Polymer composite energy-saving door/window structure and processing method thereof

Abstract

The invention relates to the technical field of construction, in particular to a polymer composite energy-saving door / window structure and a processing method thereof. The polymer composite energy-saving door / window structure comprises an outdoor profile and an indoor profile, and is characterized in that the indoor profile and the outdoor profile are connected through fasteners, a galvanized steel keel is arranged between the indoor profile and the outdoor profile, filler layers are arranged in the galvanized steel keel and between the indoor profile and the outdoor profile, and the section of the galvanized steel keel is of 'feng' (Chinese character )-shaped structure. Compared with the prior art, the polymer composite energy-saving door / window structure in composite profile design with three layers utilizes the middle galvanized steel keel as a main bearing core of a window frame, after the galvanized steel keel, the outdoor profile and the indoor profile are fitted, residual internal space is filled with polyurethane foaming rubber, so that the galvanized steel keel, the outdoor profile and the indoor profile are firmly connected. The polymer composite energy-saving door / window structure substitutes aluminum alloy and plastic steel door / window profiles and provides technical conditions for modern energy-saving door / window mainstream materials.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a polymer composite material energy-saving door and window structure and a processing method thereof. Background technique [0002] At present, the well-known building energy-saving door and window profiles in my country are two categories: aluminum alloy profiles and plastic steel profiles. [0003] The aluminum alloy material itself is a high-performance thermal conductivity material with a thermal conductivity of 237w / mK. It is usually used as an electrical radiator or aluminum pan and other products that require rapid heat transfer. The aluminum alloy material is used as a building energy-saving door and window profile. Contrary to the scientific theory of building energy efficiency. Although the production of some doors and windows also uses some bridge-breaking heat insulation measures, it is still difficult to reach the standard value of the energy-saving coefficient presc...

AI Technical Summary

Problems solved by technology

Although some doors and windows have technically used some thermal insulation measures for broken bridges, it is still difficult to reach the standard value of energy-saving coefficient stipulated by the state.

The material cost of aluminum alloy profiles is high and the processing technology is complicated. At the same time, the production process of aluminum alloy materials requires extremely high energy consumption. Using the development concept of low carbon and energy saving to weigh, aluminum alloy is used as the mainstream material of energy-saving doors and windows in my country's buildings. Obviously Does not meet my country's economic growth and energy conservation and emission reduction requirements

[0004] Although the existing plastic-steel door and window profiles in my country have the advantages of low material cost, simple processing technology, low production energy consumption, and heat transfer coefficient of only 0.14w / m.K, the mechanical strength of plastic-steel profiles is lower than that of aluminum alloy profiles. The coefficient of cold shrinkage is higher than that of aluminum alloy profiles, and due to the limitations of traditional plastic-steel corner joint technology on the strength of corner joints, as well as the limitations of technical factors such as anti-aging index and monotonous color, it cannot be a large part of my country's building energy saving. Mainstream materials for doors and windows

[0005] The existing door and window profiles are generally divided into two groups: solid and hollow. The solid profiles have high consumables and are not conducive to transportation. Although the hollow profiles are light, they have low strength and are easy to be bent and damaged; and the supplier needs to purchase the profiles. According to the needs of customers, they can cut, weld and assemble the finished products by themselves, so that the remaining materials after cutting are also included in the transportation cost of profiles, which indirectly increases the cost of finished products
