Summary
In this study, the production of a paint active agent containing hydroxyapatite (HA) bioceramics isolated from egg shell and carbon graphene aerogel, which prevents noise formation and eliminates thermal problems, and polymeric encapsulated nanoparticle additive that prevents rust formation, can be applied to outer and inner pockets.
It is aimed that this functional paint can be an ideal material candidate for functional use in the building sector.
1. Introduction
Science and technology have become open to innovation and development day by day. Sound insulation is one of the primary desired attractive features due to the increasing urban transformations, the construction of thousands of buildings such as cafes, schools,
houses, discos and bars.
The need to provide insulation has emerged both in the structure of domestic buildings
and in the structure of other types of buildings, elevator rooms, control rooms, machine rooms and the room where many noises are located.
The egg sponge material used for sound insulation in Figure 1 is used in many
organizations today. Egg sponge type sound insulation plays a major role in preventing or minimizing the noise and sound that always occurs in rooms and buildings, both inside and outside.
When sound and noise are too much in an environment, people’s psychological, mental
and physical health may be deteriorated.
For these and similar reasons, the field of insulation is developing day by day and the need for materials with various functional properties has increased for the building sector.
Noise always causes a great negativity on people. For this reason, it is desired to use insulation in both houses and other buildings.

Thermal insulation prevents the temperature in the building environment and the temperatures outside the building to pass with each other. Heat insulation is one of the indispensable and attractive applications in buildings.
In buildings with good thermal insulation, it is possible to protect the hot air in the home environment regardless of the outside temperature. Exterior coatings are not preferred only in the winter season.
Equipment such as ventilators or air conditioners working in the buildings during the summer months provide high electricity consumption when necessary. Parallel to this, heavy bills can force people.
In addition to sound and heat insulation, water repellency and rust prevention in building applications are also desirable conditions. Because with the formation of water, the buildings can get moisture, the insulations can deteriorate and they cannot be used with the desired performance.
In addition, the performance of products used as water repellent may be poor. While the duration of the effect may decrease, the prices are increasing day by day. Rust formation is one of the most important problems in the construction industry.
Rusting is a corrosion condition that occurs when metallic-based products come into contact with water or a liquid. With this corrosion, microcracks in the structural appearance occur with microholes, and over time, excessive brittleness can lead to serious risks that can lead to the breaking of the structure.
In this case, rust removers, which we call antirust, are preferred. However, since these are chemical ingredients, they are not suitable for human inhalation and may cause skin irritation. Their use in paints can show high costs, and their rust formation effect
performance is low.
In this study, the production of active substance- encapsulated polymeric functional
nanoparticles that can be added to paints that can be water-repellent, prevent rust formation, and provide sound and heat insulation in interior and exterior pocket applications against the problems that arise in the construction sector has been carried out
with our air spinning system.
With the addition of active substance, an ideal material candidate that can revolutionize the paint industry will be able to provide added value to the construction industry.

2. Material and Method
2.1. Material
In this study, eggshell wastes were collected from our environment. Carbon graphene aerogel was synthesized in our own laboratory. Sodium alginate (SA) and calcium chloride (CaCl2) as crosslinker were purchased from businesses around us.
2.2. Method
2.2.1. Hydroxyapatite Synthesis from Egg Shell
Eggshells were collected from our environment, sterilized and dried. It was ground into powder in a ceramic mortar. The amount of calcium oxide (CaO) was determined by thermal gravimetric analysis (TGA).
The powder added to the distilled water was precipitated by titration with orthophosphoric acid. The precipitate was filtered and dried in a vacuum oven and left for 1 night. After processing, it was sintered and hydroxyapatite (HA) was produced [1-7].
2.2.2. Obtaining Functional Nanoparticles by Air Spinning
A mixture of sodium alginate (SA), hydroxyapatite (HA) and carbon graphene aerogel (CGA) was provided in distilled water. The calcium chloride (CaCl2) crosslinker was
prepared in distilled water.
Encapsulation process is carried out with core-shell interaction, which can feed into
each other with double nozzles, and nanoparticle is obtained by combining the polymer active substance mixture with air and bringing it together with the crosslinker [1-7]. Figure 2 shows our production of functional nanoparticles with core-shell interaction.

4. Conclusions
In this study, active substance encapsulated functional nanoparticles were economically obtained by air spinning. It will be an ideal material candidate that can be water-repellent, prevent rust formation, can be added to paints for sound and heat insulation, and revolutionize the paint industry in interior and exterior pocket applications.
The different functional properties of this active substance are also known, which can be used in paint and paint applications. The fact that it can be easily obtained from the sources of our country enables the production of this active substance on a more economical scale.
In line with our Vision 2023 targets, we will contribute to the development in the construction sector with our initiative to reduce foreign dependency.
