Composite material closed boxcar

Abstract

The invention relates to a composite material closed boxcar which comprises a box body, wherein the box body consists of an outer layer, a middle layer and an inner layer. The outer layer consists of a gel coat layer and a structure layer, wherein the middle layer consists of a metal frame and a sandwich glass steel plate, the inner layer is the structure layer, and the structure layer consists of a plurality of polyester resin layers and a fiber layer; and all the layers are connected by using adhesive layers. The composite material closed boxcar has good luster, is colorable, simultaneously has the good performances of water resistance, chemical resistance, corrosion resistance, abrasion resistance, impact resistance and the like, further has toughness, rebound elasticity and good corrosion resistance, light weight and collision rebound elasticity, can effectively prevent small collision and also has the good functions of heat preservation, thermal insulation or anti-freezing property, impact mitigation and noise isolation. The composite material closed boxcar has the advantages of reasonable design, low production cost, easy fabrication, good effects of heat preservation and thermal insulation, strong anti-collision capacity and a wide range of applications.

Description

Technical field [0001] The invention relates to a composite material enclosed freight car compartment, which has good heat preservation, heat insulation and antifreeze effects on the environment in the compartment, and also has the functions of anti-vibration and anti-noise. Background technique [0002] The existing fully enclosed automobile compartments have shortcomings that need to be perfected: the small amount of metal materials will lead to a decrease in the strength or anti-collision ability of the compartment; if the amount of metal materials is large, the weight of the compartment itself will increase, resulting in energy The waste; the traditional carriage only pays attention to the strength requirements, and ignores the anti-vibration and anti-noise ability of the carriage, especially the ability to keep the environment in the carriage, heat insulation, and antifreeze. For example, due to the lack of ventilation and poor thermal insulation performance in traditional c...

AI Technical Summary

Problems solved by technology

[0002] The existing fully enclosed car compartments have some shortcomings that need to be improved: if the amount of metal materials is small, the strength of the compartment or the anti-collision ability will be reduced; if the amount of metal materials is large, the weight of the compartment itself will increase, resulting in energy consumption. waste; the traditional car only pays attention to the strength requirements, but ignores the anti-seismic and anti-noise capabilities of the car, especially the ability to keep warm, heat-insulate, and freeze-proof the environment inside the car.

For example: due to the lack of ventilation and poor thermal insulation performance of traditional cars, in summer, the temperature inside the car is almost twice the temperature outside the car; in winter, the temperature inside the car is almost equal to the temperature outside the car

[0003] The above shortcomings are very unfavorable for the performance matching of the car and the scope of application for transporting goods.
