摘要： PURPOSE:To obtain the title tape improved in parting from calender rolls, heat resistance, etc., and prevented from undergoing telescopic side sticking by coating a plastic film support with a pressure-sensitive rubber adhesive layer comprising a mixture of an uncrosslinked rubber with a crosslinked rubber. CONSTITUTION:A mixture is obtained from 100 pts.wt. uncrosslinked rubber such as natural rubber or butyl rubber, 5-100 pts.wt. crosslinked rubber such as, desirably, butyl rubber and, optionally, about 20-100 pts.wt. softener such as a process oil and about 40-300 pts.wt. filler such as white carbon. A plastic film support such as a PE film of a thickness of about 0.05-0.25mm is coated with said mixture as a pressure-sensitive rubber adhesive layer in a coating thickness of about 0.1-3mm. It is preferable that said butyl rubber has a gel fraction of about 40-90% and that said filler has a particle diameter of about 5nm-20mum.

摘要： PURPOSE:To remove a narrow joint so as to facilitate execution and to eliminate the need of repairing a joint part by providing joints on the outer peripheries of two adjacent sides of a tile mould, and providing no joint on the outer peripheries of the remaining two sides. CONSTITUTION:In a tile mould formed by a sheet where a pressure sensitive adhesive is applied to one surface thereof, joints 1, 2 are provided on the outer peripheries of the adjacent two sides, and there is no joint on the outer peripheries of the remaining two sides. Further, Rs are provided on the forward ends of the joints 1, 2 of mutually crossing sides where there is no joint. First, the mould is stuck to the bed, and then the side having joints 1, 2 of the next mould is stuck to the side having no joint of the previously stuck mould. This execution is repeated. Thus, there is no joint in a narrow part, so that the work can be facilitated and it is possible to overcome such disadvantage that a material enters between joints, resulting in requirement of repair.

摘要： PROBLEM TO BE SOLVED: To reduce material loss and improve the strength of a foam by bonding a plastic or rubber molding to a regular form sealing material which is molded with a self-fusion-bonding rubber compound into a shape to be bonded to the molding. SOLUTION: A plastic or vulcanized rubber cover is made by injection molding, press molding, etc., while a regular form sealing material 4 is made from self-fusion-bonding rubber, and the cover and the sealing material 4 are combined into a composite. A cover main body is molded by injection molding, compression molding, vacuum forming, etc., with the use of plastic such as polyethylene, polypropylene, and nylon 6 or rubber such as chloroprene, ethylene- propylene rubber, and butyl rubber. A rubber compound in which a rubber component is mixed with a filler, a tackifier, a softening agent, etc., is used as the self-fusion-bonding rubber 2. Since the molding of the rubber 2 is bonded afterward to a plastic molding or a vulcanized rubber molding which has been difficult in working into a composite, working is made possible.

摘要： PURPOSE:To form a passive film on a metallic surface by incorporating a material for passivating the metallic surface into an aq. gel of a specific polymer and bringing the gel into contact with the metallic surface. CONSTITUTION:The material for passivating the metallic surface is incorporated into the aq. gel of the polymer having a three-dimensional structure. This gel is brought into contact with the surface of the metal. The material incorporated therein is the hydroxide of alkal metals and alkaline earth metals, the borate, water glass, amine, etc., of the alkal metals and passivates the surface of the metal by dissolving in water. As a result, the coexistence of water and oxygen is no longer of a problem and the infiltration of carbon dioxide is prohibited by the gel.
