Abstract
One hull processes technique, concretely comprises the following steps: utilize organic siliconresin and inorganic particle to make required sheet material and powder-type coating, the polishing rust cleaning of use sandblasting machine, sprayed protection epoxy primer, paste sheet material after drying, spray powder-type coating and sand flat.The organic siliconresin that the present invention uses can bring good waterproof and weatherability for hull, can reduce hull and carry out the frequency of surface treatment, and it is simply effective to process technique.
Description
Technical field
The invention belongs to hull surface processing technology field, be specifically related to one and utilize new coating that hull outer surface is processed so that it is waterproof is anti-corrosion, there is the process technique of good weatherability properties energy.
Background technology
On the earth, the area of about 71% is all ocean, marine resources are very abundant, but the area being because ocean is too wide, it is thus desirable to just can shuttle back and forth in ocean by various ships, if ship navigates by water in ocean for a long time and can not get safeguarding, hull is easy to, by sea water, marine atmosphere and marine organism corrsion or attachment, affect safety and the stability of boat trip.
In order to prevent hull exterior draft partial corrosion or be affected the navigation of ship by aquatic organism attachment, it is necessary to hull outer surface Timing Processing, prior art generally adopts and sprays paint or electric plating method.According to the method sprayed paint, hull outer surface being processed, layer of paint, under the immersion of sea water and the impact of marine climate, extremely easily comes off, and causes that the anti-corrosion effect of waterproof is very undesirable；Processing according to galvanoplastic, the time that not only processes is longer, once processing method is incorrect, also can affect the navigation of ship.
Therefore, work out and a kind of process process simple, waterproof is anti-corrosion excellent, be the new problems that require study of those skilled in the art.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of hull and process technique.
In order to achieve the above object, the present invention provides following technical scheme:
A kind of hull processes technique, it is characterised in that:
Concretely comprise the following steps:
(1) in pre-transform teactor, add matrix material, be polymerized including organic siliconresin, plasticizer and adhesive, be aggregated to the 70-95% of the phase inversion start point that conversion ratio is organic siliconresin plasticizer adhesive mixture；
(2) mixture formed in step (1) is easily separated, to generate the first logistics comprising the 75-90wt% of mixture in described step (1) and to comprise the second logistics of mixture in the step (1) that surplus is formed；
(3) in the second reactor, add the first logistics, be polymerized further, cause the inversion of phases of the first logistics；
(4) by inversion of phases the first logistics in step (3) and the second logistics of obtaining in step (2) with 25-33s-1Shear rate mix in static mixer, carry out second time inversion of phases, obtain organic siliconresin colloid；
(5) the organic siliconresin colloid obtained in step (4) is added in glue pot, adds inorganic particle and processing aid, be uniformly mixing to obtain the fluid-mixing of organic siliconresin and inorganic particle；
(6) fluid-mixing obtained in step (5) is imported extrusion in extruding machine, be fabricated to sheet material and powder-type coating after cooling with standby；
(7) use sandblasting machine to hull outer surface segmentation polishing rust cleaning；
(8) epoxy primer is protected in spraying temporarily；
(9) epoxy primer to be protected is dried, and the sheet material obtained in step (6) is pasted hull outer surface, and the junction of hull needs to reduce by half the thickness of sheet material；
(10) use the powder-type coating obtained in step (6) to be sprayed on sheet material, and sand flat.
First organic siliconresin, plasticizer and adhesive are joined in pre-transform teactor, carry out polyreaction.Form organic silicone plasticizer adhesive mixture；Add plasticizer and can improve the bending modulus of organic siliconresin, promote its toughness；Add when adhesive enables to organic siliconresin in the end cooling curing and there is enough intensity, and improve its viscosity, make it easier to combine with other products.And organic siliconresin has moisture resistance, waterproof, the cold-resistant and weatherability of brilliance, it it is outstanding super-hydrophobic base material.
The organic siliconresin plasticizer adhesive mixture that will be subsequently formed is separated into the first logistics and the second logistics, and the first logistics is carried out inversion of phases, remixes and carries out second time inversion of phases with the second logistics, forms organic silicone gels.
Being put in glue pot by the organic siliconresin colloid of formation afterwards, and add inorganic particle and processing aid, stir the fluid-mixing forming organic siliconresin with inorganic particle, by preparing sheet material and powder-type coating after extruding machine extrusion, cooling respectively.
Before pasting sheet material, it is necessary to use sandblasting machine that the outer surface of hull carries out polishing rust cleaning, and epoxy primer is protected in spraying temporarily, it is ensured that in processing engineering, corrosion will not occur hull outer surface further；After epoxy primer to be protected dries, first use sheet material that hull outer surface is pasted, it is contemplated that expanding with heat and contract with cold of hull surface, in the junction of hull, the thickness of sheet material is reduced by half；Finally again powder-type coating is sprayed on sheet material, and sand flat, completes hull surface and process.
As preferably, mass percent shared by organic siliconresin in step (1), plasticizer and adhesive is respectively as follows: 85-90%, 5-10%, 5-10%.
As preferably, mass percent shared by the constituent of the inorganic particle in step (5) and each composition is: TiO2: 45-60%, Al2O3: 30-40%, SiO2: 5-20%.
Use TiO2、Al2O3、SiO2As inorganic particle, it is possible to make the ship hull coating material of molding have a relatively low thermal coefficient of expansion, and outstanding moisture resistance, waterproof, the cold-resistant and weatherability of organic siliconresin can be kept.
As preferably, the constituent of the processing aid in step (5) and the mass percent of each composition be: bulking agent: 75-85%, stabilizer: 15-25%.
Adding bulking agent can by intermolecular bonding force so that organic siliconresin can be combined as a whole with inorganic particle, and then obtains stable mixture；Add stabilizer and can keep chemical equilibrium, reduce mixture surface tension, it is prevented that light, thermal decomposition or oxidation Decomposition etc. act on.
Compared with the present invention processes technique with existing hull, have the beneficial effect that (1) organic siliconresin can bring good waterproof and weatherability for hull；(2) reduce hull and carry out the frequency of surface treatment；(3) technique is processed simply effective.
