Abstract

The invention relates to the technical field of grinding consumables, in particular to a composition for heavy abrasive paper shaping and a preparation method of the composition. The composition for heavy abrasive paper shaping comprises water, polyacrylate, polyvinyl alcohol, a preservative, sodium benzoate, an ethylene-vinyl acetate copolymer and a penetrant, wherein polyacrylate is used as a setting agent, polyvinyl alcohol is used as a sealant, sodium benzoate is further used as a preservative, the ethylene-vinyl acetate copolymer is used as a dispersing agent, and the used raw material isodorless and meets the environmental protection requirement; and compared with traditional physical effects, according to the formula, the influence of environmental conditions on paper base shapingis reduced by changing the internal molecular structure of the paper base, the polyvinyl alcohol can effectively prevent the paper base from absorbing water or losing water in the storage process, andtherefore it can be guaranteed that the product cannot be curled or flanged in the long-term storage process. The preparation method has the characteristics of simple process, low production cost andsuitability for large-scale production.

Description

technical field [0001] The invention relates to the technical field of grinding consumables, in particular to a composition for shaping heavy sandpaper and a preparation method thereof. Background technique [0002] In the prior art, the traditional paper-based shaping method is simply formed by mechanically compulsive flexing and pulling. This method is purely through the action of external force, forcing the paper base to perform a physical reaction so as to play a shaping role. This method in the prior art has a certain effect in a short time after the paper base has been shaped, but when the product is placed for a long time or affected by the ambient temperature and humidity, the paper base will slowly absorb or lose water and thus Make the surface of the product uneven or deformed by the sandpaper belt such as lotus leaves. Contents of the invention [0003] One of the objectives of the present invention is to address the deficiencies in the prior art and provide a ...
