Embodiment 1

[0025] 1. Pretreatment

[0026] First, the brown corundum abrasive is subjected to alkali treatment with a NaOH solution with a concentration of about 6% under heating conditions. The temperature of the alkali treatment is controlled at about 70°C and the time is about 20 minutes. After the alkali treatment is completed, it is washed with water.

[0027] Next, heat treatment is carried out on the brown corundum abrasive after the above alkali treatment, and the temperature of the heat treatment is controlled to be about 1000° C. and the time is about 3 hours to obtain a pretreated abrasive.

[0028] 2. Dipping

[0029] Dissolve polyaluminum iron silicate and water-soluble titanate 200S (purchased from Yizheng Tianyang Chemical Factory) in water to prepare an impregnation solution; wherein, the mass content of polyaluminum iron silicate in the impregnation solution is about 0.2%, and the impregnation The mass content of the water-soluble titanate in the solution is about 0.1%....

Embodiment 2

[0034] 1. Pretreatment

[0035] First, the brown corundum abrasive is subjected to alkali treatment with a NaOH solution with a concentration of about 8% under heating conditions. The temperature of the alkali treatment is controlled at about 60°C and the time is about 30 minutes. After the alkali treatment is completed, it is washed with water.

[0036] Next, heat treatment is carried out on the brown corundum abrasive after the alkali treatment, and the temperature of the heat treatment is controlled to be about 1100° C. and the time is about 2.5 hours to obtain a pretreated abrasive.

[0037] 2. Dipping

[0038] Dissolve polyaluminum iron silicate and water-soluble titanate 200S (purchased from Yizheng Tianyang Chemical Factory) in water to prepare an impregnation solution; wherein, the mass content of polyaluminum iron silicate in the impregnation solution is about 0.1%, and the impregnation The mass content of the water-soluble titanate in the solution is about 0.15%.

Embodiment 3

[0043] 1. Pretreatment

[0044] First, the brown corundum abrasive is subjected to alkali treatment with a NaOH solution with a concentration of about 4% under heating conditions. The temperature of the alkali treatment is controlled at about 80°C and the time is about 40 minutes. After the alkali treatment is completed, it is washed with water.

[0045] Next, heat treatment is carried out on the brown corundum abrasive after the alkali treatment, and the temperature of the heat treatment is controlled to be about 1200° C., and the time is about 4.5 hours to obtain a pretreated abrasive.

[0046] 2. Dipping

[0047] Dissolve polyaluminum iron silicate and water-soluble titanate 200S (purchased from Yizheng Tianyang Chemical Factory) in water to prepare an impregnation solution; wherein, the mass content of polyaluminum iron silicate in the impregnation solution is about 0.3%, and the impregnation The mass content of the water-soluble titanate in the solution is about 0.1%.

Abstract

The invention provides a film platingplated grinding material and a preparation method thereof. The preparation method of the film platingplated grinding material comprises the following steps of performing pretreatment on the grinding material to obtain a pretreated grinding material; using a soaking solution containing ferric salt for soaking the pretreated grinding material; drying and roasting the soaked pretreated grinding material to obtain the film platingplated grinding material. The prepared film platingplated grinding material has the advantages of high intensity, strong combinationcapability with combination agentsto binding agents and excellent grinding effects.

Description

technical field [0001] The invention relates to an abrasive, in particular to a coated abrasive and a preparation method thereof. Background technique [0002] Brown corundum is a brown artificial corundum made of high-quality abrasive grade bauxite, which is refined in an electric arc furnace at a temperature above 2250 °C in the presence of carbon materials and iron filings. The main chemical composition is Al 2 o 3 , the content is about 95-97%, and it also contains a small amount of Fe, Si, Ti and other elements. Brown corundum is widely used in the manufacture of grinding wheels, grinding blocks, abrasive belts, etc. due to its advantages of good self-sharpening, strong grinding force, and low price. [0003] Brown corundum abrasive is made by grinding brown corundum. During the process of frit cooling and crushing, due to the influence of cooling speed and mechanical force, there are certain internal stress and micro-cracks in the abrasive. It will affect the streng...
