There is provided it is a kind of be not easy new type blackboard and its manufacturing method reflective, that be not easy to be stained with ash, be that those skilled in the art are badly in need of The technical problem of solution.
Summary of the invention
New type blackboard that is reflective, being not easy to be stained with ash and its production side are not easy the technical problem to be solved in the present invention is to provide a kind of Method.
In order to solve the above technical problems, new type blackboard provided by the invention, including be sequentially stacked front decoration paper layer, preceding ox Mulberry paper layer, ferroalloy parts, rear layers of kraft paper, rear decorative paper layer, the front decoration paper layer, preceding layers of kraft paper, ferroalloy parts, Through hot-forming after layers of kraft paper, rear decorative paper layer are stacked afterwards, front decoration paper layer, rear decorative paper layer coat fluorin modified crylic acid tree Rouge, polyurethane acroleic acid, HDDA, TMPTA mixture, and by the advanced row surface cure of quasi-molecule UV lamp, then carry out EB solidification After obtain.
The production method of above-mentioned new type blackboard, includes the following steps:
A, front decoration paper layer, rear decorative paper layer are prepared: facing paper being impregnated into trimethylolpropane trimethacrylate, is then dried, It is then coated with fluorin modified crylic acid resin, polyurethane acroleic acid, trimethylolpropane trimethacrylate, 1,6- hexylene glycol, two propylene The mixed solution of acid esters carries out UV solidification to the facing paper after coating using quasi-molecule UV lamp, then carries out EB solidification, then shears To obtain the decorative paper layer of required size；
B, preceding layers of kraft paper, rear layers of kraft paper are prepared: by brown paper impregnated phenolic resin, needed for then drying and shear obtaining The layers of kraft paper of size；
C, prepared by ferroalloy parts: ferroaluminium is rolled into the sheet that thickness is no more than 0.1mm, and is polished and is cleaned, Epoxy resin is coated, then drying obtains ferroalloy parts；
D, assembly: it is as front decoration paper layer, multilayer step the B layers of kraft paper obtained using the decorative paper layer that one layer of step A is obtained The layers of kraft paper that ferroalloy parts, the multilayer step B that preceding layers of kraft paper, one layer of step C are obtained are obtained is as rear layers of kraft paper, one The decorative paper layer that layer step A is obtained is laid out as rear decorative paper layer, obtains blackboard blank material；
E, hot pressing and shearing: the blackboard blank material that step D is obtained carries out hot pressing, and heating temperature is 140-145 DEG C, pressure 9- 10MPa, heat-insulating pressurizing time are 25-30 minutes, are cut after cooling, to obtain the blackboard of required size.
Further, in the step A, the mass percent of fluorin modified crylic acid resin is 25%-40% in mixed solution, is gathered The mass percent of urethane acrylic acid is 15%-30%, and the mass percent of trimethylolpropane trimethacrylate is 10%-20%, The mass percent of 1,6- hexanediyl ester is 30%-45%.
Further, in the step B, spread when brown paper impregnated phenolic resin is 30%-35%, fugitive constituent 6%- 8%。
Further, the iron aluminium mass ratio of ferroaluminium is 8:2 in the step C.
Further, in the step D, the number of plies of the preceding layers of kraft paper is 10 layers, and the number of plies of the rear layers of kraft paper is 30 layers.
The technical effect of invention: (1) production method of of the invention new type blackboard, compared with the existing technology, by it is preceding, Ferroalloy parts are set between layers of kraft paper afterwards, so that blackboard has magnetism, have both the functions such as writing scribble, decoration, storage, tool There is environment friendly and pollution-free, durable, multi-functional advantage；(2) setting of ferroalloy parts, so that blackboard has ferromagnetism, The quality and hardness of ferroalloy parts are reduced simultaneously, it is easily processed into type；(3) decorative paper layer carries out purple by quasi-molecule UV lamp Outside line lighting process so that the mattness of decorative paper layer and uniformly, can be by reduction reflective phenomenon；(4) table of decorative paper layer Face impregnates fluorin modified crylic acid resin, can reduce viscous ash；(5) solidification passes through UV in such a way that UV solidification, EB solidification combine Solidify and the surface layer of decorative paper layer is solidified, recycle EB to solidify and the internal layer of decorative paper layer is solidified, to improve decoration The hardness of paper layer adapts to prolonged write and requires；1,6- hexanediyl ester (HDDA) is a kind of solid suitable for UV light Change the acrylic ester monomer of reaction, HDDA low viscosity, the diluting power with strength has swelling effect to plastic rubber substrate, can have The promotion of effect promotes adhesive force to plastic rubber substrate, and endurance, water resistance and heat resistance are good, have excellent weather resistance；Fluorine richness propylene Acid resin and polyurethane acroleic acid have excellent wearability after solidifying, it is ensured that the service life of blackboard；(6) brown paper impregnated of A large amount of phenolic resin, the resistance to boiling water of the new type blackboard of acquisition, resistance to cracking, antibacterial and mouldproof can bear wind and weather, use occasion It is relatively wide；(7) setting of ferroalloy parts, so that new type blackboard is unlikely to deform；(8) decorative paper layer is fine and close through EB solidification rear surface, It may be adapted to the writing of free ink pen, oil pen, chalk；And it is easy wiping, it will not leave behind any trace.
