Description
Technical field
The present invention relates to being related to a kind of heat-conducting system to seal protective agent up for safekeeping, especially taken for engine-cooling system, boiler
The heat-exchange systems such as heating system.
Background technique
Boiler thermodynamic system, engine-cooling system and other industrial equipments and pipeline are mainly steel systeming equipment, are being deactivated
Period, if do not taken safeguard measure or safeguard measure improper, metallic interior surface will cause the corrosion of dissolved oxygen, corrosion rate
It is general more much faster than during operation.The heat power equipments such as the boiler by heavy corrosion, majority are to occur during deactivating and running
Period develops again caused by.Because outside air will largely enter water-steam system after equipment out of use, though system has been put
Water, but metallic interior surface is always at dampness, and the oxygen in air is dissolved in its surface, is even up to saturated, it is easy to draw
Play dissolved oxygen corrosion.If have the salt crust that can be dissolved in water on heat power equipment metal surface, corrosion will be more serious.Thermally conductive system
Not to the utmost, the oxygen in outside air also can be soluble in water, dissolves metal by the position row that water is not discharged or had after deactivating by system
Oxygen corrosion.The dewatered mixture of heat-conducting system metallic interior surface during deactivating.Since these products are than more loose, do not have to metal
It is protective, once corrosion will continue to go on.No matter the corrosion occurred during deactivating corrosion product or corrodes
The defect caused by metal surface can all cause running corrosion after equipment starting.Therefore, during heat-conducting system deactivates
Using safeguard measure appropriate, corrode to equipment is effectively slowed down, it is ensured that safe operation, extending service life of equipment has important meaning
Justice
Corrode Basic Mechanism according to Laying-up Protection of Thermal System, causing the basic external condition of corrosion is moisture, dissolved oxygen and pH
Value forms passivating film in metal surface before equipment out of use using corrosion inhibiter, and it is most effective for preventing the occurrence and development of corrosion
Means.
Summary of the invention
It is an object of the invention to provide one kind can be in heat-exchange systems lay-off periods such as engine-cooling system, boiler heating systems
Between digital preservation system inner surface metal seal protective agent up for safekeeping.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of heat-conducting system seals protective agent up for safekeeping, the raw material including following parts by weight:

The present invention also provides above-mentioned heat-conducting systems to seal protectant preparation method up for safekeeping, includes the following steps:
(1) 3- TSL 8330 and sodium hydroxide are dissolved in deionized water according to the ratio, are protected in 70-90 DEG C
Warm water solution 2h removes methanol by vacuum distillation；
(2) glycerol stirring (or so general half an hour) is added；
(3) 1- phenyl -5- mercapto tetrazole, N- cyclohexyl taurine are added according to the ratio, are stirred evenly.
All raw materials of the present invention are commercially available to be bought.
The invention also includes above-mentioned heat-conducting systems to seal protective agent up for safekeeping for preventing the application of metal erosion etc..
Heat-conducting system of the present invention, which seals protective agent up for safekeeping, can be directly applied to metal surface, such as is directly injected into industry and sets
In standby or pipeline；It is applied to metal surface again after can also mixing with appropriate solvent (such as water).
Further, the metal includes red copper, brass, steel, cast iron, scolding tin, cast aluminium etc..
Heat-conducting system of the present invention seals protective agent up for safekeeping, in which: 3- TSL 8330 is the inhibition of organosilicon anti-corrosion
Agent, metallic interior surface can form gelatinous complex protective film, prevent the infiltration of oxygen, 1- phenyl -5- mercapto tetrazole and
N- cyclohexyl taurine compounding has synergistic effect to non-ferrous metal inhibition, and effective use synergistic effect can be achieved with less inhibition object
Matter Fu obtains preferable protecting effect, can reduce the time in this way and reduce cost, improve benefit；The good inhibition scolding tin of long-time,
The corrosion of aluminium parts；The passivating film that the 1- phenyl -5- mercapto tetrazole of several ppm is formed can be used to inhibit table in heat-conducting system
The gaseous corrosion of copper and aluminium parts in face.
Test result shows: protectant glass corrosion test result of sealing up for safekeeping of the invention reaches and is higher than SH/T0521 mark
Standard, the rust prevention test of alternating hot and cold liquid phase is it can be said that bright product of the present invention can be can have to various well under hot conditions
Non-ferrous metal carries out macrocyclic protection.
