Description

APPARATUSES, PROCESSES, AND COMPOSITIONS FOR FACILITATING

SELECTIVELY FILTERING OF THE LIGHT

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. # 63359887, titled “APPARATUSES, PROCESSES, AND COMPOSITIONS FOR FACILITATING SELECTIVELY FILTERING OF THE LIGHT ”, filed 11 -JUL-2022, which is incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

Generally, the present disclosure relates to the field of compositions: coating or plastic. More specifically, the present disclosure relates to apparatuses, processes, and compositions for facilitating selectively filtering of the light.

BACKGROUND OF THE INVENTION

Some paints are applied to roofs of agricultural buildings, such as a greenhouse, in the summer months to provide shading and a cooling effect within the greenhouse. Usually, such paints consist of a high weight percentage of mineral pigment/filler, such as calcium carbonate powder, and a low percentage of polymeric binder. This allows the paints to be applied easily to the roofs of the greenhouse using conventional and simple application methods but also allows for the easy removal of water after the summer or as required. The disadvantage of these paints is that they act similarly to a neutral density filter, filtering out both light in the photosynthetically active region (PAR) (400-700nm) and the near-infrared region (NIR) (700-2500nm) equally. This is often undesirable as the light in the PAR is still required by the plants for increased yield, but it is chopped at the expense of removing the light in the NIR region, to avoid excessive heating within the greenhouse.

Therefore, there is a need for improved apparatuses, processes, and compositions for facilitating selectively filtering of the light that may overcome one or more of the above- mentioned problems and/or limitations.

Overview:

The present disclosure describes apparatuses, processes, and compositions for facilitating selectively filtering of the light. Further, the present disclosure describes photosynthetically active region (PAR) light enhancing additive for agricultural paints. Further, this additive is used with agricultural paints such as the common ‘chalking’ paints.

Further, the present disclosure describes a selective absorption pigment that has a high transparency in the visible region and low in the NIR region of the spectrum. This can be processed into a water-based dispersion which can then be used as an additive for the above chalking paints. When added to the paints in the correct concentration, the resulting coating that can be achieved allows for more PAR light to be transmitted for the same amount of NIR blocking vs the original chalking paints. Pigments with a high molar extinction coefficient are selected (such as dyes and nano powders) so that only a small amount needs to be added to achieve the desired effect. In addition, the small size of both nano powders and chemical dye species means that they have little to negligible effect on both the application of the paint as well as the physical properties of the coating vs the original chalking paints. Suitable materials include doped metal oxides nanoparticles such as indium tin oxide, antimony tin oxide, cesium tungsten oxide, lanthanum hexaboride, and NIR absorbing dyes.

Further, the present disclosure describes the use of selective absorbing pigments as an ‘additive’ to commercially available agriculture paints. The selective absorbing pigments are added to a pre-prepared paint and not included during manufacturing. The selective absorbing pigments allow for the added benefit of a coating with a higher PAR for the same NIR blocking properties, which leads to increased yield.

Further, the present disclosure describes the use of the selective absorbing pigments having a) a small size and b) a high molar extinction coefficient meaning that the additive has a negligible impact on the paint/coating, which means that the application (spray equipment, settings, etc.) doesn’t have to change. Further, using pigments with a small size allows them to be embedded within the matrix of the (small amount of) polymer binder of the coating and this means the physical properties/performance of the final coating aren’t affected, and it still adheres to the same and washes off the same.
