Embodiment 1

[0031] The anti-virus and flame-retardant flexible transparent composite material of this embodiment includes an inner protective layer 1, a resin film 3, a barrier layer 2, a resin film 5, and an outer protective layer 4 from the inside to the outside. For substances that can last for more than 72 hours, the protective layer is transparent, airtight and foldable. The transparent composite material has a protective time against mustard gas of more than 72 hours, a flame retardancy of UL94-V-0, and a light transmittance of 91.5%. The composite transparent material has good cold resistance. It can be folded in half at 180° at -40°C without cracking. It is light, soft and foldable.

[0032] The inner protective layer 1 and the outer protective layer 4 of the present embodiment are all flame-retardant polyether thermoplastic polyurethane (TPU) elastomers, and the thicknesses are respectively 0.15mm and 0.2mm. The film has strong cold resistance, high transparency and smooth surfac...

Embodiment 2

[0041] The composition of the composite material of this embodiment is the same as that of Embodiment 1, except that the inner and outer protective layers of this embodiment are polyvinyl chloride (PVC) films with thicknesses of 0.2 mm and 0.3 mm, respectively. The polyvinyl chloride material has high transparency, excellent chemical stability, and excellent anti-corrosion performance; the barrier layer is still a polyester (PET) film with a thickness of 0.025mm; the thickness of each layer of material is 0.15mm. Polyurethane (PU) optical film vacuum hot pressing compound.

[0042] The preparation method of the composite material in this example is the same as that in Example 1. The flame-retardant polyvinyl chloride film is prepared by tape casting, and the polyurethane optical film is used for vacuum hot-compression lamination. The lamination temperature is 90° C. and the pressure is 10 MPa.

[0043] The following is a list of polyvinyl chloride film requirements that are fe...

Embodiment 3

[0048] The inner and outer protective layers of the composite material in this embodiment are both flame-retardant polyethylene films, with thicknesses of 0.1 mm and 0.25 mm, respectively. The barrier layer is biaxially stretched nylon film with a thickness of 0.015mm. The polyethylene film material has light specific gravity, less dust absorption and high light transmittance.

[0049] The preparation method of the composite material in this example is composite processing of blow molding and hot pressing. The transparent flame-retardant polyethylene film was prepared by blow molding process, and then the 0.2mm flame-retardant ethylene-vinyl acetate copolymer optical film was used for vacuum hot-compression lamination. The lamination temperature was 95°C and the pressure was 9MPa.

[0050] The following is a list of possible polyethylene film properties in this embodiment.

Abstract

The invention is an anti-virus flexible transparent composite material and its products. The material includes an inner protective layer, a barrier layer and an outer protective layer from the inside to the outside. At least one of polyamide (PA), polyester (PET) or ethylene-vinyl alcohol copolymer (EVOH) that can be folded and mustard gas protection time can reach more than 72 hours; the inner and outer protective layers are transparent , Polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) copolymer, ethylene-vinyl alcohol copolymer (EVOH), ethylene-vinyl acetate copolymer ( At least one of EVA) and thermoplastic polyurethane elastomer (TPU); the composite material has a protection time of mustard gas of more than 72 hours, a light transmittance of more than 90% in the visible light range, and can be pressed and folded at 180°.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to an anti-virus flexible transparent composite material and its products. Background technique [0002] The window is the medium for the staff to detect the internal and external working environment of the product. Usually, window materials of different materials are configured according to different usage requirements and environments. Traditional windows are mostly made of hard materials, which are used for shelter windows, pipeline mirrors, display screens, and face screens. Such windows cannot be folded, and are more used for hard equipment, and do not have nuclear, biological and chemical protection performance. [0003] At present, common window materials are mainly based on float glass, polycarbonate and polyethylene terephthalate materials, and modified resins. Polycarbonate, polyethylene terephthalate, and modified resin materials are relatively Because the float glass ma...
