Description

technical field

[0001] The invention relates to a foaming material and a preparation method thereof, in particular to a fiber-reinforced U-PVC foaming material and a preparation method thereof. Background technique

[0002] Rigid-polyvinyl chloride (U-PVC) has made a major breakthrough in formula and technology after a generation of efforts, endowing the material with excellent performance and making it widely used in the field of building materials. However, due to the inherent characteristics of U-PVC materials, such as large specificity (up to 1.47), too strong plastic texture, and weak shear forces, many properties of wood cannot be achieved by this material. In the past two years, U-PVC foaming materials and wood-plastic materials have been trial-produced, but these materials have defects such as too low strength and easy aging, and their actual use is greatly restricted and cannot replace wood.
