Embodiment 1

[0028] A method for preparing a fiber composite material for grinding and polishing, characterized in that it comprises the following steps:

[0029] 1) Processing and treatment of fiber materials: cut the wool felt with a thickness of 10mm into a circle with a diameter of 250mm, and punch it into a honeycomb shape with a honeycomb aperture of 4mm and a hole distance of 8mm, and then place it in a polishing agent solution Soak in water for 3-4 hours, then remove and dry for later use.

[0030] The polishing agent solution is prepared from water, ammonium dichromate and oxalic acid, and the ammonium dichromate is baked at 150°C for 1 hour before the preparation, wherein the weight ratio of water to ammonium dichromate and oxalic acid is 1000:20 : 3, so that it can be fully dissolved at room temperature.

[0031] After soaking for 3-4 hours, the aqueous solution rich in ammonium dichromate and oxalic acid fills all the gaps in the wool felt. On the one hand, the solution reacts...

Embodiment 2

[0037] A method for preparing a fiber composite material for grinding and polishing, characterized in that it comprises the following steps:

[0038] 1) Processing and treatment of fiber materials: Cut the wool felt with a thickness of about 10mm into a circle (Φ=250mm) and punch it into a honeycomb shape. The honeycomb aperture is about 5mm and the hole distance is 9mm. Soak in water for 3-4 hours, then remove and dry for later use.

[0039] Step 1) The leaching solution is prepared from water, ammonium dichromate and oxalic acid, and the ammonium dichromate is baked at 155°C for 1.5 hours before preparation, wherein the weight ratio of water to ammonium dichromate and oxalic acid is 1000:25:4, so that it can be fully dissolved at room temperature.

[0040] After soaking for 3-4 hours, the aqueous solution rich in ammonium dichromate and oxalic acid fills all the gaps in the wool felt. On the one hand, the solution reacts with impurities in the wool felt to reduce the roughn...

Embodiment 3

[0046] A method for preparing a fiber composite material for grinding and polishing, characterized in that it comprises the following steps:

[0047] 1) Processing and treatment of fiber materials: cut the wool felt with a thickness of about 10mm into a circle (Φ=250mm) and punch it into a honeycomb shape with a honeycomb aperture of 6mm and a distance of 10mm, and then place it in the soaking solution Soak for 3-4 hours, then remove and dry for later use.

[0048] Step 1) The leaching solution is prepared from water, ammonium dichromate and oxalic acid, and the ammonium dichromate is baked at 160°C for 3 hours before preparation, and the weight ratio of water to ammonium dichromate and oxalic acid is correspondingly 1000:30:5, so that it can be fully dissolved at room temperature.

[0049] After soaking for 3-4 hours, the aqueous solution rich in ammonium dichromate and oxalic acid fills all the gaps in the wool felt. On the one hand, the solution reacts with impurities in t...

Abstract

The invention discloses a grinding and polishing synthetic fiber material preparation method. The fiber synthetic material preparation method includes and is characterized by including preliminarily processing fiber materials, penetrating thin glue, pressing a composite material uniformly mixed with polishing agent, strengthening plasticizer and adhesive, and integrally drying at constant temperature to enable the fiber materials, the polishing agent, the strengthening plasticizer and the like to be firmly solidified to form a uniform and elastic integral body. The synthetic materials have the advantages that the synthetic materials are quick polished, low in consumables, durable, wear-resisting, low in production cost, simple in technique, easy to realize industrial lives, and the like.

Description

technical field [0001] The invention relates to a preparation method of a fiber composite material for grinding and polishing. The obtained grinding and polishing fiber material has the advantages of fast glazing speed, less consumables, good friction resistance and the like, and can be widely used in industrial fields. Background technique [0002] Rock mineral aggregates are extremely complex and changeable heterogeneous substances formed by natural crustal changes. In geological prospecting, geotechnical engineering and environmental protection, it is often necessary to grind mineral rock aggregates into a certain thickness of light Slices, thin slices or polished surfaces for genetic analysis, composition research and structural research. The traditional polishing process is to attach a layer of navy, canvas or wool felt to a metal disc to form a polishing disc, and then make the polishing disc rotate at a high speed and continuously add polishing materials, so that the ...
