Abstract
Official abstract text for this publication.
There is provided a vehicle lamp which uses a lamp body formed from a resin composition containing a base resin and a plant fiber, wherein a mold which is used to mold the lamp body is not corroded, and wherein if the lamp is manufactured by using the lamp body, fogging or an appearance failure is suppressed from being generated on an inner side of a front cover during usage. A vehicle lamp includes a lamp body which is opened at a front thereof, and a front cover which is attached to the lamp body to close a front opening portion of the lamp body, and the lamp body is formed from a resin composition which contains a base resin, a plant fiber and an acid scavenger.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle lamp including a lamp body which is opened at a front thereof, and a front cover which is attached to the lamp body to close a front opening portion of the lamp body, wherein the lamp body is formed from a resin composition containing a thermoplastic resin, a plant fiber, and an acid scavenger, the acid scavenger is calcium oxide, and the content of the acid scavenger in the lamp body is 0.1 to 5 mass %. 2. The vehicle lamp according to claim 1 , wherein the thermoplastic resin is at least one selected from the group consisting of polypropylene, polyethylene, polylactic acid, polycarbonate, polyethylene terephthalate, polybutylene terephthalate, polystyrene, acrylonitrile-butadien-styrene copolymer, acrylonitrile-styrene-acrylate copolymer, acrylonitrile-ethylene-styrene copolymer, chlorinated polyethylene-acrylonitrile-styrene copolymer, polyamide, polyphenylene sulfide, liquid crystal polymer, and polysulfone. 3. The vehicle lamp according to claim 1 , wherein the plant fiber is at least one selected from the group consisting of pulp, jute hemp, Manila hemp, sisal hemp, ganpi, mitsumata, kozo, cedar, bamboo, cacao, kenaf, banana, pineapple, sugar cane, coconut palm, corn, bagasse, palm, reed, esparto, sabai grass, hemp palm, Musa basjoo, pine, mulberry, agave, wheat, rice, hinoki cypress, cellulose nanofiber, and cellulose fiber. 4. The vehicle lamp according to claim 1 , wherein the content of the acid scavenger in the lamp body is 0.1 to 2 mass %. 5. The vehicle lamp according to claim 1 , wherein the content of the acid scavenger in the lamp body is 0.1 to 1 mass %.
