Embodiment 1

[0012] The railway box car insulation layer is composed of 100 parts of epoxy resin (such as: E-51, E-618 and other models), 85 parts of epoxy curing agent (such as: 115, 125, 140 and other models) according to the ratio of parts by weight, 36 parts of industrial grade alcohol (more than 95%), 35 parts of short fiber (commonly known as fluff or plush), 32 parts of thickening powder (such as polyphenyl powder, perlite and other light heat insulation powder), 25 parts of color masterbatch and hair The foaming agent is composed of 0.8 parts. The short fiber can be nylon 66 or nylon 6, with a thickness of 1.5-3.0D and a length of 0.3-0.6mm. The fineness of the thickening powder is 200-1000 mesh. The agent is composed of aluminum powder and saturated sodium hydroxide solution, and the weight-number ratio of the aluminum powder and the saturated sodium hydroxide solution is 2:1 or 1.5:1 or 1:1, and the fineness of the aluminum powder is 200-1000 mesh.

Embodiment 2

[0014] The railway box car insulation layer is composed of 140 parts of epoxy resin (such as: E-51, E-618 and other models), 60 parts of epoxy curing agent (such as: 115, 125, 140 and other models) according to the ratio of parts by weight, 50 parts of industrial grade alcohol (more than 95%), 24 parts of short fiber (commonly known as fluff or plush), 45 parts of thickening powder (such as polyphenyl powder, perlite and other light heat insulation powder), 16 parts of color masterbatch and hair The foaming agent consists of 1.6 parts, and the type of said short fiber is nylon 66 or nylon 6, the thickness is 1.5-3.0D, and the length is 0.3-0.6mm. Said thickening powder fineness is 200~1000 orders, and foaming agent can adopt aluminum powder and sodium hydroxide saturated solution, and the weight-number ratio of aluminum powder and sodium hydroxide saturated solution is 2: 1 or 1.6: 1 or 1:1, the fineness of aluminum powder is 200-1000 mesh.

Embodiment 3

[0016] The railway boxcar insulation layer is composed of 120 parts of epoxy resin (such as: E-51, E-618 and other models), 73 parts of epoxy curing agent (such as: 115, 125, 140 and other models) according to the ratio of parts by weight, Composed of 42 parts of industrial grade alcohol (above 95%), 30 parts of short fiber, 39 parts of thickening powder (such as polyphenyl powder, perlite and other light heat insulation powder), 20 parts of color masterbatch and 1.2 parts of foaming agent. The short fiber type mentioned is nylon 66 or nylon 6, the thickness is 1.5-3.0D, and the length is 0.3-0.6mm. The fineness of said thickening powder is 200-1000 mesh, and the foaming agent is aluminum powder and saturated sodium hydroxide solution, and the weight-number ratio of aluminum powder and saturated sodium hydroxide solution is 2:1 or 1.5:1 or 1 : 1, the fineness of aluminum powder is 200-1000 mesh.

Abstract

This is a kind of railway boxcar thermal insulation layer, which comprises epoxy resin 100 - 140 shares, epoxy firming agent 60 - 85, alcohol 36 - 50, short fibre 24 - 35, thickening powder 32 - 45, master batch pigment 16 - 25 shares and vesicant 0.8 - 1.6 shares according to weight shares. Its producing method is that mix epoxy resin, alcohol, short fibre and thickening powder, then add epoxy firming agent and vesicant, lay them still after prepared; pour mixed materials into hopper, smear them on the inner surface of the railway boxcar body using pressure gun method; drying, haul the train body first time smeared into drying room, and gradually increase temperature to 60 - 70 Deg. C in 20 - 30 minutes, then continuously heat it for 40 - 60 minutes; second time smear, smear for the second time when the train body is cooled to room temperature, smear the inner surface of the train body for 5 - 8 times, then drying and clean. It has good heat insulation effect, light weight, small usage space, fire retarding and anticorrosion functions and long service life.

Description

technical field [0001] The invention particularly relates to a heat insulation layer for a railway box car and a production method thereof. Background technique [0002] The railway boxcar is a means of transportation for transporting fruits, vegetables and other items. The existing railway boxcar body is made of a boxcar base made of thin steel plates, a painted bamboo board and used to fix the bamboo board on the boxcar base. The steel pendant and the bolts on the steel pendant are composed. The problem of the railway boxcar with this structure is that the weight of the whole boxcar is heavy due to the use of bamboo boards as the heat insulation layer, and the weight of each car body is about 3 tons, which increases the self-weight of the train and cannot meet the speed of the train. Requirements, while reducing the load and volume of the train. In addition, the bolts on the steel pendant can easily scratch the cargo in the car body. Contents of the invention [0003]...
