Problems solved by technology

However, each step of the existing backing treatment process needs to be treated with a solution, and therefore needs to be heated and dried in an oven, which makes the treatment process complicated and consumes a lot of energy, which not only increases costs but also wastes time
In addition, the solutions used in the backing process usually involve a large amount of organic solvents, which are highly toxic and pollute and cause great harm to the environment, and because most of the organic solutions are volatilized after drying, further increasing the solution Loss and Energy Consumption

Embodiment 1

[0034] The PRIMACORTM 3330 copolymer (Ethylene / acrylic acid copolymer of 2-acrylic acid and ethylene, referred to as EAA) produced by Dow Chemical (Shanghai) Co., Ltd. is used as the coating material, and the gram produced by Shandong Taipeng Nonwoven Co., Ltd. is used. The PET spunbond with a weight of 80 to 150 grams per square meter is used as the back base (hereinafter referred to as PET non-woven fabric). The EAA particles are put into the feeding chamber 22 of the extrusion device 20, the temperature of the feeding chamber 22 is set to 160 to 170 degrees to heat the EAA particles into a molten state, and the distance between the extrusion rollers 24 is adjusted to obtain a thickness of 20 microns, 50 micron and 70 micron EAA membranes. Thereafter, EAA films of various thicknesses were respectively attached to the upper surface of the PET nonwoven fabric by using the attaching device 30 . Next, the temperature of the heat-pressing device 40 was set to 145 degrees Celsius...

Embodiment 2

[0037] The 3M615 adhesive film produced by 3M Company is used as the coating material, and the pure cotton cloth base with a grammage of 150 to 200 g / m2 and a radial tensile strength of 700 to 900 N / 5 cm is used as the backing. Use the sticking device 30 to stick the 3M615 adhesive film to the upper surface of the pure cotton cloth base respectively. Next, set the temperature of the hot pressing device 40 to 135 degrees Celsius, the pressure to 10-20 psi and the hot pressing time to 10 seconds. The 3M615 adhesive film attached to the upper surface of the pure cotton cloth base is heated and melted in the hot pressing device 40 so as to fully contact with the pure cotton cloth base and pressed into the pure cotton cloth base from the upper surface under pressure. After the hot pressing lasts for a sufficient time, the 3M615 adhesive film is pressed from the upper surface of the pure cotton cloth base to the lower surface thereof, that is, the 3M615 adhesive film is completely p...

[0039] The 3M690 adhesive film produced by 3M Company is used as the coating material, and the pure cotton cloth base with a grammage of 150 to 200 g / m2 and a radial tensile strength of 700 to 900 N / 5 cm is used as the backing. Use the sticking device 30 to stick the 3M690 adhesive film to the upper surface of the pure cotton cloth base respectively. Next, the temperature of the heat-pressing device 40 was set to 175 degrees Celsius and the heat-pressing time was set to 10 seconds. The 3M690 adhesive film attached to the upper surface of the pure cotton cloth base is heated and melted in the hot pressing device 40 so as to fully contact with the pure cotton cloth base and pressed into the pure cotton cloth base from the upper surface under pressure. After the hot pressing lasts for a sufficient time, the 3M690 adhesive film is pressed from the upper surface of the pure cotton cloth base to the lower surface thereof, that is, the 3M690 adhesive film is completely pressed into t...

Abstract

The present disclosure relates to a method and system for treating an grinding tool backing. The method comprises the steps of providing a backing, wherein the backing is provided with a first surfaceand a second surface opposite to the first surface; providing a coating material, wherein the coating material is in a solid state at room temperature; and hot pressing the coating material from thefirst surface to the backing to form a coating layer composed of the coating material on the first surface of the backing. By mean of the method and system for treating the grinding tool backing, theprocessing process of the grinding tool backing can be simplified, and the processing energy consumption and the processing cost of the grinding tool backing can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of abrasive tool processing, and more particularly, to a processing method and system for abrasive tool backing. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Coated abrasives are tools that can be cleaned, ground, and polished, and can be widely used in the field of household cleaning and various mechanical processing fields such as metal, glass, stone, plastic, and wood. Generally, coated abrasives are made by bonding abrasive grains to a flexible backing material with an adhesive, wherein the flexible backing material is usually made of cloth, paper, non-woven fabric and the like. Due to the low bonding strength of these common backing materials and adhesives and a large number of voids in the backing materials, which may infiltrate the adhesive and affect the perform...
