Description
Technical field
The invention belongs to surface cleaning technical fields, and in particular to a kind of surface treatment method of the hard foamed materials of PU.
Background technology
Before the hard foamed materials of PU carry out application, in order to ensure painting effect, it is necessary to first be located in advance to workpiece surface
Reason its purpose is to remove the releasing agent of workpiece surface, dirt slag, cleans workpiece surface, in case coating adheres to after application
Power is bad, depainting phenomenon occurs.
The methods of method for PU foaming materials workpiece pre-process before application at present generally comprises polishing, solvent cleans.
PU foaming materials are in specific die for molding, and shape is ever-changing, complicated, and polishing can only handle the work of simple shape
Part surface, and polishing can not avoid releasing agent from polluting completely；The method of solvent cleaning is and right there are serious fire hazard
Environment pollutes, and has very big harm to the health of operating personnel, therefore urgently exploitation is a kind of simple for process, general
The strong and environmentally friendly workpiece surface treatment technology of property.
The content of the invention
In order to overcome shortcoming and defect in the prior art, it is an object of the invention to provide a kind of PU is hard foamed
The surface treatment method of material, this method is simple for process, and environment friendly and pollution-free.
The purpose of the present invention is achieved through the following technical solutions：A kind of surface treatment side of the hard foamed timber-used molds of PU
Method, it is characterised in that：Include the following steps：
(1), with the back side of the sand paper polishing hard foamed materials of PU；
(2), after being conserved within 8-10 days or being polished in the environment of the hard foamed materials of PU after polishing being placed in 40-50 DEG C
The hard foamed materials of PU be placed in outdoor drying 25-35 days；
(3), quartz sand is dispersed in warm water and obtains spray coating liquor, the temperature of the warm water is 40-50 DEG C；
(4), sprayed with PU hard foamed material surface of the spray coating liquor of gained in the step (3) in step (2) after maintenance
It applies one time, it is spare.
The back side of the present invention sand paper polishing hard foamed materials of PU is conducive to generation bleed passage, release PU foaming materials exist
The gas that device generates is conserved, effectively avoids the bubbling phenomenon of coating after application；The hard foamed materials of PU are sprayed with the spray coating liquor
Surface, on the one hand can more effectively remove releasing agent, on the other hand can by the back side feather plucking of the hard foamed materials of PU, increase coating
With the contact area of the hard foamed materials of PU, so as to improve the adhesive force of coating, ensure coating quality.
Wherein, sand paper is 60-80 mesh sand paper in the step (1).
Wherein, quartz sand is the quartz sand for adding 20-50 mesh in the step (3).
Wherein, sand-blasting machine spraying or hand spray can be used in the step (4) during spraying.
The beneficial effects of the present invention are：The surface treatment method of the present invention is simple for process and environment friendly and pollution-free, passes through
After the spray coating liquor spraying polishing of configuration, by back of work feather plucking, the contact area of coating and workpiece is effectively improved, so as to carry significantly
The adhesive force of high coating ensures coating quality.
Specific embodiment
