An outdoor high-weather resistance high-strength co-extruded wood-plastic composite floor and its manufacturing process

Abstract

The invention relates to an outdoor high-weatherability high-strength co-extrusion wood composite floor, which comprises the following components by ratio for a surface layer: 40-60 weight part of resin, 30-45 weight part of modified resin, 5-20 weight part of hard wood powder with 120 meshes, 1-10 weight part of calcium carbonate, 1-10 weight part of powdered steatile, 0.1-1 weight part of anti-UV agent, 0.1-1 weight part of anti-oxidant, 0.1-3 weight part of white oil, 1.2-4.2 weight part of maleic anhydride-grafted pp, 0.1-3 weight part of polyethylene wax, 0.1-1.5 weight part of EBS, 0.1-3 weight part of zine stearate, and 2-6 weight part of color powder; and comprises the following components by ratio for an inner layer: 30-45 weight part of HDPE, 35-55 weight part of hard wood powder with 120 meshes, 2-6 weight parts of coupling agent, 5-20 weight part of calcium carbonate, 15-35 weight part of glass fiber, 0.1-3 weight parts of polyethylene wax, 0.1-1.5 weight part of EBS, and 0.1-3 weight part of zine stearate. The outdoor high-weatherability high-strength co-extrusion wood composite floor has the advantages of low cost, strong weatherability, high intensity and environmental protection. The invention also discloses a manufacturing technology of the outdoor high-weatherability high-strength co-extrusion wood composite floor.

Description

technical field [0001] The invention relates to a composite floor, in particular to an outdoor high-weather resistance and high-strength co-extruded plastic-wood composite floor, and also relates to a manufacturing process of the outdoor high-weather-resistant and high-strength co-extruded plastic-wood composite floor. Background technique [0002] As an emerging environmentally friendly industry, wood-plastic composite materials have successfully entered various fields of people's lives because of their strong plasticity and wide range of applications, especially in the construction field, plastic-wood composite floors, wall panels, doors and windows, and furniture. It has gradually become a substitute for traditional materials due to its aesthetics and environmental protection. However, the existing plastic-wood composite floor still has defects such as high processing cost and poor aging resistance, and is especially not suitable for outdoor use in climate change, thereby...
