CN201534410U - Ultra-fine flow filter-type thermo-sensitive version paper - Google Patents

Abstract

The utility model relates to ultra-fine flow filter-type thermo-sensitive version paper, which comprises a fiber layer (1), an ultra-fine flow filtering layer (2) and a thin film layer (3), and is characterized in that the fiber layer (1) is arranged at uppermost layer and mainly used for reinforcing the toughness, the tension and the printing ink absorptivity of the version paper material; the ultra-fine flow filtering layer (2) is arranged between the fiber layer (1) and the thin film layer (3) and used for bonding and filtering printing ink; and the thin film layer (3) is arranged below the ultra-fine flow filtering layer (2), so as to form ink holes of the paper. The utility model has the benefits that the version paper has technical characteristics such as high strength, no deformation, and uniform printing ink seepage, can be used for thousands of continuous times of printing, and has the advantages of no deformation and no paper damage.

Description

Ultra tiny traffic filtering type temperature-sensitive print paper

Technical field

The utility model relates to a kind of office consumptive material, a kind of specifically ultra tiny traffic filtering type temperature-sensitive print paper that is applicable to the all-in-one printing.

Background technology

The temperature-sensitive print paper performance is the principal element of decision all-in-one printing quality, domestic temperature-sensitive print paper structure is composited by adhesive by cotton paper or paper pulp and film, because fiber is entangled with on the one hand, the different chemical character of resin in the adhesive layer on the other hand, cause its strike through inhomogeneous and influence printing quality, it is unclear writing usually to occur, ghost image is arranged even also can occur the overlapping phenomenon of writing sometimes.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, the ultra tiny traffic filtering type temperature-sensitive print paper that printing quality is high.

The technical scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises fibrage (1), ultra tiny traffic filtering layer (2), thin layer (3), it is characterized in that fibrage (1) is arranged on the superiors, major function is for strengthening toughness, pulling force and the ink absorption of version paper material, ultra tiny traffic filtering layer (2) is arranged between fibrage (1) and the thin layer (3), and ultra tiny traffic filtering layer (2) plays effect bonding and that filter printing ink; Thin layer (3) is arranged on the below of ultra tiny traffic filtering layer (2), forms the black hole of paper.Preparing required critical material is:

1. the selection of thin layer thermosensitive film material: thermosensitive film should have thermoplasticity, and is easy to be punctured by the all-in-one thermal head, also should have suitable hot strength, elongation at break and percent thermal shrinkage simultaneously.Data shows: when the heat-shrinkable thick resin film too hour, the deflection of thermal stencil is smaller, can make the transmission difficulty of paraffin paper in the printing machine; When the heat-shrinkable thick resin film was too big, to such an extent as to the heat of the sensitiveness of paraffin paper meeting variation platemaking machine is delivered on the paraffin paper, perforation became very difficult on paraffin paper.So preferred heat-shrinkable thickness of resin film is 1.2～1.8 μ m, it is that polyester film and the crystallinity index of 12.6～46.1kJ/kg is not more than 30% polyester film that the type of film is generally used melting heat.

2. the selection of fibrous sheet material: need have following function: the absorbability that can strengthen toughness, pulling force and the printing ink of version paper material for the fibrous paper in the version paper.This just requires selected fibrous paper fineness height, and gas permeability is moderate.

The selection of 3. ultra tiny traffic filtering layer material: after selecting good material, one of its key technology is exactly a paper---mould the preparation of intermediate layer material, this also is the core technology of this problem, as temperature-sensitive print paper paper---mould compound articulamentum, must possess good cementability, plasticity and resistance to water, its softening point temperature requires more than 105 ℃; The junctional membrane of Xing Chenging should be microporous barrier simultaneously, plays ultra tiny filtration.

The beneficial effects of the utility model are, this kind paper should have technical characteristics such as intensity height, indeformable, printing ink ooze out evenly, can print advantages such as indeformable, not bad version continuously thousands of times.
