Abstract
The invention discloses an environmental-friendly coating for blackboards. The coating comprises following components in parts by weight: 45 to 50 parts of organic silicon modified epoxy resin, 9 to 11 parts of stuffing materials, 2 to 6 parts of methyl methacrylate, 5 to 9 parts of methyl triethoxysilane, 10 parts of kaolin, 20 parts of gypsum, 20 parts of cement, 5 to 10 parts of methyl cellulose, and 1 part of sodium dodecanesulphonate. Blackboards made of the environmental-friendly coating have the advantages of convenient preparation, sanitation and hygiene in writing, good writing quality, low price, good anti-friction property, no-deforming, no-cracking, aging resistance, and long service life.
Description
Technical field
The present invention relates to a kind of environment-friendly type blackboard for education material.
Background technology
Must use blackboard when teaching, existing blackboard has experienced several stages such as cement blackboard, wooden blackboard, obscure glass blackboard, metallic blackboard substantially.Wherein, cement blackboard and wooden blackboard belong to first-generation product, and its shortcoming is that dust is many, reflective, physically and mentally healthy unfavorable to teachers and students, and in writing process, easily skid, the cement blackboard is at the overcast and rainy globule that also easily condenses, these two kinds of blackboards all will be maintained every year, the obscure glass black print belongs to s-generation blackboard, and its shortcoming is that dust is many, is difficult for cleaning, break easily, metallic blackboard belongs to third generation blackboard, and its shortcoming is easily to get rusty, and is expensive.
Summary of the invention
Technical problem to be solved by this invention is: a kind of environment-friendly type blackboard for education material is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of environmental protection type blackboard coating, composition by following parts by weight forms: 45-50 part modifying epoxy resin by organosilicon, 9-11 part filler, methyl methacrylate 2-6 part, Union carbide A-162 5-9 part, 10 parts of kaolin, 20 parts of gypsum, 20 parts of cement, 5-10 part methylcellulose gum, 1 part of sodium laurylsulfonate.
Blackboard of the present invention is easy to make, sanitation and hygiene when writing, writing quality are good, low price, wear resistance is good, indeformable, do not ftracture, be difficult for aging, long service life.
