Problems solved by technology

This may hinder the cutting ability of the abrasive
Additionally, this can result in a reduced lifespan of the abrasive article, so the finish of the surface to be abraded may not be optimal
For example, paper has a relatively low tensile strength at break, which can lead to premature failure of a coated abrasive product with a paper backing before its abrasive surface has been fully utilized

Embodiment 1-5

[0099] The engagement coating is prepared by mixing a part of IR-651, 39.6 parts Sr 368d and 59.4 parts of SR 351.

[0100] By mixing 19.47 SR351, 12.94 SR 339, 3.08 parts SC24000, 1.93 A-174 TM 1.08 parts of TPO-L and 61.50 parts GC2500 were prepared from milling slurry (AS1).

[0101] The engagement coating is applied to the cork backing sheet and the abrasive slurry is applied to a polypropylene tool having a microcomposed surface, which is a desired reverse pattern desired by the surface of the formed abrasive. The coated tool is applied to the bonded coating to establish contact between the engaging coating and the slurry side of the tool. Then, by exposure to a 100% power D-type bulb, the tool side of the obtained laminate is exposed to ultraviolet radiation at the same time of 22 m / min. The tool is then removed from the fully cured molded abrasive coating on the bonded cork backing.

[0102] The process is repeated for each of Examples 1 to Example 5.

[0112] The engagement coating is prepared by mixing a part of IR-651, 39.6 parts Sr 368d and 59.4 parts of SR 351.

[0113] By mixing 56.49 parts of SR 351 and SR 368D, 1.99 parts of OX-50, 1.99 parts of A-174 and 38.57 serviles were mixed in a paddle mixer. 4 The first mixture is prepared.

[0114] 42 parts of the first mixture were then mixed with 58 parts of P180 with a paddle mixer.

[0115] The engaging coating is spread on a solid cork backing with a 20 micron rod. The slurry is then poured directly into a cork backing sample having a size of 100 cm × 20 cm, and spread the slurry as possible with a flat metal paving rod. The polypropylene tools of the matching length are placed on the abrasive slurry such that the reverse microcomputer surface desired by the molded abrasive surface is facing the abrasive slurry. Use the commercial name "3M501E special high temperature shielding tape" purchased from the 3M company of Sao Paulo, Minnesota, USA, sticks the cork backing and poly...

Abstract

The present disclosure relates to an abrasive article with a cork backing layer. In addition, the present disclosure relates to a method for producing abrasive articles comprising the cork backing layer.

Description

Technical field [0001] The present disclosure relates to an abrasive article having a soft wood backing layer. Further, the present disclosure relates to a method for producing an abrasive article comprising a cork backing layer. Background technique [0002] Abrasive articles, especially with coated abrasive articles, generally comprising an abrasive typically abrasive grain form, which is bonded to the backing using at least one adhesive layer. These abrasive articles are usually form a film, disk, belt, loop, can be adapted to grip with hand, fastened to the disc mosten machine, random track matte or other power tool and installed in the pulley, wheel Or matte block or reusable support pad on the drum. Abrasive articles can be used for sand mill, grinding or polishing, such as steel and other metals, composite materials, plastics, wood, imitation wood laminated materials, plastic fiberglass, leather, ceramic, stone, paint, coating, and other materials surface. [0003] The bac...
