The second PVC film 242 is adhesively bonded to the inner surface of the PI film facing away from the chemically resistant film 10. A second PI film 244 is positioned between the chemically resistant film 10 and the second PVC film 242.
In a third alternative example, referring to fig. 3, the anti-sparking film layer may further comprise an inner anti-sparking film layer. The inner anti-flash film layer includes a third PVC film layer 26. A third PVC film layer 26 is adhesively bonded to the inside surface of the chemically resistant film layer 10.
The first alternative example described above may be used in combination with the second alternative example and the third alternative example, respectively.
For example, as shown in fig. 2, the chemical protective clothing window 1 may include, from the outside to the inside, a first PVC film layer 222, a first PI film layer 224, a chemical permeation resistant film layer 10, a second PVC film layer 242, and a second PI film layer 244. Correspondingly, according to the specific structure of the chemical protective clothing window 1 to be manufactured, the first PVC film 222, the first PI film 224, the chemical permeation resistant film 10, the second PVC film 242 and the second PI film 244 with large sizes can be sequentially stacked to form a large-size stacked assembly to be punched.
As another example, as shown in fig. 3, the chemical protective clothing window 1 may include, from outside to inside, a first PVC film layer 222, a first PI film layer 224, a chemical permeation resistant film layer 10, and a third PVC film layer 26. Correspondingly, according to the specific structure of the chemical protective clothing window 1 to be manufactured, the first PVC film 222, the first PI film 224, the chemical permeation resistant film 10 and the third PVC film 26 with large dimensions can be sequentially stacked to form a stacked assembly with large dimensions to be punched.
It will be appreciated that the dimensions of the films in the figures are those after stamping. In fact, the anti-flash film and the chemically resistant film layer in this step are larger in size than in the figures. The drawings are cited herein only to illustrate the location of the various films.
Step four: and (3) carrying out stamping forming on the large-size laminated assembly to-be-bonded window 1.
In the step, according to the specific structural size of the chemical-resistant window 1 to be manufactured, all layers of films in the large-size chemical-resistant film and the anti-flaming film are formed into the window 1 to be bonded with a small-size structure through stamping. Thus, the whole outline of the chemical protective clothing window 1 is formed, wherein the size and the position of each film layer are determined.
Step five: EVA hot melt adhesive treatment is carried out on the section of the window 1 formed by punching, and the chemical protective clothing window 1 in the first embodiment is formed.
Under this step, EVA hot melt adhesive treatment is performed on the cross section of the punched window 1, so that adjacent films in each layer of film of the chemical protective clothing window 1 can be bonded through EVA hot melt adhesive in a hot pressing manner, and thus the chemical protective clothing window 1 in the first embodiment is formed.
The EEVA hot melt adhesive is prepared by taking ethylene-vinyl acetate copolymer as a main raw material. The EEVA hot melt adhesive is solid at normal temperature, is heated and melted into a flowable liquid adhesive with certain viscosity, and can be solidified again after cooling to form the bonding between materials. For example, EEVA hot melt adhesive may be compounded using a hot press such as a press or a roll compounding machine.
According to the invention, the anti-flaming film layer is arranged, so that the anti-flaming window resists flaming impact, and can play a role in blocking flaming. The anti-flaming film layer is adhered to the inner side surface, the outer side surface or the outer side surface of the chemical permeation resistant film layer, so that the anti-flaming performance of the whole anti-flaming garment window is good, and flaming can be effectively blocked.
The anti-flashover film layer material may comprise one or a combination of more of a PVC film, PI film. The PI film is a high flame-retardant carbonized film which is resistant to high temperature and fire, and the PI film can form a carbonized layer in flame so as to play a role in blocking the flashover, so that the whole product has good flashover resistance and can effectively block the flashover.
The PVC film has good fire resistance and flame retardance, so that the chemical-resistant window has good flame retardance. The inner and outer surface layers of the antichemical clothes window are all arranged to be PVC films, and the antichemical clothes window is easy to carry out gluing processing with the large fabric of the antichemical clothes. PVC color is easy to process, so that the inner and outer surface layers of the chemical protective clothing window are easy to produce into the required color.
The chemically resistant film layer may include a variety of combinations of PTFE films, FEP films, PEA films, PPS films. The chemical permeation resistant membrane layer integrates the advantages and characteristics of each membrane, and has good chemical permeation resistance and excellent chemical permeation resistance. The chemical protection window of the anti-flashover chemical protection clothes has various types and long time.
The PVC film, the PI film and the chemical permeation resistant film layer in the anti-flaming chemical suit window have excellent transparent effects, and the sight of a chemical suit wearer is not influenced.
