Description

Anti-scratch dust-free writing board
Technical field
The utility model belongs to board technical field, particularly relates to a kind of anti-scratch dust-free writing board.
Background technology
At present, adopt blackboard, chalk as educational aid in teaching, blackboard coats pitch-dark by plank or cement plate surface or is made up of the focussing glass of lining black matrix; At present, blackboard can only be the chalk-writing of primary raw material by lime, and dust is very large, after student and teacher suck, has a strong impact on healthy.A kind of board disclosed in the patent No. 201120429753.6, employs watercolor pencil and imparts knowledge to students, but also needs to carry out wiping, and watercolor pencil price is higher, is also unfavorable for environmental protection, improves use cost.Therefore, be necessary that design is a kind of and automatically the word that writer writes on board can be carried out auto-erasing, effectively improve writer's surrounding environment, and greatly reduce use cost, better meet the anti-scratch dust-free writing board of the needs of writer, become the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides a kind of anti-scratch dust-free writing board, this anti-scratch dust-free writing board is convenient to installation and removal, and easily clean, outward appearance is beautiful, fastness is good, automatically the word that writer writes on clipboard can be carried out auto-erasing, also reduce distortion, scratch and avoid surface oxidation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-scratch dust-free writing board, comprise the substrate with black upper surface, write pad pasting, upper side frame and lower frame, on the upper surface that described upper side frame and lower frame are installed on substrate respectively and lower surface, this upper side frame and lower frame side is in opposite directions respectively arranged with upper hopper chute, gliding groove, this upper hopper chute, top sheave is embedded with respectively in gliding groove, lower sheave, one litter one end is arranged on top sheave, this litter other end is arranged on lower sheave, the described pad pasting that writes is made up of polyester film and the micropore adhesive layer being coated on polyester film surface, micropore adhesive layer is positioned at polyester film and substrate surface in opposite directions, primary antibodie scraping coating is coated on the surface of described polyester film and micropore adhesive layer.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, the thickness of described micropore adhesive layer is 20 μm ~ 60 μm, and pore density is 1000 ~ 3000/cubic centimetre
2, in such scheme, the thickness of described polyester film is 75 μm ~ 200 μm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The anti-oxidant dust-free writing board of the utility model, its structure is simple, reasonable in design, production cost is low, be convenient to installation and removal, easily clean, outward appearance is beautiful, fastness is good, automatically the word that writer writes on clipboard can be carried out auto-erasing, effectively improve writer's surrounding environment, improve efficiency of erasing, and both greatly reduce use cost, also reduce pollution; Secondly, its anti-scratch coating is coated on the surface of described polyester film and micropore adhesive layer, greatly reduces distortion, scratch and avoids surface oxidation, improve wearability, and the more difficult scratch of general hard object or scrape is worn.
Accompanying drawing explanation
