The runway is simple to make, but the amount of TPU is large. TPU is expensive in the market, and the cost and price of the runway are high. In addition, the talcum powder is flake, and the use of talcum powder as filler has a negative impact on the impact toughness of the runway.
[0007] Generally speaking, the prefabricated runways on the market are either made of more expensive polyurethane glue to bond various particles, mostly EPDM particles, and made into coils. The overall cost of this kind of runway is relatively high, or it is processed with various rubber vulcanization. Formed, its processing is complicated, the production efficiency is low, and the production energy consumption is large
Moreover, both runways use thermosetting materials, which are difficult to recycle after reaching the end of their service life

Abstract
The invention discloses a fully recyclable and environment-friendly thermoplastic prefabricated plastic runway and a preparation method thereof, which is made of the following components by weight: 15-35 parts of thermoplastic elastomer, 10-50 parts of oily filler, and 5 parts of compatibilizing resin ‑15 parts, 20‑80 parts of inorganic powder filler, 2‑15 parts of functional additives, after mixing the components evenly, melt and knead them through a twin-screw extruder, and the evenly kneaded molten material is fed from a flat die It is extruded at the mouth, enters the shape of the twin-roller cooling extrusion shape in the thermoplastic state, and obtains a rough anti-skid pattern and a hollow bottom, and the prefabricated plastic runway after cooling and shape. The polymer materials used in the prefabricated plastic runway of the present invention are all thermoplastic materials, which have the advantages of no odor, good elasticity, high durability, low overall cost, environmental protection, non-toxicity, and full recyclability.
Description
technical field [0001] The invention belongs to the field of plastic runways, and in particular relates to fully recyclable and environment-friendly thermoplastic prefabricated plastic runways and a preparation method thereof. Background technique [0002] In my country, there is nearly 30 million square meters of demand for plastic runways every year. As people's requirements for quality of life rise, prefabricated runways with higher prices and better quality are increasingly favored by the market. [0003] CN104831600A released a non-water-permeable self-knotting plastic runway. The base layer of the main part is made of mixed polyurethane glue, catalyst and black particles, solidified and defoamed. On the base layer is a self-knotting clear slurry layer The main component of these two layers is polyurethane glue. This kind of runway has uniform texture, good wear resistance, no threshing, and long service life, but its polyurethane consumption is large and its cost is h...
