Problems solved by technology

But in these applications, the luminous material is used as a kind of paint or mixed into the paint. There is only a thin layer on the surface of the object, which is easy to fall off and has a short service life.
In composite materials, there are many factors that affect the luminous intensity and afterglow time of luminous materials. A certain substance in the formula or a certain process in the processing process may have a quenching effect. At present, few people have studied the direct addition of luminous materials to shoes. Influencing factors in material formulation

Embodiment 1

[0045] In this embodiment, the EVA luminous shoe material is composed of the following components by weight:

[0046] EVA 40W 40 parts, EVA 5110J 10 parts, ethylene-octene copolymer (POE) 8540 21 parts, sarin resin 8940 18 parts, luminous powder 12 parts, mineral oil 3 parts, AC foaming agent 2.8 parts, crosslinking agent 2 parts of BIBP, 1.8 parts of zinc stearate, 7 parts of stearic acid, and 3 parts of nano-silica.

[0047] First mix other raw materials except crosslinking agent BIBP and AC foaming agent for banburying, adjust the banburying temperature to 98°C, keep it for 5 minutes, then add crosslinking agent BIBP and AC foaming agent, continue banburying and raise the temperature , the discharge temperature is 110°C. After the banburying is completed, the refining and granulation are carried out to obtain the EVA luminous rice, and then the EVA luminous rice is put into the hopper of the injection machine, and the temperature is controlled at 178 degrees after one injec...

Abstract

The invention discloses an EVA luminous shoe material and a preparation method thereof, the EVA luminous shoe material is obtained by banburying, milling and granulating a raw material EVA, an ethane-octylene copolymer (POE), surlyn, noctilucent powder, mineral oil, an AC foaming agent, a cross-linking agent BIBP, zine stearate, stearic acid, and nano white carbon black to prepare the EVA luminous shoe material granules, and the luminous shoe material granules are performed with injection moulding at once to obtain the EVA luminous shoe material. When the luminous shoe material does not foam, the light transmittance is good, haze is moderate, and the luminous shoe material is suitable for various shoe fittings and waistline substrates, has the characteristics of low density, high rebound and good mechanical property after the luminous shoe material foams, and the luminous shoe material is especially suitable for waistline for sport shoes, leisure shoes and dance shoes. The continuous luminescence time of the luminous shoe material exceeds 12 hours, and the luminous shoe material has the obvious characteristics of no requirement of power supply, overnight luminescence, energy saving and environmental protection, and has good market prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an EVA luminous shoe material and a preparation method thereof. Background technique [0002] Luminescent material, a kind of photoluminescent material, is a kind of material that can absorb excitation light energy (sunlight or light) and store it. After the excitation light source is removed, the stored energy is slowly released in the form of light. The whole process A luminous material that can last for several or even dozens of hours. Luminous materials can repeat the process of absorbing light-emitting-storage-re-emitting light without consuming electric energy. It is a kind of energy storage and energy-saving "green" luminescent material. field. However, in these applications, the luminous material is used as a kind of paint or mixed into the paint. There is only a thin layer on the surface of the object, which is easy to fall off and has a short ser...
