Outdoor high-weatherability high-strength co-extrusion wood composite floor and manufacturing process thereof

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...

AI Technical Summary

Problems solved by technology

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, which increases the limitations of the plastic-wood floor.
