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...

Abstract

The invention discloses an acrylic surface treatment process. The process is characterized in that an acrylic material in a proper specification and size is selected according to production requirements; the part to be bonded to another component is coated or sprayed with plastic primer; after the plastic primer is cured, adhesive glue can be directly printed or applied to the surface of the part, so that the part can be boned to another component. With the adoption of the acrylic surface treatment process, the problems of low tension and low polarity of the acrylic surface are solved, and the problems that a component directly bonded to an acrylic surface is likely to fall or unfixed and the like due to thermal expansion and cold shrinking caused by temperature difference are solved. The acrylic surface treatment process is advanced, reasonable, low in cost and simple in operation; product quality is more reliable and stable, the maintenance frequency and cost are reduced, the market competitiveness is improved, and remarkable economic benefits are produced.

Description

technical field [0001] The invention relates to an acrylic surface treatment process, which belongs to the technical field of acrylic and is applied to the advertising signboard industry. Background technique [0002] At present, acrylic materials are used more and more widely in all walks of life. Acrylic has excellent wear resistance, good stability, and corrosion resistance to various chemicals. It is a new type of environmentally friendly material that is loved by most people. With the It is widely used, and people have higher and higher requirements for its performance in all aspects. The bonding fastness is particularly important. The combination of ordinary acrylic and other materials can be combined and bonded by silicone structural adhesive, but the surface of acrylic Low polarity, less tension. Ordinary silicone structural adhesives cannot achieve the corresponding fastness in bonding, so that the quality of the product cannot be well guaranteed. Therefore, a met...
