Abstract
The invention discloses a production process of a temperature-sensitive stripping membrane. The production process comprises the following steps of: A, producing a temperature-sensitive stripping bonding agent; B, processing a stripping layer: coating organic silicon oil onto one face of a polyester film to obtain a stripping layer; C, coating a temperature-sensitive stripping layer: coating the temperature-sensitive stripping layer bonding agent onto one surface of a substrate; and D, compounding and calendaring: compounding and calendaring the stripping layer onto the substrate which is coated with the temperature-sensitive stripping bonding agent, bonding one surface of the stripping layer which is coated with organic silicon oil with one surface of the substrate which is coated with the temperature-sensitive stripping bonding agent, and coiling. The production process has the advantages: during use, a special temperature-sensitive stripping bonding agent is foamed by heating to a specified temperature, and adhesive force of an adhesive belt disappears instantly, so that stripping is realized. Natural stripping can be realized without stressing, so that workpieces are not damaged or polluted, labor face is saved, conventional cleaning operation is avoided, and the utilization ratio of raw materials is increased.
Description
Technical field
This invention relates to temperature-sensitive and peels off the diaphragm field,
Technical background
It is a kind of adherent adhesive tape that is used for that temperature-sensitive is peeled off diaphragm, and when envrionment temperature raise, it can lose viscosity.In the various manufacturing processes of electronic product; Robotization, human-saving are turned into very big; Be widely used in: 1, transmit: transmit chip device in the production of robotization electronic product; Be used for the transmission of piezoelectric device in the electrode printing, send out the transmission of diode pin cleanup acid treatment, make travelling belt in the production and use.2, protection: the protection of lead frame punching hides protection, the protection of lead frame coating in the pickling.3, working fastening: provisional fixing part, provisional fixing in the cutting, provisional fixing etc. in the grinding and polishing process.Because temperature-sensitive is peeled off diaphragm and possessed particular performances, country finds broad application like the U.S., Japan, Korea S etc. in IT industry forward position.The at present domestic blank that still belongs to is peeled off the diaphragm production technology to temperature-sensitive abroad and is never externally revealed.
Summary of the invention
The object of the invention is peeled off the deficiency that the diaphragm production technology still belongs to blank to China's temperature-sensitive exactly, and provides a kind of temperature-sensitive to peel off the diaphragm production technique, and its production craft step is:
A, production temperature-sensitive release adhesive: the temperature-sensitive release adhesive is many component acrylics ester copolymer emulsion; Its parts by weight of raw materials proportioning is:
Alcoxyl silane propenoate or NMA mix monomer 85～90
Imidazoles curing catalysts or polymeric polyisocyanate high-temperature curing agent 3～5
Cellmic C 121 or tosic acid hydrazides whipping agent 3～6
Plastics oxidation inhibitor 0.1-0.5
Softening agent 0.1-0.5;
The above-mentioned raw materials mixing is the temperature-sensitive release adhesive;
B, processing peel ply: the one side that organic silicone oil is coated on mylar is peel ply;
C, coating temperature-sensitive peel ply: above-mentioned temperature-sensitive release adhesive is coated on the one side of base material;
D, compound calendering: on the base material that is coated with the temperature-sensitive release adhesive, the one side that peel ply is coated with organic silicone oil combines with the one side that base material is coated with the temperature-sensitive release adhesive with the compound calendering of peel ply, and last rolling gets final product.
Advantage of the present invention is: it is to have bounding force under a kind of adhesive tape that shows unique characteristics, the normal temperature that this temperature-sensitive is peeled off diaphragm.During use, only need be heated to the temperature of regulation, special temperature-sensitive release adhesive foaming, the moment forfeiture of adhesive tape adhesion, generation is peeled off.Because not afterburningly just can peel off naturally, do not damage and pollute workpiece, human-savingization, avoid the conventional clean operation, improved raw-material utilization ratio.Tear peel ply (organic silicone oil is used for conveniently tearing off peel ply) during use off,, after bonding task is accomplished, make this temperature-sensitive peel off diaphragm with the mode of heating and peel off automatically then with the adhering part that the temperature-sensitive release adhesive is arranged.

Accompanying drawing 1 is peeled off the bounding force graphic representation of diaphragm under differing temps for this temperature-sensitive.
Embodiment
Production craft step of the present invention is:
A, production temperature-sensitive release adhesive; The temperature-sensitive release adhesive is many component acrylics ester copolymer emulsion; With alcoxyl silane propenoate or NMA mix monomer 85kg, imidazoles curing catalysts or polymeric polyisocyanate high-temperature curing agent 3kg, Cellmic C 121 or tosic acid hydrazides whipping agent 4kg, plastics oxidation inhibitor (is the commercially available prod; Select complex type antioxidant for use: the mixture of hindered phenol and phosphorous acid ester, monothioester) 0.3kg, softening agent (are the commercially available prod; Select electrical grade DOP for use) the 0.3kg mixing the temperature-sensitive release adhesive, also can add stopping composition (light calcium carbonate or talcum powder) 0.3kg and an amount of colorant.
B, coating peel ply: the one side that organic silicone oil is coated on mylar is peel ply;
C, coating temperature-sensitive peel ply: above-mentioned temperature-sensitive release adhesive is coated on the one side of base material (polyethylene terephthalate);
D, compound calendering: on the base material that is coated with the temperature-sensitive release adhesive, the one side that peel ply is coated with organic silicone oil combines with the one side that base material is coated with the temperature-sensitive release adhesive with the compound calendering of peel ply, and last rolling gets final product.
This temperature-sensitive is peeled off diaphragm under normal temperature normality condition, and temperature-sensitive release adhesive clinging power is stable, initial bonding strength 10～12# steel ball peeling force 500 ± 50g/20mm, confining force NC/3600 second.(after test condition was the mixed emulsion dispersion grinding, coating PET base material dry coating 45～50um covered and is coated with the silicon mucous membrane).Be heated to 90～120 ℃, during 10～30 seconds time, it is zero that temperature-sensitive release adhesive mucous membrane cohesive force disappears, and foaming simultaneously thickens, and temperature-sensitive is peeled off diaphragm and peeled off automatically, can not cause residual contamination or damage to the adherend body.
