preparation example Construction

[0030] Correspondingly, the present invention also provides a preparation method of a composite film for an umbrella cover, comprising the following steps: mixing fluorescent powder with a polyurethane adhesive, and stirring to obtain a fluorescent paint; placing the fluorescent paint on a printing machine as a fluorescent ink In the process, the fluorescent paint is printed on the surface of the polypropylene film to form a fluorescent layer, and the polypropylene film is filled with hollow glass beads coated with titanium dioxide; the surface of the fluorescent layer is cast and coated with a polyurethane film to obtain an umbrella surface Composite film is used.

[0031] Wherein, the weight ratio of the fluorescent powder to the polyurethane binder is preferably 1:5-10, more preferably 1:6-8. The step of mixing the fluorescent powder and the polyurethane binder is preferably: stirring the fluorescent powder and the polyurethane binder at a weight ratio of 1:5-10 at a speed ...

[0048] Weigh 5 g of hollow glass microspheres, add them to a 500 mL four-neck flask, add 50 mL of distilled water, drop in 2 mL of 2% aqueous sodium dodecylbenzenesulfonate solution, stir, disperse, and heat up to 100°C. Adjust the pH value to 2.0-2.5 with 10% NaOH solution. Slowly add 10% Ti(SO 4 ) 2 solution, while adding dropwise a 10% NaOH solution to keep the pH value of the reaction solution. After the reaction, filter and wash the filter cake. The filter cake was dried in a blast oven at 120°C for 3h, and then calcined in a muffle furnace at 600°C for 2h to obtain TiO 2 Coated hollow glass microspheres.

[0049] in TiO 2 Add 50mL of distilled water to the coated hollow glass microspheres, stir evenly, disperse, heat up to 30-45°C, add organic surfactant trimethylchlorosilane, stir slowly, fully disperse, and then dry at room temperature to obtain two layers of surface modification hollow glass microspheres.

[0052] Fluorescent Umbrella Made by Gravure Printing

[0053] (1) Production of fluorescent umbrella surface:

[0054] Stir 50g of fluorescent powder and 300g of polyurethane adhesive at a speed of 120rpm for 15-30min, and mix uniformly to make a fluorescent paint. The fluorescent paint is put into the ink fountain of the gravure printing machine as fluorescent ink, and the ABC pattern text information is arranged under the quadrangle through the laser. The engraving is made into a gravure plate and loaded on a gravure printing machine.

[0055] The hollow microbead composite polypropylene film prepared in Example 1 with a thickness of 80-140 μm is subjected to 6000-9000 volt high-voltage corona treatment, and its surface reaches more than 39 dynes, and then the polypropylene film is used as the substrate to print the above production The pattern and text, the thickness of the ink layer of the picture and text is 20-30μm, and the printed product is ventilated and dried in an ...

Abstract

The present invention provides an umbrella surface composite film and a preparation method thereof, wherein the umbrella surface composite film comprises a polyurethane film, a fluorescent coating and a polypropylene film, and the polypropylene film is filled with titanium dioxide coated hollow glass micro-beads. Compared with the umbrella surface composite film in the prior art, the umbrella surface composite film of the present invention has the following characteristics that TiO2 is wrapped on the surface of the hollow glass micro-beads so as to provide characteristics of good near-infrared radiation reflection and heat conduction prevention and effectively reflect the thermal radiation of sunlight so as to block heat transfer, such that the fluorescent umbrella formed from the prepared umbrella surface composite film has characteristics of good infrared radiation reflection and good thermal insulation effect. Accordingly the present invention further provides the fluorescent umbrella formed from the umbrella surface composite film, wherein the fluorescent umbrella has characteristics of good infrared radiation reflection and good thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of umbrellas, in particular to a composite film for an umbrella surface, a preparation method thereof, and a fluorescent umbrella. Background technique [0002] Luminescent materials are divided into active luminescent materials and passive luminescent materials, wherein passive luminescent materials are divided into luminescent materials and fluorescent materials. Fluorescent material can be seen in fluorescent color under the excitation of the light source, and the fluorescence cannot be seen after the light source is removed, so it is often used in daytime. With the continuous improvement of people's safety awareness and living standards, in addition to the application of labor protection products and traffic instructions, the amount of fluorescent materials in daily necessities continues to expand, and has been widely used in daily necessities such as umbrellas, watches, and bags. application.
