Example Embodiment

[0039] Preparation example 1

[0040] Preparation of radiation curable resin formulation A: Take a 250 ml glass bottle and add 15 g of ethyl acetate solvent into the glass bottle. Under high-speed stirring, add the following acrylic monomers in sequence: 10 grams of dipentaerythritol hexaacrylate, 2 grams of trimethylolpropane triacrylate and 14 grams of pentaerythritol triacrylate; the following oligomers: 34.5 grams of fat Family carbamate hexaacrylate [Etercure 6145-100, Eternal Company]; and the following photoinitiator: 4.5 grams of 1-hydroxycyclohexyl phenyl ketone, finally foamed into a solid content of about 80% and a total weight of about 100 grams of radiation curable resin formulation A.

Example Embodiment

[0041] Example 1 [The amount of radiation curable resin (24.86×80%) relative to the amount of thermoplastic resin (30.14×30%) is 220% by weight]

[0042] Preparation of anti-scratch layer:

[0043] Take a 250 ml glass bottle and add 25 g of ethyl acetate solvent into the glass bottle. Add the radiation curable resin in sequence under high-speed stirring: 24.86 grams of the radiation curable resin formulation A of Preparation Example 1 (solid content is about 80%, Eternal); thermoplastic resin: 30.14 grams of polymethacrylic acid polyol resin [Eterac 7365 -s-30, Eternal Corporation] (solid content approximately 30%) (glass transition temperature Tg is 95°C); and 4.2 grams of antistatic agent [GMB-36M-AS, Marubishi Oil Chem. Co ., Ltd)] (solid content is about 20%), and finally foamed into a coating composition with a solid content of about 30% and a total weight of about 85 grams. Coat the coating composition on the surface of the PET substrate with a film thickness of about 188μm ...

Example Embodiment

[0044] Example 2 [The amount of radiation curable resin (29.12×80%) relative to the amount of thermoplastic resin (25.88×30%) is 300% by weight]

[0045] Preparation of anti-scratch layer:

[0046] Take a 250 ml glass bottle and add 25 g of ethyl acetate solvent into the glass bottle. Add the radiation curable resin in sequence under high-speed stirring: 29.12 grams of the radiation curable resin formulation A of Preparation Example 1 (solid content is about 80%, Eternal); thermoplastic resin: 25.88 grams of polymethacrylic acid polyol resin [Eterac 7365 -s-30, Eternal Corporation] (solid content approximately 30%) (glass transition temperature Tg is 95°C); and 4.2 grams of antistatic agent [GMB-36M-AS, Marubishi Oil Chem. Co ., Ltd)] (solid content is about 20%), and finally foamed into a coating composition with a solid content of about 30% and a total weight of about 85 grams. Coat the coating composition on the surface of the PET substrate with a film thickness of about 188μm ...

Abstract

The invention discloses a paint component, which comprises thermoplastic resin which is chosen from poly-cycloolefine resin, polyester resin, polyacrylic ester resin or polyacrylic ester mixture, radiating cured resin which comprises acrylic acid series monomer which has one or several functional groups as polymerization unit, oligomer which has ethylene unsaturated functional group, and initiating agent, wherein the weight of radiating cured resin is 220-1000 weight percentage relative to the weight of thermoplastic resin. The paint component can increase the hardness of the paint component, prevents base plate from scoring and damaging in operation, and has the properties of high transparent, and no warping.

Description

technical field [0001] The invention relates to a coating, in particular to a coating composition coated on a base material, especially an optical plastic base material, which can enhance hardness and avoid scratches on the surface of the base material. Background technique [0002] General substrates are often scratched or worn due to careless handling, thus damaging the appearance or affecting their performance, especially optical substrates are often damaged due to vibration during transportation. The current solution is usually to paste a protective film on the surface of the substrate to prevent scratches, but this method leads to an increase in the cost of the substrate. In order to avoid the above disadvantages, a layer of paint is applied on the surface of the substrate to enhance the hardness and avoid scratches on the surface of the substrate. UV curing resin (UV curing resin) is used as an anti-scratch coating because of its short reaction time and high degree of...
