The present invention provides a polyurethane composite material. In the present invention, ground coffee is added to the polyurethane material, the obtained polyurethane composite material not only meets the mechanical property requirements of the polyurethane material, but also has an excellent adsorption effect. Moreover, because of the moisture absorption and deodorization characteristics of the ground coffee, chemical odor of a polyurethane product can be reduced, and the polyurethane material has the fragrance of coffee. The prepared polyurethane material has a strong adsorption function and can be used for removing foreign odor, so that the space using the polyurethane product is fresher, and the effect of purifying the environment is achieved. |
