Abstract

A glass fiber web cloth sand plate comprises a glass fiber web cloth, an upper sand grain layer and a lower sand grain layer, wherein an installation fixation hole is arranged in the center of the glass fiber web cloth and the upper sand grain layer covers the upper surface of the glass fiber web cloth and the lower sand grain layer covers the lower surface of the glass fiber web cloth. The glass fiber web cloth sand plate has features of not-easy breakage, good safety, high thermal diffusivity and high process quality.

Description

The glass fiber mesh emery disc

Technical field

The utility model belongs to a kind of emery disc.

Background technology

Existing emery disc, generally include red steel paper disc, abrasive material, the red steel paper matrix is hunchbacked shape, its center is provided with and installs and fixes the hole, the medial surface of described red steel paper disc is laid one deck abrasive material by the even bonding layer of glass grid cloth of resin adhesive on the fiberglass gridding cloth of red steel paper disc outer ring.

The security in use of existing emery disc is not high, and general linear velocity is between 70～80m/s, and use is broken easily and hurted sb.'s feelings on pneumatic tool; The vulcan fibre emery disc adopts water-soluble bond, and sand grains comes off easily and is not durable, and thermal diffusivity is not high, and the workpiece of burning easily causes the workpiece gloss degree bad; Vulcan fibre has certain corrosivity in polishing, adheres to surface of the work easily.

Summary of the invention

In order to overcome the breaking easily of existing vulcan fibre emery disc, security is not high, thermal diffusivity is not high, crudy is relatively poor deficiency, the glass fiber mesh emery disc that the utility model provides a kind of and is not easy to break, security is good, thermal diffusivity is high, crudy is high.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of glass fiber mesh emery disc, described emery disc comprises glass fiber mesh, goes up sand grains layer and following sand grains layer, the center of described glass fiber mesh is provided with and installs and fixes the hole, and the upper surface of described glass fiber mesh covers goes up the sand grains layer, and the lower surface of described glass fiber mesh covers sand grains layer down.

Further, the upper surface of described glass fiber mesh is coated with and is covered with the phenolic resin binder layer, and described going up covers the described sand grains layer of going up on the phenolic resin binder layer; The lower surface of described glass fiber mesh applies phenolic resin binder layer down, covers described sand grains layer down on the described phenolic resin binder layer down.

Technical conceive of the present utility model is: adopt glass fiber mesh, the structure of sand is planted on the two sides, and adopts thermoplasticity and thermosetting phenolic resin bond, fiber and sand grains are in conjunction with firm and sharp, and wearability is good, good permeability, in use be not easy the workpiece of burning, the surface of the work glossiness is good.

Anti-bending strength improves a lot with respect to prior art, in use is fit to select for use different angles to reach different polishing effects;

Glass fiber mesh is closely linked with sand grains as matrix, wears away with sand grains in the use, has certain grindability, does not have corrosivity, can not corrode surface of the work.

The beneficial effects of the utility model mainly show: be not easy to break, security is good, thermal diffusivity is high, crudy is high.

Description of drawings

Fig. 2 is the sectional view of Fig. 1;

Fig. 3 is the schematic diagram of glass fiber mesh.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to Fig. 1～Fig. 3, a kind of glass fiber mesh emery disc, described emery disc comprises glass fiber mesh 1, goes up sand grains layer 2 and following sand grains layer 3, the center of described glass fiber mesh 1 is provided with and installs and fixes hole 4, the upper surface of described glass fiber mesh 1 covers goes up sand grains layer 2, and the lower surface of described glass fiber mesh 1 covers sand grains layer 3 down.

The upper surface of described glass fiber mesh is coated with and is covered with the phenolic resin binder layer, and described going up covers the described sand grains layer of going up on the phenolic resin binder layer; The lower surface of described glass fiber mesh applies phenolic resin binder layer down, covers described sand grains layer down on the described phenolic resin binder layer down.

The glass fiber mesh of present embodiment adopts 5～14 orders, and density is 125～380g/m ³, wherein the phenolic resin binder layer comprises the mixture of thermosetting phenolic resin, novolac resin, epoxy resin and calcium carbonate, the sand grains in last sand grains layer and the following sand grains layer adopts white fused alumina, carborundum etc.

Be coated in the upper and lower surface of glass fiber mesh at first with the glass fiber mesh punching, and with pre-configured phenolic resin binder, and plant sand, again through oven dry, shaping moulding.
