The present invention is environmentally friendly by separating urushiol from lacquer and mixing it with inorganic paints, and has excellent adhesion to the substrate, weather resistance, heat resistance, abrasion resistance, pollution resistance, water resistance, chemical resistance, antimicrobial activity, electromagnetic shielding, excellent insulation, and lacquer. The present invention relates to an inorganic coating composition containing urushiol, which has a beautiful color, has a short manufacturing time, and has a simple coating process.
Artificial chemicals contain substances that are harmful to the environment and the human body, causing various diseases and allergic reactions, and are not easily decomposed in the ecosystem, and thus have harmful effects due to environmental pollution. Therefore, a variety of environmentally friendly products are produced by obtaining lacquer from lacquer rather than artificial chemical reactions.
Lacquer has been used for a long time, using household items applied to tableware and closets, and its properties such as stability, flame resistance, heat resistance, water resistance, antiseptic, insect repellency, insulation and antibacterial properties have been confirmed. In addition, among the objects excavated from the ruins of the past are lacquered on the surface of those preserved in its original form, it has excellent physical properties as a natural paint, the scope of application of the product is infinite.
The lacquer contains urushiol, water, monosaccharides and polysaccharides, and a small amount of enzyme. The main component of the lacquer coating is known as urushiol having a phenol group. Hardening of the lacquer requires a relative humidity of 80% and a temperature of about 30 ° C.
In addition, since moisture and oxygen are in contact with each other to cure by oxidizing urushiol, a thick coating film cannot be obtained and is manufactured through a repeated process of painting and curing. Through such a repetitive process, impurities such as dust in the air may be buried, which makes it difficult to maintain cleanliness of the workplace.
In addition, since the lacquer is hardened only by moisture and oxygen, there are many storage problems. However, although there are various problems as described above, due to the superior properties that artificial chemicals do not have, for example, due to natural materials, appearance beauty, color of natural beauty, solvent resistance, heat resistance, fire resistance, antibacterial property, chemical resistance and durability, Research has been conducted on various patents and products.
In Korean Patent No. 0631489 (name of the invention: a method of manufacturing raw chil using lacquer extract), a lacquer bark is reacted under an atmosphere of nitrogen using an organic solvent to obtain a lacquer extract, which is filtered and concentrated again to obtain urushiol, rubber and Disclosed is a method for separating glycoproteins, concentrating in vacuo and recombining them.
However, since the patent undergoes a long time of separation and concentration under a nitrogen atmosphere, the process is complicated and there is a problem that it is difficult to mass produce. In addition, purified lacquer by recombination is not different except that only impurities are removed from the raw lacquer.
Korean Patent No. 0477932 (name of the invention: Recombinant Lacquer Paint and its manufacturing method) discloses that natural lacquer is separated and recombined according to its constituents and subjected to enzyme polymerization to improve uniformity, workability and economy of quality.
However, the patent requires that the curing conditions require a relative humidity of 70% and a temperature of 20 ° C or more, as in the case of the lacquer to date, the manufacturing process is complicated, such as separation and polymerization, the change of gloss, the wrinkles of the coating film according to the curing conditions Generation, adsorption of dust due to slow curing, etc., causes mass production and difficult work for the general public.

However, the patent requires a special device, for example, bubble column reactor, takes a lot of time such as separation and thermal polymerization in the manufacturing process, there is a problem that the control is difficult in high temperature thermal polymerization.
Korean Registered Patent No. 0332702 (name of the invention: lacquer coating agent) is obtained by heat-curing urushiol extracted from raw chile to obtain a urushiol oligomer having a molecular weight of 3,000-10,000, and epoxidized to prepare a modified urushiol oligomer by base treatment. A method of preparing a lacquer coating agent by using this alone or by mixing the urushiol oligomer in an appropriate ratio is disclosed.
However, the patent has a problem that the manufacturing process is complicated and time-consuming, the control process for increasing the molecular weight of the urushiol oligomer is difficult.
Korean Patent No. 0344199 (Invention: Epoxy Coating Composition Containing Lacquer Components) includes an anticorrosive epoxy coating composition obtained by mixing an epoxy coating composition composed of an epoxy resin and an amine curing agent with additives such as a lacquer component and a lacquer drying agent. It starts.
However, the patent is to add a lacquer component to a simple epoxy resin, the addition process has to be controlled tightly, and the nature of the epoxy resin has a hassle to add and mix the curing agent before the painting operation. In addition, the epoxy resin is strong alkali resistance but weak acid resistance, its use is limited, there is a problem that the epoxy resin is not different from the existing paints as a main component.

In the process of separating urushiol from lacquer, add an organic solvent to raw lacquer from lacquer, stir well, add water, and stir again. After the mixing and stirring, the mixture is left for a while to separate into two layers, which are separated from the urushiol layer dissolved in the organic solvent and the remaining substances dissolved in water.
When the lacquered layer separated is stored in the freezer, the upper layer does not freeze, but the layer dissolved in water freezes. At this time, the upper layer containing only urushiol can be easily separated. After the mixing and agitation process, the centrifugal separator can be used for faster layer separation.
In addition, the preparation of the inorganic coating is first 5 to 60% by weight of one or more colloidal dispersions selected from colloidal silica, colloidal zirconia or colloidal alumina with a dispersion medium of water or alcohol of pH 2-11; 10 to 70% by weight of one compound selected from alkoxy silanes, silane coupling agents, hydrolysates thereof or subcondensates thereof; 0.1 to 50% by weight of one compound selected from zirconium alkoxide, its hydrolyzate or subcondensate thereof; And 0.1 to 10% by weight of a hydrolysis catalyst and stirred for 3-12 hours at a temperature of 50-80 ° C.
The total solids were adjusted to 5-50% by weight with respect to the mixture obtained after the stirring, and 0.01-5 parts by weight of an additive was added to 100 parts by weight of the total solids of the base resin to apply properties such as applicability, adhesion and drying. Adjust it.
More specifically, the hydrolysis and condensation reaction is carried out by mixing a hydrolysis catalyst to colloidal silica, and alkoxy silane is mixed thereto, and zirconium alkoxide is mixed and stabilized during the reaction to terminate the final reaction to prepare a basic resin. The urushiol of the separated lacquer is mixed. In this case, the base resin may adjust the properties of the inorganic coating composition containing the lacquer as the final composition by mixing the organic solvent and the additive.

In addition, after forming a coating film, a lacquer coating film can be obtained only by a simple heat processing process at the suitable temperature according to the kind of to-be-contained body. Therefore, it is possible to mass-produce lacquer products such as metals, ceramics, plastics, wood, etc. due to a simple coating process and heat treatment process for lacquer, which had problems in mass production.
