These properties are being applied as high-tech materials for sealants, gaskets, rubber molding, and heat dissipation.

In the present invention, in the silicon compound, the radical of the peroxide reacts with the silicon to take hydrogen from the silicon to stabilize the peroxide, activate the silicon, and the activated silicon causes a chain reaction to form a stabilized silicon network. In this way, the stabilized silicon network serves as a barrier between the heat sources to block heat supplied from the secondary heat source and prevent the inflow of oxygen.

The peroxide may be used to improve crosslinking properties. For example, the peroxide may include dicumyl peroxide (DCP), 1,1-di-(tert-butylperoxy)-3,3, 5-trimethylcyclohexane [1,1-di-(tert-butylperoxy)-3,3,5-trimethylcyclohexane], di-(2-tert-buty-peroxyisopropyl)-benzene [di-(2-tert -buty-peroxyisopropyl)-benzene], butyl-4,4-bis(tert-butyldioxy) valerate [Butyl 4,4-bis(tert-butyldioxy) valerate], di-(2,4-dichlorobenzoyl) -peroxide [Di-(2,4-dichlorobenzoyl)-peroxi de], di-(2,4-dichlorobenzoyl)-peroxide [Di-(2,4-dichlorobenzoyl)-peroxide], dibenzoyl peroxide ( Dibenzoyl peroxide], tert-Butyl peroxybenzoate, tert-Butylcumylperoxide, 2,5-dimethyl-2,5-di-(tert-butylperoxy)- Hexane [2,5-Dimethyl-2,5-di-(tert-butylperoxy)-hexane], Di-tert-butylperoxide and 2,5-dimethyl-2,5-di( At least one selected from the group consisting of tert-butylperoxy)hexyme-3 [2,5-dimethyl-2,5-di(tertbutylperoxy)hexyme-3] may be used.

The flame retardant satisfies Restriction of Hazardous Substances (RoHS), and brominated flame retardants may be used as the flame retardant. In general, halogen flame retardants compete with oxygen for radicals generated in a combustion process, and halogenated radicals are chained. It does not propagate the reaction, so the fire goes out.

Specifically, active radicals OH and active radicals H, which play a role in driving combustion, are trapped and stabilized by HX, and HX is non-flammable and has a dilution effect and an oxygen blocking effect, so flame retardancy is exhibited.

Among halogens, iodine is the most effective flame retardant element, but is expensive and lacks heat resistance and light resistance.

In contrast, bromine is the second most effective flame retardant element after iodine and is most widely used because it can produce a high flame retardant effect in a small amount that does not affect the physical properties of the polymer. In particular, the phenomenon that only traces of carbonization are visible after digestion is a distinctive feature from existing flame retardants.

For example, in the present invention, the brominated flame retardant includes tetrabromobisphenol-A (tetrabromobisphenol-A TBBA, TBBPA), tetrabromobisphenol-A ether, 1,2-bis (tribro 1,2-bis(tribromophenoxy)ethane, 2,4,6-tribromophenyl glycidyl ether, tetrabromophthalic anhydride (tetrabromophthalic anhydride), dimethyl 4-bromophthalate, tetrabromo phthalic disodium, decabromodiphenyl ether, decabromodiphenyl oxide , DBDPO), decabromodiphenyl ethane (DBDPE), 1,4-bis (pentabromophenoxy) tetrabromobenzene (1,4-bis (pentabromophenoxy) tetrabromobenzene), tribromophenoxyethane (tribromophenoxy ethane), 1,2-bis(pentabromophenyl)ethane, bromo trimethylphenyl indane, pentabromobenzyl acrylate At least one selected from the group consisting of pentabromodiphenyl benzyl bromide and hexabromobenzene may be used, and preferably the brominated flame retardant is decabromodiphenyl ethane, DBDPE) may be used.

The flame retardant adjuvant consists of flame retardant compounds such as antimony trioxide and antimony pentoxide, metal antimony and antimony trichloride such as sodium antimonate, aluminum hydroxide, magnesium hydroxide, zinc borate, zinc stannate, molybdate, zirconium, and mixtures thereof. It may be selected from the group, preferably, antimony trioxide may be used as the flame retardant adjuvant.

The antimony compound itself has extremely limited flame retardancy, but when combined with a halogenated flame retardant, it exhibits a synergism effect that greatly increases the radical trapping effect.

Typically, the antimony trioxide reacts with halogen to generate SbOCl and SbCl ₃ , SbCl generates HCl to exhibit a radical trapping effect, SbCl ₃ is also a heavy gas and exhibits an oxygen shielding effect, and SbOCl exhibits a dehydrocarbonization action. do.

The Ge-lite is called pozzolan, and contains about 2.0 ppm of germanium and contains a large amount of far-infrared rays and anions, and representative examples include volcanic ash, silicate clay, and silicate.

The cypress tree (Chamaecyparis obtusa) is also called a cypress tree, and is an evergreen tree of the gymnosperm plant Coniferous Arborvitaceae, native to Japan, but developed in the southern region of Korea. It is widely cultivated as a plantation species, and is used as a deodorant and antibacterial agent due to the unique scent of cypress trees.

Phytoncide produced in cypress trees is a self-defense substance of plants, and is a substance emitted or secreted by plants to resist pathogens, pests, molds, etc., and contains sterilization and insecticidal components in itself. The constituents of phytoncide are organic compounds composed of terpenes, phenolic compounds, alkaloids, glycosides, etc., and are known to have antibacterial, sedative, deodorizing, and stress relieving effects. These phytoncides are natural substances, not chemically synthesized substances, are easily absorbed by the human body, and selectively sterilize bacteria harmful to humans.

In addition, phytoncide is known to have numerous functions such as antibacterial action, deodorization action, sedation action and stress relief action, and it cleans and moisturizes the skin with excellent sterilization, antibacterial and cleansing action, and strengthens the body's immune function.

A research result has been reported that the concentration of cortisol, a stress hormone, is remarkably reduced when inhaling phytoncide, and it is known that phytoncide does not generate a bad odor even when animal carcasses rot in the forest. In addition, it calms the central nervous system to give a pleasant feeling, extends sleep time, and helps to get a good night's sleep.

In addition, it has been found to be effective in hyperlipidemia and thrombotic heart failure by improving the blood circulation system, and it is also known for its strong antibacterial action that does not create resistance in the human body. Phytoncide, a natural substance, is known to be the most effective in preventing allergies with no side effects by repelling up to 90% of house dust mites.

The cypress tree extract may be prepared using various known extraction methods. For example, the cypress tree extract may be extracted using various extraction methods such as hot water extraction, organic solvent extraction, ultrasonic extraction, and supercritical extraction. In the present invention, the configuration of preparing a cypress tree extract using the cypress tree is a known technique in the art, and a detailed description thereof will be omitted for convenience of description and clarity of the technical idea of the present invention.
