Problems solved by technology

However, the pavement coils currently used in the market have problems of durability and unsuitable adhesives, and quality problems such as surface cracking, joint degumming, and bulging will appear in 2 to 3 years; and the construction must wait until the base surface is completely dry ( Moisture content is not more than 10%), and the flatness is not more than 0.2mm in height difference, which will seriously affect the construction progress; in addition, the manufacturing process still adopts the rubber product production process, which has complicated procedures and serious pollution

Abstract

The invention relates to a novel thermoplastic elastomer composite self-adhesion sport field paving coiled material. The coiled material comprises a main body layer made of thermoplastic elastomer, wherein a creep deformation self-adhesion layer is arranged on the bottom surface of the main body layer, and the thermoplastic elastomer is prepared by blending and modifying ethylene propylene diene monomer rubber and polyolefin resin. The manufacture process comprises the steps of: blending the ethylene propylene diene monomer rubber, the polyolefin resin and naphthenic oil in proportion, and carrying out twin-screw extrusion, so as to obtain the thermoplastic elastomer; adding an assistant agent and the naphthenic oil, heating and carrying out high-speed stirring and blending, carrying out compound extrusion by utilizing a pin extruder, then carrying out knurling, overlap edge profiling, microwave foaming, vulcanizing and double-roll gluing, and carrying out crimping to prepare the novel thermoplastic elastomer composite self-adhesion paving coiled material after cooling. According to the novel thermoplastic elastomer composite self-adhesion sport field paving coiled material, the shortage of the prior art can be improved, the performance index of the product is improved, and the manufacture process is simple; the controllable thickness is 4-13mm, and the novel thermoplastic elastomer composite self-adhesion sport field paving coiled material is mainly applied to the fields of athletic tracks in sport fields, basketball courts, tennis courts, badminton courts and the like.

Description

technical field [0001] The invention relates to a novel thermoplastic elastomer composite self-adhesive sports field pavement coil and its manufacturing process, which belongs to the coil processing field. technical background [0002] At present, the roll material used for paving sports venues and public venues at home and abroad is a composite rubber or a composite material of rubber and plastic. It is mainly used for ground paving in public places with protective requirements such as runways, stadiums, and kindergartens. However, the pavement coils currently used in the market have problems of durability and unsuitable adhesives, and quality problems such as surface cracking, joint degumming, and bulging will appear in 2 to 3 years; and the construction must wait until the base surface is completely dry ( The moisture content is not more than 10%), and the flatness is not more than 0.2mm in height difference, which will seriously affect the construction progress; in addi...
