Abstract
The invention discloses a coating formula for a mesh sheet, which includes thermoplastic phenolic resin, thermosetting phenolic resin, a solvent and a silane coupling agent according to the weight part ratio as follows: 90-100 parts of the thermoplastic phenolic resin, 10-12 parts of the thermosetting phenolic resin, 45 parts of the solvent and 4-5 parts of the silane coupling agent. In the invention, a new component, 3-aminopropyltriethoxysilane coupling agent, is added to a conventional coating formula, wherein the coupling agent, as an excellent binding accelerant, can improve the binding property of a phenolic resin binder during production process of a grinding wheel, thereby improving the binding force of a mesh sheet in the grinding wheel and sand and resin. The grinding wheel prepared with the coating has strong wear resistance and is increased in maximum revolving rotational rate by more than 10%, thereby prolonging the service life of the grinding wheel.
Description
Technical field
The present invention relates to a kind of coating formula is and in particular to a kind of coating formula of mesh sheet.
Background technology
Emery wheel mesh sheet be phenolic resin is coated with using emery wheel screen cloth, epoxy modified resin is punched and forms after drying, when needing
Laminating non-woven fabrics, black paper and plastic sheeting, have excellent tensile strength and warp resistance performance, are the optimal increasings of various resin wheels
Strong basis material.In the resin wheel course of processing, the coating performance of emery wheel mesh sheet is superior directly affect emery wheel service life and
Tear resistance.The coating formula of traditional mesh sheet is very single, leads to emery wheel backing wire piece weak with the adhesion of sand and resin, in conjunction with not
Closely, lead to the not wear-resisting of emery wheel, service life is low.
Content of the invention
It is an object of the invention to provide a kind of coating formula of mesh sheet, solve one of above-mentioned prior art problem or many
Individual.
Unresolved above-mentioned technical problem, the technical solution used in the present invention is: a kind of coating formula of mesh sheet, described coating
Composition includes thermoplastic phenolic resin, thermosetting phenolic resin and solvent, and its innovative point is: also includes silane coupler, respectively
The proportioning of component is in parts by weight: thermoplastic phenolic resin 90～100 weight portion, thermosetting phenolic resin 10～12 weight
Part, solvent 45 weight portion, silane coupler 4～5 weight portion.
In some embodiments, solvent is any proportioning mixture of methanol or ethanol or two kinds of solvents.
In some embodiments, silane coupler is 3- aminopropyl triethoxysilane.
It is an advantage of the current invention that: the present invention is in traditional coating formula, adds a kind of new component 3- aminopropyl three
Ethoxysilane coupling agent, as excellent adhesive accelerant, can improve phenolic resin adhesive in emery wheel manufacture process
Cohesive, thus improving the adhesion of emery wheel backing wire piece and sand and resin, the emery wheel made using this coating formula, it is wear-resisting
Property strong, emery wheel highest revolution rotating speed improves more than 10%, thus extending the service life of emery wheel.
Specific embodiment
A kind of coating formula of mesh sheet, described coating composition includes thermoplastic phenolic resin, thermosetting phenolic resin, solvent
And silane coupler, the proportioning of each component is in parts by weight: thermoplastic phenolic resin 90～100 weight portion, thermosetting
Phenolic resin 10～12 weight portion, solvent 45 weight portion, silane coupler 4～5 weight portion.
In some embodiments, solvent is any proportioning mixture of methanol or ethanol or two kinds of solvents.
In some embodiments, silane coupler is 3- aminopropyl triethoxysilane.
The present invention is in traditional coating formula, adds a kind of new component 3- aminopropyl triethoxysilane coupling agent,
As excellent adhesive accelerant, the cohesive of phenolic resin adhesive in emery wheel manufacture process can be improved, thus improving sand
Wheel backing wire piece and the adhesion of sand and resin, the emery wheel made using this coating formula, its wearability is strong, and emery wheel highest is turned round
Rotating speed improves more than 10%, thus extending the service life of emery wheel.
The above be only the optimal way of the present invention it is noted that to those skilled in the art, not
On the premise of departing from the invention design, some similar deformation and improvement can also be made, these also should be regarded as the present invention
Protection domain within.
