Description
Technical field
The present invention relates to pressure sensitive adhesive technical field, particularly relate to a kind of pressure sensitive adhesive being applied to ultrathin double-face glue and preparation thereof
Method.
Background technology
Pressure sensitive adhesive goods are widely used in packaging, electric appliance and electronic, building, health care, automobile and family life articles for use etc.
Industry-by-industry, plays various bonding effects such as tying up, protect, seal, insulate and fix.In recent years, electronic product is the most generally adopted
Replace conventional screw as combine component with structure glue or double faced adhesive tape, therefore, answer the thinness of electronic product to design, for two-sided
The gross thickness of glue also has the requirement of slimming.But, the acrylic acid that employing is traditional mostly of PET double faced adhesive tape the most on the market is molten
Dosage form glue prepares, and thickness is mostly 30 ~ 50um, if reducing the coating thickness of acrylic acid solvent-borne type glue, adhesion is the most therewith
Decline, and the performance requirement of general electronic products assembling double faced adhesive tape at least needs the adhesion of 1kg/in, if using traditional
When the double faced adhesive tape product that gross thickness is below 15um made by acrylic acid solvent-borne type glue, its adhesion the most only can reach 500 ~
800g/in.Therefore, there is the problem of the demand that cannot concurrently reach slimming, high adhesion in existing double faced adhesive tape, the above
Problems demand solves.
Summary of the invention
Present invention aims to the deficiencies in the prior art, and a kind of high adhesion is provided be applied to ultrathin double-face
Pressure sensitive adhesive of glue and preparation method thereof.
The present invention is achieved through the following technical solutions.
