  • The method of spraying paint off of CP, CA, TR90 material glasses frame to enhance the adhesion of paint film

    There are many kinds of materials for spectacle frames according to different needs. In order to obtain decorative and protective properties, the surface treatment methods of small spectacle frames are also different. In any case, the adhesion between the paint and the substrate in the painting determines the quality of the painting and the performance of the paint. CA, CP and TR90 are mainly used in plastic spectacle frames. Let’s take a look at how to solve the problem of paint peeling during spraying?

    Before analyzing the paint peeling problem of CA, CP and TR90 spectacle frame materials, we must first determine which material the spectacle frame belongs to, so as to provide targeted solutions to enhance adhesion. Let’s take a look first. The characteristics of the three materials and their application in eyeglass frames:

    TR90 material: polymer material with memory, ultra-light frame material, has the characteristics of super toughness, impact resistance and wear resistance, low friction coefficient, etc., which can effectively prevent the eyes and face from being damaged due to frame breakage and friction during exercise. s damage. CA material is widely used in daily eyeglass frames, sunglasses and earphone headbands: the chemical name is acetate fiber, which is commonly used in injection molding frames. Gloss, dimensional stability, good impact resistance, slightly less recovery. Easy to process and adjust. Acetate frames generally come from this material, especially black frames. CP material: The chemical famous car is propionic acid fiber, and the hydroxyl group in the cellulose molecule is a high polymer in propionic acid, which has good weather resistance and low temperature resistance. At present, the market of this material is mainly used for glasses, toys and various shells.

    Spectacle frames made of CA, CP, and TR90 are mainly spray-painted in the surface treatment, usually sprayed with PU paint or rubber paint, with one coating or multiple coating processes. However, in the actual spraying process, paint peeling or weak coating adhesion are also important problems that plague the spraying yield of the three materials. Because it needs to adapt to different application environments and frequencies of use, the tests on its paint coatings are also very strict, such as 100 grid tests, freezing tests, aging resistance tests, bending tests, knife cutting tests, etc. Therefore, when choosing a solution, in addition to the coating adhesion that needs to meet the standard, it must also pass the above test requirements. This is why the use of adhesion treatment agents is widely used to solve the problem of paint peeling of CA, CP, TR90 glasses frames.

    The main component of CA, CP, TR90 adhesion treatment agent is acrylic copolymer, which is a linear molecular structure. One end of the linear molecule can enter the inner layer of CA, CP, TR90 plastic and react with resin molecules to form molecular bonds, and at the same time form a layer of For the protective coating, the other end of the linear molecule is linked with the hydroxyl group in the topcoat to improve the adhesion of the topcoat. It can pass performance tests such as freezing, cutting, high and low temperature, sweat, and bending.
