Description
Technical Field
The invention relates to the technical field of cooling liquid, in particular to a multi-effect low-foam organic radar cooling liquid and application thereof.
Background
A large amount of copper (T2 red copper, HPb59-1 lead brass, etc.), stainless steel (1Cr17Ni2, 1Cr18Ni9Ti, 30 crmnsii 2A, 316, 314, 316L, etc.), cast iron, aluminum alloy (6063, 3a21, 5a05, 2a12, 7075, etc.), and various types of solders are used in liquid cooling systems of military radars, warning aircraft, ship-borne radars, airborne radars, special air conditioners, electronic devices, etc. Besides the variety of metal materials, the variety of non-metal materials is also many, for example: nitrile rubbers (5171, 5870, 5470, 5080, etc.), ethylene propylene diene monomer rubbers, silicone rubbers, fluororubbers, fluorosilicone rubbers, and various non-metallic materials such as sealants, sealing rings, etc. The common cooling liquid for the vehicle can not realize the anti-corrosion protection of various metal materials and the good adaptability with various non-metal materials. Liquid cooling systems of radars, electronic equipment and the like cannot be directly added into the anti-freezing liquid for vehicles, and special cooling liquid required by radars and electronic equipment is required to be used.
At present, the cooling liquid used by radar equipment in China mainly comprises cooling liquid No. 40 and 65 meeting YQB/KJ30-1998 specifications and cooling liquid No. AF40 and AF65 meeting GJB 6100-. The other type of cooling liquid is more applied to radar and is No. 60 cooling liquid, and the implementation is the enterprise standard.
The currently used No. 40 and No. 65 cooling liquids are inorganic cooling liquids, and have high corrosivity on metals, particularly on aluminum alloys and solders. The conventional organic type AF40 cooling liquid and AF65 cooling liquid are easy to generate bubbles when in use, so that heat dissipation is influenced, and cavitation corrosion is accelerated. Other available organic type No. 65 cooling liquid can make aluminum alloy become black by corrosion in a short time.
No. 60 cooling liquid used by the existing radar is mainly inorganic cooling liquid, and some existing No. 60 cooling liquids use sodium silicate additives, so that after the cooling liquid is used for a period of time, sediments and scales are easily generated to block liquid cooling pipelines, and the cooling liquid has high corrosion to equipment. And the existing other No. 60 cooling liquids have poor adaptability to non-metal materials and are easy to leak.
Because both inorganic type and organic type cooling liquid used for radar have some problems, it is imperative to develop a cooling liquid for radar which can realize multiple-effect protection for metal and non-metal materials and has low foaming property.

the cooling liquid of the invention is based on 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 composite corrosion inhibitor and utilizing the synergistic effect of the organic corrosion inhibitors.

The preparation method of the multiple-effect and low-foam organic radar cooling liquid comprises the following steps:

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 ℃ to 65 ℃ below zero, the corrosion inhibition effect on various metals such as aluminum alloy, stainless steel, copper (alloy), cast iron, carbon steel and the like and corresponding solders is good, the adaptability with non-metal materials such as nitrile rubber, fluororubber, silicon rubber, sealant and the like is good, and liquid leakage cannot occur during use. The aluminum alloy can not be blackened, and the original metal color and luster of the aluminum alloy can be kept after the aluminum alloy is used.
3. The radar cooling liquid solves the problem that other organic cooling liquids have large foam or are easy to corrode aluminum alloy and turn black, and has low foam tendency and strong corrosion inhibition performance. The cooling liquid has long service life which is more than 3 times of that of the traditional inorganic cooling liquid, and does not generate precipitates in use.
