Problems solved by technology

[0003] (1) The use of whiteboards and beige boards in classrooms for teaching and writing does not meet the color requirements of the industry standard for blackboard safety and hygiene requirements (WS99-1998) promulgated by the Ministry of Health. Long-term use will affect students' vision
[0004] (2) The chalk writing used in the teaching process produces a lot of dust, which seriously affects the physical and mental health of teachers and students
[0005] (3) Some schools use white boards and beige boards. Such writing boards have high gloss, which affects students' viewing and teaching effect
[0006] (4) There are still a few schools that use film (green, yellow, etc.), which has poor adhesion, unevenness, unsightly appearance, short service life, and poor writing effect, which affects teaching

Abstract

The invention discloses a manufacturing method of a silver gray matt projection / writing board and a manufacturing method of a baking coating thereof. By adopting the product, the teaching writing needs of the traditional board writing can be satisfied, and the needs of interactive teaching via the modern information technology multimedia projection can also be satisfied. When the product is used together with easy-to-wipe teaching writing ink, the serious problem of dust pollution caused by use of chalks in teaching in the majority of schools in China can be solved completely, and the healthyschool construction in China can be promoted. The baking coating comprises resin, pigments, additives, solvents and the like. The coating is coated on a galvanized steel plate and baked at high temperature of 240-260DEG C for formation. Therefore, the product has a tough coating, good wear resistance, good chemical resistance, strong adhesion and good matt effects. When the product is used together with the easy-to-wipe teaching writing ink, the advantages of smooth writing, easy wiping, no dust pollution and long service life can be realized. The color of the product is soft, so that students can maintain good visual and mental state. During the long-term use, the product is conducive to the health of teachers and students.

Description

technical field [0001] The invention relates to a method for making a silver-gray matt projection writing board and a method for making its baking paint. Background technique [0002] At present, the common problems and disadvantages of the teaching blackboards used in the majority of schools in our country can be roughly divided into the following categories: [0003] (1) The use of whiteboards and beige boards in classrooms for teaching and writing does not meet the color requirements of the industry standard for blackboard safety and hygiene requirements (WS99-1998) promulgated by the Ministry of Health. Long-term use will affect students' vision. [0004] (2) the chalk writing that adopts in the teaching process produces a large amount of dust, has a strong impact on the physical and mental health of teachers and students. [0005] (3) Some schools use white boards and beige boards. Such writing boards have high gloss, which affects students' viewing and affects teachin...
