In recent years, wood-plastic composite materials have developed rapidly, and wood-plastic foaming technology is an important technology for wood-plastic composites and has been continuously promoted. Wood-plastic foam composites are developing in a light, environmentally friendly, non-polluting, low-cost direction, and are also a new direction in the research of wood-plastic composites.

The following is a brief introduction to the development of some wood-plastic foaming technology, which can be summarized as the following four points:

1. The microcellular foaming technology is more and more respected. Although the ordinary foaming process reduces the density of the material, the performance of the composite material is lowered, and it is difficult to achieve the purpose of use, and the microcellular foaming solves this well. The small bubbles produced by the microcellular foaming can diffuse the cracks, do not spread along the original cracks, passivate the cracks intermittently, and the performance is obviously improved. Microcellular foaming not only reduces density but also improves mechanical strength and machinability.

2. Responsible for the more mature additives, the use of non-polluting foaming auxiliaries can effectively solve the problem of “white pollution”, and the environmental pollution caused by the burning of straw and waste wood is also alleviated. The most important thing is that wood-plastic composite materials can be repeated. Reuse, easy to break down. Many scholars have studied the use of water instead of foaming agents to foam while trying to use the volatiles in the wood powder, the moisture carried to foam.

3, the new attempt of foaming the emergence of foaming masterbatch, mainly to solve the problems of chemical foaming hair. For example, the foaming agent is generally powdery and difficult to measure, and the composite foaming agent can be developed, which provides convenience for injection foaming and improves the quality of injection foaming. Many scholars in China have invented a masterbatch similar to a carrier. This functional masterbatch can be uniformly mixed with wood-plastic composite materials, effectively solving the defects of uneven foaming, uneven cell and fusion of cell rupture, and at the same time Production costs are reduced, power consumption is reduced, and products of reliable quality can be obtained under simple process conditions.

4. The introduction of computer simulation technology With the rapid development of the technology field, the simulation of computer technology has also been applied to the design of composite materials (foaming), which has become a means to quickly obtain the performance index of materials.
