Embodiment 1

[0029] Such as figure 1 Shown, a kind of preparation method of puncture-resistant breathable sole comprises the following steps:

[0030] S1: Dissolve aluminum nitrate and malic acid in deionized water and heat up to 85°C, then add spinning additive PVP and stir for 12 minutes, then add acrylic resin and carbon nanotubes to it, and heat to After treatment at 100°C, ultrasonically stir for 2 hours, then concentrate the mixed solution and cool it to room temperature to obtain a spinning solution;

[0031] S2: The spinning solution is processed by a centrifugal spinning machine, and centrifugally spun at 2000 rpm and 65°C, and then the spun fibers are dried in an oven at 60°C for 18 hours, and then sintered at 1200°C for 1 hour to obtain composite fibers;

[0032] S3: Mix and heat polyol, catalyst, foaming agent, carbon fiber powder, chain extender, foam stabilizer and composite fiber to 110°C, then add isocyanate and diffuse by ultrasonic for 2 hours, and pour into different mo...

Abstract

The invention discloses a preparation method of an anti-puncture breathable sole, and belongs to the technical field of labor protection articles. The preparation method is characterized in that: composite fibers are firstly formed, carbon nanotubes are contained in the composite fibers, the carbon nanotubes are evenly distributed in a net-shaped structure formed by acrylic resin under the actionof ultrasonic dispersion, and therefore the prepared composite fibers are high in tensile strength and good in bending toughness; and after molding, the sole has an extremely strong anti-puncture effect, a honeycomb foaming body integrally molded by foaming is arranged between the outsole and the midsole, and the honeycomb foaming body is exposed on the surface of the midsole and the side surfaceof the outsole, so that after the safety shoe is manufactured, air in the shoe can be ventilated and dissipated through the honeycomb foaming body, and when the midsole is subjected to the action force of stepping, the honeycomb foaming body can improve the wearing flexibility of the sole, and meanwhile, the puncture resistance is not influenced.

Description

technical field [0001] The invention discloses a preparation method of a puncture-resistant breathable sole and labor insurance shoes with the sole, belonging to the technical field of labor insurance production. Background technique [0002] At present, the soles of finished shoes are usually composed of rubber and plastic outsoles, midsoles and insoles, which do not have puncture resistance. However, in some special environments, such as mines, earthquake relief, jungle exploration, army training and combat, etc., the soles are required to have certain puncture resistance, so as to prevent sharp objects such as bamboo sticks and steel nails from penetrating the soles and causing injuries. foot. In order to make the finished shoes have puncture-resistant properties, materials such as steel plates, aramid fiber, and glass fiber cloth are usually used to make puncture-resistant midsoles, so as to ensure the puncture-resistant effect of the soles. The prior art discloses a p...
