METHOD FOR MANUFACTURING FOAM TAPE FOR AUTOMOBILE AND FOAM TAPE COMPOSITION FOR AUTOMOBILE

摘要

The present invention relates to a method for manufacturing a foam tape for an automobile including an acrylic monomer, a photoinitiator, a crosslinking agent, and a foaming agent, comprising: (a) preparing a low viscosity syrup by UV polymerization of an acrylic monomer; (b) preparing a foam composition for automobiles to which a photoinitiator, a crosslinking agent, and a blowing agent represented by the following Formula 1 are added to the low viscosity syrup prepared in the step; And (c) manufacturing the foam tape for automobiles by UV curing after coating the composition. [Formula 1] According to the present invention, it is applied to curved surfaces such as body side molding, bumper molding, window molding, emblem, door edge molding, pad protector, mud guard, side visor of automobile exterior parts, and excellent adhesive properties and flexibility such as high adhesive strength and cleavage characteristics. It is possible to provide a foam tape composition for automobiles which can be directly adhered without pretreatment such as a primer in order to apply to a method of manufacturing a foam tape for automobiles having a coating surface of an automobile exterior part.
