Description
Technical Field
The invention relates to the field of mobile phone glass rear cover coatings, in particular to a mobile phone glass rear cover coating liquid and a preparation method and application thereof.
Background
The development of science and technology promotes the improvement of the living standard of human beings, the development of internet technology enables electronic products to become an indispensable part in the life of people, people pay attention to the protection of a screen display screen of a mobile phone and the rear cover of the glass of the mobile phone, and the smoothness of the rear cover of the glass of the mobile phone becomes a hot spot of public attention. At present, related researches mainly focus on fingerprint resistance, hydrophobicity, anti-glare and other functions of the rear cover of the glass of the mobile phone.
However, the dynamic friction coefficient of the surface of the existing coating modified by the anti-fingerprint oil is 0.01-0.02, the surface smoothness is too high, and the coating is easy to slip when being used as a coating of a rear cover of mobile phone glass. The water resistance and oil resistance of the existing hydrophobic and oleophobic coating can repel the grease components attached to the rear cover coating of the mobile phone glass, and the dirt is more obvious visually. In addition, the anti-fingerprint oil coating has weak adhesive force and poor durability, and cannot meet the requirement of long-time anti-fingerprint. By using AG (Anti-Glareglass) mist etching process, the surface of the rear cover of the mobile phone glass has frosted texture to achieve the effects of Anti-glare and Anti-fingerprint, but the glass surface has a nano-convex array structure, so that the surface smoothness is poor, and the touch hand feeling is influenced. Therefore, a coating with moderate smoothness, fingerprint resistance and easy cleaning is needed to replace the existing coating so as to solve the problems of rough surface, poor smoothness and unobvious fingerprint prevention effect of the existing mobile phone glass rear cover coating.
Disclosure of Invention
Based on the above, the invention aims to provide the mobile phone glass rear cover coating liquid which has the advantages of moderate smoothness, wear resistance and excellent fingerprint prevention effect.
A coating liquid for a rear cover of mobile phone glass comprises the following components in parts by weight:
0.625-1.0 part of organic siloxane;
6.25-10.0 parts of solution A;
90-100 parts of a solvent;
wherein the solution A is a solution obtained by diluting the modified POSS with the solvent to a mass concentration of 1%.
Polyhedral oligomeric silsesquioxanes (POSS) are organic/inorganic hybrid molecules with a cage-shaped core-shell structure, the core of which is similar to SiO 2 In the form of a cageNanoparticles, used in coating substances, can increase the surface hydrophobicity of materials. Therefore, the super-hydrophobicity and the nano-scale of POSS provide a possible way for realizing the hydrophobic function of the surface of the material. However, the super-hydrophobicity of POSS directly applied on the surface of the material can affect the smoothness of the surface of the material. The invention relates to a coating liquid for a rear cover of mobile phone glass, which comprises the following components in parts by weight: 0.625-1.0 part of organic siloxane; 6.25-10.0 parts of solution A; 90-100 parts of a solvent; wherein the solution A is a solution obtained by diluting the modified POSS with the solvent to a mass concentration of 1%. Firstly, the modified POSS introduces hydrophilic groups on the basis of the POSS; compared with the super-hydrophobicity of the POSS, the modified POSS has certain hydrophilicity due to the introduction of hydrophilic groups, so that the water contact angle can be reduced; meanwhile, by regulating and controlling the proportion of the organic siloxane to the solution A, namely regulating and controlling the proportion of the organic siloxane to the modified POSS, the surface of the coating prepared by the coating liquid for the rear cover of the mobile phone glass disclosed by the invention obtains moderate smoothness and excellent moderate hydrophobic cleaning capability, and the wear resistance of the surface of the coating is also improved. Secondly, on one hand, the oleophylic groups on the organosiloxane and the modified POSS are utilized to enable oil and fat substances in fingerprints to be easily dissolved or dispersed, and the oil and fat can be quickly spread and spread on the surface of a coating prepared by the mobile phone glass rear cover coating liquid, so that originally uneven fingerprints are flattened, the sensitivity of vision to the fingerprints on the surface of the coating is reduced, and the effect of hiding the fingerprints is achieved visually; on the other hand, the modified POSS has a nano structure which not only enlarges hydrophobic and lipophilic properties, but also can reduce the contact area of fingerprints on the surface of a coating prepared from the coating liquid, reduce the surface adhesion and reduce the deposition amount of the fingerprints, so that the fingerprint grease is easy to remove; under the combined action of the oleophylic group and the nano structure, the coating surface prepared by the coating liquid has an excellent fingerprint-proof effect. In addition, Si-O on the organosiloxane and the modified POSS can be cut off to react with-OH on the surface of the glass substrate, so that the mobile phone glass rear cover coating liquid provided by the invention is applied to glassThe adhesion on the substrate surface is enhanced.
