Description

Antistatic inorganic nano-coating composition, transparent coating and antistatic product

Technical Field

The invention relates to an antistatic inorganic nano-coating composition, a transparent coating and an antistatic product, belonging to the field of nano-materials.

Background

Inorganic nanomaterials such as tin oxide and indium tin oxide have high conductivity, while inorganic nanomaterials such as tungsten oxide and cerium oxide have high hardness, which is common knowledge in the field of materials. When the nano material is dispersed in the liquid, if the nano coating obtained by only using stirring or grinding equipment is easy to settle and separate, the adhesion of the coating is poor even if the nano coating is coated into a film. Therefore, people can only add auxiliary agents such as a dispersing agent and a film forming agent and compound substances such as resin and an adhesive to uniformly disperse the nano materials and prepare the nano coating with qualified adhesive force, but the auxiliary agents and the compound substances are usually cured in the prepared coating together with the nano materials, which undoubtedly reduces the original performance of the nano materials in the coating of the product, for example, the auxiliary agents such as an organic dispersing agent and a film forming agent reduce the conductivity among nano indium tin oxide particles in the coating, and the compound substances such as resin and an adhesive reduce the hardness of the nano cerium oxide coating.

Static electricity can be used in spraying and copying equipment, but is often destroyed in human production and life, such as short circuit of electrical appliances, fire in workshop, and large amount of dust on object surface.

According to the definition of the existing national standard GB/T1410-2006 solid insulating material volume resistivity and surface resistivity test method: the surface resistance is the quotient of the voltage applied between the two electrodes on the surface of the sample and the current flowing between the two electrodes in a predetermined electrochemical time, and the possible polarization formed at the two electrodes is negligible. The sheet resistivity (ρ s) is the quotient of the direct current field strength and the line current density in the surface layer of the material, i.e. the sheet resistance per unit area, the size of which is unimportant. The SI unit of surface resistivity is in ohms (Ω), and is actually commonly expressed as "ohm-square units" with the notation Ω/□ or Ω/sq.

The smaller the surface resistance or surface resistivity of the material is, the less likely static electricity is generated.

Surface resistivity ρ s > 10¹²The material of (Ω/□) is an insulator, and is liable to generate static electricity and unable to discharge itself, and thus does not have an antistatic function.

Surface resistivity of 10⁵(Ω/□)＜ρs≤10¹²The material (Ω/□) is called a static dissipative material because it has a function of discharging static electricity.

Static conductive and static dissipative materials are collectively referred to as antistatic materials.

People try to prepare an antistatic coating on the surface of an insulator through an antistatic coating so as to reduce the harm of static electricity generated on the surface of the insulator.

Currently, the antistatic coating disclosed in the patent literature is usually prepared by adding conductive fillers (such as conductive mica powder, conductive zinc oxide, conductive potassium titanate whisker, conductive auxiliaries, etc.) into high molecular organic resins or organic emulsions such as epoxy resin, polyurethane resin, acrylic resin, etc., and the application numbers of such patents are 03816920.7, 201510743569.1, 201610603379.4, 201410791784.4, 201510858308.4, 201310456714.9, 201410414741.4, 201610590841.1, 201310058652.6, 201610603620.3, 201610238732.3, 2014104310062.5, 201510455248.1, 201310338916.3, 201510458075.9, 201510806724.X, 201610371777.8, 2016103308100.7, 201510859184.1, 200810041949.0, 201510786491.1, 201410831053.8, 2014105199.3, 20141038807.9, 201310516318.0, 201510069301.4, 201510460435.9, 201410680438.9, 201510516728.4, 201310728978.5, 201310366329.5, 201410735864.8, 2016107256465, 201410624512.5, 201110307596.6, 201510609403.0, 201410823568.3, 2016102877100.0, 201310587846.5, 201510361227.3, 201610256618.3, 201510877227.9, 201210590489.3, 201610204271.8, 201510678789.0, 201310338916.3, 201310654484.7, 201410741592.2, 200510025368.4, etc. These antistatic coatings contain organic substances such as resins, which not only reduce the antistatic effect of the coating and the product, but also reduce the outdoor service life thereof.

At present, the electrostatic dissipative coating materials disclosed in the patent documents are also added with organic substances such as resins, for example, the electrostatic dissipative coating layer with patent application number 201480021995.8 contains organic substances such as "fluorine-containing polymer, silicone or hydrocarbon polymer"; the coating of patent application No. 201180034645.1 contains 5-15wt% of a polymeric binder; the patent with application number 200480032649.6 is to add conductive polymer into organic sol such as polyvinyl chloride and polymethyl methacrylate; the coating layer of patent application No. 200780034249.2 contains organic binders such as polyolefin and polyester; the 200880122764.0 patent discloses a static dissipative multilayer sheet processed by twin screw thermoplastic extrusion, not in the coating category; the 201280024640.5 patent discloses static dissipative polycarbonate compositions that are thermoplastic extruded and are also not in the coating category; the patent application No. 201510606526.9 discloses an alumina antistatic ceramic material and a preparation method thereof, wherein the antistatic material is also a pure inorganic substance, but is an alumina ceramic body which is sintered at a high temperature of 1100-1600 ℃, and does not belong to the field of coating. The 201510078567.5 patent discloses the use of polycondensation to incorporate organic antistatic agents into PET polymer materials, and is not in the coating category.

