Abstract

The invention relates to a manufacturing method of a green and environment-friendly solid wood multilayer decorative board, and belongs to the technical field of heat preservation decorative board forming technology. The manufacturing method comprises the following five steps that 1, materials are mixed; 2, the mixed materials are put in an extruder to being extruded; 3, shaping is carried out; 4,bonding is carried out; and 5, cutting and packaging are carried out. According to the manufacturing method, the process conditions are relatively mild, and continuous production can be realized; anda bottom layer uses cheap PP and PE as a waterproof and moisture-proof layer, the cost is reduced, and the reinforcing effect of wood fibers enables a board to be not prone to cracking. The bonding performance of a flame-retardant decorative board prepared by the manufacturing method meets the requirements of national standards, and base materials have flame retardant performance; moreover, the mechanical properties of the base materials are not affected, the formaldehyde emission is further above E1 level, and safety and environmental protection are achieved; and at the same time, the natural texture of wood is maintained, and the decorative effect is good.

Description

technical field [0001] The invention relates to a flame-retardant decorative board, a preparation method thereof and a flame-retardant material comprising the flame-resistant decorative board. Background technique [0002] Expanded polystyrene (EPS) has the advantages of low density, high specific strength, low water absorption, acid and alkali resistance, good heat and sound insulation, good thermal insulation, shockproof, decorative, easy to form, and excellent cost performance, making it It has been developed rapidly. In addition to being widely used in cushioning packaging, food preservation packaging, interior and exterior wall insulation, heat insulation, etc., it has also become more and more eye-catching in the construction and industrial fields in recent years. The outstanding contribution of EPS in architectural applications lies in its thermal insulation and thermal insulation properties. Its extensive use in buildings can effectively reduce the use of air conditi...
