Problems solved by technology

[0002] At present, there are many kinds of polishing abrasives used in the market, most of which are abrasive paper, which is commonly known as sand skin, which is a kind of material used to grind the surface of metal, wood, etc. to make it smooth and clean. It is made of grinding sand, and the base material is mostly made of paper material or single-layer cloth or film. The paper material is not soft enough when used, the paper base is easy to be brittle and damaged, and it is easy to rot when exposed to water. It is easy to scratch and polish when using equipment; while using a single layer of cloth or film as a base material is easy to wear, especially for equipment with a rough surface, the loss is greater, and it is very undurable. Generally, the item is roughly ground before fine grinding , Each time you polish an item, you need to use different types of sandpaper for rough grinding and fine grinding, which is troublesome to replace, and you need to replace two kinds of sandpaper, which increases the cost;

Embodiment 1

[0023] This embodiment provides a production process for a soft emery cloth, including base cloth treatment, primer application, sand planting, gluing, and post-processing procedures. The adhesive used for base cloth treatment is composed of latex and resin. The preparation is as follows: (1) Add water-based epoxy resin to the latex, and stir evenly at 31°C; (2) Add an appropriate amount of thickener to the glue obtained in step (1), stir for 33 minutes, and test various technical indicators , filtered and used after passing the test. The abrasive particles used for sand planting are composite abrasive particles. The specific preparation method of the composite abrasive particles is as follows:

Abstract

The invention discloses a production process of soft abrasive cloth. The production process of the soft abrasive cloth comprises the procedures of base cloth treatment, primer coating, abrasive grain dispensing, composite glue coating and finishing. An adhesive adopted during base cloth treatment is composed of latexes and resin, and is prepared through the following steps that (1) the water-borne epoxy resin is added to the latexes, and the mixture is stirred evenly at the temperature of 27-35 DEG C; and (2) a proper quantity of thickening agent is added to the adhesive solution obtained in the step (1), the new mixture is stirred for 25-45 minutes, technical indexes are detected, and the mixture is filtered for use after all the indexes pass the detection. Abrasive particles adopted in abrasive grain dispensing are composite abrasive particles and prepared specifically through the following steps of (1) preparation of mono-dispersed silicon dioxide particles and (2) preparation of the composite abrasive particles.