Further, the weight portion of the organic siloxane is 0.625-0.7 portion; the weight portion of the solution A is 6.25-8.0 portions.

Further, the modified POSS is alcohol containing a mercapto substituent group, and/or POSS which is synthesized by addition reaction of siloxane and OVPOSS and has hydroxyl or siloxane containing sulfur elements. Octavinyl oligomeric silsesquioxane (OVPOSS) is used as a core molecule, and alcohol containing a mercapto substituent and siloxane containing a mercapto substituent are connected to a cage structure of the OVPOSS by using an addition reaction, namely S-H breakage and vinyl addition on the OVPOSS are carried out to synthesize POSS with hydroxyl or siloxane groups. Compared with the OVPOSS before modification, the modified POSS containing the sulfur element and having hydroxyl or siloxane groups contains a plurality of hydroxyl or hydrophilic groups such as methoxyl, ethoxyl, propoxyl and the like on the original siloxane containing the mercapto substituent, so that the POSS has certain hydrophilicity, the water contact angle can be reduced, and the smoothness of the coating surface prepared by the coating liquid is moderate after regulation and control.
Further, the modified POSS is polymerized POSS synthesized by polymerization reaction of acrylate containing olefin and OVPOSS. The acrylate containing olefin is polymerized with the OVPOSS through polymerization reaction, namely, vinyl double bonds on the OVPOSS and double bonds on the acrylate are polymerized, so that a plurality of polymers are connected with the obtained polymerized POSS, the polymerized POSS has certain hydrophilicity, the water contact angle can be reduced, and the coating prepared by the coating liquid for the rear cover of the mobile phone glass has moderate smoothness after regulation and control.
Further, the organic siloxane has a general formula of R A -Si(R B ) 3 (ii) a The R is A Is (C) 10 -C 18 ) Straight chain alkyl radical, COO (C) 10 -C 18 )、(C 10 -C 18 ) One of an alkenyl group; the R is B Is O (C) 1 -C 3 ) One kind of alkyl group. In this range of organosiliconsThe alkyl has better hydrophobic and oleophylic effects, and the coating liquid mixed with the solution A and the solvent ensures that the coating prepared by the alkyl has better effect of hiding fingerprints in visual effect.
Further, the solvent is one or more of ethyl acetate, methanol, ethanol, isopropanol and cyclohexane. The boiling points of ethyl acetate, methanol, ethanol, isopropanol and cyclohexane are relatively low, one or more solvents are adopted as the solvents, and when the coating liquid is applied to other base materials, the solvents are easy to volatilize in the baking process, and the oleophylic and hydrophobic effects of the organosiloxane and the modified POSS are not influenced.

Surface treatment coatings C formed on glass for examples 1 to 8 and comparative examples 1 to 6 1 -C 14 The hydrophobic and oleophobic property, the slip property and the wear resistance of the rubber are tested.
1. Measurement of hydrophobicity
Surface treatment coatings C formed on glass for examples 1 to 8 and comparative examples 1 to 6 1 -C 14 The surface treatment coating C was measured using a contact angle measuring instrument (XHS-CAZ1, Shenzhen Xinshensen instruments Ltd.) 1 -C 14 The contact angle for water and the contact angle for n-hexadecane. The measurement uncertainty was ± 1.3 °. The test results are shown in Table 1.
2. Measurement of slip Property

loading: 1 kg; moving stroke: 40 mm; moving speed: 60 rpm. The test results are shown in Table 2.
