摘要： PURPOSE:To obtain a block of a powdered rubber composition, by a method wherein the title mold is constituted of a flat-platelike bottom force and top force, which is provided with an intermediate mold at a fixed height on the fringe part and has a recessed section, and the tip part of the intermediate mold coming into contact with the bottom force is formed into an acute-angled state. CONSTITUTION:A molding and curing mold 10 is constituted of a flat-platelike bottom force 11 and top force 13, which is provided with an intermediate mold 12 at a fixed height on the fringe part and has a recessed section. The tip part 12a of the intermediate mold 12 is formed into an acute-angled state and at the time of molding, a powdered rubber composition Q is torn off between the top of the bottom force 11 and intermediate mold 12. The tip part 12a is constituted of the quality of the material whose hardness is higher than that of the bottom force 11 so that the tip part 12a is not damaged when the same is caused to abut against the top of the bottom force 11. The powdered rubber composition Q is cast onto the flat-platelike bottom force 11, rolled by a leveling bar 14 or a rolling roller 15 and formed into a fixed thickness. The top force 13 is put vertically over the same from the upper part, fixed pressure is applied to the same by a press machine and when the tip part 12a of the intermediate mold 12 abuts against the top of the bottom force 11, the powdered rubber composition Q is torn off by the acute-angled tip part 12a. The powdered rubber composition Q is cured by heating and pressurizing the same and molded into a blocklike state.

摘要： PURPOSE:To provide a swellable adhesive comprising a non-cured adhesive and a swellable material, facilitating the simultaneous assembling of plural members, filling up clearances between the members with the swollen adhesive when the adhesive is cured, and giving a good adhesive strength when the plural members are simultaneously assembled with each other. CONSTITUTION:The swellable adhesive is produced by mixing (A) 100 pts.wt. of a liquid or viscous semi-solid non-cured adhesive (e.g. an epoxy resin, an urethane resin or their filmy or sheet-like article) with (B) 7-8 pts.wt. of a swellable material (e.g. 'EXPANCEL(R)': the powder of swellable fine particles manufactured by Japan Ferrite Co. etc.,), or by scattering or coating the component B on the surfaces of the component A. For example, when two kinds of pipes, e.g. a pipe 1 produced from a glass fiber-reinforced epoxy resin prepreg and a stainless steel pipe 2, are fit to each other and subsequently bonded, the pipes are fit to each other in the state that the adhesive 3 is coated or wound on the adhering surface of the member, and the adhesive is subsequently thermally cured to slightly swell, thereby filling up the clearances between the members with the swollen adhesive to strongly bond the pipes to each other.

摘要： PURPOSE:To obtain the title adhesive excellent in ordinary state adhesiveness, heat-resistant adhesiveness and water-resistant adhesiveness by mixing a polyol component comprising a mixture of two specified polyols with a specified isocyanate component. CONSTITUTION:The title two-pack adhesive is obtained by mixing a polyol component (A) comprising a mixture of a polyol (a) of a hydroxyl value of 380-620, prepared by addition-polymerizing propylene oxide with pentaerythritol, with a polyol (b) of a hydroxyl value of 190-325, prepared by addition- polymerizing propylene oxide with 2,2'-bis(4-hydroxyphenyl)propane, with a normally liquid isocyanate component (B) of an average functionality >=2 comprising polymethylene polyphenyl isocyanate and/or carbodiimide-modified 4,4'- diphenylmethane diisocyanate. Because this adhesive is cold-setting, one, it excels in dimensional stability and causes no warpage when applied to a structural laminate unlike heat-setting one.
