Abstract

The invention belongs to the field of coated abrasive tools, and relates to a process for producing super-soft sand cloth, comprising the steps of base cloth treatment, base glue application, sand planting, composite glue application and after treatment. The process for producing the super-soft sand cloth is characterized in that adhesives used for base cloth treatment comprises latex and resin, and comprises the following components in percentage by weight: 75-92 percent of latex, 5-20 percent of epoxide resin and 1-5 percent of thickening agent; and meanwhile, polyurethane is adopted for modifying main adhesives such as phenol-formaldehyde resin and the like, and the main adhesives comprises the following components in percentage by weight: 15-35 percent of polyurethane elastomer, 60-80 percent of phenol-formaldehyde resin, 2-5 percent of accelerator and 2-4 percent of curing agent. The sand cloth product produced by the process has good grinding and adhesion performances, remarkably improved plasticity and elasticity, and the characteristic of small bending radius, and can satisfy the grinding requirement of workpieces with complicated surfaces and slim slotted hole type special workpieces.

Description

technical field [0001] The invention belongs to the field of coated abrasives, and relates to a production process of abrasive cloth, in particular to a production process of supersoft abrasive cloth. Background technique [0002] Abrasives are a kind of grinding tools, which are generally used for grinding and polishing the surface of utensils. According to their uses, they can be divided into manual abrasives and machine abrasives. The objects to be polished can be metal, wood, stone, glass products, etc. The shapes of the products are diverse, so the abrasive products are required to have a wide range of practicability, and special grinding requirements will also be put forward for special products. Especially when the object to be ground is in the following two situations, whether it is a manual abrasive tool or a machine abrasive tool, it is usually difficult to meet the grinding requirements: one is that the surface of the workpiece to be ground is uneven or has many c...
