Problems solved by technology

Yet this explosion-proof boot is owing to be provided with plastic steel plate, thus quality is heavy, and steel plate can not be discounted, and wearing is inconvenient, and comfort is relatively poor, has brought inconvenience to the personnel working in the field for a long time; In addition, this explosion-proof boot TPU layer and front Between the plastic steel plate for the palm protection and the plastic steel plate for the heel protection, and between the composite anti-stab layer and the plastic steel plate for the forefoot protection and the plastic steel plate for the heel protection, there are weak points of poor bonding strength (the plastic steel plate and other materials are not easy to fit), and the bottom each Inadequate bonding between layers affects wear and functionality
Because TPU is not resistant to high temperatures, when the TPU foam layer encounters a landmine explosion, the high temperature generated by the explosion can easily melt the TPU, changing the entire bottom of the shoe and weakening the protective performance
Because the bottom of the shoe is relatively thick and not easy to bend, it can only have the function of explosion-proof

Embodiment 1

[0069] Example 1 A multifunctional lightning protection and explosion-proof boot

[0070] This embodiment is a multifunctional lightning protection and explosion-proof boot, which includes an upper made of an integrally connected upper and a sole.

[0071] Such as figure 1 As shown, the sole is a composite layer structure. The sole consists of a solid rubber layer 1, a foam rubber layer 2, a high-strength aramid composite layer 4, and an aramid composite inner bottom layer 5 from bottom to top. The thickness of the high-strength aramid composite layer 4 is The thickness of the aramid composite inner bottom layer 5 is 3 mm. The aramid composite cloth used in the high-strength aramid composite layer 4 and the aramid composite inner bottom layer 5 is mainly made of aramid cloth, glass fiber cloth, and high-strength fiber polymer sheet bonded by existing resin and adhesive. Commercial purchase, such as through the manufacturer for Jiangsu Jurong Tianhe Shoes Co., Ltd. to purchase.

Embodiment 2

[0078] Example 2 Preparation process of multifunctional lightning protection and explosion-proof boots

[0079] This embodiment is the preparation process of the multifunctional lightning protection and explosion-proof boots in the above-mentioned embodiment 1. It is produced in the following sequence of steps:

[0080] (A1) Cutting of upper and sole material

[0081] Cut the upper and sole materials separately according to the model, and set aside after shaping;

[0082] (B1) Making shoe uppers

[0083] ①Sew the parts of the shoe upper, and apply 108 powder glue to the bonding parts of the waterproof surface skin layer 7 and the aramid composite layer 10 of the shoe upper, respectively, and place them in an oven to dry at 50°C for 4 minutes. Glue the two stations and parts, get a1;

[0084] ②Sew the aramid composite layer 10 of a1 and the polyester composite layer 11 to obtain b1;

[0085] ③ Bind b1 to the eyelet and shoe loop to obtain the upper c1;

[0086] (C1) Shoe molding

[0087] ①F...

Embodiment 3-6

[0100] Example 3-6 Preparation process of multifunctional lightning protection and explosion-proof boots

[0101] Examples 3-6 are a preparation process of the multifunctional lightning protection and explosion-proof boots provided in Example 1. The preparation process is similar to that of Example 2, except that the corresponding technical parameters in the preparation process are different. The results are shown in the table below.

[0102] Table 1 Technical parameters in the preparation process

[0103]

[0104] The preparation process of the above-mentioned embodiment is simple and easy to control. The multifunctional lightning protection and explosion-proof boots have good lightning protection and explosion-proof effects and also have waterproof and flame-retardant properties. The layers of the shoes are firmly bonded and have a long life. It provides substantial protection against high-speed debris, wreckage and hot air currents produced by anti-personnel landmines with a cert...

Abstract

The invention discloses a multifunctional anti-thunder and anti-explosion boot. The multifunctional anti-thunder and anti-explosion boot comprises a shoe upper made of an integrally-connected vamp and a shoe sole. The shoe sole sequentially comprises a solid rubber layer, a foaming rubber layer, a high-strength aramid fiber composite layer and an aramid fiber composite inner bottom layer from bottom to top. The vamp sequentially comprises a waterproof surface layer, an aramid fiber composite layer and a dacron composite layer from outside to inside. The boot is light in weight and has the anti-thunder function, the anti-explosion function, the waterproof function and the fire resistance, and a worker can lightly and comfortably wear the boot. The invention further provides a making technology of the multifunctional anti-thunder and anti-explosion boot. The making technology includes the steps of cutting vamp materials and shoe sole materials, making the shoe upper, forming the boot and the like. The making technology of the boot is simple and easy to control; the layers of the made boot are firmly combined, the service life is long, and the protection effect is good. The making technology is suitable for making the anti-thunder and anti-explosion boot, the made boot is further applied to a mine clearance sapper, an explosive removal expert and a fire protection and special operation person in the outdoor and special environments.

Description

Technical field [0001] The invention belongs to the field of shoemaking, and relates to a shoe boot and a preparation process thereof, in particular to a multifunctional lightning protection and explosion-proof boot and a preparation process thereof. Background technique [0002] Traditional lightning protection and explosion-proof shoes and boots mostly use steel, plastic steel, glass fiber or aramid as the upper or sole material, which is processed into boots through a certain process. However, this kind of explosion-proof footwear only has a single protective performance, such as only lightning protection performance or only explosion-proof performance; in addition, the use of steel plate, plastic steel or glass fiber in the production of shoes and boots makes the shoes heavy and heavy , It is not easy to bend, and it is inconvenient for people to wear and walk, which increases the burden on the wearer. [0003] The Chinese invention patent application with application number 2...
