EVA composite material applied to high jump mat and preparation method thereof

Abstract

The invention discloses an EVA composite material applied to a high jump mat and a preparation method thereof. The EVA composite material is prepared from the following components in parts by weight: 40-60 parts of a base material, 5-10 parts of masterbatches serving as a foaming agent, 0.5-1 part of a cross-linking agent, 10-20 parts of elastomers, 1-3 parts of an antibacterial agent, 10-25 parts of carbon black, 10-20 parts of a filler and 0.5-1 part of compound additives, wherein the base material is prepared by mixing an ethylene-vinyl acetate copolymer and polyethylene according to a weight ratio of (70-90) to (10-30); the carbon black is prepared by mixing special conductive carbon black and acetylene carbon black according to a weight ratio of (2-5) to 1; the filler is prepared by mixing organic modified montmorillonite and calcium carbonate according to a weight ratio of 1 to (2-3). The preparation method is simple and is convenient to operate. The invention provides a light, antibacterial and environment-friendly high jump mat; a compound system has the characteristics of static electricity resistance, flame retardance, abrasion resistance, flexibilization and shock absorption, can highly meet requirements of the high jump sport and simultaneously responds to the healthy and safe sport concept.

Description

technical field [0001] The invention relates to the field of sports materials, in particular to an EVA composite material for a high jump mat and a preparation method thereof. Background technique [0002] With the advancement of science and technology, people's living standards are gradually improving, and people's material, spiritual and cultural needs are also constantly improving. At present, sports have become an important part of people's daily life. In order to make people enjoy sports better, safety and health are the most basic guarantees, such as high jump, in addition to a comfortable venue, a qualified mat must also be needed to ensure the safety of athletes. [0003] Commonly used high jump mats are polyurethane foamed plastics or EVA foamed plastics or rubber, etc. During use, it is found that the high jump mats of these materials have certain defects: although the rubber material mat is cheap, it is heavy and inconvenient to move; Although the EVA foamed pla...

Problems solved by technology

[0003] Commonly used high jump mats are polyurethane foamed plastics or EVA foamed plastics or rubber, etc. During use, it is found that the high jump mats of these materials have certain defects: although the rubber material mat is cheap, it is heavy and inconvenient to move; Although the EVA foamed plastic mat has low density, good physical properties, good weather resistance and non-toxicity, its elasticity, tear resistance and peel resistance are not ideal; although polyurethane has good wear resistance, tear resistance and elasticity, its price is low. Higher; and during the exercise, due to the contact between the athlete's sweat and the high jump mat, a large number of bacteria will grow on the surface of the high jump mat, which is not conducive to the health of the athletes
