Embodiment 1

[0057] Mix 72 parts by weight of 2-ethylhexyl acrylate, 4 parts by weight of N,N-dimethylacrylamide, 24 parts by weight of isobornyl acrylate, and 0.04 parts by weight of 1,6-hexanediol dimethyl acrylate, and 0.04 parts by weight of a photopolymerization initiator (Irgacure 651, BASF Japan (BASF Japan)). Use 0.5mW / cm 2 The resulting mixture was irradiated with ultraviolet rays, and the irradiation was completed when the viscosity of the mixture reached 1000 cps. To the mixture irradiated with ultraviolet rays, 1.8 parts by weight of acrylic acid, 2 parts by weight of N,N-dimethylacrylamide, 0.4 parts by weight of chlorinated polyolefin (supercron930S, Nippon Paper Industries Co., Ltd. , Ltd.)), 2 parts by weight of tackifier (Arkon P=140, Arakawa Chemical Industries, Ltd. (Arakawa Chemical Industries, Ltd.)), photopolymerization initiator (Irgacure 651), 1.5 parts by weight of fine carbon dioxide Silicon particles (A200, Nippon Aerosil Co., Ltd.), and 6 parts by weight of fi...

Abstract

The invention discloses a pressure sensitive adhesive article and a method of reinforcing a vehicular member. The pressure sensitive adhesive article of the present invention includes a pressure sensitive adhesive layer comprising a pressure sensitive acrylic polymer and inorganic fine particles. The pressure sensitive adhesive article also includes a fibrous sheet formed by a plurality of mutually intersected fibers that are arranged in the pressure sensitive adhesive layer.

Description

technical field [0001] The present invention relates to a pressure-sensitive adhesive article, and more particularly to such an article comprising a pressure-sensitive adhesive polymer with fine inorganic particles and fibrous sheets in the pressure-sensitive adhesive polymer. The invention also relates to methods of reinforcing vehicle components with pressure sensitive adhesive articles. Background technique [0002] In recent years, vehicle exterior members such as bumpers and interior members formed by injection molding need to be thinned for the purpose of weight reduction. On the other hand, strength is also required for vehicle components, so it is important to achieve thinning and secure strength. However, with injection molding, if insufficient strength of a vehicle member is detected after mold design or molding, the mold itself must be corrected, and this consumes labor and time. [0003] On the other hand, in order to reinforce the bumper, a bumper reinforcemen...
