Definitions
- the present invention relates to a vehicle lamp and particularly to a vehicle lamp that is light and highly strong and that is free from an external appearance failure such as fogging that is generated on an inner side of a front cover that faces an interior of a lamp compartment.
- vehicle lamps have a lamp body that is opened at a front thereof, a front cover that is attached to the lamp body to close the front opening portion, an extension, a reflector, a light source, and electric components.
- a lamp body that is generally formed from a resin material and that occupies a relatively large portion of the total weight of the vehicle lamp.
- Patent Document 1 discloses a technology to obtain a molded part from a resin composition that contains a polypropylene and a vegetable fiber.
- Patent Document 2 is concerned with a composite material comprising resin and fiber, as well as with a molded article obtained from the composite material.
- the fiber may be inorganic fiber, organic fiber, or natural fiber, and as examples glass fiber, carbon fiber, metal fiber, aromatic polyamide fiber, kenaf fiber, bamboo fiber, polyester fiber, nylon fiber, jute fiber, ramie fiber and cellulose fiber are mentioned, with glass fibers being preferred.
- glass fibers being preferred.
- the molded article can be used as automotive plastic part such as exterior parts which are required to have good mechanical strength, durability and appearance.
- a lamp housing is mentioned in this context.
- Patent Document 3 relates to a lighting equipment used for vehicles, a studio lighting equipment, a flashlight and other lighting equipments including a reflector, lens, lamp cover, lamp cap, light guide and other parts.
- the lighting equipment having a reflector and the lens for a lighting equipment comprises a thermoplastic resin containing an alicyclic structure.
- the resin composition containing the thermoplastic resin may additionally contain a compounding agent, which may be a filler.
- a fillers organic fillers and inorganic fillers are mentioned in the document, and wood pulp is given as an example of the organic fillers.
- the document addresses the possibility of treating the fillers on their surface with epoxy silane, amino silane, titanate, aluminum chelate, zircoaluminate, and other silane coupling agents or silicone oil etc. for the purpose of improving the wettability and adhesion between the thermoplastic resin containing an alicyclic structure and filler.
- Patent Document 4 is concerned with flame retardant polyetherimide/polyester-polycarbonate compositions.
- the compositions may comprise reinforcing fillers such as natural fibrous fillers.
- the possibility of surface treating the fillers with silanes to improve adhesion and dispersion with the polymeric matrix resin is mentioned.
- the invention is to provide a vehicle lamp using a lamp body that is formed from a resin composition containing a base resin and a vegetable fiber that is free from an external appearance failure such as fogging that is generated on an inner side of a front cover that faces an interior of a lamp compartment while in use.
- the invention is as follows.
- a vegetable fiber tends to absorb water easily.
- the water contained in the vegetable fiber of the lamp body is emitted therefrom by heat, for example, from a light source, causing fogging inside the lamp compartment.
- the generation of fogging in the lamp compartment can be eliminated by using for the lamp body the vegetable fiber that is surface treated with a fluorine water repellent, a rosin soap, an alkyl ketene dimer, an alkenyl succinic anhydride, a polyvinyl alcohol, or a hydrophobic resin selected from terpene resin, thermoplastic fluorine resin, vinylidene chloride resin and high-density polyethylene.
- Fig. 1 is a schematic sectional view showing an example of a vehicle lamp of the invention.
- FIG. 1 An example of a vehicle lamp of the invention will be described by reference to a schematic sectional view shown in Fig. 1 .

- a spattering method, a vapor deposition method, a plasma CVD, a sol-gel method, a sizing method there are exemplified methods for forming a substance of low moisture permeability on the surface of the vegetable fiber.
- the sizing method is preferable because a water repellent treatment can easily be performed during kneading work.
- the low moisture-permeability substances are hydrophobic resin, fluorine water repellent, rosin soap, alkyl ketene dimer, alkenyl succinic anhydride, and polyvinyl alcohol.
- hydrophobic resin is preferable in consideration of workability, as well as simple and convenient process.
- hydrophobic resins described above there are terpene, thermoplastic fluorine resin, vinylidene chloride, and high-density polyethylene.
- the surface treated vegetable resin used in this embodiment is sized pulp. Sized pulp is preferable because sized pulp contains few impurities that cause the corrosion of a mold that is used to mold the lamp body 3 as described above.
- the content of the surface treated vegetable fiber there is imposed no specific limitation on the content of the surface treated vegetable fiber, and it is preferable to select an appropriate one depending upon the kind of a vegetable fiber to be used or the kind of a base resin, which will be described later, to be used together with.
- a base resin that is used in a resin composition used to mold the lamp body 3 of the invention.
- polypropylene polyethylene
- PE polylactic acid
- PC polycarbonate
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- PS polystyrene
- ABS acrylonitrile-butadien-styrene copolymer
- AS acrylonitrile-styrene-acrylate copolymer
- AES acrylonitrile-ethylene-styrene copolymer
- ACS chlorinated polyethylene-acrylonitrile-styrene copolymer
- PA polyamide
- PPS polyphenylene sulfide
- LCP liquid crystal polymer
- PSU polysulfone
- epoxy resin urethane resin
- silicone resin silicone resin
- PP is preferable.
- kneading should be performed so that at least the base resin and the surface treated vegetable fiber are mixed uniformly.
- the front cover 2 used in this invention is clear and transparent, and therefore, there is imposed no specific limitation on shape and material therefor, as long as the front cover 2 can close the front opening portion of the lamp body 3 so as to define the lamp compartment.
- known shapes and materials can be used.
- materials a clear thermoplastic resin such as polycarbonate, acrylic resin and polystyrene, and a transparent inorganic material such as glass.
- 75 wt% of base resin PP was added to 25 wt% of pulp fiber to which the water repellent treatment had already been applied to adjust the content of pulp fiber to 20 wt%.
- the mixture was kneaded again to obtain PP pellets containing 20 wt% of pulp fiber to which the water repellent treatment had already been applied.
- the pellets obtained were poured into an injection molding machine (EC40N manufactured by Toshiba Machine Co., Ltd.) and were injection molded into a rectangular plate-shaped test piece of 110 mm ⁇ 60 mm ⁇ 3 mm at a cylinder temperature of 190°C and a mold temperature of 40°C.
- Pellets were prepared by the same method as that used in Example 1 except that 20 wt% of pulp fiber and 80 wt% of base resin PP were kneaded.
- test piece of Example 1 could be reduced by about 25% in water absorption as compared with the test piece of Comparative Example 1.
- the generation of fogging in the interior of the lamp compartment can be eliminated by using the surface treated vegetable fiber with a fluorine water repellent, a rosin soap, an alkyl ketene dimer, an alkenyl succinic anhydride, a polyvinyl alcohol, or a hydrophobic resin selected from terpene resin, thermoplastic fluorine resin, vinylidene chloride resin and high-density polyethylene, for the vegetable fiber to be contained in the lamp body, making the lamp so fabricated extremely useful as a vehicle lamp.
- a fluorine water repellent a rosin soap, an alkyl ketene dimer, an alkenyl succinic anhydride, a polyvinyl alcohol, or a hydrophobic resin selected from terpene resin, thermoplastic fluorine resin, vinylidene chloride resin and high-density polyethylene
