Abstract
A method for protecting processed surfaces includes the following steps: step 1, spraying or coating a layer of protective membrane basic solution on a processed surface, wherein the protective membrane basic solution is composed of 85%-98.2% of polyving akohol aqueous solution, 0.8-5% of stabilizing agent, 0.5-4% of emulsifier and 0.5-6% of plasticizer; and step 2, removing water in the protective membrane basic solution to obtain a protective membrane. The method has excellent membrane forming performance, can have a buffer function between drills and surfaces to be processed of materials like metal panels, glass and hard plastic, reduces abrasion of machine drills and prolongs service life of machines.
Description
Technical field
The present invention relates to a kind of method of protecting machined surface, particularly a kind of preparation method who protects the environment-friendly water-soluble protective membrane of machined surface, its surface that can be used for sheet materials such as metal, glass, plastics adds the surface protection in man-hour hole, engraving etc.

2, in the such scheme, the viscosity of said polyvinyl alcohol water solution is 800 ~ 6500cps.Z 150PH (polyvinyl alcohol PVA) is a kind of monomer polymerization of can't help, but the water-soluble polymers that obtains through the PVA hydrolysis.The mass percentage concentration of polyvinyl alcohol water solution reaches at 12% ~ 28% o'clock, and viscosity can reach 800 ~ 6500cps.
3, in the such scheme, the general formula of sodium polyphosphate is Na
(n+2)P
nO
(3n+1), it is a kind of of polymeric phosphate, comprises that tripoly phosphate sodium STPP, five sodium polyphosphates, hexapolyphosphate sodium are so that higher sodium polyphosphate.
4, in the such scheme, the thickness of said protective membrane stoste is 10 ~ 200 microns.
5, in the such scheme, in second step, said protective membrane stoste is heated to 30 ~ 80 ℃, removes the moisture film that is protected.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, the present invention can form at the work surface of materials such as sheet metal, glass, rigid plastics and have snappiness excellent protection film, and behind boring and sculpting operation, can use water elution easily.
2, the present invention has excellent film-forming properties, can between the work surface of materials such as sheet metal, glass, rigid plastics and drill bit, form shock absorption, reduces the wearing and tearing of machine drill bit, prolongs the work-ing life of machine.
3, because the present invention has shock absorption, thereby guaranteed the dimensional stabilizing of product, enhanced productivity.
