Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1, the fingerprint-proof oil-proof highly-transparent protective film of the present embodiment includes a first modified PE layer, a first LR layer, a first HR layer, a first antistatic HC hardened layer, a modified PET layer, a second antistatic HC hardened layer, a second HR layer, a second LR layer, and a second modified PE layer, which are stacked in sequence.
The first modified PE layer and the second modified PE layer are the same in component, and the raw materials comprise the following components in parts by weight:
Figure BDA0002392812000000041
the softening agent is copolymerized propylene particles. The lubricant is one or more of zinc stearate, calcium stearate or potassium stearate.
By arranging the first modified PE layer and the second modified PE layer and modifying PE by using the formula, the antistatic property, the transparency, the toughness and the scratch resistance of the film layer can be obviously improved, so that the film layer also has good fingerprint and oil stain resistance on the premise of having good mechanical properties.
Wherein, tetrabromophthalic anhydride and polyacrylamide can form a network structure, and can improve the chemical crosslinking degree and the mechanical strength of PE, thereby enhancing the toughness and the scratch resistance. Triphenyl phosphite can effectively enhance the light stability of the product and maintain the transparency of the product.
Wherein, the compound addition of the indium oxide and the tin oxide can play a role in synergistic enhancement and improve the antistatic effect.
In one embodiment, the method for preparing the first modified PE layer and the second modified PE layer comprises the steps of: adding PE resin, tetrabromophthalic anhydride, polyacrylamide, triphenyl phosphite, indium oxide, tin oxide, a softening agent and a lubricant into a reaction container according to the parts by weight, heating to the temperature of 120-350 ℃, stirring for 2-5h, cooling and forming to obtain a first modified PE layer and a second modified PE layer.
The modified PET layer comprises the following raw materials in parts by weight:
Figure BDA0002392812000000051
the PET is modified by the formula, so that the light transmittance and the strength of the PET layer can be obviously improved.
The polybutylene terephthalate and the PET have a copolymerization reaction besides a blending effect, have a chain extension effect and can improve the molecular weight, so that the toughness and the comprehensive performance of the PET can be improved. The polyethylene wax has stronger internal lubrication effect, can enhance compatibility and transmittance.
The triphenyl phosphate and the phthalate are used as nucleating agents to promote crystallization, and can play a role of crystal nucleus in resin, so that the original homogeneous phase nucleation is changed into heterogeneous phase nucleation, the number of the crystal nucleus in a crystallization system is increased, the number of microcrystals is increased, the number of spherulites is reduced, the crystal size is thinned, the transparency of the resin is improved, and the haze is reduced.
The nano calcium carbonate can improve the crystallization rate of PET and promote crystallization, thereby improving the impact resistance, rigidity and toughness, and on the other hand, the nano calcium carbonate can improve the bonding property and improve the overall strength. The nano aluminum nitride can improve the strength and stability of PET. The surface atoms of the nano titanium dioxide particles have a plurality of dangling bonds and have unsaturated properties, so that the nano titanium dioxide particles are easy to combine with other atoms to tend to be stable and have high chemical activity. The crystallization rate can be further accelerated by adding the nano titanium dioxide, and the transparency is improved. Especially, when the nano titanium dioxide particles are mixed with nano calcium carbonate and nano aluminum nitride for use, a synergistic enhancement effect can be generated, the crystallization is promoted, the strength is improved, and meanwhile, the transparency and the toughness of the PET are greatly enhanced.
In one embodiment, the method for preparing the first modified PE layer and the second modified PE layer comprises the steps of: adding PET, polybutylene terephthalate, triphenyl phosphate, phthalate, nano titanium dioxide particles, nano calcium carbonate and nano aluminum nitride into a reaction container according to the parts by weight, heating to 110-300 ℃, stirring for 1.5-5h, cooling and forming to obtain the modified PET layer.

The HR layer is a high refractive index layer having a high refractive index, and in a preferred embodiment, the refractive index of each of the first HR layer and the second HR layer is 1.6-1.9. The LR layer, HR layer may be made of resin, which facilitates adjustment of refractive index by using resin, and the resin may preferably be curable resin such as thermosetting resin and photocurable resin; alternatively, the resin may be a thermoplastic resin such as an acrylic resin, an epoxy resin, a phenolic resin, or the like. In addition, it may be made of inorganic materials such as siloxane, titanoxane, and the like.
Further preferably, the first LR layer and the second LR layer each have a refractive index of 1.38, and the first HR layer and the second HR layer each have a refractive index of 1.65.
The first anti-static HC hardening layer and the second anti-static HC hardening layer are both anti-static HC hardening layers. The HC hardening layer can be made of polyethylene terephthalate, polymethyl methacrylate, cellulose triacetate, polycycloolefin or polyimide.

As can be seen from examples 1 to 3 and comparative example 7, the fingerprint and oil resistant high-transmittance protective film of the present invention has significant advantages in antistatic performance, light transmittance, haze, reflectance, etc. compared with the common transparent protective film on the market.
As can be seen from the comparison results of example 1 and comparative example 1, the first modified PE layer and the second modified PE layer of the present invention have more excellent antistatic, anti-fingerprint and anti-oil properties than the general PE film layer.
From the comparison results of example 1 and comparative example 2, it can be seen that the combination of tetrabromophthalic anhydride and polyacrylamide can improve the chemical crosslinking degree and mechanical strength of PE, thereby enhancing toughness and scratch resistance.
From the comparison results of example 1 and comparative example 3, it can be seen that indium oxide and tin oxide can achieve a synergistic enhancement effect and improve the antistatic effect.
As can be seen from the comparison results of example 1 and comparative example 4, the modified PET layer of the present invention has more excellent light transmission properties than general PET.
As can be seen from the comparison results of example 1 and comparative example 5, the transparency can be improved and the haze can be reduced by compounding triphenyl phosphate and phthalate.
From the comparison results of example 1 and comparative example 6, it can be seen that the transparency can be improved by using the nano titanium dioxide particles, nano calcium carbonate and nano aluminum nitride in combination.
While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
