Window material, preparing method and application thereof

Abstract

The invention provides a window material using industrial waste residues as main materials. The raw material includes, by weight, 55 to 70 parts of red mud, 30 to 45 parts of plastics, 0.05 to 4 parts of functional additive A, 3 to 5 parts of functional additive B, 3 to 5 parts of enhancing carrier, and 2 to 5 parts of filler. The plastic is selected from polyethylene, polrvinyl chloride or polypropylene. The functional additive A is selected from impact modifier chlorinated polyethylene (CPE), plasticizer dioctyl adipate (DOA) and a beta crystalline type nucleating agent tetramethylbenzidine (TMB)-5. The functional additive B is selected from processing modifier ethylene propylene diene monomer (EPDM) and impact modifier methyl methacrylate-butadiene-styrene copolymer (MBS). The enhancing carrier is E-glass fiber, and the filler is micas. The window material has the advantages of being high in hardness and not needing steel linings, being ultraviolet resistant, fouling resistant, light in weight, good in sound and heat insulation performances, water proof, fire proof and electricity proof, and having no radioactive contamination and good market prospect and use value.

Description

technical field [0001] The invention relates to the field of recycling industrial waste red mud, in particular to a window material, its production method and application. Background technique [0002] Red mud (Red Mud, Bauxite Residue), also known as red mud, is an industrial solid waste discharged after refining alumina from bauxite. Generally, it contains a large amount of iron oxide, and its appearance is similar to red soil, hence the name. Aluminum smelters generally produce 1.0-2.0 tons of red mud for every ton of alumina produced on average. Major aluminum factories in my country, such as Shandong Aluminum Factory, Shanxi Aluminum Factory, Guiyang Aluminum Factory, and Zhengzhou Aluminum Factory, have abundant red mud wastes that are discarded. According to different raw materials and process conditions, the names of red mud are also different. There are Bayer red mud, sintering red mud, combined red mud, etc. The main components are CaO, SiO 2 , Fe 2 o 3 , Al ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are endless technical solutions for preparing building decoration materials from red mud. However, although these methods make use of red mud, they will produce a large amount of harmful gases in the production process. On the one hand, the harmful gas produced causes environmental pollution again

Moreover, because the red mud is alkaline, the building materials without dealkalization in the prior art are cheap, but they are easy to reverse alkali and are extremely inconvenient to use. The cost of dealkalized red mud building materials is high and has no use value

[0005] Generally, aluminum alloy window materials in the market are expensive, heavy, high thermal conductivity, poor heat insulation performance, and extremely inconvenient to use; while plastic steel window materials are not hard enough, slightly inferior in fire resistance, and poor in aging resistance.

[0006] The invention patent application with the application number 200910119558.1 discloses a production method of colored plastic profiles. The PVC plastic door and window profiles produced by this method have the advantages of anti-ultraviolet aging, pollution resistance, not easy to fade, and various color combinations, but their hardness is not enough. Steel rods must be added inside to increase rigidity, while producing radioactive contamination and emitting toxic gases
