Production process of emery cloth

Abstract

The invention discloses a production process of emery cloth. The production process of the emery cloth includes the working procedures of base cloth processing, base glue feeding, abrasive grain dispensing, repeating glue feeding and finishing. An adhesive used for base cloth processing is formed by latex and resin, and is prepared according to the following steps that firstly, water-based epoxy resin is added into the latex, and uniform stirring is performed under the temperature of 25-40 DEG C; and secondly, a proper amount of thickening agent is added into a glue solution obtained in the first step, stirring is performed for 25-45 min, various technical indicators are detected, and filtering is performed for use after detection is qualified. The grinding gravel is composed of, by mass percentage, 60%-70% of brazing pre-alloyed powder and 30%-40% of a diamond/cubic boron nitride mixture; and according to a preparation method of the grinding gravel, after material mixing of the brazing pre-alloyed powder, the brazing pre-alloyed powder is mixed with diamond/cubic boron nitride, cold pressing is performed to form thin sheets, then the cold-pressed thin sheets are contained in a high-temperature-resistant ceramic combustion boat to be fed into a vacuum brazing heating device to be heated and sintered, and after heat preservation is performed for 30 min, natural cooling with the furnace is performed.

Description

Technical field [0001] The invention belongs to the technical field of abrasive cloth manufacturing, in particular to a production process of abrasive cloth. Background technique [0002] There are many types of polishing grinders currently used in the market, most of which are sheet-shaped sandpaper, which is mainly composed of substrate, viscose and abrasive. The substance that connects two kinds of solid substances of the same or different types together is called an adhesive. Adhesive, adhesive or directly called glue. Adhesive is actually a raw additive. When it is in a raw state, it has no viscosity. Only when it is heated to a certain temperature on the paste line, it becomes a strong Adhesive, adhesive is an indispensable material in production and life. [0003] At present, it has been applied in various fields, such as: transportation, aerospace industry, construction, furniture, medical equipment, etc.; an adhesive for grid grinding emery cloth, which mixes the abrasive...

Problems solved by technology

[0003] At present, it has been applied to various fields, such as: transportation, aerospace industry, construction, furniture, medical equipment, etc.; an adhesive for grid grinding emery cloth, which mixes the abrasive with the adhesive and then bonds it to the surface of the emery cloth to hold the abrasive. It is an important factor affecting the performance of abrasive cloth abrasives. The synthesis and performance of adhesives directly affect the performance of abrasive cloth abrasives. With the continuous improvement of production levels, the demand for abrasive cloth is also more extensive, and people need higher levels. High-quality abrasive cloth to meet the needs of actual production, especially suitable for grinding metal, wood, and electronic industries; but due to the poor anti-clogging effect of conventional sandpaper and abrasive cloth products, the grinding life is short
