Abstract
The invention discloses a method for making a tube-in-sheet bonded evaporator comprising an aluminum tube and an aluminum plate. The method comprises steps as follows: coating a layer of heat conducting adhesive film on the upper surface of the aluminum plate; arranging a two-component epoxy polyurethane corrosion protective coating prepared by a main agent and a curing agent according to a weigh ratio between 1:6 and 1:2 on the outer surface of the aluminum tube of the evaporator; drying the coating on the aluminum tube of the evaporator, and then carrying out a sulfur treatment; and finally bonding together and fixing the aluminum tube of the evaporator and the aluminum plate coating with the heat conducting adhesive film by heating and vulcanization. The two-component epoxy polyurethane corrosion protective coating has a white color or undertone color, with a thickness between 10 and 100 microns. As the two-component epoxy polyurethane corrosion protective coating is used for coating on the entire outer surface of the aluminum tube, the evaporator can effectively avoid the pitting corrosion at the joint between the tube and the plate. In addition, with lower cost than the harmful anodizing process, the evaporator can meet the environmental protecting requirements.
Description
Technical field:
The present invention is a kind of preparation method of bonding type plate pipe evaporator.
Background technology:
The preparation method of existing bonding type plate pipe evaporator is earlier with aluminium sheet and aluminum pipe bonding forming, again with plate pipe evaporator outer surface spary one deck anticorrosive paint layer of moulding.The shortcoming that the evaporimeter that this method is produced exists is that the anticorrosive paint layer fails to cover the pipe face is whole, causes that plate and pipe jointing place easily corrode in the use.And another kind of anodic oxidation because oxidation is lepthymenia, has the oxidation point and more crisp of leakage to the aluminum tube surfaces preservative treatment, easily corrodes.
Summary of the invention:
The purpose of this invention is to provide a kind of adhesive property that can improve pipe and plate, can play again and not stay the dead angle, the preparation method of the bonding type plate pipe evaporator of favorable anti-corrosion effect.
Technical solution of the present invention is finished as follows, it includes evaporimeter aluminum pipe and aluminium sheet, it is characterized in that: cover one deck conductive adhesive film at the aluminium sheet upper surface earlier, and at evaporimeter aluminum pipe outer surface dip-coating one deck by host and curing agent by 1: the two component epoxy polyurethanes anticorrosive paint layer that the weight ratio of 2-6 is made into, to carry out vulcanizing treatment after the oven dry of the dope layer on the evaporimeter aluminum pipe, at last evaporimeter aluminum pipe and the aluminium sheet that covers conductive adhesive film are adhesively fixed through baking.The color of two component anticorrosive paints is white or light two component anticorrosive paints.The thickness of two component anticorrosive paint layers is 10-100 μ m.Evaporimeter of the present invention is owing to adopt two component anticorrosive paints to cover the aluminum pipe whole outer surface, so the spot corrosion phenomenon of having avoided the tube sheet junction to exist effectively, cost is lower than the anode oxidation process that environment is had harm, has reached environmental requirement.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Preparation method of the present invention is, cover one deck conductive adhesive film 3 at aluminium sheet 4 upper surfaces of making evaporimeter earlier, and at outer surface dip-coating one deck of the aluminum pipe 2 of making evaporimeter by host and curing agent by 1: the two component epoxy polyurethanes anticorrosive paint layer 1 that the weight ratio of 2-6 is made into, the viscosity of coating is as the criterion at 12-16S, aluminum pipe after the dip-coating is hung isolation, in baker, after the oven dry, carry out vulcanizing treatment again, at last aluminum pipe and the aluminium sheet that is coated with conductive adhesive film are adhesively fixed with the baking method.The color of two component anticorrosive paints is good with white or light color.
