Abstract
The utility model relates to writing panel technical field, refer in particular to a kind of safe blank containing polyvinyl butyral resin, comprise glass plate, be provided with between layer glass plate two-layer more than PVB film, layer of metal wire netting is provided with between any two-layer PVB film, described PVB film is the white PVB film of porcelain, have durable in use, fluent writing, writing is clear, easy-to-write and erasable, not reflective, moistureproof, never be out of shape, never there is the situation of wiping not fall, available magnetite fixes paper on blank, when projection screen uses, light source condenses more, no longer include light source deficiency, color is out of focus, the irregular problem of curtain, because PVB film has the effect of buffering, alluvium can be stoped to penetrate, prevent glass breakage, security is good, be applicable to writing panel or curtain plate.
Description
Technical field
The utility model belongs to writing panel or curtain plate technique field, refers in particular to a kind of safe blank containing polyvinyl butyral resin.
Background technology
The glass blackboard for education of current use is generally the frosted glass of the band frosting of black, in order to allow, to write more clear General Requirements frosting comparatively coarse, but so, Dust Capacity when writing is larger, and it is comparatively difficult when wiping, need firmly wiping ability erasing writing content completely, and easily produce a large amount of dust when erasing, dust can affect the respiratory health of teacher and classmates.
In order to reduce the pollution that dust brings, also have a kind of using the import baking vanish white steel plate of color coated steel sheet or new material composite plate as panel on the market, there is good humidity resistance and no dust pollution, but composite board of long duration there will be to be heaved, be out of shape, impact is write and later stage blackboard clean.
Summary of the invention
The purpose of this utility model is to provide that a kind of dust pollution is low, impact resistance is strong, plate face stability and the good safe blank containing polyvinyl butyral resin of security.
The purpose of this utility model is achieved in that
Containing the safe blank of polyvinyl butyral resin, comprise glass plate, be provided with between layer glass plate two-layer more than PVB film, between any two-layer PVB film, be provided with layer of metal wire netting, described PVB film is the white PVB film of porcelain.
The thickness of above-mentioned single-glass plate is 1-10mm.
The thickness of above-mentioned single-glass plate is 2mm.
The thickness of above-mentioned PVB film is at least 0.38mm.
Above-mentioned metallic iron silk screen is at least 120 orders.
Above-mentioned PVB film has two-layer, and the structure of described glass plate, PVB film, metallic iron silk screen is the glass plate, PVB film, metallic iron silk screen, PVB film, the glass plate that set gradually.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model is durable in use, fluent writing, writing are clear, easy-to-write and erasable, not reflective and no dust pollution, protection against the tide, be never out of shape, and never occurs the situation of wiping not fall.
2, in the utility model metallic iron silk screen add the using function adding blank, the paper of magnetite on blank needed for fixing teaching can be adopted.
3, the utility model can serve as projection screen use, and it can make projection light source more condense, and no longer as having on traditional curtain, light source is not enough, color is out of focus, the irregular problem of curtain.
4, the utility model is when being subject to external blow, because PVB film has the effect of buffering, alluvium can be stoped to penetrate, even if glass breakage, also similar araneose crackle in small, broken bits can only be produced, its fragment firmly sticks on PVB film, and can avoid the personal injury because glass breaking causes, security is good.
5, the utility model is applicable to writing panel or curtain plate.
Accompanying drawing explanation
Fig. 1 is profile of the present utility model.
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1:
A kind of safe blank containing polyvinyl butyral resin, comprise glass plate 10, be provided with between layer glass plate 10 two-layer more than PVB film 20, between any two-layer PVB film 20, be provided with layer of metal wire netting 30, described PVB film 20 is the white PVB films of porcelain.
The thickness L1 of above-mentioned single-glass plate 10 is 1-10mm.
The thickness L1 of above-mentioned single-glass plate 10 is preferably 2mm.
The thickness L2 of above-mentioned PVB film 20 is at least 0.38mm.
Above-mentioned metallic iron silk screen is at least 120 orders, and namely per inch metallic iron silk screen has 120 grid lines or 120 meshes.
Above-mentioned PVB film has two-layer, and the structure of described glass plate 10, PVB film 20, metallic iron silk screen 30 is the glass plate 10, PVB film 20, metallic iron silk screen 30, PVB film 20, the glass plate 10 that set gradually.
Making of the present utility model: according to the order of glass plate 10, PVB film 20, metallic iron silk screen 30, PVB film 20, glass plate 10 carry out structure close sheet, conjunctions sheet is put into vacuum bag first carry out cold-draw, then heat take out make PVB film, glass and metallic iron silk screen conjunction as a whole; Or conjunction sheet is put into roll squeezer and carries out roll-in exhaust, then enter autoclave under the influence of high pressure and temperature, final products of the present utility model can be obtained.
The white PVB film of described porcelain is made adding titanium dioxide in PVB film stock, PVB film has transparent PVB film according to purposes difference, milky white PVB film, grey PVB film, the white PVB film of porcelain, blue zone PVB film, greenbelt PVB film, silk-screen PVB films etc., described glass plate is general float glass plate.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
