Abstract

The invention discloses a railway freight transport open wagon vertical column and a preparation method thereof. The wagon vertical column is prepared by composite material, flexibilizer, filler and bulking agent in the mass ratio of 100:(3 to 15):(0.1 to 10):(0.1 to 5), wherein the composite material is prepared from the following constituents in part by weight: 60 to 80 parts of nylon resin, 20 to 40 parts of reinforced fiber, 0.1 to 5 parts of coupling agent, 0.5 to 3 parts of nucleating agent, 0.2 to 3 parts of heat stabilizer, 0.3 to 1.5 parts of antioxygen, and 0.5 to 1.5 parts of lubricant. The novel wagon vertical column is in a square matrix shape (rounded) according to strength calculation, ANSYS software analysis, isotropy requirements and convenience in use: the section size is 45*45mm, the wall thickness is 6mm, and the outer fillet is 10 mm. The wagon vertical column has sufficient impact strength and bending strength, good weather resistance, balanced blasting stress, good comprehensive performance indexes of rigidity, flexibility and balance, and has the advantages of capability of recycling and the like.

Description

technical field [0001] The invention belongs to the field of polymer material production, and in particular relates to a railway freight gondola car column and a preparation method thereof. Background technique [0002] In the process of transporting logs and other goods, the railway freight gondola car will use the car column, and now the log type car column is more used. It has the advantages of obtaining local materials and being simple and easy to implement. However, the round logs are of different sizes, and the car columns formed are not standardized, not interchangeable and reusable, and discarded after one-time use causes a lot of waste, and the safety is not guaranteed. Contents of the invention [0003] In order to solve the shortcomings of the prior art and meet the application requirements of the new material car column, the present invention proposes a railway freight open car column and a preparation method thereof, aiming at using polymer materials instead ...
