[0004] In the prior art, an aluminum-wood composite window structure is that the aluminum alloy main frame is an independent component, which bears the structural strength of the door and window. The aluminum frame and the wooden frame are made separately and finally connected by nylon buckles or plastic bridges. The gap between them is prone to condensation, which is not good for wood protection
Another kind of aluminum-wood composite door and window is that the finished window is made of aluminum alloy profiles on the outside, and wooden profiles on the inside. The wooden profiles on the inside bear the structural strength of the doors and windows, and the aluminum alloy profiles are set on the outside of the wood profiles for waterproof, dustproof, and UV protection; Wood profiles also have heat preservation, humidity control and high decorative effects; but the processing of this wood profile is more complicated, and the quality requirements for wood materials are higher
[0005] Secondly, the bonding degree of composite materials (especially metal and wood composites) is not high, so cracking and degumming will occur when adhesives are used for bonding. At present, there is no specific adhesive for metal and wood composite materials on the market. Most adhesives have average adhesion, short service life and contain harmful substances that will cause environmental pollution
For example, the publication date is July 8, 2015, and the Chinese patent with the publication number CN103773284B discloses a weather-resistant water-based adhesive and its preparation method. wood composites
[0006] In addition, the aluminum-wood composite materials obtained by the adhesives and processes of the prior art can only be used for interior decoration of rooms, such as sliding doors in kitchens and bathrooms, and cannot be used for external doors and windows, because the temperature difference between the inside and outside of external doors and windows is large, and aluminum-wood composite materials The material is easy to warp, deform and crack, and the outside is exposed to the sun and rain, the adhesive is easy to age, and the aluminum-wood composite material is easy to crack

Abstract

The invention provides a manufacturing method of a composite sectional bar for a door and a window. The manufacturing method comprises the steps of: preparing a non-metal plate; preparing a metal sectional bar, wherein the metal sectional bar is made of a light alloy; applying an adhesive to the surface of the non-metal plate or the metal sectional bar; performing blank-assembly according to a preset blank-assembly structure to obtain a composite sectional bar plate blank, wherein the preset blank-assembly structure is that at least one side of the metal sectional bar is provided with the non-metal plate; laminating and molding the composite sectional bar plate blank, relieving the pressure to obtain a semi-finished product of composite sectional bar; post-processing the semi-finished product of composite sectional bar to obtain a finished product of composite sectional bar. The composite sectional bar for the door and the window is manufactured through compounding of the non-metal plate and the metal sectional bar, thereby improving the heat insulation performance of the composite sectional bar while the structural strength of the composite sectional bar is guaranteed.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a method for manufacturing a composite profile used for doors and windows. Background technique [0002] The building envelope is composed of exterior walls, roofs, doors and windows, and the windows that account for 20%-30% of the entire building area are the parts that emit the most heat, which can be said to be the weak link in the envelope. Door and window energy consumption control is the key to improving building energy efficiency. [0003] Aluminum alloy profiles are mostly hollow structures with light specific gravity. The material is 70 times lighter than bricks of the same volume, and the weight is only 1 / 3 of stainless steel. Aluminum profiles have the characteristics of short production cycle, excellent mechanical properties, and good processing performance, and because aluminum profiles can be bent arbitrarily or formed at one time, and have high processin...
