Embodiment 1
[0023] An acrylic surface treatment process:
[0024] 1. Select a suitable acrylic 1 (acrylic plate in this embodiment);
[0025] 2. Spray a plastic primer on the back of the acrylic 1, and after the plastic primer is cured for 10 minutes, a plastic primer layer 2 is formed on the surface of the acrylic 1;
[0026] 3. Apply silicone structural adhesive 3 on the surface of the plastic primer layer 2, and bond it to the base layer 4 (such as figure 2 shown).
Embodiment 2
[0028] An acrylic surface treatment process:
[0029] 1. First, carve acrylic 1 into three-dimensional acrylic characters;
[0030] 2. Brush the plastic primer on the part of the back of the carved acrylic 1 that is to be bonded to the light bar 6. After the plastic primer is cured for 8 minutes, a plastic primer layer 2 is formed on the surface of the acrylic 1;
[0031] 3. Put the lighting board 6 in place, and apply silicone structural glue 3 between the lighting board 6 and the plastic primer layer 2 (such as figure 2 shown).
Embodiment 3
[0033] An acrylic surface treatment process:
[0034] 1. Select the appropriate acrylic 1;
[0035] 2. Spray a plastic primer on the surface of the acrylic 1, and after the plastic primer is cured for 12 minutes, a plastic primer layer 2 is formed on the surface of the acrylic 1;
[0036] 3. Print UV picture 5 on acrylic 1, such as image 3 shown.
[0037] After the product prepared in Examples 1-3 was left to stand at normal temperature for one month, the surface was scratched with a blade, and there was no paint drop substantially. Therefore, it can be seen from the test that:
[0038] 1. The surface roughness of acrylic is different, and the smooth and smooth effect can be obtained through the pretreatment of plastic primer; the silicone structural adhesive is used to enhance the adhesion;
[0039] 2. The low polarity of acrylic surface usually has poor adhesion with direct silicone structural adhesive, and better adhesion performance can be obtained through plastic pri...
