specific Embodiment approach 1

[0010] Specific implementation mode one: the preparation method of the composite profile with the wood layer bonded to the metal or / and plastic surface of this embodiment adopts the following steps:

[0011] Step 1, decontamination and cleaning the outer surface of the metal or / and plastic profile;

[0012] Step 2. Apply liquid glue evenly on the outer surface of the metal or / and plastic profiles treated in step 1. The temperature of the applied liquid glue is 10°C to 30°C, and then apply the liquid glue with a thickness of 0.3 mm to 30 mm. The inner surface of the wooden layer 1, which has been polished by a sander or sandpaper, is pasted together with the outer surface of the metal or / and plastic profile coated with liquid glue, and then placed on the extruder with a pressure of 5-50T. Squeeze for 0.5 to 4 hours;

[0013] Step 3, after the liquid glue in step 2 dries, the outer surface of the wooden layer 1 is polished with a sander or sandpaper, and the primer is first spr...

specific Embodiment approach 2

[0014] Embodiment 2: The difference between this embodiment and Embodiment 4 is that the temperature of the liquid glue applied in step 2 is 10° C. to 20° C.; the extrusion machine extrudes for 2 to 4 hours at a pressure of 5 to 30 T.

specific Embodiment approach 3

[0015] Embodiment 3: The difference between this embodiment and Embodiment 4 is that the temperature of the liquid glue applied in step 2 is 21° C. to 30° C.; the extruder extrudes for 0.5 to 2 hours at a pressure of 31 to 50 T.

Abstract

The invention relates to a composite section base whose metal or / and plastic surface is adhered with wood layer, and relative preparation method. Wherein, it comprises a metal or / and plastic section bar, and a wood layer (1) adhered on the outer surface of said section bar. The preparation method comprises: 1, treating the outer surface of metal or / and plastic section bar; 2, coating liquid pastern on the outer surface to stick the inner surface of wood layer (1) that coated with liquid pastern to be compressed; 3, coating the outer surface of wood layer (1) to obtain the final section bar. The invention can solve the composite problem of door or window steel-wood section bar, without crack and deformation, while it has better damp-proof and thermal-insulated properties.

Description

technical field [0001] The invention relates to a method for preparing a door and window composite profile. Background technique [0002] At present, the existing anti-theft doors, safety doors, and fire doors are mostly made of metal or / and plastic profiles, and the anti-theft doors, safety doors, and fire doors made of metal or / and plastic profiles have rough outer surfaces, easy to rust, and heavy weight. And the shortcomings of high cost, poor windproof, moisture-proof and thermal insulation performance, and wooden doors and windows have problems of easy deformation, cracking and aging. However, the existing aluminum-plastic-wood structure doors and windows are mostly connected by buckles, and the structure is complex, while metal or / and plastic and wood structure composite profiles have the problem of difficult connection between metal or / and plastic profiles and wood. Contents of the invention [0003] The present invention aims to solve the rough outer surface of e...
