Abstract

The invention discloses a glass sun-shading agent which is formed by metal oxide nanomaterials such as tin, tungsten, copper, iron and zinc and various water-dilutable resin inorganic binders. The sun-shading agent can be directly sprayed on the surface of glass through an air sprayer pistol. Because the sun-shading agent contains Mg-Si sol, the agent can be firmly combined with the glass(building glass and automobile glass) after the agent is cured to become film, has the advantages of structural durability, no frothing, no warping and high scrub resistance, etc., and has the service life as long as more than ten years. The products of the invention have the function of automatic frequency selection, can effectively reflect and prevent the infrared which produces heat, can let visible light pass through without prevention, prevent most solar heat outside a room, and reduce the indoor temperature and the electricity consumption of an air conditioner, which not only saves the energy but also does not influence lighting and viewing effects. Moreover, compared with coated glass, the glass with the sun-shading agent has higher transmission and can not generate light pollution to outdoor environment.

Description

Glass sunscreen and preparation method thereof

Technical field

The present invention relates to a kind of water-miscible paint, particularly relate to a kind of building glass and vehicle glass sunscreen and preparation method thereof.

Background technology

Well-known sunlight can be divided into UV-light (200-380nm), visible light (380-780nm), infrared light (780-4000nm), and the most arrival ground solar infrared light near-infrared region of all concentrating 780-1500nm.Building glass commonly used is that full impregnated is bright at the 200-5000nm wave band, and the above infrared rays of 5000nm is directly to pass through glass, and is opaque fully.In order to stop solar ultraviolet by usable reflection, people are at covering one deck light-permeable barrier on glass, this barrier is generally a kind of composite plastic film (as: pad pasting or plated film), it is that form with a kind of film exists, when needs, again it is sticked on glassly, use inconvenient, and its work-ing life is shorter, uses only several years.

Summary of the invention

One object of the present invention be to provide a kind of durable in use, non-foaming, do not roll up skin, high scrubbable glass sunscreen.

Another object of the present invention is to provide a kind of preparation method of glass sunscreen.

For achieving the above object, technical solution of the present invention is:

A kind of glass sunscreen preparation method may further comprise the steps:

(1) in water, adds quantitative nanometer tungsten oxide tin, nano-sized iron oxide, Sodium hexametaphosphate 99 successively, prepare the aqueous solution of Sodium hexametaphosphate 99 of nano-sized iron oxide, the 0.005-0.015% of nanometer tungsten oxide tin, the 0.8-8% of a kind of 1-10% of containing, in the sand mill, grind more than 20 hours;

What (2) add 1-20% again contains the magnesium silicon sol, continues to grind 2 hours, takes out the back and filters with 400 purpose fine-structure meshes;

(3) add organosilicon acrylic resin, pure third resin of 5-15%, the 0.1-0.5% wetting agent of 10-30% again, high-speed stirring 2 hours refilters with 400 order fine-structure meshes;

(4) thickening material with 0.1-1% is adjusted to d spiss, adds the film coalescence aid of 0.5-5%, slowly stirs more than 12 hours, promptly finishes.

After adopting such scheme, the present invention is a kind of water-based emulsion, and it is made up of nano-metal-oxide such as tin, tungsten, copper, iron, zinc and multiple water-base resin mineral binder bond.It is available to have gas spray gun to be painted on glass surface.Because it contains the magnesium silicon sol, behind the film-forming can with the glass mortise, have durable in use, non-foaming, do not roll up advantages such as skin, high scrubbing resistance, can reach the more than ten years work-ing life.Product of the present invention also has the automatic frequency selection function, can stop the infrared rays that produces heat by usable reflection, and can allow visible light is almost unobstructed to be passed through, be blocked in most of sunlight heat outdoor, reduce room temp, reduce air conditioning electricity, so both saved energy, can not influence daylighting and view effect again.In addition, the present invention compares with coated glass, and the perspective rate is higher, can not produce light pollution to outdoor environment.

The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
