Embodiment 1

[0018] The inner surface of the pores of the polyurethane sponge of the present invention is covered with a layer of hydrophobic layer, and the hydrophobic layer in this embodiment is a layer of polydimethylsiloxane. The production method includes: first, polydimethylsiloxane is added to the raw material components of the polyurethane sponge; then, the anti-siphon polyurethane sponge is produced according to the normal sponge foaming process, which has the functions of anti-siphon and air permeability, and can ensure its The various products produced will not have unpleasant odors caused by the inhalation of human sweat into the products, and will not affect the service life of the shoes. The weight ratio of water to polydimethylsiloxane in the raw material of the polyurethane sponge component is 4:1. Of course, an anti-mildew and anti-bacterial agent can also be mixed with the raw material components of the polyurethane sponge to achieve anti-mildew and anti-bacterial effects...

Embodiment 2

[0020] The inner surface of the pores of the polyurethane sponge of the present invention is covered with a layer of hydrophobic layer, and the hydrophobic layer in this embodiment is a layer of polydimethylsiloxane. The production method includes: first, polydimethylsiloxane is added to the raw material components of the polyurethane sponge; then, the anti-siphon polyurethane sponge is produced according to the normal sponge foaming process, which has the functions of anti-siphon and air permeability, and can ensure its The various products produced will not have unpleasant odors caused by the inhalation of human sweat into the products, and will not affect the service life of the shoes. The weight ratio of water to polydimethylsiloxane in the polyurethane sponge component raw material is 6:1. Of course, an anti-mildew and anti-bacterial agent can also be mixed with the raw material components of the polyurethane sponge to achieve anti-mildew and anti-bacterial effects.

Embodiment 3

[0022] The inner surface of the pores of the polyurethane sponge of the present invention is covered with a layer of hydrophobic layer, and the hydrophobic layer in this embodiment is a layer of polydimethylsiloxane. The production method includes: first, polydimethylsiloxane is added to the raw material components of the polyurethane sponge; then, the anti-siphon polyurethane sponge is produced according to the normal sponge foaming process, which has the functions of anti-siphon and air permeability, and can ensure its The various products produced will not have unpleasant odors caused by the inhalation of human sweat into the products, and will not affect the service life of the shoes. The weight ratio of water to polydimethylsiloxane in the raw material of the polyurethane sponge component is 8:1. Of course, an anti-mildew and anti-bacterial agent can also be mixed with the raw material components of the polyurethane sponge to achieve anti-mildew and anti-bacterial effects...

Abstract

The polyurethane sponge has one hydrophobic layer covering the inner surfaces of its pores, and thus has siphon resisting effect. The product made with the polyurethane sponge has no sweat sucked into the inside, so that it has no bad smell and long service life.

Description

technical field [0001] The invention relates to a polyurethane sponge and a production method thereof. Background technique [0002] In modern society, the application of polyurethane sponge is becoming more and more important in people's daily life. Polyurethane sponge can be widely used in shoes and hats, toys, furniture, children's products, pet products, etc. Especially now the use of polyurethane sponge in footwear is increasing. However, the existing shoes made of polyurethane sponge, when people walk on the feet, the feet are prone to sweat due to the high temperature inside the shoes, and the sweat will be absorbed into the shoes due to the siphon phenomenon of the polyurethane sponge. In the environment, it is easy to breed bacteria, mold and so on. Like this, not only can make shoe appear unpleasant smell, and can influence the service life of shoe. [0003] Therefore, be necessary to invent a kind of novel polyurethane sponge, do not produce siphon phenomenon, ...
