Embodiment 1

[0052] Embodiment 1: a kind of colored ETPU sole, its raw material comprises the component of following parts by weight:

[0053] 10 parts of isophorone diisocyanate;

[0054] 20 parts of polyester polyol;

[0055] 20 parts of polyether polyols;

[0056] 2 parts of chain extender;

[0057] 1 part of white carbon black;

[0058] 1 part of masterbatch mixture with at least two different colors; among them, the polyester polyol is polyethylene adipate diol, the polyether polyol is polytetrahydrofuran ether diol, and the chain extender is ethylene glycol .

[0059] The color masterbatch mixture includes 1 part of color masterbatch a and 1 part of color masterbatch b. The components of color masterbatch a and their corresponding parts by weight are shown in Table 1, wherein the pigment is carbon black, and the dispersant is Polyacrylamide, the heat stabilizer includes calcium zinc composite heat stabilizer and calcium stearate with a weight ratio of 1:1, the light stabilizer i...

Abstract

The invention discloses a colored ETPU shoe sole and a preparation method thereof, relating to the technical field of shoe sole materials. The colored ETPU shoe sole contains the following raw material components in parts by weight: 10-20 parts of isophorone diisocyanate, 20-40 parts of polyester polyol, 10-20 parts of polyether polyol, 2-5 parts of a chain extender, 1-5 parts of white carbon black and 1-2 parts of a mixture of at least two color master batches with different colors, wherein the color master batches contains the following raw material components in parts by weight: 25-30 partsof TPU, 30-50 parts of pigments, 1-5 parts of a dispersing agent, 0.5-1.5 parts of a heat stabilizer, 0.5-1.5 parts of a light stabilizer, 10-20 parts of a filler, 6-8 parts of a compatilizer and 6-10 parts of a lubricant. By adding pigments and the compatilizer into the base material of TPU, the consistency of the pigments is increased; by adding the dispersing agent, the dispersity of the pigments is improved; by utilizing the heat stabilizer and the light stabilizer, the photo-thermal oxidation of a benzene ring structure of polyurethane can be resisted, so that the situation that the color of TPU is influenced by the yellowing is avoided; and by utilizing isophorone diisocyanate, the shoe sole is strong in light resistance, heat resistance and oxidation resistance and is unlikely to yellow, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of shoe sole materials, more specifically, it relates to a colored ETPU shoe sole and a preparation method thereof. Background technique [0002] At present, most foaming materials are based on plastic, and a large number of air bubbles are obtained inside the plastic matrix by adding physical or chemical foaming agents. Foamed materials are widely used in daily necessities, packaging and automobiles due to their light specific gravity, heat insulation, shock absorption and sound absorption. Thermoplastic polyurethane (TPU) can be roughly divided into polyester and polyether types. Its hardness range is very wide (50HA-80HD), and it has excellent wear resistance, high mechanical strength, good water resistance, oil resistance and can be melted and recycled. Etc. TPU foam material not only retains the excellent properties of the original matrix material, but also has good resilience, low density and can be ...
