Removable high temperature resistant labels material
Technical field
The utility model relates to a kind of removable anti-high 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 temporary mark material requirements at goods, strong as high temperature resistant, easy printing, easily printing, scratch-resistant, antiacid alkali, viscosity, the most important is exactly a cull not.Yet at present the high temperature resistant labels material of reporting nearly all is the removable label of nonvolatil acrylate glue material and common non-refractory, all is unsuitable for the unleaded temporary mark that is manufactured on goods of electronic product.
The utility model content
The purpose of this utility model provides a kind of removable high temperature resistant labels material, satisfies the temporary mark requirement of the unleaded manufacturing of electronic product.
For achieving the above object, solution of the present utility model is:
A kind of removable high temperature resistant labels, be to be base material with the Kapton, the wherein one side of high temperature resistant resin printing ink being coated base material forms coating, the compound primer of modified organic silicon is coated on the another side of base material, carries out release of PET release film and primer glue face on the base material compound at last.
The thickness of described base material is 25 microns.
The thickness of described coating is 20 microns.
The removable primer of described modified organic silicon, its thickness are 25 microns.
The thickness of described PET release film is 75 microns.
After adopting such scheme, useful result of the present utility model is, in the unleaded process for making of electronic product, adopt removable high temperature resistant bar code mark material to replace common removable label, avoid the glue of label and the phenomenon that coating comes off or bubbles because of non-refractory causes, simultaneously avoid adopting permanent acrylate glue to cause a large amount of cull phenomenons, the temporary mark that has solved effectively at goods does not have the problem that material can be used yet.

Embodiment
As shown in Figure 1 and Figure 2, the utility model has disclosed a kind of removable high temperature resistant labels material, is to be base material 2 with Kapton (PI), with the removable glue of modified organic silicon as primer 3, with high temperature resistant resin printing ink is coating 1, is base stock with PET release film 4.The wherein one side of high temperature resistant resin printing ink being coated base material 2 forms coating 1, primer 3 is coated on the another side of base material 2, carries out 4 release of PET release films and primer 3 on the base material 2 compound at last.Specifically:
A) choosing thickness is that the no blemishes polyimide material of 25um 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 with ink coating 1, base material 2, the removable primer 3 of organosilicon, improves the adhesion between them.
B) earlier mixed and modified resin coating is put into coating frictioning groove, and the gap of adjusting between scraper and the roller coating is 25um, 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), three districts (outlet area of base material 2) handle the above-mentioned trizonal printing ink of process under the control corresponding temperature, open coating machine transmission button then, base material 2 is unreeled with certain speed, the base material 1 glue groove of passing through earlier, a side that makes mixed and modified resin coating 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) will prepare the coating groove that modified organic silicon glue is put into another coating machine, and adjust gap 30um between scraper and the roller coating, open the heat button of coating machine again, baking oven one district (release liners enters the district) with coating machine, two districts (zone line), the temperature in three districts (release liners outlet area) is controlled respectively, base material 2 another sides (being non-printing ink face) are with the certain speed coating groove of passing through then, make modified organic silicon glue equably on the another side of coated substrate 2, enter the baking oven of coating machine, the Zi Yi district enters, draw from three districts through two districts, the thickness that obtains being cured is the removable primer 3 of modified organic silicon of 25um.To be that the release face of the PET release film 4 of 75um carries out compound with choosing thickness simultaneously in the back rolling of coating machine, just obtains 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: 270 ℃/10min of material temperature resistant range, 320 ℃/10S; Withstand voltage 5KV; Clinging power 4N/25mm, coating 1 is suitable for hot transfer printing of resin carbon ribbon and UV ink printing; Product easily tears, does not have obvious cull.
