Aluminum-wood intergrowth material and preparation method thereof

Abstract

The invention discloses an aluminum-wood intergrowth material. The aluminum-wood intergrowth material comprises an aluminum section and a wood section; the aluminum section is provided with a groove which is matched with the wood section; and the inner side of the groove is provided with teeth which are embedded in the wood section to connect the aluminum section and the wood section rigidly. Besides, the invention further provides a method for preparing the aluminum-wood intergrowth material. A tooth form design of the aluminum section groove and a rolling process increase the bite force of the combined wood section and aluminum section greatly, and consequently make the wood section and aluminum section combined tightly. Experimental results show that the aluminum-wood intergrowth material can bear a longitudinal shearing force of 6,000 to 7,000 N (in the length of 100 mm) and a transverse tensile force of 5,000 to 6,000 N (in the length of 100 mm). The aluminum-wood intergrowth material is highly favorable for improving the strength of doors and windows of buildings, and improving the water tightness, gas tightness and wind load resistance of the doors and windows.

Description

technical field [0001] The invention relates to the field of building materials, and more specifically relates to an aluminum-wood symbiotic material and a preparation method thereof. Background technique [0002] Aluminum profiles and wood profiles have excellent physical properties respectively, so they are widely used in the field of building materials. [0003] There are roughly two types of existing aluminum-wood composite profiles, including interspersed aluminum-wood composite profiles and artificial extruded wood profiles. Among them, the interspersed aluminum-wood composite profile adopts a low-density solid wood profile, that is, an aluminum-wood composite profile formed by penetrating the low-density solid wood profile into the cavity or notch of the aluminum alloy profile. The deformation of the wood of the aluminum-wood composite profile cannot be restrained by the aluminum alloy profile, and at the same time, because it uses low-density solid wood, it is easy ...

AI Technical Summary

Problems solved by technology

[0004] Interspersed aluminum-wood composite profiles and artificial extruded wood profiles cannot bear longitudinal shear force and transverse tensile force due to their connection combination.

When this profile is used as a building door, window or curtain wall, its own load and wind pressure can only be borne by aluminum alloy, so the strength of this aluminum-wood composite profile is poor.
