Title:
VIBRATION-DAMPING WATER-BASED COATING COMPOSITION
Document Type and Number:
Japanese Patent JP3827031
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a vibration-damping water-based coating composition that does not need any vibration-proofing sheet, can dispense with a complicated templating work and can be applied to vertical or ceiling parts of automotive cabin, by using a vinyl acetate resin emulsion having a specified Tg, specified gel fraction and a specified loss angle tangent and a filler, as the essential components.
SOLUTION: This composition essentially consists of a vinyl acetate resin emulsion having an average particle diameter of 150-1,000nm and obtained by emulsion-polymerizing a mixture based on vinyl acetate and a (meth)acrylic ester in the presence of an emulsifier in an aqueous medium and 20-79vol.%, based on the solid matter of the composition, filler. The vinyl acetate resin should have a Tg of 10-50°C, a gel fraction of 0-30% (as measured in methanol) and a loss angle tangent (tan δ) of 1.5 or above. The amount of the filler used is 20-70vol.% based on the solid matter of the composition.
