Description
Technical field
The present invention relates to a kind of roller coat waterborne zinc-rich shop primers and preparation method thereof, belong to chemical paint field.
Background technology
Starting within 2007, Zhong Ji groups are first begin to test and pre-process roller application technique using container steel plate, with
Afterwards several years, this technique was promoted the use of by multiple producers in container industry, until today, two component epoxy zinc rich primer conduct
Shop primer is used for pre-coated steel plate, it has also become a kind of highly developed technique.Into 2017, Environmental Protection in China pressure was increasingly
Seriously, coating industry " oil changes water " and " full Water-borne modification " have to bring into schedule, and in current technique, make as shop primer
Solvent-based two-component epoxy zinc-rich also starts on April 1st, 2017, is prohibited from using in Zhong Ji groups.Therefore, it is a kind of
It is suitable for the water-based zinc rich primer of roller coating technology, becomes the necessary selection in market.De Wei, in the remote Northwest, Wei Shibai, contain lion etc.
Coating material production producer, the roller coat for all successively having attempted waterborne zinc-rich as shop primer is tested, but all there is more or less
Disadvantage：Coating layer thickness cannot keep stable, and drying time cannot meet the requirement of client's production line, coating spread and uniformity
, there is flash rusting in shortcoming, rust spot etc. occurs within the time for placing requirement.The presence of these problems limits waterborne zinc-rich conduct
Popularization and development of the shop primer in terms of PRETREATMENT PROCESS OF STEEL BOARD OF CONTAINER, it is Water-borne modification to constrain container steel plate pretreatment
Process.
The content of the invention
Goal of the invention：The technical problems to be solved by the invention are in view of the deficiencies of the prior art, to provide one kind for collecting
Waterborne zinc-rich shop primer that roller coating technology can be used of vanning and preparation method thereof.
In order to solve the above-mentioned technical problem, the invention discloses a kind of roller coat waterborne zinc-rich shop primer, including as follows
The component of weight percentage：
Further, which is preferably as follows the component of weight percentage with waterborne zinc-rich shop primer：
Wherein, the water-base resin is resin dedicated for inorganic silicate modified water-soluble zinc-rich, preferably purchased from Wuxi Ou Mode
The model HW-100 water-base resin products of Chemical Co., Ltd..
The dispersant is modified polyacrylate polymer, preferably purchased from angstrom husband's Kona auxiliary agent (Jiangsu) Co., Ltd
4560 dispersant product of model.
The wetting agent is purchased from the high auxiliary agent of TEGO enlightening, model 4100.
The antifoaming agent is purchased from angstrom husband's Kona auxiliary agent (Jiangsu) Co., Ltd, model PD 524.
The coagent slurry is purchased from Wuxi Hu Huangqi industry Co., Ltd, model HW-101M.
The huge sum of money mountain flour is purchased from Heshan chemical industry (Huzhou) Co., Ltd, model SM-K100.
The zinc powder is 500 mesh, purchased from Yangzhou Shuangsheng Zinc Industry Co., Ltd..
The present invention also provides the roller coat preparation methods of waterborne zinc-rich shop primer, include the following steps：
Step 1：Water-base resin, dispersant, wetting agent and antifoaming agent are mixed, stirred evenly；
Step 2：In the mixture that coagent slurry is added to obtained by step 1 under stirring, continue to be dispersed to mixed
Close material fineness≤10 μm；
Step 3：Huge sum of money mountain flour and zinc powder are added in the mixture that step 2 obtains, continue to be uniformly mixed；
Step 4：The material that step 3 is obtained crosses 100 mesh filter screens, obtains masterbatch；
Step 5：The masterbatch water use regulation viscosity that step 4 is obtained to get.
For container, shop primer is a kind of protective coating of precoating property, it owns except waterborne zinc-rich primer
Characteristic outside, also thickness of dry film (in other words ensures all properties on the premise of, get over Bao Yuehao) of the requirement no more than 10 μm has
It is good to prevent resistance to flash rusting, there are good cutting performance and welding performance, while in the case of low film thickness, there is good corrosion resistant
Corrosion energy.Roller coat Ou Mode waterborne zinc-rich resins used in being formulated with waterborne zinc-rich shop primer, it is exactly special for roller coat
The product of door exploitation, uniformly leak source, guarantee precoated shet thickness of dry film do not reach 7 to paint film when cooperation coagent slurry can reach roller coat
μm and with good welding and cutting performance.Ou Mode waterborne zinc-rich resins, excellent with wettability, rate of drying is fast,
The characteristic that adhesive force is good, the principal security rate of drying and adhesive force of film.And coagent slurry can make resin and antirust
Antiseptin body forms homogeneous system, so as to during roller coat uniform adsorption spread on the surface of cylinder wheel and electric light wheel,
A kind of continual continuous phase is formed, coating is solved and is being not easy the uniform disadvantage of spread when too thin on roller and electric light wheel,
The final film forming thickness that ensure that dry film.The micro- charge adsorption and have both the uniform spread performance of superpower powder that coagent is starched
And the thixotropic property to system, it finally ensure that the possibility of roller coat and the various physicochemical properties of follow-up film, while this
Coagent slurry can inhibit the generation of moment flash rusting during coating, indispensable in entire formula.
Advantageous effect：
1st, the application waterborne zinc-rich shop primer can be solved using special coagent slurry cooperation waterborne zinc-rich resin
The rheological property of standard aqueous zinc-rich paint is poor, zinc powder is loosely layered, zinc powder is unevenly distributed, coating spread poor performance, electric light
Wheel adsorbs the problem of poor coating and uneven, coating and substrate wettability difference and zinc powder settling powder liquid separate, and is completely suitable for roller
Apply technique.
2nd, the thickness of dry film that the application waterborne zinc-rich shop primer is obtained using roller coating technology can be controlled in 7~10 μ ms
Within, coating 2 minutes surface dryings under the conditions of 35 DEG C, entire coating without flash rusting occur, with 15 times amplification sem observations, entire coating without
Holiday phenomenon occurs, construct no barrier excellent with the ply adhesion of rear road coating for 30 days in coated article nature holding chamber without rust spot
Hinder.
3rd, the application waterborne zinc-rich shop primer can be coated using roll coating model, thus convenient for the flowing water of container
Line produces.
