Problems solved by technology
At present, for plastic runway particles, some particles with better quality use EPDM rubber in combination with a large amount of fillers and plasticizers to reduce their cost while ensuring their elasticity. Its tearing and compression permanent deformation and dyeing are poor, and there will be problems such as agglomeration and slag during storage
Most of the "poisonous particles" reported in the news are waste tires, discarded cables, and various rubber wastes of unknown origin and species, which are obtained by simple crushing. Such particles are cheap and have a pungent smell. Toxic substances that emit slowly will cause great harm to people's health

Embodiment 1-3
[0032]
[0033] The preparation method of embodiment 1-3 is as follows:
[0034] 1) Take the weight of various required materials according to the requirements of the formula;
[0035] 2) The temperature of the internal mixer is set at 120°C, and the rubber and plastic elastomer, stabilizer, filler, plasticizer, anti-aging agent, active agent, foaming agent, and pigment are put into the internal mixer in sequence, mixed for 8 minutes, and the Material, next piece, get mixed rubber.
[0036] 3) Put the mixed rubber into the open mill for refining, and press the mixed rubber into tablets after 5 minutes;
[0037] 4) Put the mixed film into the extruder and extrude it into a rubber sheet. The temperature of the extruder is 80-120°C, and the thickness of the rubber sheet is 6mm.
[0045] The preparation method of embodiment 4-6 is as follows:
[0046] 1) Take the weight of various required materials according to the requirements of the formula;
[0047] 2) The temperature of the internal mixer is set at 120°C, and rubber-plastic elastomers, stabilizers, fillers, plasticizers, anti-aging agents, and pigments are put into the internal mixer in sequence, mixed for 8 minutes, discharged, and released to obtain a mixed product. Rubber mixing.
[0048] 3) Put the mixed rubber into the open mill for refining, and press the mixed rubber into tablets after 5 minutes;
[0049] 4) Put the mixed film into the extruder and extrude it into a rubber sheet. The temperature of the extruder is 80-120°C, and the thickness of the rubber sheet is 6mm.
[0050] 5) Send the extruded rubber sheet into the electron accelerator irradiation room for irradiation cross-linking, and the irradiation dose is 65kGy.
[0051] 6) After cutting the cross-linked rubber sheet...

Abstract
The invention discloses a preparation method of high-elastic environment-friendly plastic runway particles. The preparation method is characterized in that according to the formula, the particles comprise the following components in parts by weight: 100 parts of a rubber and plastic elastomer, 3-6 parts of a stabilizer, 40-300 parts of filler, 0-60 parts of a plasticizer, 1-3 parts of an anti-ageing agent, 0-1 part of an activator, 0.2-3 parts of a foamer and 1-6 parts of a pigment. The preparation method comprises the following steps: (1) weighing raw materials; (2) successively adding the raw materials into an internal mixer to mix; (3) refining the raw materials in an open mill and tailoring; (4) inputting the sizing material into an extruder to extrude a panel; (5) carrying out radiation crosslinking; (6) crushing the panel to obtain particles; (7) chemically or physically foaming the particles; and (8) carrying out examination and packaging to obtain a finished product. The particles are good in elasticity, ageing resistance and coloring property and free from toxicity and environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of plastic runways, in particular to a formula and process for preparing environmentally friendly plastic runway granules. Background technique [0002] The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, stable physical properties, and anti-skid. A more comfortable sports field reduces the rate of falls. In the past one or two years, schools in many places across the country have issued a cry of "smell runway, smelly playground", which has made people pay more attention to the safety and environmental protection of plastic runways. At present, for plastic runway particles, some particles with better quality use EPDM rubber in combination with a large amount of fillers and plasticizers to reduce their cost while ensuring their elasticity. Its tearing and compression permanent deformation and dyeing are poor, and there will be problems...
