Abstract

PURPOSE:To provide the titled adhesive compsn. having moderate bonding strength and capable of re-bonding, by a process wherein a mixture of particular esters and a functional group-contg. ethylenically unsatd. compd. are blended in an aq. soln. of water-soluble high = molecular materials and the blend is polymerized by the addn. of a polymn. initiator. CONSTITUTION:The titled compsn. is yielded by blending a mixture of 6-12C alkyl (meth)acrylates with 5C or lower alkyl (meth)acrylates and a functional group-contg. ethylenically, unsatd. compd. (e.g., epoxy group-, carboxyl group-, or amide group = contg. ethylenically unsatd. compds.) in an aq. soln. of water- soluble high-molecular material (e.g., PVA) and polymerizing the blend by the addn. of a polymn. initiator. Said compsn. has moderate bonding strength and is capable of re-bonding even it has been peeled from the surface of objects to be protected; for instance, it is possible that an adhesive is applied to paper such as Kraft paper and the film of said compsn. is activated by steam, etc., and thereafter the adhesive is put on the surface of objects to be protected for application.

As mentioned above, the adhesive composition for surface protection materials according to the invention uses an aqueous solution of a water-soluble polymer substance,
Examples of water-soluble polymeric substances include polyvinyl alcohol, methylcellulose, caloxymethylcellulose, ethylene-vinyl acetate copolymer, and pol+vinyl alcohol is preferably used. Here, the polyvinyl alcohol has a degree of polymerization of 500 to 2,400 and a degree of saponification of 70 to 96 molar, especially one with a degree of polymerization of 1,500 to 200.
0, saponification change of 80 to 90 molt is preferably used. If the degree of polymerization is low, the initial adhesion force will be small and good adhesion to the surface to be adhered will not be obtained, and the solubility in water will be high, and if the adhesive is re-wetted and activated to adhere to the surface to be bonded, The adhesive composition may seep into the substrate for surface protection materials, especially the base paper, and if the degree of polymerization is high, the solubility in water is low, and the viscosity of the obtained water bath liquid is high, making it difficult to process. There are cases where things get worse. Furthermore, if the degree of saponification is too low or too high, rewetting activity tends to be poor.

Furthermore, even if the adhesive composition of the present invention peels off, it can be easily reattached by pressure bonding, so even if the surface protection material is peeled off when inspecting the surface of an object to be protected, it can be easily and completely bonded. In addition, even if the surface protection material should peel off during the bonding process, it can be easily restored by pressure bonding without re-wetting and activation. It can be reattached and mined. Moreover, although the adhesive composition of the present invention maintains good adhesive strength, it can be easily peeled off during peeling, and after peeling, there is a so-called adhesive residue phenomenon and a milky pale (Milky Bale) phenomenon.
) phenomenon is also difficult to occur, and in particular, this type of phenomenon does not occur at all with acrylic resin plates.
