The invention discloses a pneumatic polishing reshaping device for a spherical surface and belongs to the field of grinding processing. The pneumatic polishing reshaping device for the spherical surface comprises a pneumatic polisher, a horizontal shaft, a vertical shaft component and an elastic sleeve, wherein the vertical shaft component is hinged with the horizontal shaft through the jaw of a first vertical shaft of the vertical shaft component and is fixedly connected to the elastic sleeve through a second vertical shaft of the vertical shaft component; and the pneumatic polisher is held by the elastic sleeve. When an inner spherical surface of a shell is processed, the horizontal shaft is connected to corresponding positioning holes of the processed shell through first and second endcovers arranged at two ends of the horizontal shaft, the length of an extension rod in the pneumatic polisher is adjusted so as to meet the demand on the radius of the polished spherical surface, andthen ...

The invention discloses a structural pressure-sensitive adhesive, a structural pressure-sensitive adhesive tape and a preparation method of the structural pressure-sensitive adhesive and the structural pressure-sensitive adhesive tape. The structural pressure-sensitive adhesive comprises a constituent A and a constituent B. The constituent A is obtained by polymerizing acrylic acid-2-ethylhexyl ester, butyl acrylate, vinylacetate, methyl methacrylate, acrylic acid, glycerol ester of hydrogenated rosin, dibenzoyl peroxide, ethyl acetate and epoxy resin in a reactor. The constituent A is coatedon a base material to manufacture a pressure-sensitive adhesive tape; the constituent B, which is polyfunctional organic amine epoxy hardener 2,4,6-tri(dimethylamino methyl)phenol, is painted on the surface of a pasted object; the pressure-sensitive adhesive tape is pasted on the surface of the pasted object to form the structural pressure-sensitive adhesive tape. The structural pressure-sensitive adhesive ...
