The invention provides a hard coating film to solve the problem of film cracking or curling. The technical proposal is that: the hard coating film comprises a support body and a hard coating; the hard coating has the compositions and weight portions as follows: 20 to 90 portions of UV curing acrylate, 2 to 20 portions of thermoplastic resin, 2 to 15 portions of photoinitiator, 0.2 to 15 portions of silicone, and 10 to 90 portions of solvent. The invention can inhibit cracking or curling caused by curing shrinkage, prohibit fingerprints or dusts, etc. from attaching on the surface of the film where attached fingerprints and dusts can be easily wiped off, and maintain the scratch resistance and wear resistance of the hard coating film.

The invention relates to a printing adhesive of stone paper wallpaper and a preparation method of the printing adhesive. The printing adhesive is a polymer emulsion which is prepared by carrying out emulsion polymerization on fatty alcohol-polyoxyethylene ether (PeregalO-25), lauryl sodium sulfate, methyl acrylate, ethyl acrylate, epoxypropyl methacrylate, vinyl acetate, methyl methacrylate, acrylic acid, 1-(2-Methacryloyloxyethyl)-2-imidazolidinone, ammonium persulfate, sodium hydrogen sulfite and deionized water. The printing adhesive has the advantages of good environmental friendliness property, high adhesion fastness, good color fastness, contamination resistance as well as dry wiping and wet wiping resistance.

The invention discloses an LED-UV (light-emitting diode-ultraviolet) anti-doodling pollution-resisting coating, which can be used to coat the surface, which is polished and cleanly dedusted in advance, of a to-be-coated object through brush coating or spray coating according to the coating weight to 80g / m<2>; photocuring is performed immediately through illuminating by a portable LED-UV lamp for 5 to 8 seconds after the brush coating is finished; the LED-UV anti-doodling pollution-resisting coating is prepared from the following components in parts by weight: 25 to 35 parts of 4.5 functional silicofluoride acrylate resin, 21 to 30 parts of low-energy cured special functional acrylic resin, 10 to 20 parts of 8 functional hyperbranched polyester acrylic resin, 20 to 25 parts of monomer, 4 to 5 parts of photoinitiator, 0.3 to 0.5 part of wetting dispersant, 0.3 to 0.5 part of defoamer and 0.6 to 0.8 part of anti-doodling additive; a paint film has excellent properties of anti-doodling, pollution prevention, easiness in cleaning, water proofing, oil resistance and chemical resistance; the paint film is compact and smooth, and is high in hardness and good in pollution tolerance.

The invention relates to an anti-channel conflict code-spurting printing ink and its preparation method. The invention firstly provides a code-spurting printing ink. Weighed according to the gross weight of the code-spurting printing ink, it is composed of the following raw materials of: by weight, 0.1-0.8% of a colorless organic fluorescent coloring agent, 2-10% of an organic solvent soluble dye, 1-10% of polymer resin and 80-90% of an organic solvent. The invention also provides a preparation method of the above code-spurting printing ink. The code-spurting printing ink provided by the invention remains properties and functions of a common printing ink, and is also endowed with a certain anti-channel conflict, anti-tamper and anti-counterfeit hiding performance, thus effectively hitting counterfeiters, increasing difficulty in counterfeiting to a large extent and avoiding further forgery. Simultaneously, according to the code-spurting printing ink, plain code and secret code jet printing can be realized only with an inkjet printing machine. Therefore, it is not necessary for manufacturers to increase new inkjet printing machines for secret code jet printing, thus greatly simplifying production process and saving production cost.

The invention discloses a warm simple clean kitchen ventilator, which is characterized by the following: comprising casing, fan, smoke discharging pipe and retainer; setting the casing as inner casing and shell; arranging heat-insulating layer near casing and insulating layer near inner casing in the casing; arranging electric-heat wire between the insulating layer and the heat-insulating layer; using heat from the electric-heat wire; turning viscous oily soil on inner wall to scattered; generating flowability; flowing to collecting oil cup on the kitchen ventilator; cleaning the oily soil without hot water and chemical detergent.

The invention discloses a portable anti-scattering ink bottle, which belongs to a cultural article, and is mainly composed of an ink bottle body, an ink taking device, and a bottle cap, and is characterized in that an inlet and outlet pipe 4 is fixed on the ink taking device 2, After the inner screw thread 6 is tightened, the inside of the ink bottle can be sealed, and the air or ink is only discharged and sucked through the inlet and outlet pipe 4; the bottle body is made of plastic or metal, and the middle part of the bottle body is relatively thin, which can be recessed inward under the pressure of the hand , change the air pressure in the bottle, and quickly return to the original shape after the hand is loosened. The main part of the ink taking device 2 has a two-layer cup body structure, the lower cup body has a bottom, the air pressure of the bottle body is increased, and the ink discharged through the inlet and outlet pipe 4 is retained here for use by fountain pens and dip pens; the cup-shaped guard plate 5 , when the pen absorbs water, it is convenient to support the pen body, and when the ink bottle is tipped over, it prevents the ink from spilling out. The upper edge of the ink taking device 2 is inlaid with a circle of soft sponge 8, which is convenient to wipe off excess ink from the nib, and avoids thick and sometimes thin handwriting when writing; the dustproof bottle cap 3, the bottle body will not discharge ink even after the cap is tightly closed , can be convenient for students to carry on the way. The invention has a simple structure, is especially suitable for injection molding, is easy to produce, and is convenient and practical.

The invention provides supramolecular perfluorinated gel and a preparation method thereof. The preparation method comprises the following steps: taking an anisotropic porous polytetrafluoroethylene film, dropwise adding a perfluoro solution to the surface of the anisotropic porous polytetrafluoroethylene film, observing the transparency of the anisotropic porous polytetrafluoroethylene film at thesame time, stopping dropwise addition when the transparency of the anisotropic porous polytetrafluoroethylene film does not change any more, and then subjecting the anisotropic porous polytetrafluoroethylene film to standing for 6-72 hours to obtain the porous polytetrafluoroethylene film. The gel can effectively solve the problems of complex calendering operation process and no antibacterial property of existing gels.
