Embodiment 1

[0043] Example 1: Selection and optimization of the adhesive used in the aramid press plate.

[0044] Since the aramid fiber pressing cloth needs to be further pressed and formed, the adhesive required to be used first has the characteristics of hot pressing reaction. In addition, it should have a certain viscosity at room temperature (viscosity range is 80-200mPa.s), and the initial viscosity of the adhesive It directly affects the appearance of the aramid press cloth. According to literature research and small-scale simulation test, four kinds of adhesives were selected from more than ten kinds of adhesives for further comparison test of woven aramid press cloth. The comparison results are shown in Table 1.

[0045] Table 1 Influence of different adhesives on the appearance of aramid laminate

[0046]

[0047] From the analysis of the comparison results in Table 1, it can be seen that in the weaving process of acrylic and epoxy resin adhesives, due to the strong binding ...

Embodiment 2

[0048] Example 2: Selection and optimization of crosslinking agent in non-woven fabrics.

[0049] Due to trimethylolpropane-tris(3-aziridine) propionate, the three aziridine groups are very active and can be cross-linked with the hydroxyl groups in the acrylate adhesive at high density, and under high temperature and high pressure, nitrogen The propidyl group can also undergo a cross-linking reaction with the carbonyl group in the ester group, so that the formed non-woven fabric composite material has excellent heat resistance, weather resistance, light resistance, corrosion resistance, etc., and can also improve the formation of composite materials. bond strength and improve material flexibility. In this example, the addition of aziridine crosslinking agent is mainly to improve the interface between resin and fiber surface, and the interface is mainly composed of surface atoms and surface subatoms. The composition of matrix and fiber surface atoms depends on the affinity betw...

Embodiment 3

[0053] Embodiment 3: Optimization of the hot pressing process of aramid fiber pressing plate.

[0054] According to the performance parameters of the selected adhesive, the tentative hot-pressing temperature is 140°C (according to the empirical value, the hot-pressing temperature is preferably 20-50°C higher than the activation temperature of the adhesive), and the hot-pressing time is 15min (according to the fact that no gas is released during hot-pressing) phenomenon), the hot pressing pressure is 10MPa (depending on the pressure of similar products), and the performance results of the prepared aramid pressing plate material are shown in Table 3.

Abstract

The invention relates to the technical field of square cabins, and discloses a square cabin large plate and a square cabin. The shelter large plate comprises an inner skin, an outer skin and a bulletproof layer arranged between the inner skin and the outer skin. The bulletproof layer is composed of an aramid fiber pressing plate which is formed by pressing aramid fiber pressing plate cloth and non-woven cloth added with a cross-linking agent in a hot pressing mode on the basis of an adhesive. The square cabin comprises a plurality of square cabin large plates; the shelter large plates are connected and fixed through a plurality of first angular pieces, a plurality of second angular pieces and a plurality of corner pieces to form a shelter with a closed cavity inside. The bulletproof layer of the shelter large plate is composed of the aramid pressing plate formed by hot-pressing the aramid pressing plate cloth and the non-woven cloth added with the cross-linking agent on the basis of the adhesive, the shelter large plate adopts the aramid pressing plate with high bulletproof performance, and compared with a steel plate material, the weight of the bulletproof layer is reduced by 60% or above; the shelter prepared by using the shelter large plate can effectively reduce the energy consumption of a shelter vehicle and improve the maneuverability.

Description

technical field [0001] The invention relates to the technical field of shelters, in particular to a large slab of a shelter and a shelter. Background technique [0002] A square cabin refers to a box-type workshop that is organically combined with various sturdy materials, and its volume is fixed or expandable with protective properties and can be carried. Common shelters include: containers, container houses, special carriages, medical shelters, military shelters, meteorological shelters, mobile combined houses, etc. The shelter is similar to a container, and its standard is also formulated with reference to the container standard. Different equipment and devices are loaded according to different needs. Compared with containers, shelters have higher reliability, electromagnetic compatibility, air tightness, and thermal insulation. At present, the shelters used in military or armed areas pay more attention to the anti-ballistic performance and maneuverability of the shelte...