Currently, the transparent conductive film layer coating materials disclosed in patent documents each contain an organic component such as a resin, and for example, the coating material disclosed in patent application No. 201010003998.2 "a transparent conductive film containing conductive inorganic particles and a resin component" and the coating material disclosed in patent application No. CN03101618.9 "a binder such as an organic resin" and an auxiliary agent such as a "surfactant" are contained.

In order to obtain an antistatic coating with uniform dispersion and a coating with qualified adhesive force, organic substances such as a dispersing auxiliary agent, resin, a binder and the like are forced to be added into the coating disclosed by the patent documents and remain in the coating, so that the conductivity between conductive materials in the coating is reduced, and the defects of poor antistatic effect, low hardness, no high temperature resistance, short outdoor service life and the like of the coating are difficult to overcome.

Although some inorganic antistatic coatings are disclosed in patent and literature, the antistatic coatings prepared by the inorganic antistatic coatings are opaque and cannot be used on objects requiring transparent coatings, such as electronic display screens, glass, glasses, photovoltaic panels and the like. For example, although patent application No. 201410104925.0 discloses "a dustproof antistatic inorganic composite coating", it uses common inorganic substances rather than nano materials, so the coating is not transparent. As is well known, a nano material is a material which has at least one dimension in a three-dimensional space in a nano size (0.1 to 100nm) or is composed of the nano size and the nano size as a basic unit, and is obviously different from a common inorganic substance without size characteristics. Although the patent with the application number of 201410447099.X discloses a preparation method of a transparent antistatic inorganic film layer, the preparation method belongs to a physical magnetron sputtering method and is not formed by coating a coating.

Disclosure of Invention

Problems to be solved by the invention

The current antistatic coating contains organic matters such as dispersant, resin, adhesive and the like, so that the antistatic effect of the coating and a product can be reduced, the outdoor service life of the coating and the product can also be reduced, and the antistatic coating of an electronic display screen, glass, glasses, a photovoltaic panel and the like is required to have transparency, bendability, outdoor weather resistance and the like, so that the inorganic nano coating is expected to be used for preparing the antistatic coating. However, many inorganic nano materials are synthesized by high-temperature calcination and other processes, so that mutually repulsive functional groups (such as hydroxyl groups) are lacked on the surfaces of the nano materials, additives such as a dispersing agent and the like are required to be added to uniformly disperse the inorganic nano materials into liquid such as water and the like, and complex substances such as an organic adhesive, a high-molecular resin and the like are required to be added to obtain a coating with qualified coating adhesion when the coating is coated and formed, but the organic additives and the complex substances are usually cured in the prepared coating together with the nano materials, so that the original performances of the nano materials in the coating of the product, such as the conductivity and antistatic performance of the nano materials such as nano indium tin oxide and the like, are reduced. Although the high-temperature calcination can also remove organic matters in the coating, the resulting pores deteriorate the adhesion and weather resistance of the coating, and many substrates are not resistant to high temperature.

Means for solving the problems

The principle of the invention is as follows: during or after the synthesis of the conductive and hard inorganic nano materials, modifying the conductive and hard inorganic nano materials by using a modifier containing peroxy (-O-O-), so that the surfaces of the nano materials are modified with negative charges of the same hydroxyl group to repel each other and inhibit the particle agglomeration of the nano materials. The nano coating can keep even dispersion and no sedimentation or layering for a long time without adding a dispersing agent, and when the coating is formed into a film and a solvent is volatilized and completely cured, negative charges on hydroxyl groups are released through the coating, so that the coating can obtain strong adhesive force no matter the nano material and the surface of a product are attracted by the hydroxyl groups to form intermolecular force during low-temperature curing or covalent bonds formed by dehydration and condensation of the hydroxyl groups during high-temperature curing, and the inorganic nano coating does not need to be added with substances such as dispersing agents, resins, adhesives and the like, and the prepared coating is composed of pure conductive and hard inorganic nano materials so as to improve the antistatic property, the transparency, the weather resistance and the outdoor service life of the coating of the product.

The hard inorganic nano material includes, but is not limited to: silicon oxide (SiO)₂) Tungsten oxide (WO)₃) Titanium oxide (TiO)₂) Cerium oxide (CeO)₂) Alumina (Al)₂O₃) One or more of (a). Such hard inorganic nanomaterials are represented by the letter B.

