Abstract
The present invention discloses main components of corrosion-proof paint in a radiator made of steel or aluminum, and a preparing method thereof. In the paint, modified epoxy resin is compounded from epoxy resin, phenolic resin and acrylic resin (or silicon oil); titanium white powder, kaoline, soft black (or iron red), etc. are used as pigment and filler; solvents of alcohols and ketones are used as diluting agents; gas-phase silicon dioxide, organic bentonite, polyether modified silicon oil, etc. are used as auxiliary agents; the modified epoxy resin, the pigment and filler, the diluting agents and the auxiliary agents are mixed to prepare the corrosion-proof paint with good performance in a radiator. The paint is coated on the internal surface of a phosphorized radiator made of steel or aluminum so that a coating film can resist the corrosion of alkaline water (pH value is more than 12) at 140 DEG C, and the adhesive force and the resistance to high-temperature dynamic loop water impact corrosion are high. The service life of the radiator made of steel or aluminium can be guaranteed.
Description
Technical field
The present invention relates to a kind of protective system and preparation method thereof, dual-purpose nonpoisonous and tasteless scatterer inner side anticorrosion coating of particularly a kind of high performance and long service life steel aluminium and preparation method thereof.
Background technology
The common issue with that steel or Aluminium Radiator face is interior anticorrosion, promptly how to prevent the corrosion of the feedwater of High Temperature High Pressure to radiator inwall, thereby solves the long lifetime of scatterer and the problem of safe operation.
With regard to the anticorrosion problem of scatterer, people have invented the whole bag of tricks and have solved it.Comprise electro-galvanizing, nickel plating, chemical plating nickel-phosphorus alloy, coating protection, electrochemical cathodic protection and add inhibiter etc., but implement that various shortcomings are arranged.Electrochemical cathodic protection (magnesium anode) method is difficult to guarantee that all there is sufficient protection at each position to scatterer; Electroplate and electroless plating, it is bigger to implement difficulty, and cost is also higher relatively; Add the method for inhibiter and can only slow down corrosion to a certain extent, and will be at different system, different quality, research is effectively inhibiter and suitably addition accordingly, and this operational management to system has also proposed a difficult problem.Comparatively speaking, the application of coating (method with can is implemented) is easier.After the scatterer welding fabrication, by can internal surface is carried out pre-treatment and cleaning fully, oven dry can be carried out the application of coating.The key of this method is to select suitable coating.The sticking power of coating high temperature resistant alkaline water corrosive nature and coating and protected metal is that coating is selected the key technical indexes.
The scatterer inner side anticorrosion coating of developing at present is by the TY3381 of Wuhan Inst. of Material Protection; its main component is phenol aldehyde modified Resins, epoxy; its maximum shortcoming is that smell is excessive, is unfavorable for environment protection and operator's health.In addition, when envrionment temperature was lower than 15 ℃, it was mobile poor, should not construct, and sticking power is relatively poor on steel radiator, can not satisfy shortcomings such as scatterer erosion resistance requirement.
