Abstract
The present invention relates to a novel magnetic writing board with a character optional modification function, which comprises two transparent high abrasion resistant plastic sheets, a middle clamping fiber metal mesh sheet and metal powder of a filler in a mesh sheet grid. The present invention is characterized in that the mixture of the metal powder and mineral oil is filled in a middle clamping fiber metal mesh sheet grid. The present invention has the formula ratio (weight percent ratio) of the mixture of the metal powder and the mineral oil of 17 to 25% of nickel powder, 1 to 5% of iron powder, 0.1 to 1% of calcium powder, 1 to 3% of zinc powder and 70 to 80% of mineral oil. A use method of the novel magnetic writing board with a character optional modification function is characterized in that after a magnetic pen is used for writing or drawing on the magnetic writing board, A character needing to be modified can be optionally erased and modified from the surface of the magnetic writing board by paper, cotton or fingers. A product of the present invention breaks through the defect that the existing product can not be partially modified. The present invention can also be made into an ultrathin type, and the use and the carrying of the present invention are extremely convenient.
Description
Technical field
The present invention relates to a kind of magnetic wordpad, particularly disclose a kind of rewritable magnetic writing board and using method thereof.
Background technology
General in the market magnetic wordpad is a lot, and is also very universal, and child learns to write, draws a picture to like and uses it.In use existing product has a very large shortcoming, when wrongly writing a word, when drawing wrong unicursal and draw, often can't locally revise, draw plate for one with magnetic wordpad inside, magnetic is erased in inboard at magnetic wordpad, certainly will wipe the word on the board, picture all like this, has to rewrite or repaint.As the utility model patent 89205040.3 disclosed blackboard eraser devices that are used for magnetic wordpad, adopt cover interlinked mechanisms such as expansion link, complex structure not only, and be difficult to the word on the board, draw and carry out part modification.Though patent 00217493.6 disclosed magnetic wordpad has been done improvement on easy-to-use, but also will be used the magnetic wiping board could realize wiping, still bring the user certain trouble in the use, convenient inadequately, and it utilizes magnetic sheet to show writing, the producing process complexity.The large-area magnetic wordpad that office uses also has similar drawback, has caused very big inconvenience and trouble to the user.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art magnetic wordpad, disclose a kind of rewritable magnetic writing board.This magnetic wordpad rewritable, if there is individual malapropism to wrongly write or write badly, can arbitrarily wipe this word, keep other correct parts, then down write then, overcome in the prior art can not revise arbitrarily at arbitrary position on magnetic wordpad drawback.
The present invention is achieved in that a kind of rewritable magnetic writing board, comprise the transparent high abrasion plastic sheet in two sides, middle clamping fibre metal net sheet and net frame inner stuffing metal powder, it is characterized in that: fill the metal powder mineral oil mixture in the middle clamping fibre metal net frame, the prescription of described metalliferous mineral oil mixture and percentage by weight are: nickel powder 17～25%; Iron powder 1～5%; Calcium powder 0.1～1%; Zinc powder 1～3%; Mineral oil 70～80%.Described metal powder mineral oil composition formula mineral oil in fluid is 150～No. 200 white oils; The fineness of nickel powder, iron powder, calcium powder, zinc powder is more than or equal to 300 orders.A kind of using method of rewritable magnetic writing board is characterized in that: after writing on the magnetic wordpad or drawing a picture, can arbitrarily wipe revisal on the magnetic wordpad surface to the literal that needs are revised with paper or cotton or finger with magnetic pen.
Advantage of the present invention is: easy to use, in use can arbitrarily wipe modification, and keep correct part, then down write; The instrument of wiping can be paper, cotton, even points and can use, and can easily wipe on the magnetic wordpad surface.This rewritable brings great convenience to the user.And product of the present invention reduces several times than traditional magnetic wordpad product thickness, can make ultrathin type, and it is convenient especially to carry, so the present invention has great practicality no matter be student, child or office's usefulness.
Description of drawings
Accompanying drawing is a structure chart of the present invention.
Among the figure: 1, bottom high abrasion plastic sheet; 2, the metal powder mineral oil mixture of middle level metallic fiber type net sheet and filling; 3, superficial layer hyalomere high abrasion plastic sheet; 4, seal around the board.
The specific embodiment
With reference to the accompanying drawings, material preparation with each layer, bottom, superficial layer high abrasion plastic sheet 1,3, can arbitrarily buy in the shop, market, middle level metallic fiber type net sheet 2 also is the commercial goods, the metal powder mineral oil mixture of filling in the net sheet prepares by said ratio (percentage by weight), metal powder fineness 〉=300 orders, and mineral oil adopts 150～No. 200 white oils; Preparation need be heated to 70 ℃～80 ℃, and stir the metal powder mineral oil mixture, plastic sheet, net sheet are bonded together bottom, superficial layer high abrasion plastic sheet three limits according to the cutting of product required size, promptly be to seal 4 parts to form the pocket form, fibrous type wire netting sheet is put in the intermediate layer.When injecting the metal powder mineral oil mixture of proportioning quantity, filler smoothed get final product, seal after vacuumizing then.Below for the various different proportionings of several embodiment metal powder mineral oil.
Embodiment 1, and metal powder mineral oil composition formula and percentage by weight that fibrous type wire netting sheet is filled are:
Nickel powder 20%;
Iron powder 5%;
Calcium powder 1%;
Zinc powder 3%;
Mineral oil 71%.
Embodiment 2, and metal powder mineral oil composition formula and percentage by weight that fibrous type wire netting sheet is filled are:
Nickel powder 17%;
Iron powder 2%;
Calcium powder 0.3%;
Zinc powder 1.7%;
Mineral oil 79%.
Embodiment 3, and metal powder mineral oil composition formula and percentage by weight that fibrous type wire netting sheet is filled are:
Nickel powder 25%;
Iron powder 3%;
Calcium powder 0.5%;
Zinc powder 1.5%;
Mineral oil 70%.
Because the special formulation of metal powder mineral oil mixture of the present invention, so word or the picture write on the board, as long as on the surface of high abrasion plastic sheet with paper, cotton, mould rod or point erasing, the literal metal powder of being wiped will come off and drop in the interior metal powder mineral oil mixture of wire netting frame, therefore form the great facility on using, simultaneously because the change of erasing mode, magnetic wordpad can be made ultrathin type, give using and carrying and created superior condition of product of the present invention, help applying.
