TWM575284U - Super hydrophobic and solar heat gain control umbrella - Google Patents

Abstract

The patent proposes an insulated umbrella with no water droplets for controlling solar energy, which has a nano-hydrophobic layer on the outer layer of the umbrella fabric, an elastic water-resistance anti-ultraviolet layer on the inner layer of the umbrella fabric, and a transparent solar heat insulation layer under the anti-ultraviolet layer. The patented super hydrophobic and solar heat gain control umbrella has the function of not leaving water droplets and effectively blocking ultraviolet rays and near infrared rays.

Description

No water droplets, sunlight control, insulated umbrella

The novel patent is a functional umbrella cloth structure design composed of a plurality of nano materials, in particular, a super-hydrophobic structure of the umbrella surface, and solar thermal energy control with ultraviolet light resistance and near red line absorption nano material doping in the umbrella cloth. umbrella.

Some common rainy umbrellas have been applied to the umbrella surface to make the umbrella surface smooth and water-free, so that it is convenient to collect water after the umbrella to facilitate indoor access. The anti-ultraviolet treatment and the opaque layer are insulated under the umbrella surface. Most of the commonly used umbrella cloth water treatments use fluorine-based polymer waterproofing agent to form a film on the umbrella surface by low-concentration dip dyeing, and then dry and solidify. However, the adhesion of the fluorine material to the substrate Very poor, most of the fluorine coating can not stay in the umbrella surface under normal use, and the water-repellent effect of the umbrella surface is greatly reduced. In addition, the fluorine material is a kind of toxic chemical that is not friendly to the global environment. Improper dosage or incorrect method can cause great harm to the human body and the environment.

In the existing anti-ultraviolet and opaque layer insulation treatment of the umbrella surface, a layer of ultraviolet absorber is applied under the umbrella surface, and the heat dissipation treatment is to apply a layer of white ceramic (alumina, zinc oxide or under the umbrella surface). Titanium dioxide coating or silver aluminum coating is expected to achieve thermal insulation by reflecting sunlight, but the effect is limited and the manufacturing cost is greatly increased and the life of the umbrella is increased. The main reason is that this heat-dissipating coating needs to have a considerable thickness to appear white or silver. Appearance, and the doping material in the coating is ceramic particles or metal particles, so that the coating becomes quite hard, which is in sharp contrast with the softness and tension of the original umbrella cloth. Therefore, the heat dissipation coating is applied. The layer is combined with the existing umbrella cloth, and it is easy to cause the heat-dissipating coating to crack in the ceramic or metal particle coating due to the strong umbrella surface tension stress in normal use, thereby affecting the appearance and performance.

In view of the above-mentioned existing problems and methods, the present invention has been developed through continuous trial and modification to develop a superhydrophobic coating of a non-fluorinated material system combined with a combination of a highly elastic ultraviolet absorbing layer and a transparent near infrared absorbing layer. The umbrella surface is highly hydrophobic, and there is no water residue remaining when the umbrella is folded, and the penetration of solar radiation heat energy can be largely blocked when used in sunlight.

The main purpose of the new patent is to make use of the super-hydrophobic property on the umbrella surface so that the water droplets do not wet the umbrella surface when it rains, and there is no water droplets remaining on the umbrella cloth to wet the room when the umbrella is closed. And by completely isolating the ultraviolet rays and the near-infrared rays in the sunlight, the sunlight under the umbrella penetrates the heat energy to be controlled, and the purpose of heat insulation is achieved.

In order to achieve the above purpose, the outer layer of the umbrella cloth fiber of the patent is a high-density decane material, and the surface of the umbrella cloth is superhydrophobic by adjusting the combination of the amount of methyl groups in the structure of the decane material and the structure of the umbrella cloth, and because The decane material and the umbrella cloth fiber have chemical bond grafting, which can greatly increase the adhesion of the superhydrophobic coating and increase the service life of the superhydrophobic material. The inner layer of the umbrella cloth fiber is a waterproof elastic ultraviolet absorbing layer, thereby blocking the UVA and UVB ultraviolet rays in the sunlight by the high weather-resistant ultraviolet absorbing layer. A transparent near-infrared absorbing layer is coated under the ultraviolet absorbing layer, and ceramic oxide is used as a key material of the layer, and the ceramic material is used. The riceting process gives the coating a transparent and near-infrared-barrier effect in the visible light band. When the lower layer of the canopy is used, only a very thin coating is required to completely block the near-infrared rays, so that the coating is not affected by the umbrella cloth. Premature deterioration due to the influence of fiber elastic tension.

FIG. 1 is a schematic view showing the upper and lower coatings of the umbrella cloth of the water-free sunlight control heat insulating umbrella of the present embodiment.

The specific embodiment of the present invention is described below with reference to the first drawing. The present invention uses nylon or polyester as the fabric of the umbrella fabric (100), and the methyl group is coated with the methyl group on the outer layer of the umbrella fabric (100). The naphthenic coating forms a nano superhydrophobic layer (11). The high weather resistant ultraviolet absorber is mixed with a polyester type resin, and uniformly coated on the inner layer of the umbrella cloth fiber (100) to form an elastic water resistant ultraviolet resistant layer (12). A coating containing a nano ceramic heat insulating material is applied under the ultraviolet resistant layer to form a transparent near infrared absorbing layer (13). The particle size distribution of the nano ceramic heat insulating material needs to be between 50 nm and 350 nm.

In this way, the creation of the water-free sunlight control umbrella is completed in the above manner, which can effectively block the ultraviolet rays and the near-infrared rays in the sunlight, and greatly reduce the temperature under the umbrella. Moreover, by the super-hydrophobic effect of the canopy surface, the water droplets can be left without leaving the remaining umbrella surface to keep the umbrella surface dry.

In summary, the present invention is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any simple modification, equivalent change, and modification to the above embodiments in accordance with the technical spirit of the present invention are It still falls within the scope of the patented technical solution.

The new patent is in line with the needs of industrial development in terms of structural design, practicality and cost-effectiveness. It is novel, creative and practical, and meets the requirements of relevant patent requirements for utility models.
