Example Embodiment
[0027] Example 1
[0028] An acrylic glue includes the following raw materials in parts by weight:
[0029] 20 parts of PMMA resin, 40 parts of ethyl acetate, 35 parts of methylene chloride, 0.01 part of curing agent, 0.35 part of light diffusing agent, and 0.1 part of chloroform.
[0030] Further, the PMMA resin has a melt index of 3.0~3.4g / 10min and a density of 1.17~1.21g / cm 3 The methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the transparency and impact resistance of the composite acrylic sheet.
[0031] Further, the curing agent is p-hydroxybenzene sulfonic acid, which promotes the curing of the acrylic glue and improves the curing efficiency.
[0032] Further, the light diffusing agent is an acrylic organic light diffusing agent, which can increase the scattering and transmission of light in the transparent plastic injection layer, shield the light source and the glare light source, and make the entire resin emit softer, more beautiful...
Example Embodiment
[0034] Example 2
[0035] 15 parts of PMMA resin, 60 parts of ethyl acetate, 20 parts of dichloromethane, 0.015 parts of curing agent, 0.65 parts of light diffusing agent, and 0.25 parts of chloroform.
[0036] Further, the PMMA resin has a melt index of 3.0~3.4g / 10min and a density of 1.17~1.21g / cm 3 The methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the transparency and impact resistance of the composite acrylic sheet.
[0037] Further, the curing agent is p-hydroxybenzene sulfonic acid, which promotes the curing of the acrylic glue and improves the curing efficiency.
[0038] Further, the light diffusing agent is an acrylic organic light diffusing agent, which can increase the scattering and transmission of light in the transparent plastic injection layer, shield the light source and the glare light source, and make the entire resin emit softer, more beautiful and elegant light , To achieve a comfortable effect of light transmission and...
Example Embodiment
[0040] Example 3
[0041] 20 parts of PMMA resin, 50 parts of ethyl acetate, 25 parts of dichloromethane, 0.012 parts of curing agent, 0.5 parts of light diffusing agent, and 0.15 parts of chloroform.
[0042] Further, the PMMA resin has a melt index of 3.0~3.4g / 10min and a density of 1.17~1.21g / cm 3 The methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the transparency and impact resistance of the composite acrylic sheet.
[0043] Further, the curing agent is p-hydroxybenzene sulfonic acid, which promotes the curing of the acrylic glue and improves the curing efficiency.
[0044] Further, the light diffusing agent is an acrylic organic light diffusing agent, which can increase the scattering and transmission of light in the transparent plastic injection layer, shield the light source and the glare light source, and make the entire resin emit softer, beautiful and elegant light , To achieve a comfortable effect of light transmission and opaci...
