Description

Paste formula used repeatedly doodle board

Technical Field

The utility model relates to a scribble board especially relates to a paste formula used repeatedly scribble board.

Background

The pasting type doodle board is an information display tool capable of repeatedly writing and wiping, has the advantages of space saving, convenience in cutting, dust free, environmental protection and the like, can be directly pasted on various planes during use, and is widely applied to schools and families. However, with repeated writing and wiping, the writing layer of the doodle board is gradually worn, the adhesive doodle boards in the market at present are integrally designed, and can only be integrally discarded after the writing layer is worn, so that waste is caused, and improvement on the situation is needed.

Disclosure of Invention

The utility model discloses to defects such as the design of doodle board integral type, wasting of resources who exists among the prior art, provide a new formula used repeatedly doodle board of pasting.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

the utility model provides a paste formula used repeatedly doodling board, from up including in proper order from type layer, gum layer, magnetic layer, writing the layer down, still include the replacement layer, the layer is write including iron powder layer, replacement to the replacement layer, the replacement layer dismantlement formula install in write on the layer, the magnetic layer has spread magnetic powder, first elastic particle, it is first wear-resisting face to write the layer surface, the replacement is written the layer surface and is the wear-resisting face of second.

The iron powder layer in the replacement layer can be adsorbed on the writing layer under the action of the magnetic layer, so that the replacement layer and the writing layer can be detachably mounted. Because the replacement layer and the writing layer are detachably mounted, the replacement layer can be covered on the writing layer after the writing layer is worn, and the replacement writing layer replaces the writing layer to play a writing function. Meanwhile, the main body structures of the magnetic layer and the iron powder layer are made of modified materials of leftover materials of the PC/PMMA composite board, so that the magnetic composite board is green and environment-friendly, and the cost is saved.

The utility model discloses writing that can relapse and cleaning can cover one deck replacement layer after writing the layer wearing and tearing, need not wholly abandon the whole graffiti board of original wearing and tearing, increase of service life. In addition, if the replacement layer is worn again, the worn replacement layer can be taken down and replaced by a new replacement layer, and the whole using process is more environment-friendly. Meanwhile, the distance between the replacement layer and the magnetic layer is not increased in the replacement process of the replacement layer, so that the adsorption force between the magnetic layer and the iron powder layer is not reduced along with the increase of the replacement times.

Preferably, in the pasting type reusable doodle board, the iron powder layer is interspersed with the iron powder and the second elastic particles.

The iron powder dispersed in the iron powder layer may be attracted by the magnetic force of the magnetic layer so that the substitution layer may be adsorbed on the writing layer.

Preferably, the first elastic particles and the second elastic particles are made of rubber.

Choose for use rubber as the material of first elastic particle, second elastic particle, make the utility model discloses have certain elasticity and pliability, write and experience better, difficult rupture.

Preferably, the pasting type reusable doodle board is characterized in that the replacement writing layer and the writing layer are further dispersed with toner.

Write the layer and have higher aesthetic property, improve with the replacement that has toner the utility model discloses the side cross-section after tailorring is pleasing to the eye degree.

Preferably, in the above-mentioned pasting type reusable doodle board, the first wear-resistant surface and the second wear-resistant surface are made of polyurethane-methyl methacrylate copolymer modified resin, and the hardness of the first wear-resistant surface and the hardness of the second wear-resistant surface are 3H.

Polyurethane-methyl methacrylate copolymerization modified resin possesses certain hardness, chooses polyurethane-methyl methacrylate copolymerization modified resin for use and can increase as the preparation material of first wear-resisting face and second wear-resisting face the utility model discloses life.

Preferably, the first wear-resistant surface has a roughness of Ra3.5-10um, and the second wear-resistant surface has a roughness of Ra3.5-10 um.

This interval roughness can be guaranteed the utility model discloses better writing experience has.

fig. 2 is a schematic structural view of the replacement layer and the writing layer of the present invention in a laminated state.

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings 1-2 and the detailed description, which are not intended to limit the invention:

example 1

The utility model provides a paste formula used repeatedly doodling board, from up including in proper order from type layer 1, gum layer 2, magnetic layer 3, writing layer 4 down, still include replacement layer 5, replacement layer 5 includes iron powder layer 51, replacement and writes layer 52, replacement layer 5 dismantlement formula install in write on the layer 4, magnetic layer 3 has spread magnetic powder, first elastic particle 6, it is first wear-resisting face 41 to write 4 surfaces on the layer, the replacement is written the layer 52 surface and is the wear-resisting face 521 of second.

Preferably, the iron powder layer 51 is interspersed with the iron powder and the second elastic particles 7.

Preferably, the first elastic particles 6 and the second elastic particles 7 are made of rubber.

Preferably, the replacement writing layer 52 and the writing layer 4 are further dispersed with toner.

Preferably, the first wear-resistant surface 41 and the second wear-resistant surface 521 are made of urethane-methyl methacrylate copolymer modified resin, and the hardness of the first wear-resistant surface 41 and the second wear-resistant surface 521 is 3H.

Preferably, the roughness of the first wear-resistant surface 41 is Ra3.5-10um, and the roughness of the second wear-resistant surface 521 is Ra3.5-10 um.

During the use, at first tear off type layer 1 and expose gum layer 2, paste the gum layer 2 that will expose on wall or other planes, magnetic layer 3 and write layer 4 and be fixed to the wall together with gum layer 2 this moment, and replacement layer 5 is put on one side for subsequent use this moment. In writing, a user may write and wipe directly on the first wear surface 41 of the writing layer 4.

After the writing layer 4 is worn along with the use, the standby replacement layer 5 is taken out and attached to the writing layer 4, at the moment, the iron powder layer 51 is firmly adsorbed on the writing layer 4 under the action of the magnetic force of the magnetic layer 3, a user can directly write and wipe on the second wear-resistant surface 521 of the replacement writing layer 52 during writing, after the replacement layer 5 is worn along with the use, the worn replacement layer 5 can be taken out, the steps are repeated, a new replacement layer 5 is additionally taken out and replaced, and the repeated use is realized.
