Example Embodiment

[0024] Example 1

[0025] The invention discloses a high-performance body armor, which comprises a body armor body. The body armor body is filled with a body armor layer. The body armor layer is composed of a polyurethane film layer and an ultra-high molecular weight polyethylene fiber cloth layer. The polyurethane film layer is located on the upper part of the ultra-high molecular weight polyethylene fiber cloth layer, and the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer are connected to each other by a hot pressing process.

[0026] Further, the ultra-high molecular weight polyethylene fiber cloth layer is composed of an ultra-thin film made of water-based polyurethane resin and polyethylene fibers, and the ultra-thin film occupies 20% of the polyethylene fiber by mass.

[0027] Further, the hot pressing temperature of the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer is 130 degrees, and the body armor layer is provided with 20 groups.

[0028] This application also provides a method for preparing high-performance body armor, including the following steps:

[0029] 1) A film made of water-based polyurethane emulsion and ultra-high molecular weight polyethylene fiber are laminated at a temperature of 130 to make a body armor material;

[0030] 2) Weaving the special ultra-high molecular weight polyethylene fiber made in step 1);

[0031] 3) Hot press the polyurethane film and the polyethylene fiber cloth made in step 2) to make a basic layer of body armor;

[0032] 4) Prepare 20 groups of basic materials for the body armor made in step 3), heat and press the 20 layers together to make body armor cloth, after cooling, select the inner layer, and bond the inner layer and the body armor cloth Sewn into a body armor.

[0033] Further, in the step 1), a hot press is used for continuous hot pressing.

[0034] Further, in the step 2), a loom is used for weaving work.

[0035] Further, in the step 4), a cooling fan is used for cooling, and the cooling time is 20 minutes.

[0036] Further, in the step 4), polyester fabric is selected for the inner layer.

Example Embodiment

[0037] Example 2

[0038] The invention discloses a high-performance body armor, which comprises a body armor body. The body armor body is filled with a body armor layer. The body armor layer is composed of a polyurethane film layer and an ultra-high molecular weight polyethylene fiber cloth layer. The polyurethane film layer is located on the upper part of the ultra-high molecular weight polyethylene fiber cloth layer, and the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer are connected to each other by a hot pressing process.

[0039] Further, the ultra-high molecular weight polyethylene fiber cloth layer is composed of an ultra-thin adhesive film made of water-based polyurethane resin and polyethylene fibers, and the ultra-thin adhesive film accounts for 23% of the polyethylene fiber by mass.

[0040] Further, the hot pressing temperature of the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer is 133 degrees, and the body armor layer is provided with 25 groups.

[0041] This application also provides a method for preparing high-performance body armor, including the following steps:

[0042] 1) A film made of water-based polyurethane emulsion and ultra-high molecular weight polyethylene fiber are laminated at a temperature of 134 to make a body armor material;

[0043] 2) Weaving the special ultra-high molecular weight polyethylene fiber made in step 1);

[0044] 3) Hot press the polyurethane film and the polyethylene fiber cloth made in step 2) to make a basic layer of body armor;

[0045] 4) Prepare 25 groups of one layer of basic material for the body armor made in step 3), heat and press the 25 layers together to make body armor cloth, after cooling, select the inner layer, and bond the inner layer and the body armor cloth Sewn into a body armor.

[0046] Further, in the step 1), a hot press is used for continuous hot pressing.

[0047] Further, in the step 2), a loom is used for weaving work.

[0048] Further, in the step 4), a cooling fan is used for cooling, and the cooling time is 23 minutes.

[0049] Further, in the step 4), polyester fabric is selected for the inner layer.

Example Embodiment

[0050] Example 3

[0051] The invention discloses a high-performance body armor, which comprises a body armor body. The body armor body is filled with a body armor layer. The body armor layer is composed of a polyurethane film layer and an ultra-high molecular weight polyethylene fiber cloth layer. The polyurethane film layer is located on the upper part of the ultra-high molecular weight polyethylene fiber cloth layer, and the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer are connected to each other by a hot pressing process.

[0052] Further, the ultra-high molecular weight polyethylene fiber cloth layer is composed of an ultra-thin adhesive film made of water-based polyurethane resin and polyethylene fibers, and the ultra-thin adhesive film accounts for 25% of the mass fraction of the polyethylene fibers.

[0053] Further, the hot pressing temperature of the polyurethane film layer and the ultra-high molecular weight polyethylene fiber cloth layer is 135 degrees, and the body armor layer is provided with 30 groups.

[0054] This application also provides a method for preparing high-performance body armor, including the following steps:

[0055] 1) A film made of water-based polyurethane emulsion and ultra-high molecular weight polyethylene fiber are laminated at a temperature of 136 to make a body armor material;

[0056] 2) Weaving the special ultra-high molecular weight polyethylene fiber made in step 1);

[0057] 3) Hot press the polyurethane film and the polyethylene fiber cloth made in step 2) to make a basic layer of body armor;

[0058] 4) Prepare 30 groups of basic materials for the body armor made in step 3), heat and press the 30 layers together to make body armor cloth, after cooling, select the inner layer, and glue the inner layer and the two groups of body armor cloth Sew after closing to make body armor.

[0059] Further, in the step 1), a hot press is used to perform the pressing work.

[0060] Further, in the step 2), a loom is used for weaving work.

[0061] Further, in the step 4), a cooling fan is used for cooling, and the cooling time is 25 minutes.

[0062] Further, in the step 4), polyester fabric is selected for the inner layer.
