Abstract

The invention relates to an unsaturated polyester resin composite material for furniture. The composite material is characterized by comprising the following components in parts by weight: 100 parts of unsaturated polyester resin, 20 to 40 parts of modified bamboo fibers, 20 to 50 parts of flame retardant, 0.5 to 3 parts of accelerant, 0.8 to 2 parts of initiating agent, 0.5 to 2 parts of defoaming agent and 1 to 10 parts of coupling agent. The invention further provides a preparation method of the unsaturated polyester resin composite material for furniture. The composite material is good in overall mechanical property and flame retardant property as well as excellent in comprehensive property, and can be used for replacing log materials and can be directly molded in a room-temperature curing manner. Thus, the composite material is simple to prepare and easy for scale production, and meets the modern environmental friendliness requirement. As a result, the composite material provided by the invention is especially suitable for the mass manufacturing of the furniture, especially classical furniture.

Description

technical field [0001] The invention relates to a polymer compound composition, in particular to an unsaturated polyester resin composite material for furniture and a preparation method thereof. Background technique [0002] In the furniture industry, especially in the classical furniture industry, raw wood is the most used material. Whether it is European style or Chinese classical furniture, the raw materials are generally solid wood, such as elm, nanmu, camphor and so on. The extensive use of log materials has led to large-scale felling of forests and caused environmental damage. Therefore, how to reduce the use of log materials to protect environmental resources more effectively has become a problem that furniture manufacturers should and must consider. Moreover, the carving process in classical furniture is an art of carving and decorating wooden furniture objects with sharp hand tools. This kind of carving process is mainly done by hand carving, which is labor-intensi...
