The electrostatic prevention label material
Technical field
The utility model relates to a kind of electrostatic prevention label material, and the information that is mainly used in the electronics manufacturing is reviewed marking materials.
Background technology
Continuous reinforcement along with electronics manufacturing enterprise's information system management, for guarantee product can be rationally in manufacture process, safety, efficiently, operation at low cost, also can review simultaneously various production informations, effectively grasp processing procedure progress and product quality, various countries progressively pay attention to the electronic product environmental issue simultaneously, especially the application popularization of leadless process, more and more higher to requiring at the electronic product marking materials, as electrostatic prevention, easily print, easily printing, scratch-resistant, antiacid alkali, viscosity are strong etc.Yet at present the electrostatic prevention label of reporting nearly all is to be the label of base material with polyimide (PI), and cost is very high.
The utility model content
The purpose of this utility model provides the electrostatic prevention label material that a kind of cost is low and performance is good, is applied to the usefulness of the permanent identification in electrostatic prevention field.
For achieving the above object, solution of the present utility model is:
A kind of electrostatic prevention label material, be to be base material with mylar (PET), electrically conductive polyaniline is applied to the wherein one side of base material, the another side that fire resistant resin printing ink is applied to base material forms coating, with the antistatic acroleic acid pressure sensitive adhesive as primer be coated on the Ge Laxin release liners as base stock on, carry out the wherein one side of the glue face of base stock and described base material compound at last.
The thickness of described base material is 30um.
The thickness of described coating is 15um.
100 ℃ of described label electrostatic prevention label material temperature resistant ranges/30s to 130 ℃/10min; Described primer surface resistivity is 104-108ohsm/sq; The sticking power of holding of described primer 〉=1000 grams.
After adopting such scheme, useful result of the present utility model is, needing the occasion of electrostatic prevention, in the unleaded process for making of electronic product, adopt polyester electrostatic prevention label to replace common polyester label and PI electrostatic prevention label, avoid of the injury of the static of process generation, also avoid adopting PI electrostatic prevention label product to cause too high manufacturing cost simultaneously, solved the problem of electronic product electrostatic prevention mark sign effectively the electronic product components and parts.

Embodiment
As shown in Figure 1 and Figure 2, the utility model has disclosed a kind of electrostatic prevention label material, is base material 2 with mylar (PET), is primer 3 with the electrostatic prevention acrylate pressure sensitive adhesive, is coating 1 with fire resistant resin printing ink, is base stock 4 with the Ge Laxin release liners.Earlier base material 2 is carried out surface electrostatic and eliminate processing, then electrically conductive polyaniline is applied to the wherein one side (not shown) of base material 2, the another side that then printing ink is applied to base material 2 forms coating 1; Then, with the permanently antistatic acrylate pressure sensitive adhesive as primer 3 be coated on the base stock 4, at last the wherein one side of the glue face of base stock 4 and base material 2 is carried out compoundly, obtain polyester electrostatic prevention label.Specifically:
A) choosing thickness is that the no blemishes polyester material of 30um free of pinholes and so on is as base material 2, it is unreeled the smooth rotation rubber tire of eliminating electrostatic apparatus through corona, adjust corresponding electric current, voltage, two-sided corona treatment is carried out in start then, being easy to of causing combines the adhesion between the raising with ink coating 1, base material 2, primer 3.
B) elder generation puts into fire resistant resin coating the frictioning groove of coating machine, and the gap of adjusting between scraper and the roller coating is 20um, open the heat button of coating machine again, baking oven one district (base material 2 enters the district) with coating machine, two districts (zone line), the temperature in three districts (base material 2 outlet areas) is controlled to be corresponding temperature respectively, open coating machine transmission button then, base material 2 is unreeled, control unreels speed, the base material 2 glue groove of passing through earlier, a side that makes fire resistant resin be coated on base material 2 equably is positive, enter coating machine oven then, the Zi Yi district enters, draw from three districts through two districts, obtain the side thickness that is cured and be the base material 2 of the ink coating 1 of 20um, stand-by.
C) the antistatic acroleic acid pressure sensitive adhesive for preparing is put into the coating groove of another coating machine, and adjust gap 15um between scraper and the roller coating, open the heat button of coating machine again, baking oven one district (base stock 4 enters the district) with coating machine, two districts (zone line), the above-mentioned trizonal temperature of control respectively in three districts (base stock 4 outlet areas), to choose thickness then is the base stock 4 of 90 grams, with certain speed coating groove of passing through, make the antistatic acroleic acid pressure sensitive adhesive be coated on the baking oven that enters coating machine on release of base stock 4 equably, the Zi Yi district enters, draw from three districts through two districts, the thickness that obtains being cured is the base stock 4 of 15um primer 3.Compound with the wherein one side of the base material 2 of step 2 gained before simultaneously in the back rolling of coating machine, make that primer 3 composite transferring are reverse side to the opposite side through ink coating 1 base material 2 of step 2 gained, just obtain removable high temperature resistant labels material.
Certainly, as shown in Figure 1, between coating 1 and base material 2, also be coated with primer 3, guarantee the fastness of coating 1.
Its performance characteristic is: 100 ℃ of electrostatic prevention label material temperature resistant ranges/30s to 130 ℃/10min; Viscose glue surface resistivity: 104-108ohsm/sq; Sticking power 〉=1000 grams of holding; Anti-certain soda acid, scaling powder and part organic solvent; Be suitable for hot transfer printing of resin carbon ribbon and UV ink printing, especially be fit to the two-dimension code sign, be widely used in Chip Packaging or discharge occasion at specific static.
