Problems solved by technology

[0002] As the output of waste tires is increasing year by year, the technical research on the recycling of waste tires to produce reclaimed rubber has generally existed. Improper control leads to the low quality of the rubber floor made of waste tires as raw materials, its poor sound insulation effect, low strength, and other properties are at least 5 percentage points lower than the rubber floor made of natural rubber, and serious It hinders the application of waste tire rubber in the field of rubber flooring; at the same time, the rubber flooring in the prior art generally has low smoothness, poor wear resistance, and peculiar smell, which easily leads to environmental pollution

Embodiment 1

[0022] A kind of rubber floor made of waste tire rubber powder as raw material, its raw material components are by weight 50kg of waste tire rubber powder, PVC powder 10kg, iron oxide powder 3kg, potassium-containing rock powder 4kg, polypropylene powder 1kg, polyurethane curing agent 4kg .

[0023] The polypropylene powder contains 30% wood powder by mass.

[0024] The waste tire rubber powder is prepared by soaking waste tires in ammonia water for 10 minutes, then treating them with microwave radiation for 10 seconds, placing them in a pulverizer, pulverizing them into 20 meshes, and sending them into a magnetic separator. Adjust the temperature to 60°C under a nitrogen atmosphere for 10 minutes, then mix it with the activator at a mass ratio of 1:1, place it in a grinder, grind it into a 50-mesh powder, and then send it to a magnetic separator. Adjust the magnetic separation environment to 100°C, and treat it in an oxygen-free environment with a pressure of 0.02MPa for 20 ...

Embodiment 2

[0031] A kind of rubber floor made of waste tire rubber powder as raw material, its raw material components are by weight 70kg of waste tire rubber powder, 20kg of PVC powder, 7kg of iron oxide powder, 7kg of potassium-containing rock powder, 3kg of polypropylene powder, and 5kg of polyurethane curing agent .

[0032] The polypropylene powder contains 40% wood powder by mass.

[0033]The waste tire rubber powder is prepared by immersing waste tires in ammonia water for 20 minutes, then treating them with microwave radiation for 20 seconds, placing them in a pulverizer, pulverizing them into 30 meshes, and sending them into a magnetic separator. Adjust the temperature to 90°C under a nitrogen atmosphere for 30 minutes, then mix it with the activator at a mass ratio of 1:1, put it in a grinder, grind it into an 80-mesh powder, and then send it to a magnetic separator. Adjust the magnetic separation environment to 120°C, and treat it in an oxygen-free environment with a pressure...

Embodiment 3

[0040] A kind of rubber floor made of waste tire rubber powder as raw material, its raw material components are waste tire rubber powder 60kg, PVC powder 15kg, iron oxide powder 5kg, potassium-containing rock powder 6kg, polypropylene powder 2kg, polyurethane curing agent 4.5 kg by weight kg.

[0041] The polypropylene powder contains 35% wood powder by mass.

[0042] The waste tire rubber powder is prepared by immersing waste tires in ammonia water for 15 minutes, then treating them with microwave radiation for 15 seconds, placing them in a pulverizer, crushing them into 25 meshes, and sending them into a magnetic separator. Adjust the temperature to 70°C under a nitrogen atmosphere for 20 minutes, then mix it with the activator at a mass ratio of 1:1, place it in a grinder, grind it into a 70-mesh powder, and then send it to a magnetic separator. Adjust the magnetic separation environment to 110°C, and treat it in an oxygen-free environment with a pressure of 0.05MPa for 25...

Abstract

The invention relates to the technical field of recycle of rubber powder of junked tires, in particular to a rubber floor prepared with the rubber powder of the junked tires as a raw material and a preparation method thereof. Through selection and raw material matching of the rubber powder of the junked tires, PVC powder, ferric oxide powder, potassium-bearing rock powder, polypropylene powder and polyurethane curing agents, all the raw materials interact with one another to enhance the strength of the rubber floor, reduce volatile substances in the rubber floor, lower the emission of peculiar smells of the rubber floor, lower the environmental pollution rate and increase the sound insulation rate of the rubber floor; particularly through selection of potassium-bearing rock, sylvite in the potassium-bearing rock reacts with the rubber powder of the junked tires, and then the purpose of activating the rubber powder of the junked tires is achieved; in combination with the ferric oxide powder, the activation degree of the rubber powder is increased; in combination with the PVC powder, the polypropylene powder and the polyurethane curing agents, the strength of the rubber powder in the curing and shaping process is guaranteed, and the performance of the rubber floor is improved.
