Description

Durable ultraviolet radiation resistant curtain fabric and manufacturing method thereof
Technical Field
The invention relates to the technical field of curtain fabrics, in particular to a durable ultraviolet radiation resistant curtain fabric and a manufacturing method thereof.
Background
In order to provide a good anti-uv effect for most window shades, several layers of coatings are usually prepared on the surface of the base fabric, these coatings usually consist of several substances such as acrylic resin, polyurethane, inorganic filler, carbon black, polymer auxiliary agent, etc. since the coatings usually use polymer as carrier, the aging phenomenon is inevitably generated during the use process.
The photo-aging of the polymer is the result of a series of complex reactions under the participation of ultraviolet rays and oxygen, so the process is also called photo-oxidation or oxidative photodecomposition, the photo-oxidation process is generally regarded as an auto-oxidation process initiated by light energy and consists of an initiation process, a transfer process and a termination process, and at present, adding a proper light stabilizer into a coating is an effective method.
Common light stabilizers can be classified as: a light shielding agent, an ultraviolet light absorber, a quencher and a radical scavenger.
Light-shielding agent: the light shielding agent can play a role of shielding between the polymer and light radiation, the refraction part can generate damaged light waves to the polymer, and plays a certain role of protecting the polymer in the coating, and the substances generally comprise titanium dioxide, zinc oxide, carbon black and the like, wherein the substance with the best shielding effect is nano-scale titanium dioxide, the particle size of the nano-scale titanium dioxide is small, the specific surface area of the nano-scale titanium dioxide is large, the nano-scale titanium dioxide has good ultraviolet absorption and reflection capacity, and the nano-scale titanium dioxide can be used as a shielding layer of ultraviolet rays. The defects are obvious, the nano titanium dioxide is usually added into a polymer coating in a filling mode, and the nano titanium dioxide is high in photocatalytic activity and can aggravate the aging of the polymer coating, so that the nano titanium dioxide can only resist the damage of an inner base material of ultraviolet radiation and does not have a protection effect on the coating, and after the nano titanium dioxide is used for a period of time, the curtain surface coating can be obviously pulverized to influence the use appearance;
ultraviolet absorber: the substances are also called light stabilizers, can absorb ultraviolet light parts (usually with the wavelength of 290-400nm) in a solar energy or fluorescent light source to change the ultraviolet light parts into an excited state, and then release the radiation energy parts in the form of heat energy based on tautomers without damaging the structure of the ultraviolet light parts;
when the coating material is selected, the polyurethane has good weather resistance, but is usually solvent-based, and is not environment-friendly, the cost of the silicon rubber is too high, and the silicon rubber is not beneficial to commercial production, compared with the water-based acrylic acid, the water-based acrylic acid is environment-friendly, has low cost, and has no advantages over the former two in weather resistance, but can obtain good coating performance through modification;
in the prior art, a nano-scale titanium dioxide modified polymer coating is mostly used to achieve an excellent ultraviolet shielding effect, but the coating is aged and has a short service life, so that two indexes of ultraviolet resistance of a curtain and the service cycle of the coating are difficult to obtain.
