is damaged. This invention relates to an ultraviolet curing protective film material that prevents the scattering of debris.
（従来の技術）
近年、大型のガラスや鏡が装飾的に使用されるようにな
ってきたが、これらのガラス、鏡は衝撃又は歪による破
損時の破片の飛散防止はできず、衝撃、歪等で破損した
時にガラス片が飛散して、地震その他の災害時に不慮の
人身事故を起す欠点がある。(Prior art) In recent years, large glasses and mirrors have come to be used decoratively, but these glasses and mirrors cannot prevent fragments from scattering when they break due to impact or distortion. The drawback is that when broken, glass fragments can fly off, causing unexpected personal injury in the event of an earthquake or other disaster.
このような危険の防止の為、板ガラス、鏡に表面硬度が
高（伸び率の低い樹脂膜を粘着剤で貼付けたものが知ら

脂膜自体に亀裂を生じて、十分な飛散防止効果が得られ
なかった。熱により硬化する塗料で同じような効果を狙
ったものがあるが、塗料中の溶剤が鏡の実正塗料を侵し
たり、溶剤の使用による作業環境、安全衛生面上の問題
がある。In order to prevent such dangers, it is known that plate glass and mirrors have a resin film with high surface hardness (low elongation rate) attached with adhesive, but the adhesive strength between the plate glass and mirror and the resin film is weak. If the glass is broken, the glass pieces may come off from the resin film, or
Even if the adhesive strength was sufficient, the elongation rate of the resin film was low, so cracks were generated in the resin film itself, and a sufficient scattering prevention effect could not be obtained. There are paints that harden with heat that aim to achieve a similar effect, but the solvent in the paint can corrode the actual paint on the mirror, and the use of solvents poses problems in terms of work environment and health and safety.
さらに、鏡の銀層又はその上の実正塗料層は、水、湿気
に弱く、銀層とガラスの間で界面剥離して、曇化を起こ
す欠点がある。Furthermore, the silver layer of the mirror or the actual paint layer thereon is susceptible to water and moisture, and has the drawback of peeling at the interface between the silver layer and glass, causing clouding.
（問題点を解決するための手段） 本発明は、前述の欠点を解決することを目的とする。(Means for solving problems) The present invention aims to overcome the aforementioned drawbacks.
本発明は主剤Ａとしてウレタンアクリレートオリゴマー

量部を混合して成り、所要に応じて熱重合禁止剤０．０
１〜ＩＯ重量部及び／又はゴム用充填剤０〜２００重量
部をも混合して成るものである。The present invention is made by mixing 100 parts by weight of urethane acrylate oligomer as main ingredient A, and 10 to 200 parts by weight of a reactive diluent and 0.1 to 20 parts by weight of photopolymerization initiator as main ingredients B and C. Depending on the thermal polymerization inhibitor 0.0
1 to 10 parts by weight of IO and/or 0 to 200 parts by weight of a rubber filler are also mixed therein.

布が困難になり、２００重量部より多くては膜が硬くて
脆く、飛散防止効果を失ってしまう。The reactive diluent of main component B is a diluent having an acrylic group (0-C-CH=CH2) or methacrylic in its molecular structure, and it dilutes the oligomer to lower the viscosity and make it easier to coat. , which imparts flexibility to the cured product and improves its adhesion to the adherend, and is preferably used in an amount of 10 to 200 parts by weight per 100 parts by weight of the main ingredient A. If it is less than 10 parts by weight, there will be no diluting effect and the viscosity of the paint will be high, making it difficult to apply. If it is more than 200 parts by weight, the film will be hard and brittle and will lose its anti-scattering effect.
主剤Ｃの光重合開始剤は、紫外線を吸収して重合反応を

部より少なくては紫外線による硬化が遅くなり、２０重
量部より多くては硬化速度は上がらないのに独特の臭い
が残ったり、膜が黄変したりする。The photopolymerization initiator as the main component C is one that absorbs ultraviolet light to initiate a polymerization reaction, has absorption in the ultraviolet region of 300 to 450 nm, and includes carbonyl compounds, sulfur compounds, azo compounds, and the like. The amount used is preferably 0.1 to 20 parts by weight based on 100 parts by weight of the main agent A. If it is less than 0.1 parts by weight, curing by ultraviolet rays will be slow, and if it is more than 20 parts by weight, the curing speed will not increase, but a unique odor may remain or the film may turn yellow.
Ｄの熱重合禁止剤は主剤Ａｌ００重量部に対して０．０

。The thermal polymerization inhibitor D is 0.0 parts by weight based on 00 parts by weight of the main material Al.
1-10 parts by weight is preferred. If it is less than 0.01 part by weight, the effect of preventing gelation due to heat, which is the purpose of addition, cannot be obtained, and if it is more than 10 parts by weight, curing by ultraviolet rays is inhibited, the curing time becomes longer, and the surface becomes tacky. Some will remain.
ゴム用充填剤は塗布特性を整える為、添加したほうが良

０重量部が好ましい。２００重量部より多くては塗料の
粘度が上がり過ぎて塗布が難しくなったり、膜が硬くて
脆いものになり、飛散防止効果を失ったりする。It may be better to add filler for rubber to adjust the coating properties, and it is 0 to 20 parts by weight per 100 parts by weight of base material A.
0 parts by weight is preferred. If the amount is more than 200 parts by weight, the viscosity of the paint will increase too much, making it difficult to apply, and the film will become hard and brittle, losing its anti-scattering effect.

を生ずることがない。(Function) The protective film material of the present invention can be easily cured in a short time by irradiating it with ultraviolet rays after coating, and can be dried on a much shorter production line than the production line for conventional heat-drying protective film materials. Furthermore, since it is solvent-free, problems such as solvent recovery and work environment do not occur.
