Problems solved by technology

[0003] Under the current situation, wood-plastic exterior wall panels and exterior wall insulation are still in the field of one or two different materials; there is no better production method for wood-plastic exterior wall panels with functions of fire prevention and heat preservation that can solve the above problems; in addition, the current The main raw materials of some wood-plastic panels are wood powder, plastic and additives, but the amount of wood powder required by the existing raw material formula is relatively large, and in consideration of environmental protection, the greater the demand for wood powder, the more wood will be felled. More, not conducive to environmental protection, and the cost is relatively high

Abstract

The invention discloses a production method of a wood plastic composite (WPC) external wall panel, comprising the steps: 1) WPC compounding; 2) extruder design; 3) mold design; 4) WPC preparation; 5) extrusion; thermal insulation materials and the WPC external wall panel can be molded integrally with the method disclosed by the invention, the extrusion parameters are strictly controlled, and the extrusion effect is improved; the method is environment-friendly, and the production cost is reduced; the purposes of fire protection and thermal insulation can be achieved.

Description

technical field [0001] The invention relates to a wood-plastic exterior wall panel, in particular to a production method of a wood-plastic exterior wall panel with functions of fire prevention and heat preservation. Background technique [0002] PE wood-plastic is mainly used in outdoor floor, wall decoration and other fields. With its complex climate resistance and environmental protection characteristics, the application of wood-plastic on outdoor walls is becoming more and more extensive. At present, wood-plastic exterior wall panels are mainly in two styles: solid and hollow, which play the role of exterior wall decoration and embellishment. In recent years, with the demand for fire-resistant and fire-resistant buildings, and the phenomenon of building groups on fire, the further requirements for materials for wood-plastic exterior walls are mainly reflected in fire-resistant and flame-retardant. To make buildings flame-resistant and fire-resistant, external The wallboa...
