Environment-friendly gloss paint suitable for automatic pencil coloring machine and preparation method of environment-friendly gloss paint

Abstract

The invention relates to the technical field of pencil paint, and discloses environment-friendly gloss paint suitable for an automatic pencil coloring machine and a preparation method of the environment-friendly gloss paint. Comprising the following components in parts by mass: 80 to 90 parts of water-based resin, 0.2 to 1 part of a defoaming agent, 0.1 to 0.5 part of a dispersing agent, 3.5 to 7 parts of a coalescing agent, 2 to 7 parts of extinction powder, 0.1 to 0.2 part of a sterilizing agent, 0.1 to 0.2 part of an antibacterial agent, 1 to 4 parts of a thickening agent, 0.05 to 0.1 part of a neutralizing agent, 0.5 to 3 parts of a hand feeling agent and 0.1 to 0.5 part of a flatting agent. The water-based resin forms an elastic and glossy component of the varnish and can reduce the volatility of the coalescing agent, the defoaming agent prevents a finished product from generating pits, the dispersing agent contributes to uniform mixing of all the components, the matting powder realizes a matte effect, the thickening agent adjusts the viscosity of the varnish in a varnish cylinder, and the flatting agent promotes the fluidity of the varnish and contributes to smoothness of the coating process; the gloss paint reaches the paint flowability standard of an automatic painting machine, the automatically painted pencils have uniform and full matte texture and certain dustproof performance, the volatility of the paint is small, and ambient air pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of pencil paint, in particular to an environment-friendly gloss paint suitable for an automatic pencil coloring machine and a preparation method thereof. Background technique [0002] The automation of pencil painting is an inevitable trend in the production of modern pencil industry. The most commonly used automatic painting and coloring method is to inject pencils into the paint tank, then shoot and dry, and the pencils are painted in the paint tank. Process control is the key to the quality control of pencil painting. The pencil is quickly painted through the paint tank. There is an inner rubber ring in the paint tank for the pencil to pass through. It is used to control the amount of paint. The viscosity and shear force of the paint directly affect the pencil. The adhesion time with the paint will then affect the thickness and quality of the pencil paint. Therefore, it is necessary to design a paint that...
