摘要:
Highly acoustical auto ceiling panel characterized in that polyethylene foams are laminated with a metal lath sandwiched between them; the surface of the interior side polyethylene foam is coated with a vinyl chloride sheet and this foam with said sheet is provided with numerous small holes through two layer, while the other polyethylene foam across said metal lath is provided with numerous through holes of a diameter larger than that of the hole in the former foam; and the manufacturing process of this auto ceiling panel.
摘要:
Auto ceiling panel with an improved sound-absorbing effect which is obtained by thermally fusing a polyethylene foam with numerous small holes and another polyethylene foam with numerous large holes with a metal lath sandwiched between them; and its manufacturing method.
摘要:
An auto ceiling panel takes the form of a laminate composed of a permeable ceiling surface skin, a first layer of porous continuous bubble plastic foam attached to the skin, a second foamed plastic layer with numerous through holes attached to the first layer, and a third foamed plastic layer with through holes of a larger diameter than the holes in the second layer. A metal lath is between the second and third layers, and the second and third layers are fused to the metal lath.
摘要:
An automotive ceiling panel and a process for manufacturing same, in which one surface of a first polyethylene foam layer is embossed to form a crimp pattern thereon, a metal lath is sandwiched between the first polyethylene layer and a second polyethylene layer, then the three layers thus placed are introduced between rollers for fusion-bonding and rolling, and a laminate thus prepared is cold-pressed into a desired shape for a ceiling. This automotive ceiling panel consists of three layers, rather than four layers as in the prior art ceiling panels, thus saving its weight and man hours required for manufacture to a great extent, yet providing high quality.
摘要:
A shock absorbing bumper adaptable for mounting onto the front and rear of a vehicle such as an automobile, the bumper comprising an elastic external member having sheathed therein a flexible core material and a decorative facing provided on the front side of the external member. An elastic facing base having formed on its front side the elastic decorative facing is provided on its rear side with a hook or hooks which fit into the corresponding slits formed in the front portion of the external member and are engaged therein in such a way that they overhang the edges of the slits while the rims of the facing base fit in the lateral notches also formed in the external member.
摘要:
A shock absorbing bumper adapted for mounting on the front and rear ends of a vehicle such as an automobile, comprising an elastic external guard member having sheathed therein a shock absorbing flexible core member and a separately molded elastic decorative facing base provided on the front surface of the external guard member. The elastic facing base is integrally secured to a horizontal recession in the surface of the external guard member by inserting claws at both edges of the facing base into the corresponding holes formed along both upper and lower edges of the recession.
摘要:
This invention relates to vinyl chloride resin composition suitable for automobile interior skin material of which the die pollution is low, die releasing capacity is light and amine resistance is high.This invention provides the vinyl chloride resin composition for powder material forming characterized by the components of the mixture consisting of: 100 parts for weight of vinyl chloride resin, 0.01 to 3 parts for weight of the thermal stabilizer indicated by general formula (RCO0).sub.2 M(in the formula, R: alkyl group having 10 to 20 carbons, M: lead, zinc, magnesium, calcium, cadmium, strontium or barium), 0.01 to 5 parts for weight of hydroxy stearic acid and/or hydroxy stearic acid dister polymer, and plasticizer.
摘要:
Auto parts prepared from polyurethane are manufactured by a process comprising:(a) preparing a polyol component by blending a stabilizer combination of (A) nickel dibutyldithio carbamate with (B) N-mono- or dimethylphenyl-N'-mono- or dimethylphenylphenylenediamine and/or (C) N,N'-diphenyl-p-phenylenediamine with a polyol and carbon black;(b) reacting said polyol component with a polyisocyanate: and(c) molding said reacted mass.
摘要:
Elastic metallized decorative moldings are disclosed composed of a modified polyurethane resin as a substrate coated on the surface thereof with a metallized layer, the polyurethane resin comprising 50-95 parts by weight of a thermoplastic polyurethane resin incorporated with 5-50 parts by weight of an acrylonitrile-butadiene-styrene resin comprised of at least 75% by weight of an acrylonitrile-styrene component and not more than 25% by weight of a butadiene component. Such elastic metallized decorative moldings are useful as impact-absorbing materials with beautiful appearance for various structures, especially as bumper moldings for motor vehicles.
摘要:
This invention provides polypropylene resin compositions which have sharply improved balance of physical properties in comparison with the related polypropylene materials, are materials that can be used in both interior and exterior parts of automobiles, have excellent thin-wall moldability and can sharply reduce generation of flow marks. Particularly, it provides a polypropylene resin composition which comprises specified amounts of (A) a specified ethylene-propylene block copolymer, (B) a specified thermoplastic elastomer and (C) talc, wherein it has specified values of physical properties measured by ASTM and has a degree of b-axis orientation of 720 or more which is calculated from the ratio of differential peak intensities measured by wide-angle X-ray diffraction of the central area of an ASTM No. 1 dumbbell prepared by injection molding.
