Technical field
The utility model belongs to board technical field, particularly relates to one and exempts from wiping and to write film.
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, the wiping of exempting from better meeting the needs of writer is write film, becomes the direction that those skilled in the art make great efforts.
Summary of the invention
The utility model provides one to exempt from wiping and to write film, and this exempts from the wiping film that writes and effectively improves writer's surrounding environment, both also can put forward the sense of touch that the pad pasting that writes is write, also greatly improve viewing board angular field of view and definition.
For achieving the above object, the technical solution adopted in the utility model is: one is exempted from wiping and to be write film, 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, the upper surface of described polyester film and micropore adhesive layer is evenly distributed with several lug bosses, thus form at this upper surface the surface that roughness is 1.0 μm ~ 3.0 μm.
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, pore density: 1000 ~ 3000/cubic centimetre.
2, in such scheme, the thickness of described polyester film is 75 μm ~ 200 μm.
3, in such scheme, 180 ° of adhesion strengths to glass of described micropore adhesive are 0.5 ~ 1.5N/inch
3, in such scheme, the upper surface roughness of described polyester film is 1.0 μm ~ 3.0 μm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is exempted from wiping and to be write film, and 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, the upper surface of polyester film and micropore adhesive layer is evenly distributed with several lug bosses, thus form at this upper surface the surface that roughness is 1.0 μm ~ 3.0 μm, both also can put forward the sense of touch that the pad pasting that writes is write, also greatly improve viewing board angular field of view and definition.
