Problems solved by technology

Especially in terms of wear resistance and water resistance, the performance is poor
There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific performance is: (1) Water resistance. Low cutting efficiency
(2) The bonding strength of the alkyd resin used is low, the abrasive is easy to fall off during use, and the wear resistance is poor
(3) The adhesive used is brittle, and the emery cloth is easy to age, and cracks will appear after being placed for about two months, which will seriously affect the performance

Embodiment Construction

[0004] This specific embodiment adopts the following process steps: 1. Unwinding; 2. Dipping; 3. Coating; 4. Calendering and setting; 5. Winding; Gravity cork particle sand planting; 9. Pre-drying; 10. Coating glue and abrasive; 11. Main drying; 12. Winding; 13. Unwinding; 14. Coating glue; 15. Main drying; 16. Curing; 17 , soft song; 18, divided into volumes; 19, storage. In the present invention, the cork particles are crushed into abrasive shapes, and after treatment, the cork particles are coated on the substrate with an adhesive, and then the abrasive is mixed in the compound glue, which is coated in the gaps of the cork particles, thereby making A kind of elastic high-speed fine sanding cloth. The invention has the characteristics of water resistance, good grinding and polishing performance, and strong anti-clogging ability, and is particularly prominent in maintaining consistent surface finish, and is suitable for high-speed grinding that requires cooling water. The s...

Abstract

The invention relates to a precision-grinding cork emery cloth for grinding and polishing metals, in particular to a precision-grinding sanding cloth. The precision-grinding cork emery cloth is prepared by the following processing steps: 1, unwinding; 2, impregnation; 3, coating; 4, calendering and stereotyping; 5, winding; 6, unwinding and printing trademarks; 7, gluing primer; 8, planting emery under the vibration of gravity cork particles; 9, pre-drying; 10, coating glue and grinding; 11, main drying; 12, winding; 13, unwinding; 14, coating the glue; 15, main drying; 16, curing; 17, curving; 18, bundling; and 19, storing. The precision-grinding cork emery cloth has the characteristics of water proofing, good grinding and polishing performance, strong anti-blocking capacity and the like, is particularly prominent in maintaining consistent surface finish and the like, and is suitable for high speed grinding needing cooling water.

Description

Technical field: [0001] The invention relates to an emery cloth for metal grinding and polishing, in particular to a fine emery cloth. Background technique: [0002] At present, the consumption of high-grade grinding materials in China is wide and large, with an annual consumption of about 200 million square meters, and the grade of domestic coated abrasive products is relatively low. Especially in terms of wear resistance and water resistance, the performance is poor. There is a lack of suitable high-speed grinding products, especially in terms of water resistance. The water-resistant products used in China are still at the level of the 1960s. The specific performance is: (1) Water resistance. Cutting efficiency is low. (2) The bonding strength of the alkyd resin used is low, the abrasives are easy to fall off during use, and the wear resistance is poor. (3) The adhesive used is brittle, and the emery cloth is easy to age, and cracks will appear after being placed for ab...
