Abstract
Description
The present invention relates to a liquid curable composition having improved physical properties with improved insulation and exothermic properties and greatly increased strength, bearing capacity, adhesion, and the like.

Complementing this has been developed applications for various manufacturing methods and performance.
However, the practical use of the application of silica airgel in nanomaterials has been made practical because of technical problems that are not differentiated due to lack of dispersion technology, bonding technology, compression technology, etc., compared to existing products for insulation. There was a problem of difficulty.
In addition, the peeling and separation of nanomaterials and other bonding materials is severe, causing a problem of inferior product stability.

In conclusion, the mixture was liquefied by stirring at 1 ~ 550 degrees Celsius and 500 ~ 2,000rpm 1 ~ 30 minutes in the state of mixing nanomaterial and other additive materials, and the liquid was injected into the upper opening such as a silica fiber paper bag. Stitch the openings, lay them horizontally for compression and thickness control, pass through the rollers, and dry and harden them by steam drying, hot air drying, etc. under conditions of 1 to 550 degrees Celsius and 1 to 180 minutes. can do.
As a simple example of the present application and the whole composition and manufacturing method, the cement powder in the general cement manufacturing process is put into a paper bag and sewn into the top opening of the bag. After the application and liquefaction of the additive material, it passes through the roller for compression and thickness control and goes through the drying process.
In the state of mixing nanomaterials with other supporting materials for bearing capacity, crack prevention, compressibility, and reinforcement, it is stirred, infused into a bag (0.1-3mm thickness), sewn, laid horizontally, dried and cured through a roller. It can be easily cut into various forms such as customized length cutting and sheet-shaped flexible roll sheeting method and single plate-shaped board shape according to the application.
The present application can be easily prepared, and it will be readily understood by those skilled in the art. In addition, the key technology is to maximize the solids performance and durability by injecting nanomaterials directly into the bag after liquefaction. In the case of aerogels among nanomaterials, it is recognized that the application complexation with other materials is very difficult due to superhydrophobicity and light weight, and proper material selection and quantity input of nanomaterials and other additive materials are not properly performed. As such, the composition and composition ratio are very important as they remain a constant research topic. The level of liquefaction technology that can be applied like a general paint is desperately needed and the technology such as strength, adhesiveness, bearing capacity, and compressibility must be completed as a whole. Only when the maturity of the technology is mature, there is no cracking and strong supporting paint, and it is possible to make practical and formal products such as sheet-like sheet and plate-shaped board.
Examples of silica airgels in the nanomaterials are that they are sealed in the bag enclosed with the other additive materials, and the other additive materials maintain a firm bonding force, and the sheet manufactured therein is free from peeling and flying due to the bonding member, which is a disadvantage of the existing products. The nanomaterial is preserved completely in the bag, so its performance is maintained as it is, and it is very practical to use, with many advantages such as bendability and water resistance retention without cracking. Powder alone applications may lack the expectation of their properties due to their narrow coverage and self separation and loose pore formation.
Applicant's prior art has reached the present application because the overall physical properties may be poor by the method of immersing the support fibers in the liquid compound and making a solid body and immersion coating, and other conventional techniques are the slurry, solidification after immersion Next, the technology is used to improve durability by fusing the film to the outside of the solid body, but the present application inserts the liquid compound directly into the bag with heat resistance, so that the solid is completed by directly trapping the nano material. There is a big difference in terms of stability, performance and durability.
In addition, it is important that the liquid compounds are properly balanced to realize proper shaping and stable productization of the sheet, and to maximize the differentiation from the existing products in terms of performance. Thermal drying and curing are also combined. Productivity can also be increased.
This liquid curable composition is excellent in supporting capacity, strength, adhesiveness, etc., which maximizes thermal insulation, exothermicity, and conductor formation, which are characteristics of nanomaterials, has a wide range of versatility and application range, greatly increases durability and performance, and does not have peeling and scattering phenomenon. The performance of the material is maintained and the product stability is improved by preventing layer separation and precipitation. It can be applied in various forms to general residential and industrial facilities that require insulation and sound insulation, heat generation, and conductor formation.
Hereinafter, the configuration and operation of the present invention through the preferred embodiments will be described in more detail. It is to be understood, however, that the same is by way of illustration and example only and is not to be construed in a limiting sense. Details that are not described herein will be omitted since those skilled in the art will be able to sufficiently infer technically.

[Test Example] 1. Insulation Evaluation
[Example] 3, [Example] 2, [Example] 1, the heat insulation was increased. The reason for this was determined that the silica airgels with small size formed tightly tight pores with each other and blocked the heat passage as much as possible. In each section, no scattering or cracking of nanomaterials occurred and it was determined that the warpage was good.
EXAMPLES Insulation property was favorable toward 3.2.1, and Comparative example. It was determined that heat insulation is good toward 3.2.1. The reason for this was that the smaller the outer diameter particle size of the silica airgel was, the better the thermal bridge and the air passage were.
[Test Example] 2. Strength Evaluation
[Example] 1, [Example] 2, [Example] 3, the strength was increased. The reason for this was that the larger the outer diameter was, the more the adhesive surface with other materials increased, the higher the strength, and the faster the stirring mixing time was.
[Test Example] 3. When comparing [Example] and {Comparative Example]
Example 1 and Comparative Example 1
Example 2 and Comparative Example 2
Example 3 and Comparative Example 3
In each section, the thermal conductivity remains low as the added amount of silica airgel increases in the 1: 1 comparison between [Example] and [Comparative Example], but the strength, bearing capacity, and binding strength are weak. As the input content increased, the thermal conductivity was kept low, but the strength was weakened. Therefore, it was determined that the application of quantitative application of silica airgel and other additive materials was required to ensure insulation and durability.
In addition, the evaluation of the warpage as a whole, with the nano-material trapped in the bag envelope, there was no flying phenomenon, and the warpage was judged to be good at about 160 degrees. [Comparative Example] 1.2.3 is more flexible than [Example] 1.2.3. This was determined to be relatively good. The reason was determined that the flexibility increased because the content of the solid hardened material was reduced and the hardness was weakened.
[Examples] and [Comparative Examples] In each case, it was determined that the bag was formed in a fibrous form with smooth airflow, so that air permeability was good.
[Test Example] 4. Water repellency evaluation
EXAMPLE The water repellency of 1.2.3 was evaluated to be somewhat lower than the water repellency of 1.2.3. The reason was determined that the higher the content of the silica airgel, the higher the water repellency. Excessive application of silica airgel, however, can lead to the collapse of solids due to the weakening of the overall bearing capacity.
