Description
Technical field
The invention discloses a kind of water-thinned Normal temperature Stripable paint, be applicable to that plant and instrument seals protection up for safekeeping, also can be used for the inter process workpiece protection of metal finishing industry, like operations such as application, plating.
Background technology
The peelable coating of sealing up for safekeeping is that of rising the forties in 20th century protects or seal up for safekeeping technology.Generally speaking, it is by formulated protective layers of component such as film forming matter, inhibiter, softening agent, solvents, adopts methods such as spraying, brushing and dip-coating to be coated on article surface, forms the resist of one deck compact structure.This resist penetrates into the article surface except stoping moisture and air, and inhibiter wherein has the composite protective effect, and is also flexible because of the coating softness in addition, mechanical collision in the time of standing to carry and friction.In the time need not coating, can at an easy rate coating be peelled off, very easy to use.Therefore, peelable seal up for safekeeping coating equipment seal up for safekeeping and products production processing transhipment in, have broad application prospects.
Traditional peelable coating of sealing up for safekeeping is divided into 2 big types: hot-melting type and solvent-borne type.Wherein, hot-melting type is generally made filmogen with cellulosics, under heating state, resin and softening agent, stablizer, rust-preventive agent, mould inhibitor and other subsidiary material of mineral wet goods is mixed.Need be heated to 140～180 ℃ during use, apply film forming after the fusion, thicknesses of layers is 1～2mm; Solvent-borne type generally with vinyl resins etc. as film forming material, add an amount of auxiliary agent, be dissolved in volatile organic solvent formulated.Apply film forming under the room temperature, thicknesses of layers is at 0.2～0.75mm.
Make a general survey of peelable development of sealing film up for safekeeping, two kinds of above-mentioned Stripable paint coatings are main with unitary film mainly, and the barrier property of single component film forming matter is not so good, and solvent-borne type is peelable, and to seal the environmental-protecting performance of coating up for safekeeping bad.For this reason, we have developed environment amenable emulsion-type Stripable paint in the present invention.
Summary of the invention
In order to solve the technical problem that exists in the prior art, the object of the present invention is to provide a kind of environment-friendly type to be used for the water-thinned Normal temperature Stripable paint that plant and instrument is sealed protection up for safekeeping.
The technical scheme that the present invention adopts is following:
Be used for plant and instrument and seal the water-thinned Normal temperature Stripable paint of protection up for safekeeping, it is characterized in that, form by following materials of weight proportions:
Preferably, said polyaminoester emulsion is to contain non-ionic hydrophilic segment or hydrophilic radical non-ionic type in the molecule.
Further, said polyaminoester emulsion solid content is 50 ± 1%, and the pH value is 7.5 ± 0.5, and emulsion particle diameter is not more than 200nm, glass temperature range-25～-5 ℃.
Preferably, said wetting dispersing agent is the PEMULEN TR2 sodium salt solution.
Preferably, said nano-sized filler is the nano titanium oxide that median size is 40nm.
Preferably, said skimmer gathers silica silicon and hydrophobic particulate mixture for broken bubble.
Preferably, said flow agent is polyether-modified YSR 3286 interpolymer solvent.
Preferably, said thickening material is the modified urea polyurethane soln.
The present invention is used for the water-thinned Normal temperature Stripable paint that plant and instrument is sealed protection up for safekeeping; On the basis of polyaminoester emulsion membrane formation mechanism; Through major ingredient such as polyaminoester emulsion and other film coalescence aid screening and composite, working out with polyaminoester emulsion is the water-thinned Normal temperature Stripable paint of main membrane-forming agent.Nontoxic, harmless, pollution-free, simple to operate, characteristics such as raw material sources are extensive, price is low, cleaner production that product has.
Preparation is used for the method that plant and instrument is sealed the water-thinned Normal temperature Stripable paint of protection up for safekeeping, it is characterized in that step is following:
Under 1200～1500rpm agitation condition, in the polyaminoester emulsion that is added with wetting dispersing agent, add nano-sized filler, disperse 2～2.5h with sand milling, dispersion, stirring multi-purpose machine, add skimmer, flow agent and thickening material more successively, promptly get after being uniformly dispersed.
Compared with prior art, the present invention is used for plant and instrument and seals the beneficial effect of the water-thinned Normal temperature Stripable paint of protection up for safekeeping and show:
1, product is the water-thinned Normal temperature Stripable paint, does not contain organic solvent composition basically, and is environmentally friendly, pollution-free.
2, the product film formation time is short, good leveling property.
3, product easy construction, film forming is even and basal body binding force is moderate, is easy to peel off.Detect through test: when coat-thickness is 0.13～0.14mm, (brush two roads), the coating average tensile strength reaches 9.51MPa, and average elongation at break reaches 274.54%, and peelable performance is best.