3. Modifying the surface of the A and B nano materials by using a modifier to modify hydroxyl, wherein the modifier is characterized by containing a peroxy-O-O-compound. Modifiers include, but are not limited to: hydrogen peroxide (H)₂O₂) Sodium peroxide (Na)₂O₂) Potassium peroxide (K)₂O₂) Peroxy, peroxyCalcium (CaO) conversion₂) Magnesium peroxide (MgO)₂) Zinc peroxide (ZnO)₂) Potassium hydrogen peroxymonosulfate (KHSO)₅) Strontium peroxide (SrO)₂) Barium peroxide (BaO)₂) Potassium persulfate (K)₂S₂O₈) One or more of (a). The modifier can be added into a reaction system to perform peroxy modified surface modification on hydroxyl on the synthesized nano material, or the modifier and the synthesized or purchased dispersion liquid of the inorganic nano material can be put into a reactor to perform peroxy modified surface modification on hydroxyl. The inorganic nanomaterials A and B with peroxy-modified surface-modified hydroxyl groups can be obtained by using conventional equipment such as a reactor, e.g., a high-pressure reactor, an atmospheric pressure reactor, a hydrothermal reactor, an organic thermal reactor, a microwave reactor, a stirrer, a nano-mill, a ball mill, a sand mill, a homogenizer, and the like, and equipment associated with the reactor, e.g., a heater, a cooler, a pressurizer, a stirrer, a microwave generator, and the like, and then washing off impurities such as modifier residues and the like. The principle schematic diagram of the peroxy group modified surface modified hydroxyl group is shown in fig. 1 and fig. 2.

4. The inorganic nano material treated by the surface modifier is directly dispersed in a hydrophilic solvent by using stirring or grinding equipment to prepare the antistatic nano coating, and the antistatic nano coating comprises the following components:

0.001-60 parts by weight of a peroxy-modified surface-modified hydroxyl group-containing conductive inorganic nano material;

0.001-20 parts by weight of a peroxide-modified surface-modified hydroxyl-based hard inorganic nano material;

20-99.998 parts of hydrophilic solvent.

The hydrophilic solvent is preferably water, and water and a hydrophilic organic solvent may be used in combination.

For objects with surface lacking hydroxyl groups, a silica underlayer is prepared in advance, and the preparation method is such as magnetron sputtering method, silica sol method, silica coating method, etc., and these specific methods have many publications and are well known and used by related enterprises, and are methods which can be implemented by persons skilled in the art without any creative work.

6. The antistatic inorganic nano-coating is coated on the surface of an object by using tools such as spraying, curtain coating, roller coating, spin coating and the like, and is cured at low temperature of-50-4000 ℃, room temperature and high temperature. The water and the organic solvent are only present in the antistatic nano-coating and not present in the coating and the product, so that the characteristic that the antistatic coating is composed of inorganic nano-materials is not influenced.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the invention, after the inorganic nano material is subjected to modification treatment and hydroxyl group modification by the modifier containing peroxy-O-O-, the hydroxyl group content on the surface of the nano material is remarkably increased (the hydroxyl group enhancement signal can be detected by infrared spectroscopy), particle agglomeration is inhibited because the nano material surface has the same negative charge of hydroxyl group and repels each other, and the nano material can be prepared into a uniformly dispersed coating without sedimentation for a long time even if no dispersant is added.

When the nano coating is coated on the surface of an object, hydrophilic solvents such as water, methanol, ethanol, isopropanol and the like are completely and naturally volatilized at low temperature and room temperature to prepare a product with the antistatic inorganic nano transparent coating, negative charges carried by hydroxyl groups on the surfaces of the conductive nano material A and the rigid nano material B are released through the coating, and intermolecular attraction (also called van der Waals force, the principle is shown in figure 3) is formed by the mutual attraction of hydrogen atoms and oxygen atoms between the hydroxyl groups on the surfaces of the nano particles and the object, and the attractive force can enable the coating cured at the low temperature and the room temperature to obtain qualified adhesive force and wear resistance.

When the coating is heated and cured at the temperature of 100-4000 ℃, the hydroxyl on the surface of the nano material A, the hydroxyl on the surface of the nano material B and the hydroxyl on the surface of an object can be changed into an-O-covalent bond after losing one water molecule due to the heating of the two hydroxyls (the principle is shown in figure 4), and the coating has very strong adhesive force, hardness and wear resistance due to the attraction force. And because the coating component is a nano material, even if the thickness of the coating exceeds one micron, the visible light transmittance of the coating still exceeds 51 percent.

The transparent coating layer contains conductive inorganic nano material, so that the surface resistivity is easily less than 10¹²Omega/□. The object coated with the antistatic coating can obtain the antistatic inorganic coating after low-temperature curing, room-temperature curing or high-temperature curing, thereby obtaining the functions of electrostatic discharge and self-cleaning, and greatly reducing the dust content of the surface area. The antistatic inorganic nano-coating is suitable for coating the surfaces of bodies such as high-speed rails, motor cars, automobiles and the like, aircrafts such as gliders, unmanned aerial vehicles and the like, electronic displays such as mobile phone screens, television screens, computer screens and the like, billboards, sculptures, pictures, buildings, furniture, clothes, shoes, hats, ceramics, ceramic tiles, plastics, glass, photovoltaic panels, glasses, floors and the like, and the obtained coating is antistatic, transparent, high in adhesive force and long in outdoor life.

Moreover, to the best of the applicant's knowledge, such methods for preparing antistatic transparent inorganic nanocoating, articles, coating compositions have not been reported in academic and industrial areas.
