Problems solved by technology

However, although this patent realizes the environmental protection of the use and preparation process to a certain extent, it does not solve the properties such as fast surface drying and suitable viscosity required by the pull-in coating process, and it cannot achieve the purpose of uniform color. The hardness of the paint film is not high. Therefore, those skilled in the art urgently need to find a kind of wood pencil paint that can be applied to the plug-in coating process, and has the properties of safety and environmental protection, uniform color, and good hardness.

Abstract

The invention discloses environment-friendly waterborne pencil colored paint suitable for a wooden pencil as well as a preparation method and an application of the environment-friendly waterborne pencil colored paint. The environment-friendly waterborne pencil colored paint is prepared from raw materials as follows: waterborne polyurethane, a coalescing agent, color paste, filler and water, wherein the filler is prepared from 5%-25% by mass of calcium carbonate, 3%-20% by mass of kaolin and 3%-10% by mass of wax powder, and a feeding mass ratio of calcium carbonate, kaolin and the wax powder is (3-6):(1.2-2):1. The preparation method comprises the step that the raw materials are mixed uniformly, and the environment-friendly waterborne pencil colored paint is prepared. The invention furtherprovides the application of the colored paint to a painting pencil and the wooden pencil prepared from the colored paint by painting. The colored paint integrates properties of uniform color, short surface drying time, high hardness and the like on the premise of safety and environmental protection, and has good film-forming property.

Description

technical field [0001] The invention belongs to the field of stationery, and in particular relates to an environmental-friendly water-based pencil color paint suitable for wood pencils and a preparation method and application thereof. Background technique [0002] For the coating process on the pencil surface, there is a push-and-pull pencil coating, which allows the pencil to pass through the area where the pencil color paint is applied during the movement, so that the pencil color paint is coated on the outer surface of the pencil, forming a film, giving Different colors of pencils; and this push-and-pull process requires pencil paint to have excellent dry time, suitable viscosity, and good film-forming properties. If the dry time is too long, the film will be too slow, and the pencil paint will be Unevenness, poor hiding power, obvious color difference, insufficient or too high viscosity, it is difficult to form a surface film with excellent performance, and the hardness ...
