Description

Technical Field

[0001] The invention relates to the technical field of coatings, and in particular to a regreening agent spray for living moss to survive the summer. Background Art

[0002] Moss plants are typical representatives of ground cover plants with delicate texture and clear color, and are widely distributed. Moss plants are evergreen all year round and are often used in outdoor landscapes. However, due to the excessive outdoor light intensity in summer and improper artificial maintenance, mosses may dry up and turn yellow, affecting their aesthetics. Even if mosses are carefully maintained, it is difficult to keep them green as required for landscapes.

[0003] When ordinary moss regreening agents available on the market are applied to moss, it takes a long time to achieve the regreening effect, generally one to two weeks, which cannot meet the immediate needs of the landscape. If green paint can be sprayed on living moss, the moss can be successfully regreened in a short time, but there is currently no green paint specifically for living moss, and ordinary paint cannot meet the needs of living moss for good air permeability and low toxicity. In addition, considering that the paint needs to be used outdoors, it still needs to have excellent properties such as water resistance and light resistance to cope with various weather changes. Pigments, as one of the main components of the paint, have a certain effect on the toxicity of the paint. Natural plant pigments have the advantages of low plant toxicity and can be a better choice for preparing moss regreening coatings, but natural plant pigments have poor color fastness and may breed bacteria, which ultimately affects the regreening effect of the moss. In view of the above problems, the present invention prepares a regreening agent spray for living moss to survive the summer, which can not only make the living moss regreen in a short time, but also has good air permeability and low toxicity, enabling the moss to grow normally, while also meeting the waterproof, light-resistant and antibacterial properties required for outdoor coating applications.

[0030] Comparative Example 1 A regreening agent spray for living moss to survive the summer, which differs from Example 1 only in that no rutile titanium dioxide powder is added to the ingredients of the regreening agent, and other ingredients and addition amounts are the same as those in Example 1, and the preparation steps and use methods are the same as those in Example 1.

[0031] Comparative Example 2 A regreening agent spray for living mosses to survive the summer, the only difference from Example 1 is that the rutile titanium dioxide powder added to the components of the regreening agent is an ordinary spherical powder with a particle size of 3 μm, the other components and addition amounts are the same as those in Example 1, and the preparation steps and usage methods are the same as those in Example 1.

[0032] Comparative Example 3 A regreening agent spray for living mosses to survive the summer, the only difference from Example 1 is that the pigment added to the components of the regreening agent is KN-5200 green metal complex dye produced by Shanghai Wangchong Chemical Co., Ltd., the other components and addition amounts are the same as those in Example 1, and the preparation steps and usage methods are the same as those in Example 1.

[0033] Comparative Example 4 A regreening agent spray for living moss oversummering, which differs from Example 1 only in that no isothiazolinone antibacterial agent is added to the ingredients of the regreening agent, and other ingredients and addition amounts are the same as those in Example 1, and the preparation steps and use methods are the same as those in Example 1.

[0034] Experimental methods The greening agent prepared in the comparative example and the example was evenly coated on the surface of the pretreated substrate, and then cured at room temperature (temperature 20°C, relative humidity 50%) for 72 hours, and a 10mm×70mm×5mm film was made with a mold and used for the following test.

[0035] Air permeability: Set the instrument temperature to 25℃ and the relative humidity to 50%, then place the sample on a permeable cup filled with about 50mL of distilled water, sealed with a neoprene ring and fixed with screws. The test assembly is placed in the instrument, and the weight loss of distilled water is measured regularly to obtain the air permeability, where the unit of the weight loss of distilled water is kg; the unit of the thickness of the membrane is m; the time interval between measurements is (24×3600) s; p is the saturated vapor pressure of water at 25℃, i.e. 3169 Pa.

[0036] Waterproof property: The comparative example and the example were respectively coated evenly on a clean glass slide to form a film, and after being placed at room temperature (temperature 20°C, relative humidity 50%) for 72 hours, the coated glass slide was immersed in distilled water for 24 hours, and the water absorption was calculated after accurate weighing.

