Description

technical field [0001] The invention relates to a formula and a preparation method of a decorative profile, in particular to a formula and a preparation method of an extruded wood-plastic foamed decorative profile. Background technique [0002] With the reform and opening up, people's lives are further improved, and the architectural decoration market is developing rapidly, especially the demand for decorative profiles is increasing, including doors, frames and various lines. In the past, these decorative profiles were all made of high-quality natural wood, but there are many problems with wood. First, wood is a non-renewable resource. Using wood to make decorative profiles is limited by resources; secondly, using wood as decorative profiles is limited by the length of raw materials. The original length of the wood may not meet the needs of some decorative profiles; 3. Due to the natural characteristics of the wood, there may be knots, holes, holes and color differences in t...
