Formulation and preparation method of polishing abrasive tools prepared by glass fiber leftover material

Abstract

The present invention discloses one kind of polishing tool of glass fiber leftover and its material recipe and making process. The recipe consists of glass fiber 20-50 wt%, abrasive 20-50 wt%, and phenolic resin 10-30 wt%. The making process includes the following steps: screening glass fiber leftover to eliminate impurity, mixing abrasive and partial phenolic resin, mixing the mixed abrasive and partial phenolic resin with the rest phenolic resin mechanically to form agglomerate, weighing and pressing to form inside some mold, cooling and demolding, cutting and trimming. The polishing tool of waste glass fiber may be used in polishing field with oil stain and water stain and may result in unforeseen effect.

Description

technical field

[0001] The invention relates to a formula of an abrasive tool and a manufacturing method thereof, in particular to a formula of a polishing abrasive tool made of glass fiber scraps and a manufacturing method thereof. The obtained solid block can be directly used as an abrasive tool product, It can also be made into a square, round or special shape and pasted on a mesh cover such as fiberglass to become a polishing abrasive for use in various tools. Background technique

[0002] During the production process of glass fiber and its products, some leftovers will be produced to varying degrees. The main component of these leftovers is glass fiber, which cannot be degraded. Some of them also contain different types of resins, which will cause spontaneous combustion after long-term storage. Since they cannot be fully utilized, these leftover materials can only be treated as industrial waste and become a non-degradable environmental pollutant. Based on the 600,000 ...
