DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an infrared low emissivity coating, and more particularly to a binder composition thereof. [Prior Art] • The consumption of this source has increased dramatically. “Energy saving is the consensus of the whole world. In the industry, thermal insulation coatings are of great significance at this moment. The heat of protection is mainly to block the heat loss of the boiler tubes themselves. On the other hand, the ί and the 起 are used to protect the 蒦. The heat source will generally increase the specific gravity of the infrared light when the convection, light radiation, and conduction are transmitted. The light heat is very important. There are three ways to reduce the infrared light shot: -, change the infrared radiation characteristics of the target, that is, the emissivity distribution of the target, two = =,;, adjust the infrared _ broadcast road #. Develop low-level radiation; degree and reduce infrared/day as an early effective insulation method. Burning systems or high-temperature objects will emit a large amount of radiation. The heat generated by the equipment will be absorbed by the equipment and the water pipe group. The suction, ..., and light radiation will re-radiate. Therefore, the technology reduces the loss and saving of the industrial steel furnace. Fuel, medium carbon steel that protects high surface temperature: Spraying low emissivity coatings to reduce heat loss to reduce the amount of materials used to reduce c〇2 gas production and system energy saving: low emissivity Paint development originated from military infrared stealth applications. From the earliest, in 1967, the US Air Force commissioned Honeywell (H〇neywel) to conduct research on diffuse reflective infrared reflective coatings. In the second paragraph of 201018714, from the late 1970s to the mid-1980s, the US Army Armaments Command conducted many studies on medium and far-infrared stealth coatings and suitable adhesives. The Nntick Research and Development Laboratory and the Beivoir Research and Development Center are also low. Emissivity heat stealth coatings do a lot of research work. After the mid-1980s, the Western countries have been involved in hot stealth coating research. German, English, French, German, Canadian and Australian have all reported information on this aspect of work during this period. A report on the development of thermal stealth coatings published by the Australian Department of Defense Materials Laboratory in 1984 attracted widespread attention. According to experts' speculation, the development of the thermal hidden scent paint has entered the active secret development stage from the initial exploration. The first stage of emissivity is higher than 0.5, and the second generation of infrared in the third stage. The line stealth coating 'is mainly strengthened in the development of new binders and pigments. The fourth stage is due to the maturity stage of the second generation of infrared stealth coatings. The coatings are made of polymers with high infrared transparency (possibly butyl rubber, Krat〇n resin) and coloring pigments (possibly including cadmium sulfide, iron oxide, etc.). A small amount of metallic pigments 'this coating has been commercialized, and commercial products have an emissivity of less than 〇.5. Aestra is one of the manufacturers in the United States, and the No. 5 formula in Table 1 is its prototype.

The product of the physical vapor deposition method has an emissivity of up to 0.3'. The disadvantages of the physical vapor deposition method are high and the coating on the spot is difficult, and the properties of the functional group and the infrared light transmittance of the binder are rarely further discussed. Only US3189576 mentions the use of silicon-bonded oxime resin as a binder, and US4131593 ® for nuclear flash protection. Now the raw material is high in enamel resin (special type enamel resin > NT$ l〇) 〇〇/kg), because the emissivity of the resin is not low, it is necessary to add a high proportion of metal paste to reduce the emissivity, and the price of the aluminum paste is also not to lose the resin, so the price of the coating is very high. And the emissivity can only reach 0.45 or above. Table 2 Low emissivity coating patent efficacy

