The invention provides a special environment-friendly paint prepared by using a raw lacquer as a biomass base for furniture and cabinets and aims at providing a furniture and cabinet paint which is mainly prepared from raw lacquer, is environment-friendly and has excellent ecological properties. The environment-friendly paint comprises components such as the raw lacquer, a filler, a diluent and auxiliaries; the environment-friendly paint is technically characterized in that every 100 parts of raw lacquer is blended with 0.5-10 parts of magnesium salt whiskers. The high temperature resistance and the oil resistance of the raw lacquer for a cabinet are remarkably improved; when a traditional raw lacquer is applied to a cabinet tabletop, the high temperature requirement of the traditional raw lacquer hardly reaches the special heat resistance requirement of the cabinet tabletop, and the modern chemical paint cannot be comparable with the traditional raw lacquer in term of the heat resistance; consequently, the modern cabinet tabletops are seldom coated with the paint. The special environment-friendly paint completely overcomes the shortcoming; especially, as the paint is added with basic magnesium sulfate whiskers are added to the special environment-friendly paint, the heat resistance of the paint is obviously improved, and the comprehensive cost caused by use of the basic magnesium sulfate whiskers is not higher than the cost caused by use of the raw lacquer according to the traditional technology.
