Description
Technical Field
The invention relates to the technical field of cooling liquid for phased array radar, in particular to low-conductivity dielectric cooling liquid for glycol type phased array radar and application thereof.
Background
Electronic equipment liquid cooling systems such as military phased array radars, early warning aircraft, carrier-borne radars and airborne radars use a large amount of various metal materials such as copper (T2 red copper, HPb59-1 lead brass and the like), stainless steel (304, 316L and the like), aluminum alloy (6063, 3A21, 5A05 and the like) and different types of welding materials used for metal welding. Besides the variety of metal materials, the variety of non-metal materials is also many, for example: nitrile rubbers (5171, 5870, etc.), O-rings (ethylene propylene diene monomer, fluorosilicone rubber), silicone rubber, fluororubber, etc. The traditional cooling liquid for the radar can protect the materials, but has conductivity, and the protection of the phased array radar electronic components after the cooling liquid is accidentally leaked cannot be realized.
At present, the cooling liquid used by radar equipment in China mainly comprises 65 # cooling liquid meeting YQB/KJ30-1998 specifications and AF65 # cooling liquid meeting GJB 6100 and 2007 specifications. And various enterprise standard No. 60 coolants.
The current No. 60 and No. 65 radar cooling liquids have high conductivity, and are easy to cause short circuit and burnout of electronic components of radar electronic equipment after accidental leakage, so that the equipment cannot be used.
Because the No. 60 and No. 65 radar cooling liquids used by the radar have higher conductivity, the development of the glycol type dielectric cooling liquid which can realize multiple-effect protection on a phased array radar liquid cooling system and has low conductivity is imperative.
Disclosure of Invention
In order to solve the defects of the cooling liquid for No. 60 and No. 65 radars in the prior art, the invention provides the low-conductivity dielectric cooling liquid for the glycol type phased array radar and the application thereof.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the low-conductivity dielectric cooling liquid for the ethylene glycol type phased array radar is prepared from the following raw materials in parts by weight:
the cooling liquid of the invention is based on ethylene glycol and deionized water, the addition amount of the corrosion inhibitor is reasonably controlled, and the corrosion inhibition effect of the corrosion inhibitor is improved by adopting a compounding method, using the organic non-ionic composite corrosion inhibitor and utilizing the synergistic effect of the organic corrosion inhibitors. The corrosion inhibitor not only effectively enhances the corrosion resistance, but also controls the concentration of the corrosion inhibitor in a lower range, so that the influence of the corrosion inhibitor on the freezing point is minimum. The invention effectively utilizes the synergistic effect of the organic corrosion inhibitors and can realize better protection effect with less corrosion inhibiting substances. Therefore, the cost can be greatly reduced, and the economic benefit is improved.
In the invention, the organic non-ionic composite corrosion inhibitor is preferably a combination of two or more of pimelic acid, isooctanoic acid, sebacic acid, benzoic acid, p-tert-butylbenzoic acid, benzotriazole, cinnamic acid, organic alkali and imidazole.
Further, the organic non-ionic composite corrosion inhibitor is one of the following combination modes:
(1) an organic non-ionic composite corrosion inhibitor consisting of benzoic acid, sebacic acid, isooctanoic acid, imidazole, cinnamic acid and organic alkali;
(2) an organic non-ionic composite corrosion inhibitor consisting of p-tert-butylbenzoic acid, sebacic acid, benzotriazole, imidazole, organic alkali and cinnamic acid;
(3) an organic non-ionic composite corrosion inhibitor composed of p-tert-butylbenzoic acid, sebacic acid, benzotriazole, imidazole, organic base and pimelic acid.
The organic non-ionic corrosion inhibitor in the combination modes has good synergistic effect, so that the protection effect is effectively enhanced.
Further, the low-conductivity dielectric cooling liquid for the phased array radar is prepared from the following raw materials in parts by weight:
further, the low-conductivity dielectric cooling liquid for the phased array radar is prepared from the following raw materials in parts by weight:
further, the rubber protective agent is one or two of mercaptobenzotriazole and dextrin.
Further, the scale inhibitor is polyacrylic acid; the defoaming agent is a high-molecular polyether defoaming agent. Various high molecular polyether defoaming agents commonly used in the art are suitable for the cooling liquid in the present invention, but in order to achieve better effects on the low foaming performance of the cooling liquid, the present invention further prefers the defoaming agent to be polyoxyethylene polyoxypropylene ether having a molecular weight of 1900-2200, which is a compound ring-opening polymerized from an initiator (an active hydrogen group-containing compound) in the presence of ethylene oxide, propylene oxide and a catalyst.
The preparation method of the low-conductivity dielectric cooling liquid for the phased array radar comprises the following steps:
stirring the organic non-ionic compound corrosion inhibitor, the organic non-ionic rubber protective agent, the scale inhibitor and the defoaming agent according to the formula ratio under the heating condition to fully dissolve all the components into base liquid consisting of ethylene glycol and deionized water, and then stirring, standing, filtering by an ion exchange column and finely filtering by a filter membrane to obtain the cooling liquid.
The invention has the beneficial effects that:
1. the cooling liquid of the invention is based on glycol and deionized water, and realizes corrosion protection of multi-metal materials and solder in liquid cooling systems such as radar and the like by adding the organic non-ionic composite corrosion inhibitor, and the corrosion inhibitor protective film has good stability. The shrinkage and swelling of the cooling liquid to the rubber material are inhibited by adding the organic non-ionic rubber protective agent, and precipitation and scaling can be prevented by adding the scale inhibitor; in addition, the small amount of the defoaming agent is added to inhibit and eliminate the cooling liquid foam, and when the defoaming agent is polyoxyethylene polyoxypropylene ether with the molecular weight of 1900-2200, the defoaming effect is excellent. The components of the cooling liquid are reasonable in proportion, and the prepared cooling liquid is high in comprehensive performance.
2. The formula of the cooling liquid is organic, the application range is wide, the cooling liquid can be used in the environment of 112-65 ℃, has good corrosion inhibition effect on various metals such as aluminum alloy, stainless steel, copper (alloy), cast iron, carbon steel and the like and corresponding solders, and has good adaptability with non-metal materials such as nitrile rubber, fluororubber, silicon rubber, O-shaped rings (ethylene propylene diene monomer, fluorosilicone rubber) and the like.
3. The radar cooling liquid solves the problem of high conductivity of other radar cooling liquids. The conductivity of the cooling liquid of the invention is less than 5 mu s/cm2Leakage hazard degree: the power-on time is more than 200h, and the circuit has no short circuit and corrosion phenomena.
4. The low-conductivity dielectric cooling liquid for the phased array radar with the brand numbers of 60 and 65, which is prepared by the invention, has a very good application effect in liquid cooling systems of military radars, early warning planes, airborne radars, ship-borne radars, civil meteorological radars, electronic equipment and the like.
