Abstract

The double-sided two-purpose sunshade includes a sunshade fabric, a skeleton, a support rod and an arc handle in the end of the support rod. The sunshade fabric includes two layers, including one upper transparent or light colored plastic film layer and one lower Dacron fabric layer with ultraviolet shielding agent coated to the surface, with these two layers being adhered together. In rain, the plastic film can keep out rain, and in sunny day, the lower layer can shield and absorb ultraviolet ray to protect skin. The present invention has the advantages of safety, comfort, two purposes, reasonable structure, low cost and other advantages.

Description

Double-sided two-purpose sunshade umbrella

Technical field the present invention relates to a kind of side's water apparatus, especially a kind of new-type double-sided two-purpose sunshade umbrella with anti-ultraviolet function.

Technical background is since the twenties in last century, because a large amount of uses of carbon fluorine series solvent and freon, ozone layer suffers serious destruction in the earth atmosphere, the ultraviolet ray that arrives earth surface is constantly increased, ultraviolet ray is the electromagnetic wave of wavelength 180-400nm, an amount of ultra-violet radiation has bactericidal action and can promote the synthetic of vitamin D, helps health.But under the burning sun prolonged exposure, human body skin can lose resists function, easily burns, and erythema or bubble occur.Excessive ultraviolet ray irradiation also can be brought out skin disease (as dermatitis, pigment asteatosis cutis), even cutaneum carcinoma, promotes the immunologic function of cataractous generation and reduction human body.

At present, international ultraviolet-resistant fabric mainly contains three major types, i.e. coating class, chemical fibre class and textile class.Studies show that nano-TiO ₂, nano-ZnO, nanometer SiO ₂, nanometer Al ₂O ₃, nano mica, nano-sized iron oxide all have the ultraviolet feature of absorption.If a small amount of nanoparticle is added in the chemical fibre, will produce the ultraviolet radiation absorption phenomenon, thereby can protect human body not to be subjected to ultraviolet damage effectively.

Parasols is that people are used to intercept ultraviolet most important and the most general instrument in summer, but there is the bad problem of rainproof effect in most parasols of selling on the market now, one rains heavily, and phenomenons such as roof leaking appear in the umbrella cover that will drench, and therefore the effective shielding of ultraviolet of pure umbrella does not also have a kind of umbrella face material of the dual-use function that shielding of ultraviolet is combined with highly effective rainproof.Sun in summer light transmission power is strong, and rainwater is many again, is people's needs can highly effective rainproof well blocking ultraviolet umbrella again.In order to solve this class problem, we provide a kind of can block the new-type double-sided two-purpose umbrella appearance that ultraviolet ray can be prevented rainwater again.

Summary of the invention the purpose of this invention is to provide a kind of double-sided two-purpose sunshade umbrella, is used to solve the problem that common umbrella does not have waterproof and antiultraviolet double effects.

For achieving the above object, double-sided two-purpose sunshade umbrella of the present invention, comprise umbrella cover, keel frame, support bar and the circular arc handle that is installed in the support bar end, umbrella cover is divided into two-layer, the upper strata is the plastic sheeting of transparent or light colour, lower floor is a polyester fabric, and the upper surface of polyester fabric applies ultraviolet light screener, and incites somebody to action two-layer sticking together up and down with binding agent.

After adopting said structure, in rainy weather, the user can be rainproof by the plastic sheeting on umbrella cover surface, avoids health to drench; When the sun beats down, the user also can open umbrella cover, and the polyester material by umbrella cover blocks and absorbs ultraviolet ray, effectively guarantees the safety of body skin.

Advantage of the present invention is: safe in utilization comfortable, multiple functional, rational in infrastructure, cost is low, technology is simple, in light weight, can also bring into play block the ultraviolet ray and the waterproof double effects, for the user provides comfortable service condition.

Description of drawings Fig. 1 is the overall structure schematic diagram of double-sided two-purpose sunshade umbrella of the present invention.

Fig. 2 is the umbrella cover planing surface figure of double-sided two-purpose sunshade umbrella of the present invention.

The specific embodiment as shown in Figure 1, double-sided two-purpose sunshade umbrella of the present invention, comprise umbrella cover 1, keel frame 2, support bar 3 and the circular arc handle 4 that is installed in support bar 3 ends, umbrella cover 1 is divided into two-layer, the upper strata is the plastic sheeting 1-1 of transparent or light colour, lower floor is polyester fabric 1-2, and the upper surface of polyester fabric applies ultraviolet light screener, and incites somebody to action two-layer sticking together up and down with binding agent.Concrete manufacturing process of the present invention is as follows: raw material: terylene cloth 1-2, utilize the PVC plastic sheeting of surface light crosslinking technology moulding, finished product nano-TiO ₂(19nm) with ZnO (39nm) composite granule, dispersant, antisettling agent, adhesive, anti-microbial inoculum, crosslinking agent, antistatic additive, softening agent, auxiliary agents such as age resister and mill base.Production process:

1, coating is made: with nanoscale TiO ₂, the ZnO composite granule dissolves in the water, adds dispersant by following proportioning simultaneously, antisettling agent, adhesive, anti-microbial inoculum, crosslinking agent, antistatic additive, softening agent, auxiliary agents such as age resister and mill base, through shear-mixed (5000r/min) 15min, Ultrasonic Pulverization 15min sieves, process such as toning, and is stand-by.(raw material of weight (g) ratio is made: water 30～80, TiO ₂, ZnO composite granule 20～50, adhesive 10～40, dispersant 0.5～2, antisettling agent 0～4, anti-microbial inoculum 0～1, antistatic agent 0.001～0.5, age resister 0.001～0.5.)

2, coating applies: adopt padding method in the coating working solution for preparing, the terylene cloth is carried out two soak two and roll (room temperature, pick-up 70%), preliminary drying (90-100 ℃, 1.5min) bake then (150-200 ℃, 2min).

3, adhesion of plastic films: can accomplish that through the PVC plastic sheeting after the processing of surface light crosslinking technology waterproof outer is good, the internal layer cohesive is good, is convenient to carry out bonding.Utilize adhesive that ectonexine is bonding,, guarantee bonding fastness through hot-forming after-baking.

4, cutting shape is made umbrella face material.

Claims

1, a kind of two cotton two-purpose parasol, comprise umbrella cover (1), keel frame (2), support bar (3) and be installed in the terminal circular arc handle (4) of support bar (3), it is characterized in that: umbrella cover (1) is divided into two-layer, the upper strata is the plastic sheeting (1-1) of transparent or light colour, lower floor is polyester fabric (1-2), the upper surface of polyester fabric applies ultraviolet light screener, and incites somebody to action two-layer sticking together up and down with binding agent.
