Weather-resistant soft floor polypropylene special material and preparation method thereof

Abstract

The invention discloses a weather-resistant soft floor polypropylene special material and a preparation method thereof. The weather-resistant soft floor polypropylene special material comprises the following components: polypropylene resin, a thermoplastic polyester elastomer, a compatilizer, an anti-aging aid and a processing aid. The low-hardness and high-modulus special elastomer TPEE is introduced on the basis of a polypropylene material so that the compatibility problem and the common weather resistance problem of the PP material are solved, and a brand new alloy material is obtained. By adding the TPEE, on one hand, the prepared PP material is softer, on the other hand, the PP material has better elastic modulus and surface hardness, and when the weather-proof soft floor polypropylene special material is applied to a sports field, better sports experience can be provided for athletes.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-modulus weather-resistant soft floor polypropylene special material and a preparation method thereof. Background technique [0002] The assembled suspended floor is mainly used in outdoor basketball courts, badminton courts, kindergarten venues, etc. The current assembled suspended floor is mostly realized by weather-resistant polypropylene (PP), or weather-resistant polyethylene (PE) or thermoplastic polyurethane elastomer (TPU). [0003] At present, the PP material has the advantage of good resilience of the ball because the surface Shore hardness D is about 90, but because it is too hard, it has poor impact absorption. The selection of weather-resistant PE will also cause the problem that the sports field is too hard. Although the sports field using TPU has the advantage of impact absorption and good texture, due to the low modulus, the rebound of the ball i...
