Technical Field
The invention relates to an ultraviolet curing cleaning adhesive, a preparation method and application thereof.
Background
In daily life or industrial production, a cotton swab or a cloth-head wiping rod is often used to clean fine objects. However, in the field of electronic and photoelectric industries, most of precision electronic products or optical products are unqualified because foreign matters which do not meet the quality requirement are adsorbed on the surface of the products in the production and inspection processes. The cleaning by using a conventional ion air gun or a common cotton swab can not achieve good effect, and the quality can not be well guaranteed. If a large amount of water or solvent is used for washing, on one hand, a large amount of waste water and waste liquid are generated, and on the other hand, the subsequent processes such as drying are involved, so that the operation is complex.
In the field of precision manufacturing, cleaning and dust removal by using cleaning glue which can be made into various shapes become a more appropriate scheme. The red glue is widely used in the market at present, and the main components of the red glue are ethyl acetate solvent, glue main resin polyethylene-vinyl acetate and pigment. The cleaning glue is dipped by using a stick, and the solvent is volatilized for use. But the operation is not convenient enough because the solvent needs to be waited for volatilization; the solvent can cause environmental pollution and is not environment-friendly enough; after the solvent is volatilized, the colloid is hard, and dust and particles cannot be easily removed from a part of complex and fine structures. In addition, when the adhesion of the glue is not enough, the cleaning effect on impurities is not good, the adhesion is too good, and the glue is easy to adhere to the cleaned parts and is not easy to take down, so that different customers have different requirements on the adhesion of the glue in the practical application.
Patent CN102533171B discloses a solid cleaning glue and a preparation method thereof, and provides a solid cleaning glue which is synthesized by a soft monomer, a hard monomer, an initiator, a solvent and a functional auxiliary agent through a solution polymerization method, the synthesis process is complex, and a large amount of waste liquid can be generated. In the patent CN102676085B, the preparation of the yellow cleaning glue needs a base of 120-130 ℃, and then the yellow cleaning glue is obtained by stirring at 95-100 ℃, and the preparation is also complex.

The test results of each composition prepared in examples 1 to 6 and comparative examples 1 to 2 were as follows:
the use method comprises the following steps: one end of a cotton swab is dipped into uncured cleaning glue for dipping, and the cotton swab is wrapped on a rod head to form an oval glue head with the thickness of about 1mm and the diameter of about 3-5 mm. After sufficient curing (for comparative example 1, curing is the drying time due to the non-UV curing system) was used. When in use, the glue head is aligned to the position of the impurity and lightly stuck at an angle of 60-90 degrees.
The detection items are as follows:
curing time: using 1000mW/cm2The curing condition of the glue is observed under different irradiation time by irradiating an energy UV-LED ultraviolet lamp, such as XC210 (the wavelength is 365nm) of IGE, and the time corresponding to the complete curing is taken as the curing time. For comparative example 1, the solution was left at room temperature after dipping, and the solvent was completely volatilized as a curing time.
Shore hardness: 2g of the cleaning glue is taken in a special mould, the UV-LED ultraviolet lamp, such as XC210 (with the wavelength of 365nm) of IGE, is used for curing by using UV energy of 2000-5000mj/cm2, and the hardness of the cured transfer printing film is detected by using a digital Shore durometer after the transfer printing film is kept stand for 24 hours. The greater the shore hardness number, the greater the hardness indication, while the hardness on the D scale is higher than on the a scale.
Dust removal performance: respectively scattering dust and particles on a glass sheet and a PC sheet with the thickness of 10mm multiplied by 20mm, slightly sticking the glass sheet and the PC sheet by using the solidified cleaning glue, and observing the surfaces of the glass sheet and the PC sheet under a microscope, wherein the glass sheet and the PC sheet pass through the microscope without impurity residues completely.
Adhesion properties: and (3) taking PC sheets with different weights, slightly pressing the cleaning rubber head on the surface of the sheet at an angle of 60 degrees, slightly lifting the rubber rod, observing whether the sheet is lifted along with the rubber rod, and recording the weight of the sheet.
| Serial number | Test 1 | Test 2 | Test 3 | Test 4 |
| Test method | Curing time | Shore hardness | Dust removal performance | Adhesion Properties |
| Example 1 | 4 seconds | A35 | By passing | 1g |
| Example 2 | 10 seconds | A52 | By passing | 2g |
| Example 3 | 3 seconds | A61 | By passing | 3g |
| Example 4 | 5 seconds | A65 | By passing | 4g |
| Example 5 | 5 seconds | A68 | By passing | 2g |
| Example 6 | 4 seconds | A70(D20) | By passing | 3g |
| Comparative example 1 | 2 hours | D40 | By passing | 6g |
| Comparative example 2 | 4 seconds | A62 | Do not pass through | <1g |
In some application scenarios, since the parts to be cleaned are difficult to fix, it is desirable to remove the impurities without taking up the parts when using the cleaning paste. In the comparison, we can see that [ comparative example 1 ] is a red glue which is generally used in the market, needs to be dried for a long time when being used, is not environment-friendly due to solvent volatilization, has high viscosity and limits the application of the red glue. And [ examples 1-6 ] the curing time is less than or equal to 10s and the time is short. In the composition of comparative example 2, polyvinyl acetate was lacking, and the dust removing ability was not satisfactory. From [ examples 1 to 6 ], we can also see that we can control the hardness and adhesion performance of the cleaning adhesive by adjusting the addition amounts of the multifunctional monomer and the polyvinyl acetate in the formula, so as to meet the requirements of various application scenarios.
