Abstract

The invention discloses a method for manufacturing bamboo / wood-based lining plastic doors and windows. The method comprises a step of: filling a lining material in a cavity of a polyvinyl chloride (PVC) section; and a method for preparing the lining material comprises the following steps of: preparing materials, wherein the lining material consists of the following components in percentage by mass: 45 to 55 percent of regenerated resin, 40 to 50 percent of plant fiber powder, 1 to 5 percent of plant fiber powder surface treating agent, 1 to 5 percent of lubricant and 1 to 5 percent of flexibilizer; uniformly stirring the components, and performing extrusion molding through a mold to obtain a blank material; and finishing the surface of the blank material, so that the finished blank material is fitted with the cavity of the PVC section. The bamboo / wood-based lining plastic doors and windows manufactured by the method have the characteristics of low cost, environment friendliness, high heat preservation and the like.

Description

technical field [0001] The invention relates to an energy-saving door and window in the field of building components, in particular to a preparation method for a bamboo-wood-based plastic-lined door and window. Background technique [0002] Doors and windows are an important part of the building envelope. Although doors and windows occupy a small area in the envelope, they are the most active parts of building heat exchange and heat conduction. The heat loss caused by doors and windows is 5 to 6 times that of the wall. times. Therefore, the development and use of energy-saving doors and windows is an important way to reduce building energy consumption. [0003] Plastic doors and windows, that is, polyvinyl chloride (PVC) is used as the main raw material to make the frame and fan materials of doors and windows. It has the advantages of light weight, easy processing and large-scale mechanized production, accurate size, beautiful appearance, excellent thermal insulation perfo...
