Abstract
The utility model relates to a can prevent waterborne synthetic leather of fracture, include and follow supreme non -woven fabrics substrate layer of laminating in proper order, waterborne polyurethane foaming layer and fluorine -containing waterborne polyurethane layer down it has a near -infrared barrier layer to coat between waterborne polyurethane foaming layer and the fluorine -containing waterborne polyurethane layer the upper surface on the fluorine -containing waterborne polyurethane layer ultraviolet absorption layer that has then coated, and be in the upper surface on ultraviolet absorption layer has still coated one self -cleaning layer. The utility model discloses a surface is provided with nanometer rutile titanium dioxide coating, and it reaches 95% to the ultraviolet absorption rate, effectively separation ultraviolet ray to still be provided with nano meter tin dope cadmium oxide coating, its near -infrared separation rate to the wavelength is less than 1200nm reaches 85%, and effective separation far infrared can effectively reduce the condition of fading, ftractureing because of the synthetic leather surface is aroused by ultraviolet ray and near infrared irradiation for a long time.
Description
Technical field
This utility model relates to technical field of synthetic leather, particularly relate to a kind of can the Waterborne synthetic leather of crack resistence.
Background technology
Synthetic Leather divides similar mutually due to the Nomenclature Composition and Structure of Complexes to natural leather, has now been widely used in the goods such as footwear, bag, clothing.The Synthetic Leather relatively early occurred is solvent borne polyurethane synthetic leather, and containing organic solvents such as methylformamide, toluene, butanones, environment is produced serious pollution by these solvents, prevents development and the application of molten Ji type polyurethane synthetic leather.Existing market has occurred in that a lot of waterborne polyurethane synthetic leather, due to without or containing minimal amount of organic solvent, comparison is safe and environment-friendly.But, the uvioresistant of the waterborne polyurethane synthetic leather on existing market, anti-far infrared performance are relatively poor, after being made into leather shoes, fur clothing, are exposed to the sun through the long sun, it is easy to fade, ftracture.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of can the Waterborne synthetic leather of crack resistence.
For realizing above-mentioned technical problem, the solution that this utility model is taked is: a kind of can the Waterborne synthetic leather of crack resistence, including the nonwoven fabric base sheet material layers fitted successively from bottom to up, waterborne polyurethane foaming layer and fluorine-containing aqueous polyurethane layer, a near-infrared barrier layer it is coated with between described waterborne polyurethane foaming layer and fluorine-containing aqueous polyurethane layer, upper surface at described fluorine-containing aqueous polyurethane layer is then coated with a UV-absorbing layer, and is also coated with a self-cleaning layer at the upper surface of described UV-absorbing layer.
Improve further: described near-infrared barrier layer includes nano oxidized tin dope cadmium oxide coating.
Improve further: described UV-absorbing layer includes nm-class rutile-type TiO 2 coating.
Improve further: described self-cleaning layer includes Superhydrophilic nano self-cleaning coat.
nullBy adopting preceding solution，The beneficial effects of the utility model are: the particular design of each level order of this utility model is to draw through repetition test，It it not simple superposition，The surface configuration of this synthetic leather has nm-class rutile-type TiO 2 coating，Ultraviolet absorbance is reached 95% by it，Can effectively intercept ultraviolet，And also it is provided with nano oxidized tin dope cadmium oxide coating，The wavelength near-infrared rejection rate less than 1200nm is reached 85% by it，Can effectively intercept far infrared，This synthetic leather adopts double-deck Gradient Absorption，Ultraviolet and near infrared different-waveband can be respectively provided with the shielding properties of excellence，It is effectively reduced because of synthetic leather surface for a long time by fading that ultraviolet and near infrared ray irradiate and cause、The situation of cracking，This synthetic leather is additionally provided with self-cleaning layer simultaneously，Superhydrophilic is utilized to enable water to the rapid drawout on surface，Water membrane is formed between water and pollutant，Pollutant can be pulled away along with sprawling of water，Thus playing the self-cleaning function of excellence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
nullWith reference to Fig. 1，This utility model embodiment disclose be，A kind of can the Waterborne synthetic leather of crack resistence，Including the nonwoven fabric base sheet material layers 1 fitted successively from bottom to up、Waterborne polyurethane foaming layer 2 and fluorine-containing aqueous polyurethane layer 3，A near-infrared barrier layer 4 it is coated with between described waterborne polyurethane foaming layer 2 and fluorine-containing aqueous polyurethane layer 3，Described near-infrared barrier layer 4 selects nano oxidized tin dope cadmium oxide coating in the present embodiment，The effect intercepting far infrared is very good，Upper surface at described fluorine-containing aqueous polyurethane layer 3 is then coated with a UV-absorbing layer 5，Described UV-absorbing layer 5 selects nm-class rutile-type TiO 2 coating in the present embodiment，Can effectively intercept ultraviolet，And it is also coated with a self-cleaning layer 6 at the upper surface of described UV-absorbing layer 5，Described self-cleaning layer 6 selects Superhydrophilic nano self-cleaning coat in the present embodiment，There is the self-cleaning effect of excellence.
nullBy adopting preceding solution，The beneficial effects of the utility model are: the particular design of each level order of this utility model is to draw through repetition test，It it not simple superposition，The surface configuration of this synthetic leather has nm-class rutile-type TiO 2 coating，Ultraviolet absorbance is reached 95% by it，Can effectively intercept ultraviolet，And also it is provided with nano oxidized tin dope cadmium oxide coating，The wavelength near-infrared rejection rate less than 1200nm is reached 85% by it，Can effectively intercept far infrared，This synthetic leather adopts double-deck Gradient Absorption，Ultraviolet and near infrared different-waveband can be respectively provided with the shielding properties of excellence，It is effectively reduced because of synthetic leather surface for a long time by fading that ultraviolet and near infrared ray irradiate and cause、The situation of cracking，This synthetic leather is additionally provided with self-cleaning layer simultaneously，Superhydrophilic is utilized to enable water to the rapid drawout on surface，Water membrane is formed between water and pollutant，Pollutant can be pulled away along with sprawling of water，Thus playing the self-cleaning function of excellence.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; implement this technical scheme method and approach is a lot; the above is only preferred implementation of the present utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
