A kind of preparation method of varnish grinding sand disc

Abstract

The invention discloses a preparation method of a lacquer grinding sand plate. The preparation method specifically comprises the following steps of: adding a silicon carbide grinding material, a photo-curing adhesive, a diluent, a photo-initiator and auxiliaries into a container according to a proportion, and carrying out high-temperature lucifugal dispersion to form silicon carbide slurry; coating the qualifiedly dispersed silicon carbide slurry in a mould with a three-dimensional grinding material structure through gravure; pasting a PET base material on the mould, and irradiating the mouldby adoption of ultraviolet light so as to ensure that the slurry is cured and transferred onto the base material and then a repeatedly arrayed three-dimensional module structure is formed; heating andcuring the preliminarily formed module so as to obtain a three-dimensional grinding sand plate. The prepared grinding sand plate has three-dimensional silicon carbide grinding material, has good self-sharpening performance when being used for polishing flaws and damaged layers of lacquers, and is capable of greatly improving the lacquer polishing effect.

Description

technical field [0001] The invention relates to the technical field of workpiece grinding, in particular to a preparation method of an abrasive disc used for grinding the paint surface layer of a workpiece. Background technique [0002] High-grade lacquer surfaces are widely used. Suitable lacquer surfaces not only have a decorative effect on the body, but more importantly, can protect and enhance functionality. For example, in musical instruments, high-end furniture, automobiles, ships, yachts, aerospace equipment, etc., High-grade lacquer finishes play an increasingly important role. During the spraying process, there may be defects such as unevenness and local blemishes, which affect the appearance and its protective function. The later use process will also cause local damage due to the external environment, and the paint surface needs to be partially polished. In the early days, the polishing of paint surfaces was mostly done by combining dry sandpaper and polishing pa...

During the spraying process, the paint may have defects such as unevenness and local defects, which will affect the appearance and its protective function. The later use process will also cause local damage due to the external environment, and the paint surface needs to be partially polished

In the early days, the polishing of the paint surface was mostly processed by a combination of dry sandpaper and polishing paste, which was low in efficiency, poor in treatment effect, and cumbersome to operate
