Problems solved by technology
[0003] In China, the patent authorization announcement number is CN103029386B, and the authorization announcement date is April 22, 2015. The invention title is "military puncture-resistant, tear-resistant, anti-static, high-barrier camouflage camouflage composite material" and introduces a solution to the current situation. Composite material with problems such as easy puncture, easy tearing, poor barrier property and poor flexibility of protective material and preparation method thereof
The composite material solves the problems as described well, but in actual use, there are still deficiencies: 1. The strength is not large enough to meet the various harsh environments of field operations; 2. When the external materials are aged or worn , there is still the phenomenon of being pierced; 3. When the composite material is used, especially when it is used as an envelope, if it is damaged, it can only be repaired from the inside of the envelope, which is very inconvenient

Embodiment Construction
[0033] combined with figure 1 And attached figure 2 As shown, a weather-resistant and high-barrier composite material for outdoor equipment storage includes an anti-aging high-strength layer 1, a high-barrier layer 2 and an antistatic heat-sealing layer 3. The composite material is prepared by the following method.
[0034] The preparation steps of composite materials include:
[0035] A. Preparation of anti-aging high-strength layer 1: Scrape and calender PVC slurry 12 on both sides of the mesh material with high-strength polyester 11 as the base cloth, and form anti-aging high-strength layer 1 by drying;
[0036] B, preparation of high barrier layer 2:
[0037] (1), carry out corona treatment to both sides of polyethylene terephthalate film (also claim polyester, PET);
[0038] (2) A polyamide film is bonded to the upper surface of the aluminum foil 22, and after compounding, the polyamide film layer 23 is formed on the upper surface of the aluminum foil 22 by aging at a...

Abstract
The invention relates to a weather-resistant and high-barrier composite material for outdoor equipment sealing and a preparation method thereof. The preparation method of the composite material comprises the following steps: firstly preparing an anti-aging high-strength layer, a high-barrier layer and an anti-static heat-sealing layer, respectively; The anti-static heat-sealing layer is compounded and then compounded with the anti-aging high-strength layer. The advantages of the present invention are: 1. The material has the characteristics of high barrier property, high strength, puncture resistance and combustion resistance, which is sufficient to meet various field operations. Harsh environment; 2. When the composite material is used, especially when it is used as an envelope, if it is damaged, it can be repaired from the outside of the envelope, and there is no need to remove the materials inside the envelope from the envelope, which is very convenient, safe and reliable.
Description
technical field [0001] The invention relates to a weather-resistant high-barrier composite material for outdoor equipment sealing and a preparation method thereof. Background technique [0002] During the storage and transportation of military materials, they are greatly affected by ambient temperature, humidity, light, and electromagnetism. Especially in harsh environments, the properties of military materials will change to varying degrees, and some may even deteriorate or become invalid. For this reason, the staff will generally take certain protective measures during the storage or transportation of military materials to ensure the safe storage and transportation of materials. [0003] In China, the patent authorization announcement number is CN103029386B, and the authorization announcement date is April 22, 2015. The invention title is "military puncture-resistant, tear-resistant, anti-static, high-barrier camouflage camouflage composite material" and introduces a solut...
