Thermochromic TPE material capable of emitting light at night

Abstract

The invention discloses a thermochromic TPE material which can be used for a plastic coating layer in a wire and can emit light at night. The TPE material comprises the following raw material components in parts by weight: 10-50 parts of styrene-butadiene segmented copolymer; 5-20 parts of white mineral oil; 5-30 parts of polypropylene; 5-30 parts of calcium carbonate; 5-30 parts of polyolefin resin; 1-20 parts of fluorescent powder; 0.5-5 part of thermochromic powder, wherein the thermochromic powder is prepared from the following raw material components: 10-30 parts of melamino-formaldehyderesin, 3-15 parts of styrene-maleic anhydride copolymer, 30-50 parts of methyl stearate, 5-20 parts of ethyl stearate and 1-8 parts of uranidin-37. The fluorescent powder absorbs light under the irradiation of light in the daytime and emits fluorescence at night, and meanwhile, the color of the thermochromic powder added into the TPE can be changed along with the change of temperature, so that thecolor of the thermochromic powder can be changed after the outdoor temperature is reduced at night, the color of the fluorescence can also be correspondingly changed, and a user is reminded of the temperature change.

Description

Technical field: [0001] The invention relates to the technical field of wire materials, in particular to a temperature-sensitive and color-changing TPE material that can be used for the night-time luminescence of the plastic coating layer in the wire. Background technique: [0002] Wires (such as wires, wires, cables, etc.) are used in a wide range of applications, and the most common wire is a core wire (wire) covered with a plastic protective layer. The wires used in the current digital products such as headphone cables generally use TPE materials, which have better elasticity and aging resistance than traditional rubber materials, and are easy to process and easy to extrude, which is conducive to the production of wires. So it is widely used in wire. [0003] General TPE wires are mainly made of styrene-based materials, such as styrene-butadiene block copolymers, whose performance is close to that of SBR rubber. It is a conventional material for making plastic layers of...

Problems solved by technology

However, the current products of this type only consider the characteristics of the wire itself such as aging resistance and elasticity, and lack other aspects of research.

For example, the current TPE wire cannot realize the characteristics of nighttime luminescence while sensing temperature, etc., the inventor formally proposes the following technical solution based on this