TABLE 1
TABLE 2
Compared with comparative examples 1 and 2, the surface treatment coatings formed in examples 1 to 8 are not wear-resistant because the surface treatment coatings of comparative examples 1 and 2 are monomolecular layers and have weak bonding force with the glass substrate, so that nano structures are formed on the surface of the surface treatment coating by adding the modified OVPOSS, namely the modified POSS, and the wear resistance of the surface treatment coating is remarkably improved. Meanwhile, the modified OVPOSS, namely the tail end of the modified POSS has hydrophilicity and lipophilicity, so that the water contact angle and the hexadecane contact angle are greatly reduced. Further, it is understood from comparative example 1 that the organosiloxane amount is less than 0.625g, and the surface treatment coating is not abrasion resistant.
Compared with comparative example 6, the modified OVPOSS, namely the modified POSS, formed by the surface treatment coatings in examples 1-8 is attached to the glass surface independently, and the hydrophobic and oleophilic performances of the modified OVPOSS are poor. As can be seen from examples 5 to 6, if the amount of the organosiloxane is 1g or the amount of the solution A is 10g, the water contact angle of the surface-treated coating is more than 90 ℃ or less than 65 ℃, and if the amount of the organosiloxane exceeds 1g or the amount of the solution A exceeds 10g, it is not favorable to ensure that the hydrophobicity of the surface-treated coating is moderate. Therefore, by combining the nano structure of the modified POSS and the hydrophobicity and lipophilicity of the organic siloxane, the proportion of the modified POSS and the organic siloxane can be properly selected to regulate and control the water contact angle of the surface treatment coating to be 80 +/-15 degrees and the hexadecane contact angle to be less than 40 degrees, so that the coating is more moderate in smoothness and easy to clean.
In the coating liquid for the rear cover of the glass mobile phone, the organic siloxane is preferably 0.625-0.7 part by weight; the weight part of the solution A is preferably 6.25 to 8.0 parts. From examples 1 to 8, it can be seen that the surface treatment coating has a moderate degree of slip, a good hydrophobic and oleophilic effect, and a significant fingerprint-resistant effect, when the dosage of the organosiloxane is 0.625 to 0.7g and the dosage of the solution A is 6.25 to 8.0 g.
In the coating liquid for the rear cover of the glass mobile phone, a proper amount of additives can be added according to actual requirements, so that the performance of the coating liquid is improved.
Compared with the prior art, the coating liquid for the rear cover of the glass mobile phone, disclosed by the invention, is characterized in that firstly, hydrophilic groups are introduced into the modified POSS on the basis of the POSS; compared with the super-hydrophobicity of the POSS, the modified POSS has certain hydrophilicity due to the introduction of hydrophilic groups, so that the water contact angle can be reduced; meanwhile, the proportion of the organic siloxane to the solution A, namely the proportion of the organic siloxane to the modified POSS is regulated, so that the surface of the coating prepared by the coating liquid for the rear cover of the mobile phone glass has moderate smoothness and excellent moderate hydrophobic cleaning capability, and the wear resistance of the surface of the coating is improved. Secondly, on one hand, the oleophylic groups on the organosiloxane and the modified POSS are utilized to enable oil and fat substances in fingerprints to be easily dissolved or dispersed, and the oil and fat can be quickly spread and spread on the surface of a coating prepared by the mobile phone glass rear cover coating liquid, so that originally uneven fingerprints are flattened, the sensitivity of vision to the fingerprints on the surface of the coating is reduced, and the effect of hiding the fingerprints is achieved visually; on the other hand, the modified POSS has a nano structure which not only enlarges hydrophobic and lipophilic properties, but also can reduce the contact area of fingerprints on the surface of a coating prepared from the coating liquid, reduce the surface adhesion and reduce the deposition amount of the fingerprints, so that the fingerprint grease is easy to remove; under the combined action of the oleophylic group and the nano structure, the coating surface prepared by the coating liquid has an excellent fingerprint-proof effect. In addition, Si-O on the organosiloxane and the modified POSS can be cut off to react with-OH on the surface of the glass substrate, so that the adhesion of the coating liquid of the mobile phone glass rear cover on the surface of the glass substrate is enhanced. The preparation method of the coating liquid for the rear cover of the glass mobile phone is simple and easy to obtain. The coating liquid for the rear cover of the glass mobile phone is suitable for forming a surface treatment coating on the surface of various base materials, particularly optical components requiring permeability.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, to those skilled in the art, changes and modifications may be made without departing from the spirit of the present invention, and it is intended that the present invention encompass such changes and modifications.
