Abstract
The invention relates to the technical field of automobile part processing, in particular to a method for preparing a pretreating agent applied to spraying of an inner wall of an automobile water tank. The method comprises the following steps of firstly adding 25 parts of furfural resin and 15 parts of water into a container, and stirring for 5 minutes; then slowly adding 1.5 parts of hydrochloric acid while stirring, and stirring for 5 minutes after the completion of the adding operation; then slowly adding 20 parts of polyacrylate emulsion and 10 parts of water while stirring, and stirring for 5 minutes after the completion of the adding operation; then slowly adding 0.3 parts of uronic acid while stirring, and stirring for 5 minutes after the completion of the adding operation; finally slowly adding 1 part of potassium chloride and 15 parts of water, and stirring for 10 minutes. The preparation method provided by the invention has the advantages that not only can the dissolving properties of all substances be improved, but also the possibility of particle agglomeration can be prevented through a method of gradually adding, therefore the pretreatment capability of the pretreating agent is significantly improved.
Description
Technical field
The present invention relates to automobile component processing technique field, specifically relate to a kind of preparation method of the pretreating agent for radiator inner-wall spraying.
Background technology
In order to better improve the structure properties of radiator and extend its work-ing 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 protective film substrate, in use for some time, the film on surface taking off gradually, produces considerable influence by the structure properties 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 preparation method of the pretreating agent for radiator inner-wall spraying, for achieving the above object, present invention employs following technical scheme:
For a preparation method for the pretreating agent of radiator inner-wall spraying, in container, first add 25 parts of furfuryl resins and 15 parts of water, stir 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 Repone K 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 formulating of recipe is reasonable, novel, particularly with the addition of a small amount of uronic acid, can significantly improve the processing efficiency 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 work-ing 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 pre-treatment 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 work-ing life of product.
Embodiment
Below with reference to embodiment, the present invention is described in detail.But; embodiment content is only citing made for the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
One, the composition of pretreating agent
20 parts of polyacrylate dispersions, 25 parts of furfuryl resins, 1.5 parts of hydrochloric acid, 0.3 part of uronic acid, 1 part of Repone K and 40 parts of water.
Two, the preparation method of pretreating agent is:
First in container, add 25 parts of furfuryl resins and 15 parts of water, stir 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 Repone K and 15 parts of water, stir 10 minutes.
Three, for the preparation method of the pretreating agent of radiator inner-wall spraying, 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 internal surface of radiator, forming thickness is the protective film of 0.5-2mm;
3., by radiator step dries again, and bake out temperature is 80 DEG C;
The surface of the protective 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.
