Abstract
The invention relates to an aqueous antirusting agent applicable to the non-chlorofluorocarbon refrigeration industry. Benzotriazole, benzoic acid and morpholine are first agitated under 50 DEG C to 60 DEG C for three hours; water, monoethanolamine, triethanolamine and 10 percent of ethanol are then weighed in part by weight, sequentially added and agitated to be uniformly mixed according to proportion, the agitation speed is controlled at 100 rotations per minute, the agitation time is controlled at 3 to 5 hours, and thereby the aqueous antirusting agent applicable to the non-chlorofluorocarbon refrigeration industry is obtained. Because the residue rate of the adopted low-residue formula is 10 percent of the residue rate of the traditional formula, the residual amount of the antirusting agent on the surfaces of refrigerating parts is reduced, and thereby the potential hazard of the blockage of the capillary tube of a refrigeration system is prevented. The aqueous antirusting agent does not adopt inorganic salt and fat soap and contain the ingredients of sulfur, phosphorus and chlorine.
Description
Technical field
The present invention relates to water-based antirust agent, be specially a kind of water-based antirust agent that is applicable to floride-free refrigeration industry.
Background technology
The tradition water soluble anti-rust agent adopts composite forming such as inorganic salt, tensio-active agent, rust-inhibiting additive, stablizer, but can cause the obstruction of refrigeration system kapillary, energy consumption height even refrigeration system to scrap if be applied in the words of floride-free refrigeration industry.
Present domestic refrigeration industry is being realized the conversion of fluorin environment protection technology, is badly in need of a kind of component water-based antirust agent that can adapt to new cooling media.
Summary of the invention
The technical problem that the present invention solved is to provide a kind of water-based antirust agent that is applicable to floride-free refrigeration industry, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the present invention solved adopts following technical scheme to realize:
A kind of water-based antirust agent that is applicable to floride-free refrigeration industry comprises the raw material of following weight part:
A kind of water-based antirust agent that is applicable to floride-free refrigeration industry, its preparation method may further comprise the steps:
The first step: earlier benzotriazole, phenylformic acid and morpholine were stirred 3 hours in 50～60 ℃;
Second step: take by weighing water, Monoethanolamine MEA BASF, trolamine, 10% ethanol then by weight; And mix in proportion; Addition sequence is water, Monoethanolamine MEA BASF, trolamine, 10% ethanol; Stirring velocity is controlled at 100 rev/mins, and churning time was controlled at 3-5 hour, promptly obtains a kind of water-based antirust agent that is applicable to floride-free refrigeration industry.
Beneficial effect
Residual rate of the present invention is 10% of a conventional formulation, adopts the low residue prescription, reduces the residual quantity of refrigeration component surface rust-preventive agent, solves the hidden danger that the refrigeration system kapillary stops up.Do not adopt inorganic salt, fatty soap, not sulfur-bearing, phosphorus, chlorine component.
