Description
The present invention relates to pressure sensitive adhesive (PSA) field.
The application of PSA is that protective membrane is covered on the responsive surface (for example glass of mobile telephone or LCD display panel).
It is very important that PSA can easily remove (even aging back) from these extremely sensitive display surfaces.At first PSA is coated onto on the film (for example PET), applies it to sensing surface with low-down contact force then.Therefore for this purposes, people wish PSA can be in the several seconds wetting these surfaces do not have the coating in visual slit with formation.These PSA not necessarily contain adding antistatic filler wherein to avoid the accumulation of static charge.
Removable PSA in the past utilizes the combining so that it can be removed of acrylic acid series PSA of polyisocyanates and hydroxyl-functional.Yet these tackiness agent wetting speeds are too slow.
JP 2001-131513-A (Ipposha Oil) has described the method for a kind of blend polyether polyol and polyisocyanates.The reaction of this blend forms the polyether polyols with reduced unsaturation with isocyanide ester functional group, then with the acrylic acid series PSA blend with hydroxy functional group to obtain removable PSA.The shortcoming of this method is that preparation PSA needs two steps.

More preferably component I comprises at least two kinds of monomeric multipolymers, and described monomer is selected from ethyl acrylate (EHA), n-butyl acrylate (BA), Hydroxyethyl acrylate (HEA) and hydroxyethyl methylacrylate (HEMA).
Advantageously, the content of component I I (polyhydric alcohol polymer) in composition is counted about 10%-about 30% with the gross weight of component I and II.
The preferred polyvalent alcohol that constitutes component I I can comprise following structure division: polypropylene glycol (PPG); Polyoxyethylene glycol (PEG); Hydroxyl-functional siloxanes and/or hydroxyl-functional polyester and their multipolymer.More preferably component I I comprises PPG and/or PEG.
Aptly, the polyvalent alcohol molecular weight is about 200-10, and 000 dalton is preferably from about 2, about 3,000 dalton of 000-.Favourable polyvalent alcohol is to form those of clear saturating cast film when being PSA and polyfunctional isocyanate's (for example component III) blend with solvent-type acrylic.
Advantageously, the content of component III (polyfunctional isocyanate) in composition is counted about 2%-about 10% with the gross weight of component I and II.
Preferred one or more isocyanate-monomers comprise at least two suitable functional groups, for example aromatic isocyanate (for example TDI, MIDI and/or XDI), aliphatic isocyanate (for example: HDI, IPDI and/or HMDI) and derived from these one or more monomeric one or more polymkeric substance (for example PAPI, prepolymer and urea oligopolymer).
Advantageously, one or more isocyanate-monomers with component (I) and (II) can form clear saturating cast film during blend.One or more more favourable isocyanic ester are to have permanent, good storage period thereby help those of coating.Form film by tackiness agent from the shifting process in the isolation liner.Therefore can before forming film, keep the functional group of PSA and can not produce the problem that is affixed to (film coalescence) on the film.
