Definitions
- No. 3 proposes the use of urethane resin mainly containing nylon reinforcing nets. Since the cover for the airbag device as described above uses a nylon-based net for reinforcement, the part of the recovery that has cracked other than the cracked part during deployment may scatter. The problem has been solved. However, it takes time to incorporate the reinforcing net when molding the cover. However, there is a problem that the position of the reinforcing net is displaced, and the productivity is inferior.
- Some additives are not added, and some are added at a low ratio, and have excellent flexibility, weather resistance, heat resistance, low-temperature properties, strength, moldability, and improved scratch resistance.
- the inventors have found that a stoma composition can be obtained, and have completed the present invention.
- the main object of the present invention is to provide a thermoplastic elastomer having excellent flexibility, heat resistance, low temperature properties, weather resistance, strength, moldability, and scratch resistance of the molded product surface.
- One composition is provided.
- Another object of the present invention is to provide a molded article obtained by molding the above-mentioned thermoplastic elastomer composition, and to provide the above-mentioned excellent various properties possessed by the thermoplastic elastomer composition itself.
- An object of the present invention is to provide a cover for an airbag device which is excellent in deployability in addition to the features, and which holds the airbag device in an openable manner.
- polystyrene resin examples include an ethylene polymer resin and a propylene polymer resin.
- ethylene polymer resin examples include branched low-density polyethylene, linear low-density polyethylene, high-density polyethylene, ethylene and ⁇ having 3 to 8 carbon atoms.
- Copolymers with olefins These can be used alone or in combination May be.
- haloolefins in copolymers of ethylene and ⁇ -olefins having 3 to 8 carbon atoms examples include propylene,
- the hydrocarbon oil blended in addition to the components (a) and (b) is selected from the group consisting of: It has the effect of improving moldability, and includes, for example, non-aromatic mineral oils or liquids or low molecular weight synthetic softeners.
- non-aromatic mineral oil generally known paraffinic oil and naphthenic oil can be used.
- a non-aromatic mineral oil mixed with an aromatic component may be used, but in this case, a paraffinic oil having an aromatic component of 10% by weight or less is preferable.
- a No. 3 dumbbell was cut out from a 2 mm-thick press sheet as a sample, and measured with JIS K6301.
- a flat plate with a smooth surface was formed by injection molding.
- the flat plate was spread horizontally, and a cotton cloth with a load of 40 g Z cm 2 was placed thereon, and the plate was reciprocated 10 times.
- the glossiness of the friction surface was measured by the method of JISK 7105 (E1), and the gloss retention ratio from the glossiness (E0) before friction; (ElZEO) XI00 (%) was obtained.
- E1 JISK 7105
- a styrene Z butadiene block copolymer having a structure of B—A—B—A is hydrogenated, Number average molecular weight 69,000, molecular weight distribution 1.2, bound styrene before hydrogenation 40% by weight, hydrogenation rate of polystyrene part 1% or less, polystyrene before hydrogenation
- a hydrogenated block copolymer having a 1,2-butulyl bond content of 36% by weight in the butadiene portion and a hydrogenation rate of 9.9% in the polybutadiene portion was obtained.
- Asahi Polipro E710 (MFR 0.5 g / 10 minutes, Japan, Asahi Kasei Kogyo).
