Abstract

The invention relates to the technical field of abrasive tools and particularly relates to a high-toughness phenolic resin adhesive for abrasive paper, and a preparation method and application methodthereof. The abrasive paper is prepared by blending four components A, B, C and D, wherein the A component includes phenolic resin, polyurethane, and multifunctional amine additive, the B component iswater, the C component includes a silane coupling agent, a permeating agent, a defoaming agent, and a leveling agent, and the D component is filler. Compared with an abrasive paper adhesive in the prior art, the high-toughness phenolic resin adhesive only employs water as a solvent without any other organic solvents, so that during a curing process, volatilization of organic solvents is avoided and environmental pollution is greatly reduced. The preparation method is simple in process and low in production cost, and is suitable for large scale production. The adhesive is used for manufacturing the abrasive paper for abrasive, wherein an abrasive test result proves that compared with the adhesives in the prior art, the abrasive paper employing the adhesive in the invention is better in flexibility and is higher in abrasive efficiency.

Description

technical field [0001] The invention relates to the technical field of abrasive tools, in particular to a high-toughness phenolic resin binder for sandpaper, a preparation method and an application method thereof. Background technique [0002] Abrasives include coated abrasives and bonded abrasives. As an important coated abrasive, sandpaper is widely used in the polishing of paint surfaces, metals, and polishing of electronic products and precision instruments. The binder used in the traditional production of abrasive tools is mostly oily epoxy resin, which is expensive, and the solvent is organic solvents such as toluene, which will volatilize into the air during the curing process and seriously pollute the environment. [0003] With the improvement of environmental protection requirements, there are more and more researches on water-based sandpaper binders, such as using water-based phenolic resin or water-based epoxy resin to replace epoxy resin. However, there are stil...
