Abstract
The invention relates to the technical field of machining of parts of a car, in particular to a spraying method for the inner wall of a water tank of the car. A pretreating agent is sprayed to the inner surface of the water tank of the car, and a protection film with the thickness ranging from 0.5 mm to 2 mm is formed; the water tank of the car is dried again, and the drying temperature is 80 DEG C; a Teflon nano-film with the thickness ranging from 0.1 micrometer to 0.5 micrometer is then sprayed to the surface of the protection film in the water tank of the car; and the nano-film is put into a constant temperature furnace to be dried for 5 hours, and the temperature in the constant temperature furnace is 55 DEG C. According to the spraying method, the operation process is concise, then the steps of spray pretreatment through the pretreating agent and spraying are executed, and the formula of the pretreating agent and the spraying process parameters are reasonably designed, so that the adhesive force of the Teflon nano-film is higher, and the service life of the product is prolonged.
Description
Technical field
The present invention relates to auto parts and components processing technique field, specifically relate to a kind of radiator inner wall spraying method.
Background technology
In order to better improve the structural behaviour of radiator and extend its service life, the mainly nano thin-film of wall spraying within it, to provide its structural strength.But due within it surface only spray-coated film, and do not adopt protecting film substrate, in use for some time, the film on surface taking off gradually, produces considerable influence by the structural behaviour of radiator to the product after spray process like this.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of radiator inner wall spraying method, for achieving the above object, present invention employs following technical scheme:
A kind of radiator inner wall spraying method, step is as follows:
Step 1., the spot of erasing radiator inwall, then to rinse with water, then dry;
Step 2., pretreating agent is sprayed into the inner surface of radiator, forming thickness is the protecting film of 0.5-2mm;
3., by radiator step dries again, and bake out temperature is 80 DEG C;
The surface of the protecting film of step 4., in radiator sprays the polytetrafluorethylenano nano film that a layer thickness is 0.1-0.5 μm again;
Step 5., put into constant temperature oven dry 5 hours, constant temperature in-furnace temperature is 55 DEG C.
Preferably, the pretreating agent that 2. described step uses is made up of 20 parts of polyacrylate dispersions, 25 parts of furfural resins, 1.5 parts of hydrochloric acid, 0.3 part of uronic acid, 1 part of potassium chloride and 40 parts of water.
Preferably, the preparation method of the pretreating agent that 2. described step uses is: in container, first add 25 parts of furfural resins and 15 parts of water, stirs 5 minutes; Then slowly add 1.5 parts of hydrochloric acid, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 20 parts of polyacrylate dispersions and 10 parts of water, limit edged stirs, and stirs 5 minutes after interpolation; Then slowly add 0.3 part of uronic acid, limit edged stirs, and stirs 5 minutes after interpolation; Finally slowly add 1 part of potassium chloride and 15 parts of water, stir 10 minutes.
Beneficial effect of the present invention shows:
1), the pretreating agent that uses in spraying method, its formula Design is reasonable, novel, particularly with the addition of a small amount of uronic acid, can significantly improve the treatment effeciency of pretreating agent.By pretreating agent with the use of, make radiator when follow-up spraying polytetrafluorethylenano nano film, polytetrafluorethylenano nano adhesion of thin film is stronger, then improves the service life of product.
2), the preparation method of pretreating agent, by the method for progressively adding, the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, the pretreatment potentiality of pretreating agent is promoted significantly.
3), the spraying method of radiator, operating procedure is succinct, focus on the step spraying pretreatment by pretreating agent and then carry out spraying, by formula and the spraying parameter of appropriate design pretreating agent, thus make polytetrafluorethylenano nano adhesion of thin film stronger, then improve the service life of product.
