Abstract
Official abstract text for this publication.
Provided is a UV curable sealing material containing a vinyl chloride sol as a main ingredient, the film strength of the sealing material being not reduced even in a thin film, the sealing material thus having high resistant pressure against a hem blister. Provided is a vinyl chloride sol composition containing a vinyl chloride-based resin, a UV curable resin having a polar group (functional group), a blocked isocyanate resin, and a filler, the vinyl chloride sol composition being characterized by containing the UV curable resin having a polar group (functional group) in an amount of 20 to 100 parts by weight, the blocked isocyanate resin in an amount of 10 to 50 parts by weight, and the filler in an amount of 50 to 160 parts by weight, relative to 100 parts by weight of the vinyl chloride-based resin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vinyl chloride sol composition comprising a vinyl chloride-based resin, a UV curable resin having a polar functional group, a blocked isocyanate resin, and a filler comprising a non-hydrophobically surface-treated silica and a hydrophobically surface-treated silica, the hydrophobically surface-treated silica in an amount of greater than 0 to 100 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin, the vinyl chloride sol composition containing the UV curable resin having a polar functional group in an amount of 20 to 100 parts by weight, the blocked isocyanate resin in an amount of 10 to 50 parts by weight, and the filler in an amount of 50 to 160 parts by weight, relative to 100 parts by weight of the vinyl chloride-based resin. 2. The vinyl chloride sol composition according to claim 1 , further comprising a urethane acrylate-based UV curable resin in an amount of 20 to 100 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 3. The vinyl chloride sol composition according to claim 1 , comprising the non-hydrophobically surface-treated silica in an amount of up to 100 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 4. The vinyl chloride sol composition according to claim 1 , comprising, as the filler, in addition to the non-hydrophobically surface-treated silica and the hydrophobically surface-treated silica, a surface-treated calcium carbonate in an amount of 0 to 90 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 5. The vinyl chloride sol composition according to claim 1 , comprising a polymerization initiator in an amount of 0.5 to 10 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 6. The vinyl chloride sol composition according to claim 1 , comprising a latent curing agent in an amount of 0 to 5 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 7. The vinyl chloride sol composition according to claim 1 , comprising, as the vinyl chloride-based resin, two or more vinyl chloride-based resins in mixture. 8. The vinyl chloride sol composition according to claim 1 , comprising, as the blocked isocyanate resin, two or more blocked isocyanate resins in mixture. 9. The vinyl chloride sol composition according to claim 1 , further comprising a polymer-based plasticizer in an amount of 60 to 210 parts by weight relative to 100 parts by weight of the vinyl chloride-based resin. 10. The vinyl chloride sol composition according to claim 9 , comprising, as the polymer-based plasticizer, two or more polymer-based plasticizers in mixture.
