Plastic-steel door and window unit with heat preservation and sound insulation functions and preparation process of plastic-steel door and window unit

Abstract

The invention relates to the technical field of plastic-steel doors and windows, and discloses a plastic-steel door and window unit with heat preservation and sound insulation functions and a preparation process of the plastic-steel door and window unit. The plastic-steel door and window unit comprises a plastic-steel door and window frame body, wherein laminated glass is fixedly installed in the middle of the plastic-steel door and window frame body, a PVC plate layer is arranged on the outermost layer of the plastic-steel door and window frame body, a glass wool cloth layer is arranged on the inner surface of the PVC plate layer, a composite filler layer is arranged on the inner surface of the glass wool cloth layer, a foaming agent core is arranged on the inner surface of the composite filler layer, a steel plate layer is arranged on the inner surface of the foaming agent core, a silencing cavity is formed on the inner surface of the steel plate layer, a silencing rod is arranged in the silencing cavity, a heat preservation layer is arranged on the inner surface of the silencing cavity, a waterproof layer is arranged on the inner surface of the heat preservation layer, and a fireproof layer is arranged on the inner surface of the waterproof layer. The plastic-steel door and window unit prepared with the preparation process of the plastic-steel door and window unit with heat preservation and sound insulation functions has the characteristics of light weight, good weather resistance, acid and alkali corrosion resistance, high strength, good heat preservation and sound insulation performance and long service life.

Description

technical field [0001] The invention relates to the technical field of plastic-steel doors and windows, in particular to a plastic-steel door and window with thermal insulation and sound insulation and a preparation process thereof. Background technique [0002] At present, noise has become a major environmental pollution, and people pay more and more attention to the acoustic environment in residential rooms, especially those facing the street. The method of sound windows is a relatively passive means to solve traffic noise, but its effect is obvious. Practice has proved that in areas with serious road noise, sound insulation windows can reduce indoor noise to below 30dB, which meets the "Acoustic Environmental Quality Standard" Requirements of GB3096-2008 As a common building tool, windows are used in various buildings. The existing energy-saving windows have simple structures, large specific heat capacity of materials, and large energy exchange between indoors and outdoor...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a plastic-steel door and window with thermal insulation and sound insulation and its preparation process, which can solve the problem of existing energy-saving windows due to their simple structure, large specific heat capacity of materials, and relatively poor energy exchange between indoors and outdoors. large, resulting in easy loss of indoor heat, poor thermal insulation effect, and although the traditional plastic-steel window adopts double-glazed and vacuum-sealed, the sound insulation effect is not obvious, and the problem of sound transmission cannot be effectively weakened; Plastic steel doors and windows with thermal insulation and sound insulation, light weight, good weather resistance, acid and alkali corrosion resistance, high strength, good thermal insulation and sound insulation performance, long service life, effectively solving existing technical problems
