Description
Technical field
The invention belongs to pressure sensitive adhesive technical fields, and in particular to a kind of pressure sensitive adhesive.
Background technique
Adhesive tape mainly by substrate and is coated on one or two surface of substrate and is coated with one layer of sticker and constitutes, and passes through
Bond is formed between adhesion agent molecule and article surface molecule on base material, so that adhesive tape only adheres to the surface of article
On.It is divided by function, adhesive tape can be divided into high temperature gummed tape, pressure sensitive adhesive tape, insulating tape, specialty tape, cross cutting adhesive tape etc..Its
In pressure sensitive adhesive tape refer to using pressure sensitive adhesive that as sticker, be commonly called as Pressure sensitive adhesive tape, having can be easily when using smaller pressure
Adhesion effect can be played in adhesion, short time, and is not easy to remain on the article adhered after removing, and patch is staggered the time and can also be repaired again
Just, the advantages that rear glue surface adhesive performance will not subside substantially is used for multiple times, therefore pressure sensitive adhesive tape is in packaging, printing, automobile, family
The industries such as electricity, electronics, medical treatment, aviation, building and telecommunication equipment are used widely.
However adherence of the rubber pressure-sensitive adhesive in PET base material show always it is poor, it is well known that it is permanent to realize
Fixed or protecting effect does not require nothing more than rubber pressure-sensitive adhesive with good initial adhesion power and cohesive force, while requiring rubber
Type pressure sensitive adhesive cannot remain in and be attached on article surface from having good fissility when being attached article sur-face peeling,
If therefore adherence of the rubber pressure-sensitive adhesive in PET base material is poor, the fissility that will lead to rubber pressure-sensitive adhesive is poor.It is existing
Technology is general using first passing through sided corona treatment in advance to PET base material in order to improve the fissility of the adhesive tape, then that rubber-type is pressure-sensitive
Glue is coated in PET base material, although in a short time, rubber pressure-sensitive adhesive has good adhesion strength to PET base material, is passed through
The storage of a period of time, the adhesion strength between PET base material and rubber pressure-sensitive adhesive still still can weaken significantly, and then cause
By adhesive tape from be attached removed on article surface when, more or less rubber pressure-sensitive adhesive, which remains in, to be attached on article surface,
Cause to pollute to be fixed or protection the article that is attached, therefore essential solution is obviously unable to using preparatory corona treatment process
The certainly poor problem of adherence of the glue-type pressure sensitive adhesive in PET base material.
A kind of new efficient pressure-sensitive adhesive composition being made of the graft copolymer mutually separated is disclosed at present, it is described
Graft copolymer is by having polymer pendant groups the part such as polystyrene or polyacrylate or poly- (methyl) propylene that are grafted with it
Acid esters main chain composition, is the viscose properties for improving itself using various types of pressure sensitive adhesives that graft polymerization method obtains,
