Environment-friendly high-performance thermoplastic elastomer coiled material and manufacturing process thereof

Abstract

The invention provides an environment-friendly high-performance thermoplastic elastomer coiled material and a manufacturing process thereof. The manufacturing process comprises the following steps: oxidization of asphalt to a softening point of 80 to 90 DEG C; metering and conveying of the asphalt to a material mixing tank; heating to about 240 DEG C; addition of 20 to 40% of talcum powder, wherein the talcum powder is a filling material used for improving stability of heat and atmosphere, and the softening point is increased by 1 DEG C when every 5% of talcum powder is added; uniform stirring in the material mixing tank until surface bubbles disappear; heat preservation of a cementing material and standing of the cementing material for subsequent usage; addition of the cementing material (wherein the dip-coating amount of the cementing material is controlled by using a roller press) and carcass into a dip-coating pool with a temperature of 180 to 220 DEG C; spreading of sand with a spreader; compaction; metering; cooling; storage; rolling; packaging; and warehousing. The process provided by the invention can overcome disadvantages of the prior art, improves the performance indexes of the product and is simple. The novel thermoplastic elastomer composite self-adhesive coiled material applied to paving of sport fields can be controlled at a thickness of 4 to 13 mm and is mainly used for places like tracks of sport fields, basketball courts, tennis courts and badminton courts.

Description

1. Technical field [0001] The invention relates to an environment-friendly and high-performance thermoplastic elastomer coil and a manufacturing process thereof, belonging to the coil processing field. 2. Background technology [0002] The structure of the surface layer of the runway in the track and field field develops from the soil layer to the mixed layer of cinder, lime and clay. With the development of science and technology, plastic runways appeared in the early 1960s. In the 1980s, the radius of the track track curves was from 36 meters to 37.898 meters, and then developed to 36.50 meters. Experience has shown that most 400-meter semi-circular tracks are built with a radius of 35 meters to 38 meters, and the IAAF proposes to build a track with a radius of 36.50 meters as much as possible. The above-mentioned three kinds of runways with different radii are called "400-meter standard semi-circular track and field". At present, the used venues of various track and fie...

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 ( 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 addition, the manufacturing process still adopts the rubber product production process, the process is complicated and the pollution is serious
