Example Embodiment

[0035] In order to easily understand the technical means, creation features, achievement goals and effects of the present invention, the present invention will be further described below with reference to the specific figures.

[0036] like figure 1 As shown, a cold-proof material for a subway car includes a cold-proof base layer 1, and an insulating layer 2 and an adhesive layer 3 are respectively hot-pressed and laminated on both sides of the cold-proof base layer 1. The heat-insulating layer 2 is made of aluminum foil, and the cold-proof base layer 1 is made of foam. Finished melamine cotton.

[0037] Because the cold-proof material is made of a cold-proof base layer 1, an insulating layer 2 and an adhesive layer 3, wherein the heat-insulating layer 2 is made of aluminum foil, and the cold-proof base layer 1 is made of foamed melamine cotton, and the aluminum foil has excellent thermal insulation. Thermal effect, melamine cotton has excellent sound absorption, flame retard...

Abstract

The invention discloses a cold-proof material for subway carriages and a preparation process of the cold-proof material, and belongs to the technical field of heat-insulation cold-proof materials. Comprising a cold-proof base layer, a heat insulation layer and an adhesive layer are compounded on the two sides of the cold-proof base layer in a hot-pressing mode respectively, the heat insulation layer is made of aluminum foil, and the cold-proof base layer is made of foamed melamine cotton. By means of the cold-proof material, the heat preservation and insulation effects of the cold-proof material are excellent, the performance of all parts of the subway train can be kept normal in the extremely severe cold environment, and therefore safe and stable operation of the subway train is guaranteed.

Description

technical field [0001] The invention relates to a cold-proof material for subway cars and a preparation process thereof, and belongs to the technical field of heat-insulating and cold-proof materials. Background technique [0002] In today's high-speed and high-efficiency society, more convenient and rapid traffic development is required. Various motion carriers (vehicles) have been designed with light weight and heat insulation for energy conservation, environmental protection and high speed. For example, most aviation materials have low density, high Strength, no thermal expansion and cold contraction, no metal fatigue, flame retardant, non-toxic, low temperature resistance, etc. [0003] In recent years, with the vigorous development of my country's subway industry, the requirements for the design and performance of subway trains have also continued to develop and progress, and become increasingly strict. The speed of subway trains, the service life, and the selected mat...
