Description

A new type of bulletproof plate

technical field

The utility model patent relates to a bulletproof material board, especially a new type of bulletproof board. The bulletproof board not only has the same bulletproof performance as the traditional bulletproof board, but also has excellent waterproof and aging resistance characteristics, strong adhesion and high production efficiency. .

Background technique

Traditional bulletproof panels are basically composed of bulletproof materials, or at most the outer layer of the bulletproof material is coated with black polyester oxford cloth or polyester knitted fabric and other fabrics, and then the outer protection of the bulletproof panels is completed by bonding. Layer setting, the process is simple, and the added value is not high, and the bulletproof panels produced by the above two process methods still have the following defects:

1) Poor waterproof and aging resistance;

2) All manual operation, low production efficiency, and the appearance of problematic products due to factors such as different operating proficiency;

3) Adhesives need to be coated when Oxford cloth or polyester cloth is bonded to the bulletproof sheet, which is prone to poor bonding fastness and unbonding.

Utility model content

The purpose of the utility model is to provide a new type of bulletproof board, which solves the shortcomings of the traditional bulletproof board such as short service life, large fluctuation of production quality and low production efficiency.

In order to solve the above technical problems, the utility model provides a new type of bulletproof plate, which includes a three-layer structure, and the sequence from the inside to the outside is:

The bulletproof material layer and the outer protective layer also include an interface layer between the bulletproof material layer and the outer protective layer;

As an example, the bulletproof material layer is formed by pressing materials such as polyethylene fiber UD sheet or aramid fiber UD sheet;

As an example, the outer protective layer is made of polyurea coating, polyurethane coating or a mixed coating of polyurea and polyurethane;

As an illustration, the interface layer is made of a primer material suitable for the bulletproof material layer and the outer protective layer material;

As an example, the thickness of the interface layer is 10-15um, which can ensure the best bonding effect and wearer's comfort without adding too much weight.

As an example, the outer surface of the outer protective layer is a granulated structure surface.

A preparation method for a novel bulletproof plate, comprising the following processes:

Compressed film lamination process, cutting sandblasting process, dry grinding process and three-time spraying process;

Specifically, in the actual production process, it is necessary to select an appropriate bulletproof material layer for processing according to different bulletproof levels of protection. As an example,

The "compressing mold closing process" includes: placing the selected bulletproof material layer in a hot press, clamping the mold, the working pressure is 1mpa, starting to heat up from normal temperature, and gradually rising to 120°C, then rising from normal pressure to Press down to 16MPa, keep the temperature and pressure constant under this condition, after 30 minutes of constant temperature and constant pressure, start the cooling operation, and release the mold after cooling down to 60°C;

It has been verified by experiments that this kind of temperature and pressure process can achieve the tightest mold clamping of bulletproof materials, with the best bulletproof performance, and is more suitable for the smooth implementation of the following processes;

The "cutting and sandblasting process" includes: pressing the mold-fitting bulletproof material layer for cutting and trimming, and sandblasting the cut bulletproof material layer, and spraying the surface of the bulletproof material layer on the interface Layer operation, control the thickness of the interface layer to 10-15um, and polish the surface after drying to ensure the surface is smooth;

It has been verified by experiments that this thickness range is most conducive to improving the bonding effect without adding additional burden and manufacturing cost;

The "three-time spraying process" includes: spraying the outer protective layer on the treated plate, setting the heater temperature of the spraying equipment to 70-80°C, setting the heating temperature of the pipeline to 70-80°C, and setting the dynamic working pressure to greater than 13.8MPa , Spray the outer protective layer in 3 times, the first spraying thickness is 0.6-0.8mm, the second spraying coating thickness is 0.6-0.8mm, the third spraying coating thickness is controlled and the total thickness of the three sprayings is 2mm±0.2mm, Finally, the outer coating is subjected to external granulation or smooth surface treatment.

The beneficial effects of the utility model:

1. Improve the overall waterproof and aging resistance of the bulletproof sheet;

2. Improved production efficiency;

3. Solve the problem of unbalanced product quality due to manual operation;

4. Improve the bonding fastness between the outsourcing material and the fiber bulletproof sheet
