Production process of polyester water-resistant emery cloth with high adhesive power

Abstract

The invention discloses a production process of high-adhesion polyester water-resistant abrasive cloth, which adopts water-resistant sandpaper as a cloth base for production; after scraping the sand-planted surface of the cloth base, corona treatment is performed on the sand-planted surface of the cloth base; Squeegee coating material, base rubber material and re-adhesive compound are all added with heat-dissipating materials and heat-conducting materials; the abrasive used for sand planting is diamond abrasive grain; the diamond abrasive grain layer (3) is coated with a re-adhesive layer (4) , the substrate (1) is a non-woven material; by mass percentage, the components of the primer layer (2) and the contents of each component are: 50% to 75% of epoxy modified phenolic resin, 15% to 15% of softening agent 35%, thickening lubricant 2%~5%, tackifier 8%~15%, the sum of the mass percentages of the above-mentioned components is 100%; by mass percentage, the components and The content of each component is: 60%-75% of water-based epoxy resin, 2%-10% of internal mixed antistatic agent, 15%-35% of auxiliary materials, and the sum of the mass percentages of the above-mentioned components is 100%.

Description

technical field [0001] The invention belongs to the technical field of abrasive cloth manufacture, in particular to a production process of high-adhesion polyester water-resistant abrasive cloth. Background technique [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 ...

[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;
