Abstract

The invention provides a heat and sound insulation wood plastic material, belonging to the technical field of decorative wood plastic material. The material is composed of 80-100 parts of wood fibre, 20-35 parts of polyurethane plastic, 1-3 parts of a foaming agent, 3-5 parts of a plasticizer, 1-3 parts of fire retardant, 1-2 parts of an anti-oxidant, 1-2 parts of a flexibilizer and 0.5-1 part of a dispersant. According to the invention, the raw materials are easily available and cheap; and the prepared sheet materials has excellent performances of fire resistance, water resistance, corrosion resistance, humidity resistance, insect resistance, fungi resistance, acid and alkali resistance, no toxicity and no pollution; has higher hardness, longer life and higher strength than plastics do; and uses urethane foam, thereby not only being good in the heat insulation effect, but also having the sound insulation effect. The material can be used for decorating metope and base plate, and being made into furniture at the same time, and is beautiful and durable.

Description

technical field [0001] The invention relates to a heat-insulating and sound-insulating wood-plastic material, which belongs to the technical field of decorative wood-plastic materials. Background technique [0002] With the improvement of people's living standards, the requirements for the quality of life are also getting higher and higher, especially for the living environment, not only for comfort and practicality, but also for environmental protection and beautiful performance. At present, factories are blooming everywhere, and many factories are built very close to residential buildings, so the operation of the machines in the factories will affect the lives of residents. In addition, with the increase of private vehicles, the movement of vehicles on the road has become more and more louder and louder, which affects the normal life and rest of the people. In response to the impact of noise, there have been many sound insulation materials. The more common sound insulatio...
