Wood-plastic window frame

Abstract

A wood-plastic window frame is characterized by comprising horizontal section bars (1) and longitudinal section bars (2) which mutually perpendicular to each other, wherein each of the horizontal section bars (1) and the longitudinal section bars (2) include two-layer structures, wooden core layers (11 and 21) and wood-plastic coating layer (12 and 22), and tenon-and-mortise connecting structures are arranged the ends of the horizontal section bars (1) and the ends of the longitudinal section bars (2) and are integrally formed by the wooden core layers. The wood-plastic window frame is simple in structural connection, does not need additional matched hardware, is firm in structure, convenient to dismount, low in cost and long in service life. In addition, the wooden core portions are coated with a wood-plastic composite material, the wooden core portions can be protected against moisture absorption and deformation, and the tenon-and-mortise structures are easily processed for the wooden core portions, connection is simple, convenient and firm, the whole window frame is higher in bonding strength and does not easily deform, and the service life of the window frame is also prolonged.

Description

technical field [0001] The invention relates to a board, in particular to a wood-plastic window frame. Background technique [0002] Most of the commercially available window frames are made of aluminum alloy, and the connection structure is mostly connected by hardware. On the one hand, the cost of both the window frame itself and the hardware is relatively high; The window is inconvenient to open; thirdly, the hardware connection structure and operation process are complicated, which wastes manpower and material resources. [0003] Wood-plastic composite material is a new type of ring material, commonly used in indoor and outdoor decorative wall panels, floors, drainage pipes and other pipes and door and window frames and other special-shaped materials. It is made of plastic as the base material and filled with materials such as wood, bamboo and crop straw. , has the advantages of waterproof and moisture-proof, low moisture absorption, low deformation, and good mechanical...
