Abstract
The utility model relates to a grinding disc substrate manufactured by organic chemical fibers, which comprises a grid cloth layer made of the organic chemical fibers, wherein the back side of the grid cloth is provided with a glue leakage prevention back paper layer, the center of the grinding disc substrate is provided with a center hole, and the front side and the back side of the center hole are respectively provided with a metal gasket. The substrate is made into elastic grinding disc products, and the elastic grinding disc products can be recycled to be converted into petroleum products such as lightweight oil, heavy oil, carbon black and the like by utilizing a petroleum cracking process technology after being used to a scraped degree. The environment pollution is reduced, and certain economic recovery benefits are realized. Certain economic benefits are realized, and severe environment pollution and occupational disease harm to the bodies of workers generated during making the substrate by other materials in the prior art can also be effectively reduced.
Description
Technical field
The utility model belongs to the grinding tool technical field, is specifically related to the mill matrix that a kind of organic chemistry fiber is made.
Background technology
Common discoid coated abrasive tool " Circular back-plate for carrying flexible abrasive material " mainly is that abrasive material or emery cloth piece are adhered on the matrix.During work, matrix carrying abrasive material is rotated grinding work piece.This series products adopts fiberglass braided screen cloth always in the world at present, perhaps is pressed into thick and heavy cardboard with textile fiber and carries out several method such as injection moulding with engineering plastics and make the mill matrix.
For many years, though the mill matrix that adopts above-mentioned material to make is used widely, all exist insurmountable defective on coated abrasive tool.For example the injection molding of plastics matrix is heated and very easily is out of shape, the low i.e. distortion of making moist of pure cotton fiber millboard matrix tensile strength, and the matrix made from glass fibre, though intensity is big, heat-resisting and indeformable, but when the use of grinding tool finished product is made in the neutralization of manufacturing matrix process, swim in airborne raphioid fiber thing worker's respiratory tract and lung are polluted, and thrust skin and cause itch pain and occupational diseases such as erythema, its consequence is very serious.And the matrix output maximum that exactly this glass fibre is made is most widely used.Industrially developed country notices the serious consequence of this contamination phenomenon for a long time, expressly legislation forbids to produce home this kind product, be unable to do without the demand of mill again, so then mill matrix that the made in China glass fiber mesh of a large amount of buyings is made, go to this country to adhere to the emery cloth piece and make mill, marry again pollution sources, cause the come heavily contaminated of this series products of China environment.
For a long time, nobody works out and can solve the mill matrix that the glass fibre pollution can reach glass fiber strength and performance again always.Mill matrix manufacturing technology is rested in the technical merit state that can't break through.
The utility model content
The purpose of this utility model is to solve the aforementioned problems in the prior, the mill matrix that provides a kind of organic chemistry fiber to make.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The mill matrix that organic chemistry fiber of the present utility model is made, this mill matrix includes the grid layer of cloth that the chemical machine fiber is made, be provided with anti-strike-through backing paper layer at the back side of grid cloth, be provided with centre bore, be respectively equipped with metal washer at the front and back of centre bore at mill matrix center.
The grid layer of cloth that described grid layer of cloth Fypro boundling is interwoven.
The grid layer of cloth that described grid layer of cloth is interwoven for polyethylene terephthalate's collection of filaments.
The grid layer of cloth that described grid layer of cloth is interwoven for polyethylene terephthalate's collection of filaments.
The preparation method of the mill matrix that organic chemistry fiber of the present utility model is made is as follows:
(1) engineering macromolecular material (as polyamide, polyethylene terephthalate, polypropylene nitrile etc.) is at first carried out fusion, spray silk, setting and make the boundling fiber, carry out surface-active-treatment again, braiding becomes plane net shape fabric then.
(2) reticulated that will handle carries out carrying out the heated drying setting after macromolecule resin binding agent (as modified epoxy, phenolic aldehyde, the polyamino resin binding agent) dip-coating.
(3) reticulated of heat drying setting is cut into slices, suppressing heat is solidified to form discoid matrix, can carry out surface coating stick and abrasive material or emery cloth piece and become coated abrasive tool for the producer---Circular back-plate for carrying flexible abrasive material.
Because the utility model adopts the pure chemistry fiber to make net dish matrix, the production process clean and safe produces when having solved employing glass fibre making mill matrix and swims in the healthy drawback of airborne raphioid fiber thing injury operating personnel.The pure chemistry fibrous web-like matrix that the utility model is made, its appearance and size be logical fully enough to meet the standards such as security intensity, elasticity, use linear velocity of national standard and regulation.
Matrix make the Circular back-plate for carrying flexible abrasive material product use scrap after, utilize the petroleum cracking technology, can reclaim and be converted into petroleum product, for example light oil, mink cell focus and carbon black etc.Reduce environmental pollution and have certain economic to reclaim benefit.Not only have certain economic benefits, can also effectively alleviate serious environmental pollution that present this kind matrix produced with other materials and the occupational disease of workman's health is injured when making.

The specific embodiment
The mill matrix that the organic chemistry fiber of present embodiment is made as depicted in figs. 1 and 2, this mill matrix is straight circular discoid, this mill matrix includes the grid layer of cloth 1 that the chemical machine fiber is made, be provided with anti-strike-through backing paper layer 2 at the back side of grid cloth 1, be provided with centre bore at mill matrix center, be provided with metal washer 3 in the front of centre bore, be respectively equipped with metal washer 4 at the back side of centre bore.
Described grid layer of cloth is that 4-7 strata nylons grid cloth that interweaves forms with adhesive bond compacting, and the grid cloth order number that interweaves is 5-12 orders.
The mill matrix that the organic chemistry fiber of present embodiment is made as shown in Figure 3 and Figure 4, this mill matrix be straight and backward the elevation angle be 9 the degree circular discoids, this mill matrix includes the grid layer of cloth 1 that the chemical machine fiber is made, be provided with anti-strike-through backing paper layer 2 at the back side of grid cloth 1, be provided with centre bore at mill matrix center, be provided with metal washer 3 in the front of centre bore, be respectively equipped with metal washer 4 at the back side of centre bore.
