Embodiment 1

[0035] The invention is a wood-plastic co-extruded door and window profile, such as figure 1 As shown, it includes PVC-U plastic profile 1 and wood-plastic profile 2, which is a wood-plastic co-extrusion profile composed of PVC-U plastic profile 1 and wood-plastic profile 2; it is the combination of wood-plastic profile raw materials and PVC-U After the raw materials of the plastic profiles are dried at 70°C by the dryer, the raw materials are sent to the wood-plastic extruder and the PVC-U profile extruder respectively, and the initial temperature of each extruder is 110°C. , after reaching the metering section of the main engine, melt and plasticize at a temperature of 175°C, and then input the materials extruded synchronously by two plastic extruders into a composite co-extruded profile forming mold at 175°C It is formed at a temperature of ℃, and then vacuum-formed in a vacuum setting mold, then water-cooled and formed in a vacuum water tank at 5°C to 15°C, and then made b...

Embodiment 2

[0039] The invention is a wood-plastic co-extruded door and window profile, such as figure 1 As shown, it includes PVC-U plastic profile 1 and wood-plastic profile 2, which is a wood-plastic co-extrusion profile composed of PVC-U plastic profile 1 and wood-plastic profile 2; it is the combination of wood-plastic profile raw materials and PVC-U After the raw materials of the plastic profiles are dried at 75°C by the dryer, the raw materials are sent to the wood-plastic extruder and the PVC-U profile extruder respectively, and the initial temperature of each extruder is 115°C. , after arriving at the metering section of the main engine, it is melted and plasticized at a temperature of 178°C, and then the materials extruded synchronously by two plastic extruders are input into a composite co-extrusion profile forming mold, It is formed under high temperature, and then vacuum formed in the shaping mold, and then water-cooled and formed in a vacuum water tank at 10°C, and then it i...

Embodiment 3

[0041] The invention is a wood-plastic co-extruded door and window profile, such as figure 1 As shown, it includes PVC-U plastic profile 1 and wood-plastic profile 2, which is a wood-plastic co-extrusion profile composed of PVC-U plastic profile 1 and wood-plastic profile 2; it is the combination of wood-plastic profile raw materials and PVC-U The raw materials of the plastic profiles are dried at a temperature of 70°C to 80°C by the dryer, and then sent to the wood-plastic extruder and the PVC-U profile extruder respectively. The initial temperature of each extruder is 120°C. Heating step by step, after reaching the metering section of the host machine, melting and plasticizing at a temperature of 175 ° C ~ 180 ° C, and then the materials extruded synchronously by two plastic extruders in proportion are input to a composite co-extruded profile forming In the mold, it is formed at a temperature of 190°C, and then vacuum-formed in a vacuum setting mold, then water-cooled and fo...

Abstract

The invention relates to the technical field of special sections required by manufacturing of building doors and windows, in particular to a wood-plastic co-extruded section for doors and windows, which is integrally formed by a PVC-U(polyvinyl chloride unplasticized) plastic section and a wood-plastic section. Wood-plastic section raw materials and PVC-U plastic section raw materials are dried in a drier at a temperature of 70-80 DEG C, then sent into a wood-plastic extruder and a PVC-U section extruder respectively to be gradually heated at an initial temperature of 110-120 DEG C, and melted and plasticized at a temperature of 175-180 DEG C in a main unit metering section, the materials synchronously extruded by two plastic extruders are inputted into a composite co-extruding section forming mould for forming at a temperature of 175-190 DEG C, then subjected to vacuum forming in a vacuum forming mould before water cooling forming in a vacuum water tank at a temperature of 5-15 DEG C, and finally subjected to drawing, cutting and conventional subsequent processing procedures to make the wood-plastic co-extruded section. By means of wood indoors and plastic outdoors, each performance index and heat insulation performance required by windows and doors are improved and the gap in the technical field of window-door special section plastic-wood composite can be filled.

Description

technical field [0001] The invention relates to the technical field of profiled materials required for processing and manufacturing building doors and windows, in particular to a wood-plastic co-extruded door and window profile. Background technique [0002] At present, the building doors and windows used in the construction industry can be divided into the following categories: [0003] Solid wood doors and windows: Solid wood doors and windows are mostly used indoors. Due to the characteristics of wood, pure solid wood doors and windows are rarely used outdoors. [0004] Aluminum-clad wood window: The outer layer is made of aluminum alloy profiles, and the interior part is made of wood. It looks like wood indoors. Because wood is a scarce resource, the price is high, and the maintenance cost is high. The moisture-proof performance is poor and it is easy to crack . [0005] Steel doors and windows: used for fire doors, color steel windows for general buildings, the propor...
