Waterproof emery cloth for grinding of car industry and manufacturing method thereof

Abstract

The invention discloses a waterproof emery cloth for grinding of the car industry. The waterproof emery cloth comprises a base abrasive cloth, a base material reinforcing layer, abrasive particles and an adhesive, wherein the surface of the base abrasive cloth is divided into a plurality of areas; the abrasive particles attached in the same area have the different size, and the abrasive particles attached in different areas are different in size; the size of the abrasive particles attached to each area of the base material reinforcing layer gradually increases from the center of the base abrasive cloth to the side edge of a base material; the abrasive particles are compound abrasive particles and prepared by compounding nanometer cerium dioxide particles and silicon dioxide particles; the adhesive comprises a component A and a component B. The invention further designs a manufacturing method of the waterproof emery cloth for grinding of the car industry. The method comprises the following processes: coating the adhesive; pre-curing; arranging sand; post-curing; flexing with water; cutting with laser; performing anti-deformation treatment for the base material; storing. The manufacturing method is simple and easy to carry out, and low in manufacturing cost; the manufactured waterproof emery cloth for grinding is resistant to ageing, resistant to fatigue, resistant to high temperature, resistant to abrasion, and long in service life.

Description

technical field [0001] The invention relates to an abrasive cloth and a manufacturing method thereof, in particular to a water-resistant abrasive cloth for automotive industry grinding and a manufacturing method thereof, belonging to the technical field of abrasive tools. Background technique [0002] Grinding is one of the main methods of finishing in machining. In the automobile manufacturing industry, grinding accounts for 25% of the entire machining. With the development of blank manufacturing technology, the precision of the blank has been greatly improved, and the blank can be directly ground, so that the application of grinding in the automobile manufacturing industry is more extensive. The abrasives used in the traditional automobile industry are steel paper sand discs. Steel paper sand discs are also called steel paper grinding discs, high-speed grinding discs, and grinding discs. They are made of steel paper as the base material and synthetic resin as the binder. ...

Problems solved by technology

It has high tensile strength and extremely strong wear resistance. It can be installed on electric or pneumatic angle grinders to derust, deburr, paint and weld welds on various surfaces of metal and non-metal materials. It is an ideal tool for grinding, smoothing and polishing in manufacturing and mechanical processing. It is widely used in automobile, machinery, shipbuilding, metallurgy, instrumentation, bridge and construction industries, but the existing grinding discs have disadvantages such as poor wear resistance and short service life. more and more obvious