In the domestic situation, the research history of infrared low emissivity coatings is very short, and it is limited to military research units. Because this technology involves the defense stealth stealth technology (including missiles, stealth fighters, aircraft, ground equipment, fans® color clothing), advanced countries are extremely confidential, so the research and development situation is less disclosed, compared with the rapid development of foreign countries. Infrared stealth technology, there is still a considerable gap in China. Although it does not develop national defense military, it is very important to save energy in Minsheng. However, there are not many such products in China, the color is only gray, the infrared emissivity is higher than 0.5, and it is less used in industrial energy conservation. Tsinghua University has discussed the application of nano-sized silver particles and inorganic binders on films. The infrared emissivity is about 0.04. In addition, the transparency of double-layer polymer matrix is also affected by low emissivity. The infrared emissivity is higher than 0.7. Domestic schools discuss the development of conductive polymer materials. Although there are some scattered research and development in the academic world, they are not too expensive and have poor physical properties. Therefore, the emissivity is too high and it is difficult to obtain industrial energy-saving applications. In summary, there is still a long way to go in China for the practical use of infrared low emissivity coatings, energy saving, environmental protection, and colorization. SUMMARY OF THE INVENTION The present invention provides a method for forming an infrared low emissivity paint comprising 10 to 30 parts by weight of a multicomponent copolymer, 70 to 90 parts by weight of a double bond monomer and an acrylate, and 0.1 to 0.3 parts by weight. The initiator is dissolved in 100 8 .201018714 to 150 parts by weight of a solvent, and then heated to graft the double bond monomer and the acrylate to the multicomponent copolymer to form a binder; and 100 parts by weight of the binder, 10 to 30 parts by weight of the metal filler, 0.1 to 1 part by weight of the colored filler, 5 to 10 parts by weight of the semiconductor filler, and 0.5 to 1 part by weight of the auxiliary agent are uniformly mixed to form an infrared low emissivity filler. The present invention also provides an infrared low emissivity coating comprising a binder comprising 10 to 30 parts by weight of a multicomponent copolymer and 70 to 90 parts by weight of a double bond monomer and an acrylate graft copolymerized; and 10 to 30 The weight of the metal filler, 0.1 to 1 part by weight of the colored filler, 5 to 10 parts by weight of the semiconductor filler, 0.5 to 1 part by weight of the auxiliary agent and 100 parts by weight of the binder are uniformly mixed. [Embodiment] The binder is the main film-forming substance of the coating, and is one of the main factors mainly affecting the emissivity of the coating. At least 60% of the absorption capacity of the thermal infrared band of the coating depends on the binder. At present, more research is on pigments and fillers, while binders are less inked, and it is difficult to obtain effective material information because of the principle of non-disclosure of military applications. In addition, in addition to the general requirements of physical and mechanical properties, construction performance, and low cost, the binder should also have low infrared emissivity or high transparency. Generally used for coating binder resin, the transparency is low and the emissivity is high in the wavelength of 8~14μηη. Even the excellent infrared transparent Kraton resin has an average emissivity of 0.84 in the far infrared band. Accordingly, the present invention proposes a low emissivity binder to overcome the high emissivity of the coating. In this case, it is proposed to replace the special type enamel resin with a lower-cost, lower emissivity binder, which is not only cheap, high temperature resistant, and the emissivity can be less than 0.2, which makes the low emissivity coating 9.201018714 successful In the past, it was only possible to produce low emissivity products using the more expensive physical vapor deposition (under vacuum), so it is possible to achieve a large area in the future, especially for automotive and architectural applications. First, the initiator is dissolved in a solvent and heated to form a radical. Suitable starters for use in the present invention are thermal starters such as azo or peroxides. Azos such as 2,2'-azobis(2,4-dimethyl valeronitrile), dimercapto, 2,2' - azo 2,2'-azobis(2-methylpropionate), 2,2-azobisisobutyronitrile (hereinafter referred to as AIBN), 2,2 -2,2-azobis(2-methylisobutyronitrile), 1,1'-azobis(cyclohexane-1-carbonitrile) 1,1'-chaotic 2 〇1^3(.}^1〇116Father&1^-1-〇&!'1)〇11!1;1' by)), 2,2'-azo double [N-2- Propyl-2-mercaptopropionamide] (2,2'-azobis[N-(2-propenyl)_2_methylpropionamide]), 1·[(cyano-1-methylethyl)-azo]曱Indole (l-[(cyano-l-methylethyl)azo]formamide), 2,2'-azobis(Ν-butyl-2-methylpropanol) (2,2'-azobis(N- Butyl-2_methylpropionamide)), 2,2' azobis(N-cyclohexyl-2-mercaptopropenamine) (2,2'42〇1^(]^-〇}^1〇]16))^ 1-2-11161; 11}^1' (^ dish 11^46), or other suitable azo initiators; peroxides include benzoyl peroxide (benzo Yl peroxide), 1,1-bis(tert-butylperoxycyclohexane), 2,5-bis (t-butylper 10 201018714 oxy )-2,5-bis(tert-butylperoxy-2,5-dimethylcyclohexane), 2,5-bis(t-butylperoxy)-2,5- Dimethyl 3-cyclohexyne (2,5-bis(tert-butylperoxy-2,5-dimethyl-3-cyclohexyne) 'bis(1-(t-butylperoxy)-1-fluorenyl) Bis(butyl-butylperoxy-l-methy-ethyl)benzene, tert-butyl hydroperoxide, tert-butyl peroxide ), tert-butyl peroxybenzoate, cumene hydroperoxide, cyclohexanone peroxide, dicumyl peroxide ), lauroyl peroxide, or other suitable peroxide. The above thermal initiators may be used in combination or in combination, as needed.

Suitable solvents may be dimethyl benzene, benzene, tetrahydrofuran, n-butanol, urethane. In the subsequent polymerization, the action of the solvent includes dissolving and dispersing the reactants, promoting uniform contact of the reactants, controlling temperature, transferring heat, promoting bond transfer, and controlling molecular weight. Next, the multicomponent copolymer, the double bond monomer, and the acrylate are dissolved in the above radical-containing solution, and then heated to graft the double bond monomer and the acrylate to the polyfluorene copolymer to form a binder. The double bond monomer may be styrene, polybutadiene, ethylene, propylene, acrylonitrile, or a combination thereof.
