Embodiment 1-4

[0110] Embodiment 1-4 (preparation of bonding matrix)

[0111] According to the ingredients and their amounts listed in Table 2, the bonding matrix was prepared through the following steps.

[0112] Step 1: Add the ingredients to a CAModel#LA1A mixer (the mixer can be purchased from Cott Turbo Mixer Inc);

[0113] Step 2: Stir for 30 minutes at a temperature of 30° C. and a rotation speed of 400 RPM to mix the ingredients uniformly to obtain a bonding matrix.

Embodiment 5-13 and comparative Embodiment C1-C4

[0117] "Preparation of Abrasives":

[0118] According to the composition listed in Table 3 and its consumption, through the following steps, prepare abrasive:

[0119] Under the condition of no more than 30°C, use a CA Model#LA1A agitator (the agitator can be purchased from Scott Turbo Mixer Inc), and the rotation speed is under the condition of 400RPM to disperse the abrasive particles evenly in the bonding matrix, Get abrasive.

[0120] "Preparation of abrasive parts":

[0121] Apply the abrasive evenly to the Figure 2A and Figure 2B On the shown PP (polypropylene) mold, the PP mold is manufactured by micro-replication technology, the width of the PP mold is 200 mm, and the PP mold has a square cavity structure. The square mold cavity includes a plurality of regularly arranged grooves, the bottom surfaces of these grooves are parallel to the cross section of the groove along the horizontal direction and have the same area, and the bottom area of ​​these grooves is 1.69...

Abstract

An abrasive comprising abrasive particles and an adhesive matrix is provided, with the abrasive particles being distributed in the adhesive matrix, wherein the abrasive particles comprise aluminum hydroxide abrasive particles, and the adhesive matrix comprises a triacrylate, a diacrylate and an initiator. The abrasive article prepared using the abrasive of the present invention has proper wear resistance and can be used to a clean LCD panel surface without scratching the ITO coating on an LCD panel surface.

Description

technical field [0001] The invention relates to the field of grinding, in particular to an abrasive material, an abrasive piece and a method for preparing the abrasive piece. Background technique [0002] In the production process of the LCD screen, there is a step of cleaning the surface of the LCD screen. In this step, scrapers or abrasive belts are often used to clean impurities or glass debris on the surface of the LCD screen. [0003] However, a scraper cannot be used to clean the surface of a liquid crystal panel with an ITO (Indium Tin Oxide Transparent Conductive Film) coating, otherwise scratches may occur on the ITO coating. The traditional abrasive belt used to clean the ITO coating on the surface of the LCD screen mainly contains alumina abrasive particles, which may cause scratches on the ITO coating and affect the yield of the LCD screen. [0004] Therefore, it is necessary to develop a new abrasive and abrasive article, which can be used to clean the surface...
