Embodiment 1

[0037] Example 1: The choice of ordinary microdermabrasion

[0038] The inventor selects the best formula by setting different formulas.

[0039] Recipe 1:

[0040] Solvent DMF: 10 parts;

[0041] Polyurethane with a modulus of 60: 1 part;

[0042] Modulus 240 Polyurethane: 1 part.

[0043] The preparation process can be completed by those skilled in the art according to the prior art, such as the following process:

[0044] 1. The preparation process of the polishing base cloth: the polishing base cloth is produced by the needle-punched non-woven fabric manufacturing process.

[0045] 2. Ordinary microdermabrasion preparation process:

[0046] 1) Fully impregnate the polishing base cloth with polyurethane.

[0047] 2) Put the semi-finished product into the coagulation tank, because the solvent DMF and water can be miscible in any proportion, so that a large amount of solvent DMF in the semi-finished product enters the water in the coagulation tank, so that the solvent D...

Embodiment 2

[0127] Embodiment 2: Preparation of single-sided wet-coated glass polishing multi-layer abrasive skin

[0128] 1) Place the polishing base cloth on the cloth laying table and fully impregnate it with polyurethane.

[0129] 2) The polishing base cloth fully impregnated with polyurethane enters under the precision coating knife, and the gap between the precision coating knife and the polishing base cloth fully impregnated with polyurethane is controlled, and the polishing base cloth fully impregnated with polyurethane advances at a constant speed. One side forms a layer of polyurethane coating. Those skilled in the art can complete this step through any available coating methods in the prior art.

[0130] 3) Enter the coagulation tank, because the solvent DMF and water can be miscible in any proportion, so that a large amount of solvent DMF in the semi-finished product enters the water in the coagulation tank, so that the solvent DMF in the semi-finished product is reduced, and...

Embodiment 3

[0139] Example 3: Preparation of wet coating using release paper.

[0140] 1) Place the release paper on the cloth table.

[0141] 2) Put the release paper under the precision coating knife, control the gap between the precision coating knife and the release paper, and the release paper advances at a constant speed, so that the wet-process polyurethane passes through the precision coating knife to form a layer of wet on one side of the release paper. French polyurethane coating.

[0142]3) Put the semi-finished product into the coagulation tank, because the solvent DMF and water can be miscible in any proportion, so that a large amount of solvent DMF in the semi-finished product enters the water in the coagulation tank, so that the solvent DMF in the semi-finished product is reduced, and the polyurethane solidifies.

[0143] 4) Enter the washing tank to wash away excess solvent.

[0144] 5) Enter the oven at a temperature of 110-150 degrees Celsius, and run in the oven for 1...

Abstract

The invention discloses a multi-layer buffing piece for glass polishing. The multi-layer buffing piece for glass polishing comprises a buffing piece for glass polishing and at least one dry-method polyurethane coating, wherein the buffing piece for glass polishing is prepared from the following formula of 8 parts of DMF; 2 parts of polyurethane with modulus of 60; and 2 parts of polyurethane withmodulus of 95. The invention further relates to a preparation method and application of the multi-layer buffing piece for glass polishing. A brush made of the multi-layer buffing piece for glass polishing can achieve the effects of thinning, fine polishing and sweeping of mobile phone glass at the same time, and therefore a thinning procedure, a fine polishing procedure and a sweeping procedure ofglass polishing in the prior art are combined into one procedure.

Description

technical field [0001] The invention relates to a multi-layer abrasive skin for glass polishing and its preparation and application. Background technique [0002] Glass polishing includes processes such as thinning, fine polishing and sweeping. In the prior art, the consumables used in these three processes are different. The main consumables used in the thinning process are pure polyurethane polishing leather with cells, the main consumables used in the fine polishing process are polyurethane polishing leather with polishing base cloth, and the main consumables used in the sweeping process are black damping cloth or carpet . [0003] In the prior art, the three processes of thinning, fine polishing and sweeping need to use different consumables and operate in stages. This is not only a cumbersome process, low efficiency, but also high cost of consumables. Contents of the invention [0004] Aiming at the technical defects and deficiencies existing in the prior art, the...
