Description

technical field [0001] The invention relates to a water-based primer for coating wooden pencils, which is used for coating and priming wooden pencils. technical background [0002] Pencil is the main writing tool in the cultural life of modern people. The most traditional wooden pencil is still the main tool in the fields of sketching, drawing, examination, and make-up due to its writing characteristics, and has an irreplaceable position. In order to protect and look good on the wooden pencil, it must be painted, and to achieve the ideal painting effect, a primer must be applied first. That is, use a paint machine to apply a white primer on the surface of the wooden pole, and then apply a colored topcoat. The purpose of coating the white primer is to cover the texture of the wooden pole surface and the original color of the wood, improve the smoothness of the surface, and facilitate the smoothness, gloss and color of the colored topcoat. [0003] At present, the coating pr...
