Embodiment 1

[0039] See attached figure 1 Shown, the step of making this kind of high-speed train lightweight car window is as follows:

[0040] Step 1. Chemically strengthening the first glass layer 1 and the second glass layer 5 with a thickness of 1.8mm, the chemical strengthening temperature is 415°C, and the time is 6h;

[0041] Step 2: Plating SiO sequentially on the PET film 3 2 and NiO x coating, and repeated 2 times, where X=0.7, SiO 2 and NiO x Coating thicknesses are 150nm and 100nm respectively;

[0042] Step 3, the first glass layer 1, the first film layer 2, the PET film 3, the second film layer 4, and the second glass layer 5 are sequentially stacked and laminated, and vacuum bagged;

[0043] Step 4. Send the completed glass into an autoclave for hot pressing to form an inner laminate. When the inner laminate is hot pressed, the cold extraction time is 50 minutes, the hot pressing temperature is 125°C, and the equilibrium time is 110 minutes;

[0044] Step 5. The third...

Abstract

The invention relates to a lightweight train window for a high-speed train and a manufacturing method of the lightweight train window. The train window is of a hollow structure, a sandwich structure on the inner side comprises a first glass layer (1), a first film layer (2), a PET film (3), a second film layer (4) and a second glass layer (5) from indoor to outdoor sequentially; a sandwich structure on the outer side comprises a third glass layer (8), a third film layer (9), a fourth glass layer (10), a fourth film layer (11) and a fifth glass layer (12); the first glass layer (1) and the second glass layer (5) are chemically strengthened glass, and the thicknesses are 1.8 mm-2.0 mm; the first film layer (2) is low frequency sound insulation PVB, and the thickness is 0.38 mm; and the second film layer (4) is high frequency sound insulation PVB, and the thickness is 0.76 mm. The sound and thermal insulation performance of the train window is good. Weighting sound reduction index (Rw) isnot lower than 46 dB, the heat transfer coefficient (K) is smaller than 1.0 W/(m<2>.K), and the weight is only 70% of traditional high-speed train side window glass.

Description

technical field [0001] The invention relates to a lightweight window for high-speed trains and a manufacturing method thereof, belonging to the technical field of product molding. Background technique [0002] As the main artery of the national economy, the important national infrastructure and popular means of transportation, the railway plays an important role in the economic and social development of our country. The plan proposes to vigorously develop high-speed railways, basically build a fast railway network, and at the same time continuously improve the modernization level of rolling stock equipment, which brings historical opportunities for the rapid development of China's high-speed rail rolling stock equipment. It can be seen that high-speed trains, especially trains with a speed of more than 350Km per hour, will become the mainstream equipment for future international and domestic railway development. At the same time, the increase in train speed also puts forwar...
