Double-layer glass frame manufactured by foaming fluorocarbon resin and preparation method thereof

Abstract

The invention relates to a double-layer glass frame manufactured by foaming fluorocarbon resin and a preparation method thereof. The double-layer glass frame can be installed on a base body through rails and comprises a frame, two parallel first grooves are arranged at the inner side portion of the frame, and two parallel second grooves are arranged at the outer side portion of the frame. Symmetrical protrusions are arranged on the inner side of each first groove and matched with glass to be assembled. The two parallel second grooves are matched with the rails to be installed. The preparation method comprises the following steps: 1 adopting the fluorocarbon resin as a raw material and performing foaming treatment, wherein the foaming rate is set as 2-3 times of the existing rate; 2 extruding and forming the foaming fluorocarbon resin obtained by the step 1 through a machine; 3 assembling formed frame obtained by the step 2 and the glass; and 4 installing combined glass frame on the base body. Compared with ordinary alloy glass frame, thermal insulation is high, durability is good, no additional gasket is required to be arranged between the glass and the frame body, and the preparation method is simple and easy, can save expenses and reduces cost.

Description

technical field [0001] The invention relates to a double-layer glass frame and a preparation method thereof, in particular to a double-layer glass frame made of foamed fluorine resin and a preparation method thereof. Background technique [0002] Ethylene-tetrafluoroethylene copolymer (ETFE, -[-CH2-CH2-CF2-CF2-]-n), commonly known as fluoroplastic resin, is a copolymer of tetrafluoroethylene and ethylene in a certain proportion. Fluoroplastic. It is also the one with the lightest specific gravity (1.7) among fluoroplastics, translucent, light yellow to brown, and has good radiation resistance. Melting point 265-280°C, decomposition temperature > 300°C, average linear expansion coefficient 1.4910×10°C-1, flammability: self-extinguishing. Operating temperature range: -60~180°C, up to 230°C for a short time. F-40 has good heat resistance, wear resistance and chemical resistance, and its impact strength and electrical insulation performance are also very good. [0003] As...

AI Technical Summary

Problems solved by technology

[0005] Aluminum alloy is mostly used as the frame material of the current double-glazed glass, because the heat insulation of aluminum alloy is small, and it cannot maintain the indoor temperature well in cold regions.

In addition, glass windows are subject to impacts such as strong winds, and such impacts can damage the frame material.

Although it can be replaced by wooden materials, it is susceptible to corrosion and lacks durability

refer to figure 1 As shown, the existing ordinary glass frame is installed on the substrate 1 through the second groove 4 and the track 5 at the bottom, and the glass 6 is fitted with the frame body 2 through the first groove 3. Gaskets 32 also need to be arranged between the frames 2, making the installation process more cumbersome
