Embodiment Construction

[0008] A non-toxic coating formula, the coating components include thermoplastic phenolic resin, thermosetting phenolic resin, solvent and silane coupling agent, the proportion of each component is calculated in parts by weight: 136-138 parts by weight of thermoplastic phenolic resin, 42-44 parts by weight of thermosetting phenolic resin, 79-81 parts by weight of solvent, and 35-37 parts by weight of silane coupling agent.

[0009] In some embodiments, the solvent is methanol or ethanol or a mixture of the two solvents in any ratio.

[0010] In some embodiments, the silane coupling agent is 3-aminopropyltriethoxysilane.

[0011] The present invention adds a new component, 3-aminopropyltriethoxysilane coupling agent, to the traditional coating formula as an excellent adhesion promoter, which can improve the adhesion of the phenolic resin binder in the grinding wheel manufacturing process. Adhesion, so as to improve the bonding force of the mesh, sand and resin in the grinding ...

Abstract

The invention discloses a nonhazardous coating formula. The coating is prepared from, by weight, 136-138 parts of thermoplastic phenolic resin, 42-44 parts of thermoset phenolic resin, 79-81 parts of a solvent and 35-37 parts of a silane coupling agent. The nonhazardous coating formula has the advantages that the new ingredient 3-aminopropyltriethoxysilane coupling agent is added into a traditional coating formula and can improve the binding performance of a phenolic resin binding agent in the grinding wheel manufacturing process as an excellent binding promoter, and thus the binding force of mesh sheets in grinding wheels with sand and resin can be improved; grinding wheels made with the coating formula are high in wear resistance, the highest revolving speed of grinding wheels is increased by 10% or above, and thus the service life of grinding wheels is prolonged.

Description

technical field [0001] The invention relates to a coating formula, in particular to a non-toxic coating formula. Background technique [0002] The grinding wheel mesh is made of grinding wheel mesh cloth coated with phenolic resin and epoxy modified resin after drying and then die-cut. If necessary, it is laminated with non-woven fabric, black paper and plastic film. It has excellent tensile strength and flexural resistance , is the best reinforced substrate for various resin grinding wheels. In the process of resin grinding wheel processing, the superior coating performance of the grinding wheel mesh directly affects the service life and wear resistance of the grinding wheel. The traditional non-toxic coating formula is very single, which leads to weak bonding force between the mesh, sand and resin in the grinding wheel, and the combination is not tight, resulting in non-wear resistance and low service life of the grinding wheel. Contents of the invention [0003] The o...
