Embodiment Construction

[0018] The polymer anti-crawling material for railways includes the following weight components: rigid polyethylene compound 55wt%-65wt%; stabilizer 1.5wt%-2.5wt%; reinforcing and toughening agent 15wt%-25wt%; 8wt%-12wt% of additives; 4wt%-6wt% of processing aids; 2.5wt%-3.5wt% of lubricants. The optimized weight components of this anti-crawling material are as follows: 60wt% of rigid polyethylene compound; 2wt% of stabilizer; 20wt% of reinforcing and toughening agent; 10wt% of impact modifier; 5wt% of processing aid; 3wt% of lubricant .

[0019] The anti-crawling material also includes any one or a combination of colorants, fillers and flame retardants. The colorant is a black colorant, and in this embodiment, the colorant is carbon black. The stabilizing agent is any one or a combination of three salts, di-salts and stearates; the reinforcing and toughening agent is any one or a combination of two in calcium carbonate and glass fibers; The impact modifier is any one of CP...

Abstract

The invention belongs to the technical field of railway accessories, and particularly relates to a railway polymer anti-creeping strut material and a railway polymer anti-creeping strut which are used for solving the technical problems that the materials in the prior art are low in properties and the like. The anti-creeping strut material comprises the following compositions in percentage by weight: 55%-65% of rigid polyethylene compound, 1.5%-2.5% of stabilizer, 15%-25% of reinforcing toughing agent, 8%-12% of impact modifier, 4%-6% of processing aids and 2.5%-3.5% of lubricant. Compared with the prior art, the railway polymer anti-creeping strut material and the railway polymer anti-creeping strut have the advantages of being reasonable to combine, easy to process and manufacture, low in production cost, good in mechanical property and long in service life.

Description

technical field [0001] The invention belongs to the technical field of railway accessories, and in particular relates to a polymer anti-climbing brace material for railways and a polymer anti-climbing brace for railways. Background technique [0002] Due to the longitudinal effect of the train running, the rails even drive the sleepers to move longitudinally. This phenomenon is called line crawling. Line crawling will cause uneven rail joints and skewed sleepers, which will cause great damage to the track and endanger driving safety. For this reason, anti-climbing devices and anti-climbing braces need to be installed on the railway. [0003] The anti-climbing braces in the prior art are usually made of reinforced concrete, wood or stone. Although reinforced concrete and stone have high hardness and will not rot, they are prone to breakage during use. After the wood has been treated with anti-corrosion, although the service life can be extended, it will still rot, and its ...
