Abstract

The invention discloses a crack-proof treatment method for an abrasive paper base material. The crack-proof treatment method comprises the following steps that (1) the surface of the abrasive paper base material is completely polished, flushed with flowing water twice and then flushed with absolute ethyl alcohol twice, and then the flushed abrasive paper base material is steeped in warm water for 10 min, wherein flushing with the flowing water is conducted for 3 min every time, and flushing with the absolute ethyl alcohol is conducted for 2-3 min every time; (2) the a crack-proof agent and magnetized water are uniformly mixed according to the mass ratio being 3:1, and a crack-proof agent solution is obtained; and (3) the steeped abrasive paper base material obtained in the step (1) is coated with the crack-proof agent solution obtained in the step (2), and secondary coating is conducted after the surface of the abrasive paper base material is dry. The shaping shrinkage cracking property of the abrasive paper base material prepared by the crack-proof treatment method is greatly lowered; and when a flat band method is adopted for testing, the shaping shrinkage cracking total weight value of the abrasive paper base material is reduced by 60-80% than that of ordinary kraft paper in the market.

Description

technical field [0001] The invention relates to the field of anti-crack treatment of sandpaper substrates, and specifically designs a method for anti-crack treatment of sandpaper substrates. Background technique [0002] As a grinding tool, sandpaper has been widely used in various fields. As the application becomes more and more extensive, the requirements for sandpaper are getting higher and higher, such as the need for excellent crack resistance, but the sandpaper currently on the market generally reaches Less than this requirement, the crack resistance is poor, which is mainly caused by the poor crack resistance of the sandpaper substrate. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems. [0004] In order to realize these purposes and other advantages according to the present invention, a kind of anti-crack treatment method of sandpaper base material is provided, comprising the following steps:...
