Plastic railway sleeper formula process

Abstract

The invention provides a plastic railway sleeper formula process which is low in manufacturing cost, good in elasticity and long in service life. The plastic railway sleeper formula process is characterized in that a plastic railway sleeper formula comprises: 46-60 parts of waste polyvinyl chloride waste wire skin (PVC), 18-25 parts of waste tire rubber powder (WRP), 1-5 parts of fluoroplastic waste wire skin (PTFE), 1-5 parts of polyperfluorinated ethylene propylene waste wire skin (FEP), 1-15 parts of polypropylene waste wire skin (PP), and the like. According to the invention, wastes are utilized as materials, so that not only can product cost be lowered, but also a problem of waste plastic white pollution and waste rubber black pollution is solved to a certain extent, and therefore, environment is protected. Waste rubber is used as the main material to ensure elasticity of the plastic sleeper, so that good buffer action can be achieved well during use. The plastic sleeper produced by the plastic railway sleeper formula process disclosed by the invention is good in environment-friendly effect, long in service life, good in elasticity, good in insulativity, not fractured at -60 DEG C, and good in cold resistance, and therefore, the plastic sleeper is an ideal product for replacing a cement railway.

Description

[0001] technical field [0002] The invention relates to the field of construction engineering, in particular to a railway sleeper. Background technique [0003] Sleepers, also known as sleepers or road sleepers, are the basic material for laying railways and one of the components of railway rails. They are directly connected to the bottom of the rails and can stabilize the position of the rails. The sleepers are used to prevent the rails from shifting when the train passes by and cause danger. , the pressure generated by the train passing by can also be evenly distributed on the ballast, so that the train runs more stably. At present, sleepers are generally divided into wooden sleepers, reinforced concrete sleepers, steel sleepers, and composite material sleepers; in daily life, wooden sleepers are easy to make, light in weight, and widely used, but because sleepers are widely used outdoors, wooden sleepers Sleepers are extremely easy to corrode and need to be replaced i...

Problems solved by technology

At present, sleepers are generally divided into wooden sleepers, reinforced concrete sleepers, steel sleepers, and composite material sleepers; in daily life, wooden sleepers are easy to make, light in weight, and widely used, but because sleepers are widely used outdoors, wooden sleepers Sleepers are extremely easy to corrode and need to be replaced in a short period of time. The cost is huge, and with the improvement of national environmental protection awareness, logging is gradually not allowed, so wooden sleepers have to gradually withdraw from the market; reinforced concrete sleepers and steel sleepers are not manufactured. Timber needs to be felled, and its life is long, so it does not need to be replaced frequently, but its elasticity is poor, it cannot play a buffer role, and it is not conducive to the running of the train; although the composite sleeper overcomes the above problems, its cost is very high. If it is used in large quantities Composite sleepers require huge expenditure, which virtually increases the cost of the railway, is not conducive to the use of the railway, and increases the burden on the country, builders and passengers, and the railway will lose its unique advantages
