Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: an embodiment of an goggles sheet material for a protective mask comprises a PET core material layer 101, wherein a first PETG substrate layer 102 is arranged on the upper surface of the PET core material layer 101, a second PETG substrate layer 103 is arranged on the lower surface of the PET core material layer 101, a first hydrophobic nano-adhesive film 104 is adhered on the surface of the first PETG substrate layer 102 through a first adhesive layer, a second hydrophobic nano-adhesive film 105 is adhered on the surface of the second PETG substrate layer 103 through a second adhesive layer (the first adhesive layer and the second adhesive layer are not shown in the figure due to thinness), wherein the structure that the upper surface and the lower surface of the PET core material layer 101 wrap the first PETG substrate layer 102 and the second PETG substrate layer 103 is manufactured by utilizing a three-layer composite sheet material machine, wherein the PETG sheet material has outstanding toughness and high impact strength, meanwhile, the transparency is higher, the PETG processing and forming performance is excellent, and any shape design can be carried out according to the intention of a designer, in this embodiment, because the goggles are generally non-planar structures with a certain radian, PETG is used for processing, and the goggles have better molding capability, and the PET core layer is disposed on the inner side of the goggles for cost reduction.

First hydrophobic nanometer pad pasting and the hydrophobic nanometer pad pasting of second include the PET substrate layer and the cladding at the hydrophobic nanometer coating on PET substrate surface, and the PET substrate layer mainly plays the function of attaching to the nanometer coating, through the hydrophobic nanometer coating structure on inboard and outside surface, makes this goggles sheet, can prevent the raindrop outward, prevents the fog in.

The hydrophobic nano coating is a fluorocarbon polymer processed on the surface of the PET substrate layer in a PECVD (plasma enhanced chemical vapor deposition) mode, the processing environment is normal temperature, the power is low, pollution cannot be caused, and the used material is extremely saved due to the extremely thin nano coating.

The thickness of the hydrophobic nano coating is 20nm-50 nm.

Still including covering the first type membrane of leaving type on first hydrophobic nanometer pad pasting surface and covering the second on second hydrophobic nanometer pad pasting surface from the type membrane, these two kinds of types of membrane can use ordinary PVC film from type, mainly carry out the effect of protection in the intermediate process, need tear before weaving the matte material with the main part and assemble.

The first gluing layer and the second gluing layer are thermosetting acrylic resin glue layers, the hydrophobic nano film can be tightly attached to the surface of the PETG by using the glue, and no glue trace is left.

The processing principle is as follows: firstly, processing a three-layer composite sheet by using a sheet machine, wherein the three-layer composite sheet comprises a PET (polyethylene terephthalate) core material positioned in the center and PETG sheets coated on two outer surfaces of the PET core material, then coating acrylic resin glue on the surfaces of the PETG sheets on two sides by using a coating machine, then respectively laminating a first hydrophobic nano film and a second hydrophobic nano film on the glue on the surfaces of the PETG sheets on two sides by using a laminating machine, and finally, baking and curing the glue to obtain the belt product.

The processing principle of the first hydrophobic nano adhesive film and the second hydrophobic nano adhesive film is as follows: placing transparent PET substrate into plasma coating machine and carrying out PECVD coating, make the hydrophobic nanometer pad pasting of taking the nanometer coating at last, the nanometer coating is fluorocarbon polymer, the thickness of nanometer coating is preferably 20-50nm, because the hydrophobic characteristic of nanometer coating, the aqueous vapor molecule of breathing touches colder sheet and condenses into the dribble, be difficult to adhere to on the nanometer coating, can automatic landing, so the goggles sheet has kept cleaner dry internal surface, the growth of bacterium has been suppressed, the water droplet in the outside falls on the goggles surface simultaneously, also be difficult to adhere to, can not influence the sight, consequently, have outer rain-proof, the effect of interior anti-fogging.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