[0037] Antibacterial property: (1) Inoculate Penicillium on potato-glucose-agar medium and culture in a 37°C biochemical incubator for 16 h. Pick a single colony and use 0.9% sterile sodium chloride injection to make a bacterial suspension. Dilute the suspension to a concentration of 5 × 10 7 CFU / ml for later use. Cut the membrane into small discs with a diameter of 1 cm for later use.

[0038] (2) Mix 20 ml of unsolidified potato-glucose-agar medium sterilized at 40-45°C with 100 µL of diluted Penicillium solution and pour into the plate. After the medium solidifies, place the coating disc sample parallel to the medium, press the sample lightly to make the sample fit tightly with the medium, and cover the plate. Incubate the above plates at 33°C for 24 hours under visible light and no light, and observe whether there is an antibacterial ring; select the antibacterial ring with uniform and sterile growth, measure its diameter with the outer edge of the antibacterial ring as the boundary and record it, and calculate the average value. The diameter of the antibacterial ring = the diameter of the antibacterial ring (including the coating sample) - the outer diameter of the coating sample.

[0039] Gloss: Use a gloss meter to measure the gloss of the coating surface at 45° to determine the gloss of the coating film.

[0040] Lightfastness: Tested in accordance with GB / T 9757-88 and rated according to the standard.

[0041] Survival of moss: The regreening agent prepared in Examples 1 to 3 and Comparative Examples 1 to 3 was sprayed on healthy living mosses with an area of ​​10 cm×10 cm by using the observation measurement and diary recording method. The survival of the moss was observed and recorded regularly every day for 50 days.

[0042] The test results are shown in Table 1 and the instruction manual. Figure 1~2 .

[0043] Table 1 Performance test results of Examples 1 to 3 and Comparative Examples 1 to 4 Table 1 shows the performance test results of Examples 1-3 and Comparative Examples 1-4.

[0044] The air permeabilities of Examples 1 to 3 and Comparative Examples 3 and 4 are higher than those of Comparative Examples 1 and 2. Specifically, the reason for being higher than that of Comparative Example 1 is presumably that the needle-shaped rutile titanium dioxide powder added in Examples 1 to 3 and Comparative Examples 3 and 4 establishes a scaffold-like structure in the coating, thereby generating micropores, and the addition of two powders with different particle sizes to the emulsion can reduce powder agglomeration, increase the porosity and uniformity of the coating, and make the coating have better air permeability; although titanium dioxide powder is added to Comparative Example 2, the structure of the powder is an ordinary spherical structure with the same particle size, and it is presumed that a scaffold-like structure cannot be established, and the generated micropores are smaller, so the air permeability is lower than that of Examples 1 to 3 and Comparative Examples 3 and 4.

[0045] The water absorption rate reflects the waterproofness of the coating. The lower the water absorption rate, the better the waterproof effect of the coating. The main reason why the present invention selects water-based silicone acrylic emulsion as the main raw material is that the silicone acrylic emulsion itself has a certain waterproofness. The reason why the water absorption rate (≤20%) of Examples 1 to 3 and Comparative Examples 3 and 4 is lower than that of Comparative Example 1 is that Examples 1 to 3 and Comparative Examples 3 and 4 also add rutile titanium dioxide powder, and its own hydrophobicity blocks water droplets and keeps them on the surface of the coating, thereby enhancing the waterproofness of the coating; the reason why it is lower than that of Comparative Example 2 is speculated to be that the powders in Examples 1 to 3 and Comparative Examples 3 and 4 are needle-shaped structures and the particle sizes selected are different. The smaller particle size of titanium dioxide can act as a bridge for the larger particle size of titanium dioxide, and the two are more closely connected, thereby further reducing the water absorption rate and improving the waterproofness of the coating.

