specific Embodiment

[0018] Example 1, choosing a biaxially stretched polyethylene terephthalate film with a thickness of 100um as the substrate, the polyethylene terephthalate film is a polyester film with high flatness and strength,

[0019] Get the polyurethane resin that the weight proportion is 40 parts, 1.2 parts of polyisocyanate and 30 parts of butanone, xylene mixed solvent preparation mixed solution A, get the polyurethane resin that the weight proportion is 40 parts, 1.5 parts of polyisocyanate and 40 parts of methyl ethyl ketone and xylene mixed solvent prepare mixed solution B,

[0020] Apply the mixed liquid A to the substrate with a thickness of about 5umn by the method of mixed coating, and then use the electrostatic sand planting method to implant the abrasive grains into the resin layer of the matrix, pre-dry at 75°C for 25 minutes, and then use the Apply a layer of mixed solution B with a thickness of 4um to the surface of the dried plastic sand layer, pre-cure at 75°C for 50 mi...

Abstract

The invention relates to a preparation method of UEA116 ultraprecise ground belt. The method includes the following steps: (1) bi-orientated polyethylene terephthalate film is taken as a matrix; (2) mixed solution A and B are prepared by binding agent, cross linking agent and solvent; (3) the mixed solution A is coated on the matrix by adopting a roller coating method, grains are implanted into matrix resin bed by adopting a static sand planting method, the resin bed is dried by predrying treatment at 75-85 DEG C, then the mixed solution B is coated on the dried glue sand bed surface by adopting the roller coating method, the resin bed is hardened by precuring treatment at 75-85 DEG C, and finally polyester film abrasive belt is crossly linked at normal temperature, thus obtaining the ultraprecise ground belt. The invention adopts micro powder or nano grinding micro powder as grinding material, utilizes novel polyurethane resin material as the binding agent and hexamethylene diisocyanate as the cross linking agent, uses polyester film with extreme high evenness and strength as the matrix and adopts fine-processing method and novel coated abrasive, thus ensuring ultraprecise grinding and polishing.

Description

technical field [0001] The invention relates to a preparation method of UEA116 ultra-precision grinding belt. Background technique [0002] Traditional coated abrasive products are mainly composed of three parts, substrate, abrasive and binder, among which the substrate is the most important. It is a kind of grinding tool made of various paper bases and cloth bases, ordinary brown corundum or silicon carbide as abrasives, and phenolic resin as a binder. Due to the insufficient precision of paper and cloth, coated abrasive products are only suitable for general grinding and polishing. In recent years, with the development of science and technology, some industrial products have put forward newer and higher requirements for coated abrasives. Ordinary grinding can no longer meet the needs of the market, especially in the electronics industry, instruments, instrumentation industries, aviation, aerospace The industry's requirements for coated abrasive products are more serious ...
