Abstract

The invention discloses a process for treating wear-resistant materials of liquid wear-resistant paper, which belongs to the technical field of wear-resistant materials. It solves the problem that the wear resistance of the wear-resistant material treated by the existing treatment process is unstable, and the production process is easy to produce white spots. It includes the following steps: (1) The configuration of the treatment liquid: add ethanol to the silane coupling agent and stir evenly After obtaining the silane coupling agent alcohol solution, continue to add the melamine formaldehyde prepolymer of solid content 10-15% in this solution, after stirring for 20-40 minutes, adjust the pH of the solution to neutrality with oxalic acid solution; (2) treatment solution Wear-resistant material: Put the corundum powder into the mixing tank, spray the treatment liquid into the corundum powder while stirring, continue stirring for 15‑30 minutes after the treatment liquid is sprayed, and then dry the corundum at no higher than 100 °C The moisture content in the powder is between 3% and 5%. The invention can be used to treat wear-resistant material of liquid wear-resistant paper.

Description

technical field [0001] The invention relates to a treatment process for wear-resistant materials used in liquid wear-resistant paper, and belongs to the technical field of wear-resistant materials. Background technique [0002] The wear-resistant paper is impregnated with melamine and additives, and the board is hot-pressed by the steel plate of the hot press to become a veneer board, which is widely used in the veneer of cabinets, wardrobes, and Bell laminate flooring. [0003] Due to the poor compatibility between inorganic corundum powder and melamine resin, wear-resistant materials generally need to be treated before use. The existing technology is to directly spray silane coupling agent on the filler and stir in a mixer for 10-30 minutes. Dry after filling treatment. In this method, due to the instability of the coupling agent during the treatment process, it is easy to cause white spots on the liquid wear-resistant paper, and the wear resistance is unstable, which eve...
