Coextruded wood/plastic composites with excellent weathering resistance

摘要

PURPOSE: co-extrusion synthetic wood there is improved weatherability to lessen with to ultraviolet color-changing, to enhance stability and weatherability. ;CONSTITUTION: co-extrusion synthetic wood has improved weather resistant polymer/timber dust synthetic wood. Synthetic wood includes that the wood powder of 100-15 parts by weight, the UV stabilizer of 1-5 parts by weight and/or UV stop/absorb pigment and additive 0.2-3 parts by weight, the polymer based on 100 parts by weight. The polymer is selected from PP, PE, PVC, PS, PMMA, the polymer of PET. The additive is one or more selected from antioxidant, coupling agent and lubricant. Antioxidant, coupling agent, lubricant are respectively with 0.2-1 parts by weight, 1-3 parts by weight and 1-3 parts by weight, the polymer based on 100 parts by weight. ;The 2013 of copyright KIPO submissions
