Abstract

The invention discloses a negative ion dispersion type color changing EVA elastic composite material. The material comprises the following components by mass: 320-430 parts of functionally modified filler material, 20-100 parts of temperature control material, 290-350 parts of matrix resin, 50-100 parts of nucleating flame retardant, 50-100 parts of dispersing agent, 50-60 parts of color master batch powder, 30-50 parts of flexible agent, 50-150 parts of bactericidal flavoring agent and 30-80 parts of photo-induced organic color changing agent. Due to the ring vermiculite component, negative ions can be released to remove toxic and harmful gases such as formaldehyde, benzene, xylene and VOC in the air in the space. Due to the ring vermiculite component, the composite material can emit farinfrared rays with the wavelength similar to that emitted by the human body, a resonance effect can be generated and is beneficial to human microcirculation, and the composite material can be used asa bactericidal anti-inflammatory material in medical treatment.

Description

technical field [0001] The invention relates to the technical field of special plastic materials, in particular to an anion-diffusing fragrance-type color-changing EVA elastic composite material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is the fourth largest ethylene series copolymer after HDPE, LDPE and LLDPE, and is also the most important ethylene random copolymer developed in recent years. resin. In EVA materials, along with the increase of its contained vinyl acetate (VA) components, its elasticity, softness, adhesion, compatibility, transparency and solubility and other properties are also improved accordingly. According to the size of its VA mass fraction components, it can be subdivided into three categories: among them, the VA content is 5% to 40%, which is generally called EVA resin, which is mainly used to modify polyethylene and make electric wires. Cable materials, films, and other molding products a...
