摘要:
A white board comprises a front surface layer composed of a polyester film having undergone a hard coat treatment and a rear surface layer composed of a sheet-like magnet. The white board can be easily attached to and detached from steel walls, glass plates, etc. and stored in a rolled state when not in use.
摘要:
An impact-resisting anti-lacerative window glass unit or laminate of a sandwich structure is disclosed, which comprises two exterior plate-like member made of a transparent organic polymer (A) and a transparent organic polymer (B) or a transparent inorganic material, respectively, and multilayer structure intermediate films made of at least two kinds of polymers (C). The multilayer structure intermediate films are interposed between two exterior plate-like members. A method of fitting such an impact-resistsing anti-lacerative laminate to a window frame or an automobile is also disclosed, which comprises removing a fitting portion of a hard coated transparent organic polymer (A) and the multilayer structure intermediate films through peeling while remaining at least one layer of a high breaking strength material layer as one of at least two kinds of the polymers (C) in the multilayer structure intermediate films on a person's side, and fitting the laminate to the window frame or an automobile body with an adhesive sealant by utilizing a thus exposed surface.
摘要:
A vulcanized rubber composition containing at least 30% by weight, based on the amount of the rubber component, of syndiotactic-1,2-polybutadiene has a high adhesion, and can be easily and firmly adhered to another vulcanized rubber composition or to a porous material through a syndiotactic-1,2-polybutadiene thin film by a hot-melt adhesion process.
摘要:
A sandwich structure having an improved impact resistance comprises two outer plates and an intermediate layer interposed therebetween. The intermediate layer is comprised of plural films having a bonding force therebetween lower than that between intermediate layer and outer plate.
摘要:
An adhesive composition which shows improved stickiness and adhesive property at room temperature and exhibits an excellent adhering ability in a short time is prepared by compounding(a) an acrylonitrile-containing copolymer having carbon-to-carbon double bond(b) a phenol-polysulfide resin(c) a metal oxide, and(d) a polyfunctional electrophilic reactive compound containing at least two electrophilic reactive groups.
摘要:
A viscous rubber composition consisting mainly of a non-polar rubber, polybutene and white carbon has high adhesion and excellent puncture-sealing properties. Pneumatic tires provided with a puncture-sealing layer formed of such a viscous rubber composition have a high resistance against the puncture due to foreign substances penetrated through the tire.
摘要:
A method for improving the adhering ability of a vulcanized rubber surface by treating said surface with a solution of iodine isocyanate or a mixed solution of iodine isocyanate and iodine to provide a high adhering ability to said surface.The thus treated vulcanized rubber surface can be adhered strongly to other vulcanized rubber or the other various materials by contacting these materials tightly using an adhesive or without using an adhesive.
摘要:
A sandwich glass having excellent safety, durability, scuff resistance and penetration resistance is disclosed, which comprises two glass plates and a laminate interposed therebetween. This laminate consists of at least two intermediate layers composed of a crosslinking type polymer composition, and an organic resin film layer interposed between the intermediate layers.
摘要:
An ion exchanger is produced by reacting a substance containing carbon-to-carbon unsaturated double bond with a solution of iodine isocyanate in an organic solvent and then reacting the resulting isocyanate group added to said substance with a compound having the following formula(X).sub.n R(Y).sub.m or XYwherein X represents an addition active group to the isocyanate group, Y represents an ion-exchanging group or a chelating group, R represents an organic radical having any valence of from 2 to 6 and a molecular weight of 20 to 1000, and n and m are selected from integers of 1 to 5, respectively, provided that a sum of n and m is equal to the valence of R, to introduce the ion-exchanging group having ion-exchanging properties into said substance.
摘要:
A highly transparent film having high strength, suitable extensibility, high weather resistance, low moisture absorption and so on is disclosed, which consists mainly of EVAT. And also various laminates making the most of the above properties of the film are disclosed, which comprise the EVAT interposed between two inorganic material sheets, two organic material sheets, or an inorganic material sheet and an organic material sheet.
