Thermoplastic elastic running track with anti-bacterial function and manufacturing technology thereof

Abstract

The invention provides a thermoplastic elastic running track with an anti-bacterial function and a manufacturing technology thereof and relates to the technical field of plastic sports field. The thermoplastic elastic running track comprises the following components in parts by weight: 10-20 parts of SEBS, 8-12 parts of SBS, 8-12 parts of EPDM, 25-35 parts of naphthenic oil, 3-5 parts of anti-bacterial master batch, 25-35 parts of inorganic filler, 0.5-1 part of compound antioxidant, 0.3-0.5 part of anti-ultraviolet agent, 0.3-0.5 part of light stabilizer and 0.3-0.5 part of internal and external lubricant. The manufacturing technology for the thermoplastic elastic running track comprises the following steps: quickly mixing SEBS, SBS and naphthenic oil; adding EPDM, anti-bacterial master batch, inorganic filler, compound antioxidant, anti-ultraviolet agent, light stabilizer and internal and external lubricant and slowly mixing; entering into an internal mixer for mixing; entering intoan extruding device for pelletizing, stretching, cooling and cutting into grains, thereby acquiring running track grains; mixing with glue, thereby acquiring an elastic running track base material. The thermoplastic elastic running track is anti-bacterial, environment-friendly, safe, odorless, recoverable, long in service life, short in construction period, simple and green in process.

Description

technical field [0001] The invention relates to a plastic sports field, in particular to a thermoplastic elastic runway with antibacterial function and a manufacturing process thereof. Background technique [0002] The ground pavement currently used in public places with protection requirements such as runways, courts, and kindergartens is a composite rubber or a composite material of rubber and plastic, but this material has the following defects: [0003] 1. It will volatilize a large amount of toxic and harmful gases containing benzene, xylene, polycyclic aromatic hydrocarbons, etc., even seriously exceeding the standard, and the smell is pungent, which seriously affects the health of users, especially young people. [0004] 2. Poor quality, poor durability, limited mechanical properties, low elasticity, tensile strength, aging resistance and ozone resistance. After long-term wind, sun and rain, surface cracks and cracks will appear in 2 to 3 years. Quality problems such...

AI Technical Summary

Problems solved by technology

[0003] 1. It will volatilize a large amount of toxic and harmful gases containing benzene, xylene, polycyclic aromatic hydrocarbons, etc., even seriously exceeding the standard, and the smell is pungent, which seriously affects the health of users, especially young people.

[0004] 2. Poor quality, poor durability, limited mechanical properties, low elasticity, tensile strength, aging resistance and ozone resistance. After long-term wind, sun and rain, surface cracks and cracks will appear in 2 to 3 years. Quality problems such as seam degumming and bulging

[0005] 3. The construction period is long, and the material itself determines that the base surface needs to be completely dry (moisture content is not more than 10%) before it can be used after the laying is completed. Greater than the height difference of 0.2mm, it will prolong the construction period

[0006] 4. The manufacturing process still adopts the rubber product production process, the process is complicated, and vulcanization is required, resulting in serious pollution in the production process. After the runway is laid, it needs to be naturally deodorized before it can be used

[0007] 5. Due to the distribution of many pores on the track or sports field, it is difficult to clean after long-term use, and it is easy to breed bacteria. Direct skin contact is unhygienic
