Abstract
The invention relates to a magnetic drawing board core and filling suspending liquid thereof. The magnetic drawing board comprises a face board layer, a grid interlayer and a bottom board layer which are arranged from the top to the bottom and connected orderly. Suspending liquid which is filled in the grids of the grid interlayer contains following material measured by weight proportion: 55-56 portions of white oil, 2.5-3.8 portions of titanium pigment, 2.0-3.0 portions of white carbon black, and 28.5-40.5 portions of magnetic powder. The magnetic drawing board core provided by the invention can be used to assemble all types of white-black drawing boards, colorful drawing boards and voice drawing boards. Compared with a dry microcapsule board core, the magnetic drawing board core has low cost, and the advantages of high definition, long service life and nontoxicity when being used in writting and drawing.
Description
Technical field:
The suspending liquid that the present invention relates to a kind of magnetic drawing board core and be used to fill the magnetic drawing board core grid.
Technical background:
Magnetic drawing mainly is made up of drawing board and paintbrush two parts, and drawing board then is made up of plate core, bodice working of plastics and magnetic eliminating bar three parts, and the plate core then is made of panel layer, grid interlayer and backplane level.In the grid of grid interlayer, fill the medium that contains magnetic.Existing mass ratio plate core preferably is the dryness microcapsules plate core of import, but costs an arm and a leg, and is difficult to penetration and promotion.
Summary of the invention:
The objective of the invention is to overcome the weak point of above-mentioned dryness microcapsules plate core, provide a kind of write clear, the life-span is long, cost is low and Product Safety and the feature of environmental protection meet the magnetic drawing board core and the filling suspending liquid thereof of relevant requirements.
Magnetic drawing board core of the present invention comprises the panel layer, grid interlayer and the backplane level that are provided with and connect successively from top to bottom, filling suspending liquid in the grid of grid interlayer, and described suspending liquid comprises following materials of weight proportions: white oil 55-65; Titanium dioxide 2.5-3.8; White carbon black 2.0-3.0; Magnetic 28.5-40.5.
The present invention, described magnetic generally is the black magnetic, also can be coloured magnetic powder, for example red magnetic, green magnetic, blue magnetic, yellow magnetic.
The present invention can be divided into the grid of described grid interlayer several sub-districts, and alternate filling contains the suspending liquid that fills of different colours magnetic on each little subregion, constitutes colored drawing board core.
The present invention, with dryness microcapsules plate core relatively, with low cost, and writing, when drawing a picture, having the sharpness height, the life-span is long and characteristics such as nontoxic.
Description of drawings:
Fig. 1 is the structure principle chart of embodiment drawing board core.
Among the figure, 1, panel layer 2, grid interlayer 3, backplane level 4, suspending liquid.
Embodiment:
Embodiment 1: the suspending liquid that is used to fill the magnetic drawing board core grid.
Suspending liquid is made up of the raw material of following weight ratio: white oil 60; Titanium dioxide 3.0; White carbon black 2.5; Magnetic 34.5.Magnetic pressing board core requires to choose black magnetic, red magnetic, green magnetic, blue magnetic or/and yellow magnetic.The product that coloured magnetic powder can select for use Taixing City Bo Kangte building materials company limited to provide; White oil can select that Fuda, Hangzhou material petrochemical industry company limited provides for use 10
#White oil.
Above-mentioned raw materials through being up to the standards is mixed in stirrer by formula ratio, promptly get suspending liquid.
Embodiment 2: magnetic drawing board core.
PVC backplane level 3 and grid interlayer 2 are obtained grid backplane level semi-manufacture through bonding process, after will obtaining grid backplane level semi-manufacture, pour into embodiment 1 resulting suspending liquid 4, and then bonding PVC panel layer 1, the semi-manufacture that glue are welded to ultrasonic drilling machine, obtain magnetic drawing board core (as shown in Figure 1) after the welding.If the magnetic drawing board core of producing is colored drawing board core, then at first the grid interlayer is divided into some sub-districts on request, pour into the suspending liquid that contains coloured magnetic powder on request in each sub-district again, the color that pours into the coloured magnetic powder of suspending liquid on each little subregion is alternate processing.
Embodiment 3: magnetic drawing.
Magnetic drawing board core that embodiment 2 is obtained and drawing board bodice plastic parts and magnetic eliminating bar are assembled into drawing board, mix paintbrush, and the packing back is a finished product.Magnetic drawing comprises black and white drawing board, colored drawing board and voice drawing board.Present embodiment is except that the plate core, and remaining part and assembly technology are identical with existing magnetic drawing.
Claims (5)
1. a magnetic drawing board core comprises the panel layer, grid interlayer and the backplane level that are provided with and connect successively from top to bottom, it is characterized in that: filling suspending liquid in the grid of grid interlayer, and described suspending liquid comprises following materials of weight proportions: white oil 55-60; Titanium dioxide 2.5-3.8; White carbon black 2.0-3.0; Magnetic 34.5-40.5.
2. magnetic drawing board core according to claim 1 is characterized in that: described magnetic is a coloured magnetic powder.
3. magnetic drawing board core according to claim 2, it is characterized in that: the grid of described grid interlayer is divided into several sub-districts, alternate filling contains the suspending liquid of different colours magnetic on each little subregion, and the color that pours into the coloured magnetic powder of suspending liquid on each little subregion is alternate processing.
