Fibre-reinforced U-PVC foam material and its preparing process

Abstract

The invention relates to a fiber-reinforced U-PVC foaming material and a preparation method thereof, which comprises 60-85% of PVC, 5-20% of flax, 2-10% of non-toxic composite stabilizer, 2-6% of foaming agent and lubricant 2-6%, fully mixed and reacted, then extruded at 100-200°C, cooled and shaped, and then surface treated to obtain the finished product. Compared with the prior art, the present invention has the advantages of light specific gravity, high strength, strong woody feeling, wear resistance, non-toxic and tasteless, non-oily, easy to clean, and aging resistance.

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.
