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 baking paint of a silver gray low-light writing board and color paste used thereby, which are invented to thoroughly solve the problem that the existing teaching blackboards of China's schools are serious in pollution of writing dust. The baking paint consists of resin, pigment, assistant, solvent and the like. The paint is coated on the existing steel blackboard, so that a blackboard is tough in coatings, strong in adhesion and non-glare. With a liquid environment-friendly writing pen matched for use, the blackboard has the advantages of writing well, easy rubbing, smooth writing, no dust pollution and the like, and the service life of the blackboard is long. Due to the soft color of the blackboard, the visual and metal states of students can be kept good, and the vision of the students is not damaged due to long use.

Description

technical field [0001] The invention relates to a color paste for silver-gray low-light writing board baking paint and a preparation method of silver-gray low-light writing board 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 affect...
