Examples
A smooth high-precision film for printing and outputting drawings comprises a base material, wherein the base material is PET or PVC with the thickness of 100-200 mu m. PET is an amorphous, odorless, nontoxic and highly transparent colorless or micro-color thermoplastic engineering plastic, has excellent physical and mechanical properties, particularly excellent impact resistance, high tensile strength, bending strength and compression strength, small creep property and stable size; the flame-retardant polyester resin has good heat resistance, low temperature resistance, electrical property and flame retardance, can be used for a long time at minus 60-120 ℃, has no obvious melting point, and is in a molten state at 220-230 ℃; because the molecular chain rigidity is large, the resin melt viscosity is large, the water absorption rate is small, the shrinkage rate is small, the film permeability is small, and the film belongs to a self-extinguishing material; good weather resistance, oil resistance and acid resistance; based on the performance of the PET material, the PET is selected as the base material, so that the mechanical properties of the film, such as dimensional stability, heat resistance, weather resistance, strength, wear resistance and the like, can be improved. The PVC film has the characteristics of high transparency, good glossiness, high softness, oil resistance, good solvent resistance, printing and the like, so that the PVC film can be used as a base material.
The front surface of the base material is provided with an ink absorption layer, and the ink absorption layer comprises 0.01-0.2% of cross-linking agent, 0.01-1% of surfactant, 1.0-5.0% of PVA, 5-20% of nano-alumina or silicon dioxide and the balance of water by mass percent. The cross-linking agent is aldehyde, borax or boric acid, such as one or more of formaldehyde, acetaldehyde, glyoxal, borax, boric acid and sodium borate. The surfactant is fluorocarbon or polyether, such as 3-hexafluoropropylene oxide amido propyl (2-sulfurous acid) ethyl dimethyl amine or 8-3-9 fluorocarbon-carbon hydrogen flexible bridge mixed chain double quaternary ammonium. The silicon dioxide microporous gel resin or the nano water-based alumina not only forms a plurality of microporous pores among the particles in the ink absorption coating, but also can form a microporous network because the silicon dioxide particles contain a plurality of micropores inside, the total porosity is greatly increased, the microporous network can firmly fix ink drops, the ink absorption capacity is enhanced, the excellent image quality can be ensured, the drying time can be shortened, the ink can be collected without waiting for the complete drying of the ink, the ink is contained in the pores, and dye molecules or pigment particles are embedded at the outlets of the pores, so that the pollution can not be caused.
