Problems solved by technology

[0003] The traditional blackboard chalk teaching writing method has serious dust pollution, and the emergence of whiteboards and whiteboard markers has completely solved this problem. However, the service life of whiteboards on the market is very short. Although they can be erased by themselves, they will leave traces. The whiteboard will lose its function after a long time, so it is necessary to develop a new type of durable coating, so that it is not easy to leave marks after the whiteboard pen is wiped off, and the coating will not be damaged when cleaning with a solvent after spraying paint or oil pen.

Abstract

The invention discloses a doodling prevention powder coating, which comprises the following components in part by weight: 150 to 250 parts of acrylic resin, 30 to 40 parts of acrylic acid curing agent, 20 to 100 parts of titanium dioxide, and 1 to 20 parts of auxiliary agent. The invention also discloses a method for preparing the doodling prevention powder coating. The powder coating has the characteristics of simple formula, convenient coating and curing, excellent chemical resistance, capability of being erased, convenience for repeated doodling and the like. By changing species and dosage of each component, coatings with different colors and different capacities of washing resistance and doodling prevention can be obtained. The product of the invention can be suitable for indoor and outdoor occasions, and the application range of the product comprises the coating of white boards and public facilities, such as road indication boards, bus stops, newspaper boxes, common supplies and the like.

Description

technical field [0001] The invention relates to a powder coating, in particular to an anti-graffiti powder coating, and simultaneously the invention also relates to a preparation method of the powder coating. Background technique [0002] Graffiti, a so-called form of artistic expression is often considered immoral. States, local councils, property owners etc spend millions of dollars every year to remove graffiti. Evidence shows that the most effective way to prevent the spread of graffiti is to remove it quickly. [0003] The traditional blackboard chalk teaching writing method has serious dust pollution, and the emergence of whiteboards and whiteboard markers has completely solved this problem. However, the service life of whiteboards on the market is very short. Although they can be erased by themselves, they will leave traces. The whiteboard will lose its function after a long time, so it is necessary to develop a new type of durable coating, so that it is not easy to...
