摘要:
A fiber material for reinforcing plastics prepared by laminating at least one first fiber substrate in which the reinforcing fibers extend in two directions including the longitudinal direction and the transverse direction intersecting therewith at a substantially right angle with at least one second fiber substrate in which the reinforcing fibers extend in two directions including directions having angles of .+-.(25-65) degree relative to the longitudinal direction. Or, a fiber material for reinforcing plastics prepared by laminating at least one first fiber substrate in which the reinforcing fibers extend in at least one of two directions including the longitudinal direction and the transverse direction intersecting therewith at a substantially right angle, at least one second fiber substrate in which the reinforcing fibers extend in a direction having an angle of (25-65) degree relative to the longitudinal direction and at least one third fiber substrate in which the reinforcing fibers extend in a direction having an angle of -(25-65) degree relative to the longitudinal direction. The above laminate moldings are integrated with each other by stitch yarns passing repeatedly in the direction of lamination.
摘要:
A polyacetal resin composition excellent in heat stability and surface processability which comprises (a) about 100 parts by weight of polyacetal resin, (b) about 2 to about 35 parts by weight of a carbonate, phosphate or acetate of a metal belonging to Group II of the Periodic Table or a mixture thereof and (c) about 0.01 to about 20 parts by weight of a polymer, a copolymer or a mixture thereof of a compound selected from the group consisting of unsaturated polyesters, alkyl esters of acrylic acid or methacrylic acid, amides of acrylic acid or methacrylic acid, triallyl cyanurate, diallyl phthalate, vinyl acetate and divinylbenzene.
摘要:
The present invention relates to a cushioning composite molded article obtained by forming a cushioning material having a surface material on a rigid substrate integrally, and a process for producing the composite molded article by a simple procedure involving a small number of steps for production, and when a rigid-resin molded product is set in a mold and an expandable elastomer is injected, after which the inside of the mold is enlarged to expand the substance, the expanded elastomer becomes a cushioning material and its skin layer becomes a surface material, and the formation of them and the union in a body of them and the rigid substrate, i.e., the rigid-resin molded product can be carried out in one mold in succession, so that the production is easy and that labor and the production cost are saved.
摘要:
To prevent the growth of aquatic animals and plants on the surfaces of underwater structures, the surfaces are covered with a protective adhesive sheet comprised of a copper-nickel alloy plate having a weight ratio of copper:nickel in the range of 100:0 to 80:20, a primer layer formed on the alloy plate, and a pressure-sensitive adhesive layer formed on the primer layer. Prior to applied the adhesive sheet, the surface to be protected is preferably cleaned and coated with a primer of the same composition as that of the primer layer of the adhesive sheet.
摘要:
This invention relates to a resin composition comprising an oil retainer, a base thermoplastic resin and an oil. The affinity of the oil retainer and base resin to the oil is defined to result in a resin composition which is excellent in moldability, lubricity and surface appearance.
