Problems solved by technology

Most of the existing non-woven polishing wheels are made of epoxy system, which needs to be diluted with a large amount of volatile solvents (such as alcohol). For volatile solvents, if the recycling is not done properly, it is easy to cause organic volatiles to exceed the standard and fail to reach the standard. Green Production Requirements
There are also a small number of non-woven polishing wheels that are produced using polyurethane systems, using the prepolymer method. The prepolymers that have been synthesized are purchased and then mixed with abrasives, curing agents and other materials to make polishing wheels, but usually they also need to be diluted with organic solvents. Still need Procedures for the recovery and treatment of organic solvents

Embodiment Construction

[0024] Aiming at the shortcomings of the non-woven polishing wheels used in the prior art, the present invention proposes a solvent-free non-woven polishing wheel and a preparation method thereof, which solve the problem of the existing epoxy system non-woven polishing wheels or polyurethane prepolymers. The non-woven polishing wheel of the method needs to be diluted with an organic solvent, which causes the problem of organic solvent volatilization in the preparation process.

[0025] The solvent-free type non-woven polishing wheel of the present invention comprises 80-120 parts of polyisocyanate, 50-150 parts of oligomer polyol, 5-25 parts of chain extender, 4-15 parts of cross-linking agent, 150-300 parts of abrasive, 5-20 parts of toner, and 10-50 parts of lubricant; in order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, three specific embodiments will be used for detailed description below.

Abstract

The invention provides a solvent-free type non-woven polishing wheel, comprising nylon fiber non-woven fabric and wear-resistant glue coated on the nylon fiber non-woven fabric, 80-120 parts of polyisocyanate and 50-120 parts of oligomer polyol 150 parts, 5-25 parts of chain extender, 4-15 parts of cross-linking agent, 150-300 parts of abrasive, 10-50 parts of lubricant, using the traditional manufacturing method of superimposed wheel, the wear-resistant glue is applied to nylon fibers Lamination wheels are prepared on non-woven fabrics. The production and preparation process of the solvent-free non-woven polishing wheel of the present invention does not need to add solvent, and is a green non-woven polishing wheel production process. At the same time, the solvent recovery process is reduced, the processing cost is saved, and the prepared polishing wheel is also It has the advantages of good wear resistance, elasticity and high temperature burn resistance.

Description

technical field [0001] The invention relates to the technical field of non-woven polishing wheels, in particular to a solvent-free non-woven polishing wheel and a manufacturing method thereof. Background technique [0002] The polishing wheel is used for polishing the workpiece surface or coating. According to the different main materials, polishing wheels are divided into non-woven polishing wheels, cotton polishing wheels, etc. Most of the existing non-woven polishing wheels are made of epoxy system, which requires a large amount of volatile solvents (such as alcohol) to dilute. For volatile solvents, if the recovery and treatment are improper, it is easy to cause the organic volatiles to exceed the standard and fail to reach the standard. requirements for green production. There are also a few non-woven polishing wheels produced by polyurethane system. The prepolymer method is used. The prepolymer that has been synthesized is purchased and then mixed with abrasives, cur...
