Embodiment 1

[0023] A method for preparing a high-precision camera lens polishing damping cloth, comprising the following steps:

[0024] a. Add DMF solvent and lignocellulose to the container first, and fully stir with a mixer, then add polyurethane resin, additives, anti-fungal agent and color paste, then use a vacuum defoamer to defoam, and finally use a 40-mesh filter to filter Filter to obtain polyurethane mixed slurry;

[0025] b. The base fabric is unrolled and immersed in the immersion tank through the cloth storage rack. In the immersion tank, in addition to clear water, 1% anionic surfactant should be added, and then the water in the base fabric should be squeezed dry with a squeeze roller, and then passed through the ironing wheel. Iron the base cloth to half dry;

[0026] c. Then the treated base cloth passes through the coating table, and the slurry mixture is evenly coated on the base cloth by the coating knife coating method, and then enters the coagulation liquid in the co...

Embodiment 2

[0030] a. Add DMF solvent and lignocellulose to the container first, and fully stir with a mixer, then add polyurethane resin, additives, anti-fungal agent and color paste, then use a vacuum defoamer to defoam, and finally use a 40-mesh filter to filter Filter to obtain polyurethane mixed slurry;

[0031] b. The base fabric is unrolled and immersed in the immersion tank through the cloth storage rack. In the immersion tank, in addition to clear water, 1% anionic surfactant should be added, and then the water in the base fabric should be squeezed dry with a squeeze roller, and then passed through the ironing wheel. Iron the base cloth to half dry;

[0032] c. Then the treated base cloth passes through the coating table, and the slurry mixture is evenly coated on the base cloth by the coating knife coating method, and then enters the coagulation liquid in the coagulation tank for solidification;

[0033] d. After the polyurethane mixed slurry is completely solidified, it is ful...

Embodiment 3

[0036] a. First add DMF solvent and lignocellulose into the container, and stir it fully with a mixer, then add polyurethane resin, additives, anti-fungal agent and color paste, then use a vacuum defoamer to defoam, and finally use a 50-mesh filter to filter Filter to obtain polyurethane mixed slurry;

[0037] b. The base fabric is unrolled and immersed in the immersion tank through the cloth storage rack. In the immersion tank, in addition to clear water, 1% anionic surfactant should be added, and then the water in the base fabric should be squeezed dry with a squeeze roller, and then passed through the ironing wheel. Iron the base cloth to half dry;

[0038] c. Then the treated base cloth passes through the coating table, and the slurry mixture is evenly coated on the base cloth by the coating knife coating method, and then enters the coagulation liquid in the coagulation tank for solidification;

[0039] d. After the polyurethane mixed slurry is completely solidified, it i...

Abstract

The invention relates to the technical field of preparation of damping clothes, specifically to a preparation method of a polishing cloth for polishing and grinding a lens of a high-precision camera.The method comprises the following steps: preparing mixed polyurethane slurry; dipping in water; ironing; covering; solidifying; fully washing with water; drying and sizing; coiling; polishing; separating, and the like. According to the method, the raw material components of the mixed polyurethane slurry are reasonable; the added additive is prepared by mixing glycerinum, ethidene diamine and liquid paraffin; glycerinum and ethidene diamine are both chain extenders and can react with a functional group on a polymer chain to extend a molecule chain and increase the molecular weight, thus the polyurethane is promoted to size, and the stress at definite elongation and the wear resistance of the damping cloth can be greatly improved; glycerinum has melting prompting effect and coordinates withthe liquid paraffin to act to reduce the surface tension of the mixed polyurethane sizing, so that the leveling property and the uniformity can be improved, and the surface of the prepared damping cloth is flat, smooth and uniform; the waterproofing and dirt preventing performances of the damping cloth are improved by the liquid paraffin.

Description

technical field [0001] The invention relates to the technical field of damping cloth preparation, in particular to a preparation method of a damping cloth for high-precision camera lens polishing. Background technique [0002] A camera is a device that uses the principle of optical imaging to form an image and uses a film to record the image. It is an optical device used for photography. In modern social life, there are many devices that can record images. The main components of the camera include: imaging components, darkrooms, imaging media and imaging control structures. The imaging components can perform imaging. A lens group usually made of optical glass lenses is called a lens. Small holes, electromagnetic coils, etc. also play the role of a lens on specific equipment. The imaging medium is responsible for capturing and recording images. The darkroom is the lens and imaging. Provide a connection between the medium and protect the imaging medium from interference, and ...
