Embodiment 1

[0028] A kind of acrylic glue, comprises the raw material of following weight portion:

[0029] 20 parts of PMMA resin, 40 parts of ethyl acetate, 35 parts of dichloromethane, 0.01 part of curing agent, 0.35 parts 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 Methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the light transmittance and impact resistance of composite acrylic panels.

[0031] Further, the curing agent is p-hydroxybenzenesulfonic 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 glue injection layer, cover the light source and the glare light source, and make the whole resin emit softer, more beautiful and eleg...

Embodiment 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 Methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the light transmittance and impact resistance of composite acrylic panels.

[0037] Further, the curing agent is p-hydroxybenzenesulfonic 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 glue injection layer, cover the light source and the glare light source, and make the whole resin emit softer, more beautiful and elegant light. , to achieve the comfortable effect of light transmission and opacity.

Embodiment 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 Methyl hydroxymethacrylate, which has excellent transparency and impact properties, enhances the light transmittance and impact resistance of composite acrylic panels.

[0043] Further, the curing agent is p-hydroxybenzenesulfonic 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 glue injection layer, cover the light source and the glare light source, and make the whole resin emit softer, more beautiful and elegant light. , to achieve the comfortable effect of light transmission and opacity.

Abstract

The invention provides acrylic glue. The acrylic glue comprises the following raw materials in parts by weight: 10 to 25 parts of PMMA resin, 40 to 60 parts of ethyl acetate, 20 to 35 parts of dichloromethane, 0.005 to 0.02 part of a curing agent, 0.3 to 0.7 part of a light diffusant and 0.1 to 0.25 part of trichloromethane. A composite acrylic plate manufactured by the acrylic glue comprises a bottom layer plate, a glue layer and an upper layer plate; and the glue layer is formed after the acrylic glue is solidified; a gap between the bottom layer plate and the upper layer plate is filled with the glue layer. The manufacturing process of the composite acrylic plate comprises the following steps: S1, selecting materials; S2, sticking a film on the surface; S3, injecting filling glue; S4, performing edge pressing; S5, supplementing glue; and S6, performing subsequent treatment. The acrylic glue provided by the invention has the advantages of high curing rate, excellent adhesion effect,less possibility of cracking and no bubble and crystallization defects during adhesion; and the composite acrylic plate manufactured by the acrylic glue through adhesion has stronger transmitting brightness and can reduce the energy consumption of a light source compared with a traditional composite acrylic plate.

Description

technical field [0001] The invention relates to the technical field of acrylic light box decoration, in particular to an acrylic glue and a manufacturing process using the acrylic glue for composite acrylic board. Background technique [0002] Acrylic board, also known as specially treated plexiglass, is a replacement product of plexiglass, which has the characteristics of good transparency, chemical stability, weather resistance, easy dyeing, easy processing and beautiful appearance; as people become more and more interested in advertising benefits It is worth noting that acrylic boards are widely used on advertising signs because of their good performance. Light boxes or signboards made of acrylic have good light transmission performance, pure color, rich colors, beautiful and smooth, taking into account both day and night effects, and long service life. , Does not affect the use and other characteristics. [0003] At present, glue bonding is more and more common in all w...
