Problems solved by technology

It can be found that when the type, particle size or hardness of the rubber particles used is changed, or the size of the grinding stone is changed, conditions such as molding pressure and heat treatment temperature must be found and adjusted again. Therefore, the method of this disclosure may be It is not yet able to meet the needs of the current industry

Embodiment 1

[0047] The first mixing step: 100g of styrene-butadiene rubber (hereinafter referred to as SBR) is placed on the rollers of 6-inch double rollers (manufacturer: Jin Naihe Industrial Co., Ltd., model: ML1-2-1) and rolled After making the SBR circle around the roller, slowly add 750g of ceria (manufacturer: China Baotou Steel, white powder, particle size D50=0.9μm), and active agent (8g of zinc oxide and 2.5g of stearin acid), and then mix SBR, cerium oxide and active agent uniformly in a triangular bag to obtain a mixture, then roll the mixture into a sheet and cool it for later use, the mixing temperature is 50°C to 100°C, and the mixing time is about 10 minutes to 20 minutes.

[0048] The second mixing step: this sheet is placed on the roller of 6 inch twin-roller (manufacturer: Jin Naihe Industrial Co., Ltd., model: ML1-2-1), adjusts the roller distance of twin-roller so that this sheet can be in Form a circle around the double rollers, slowly add 50g of insoluble sulfur (m...

Abstract

The invention provides a piece of grinding stone, a grinding member including the grinding stone, and a manufacturing method of the grinding member. The grinding stone is formed by a grinding stone composition through mixing and hot compression and includes perduren and a plurality of grinding particles dispersed around the perduren, the sulphur content of the perduren in the range of 10-30 wt%. The manufacturing method of the grinding member includes a first mixing step, a second mixing step, and a hot compression forming step. The manufacturing method, by means of controlling the sulfuration crosslinking of the perduren, enables the grinding particles of the grinding stone to be properly come off, when the formed grinding member grinds an article to be grinded which is less in bending strength caused by cutting, and therefore, the polishing strengthening of the article to be grinded is facilitated and the bending strength of the article to be grinded can be recovered.

Description

technical field [0001] The invention relates to a grinding stone, a grinding wheel containing it and a manufacturing method thereof, in particular to a grinding stone containing vulcanized rubber, a grinding piece containing the grinding stone, and a manufacturing method of the grinding piece. Background technique [0002] After the large-size panel process is completed, it will be cut to obtain a small-size panel of a predetermined size. However, when the glass panel is cut, tiny cracks will be formed on the glass panel, and stress concentration will occur at the cracks, so that the bending strength of the glass panel will decrease. At present, there are two main methods for improving the bending strength of glass panels: physical strengthening and chemical strengthening. Chemical strengthening is to immerse the cut glass panel in a chemical corrosion solution. The disadvantage is that the corrosion solution may damage the glass panel circuit and may endanger the safety of...