[0046] The larger the diameter of the antibacterial ring, the better the antibacterial property of the coating. Under visible light irradiation conditions, the antibacterial properties of Examples 1 to 3 and Comparative Example 3 (antibacterial ring diameter ≥ 15.9 mm) are better than those of Comparative Example 1 because the rutile titanium dioxide powder added in Examples 1 to 3 and Comparative Example 3 has an antibacterial effect, and its excellent photocatalytic performance can convert water and oxygen into active oxygen such as free radicals, thereby destroying the cell structure of bacteria; the reason why it is better than Comparative Example 2 is that the titanium dioxide powder added in Examples 1 to 3 and Comparative Example 3 is a needle-shaped structure, and its specific surface area is larger than that of ordinary spherical powder, and it is easier to perform photocatalysis, so it has better antibacterial properties; under lightless conditions, the antibacterial effects of Examples 1 to 3 and Comparative Examples 2 to 3 are better than those of Comparative Example 4 because the isothiazolinone antibacterial agents added in Examples 1 to 3 and Comparative Examples 2 to 3 effectively improve the antibacterial effect of the coating under lightless conditions. It can be seen that the coating prepared by the present invention has certain antibacterial properties under both light and lightless conditions, and can meet the survival of living moss in outdoor environments.

[0047] The reason why the glossiness of Examples 1 to 3 and Comparative Examples 3 and 4 is lower than that of Comparative Example 1 is that the needle-shaped titanium dioxide powder added in Examples 1 to 3 and Comparative Examples 3 and 4 has a certain matte property and can reduce the glossiness of the coating. In addition, the glossiness of Comparative Example 2 is higher than that of Examples 1 to 3 and Comparative Examples 3 and 4, indicating that the addition of needle-shaped titanium dioxide powder with different particle sizes can improve the matte effect to a certain extent, thereby making the coating covered on the living moss look more real and making the living moss more ornamental.

[0048] The light resistance of Examples 1 to 3 and Comparative Examples 3 and 4 is better than that of Comparative Example 1. After high-intensity ultraviolet irradiation, there is no fading, blistering or cracking. The reason is that the rutile titanium dioxide added in Examples 1 to 3 and Comparative Examples 3 and 4 has a high refractive index and ultraviolet absorption capacity, which can not only reduce the direct exposure of light to the coating, but also effectively absorb ultraviolet rays, thereby reducing the damage of light to the coating, delaying aging, and increasing the light resistance of the coating; the reason why it is better than Comparative Example 2 is that the needle-shaped rutile titanium dioxide powder has a larger specific surface area than ordinary spherical powder, and its refractive index is higher, the ultraviolet absorption capacity is stronger, and the light resistance is also better.

[0049] By observing the survival of the living moss after spraying the coating, it was found that the living moss of Comparative Example 1 died on the 8th day. It is speculated that the reason is that titanium dioxide powder was not added in Comparative Example 1, and the air permeability of the coating was very poor, causing the moss to die due to lack of oxygen; although titanium dioxide powder was added in Comparative Example 2, it is speculated that the air permeability of the coating prepared by the spherical structure powder did not fully meet the survival requirements of the living moss, so the living moss also died after 32 days of survival; the metal pigment added in Comparative Example 3 has strong phytotoxicity, but the leaves of moss plants generally have only a single layer of cells and no protective layer, so the moss cannot survive in such an environment and died quickly on the 3rd day of survival; observing the survival of the living moss of Examples 1 to 3, it can be more intuitively explained that the coating prepared by the present invention can ensure the normal growth of the living moss and will not cause its death.

[0050] Figure 1 This is the finished product of the regreening agent prepared in Example 1. As can be seen from the figure, the prepared regreening agent has good stability and uniform color dispersion, which is conducive to the stable storage of the regreening agent.

[0051] Figure 2 This is a picture showing the effect of spraying the living moss with Example 1. As can be seen from the figure, the prepared regreening agent is sprayed on the living moss, the color is sprayed evenly, the sprayed living moss has a lower glossiness, looks more real, and has better ornamental value.

[0052] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention.
