Description

Sterilizing paint for vehicle {Sterilizing paint for vehicle}

The present invention relates to a vehicle disinfectant paint, and more particularly, to a surface of a vehicle component installed inside a vehicle by applying a disinfectant paint formed by mixing oil or water paint and sterilization components in a constant ratio to form a sterilization coating film. The present invention relates to a vehicle antiseptic paint capable of providing a pleasant hygienic environment to a driver by removing harmful components and bacteria.

Recently, with the improvement of quality of life and the impact on well-being, interest in environmental hygiene is increasing not only for construction and electronic products but also for vehicles. In particular, volatile organic compounds (VOC) regulation and sick house syndrome are examples of health hygiene. In addition, in the automobile industry, in line with market changes, interests in quality level, design development, and emotional quality that meet consumer's preferences are increasing, while interior materials having functional characteristics such as antifouling, chemical resistance, and eco-friendliness are being developed. .

We are exposed to germs and microorganisms that are harmful to the human body, such as E. coli, in our daily lives, and the damage is frequent. As the perception that the damage caused by microorganisms is not safe for fiber, wood, glass as well as plastic has been spreading, various plastic products with antibacterial function have been developed as consumer's desire for hygiene products gradually increases.

In general, the antibacterial action is to inhibit the growth of microorganisms, and means to suppress or prevent the growth of microorganisms. However, the antimicrobial activity has a short duration and its effect is insignificant. Sterilization, on the other hand, means killing or eliminating microorganisms into a sterile state, the duration of which ranges from 1.5 to 5 years, and also has excellent antiseptic effect including antibacterial activity.

Common types of microorganisms include bacteria, fungi, viruses, and yeasts. Among them, microorganisms that can penetrate plastic products and cause problems are mainly known as bacteria and fungi, and the antimicrobial action of most plastic products seeks a method for suppressing reproduction of these two microorganisms. In the method of breeding these microorganisms, when a contaminant adheres to the surface of the product in which the bacteria are present, the microorganisms multiply by using the contaminant as nutrients. Environmental conditions for breeding microorganisms include temperature and humidity, and under certain conditions, microorganisms reproduce very rapidly. Among them, the most influential factor is temperature, which shows the best fertility at about 37 ° C, similar to human body temperature.

Therefore, it can be said that the influence is serious in the place where a lot of people touch. Therefore, the propagation of these microorganisms is likely to occur in areas where there is much contact with human hands. In order to prevent the harmful effects of microorganisms, fungicides such as hydrogen peroxide, chlorine dioxide and calcium ions have been used to remove or suppress the microorganisms on the surface of the product. However, their effect is excellent, but it is harmful to the human body, and has the disadvantage of not showing a lasting effect was limited in its use.

Currently, many sterilizing materials are commercialized and sold, but most of them are used in the form of dispersing or dispersing the antimicrobial in the form of a liquid, which is difficult to use for a long time because it is washed or gradually removed during use. Therefore, in order to overcome these disadvantages, development of a polymer material that is easy to use and convenient to use has been actively progressed.

In order to meet the above requirements, research on antimicrobial polymers that exhibit high antimicrobial properties by incorporating functional groups having excellent sterilization (sterilization, disinfection) directly into the polymer chains is also being conducted.

In particular, in the vehicle interior manufacturing process, the volatile organic solvent compound (hereinafter referred to as "VOC") generated during painting has a harmful effect on the human body not only during painting but also during use, thereby reducing VOC in the use of paint. Many techniques have been studied and applied. In addition, oil paints that have been used to reduce VOCs are changing to water-soluble paints due to problems of VOC and environmental pollution during painting.

In addition, since interest in environmentally friendly and hygienic materials has recently increased, there is a need for technical development of hygienic disinfectant paints that can be extracted from nature and are eco-friendly and disinfectant.

An object of the present invention for solving the above problems is to apply a sterilizing paint which is a mixture of oily or water-based paints and sterilizing ingredients in a certain ratio on one surface of the vehicle parts installed in the vehicle to form a sterilizing coating film inside the vehicle It is to provide a vehicle disinfectant paint that can remove a harmful component and bacteria to provide a comfortable hygiene environment to the driver.

The vehicle antiseptic paint according to the present invention for solving the above problems is a vehicle antiseptic paint applied to a vehicle component, the vehicle antiseptic paint, the paint is prepared by mixing a pigment and a colorant; And a sterilizing component encapsulated by an inorganic material and mixed with the paint at a constant ratio, and spraying on one surface of the vehicle component to form a sterilizing coating film.
In addition, the paint is 90 ~ 99.5 wt%, the sterilization component is preferably 0.5 to 10 wt%.
In addition, the paint is preferably a hot air drying type or a one-component and two-component type oil paint for UV curing, which is mainly composed of urethane and acrylic using an organic solvent.
In addition, the paint is preferably a hot air-drying water-based paint, the main component of acrylic (Acrylic) and melamine (Melamine) using water as a solvent.
In addition, the sterilizing component is preferably a bactericidal Alexin natural sterilization component.
In addition, the vehicle sterilizing paint is preferably exposed to air to sterilize 99.99% of the bacteria present in the vehicle parts.
In addition, the vehicle antiseptic paint prevents the growth and habitat of microorganisms, kills or removes microorganisms to make it aseptic, and the duration of the aseptic state is preferably 1.5 to 5 years.
