Foamed wood-plastic composites are based on wood/plastic composites with appropriate amounts of foaming agents, nucleating agents, activators, etc. to reduce the density, improve the impact strength, toughness, fatigue cycle, and thermal stability. . details as follows: 1) The purpose of the foaming agent is to reduce the mass of the composite material (reducing the density), making the application of the composite material more extensive. The foaming agent is decomposed by heating to produce gas, which is incorporated into the composite material and exists in the form of microporous bubbles. Foamed plastic is a bubble composed of bubbles. This experiment mainly used chemical foaming. The foaming agent used was AC. 2) Nucleating agent is a new functional additive. The nanoparticles not only act as nucleation sites for the blowing agent, but also can refine the high polymer grains and increase the toughness of the composite. The nucleating agent used in this experiment is ultra-fine talcum powder. 3) Activator is a reagent that promotes foaming of AC blowing agents at lower temperatures.
