Problems solved by technology

[0003] Common rubber runway materials in the prior art are prefabricated rolls produced from ordinary natural rubber and synthetic rubber (styrene butadiene rubber, butadiene rubber). And part of the material heavy metals and organic volatiles exceed the standard, which seriously endangers human health. At present, the rubber runway coils on the market have poor durability, short service life, poor wear resistance, tensile strength and elasticity, and are not environmentally friendly. Meet the paving requirements of high-end gymnasiums, track and field and other indoor and outdoor venues

Abstract

The invention discloses an environment-friendly rubber prefabricated track coiled material and a preparation method thereof, and relates to the technical field of track coiled materials. The rubber prefabricated track coiled material is mainly prepared from the following raw materials in parts by weight: 30 to 60 parts of ethylene propylene rubber, 40 to 80 parts of reclaimed rubber, 20 to 50 parts of an LLDPE and HDPE blend, 1 to 30 parts of a nanometer rare earth oxide, 5 to 10 parts of a vulcanizing agent, 6 to 12 parts of paraffin oil, 10 to 15 parts of naphthenic oil, 1 to 5 parts of zincoxide and 50 to 200 parts of a filler, wherein the reclaimed rubber is a mixture of butyronitrile reclaimed rubber and butyl chloride reclaimed rubber, and the mass ratio of the butyronitrile reclaimed rubber to the butyl chloride reclaimed rubber is 2: (0.5 to 1). The environment-friendly rubber prefabricated track coiled material solves the problem that a rubber track coiled material is low inabrasive resistance, tensile strength and elasticity and not environmentally friendly at present, the obtained rubber prefabricated track coiled material is excellent in physical and mechanical performances and has excellent tensile strength and abrasive resistance, the product is free of noxious substance residue, and the recycled reclaimed rubber is cost-saving, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of runway coils, in particular to an environment-friendly rubber prefabricated runway coil and a preparation method thereof. Background technique [0002] The plastic runway can be applied to the pavement of various gymnasiums, track and field fields and other indoor and outdoor venues. The prefabricated rubber runway is generally divided into three layers according to the function, the wear-resistant and flexible surface layer, the pressure buffer bottom layer and the adhesive layer of the prefabricated rubber runway roll material and the runway foundation. The coefficient of friction with the ground can transmit pressure, so the surface layer is generally made of high-density rubber rolls to roll out a specific fine anti-vertigo pattern. The main function of the bottom layer is to rely on its own elastic characteristics to absorb the buffer from the surface layer. Pressure, the bottom layer is generally c...
