The transparent acrylic plate 122 is 90 ~ 98wt% acrylic resin, 2 ~ 10wt% acrylic strength enhancer, 0.1 ~ 10wt% Poly (ethylene glycol) (PEG), 0.1 ~ 10wt Poly (vinylidene fluorolide) (PVDF) Use is made of a mixture of%.

The acrylic resin is a polymer from an ester such as acrylic acid or methacrylic acid, and is a polymer of methyl methacrylate ester (methyl methacrylate). It is colorless and transparent, and light, especially ultraviolet light, transmits better than ordinary glass (refractive index 1.49). It does not discolor when exposed to the outdoors, has good chemical resistance, and has excellent electrical insulation and water resistance. When the amount of the acrylic resin is less than 90wt%, transparency and processability may be lowered, and when the amount of the acrylic resin is more than 98wt%, durability may be reduced, so the amount of the acrylic resin is 90 to about 100% of the total transparent acrylic plate content. It is preferable to limit the amount to 98 wt%.

The acrylic strength modifier increases the strength of the transparent acrylic plate 122 to impart durability and scratch resistance, and uses a core-shell copolymer.

The core-shell copolymer forms a core latex, and the monomers used as the core latex and the shell are styrene, glycydyl methacrylate (GMA), and methyl methacrylate (MMA). It was polymerized.

That is, 75 to 86 wt% of DI water (deionized water) with an elevated temperature of 45 to 50 ° C., 13 to 25 wt% of n-butyl acrylate (BA) monomer and 0.05 to 0.5 wt% of EGDMA (ethylene glycol dimethacrylate) After the temperature was raised to 70 ℃, the reaction temperature, KPS (potassium persulfate) 0.05 ~ 0.5wt% and SBS (sodium bisulfate) 0.01 ~ 0.1wt% and reacted for 4-5 hours and then the temperature to 90 ℃ 25 to 35wt% of the core latex (a) polymerized by post-reacting the unreacted monomer by raising the amount;

DI water; deionized water (b) 50-60wt%; and

SDBS (sodium dodecyl benzene sulfate) (c) 0.01 ~ 0.2wt%; After stirring for 1 to 2 hours,

When the amount of the acrylic strength enhancer is less than 2wt%, it is difficult to expect an increase in strength, and when the amount of the acrylic strength enhancer exceeds 10wt%, transparency and processability may be degraded. It is preferable to limit to within the range of 2-10 wt%.

The polyethylene glycol (PEG) is used to improve processability. When the amount is less than 0.1 wt%, it is difficult to expect a synergistic effect of melt processability, and when it exceeds 10 wt%, it is transparent. Since it may affect the durability of the acrylic plate, the amount of the polyethylene glycol (Poly (ethylene glycol); PEG) is preferably limited to within the range of 0.1 to 10wt% based on the content of the total transparent acrylic plate.

The polyvinylidene fluorolide (Poly (vinylidene fluorolide): PVDF) is a chemical resistance, when the amount is less than 0.1wt% it is difficult to expect the improvement of chemical resistance, when it exceeds 10wt% transparent acrylic Since it may affect the durability of the plate, the amount of the polyethylene glycol (Poly (ethylene glycol); PEG) is preferably limited to the range of 0.1 to 10wt% with respect to the content of the total transparent acrylic plate.

Specific manufacturing example of the transparent acrylic plate 122,

A mixture composition of 93 wt% acrylic resin, 6 wt% acrylic strength enhancer, 0.5 wt% poly (ethylene glycol) (PEG), and 0.5 wt% poly (vinylidene fluorolide) (PVDF) is injected between the casting plate glass and the glass. It is made by hardening at 80 degreeC.
