Bamboo powder composite material and preparation method and application thereof

Abstract

The invention provides a bamboo powder composite material, which is characterized by comprising the following components in part by weight: 30 to 60 parts of bamboo powder, 40 to 70 parts of melamine resin powder and 3 to 12 parts of hot melt adhesive powder, wherein the ratio of the bamboo powder to the hot melt adhesive powder is 10:1-2. The invention also provides a method for preparing the composite material, which comprises the following steps of: (1) preparing raw materials; (2) pretreating the raw materials; and (3) mixing the pretreated materials. The invention also provides a method for preparing a product of the composite material, which comprises the following steps of: (4) prefabricating a mold; (5) filling the composite material into the mold; (6) performing die casting on the composite material; (7) cooling the die-cast material; and (8) demolding the cooled material. The invention also provides application of the product in the field of manufacturing of sound boxes and the like. The bamboo powder composite material provided by the invention has high bamboo powder content and reasonable preparation process. The product can be particularly applied in specific fields and is in accordance with the concept of waste utilization, environmental friendliness, energy conservation and green production.

Description

technical field [0001] The invention relates to a composite material, in particular to a bamboo powder composite material using bamboo powder and melamine resin, a preparation method and an application thereof. Background technique [0002] Bamboo powder is processed from bamboo fragments, especially the leftovers, leftover waste or by-products (sawdust) of various bamboo products are further crushed and processed. It belongs to waste recycling, and its materials have a wide range of sources and low cost. It is a new type of environmentally friendly and energy-saving filling material that has emerged in recent years. Filling plastic products with bamboo powder will produce special smells such as plant ash, and it can be combined with resin and other polymer materials to obtain many new composite materials. At present, these bamboo powder composite materials have become bamboo plastic products, mosquito coils, leather, clothing, Raw materials for papermaking, electrical appl...
