Embodiment 1～3

[0038] Provide semi-finished products including PC board substrate, hot melt adhesive layer, PET substrate and hot melt adhesive primer layer;

[0039] Mix the materials in the formula shown in Table 1, and disperse them in the dark by ultrasonic to form a slurry;

[0040] The dispersed slurry is placed in a concave structure mold with a certain regular arrangement by roller coating;

[0041] Attach the primer layer of the above-mentioned semi-finished product to the mold, and irradiate it with ultraviolet light, so that the slurry is cured and transferred to the substrate to form a repeatedly arranged grinding block structure;

[0042] The molded product is heated and solidified to obtain an abrasive product with a three-dimensional structure.

Abstract

The invention provides a three-dimensional grinding material. The three-dimensional grinding material comprises a substrate, an adhesive layer which is compounded on the substrate, a base material which is compounded on the adhesive layer, a bottom adhesive layer which is compounded on the base material, and a plurality of grinding blocks which are arranged on the bottom adhesive layer; a gap is reserved between every two adjacent grinding blocks; the grinding blocks are formed by curing a mixture, wherein the mixture is comprises 20 to 40 weight percent of a photo-curing adhesive, 10 to 30 weight percent of a thermo-curing adhesive, 0.1 to 3 weight percent of a photoinitiator, 0.1 to 3 weight percent of a thermal initiator, 0.1 to 3 weight percent of a thermo-curing agent, 30 to 70 weightpercent of a grinding material, and 1 to 5 weight percent of an auxiliary agent, wherein the photo-curing adhesive is selected from polyurethane acrylate resin; and the thermo-curing adhesive is selected from epoxy resin. The invention also provides a preparation method of the there-dimensional grinding material. The three-dimensional grinding material which is prepared from the polyurethane acrylate resin and the epoxy resin serving as adhesives provided by the invention is slow in loss and long in service life.

Description

technical field [0001] The invention belongs to the technical field of abrasive materials, in particular to a three-dimensional abrasive material and a preparation method thereof. Background technique [0002] The rapid development of high technology and the upgrading of product manufacturing mean that the demand for component processing is getting higher and higher, and various new materials have also been more and more widely used, such as glass, ceramics, metals, plastics and other materials are used in electronics High-precision surface processing industries such as automobiles, LCDs, etc. have also put forward higher requirements for grinding and polishing consumables. [0003] Coated abrasives are widely used in grinding and polishing, but for processing fields with special requirements, such as electronic product shell polishing, automotive paint polishing, liquid crystal panels, hard and brittle materials processing, etc., traditional coated abrasives are easy to coa...
