Problems solved by technology

[0002] With the rapid development of the automobile industry, more and more wastes are discharged in the automobile industry. The annual waste of automobile tires alone reaches hundreds of millions. The traditional treatment methods for these wastes are landfill or accumulation. The landfill and accumulation of a large number of waste tires not only causes a waste of resources, but also poses a serious threat to the environment. Long-term stockpiling or landfilling will lead to changes in the soil structure, and will also breed mosquitoes and cause serious damage to the environment. The spread of diseases will also cause waste tires to produce sulfur-containing substances during the long-term decomposition process, which will pollute the environment
[0003] Based on this, a large number of researchers have begun to recycle waste tires to produce reclaimed rubber after modification. However, due to the high content of sulfur in waste tires, the ash content after production into reclaimed rubber powder is relatively large, making The amount of waste tires added in the field of reclaimed rubber production is small, making it difficult to process waste tires to meet the amount of waste tires produced, and it will also be added to reclaimed rubber products, resulting in poor performance of the prepared reclaimed rubber products. It hinders the recycling of waste tires in the field of reclaimed rubber
In particular, it hinders the recycling of waste tires to prepare rubber flooring. The reason for this is that people's living standards are constantly improving, and the requirements for the comfort of daily life are getting higher and higher. The presence of ash and sulfur-containing components and the poor activity of rubber powder prepared from waste tires make the rubber floor prepared by recycling waste tires easy to delaminate, low in strength, and have poor sound insulation and shockproof effects, which hinders the use of rubber floor in construction. field application

Abstract

The invention relates to the technical field of preparing rubber floors by recycling waste tires, in particular to a method for manufacturing rubber floors by recycling waste tires. After crushing, two times of magnetic separation, two times of grinding, burdening, modeling and coloring are conducted on the waste tires, the waste tires are dried and molded in a high-temperature furnace at the temperature of 160-180 DEG C and the pressure of 0.5-1 MPa, so that the cost of the manufactured rubber floors is low, the utilization rate of the waste tires is high, the temperature is low when the rubber floors are molded, pressure is low, energy consumption of the rubber floors is low, the requirement for equipment is low, the technical process is simple, and the manufacturing cost of the rubber floors is reduced. A noise reduction experiment is conducted on the rubber floors, the noise reduction index of the rubber floors is 23-35 dB, and the rubber floors can be applied to modern city floor buildings to improve the sound insulation effect between upper floors and lower floors. Meanwhile, a buffering experiment is conducted on the rubber floors so that objects falling from the height of 5-6 m cannot cause large-range impacts on the floors, the vibration reduction effect can be achieved, and the rubber floors are widely suitable for sound insulation and shock absorption of vehicles, ships and buildings.
