Existing power tools, including polishers, grinders, and the like, operate using abrasive tools that are widely used in the food processing, paper manufacturing, and non-metallic materials such as ceramics, glass, stone, plastics, rubber, wood, in addition to being widely used in the machine manufacturing and other metal processing industries.

For some polishing industries, nylon 6 is most commonly used to be made into nylon wheels, namely, nylon 6 is stirred and foamed to form a layer of fibrous material, and then multiple nylon 6 layers are glued together by using an adhesive to form a grinding tool, so that the wear-resistant characteristic is formed.

Disclosure of Invention

The invention aims to provide a novel grinding tool abrasive material structure to solve the problems of insufficient wear resistance and short service life in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel grinding apparatus abrasive material structure, includes the nylon stratum basale more than the at least one deck, arbitrary one side or both sides are laminated on the nylon stratum basale/down have the one deck extrude into the wear-resisting nylon layer of solid solution filiform structure by the extruding machine bistrique, still laminated one deck cementing layer on the wear-resisting nylon layer.

The further technical scheme is that the nylon substrate layer and the wear-resistant nylon layer are both made of nylon 6, and are commonly used polishing abrasive tool materials.

The further technical scheme is that the adhesive layer is an acrylic adhesive layer which is a common adhesive and used for adhering the upper nylon substrate layer and the lower nylon substrate layer.

The further technical scheme is that the thickness of the nylon substrate layer is larger than that of the wear-resistant nylon layer, the nylon substrate layer is mainly polished, and the wear-resistant nylon layer is added to increase the wear resistance of the nylon substrate layer.

The invention also provides a manufacturing method of the novel grinding tool abrasive material structure, which comprises the following steps: 1) firstly, opening, cotton mixing, carding and lapping nylon 6 material particles to form a nylon substrate layer with a 3-4 m wide-width silk net structure; 2) then, the small blocks are formed by slicing the nylon substrate layer; 3) the nylon 6 material particles are placed into an extrusion molding machine and heated at high temperature to form flowable liquid, and the flowable liquid is typeset and extruded into a solid solution filamentous structure through a screw sleeve grinding head and is uniformly coated on a nylon substrate layer to form a wear-resistant nylon layer; 4) and then uniformly spraying a layer of cementing layer on any one side or two sides of the upper and lower sides of the nylon substrate layer after the nylon substrate layer is well laminated, and finally, adhering the other nylon substrate layer on the cementing layer.

Compared with the prior art, the invention has the beneficial effects that: the novel grinding tool abrasive structure adopts the abrasion-resistant nylon layer which is extruded into the solid solution filamentous structure by the grinding head of the extruding machine to be coated on the nylon substrate layer, so that the tension of the longitude and the latitude of the whole grinding tool abrasive can be increased, and the abrasion resistance is increased by at least 3 times.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, an embodiment of the present invention includes: a novel grinding tool abrasive material structure comprises at least more than one nylon substrate layer 1, wherein a wear-resistant nylon layer 3 which is extruded into a solid solution filamentous structure by a grinding head of an extruding machine is coated on any one side or two sides of the nylon substrate layer 1, and a cementing layer 2 is further coated on the wear-resistant nylon layer 3.

The nylon substrate layer 1 and the wear-resistant nylon layer 3 are both made of nylon 6 and are common polishing abrasive materials. The glue layer 2 is an acrylic glue layer, which is a common glue used for gluing the upper nylon substrate layer 1 and the lower nylon substrate layer 1. The thickness of nylon stratum basale 1 is greater than 3 thicknesses on wear-resisting nylon layer, and the main polishing lies in nylon stratum basale 1, increases wear-resisting nylon layer 3 in order to increase its wearability.

The manufacturing principle is as follows: 1) firstly, opening, cotton mixing, carding and lapping nylon 6 material particles to form a nylon substrate layer 1 with a 3-4 m wide-width silk net structure; 2) then cutting the nylon substrate layer 1 into small round blocks through nylon chips; 3) the nylon 6 material particles are placed into an extrusion molding machine and heated at high temperature to form flowable liquid, and the flowable liquid is typeset and extruded into a solid solution filamentous structure through a screw sleeve grinding head and is uniformly coated on the nylon substrate layer 1 to form a wear-resistant nylon layer 3; 4) then one deck cementing layer 2 is evenly sprayed on arbitrary one side or both sides about nylon stratum basale 1 after the laminating, finally can other nylon stratum basale 1 adhesion on cementing layer 2.

As shown in fig. 2, nylon substrate layer 1 can be the mutual adhesion in both sides, two-layer nylon substrate layer 1 carries out the veneer through cementing layer 2 each other, wear-resisting nylon layer 3 is inside and outside cementing layer 2, wear-resisting nylon layer 3 just has stronger adhesion originally on nylon substrate layer 1 forming the flowing liquid cladding, in addition cementing layer 2 can be in the same place firm adhesion between the nylon substrate layer 1 from top to bottom, indirectly also increased its wearability, and nylon substrate layer 1 is the ordinary polishing nylon cotton on the market, its technology is also ordinary preparation technology, the circular chunky polishing nylon cotton of in-service use is at least by one deck nylon substrate layer 1 and two-layer wear-resisting nylon layer 3 through cementing layer 2 cladding, as shown in fig. 3, become the real object schematic diagram of solid solution type filiform structure even cladding on nylon substrate layer 1 for wear-resisting nylon layer 3.
