Abstract

The invention belongs to the technical field of building materials, particularly discloses an alkali lignin and polylactic acid resin composite environmentally-friendly plate, and further discloses apreparation method of the alkali lignin and polylactic acid resin composite environmentally-friendly plate. The alkali lignin and polylactic acid resin composite environmentally-friendly plate is formed by hot-pressing and co-extruding a first outer surface layer, a buffer layer, an inner layer and a second outer surface layer which are sequentially stacked, and the first outer surface layer, thebuffer layer, the inner layer and the second outer surface layer are respectively prepared from alkali lignin and polylactic resin particles, powder particles and polylactic resin particles in different proportions. The alkali lignin and the polylactic acid are combined and developed to obtain the novel degradable plate, so that the high-valued utilization of the alkali lignin can be realized, theuse requirements of buildings and home decoration industries can be met, the use amount of wood in building materials can be reduced, and low-carbon, environmentally-friendly and green economy is realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an alkali lignin polylactic acid resin composite environmental protection board, and also relates to a preparation method thereof. Background technique [0002] At present, the boards used in construction mainly include solid wood boards and wood-based panels. Among them, wood-based panels can be divided into solid boards, plywood boards, fiberboards, decorative panels, fireproof boards, particle boards, etc. according to the classification of molding. [0003] Solid wood boards are wood boards made of complete wood. Durable and with a natural grain, these panels are an excellent choice for decoration. However, due to the high cost of this type of board and the high requirements for construction technology, it is not used much in decoration. Except that the floor and door leaves will use solid wood boards, the boards generally used are artificially processed wood-bas...
