Description

Easily tear formula antirust liquid film, its preparation method and application
Technical field
The invention belongs to antirust field, it is related to a kind of rust-preventing film and in particular to one kind easily tears formula antirust liquid film, its preparation Method and application.
Background technology
Most machineworks, because equipment is due to being assembled using baking vanish part, electroplating part, metal parts, therefore need Will be for exposed metal parts antirust treatment.
Often using antirust oil or antirust agent in prior art, and paint Long Term Contact antirust liquid is easily produced Fade and bubble and come off, similarly can affect the secret worry of adherence for electroplating part, so optimal rust-proofing method is exactly Dry type is antirust, but because the equipment of the multi-element metal part assembling of this respect is that volume is big or baroque mostly, because This uses rust-preventing film of the prior art mostly to adopt the multiple structure of multi-layer co-extruded method preparation, and rust-preventing film has certain Thickness, the simple rust prevention packaging doing dry type for metal parts is processed, and there is inconvenience, is such as directed to baroque metal Surface cannot be by rust-preventing film uniformly parcel and metal surface.
Therefore, research one kind is easy to remove, and can be suitable for the rust-preventing film on different metal surface, has great importance.
Content of the invention
The technical problem to be solved in the present invention, is to provide one kind easily to tear formula antirust liquid film, forms thin film in metal surface It is easy to remove, and metal surface will not be produced with damage or produce bad impact.
Another goal of the invention of the present invention is to provide the preparation method easily tearing formula antirust liquid film, prepared by strict control Technical parameter in journey, ensures its film property and film formation time during antirust liquid film is formed.
Another goal of the invention of the present invention is to provide the application easily tearing formula antirust liquid film, and it can be used in metal surface Antirust, after being sprayed at metal surface, after 3-10min formed rust-preventing film.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
One kind easily tears formula antirust liquid film, and it is made up of the raw material of following percentage composition:
Liquid plasticses 80%, antirust agent 17%, dimethylethanolamine 3%.
As one kind restriction of the present invention, described liquid plasticses include the raw material of following parts by weight:
20 parts of pvc powder, 60 parts of 2-butanone.
In prior art, pvc powder is mainly used in preparation pvc plastics, and pvc plastic hardness is very high, and pure pvc plastics lead to Often apply and plug in the plastic wares such as disk casing in water pipe, flowerpot, power supply, if preparation film forming, such as daily printed film, industrial packaging Film, agriculture greenhouse film and heat shrink films etc.;All kinds of plates, sheet material (as Blister product), all kinds of tubing are (as nontoxic upper hose, building Penetration pipe, transparent hose etc.), all kinds of profile shapes (as door, window, decorative panel), hollow bottle blowing (as cosmetics and beverage), cable, All kinds of injection-molded items and artificial leather, flooring laminate, slush moulding toy etc.;And pvc should be used as at present thin for preservative film, thickness between 0.25-0.3mm.The present invention is used pvc powder as film former, 2-butanone solvent, and both effective combines the film-formation result being More preferably, and make the formula antirust liquid film that easily tears being formed have the characteristics that easily to tear.
As the restriction further of above-mentioned restriction, described liquid plasticses are prepared according to following steps order:
1. using 2-butanone as solvent, seal water proof and be heated to 35 DEG C, make solution a;
2. pvc powder is dividedly in some parts and stirs to the solution a being preheating to 35 DEG C, often adding will during next group pvc powder When the pvc powder of last consignment of addition is until be completely dissolved, until all pvc powder are completely dissolved, finally give liquid plasticses.
As the another kind restriction of the present invention, described antirust agent includes the raw material of following parts by weight:
4 parts of ethanedioic acid, 5 parts of benzotriazole, 6 parts of lauric acid/dodecanoic acid.
In the preparation process of antirust agent, the present invention with the addition of lauric acid/dodecanoic acid, and its effect is can to increase as pvc plasticiser Outdoor thermostability and elasticity, as antirust agent supporting body, benzotriazole is as the antirust antioxidation of multi-element metal for ethanedioic acid Agent.
As the restriction further of above-mentioned restriction, described preparation method is carried out according to following steps order:
Using ethanedioic acid as bearing substrate, seal water proof and be heated to 65 DEG C, add lauric acid/dodecanoic acid, stir 10 minutes, add Benzotriazole, stirs 30 minutes, is finally made antirust agent.
Present invention also offers the above-mentioned preparation method easily tearing formula antirust liquid film, it is carried out according to following steps order:
1. liquid plasticses sealing water proof is heated to 35 DEG C, adds dimethylethanolamine, stir 10 minutes, prepared liquid b;
2. antirust agent is dividedly in some parts in liquid b and stirs, and often adds and will add when last consignment of during next group antirust agent Antirust agent until being completely dissolved until completely fused add, until completely fused, eventually easily tear formula antirust liquid film.
Present invention also offers easily tearing the application of formula antirust solution, easily being torn formula antirust liquid film and being sprayed at behind metal surface, Form rust-preventing film after 3-10min, be applied to the antirust of metal surface.The described formula antirust solution that easily tears can be prepared in application The form of atomizing, brushing formula and immersion type, aerosol can single spin thickness is that (thickness can twice for spraying for 0.02-0.025mm Reach 0.04-0.05mm), hand brush or soak single operation thickness about slightly 0.05-0.06mm;The antirust time limit regards coating metal Determine after skin covering of the surface, the application more thick antirust time limit is longer.
Due to employing above-mentioned technical scheme, compared with prior art, acquired technological progress is the present invention:
Provided by the present invention easily tear after formula antirust liquid film is painted on metal surface, depending on working environment, weather condition, liquid Body rust-preventing film will 3~10min metal surface formed dryness protection film layer, this protection film layer can closely attached write in metal Surface, the rust-preventing film being formed can expose storage in atmosphere and put;The rust-preventing film being formed removes simplicity it is only necessary to tear manually i.e. Can divest easily, improve conventional surface application antirust oil, the contaminated wastewater of aqueous rust preventive cleaning operation generation, and simplify cleaning and make Industry, clean space, saving cost of human resources are it is easy to large-scale use.
The present invention is applied to the preparation easily tearing formula rust-preventing film, is further applied to the antirust of metal surface.
The present invention is described in further detail below in conjunction with specific embodiment.
