Abstract

The invention relates to a method for manufacturing a shape memory anti-counterfeiting label, which is characterized by comprising the following steps of: performing cross-linking, extrusion or injection molding on a high polymer material with a shape memory function in a charging barrel of an extruder or an injection molding machine by a peroxide cross-linking process or one-step silane cross-linking process to make a product directly have the memory function, wherein an extruded sheet can be a plane sheet and can also be a sheet with concave-convex patterns and characters on the surface; and heating the cross-linked sheet to over the deformation temperature thereof, pressing the patterns or characters on the plane sheet, or pressing the sheet with the concave-convex patterns or characters into a plane or other patterns and characters, and cutting the sheet into slices, wherein each slice contains one pattern or a group of characters. Sheet molding (or injection molding) and chemical cross-linking are performed simultaneously, so a manufacturing process is simplified and cost is saved.

Description

A kind of method for making of shape memory anti-counterfeiting label
Technical field
The present invention relates to the method for making of a kind of method for making, particularly a kind of shape memory anti-counterfeiting label.
Background technology
Disclose name in the one Chinese patent application (number of patent application 201010125727.4) and be called " a kind of method for making of shape memory anti-counterfeiting label "; Its utilizes has the high molecular polymer of SME this characteristic of memory to its figuration, can be implemented in false proof on the object such as bottle lid.Its processing step is: the macromolecular material that will possess shape memory function is earlier processed the sheet material that the surface has uneven pattern, more above-mentioned sheet material is carried out cross-linking radiation.The technology more complicated.
Summary of the invention
Sheet material processed by the macromolecular material that the object of the present invention is to provide a kind of handle to possess shape memory function and two crosslinked technological processs unite two into one, and has simplified manufacturing process, the method for making of the shape memory anti-counterfeiting label that provides cost savings.
The object of the invention can reach through following measure: a kind of method for making of shape memory anti-counterfeiting label; It is characterized in that: the macromolecular material that will possess shape memory function adopts peroxide crosslinking technology or one-step method silanes crosslinked technology; In the barrel of extruder or injection machine, carry out crosslinkedly, extrude or the product of injection mo(u)lding has directly just had Memorability, the sheet material of extruding can be a plane sheets; It also can be the sheet material that the surface forms relief pattern or literal; Be heated to it to above-mentioned crosslinked sheet material more than the deformation temperature again, and on plane sheets, suppress pattern or literal, or be pressed into plane or other pattern, literal to the sheet material that forms relief pattern or literal; Be cut into small pieces to sheet material again, each small pieces has all implied a pattern or one group of literal gets final product.
The object of the invention can also reach through following measure: described extrude or injection molding process in; The knurling rolls of sheet extruder group capable of using form relief pattern or literal in the sheet surface of extruding; Or utilize mould directly to form relief pattern or literal on the surface of injecting products; Be heated to it to above-mentioned crosslinked sheet material more than the deformation temperature again, the pattern or the literal that are pressed into other with relief pattern on the sheet material of two rollers or the heating of tri-roll press machine handle or literal then, or be pressed into the plane; Be cut into small pieces to sheet material again, each small pieces has all implied a pattern or one group of literal gets final product.Described extrude or injection molding process in; The macromolecular material that will possess shape memory function is extruded into plane sheets; Sheet material is cut into required specification by the size of hot pressing die, then sheet material is put into hot pressing die, extrude relief pattern or literal at the surface heat of sheet material.Described extruder can adopt single screw rod sheet extruder group; The roller surface of single screw rod sheet extruder group has been set a plurality of identical patterns or has been organized identical literal more; Pattern that these are identical or literal have certain distance each other, and pattern that these are identical or literal are protrusions or recessed.The sheet material that has relief pattern or literal to above-mentioned crosslinked surface strikes out the relief pattern of sheet material or literal with punch press and mould other pattern or literal under the situation of normal temperature.The thickness of said plane sheets is 0.1-2.0mm.Said thickness with sheet material of uneven pattern is 0.1-2.0mm.
The present invention compares prior art and has following advantage: carry out sheet forming (or injection mo(u)lding) and chemical crosslinking simultaneously, simplified manufacturing process, provide cost savings.
Embodiment
The present invention below will combine embodiment to make further detailed description:
Embodiment one
Utilize single screw rod sheet extruder group, the roller surface of this sheet extruder group has been set a plurality of identical patterns or has been organized identical literal more, and pattern that these are identical or literal have certain distance each other, and pattern that these are identical or literal are protrusions or recessed.The macromolecular material that will possess shape-memory properties with such sheet extruder group; As employing peroxide crosslinking technology or one-step method silanes crosslinked technologies such as ENB, using trans-polyisoprene, polyurethane, SB, tygon, in the barrel of extruder, carry out crosslinked; And be extruded into the surface and have the relief pattern corresponding or the sheet material of literal with roller; Sheet thickness is 0.1-2mm, with 0.3-0.5mm for well.Above-mentioned crosslinked sheet material heating, flatten relief pattern on the sheet material of heating or literal with two rollers or tri-roll press machine then, with the sheet material printing, be cut into small pieces to sheet material again, each small pieces has all implied a pattern or one group of literal.Be attached to these small pieces on the commodity, when needs are checked the true and false of commodity, put into small pieces in the boiling water or heating otherwise, then these small pieces will show pattern or the literal on the roller, play false proof effect.
Embodiment two
To possess macromolecular material such as ENB, using trans-polyisoprene, polyurethane, SB, ethene-vinyl acetate polymkeric substance, tygon of shape memory function etc.; Adopt peroxide crosslinking technology or one-step method silanes crosslinked technology, in the barrel of injection machine, make these materials crosslinked, utilize mould directly to form relief pattern (literal) again on the surface of injecting products.When being heated to it to injecting products more than the deformation temperature; The pattern (literal) that its surface has been formed; Be pressed into other pattern (literal), or be pressed into the plane, be heated to its deformation temperature to these products again when above again, the relief pattern (literal) that injection moulding forms will display again.
