Plastics coating available paint kind is a lot, and representational is polyurethane lacquer, acrylic paint, vinyl resin paint and various types of epoxy resin-based paint.But its solvent of paint that is used for plastics coating at present is poisonous organic solvents such as lacquer thinner, toluene, dimethylbenzene, and the solvent of paint mainly helps out in film forming process, evaporate fully when film forming, at the application scene, the toxic gas that evaporates is difficult to eliminate, there is problem of environmental pollution, its toxicity is big, contaminate environment, and the harm painter's is healthy, easily bring out occupational illness, simultaneously, it is inflammable and explosive, has hidden fire-fighting danger.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of water-miscible paint that is used for plastics coating is provided, the present invention is based on water-base resin and water-based paint, with water is solvent, with the aqueous promoter is auxiliary material, no waste gas produces, and has fundamentally solved the environmental pollution, hidden fire-fighting danger and the occupational illness problem that are used for the paint of plastics coating at present.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of water-miscible paint that is used for plastics coating of the present invention, the parts by weight of raw materials proportioning of described water-miscible paint is: 8～20 parts of aqueous color pastes; 40～80 parts of water-base resins; 0～2 part of defoamer; 0～2 part of flow agent; 5～10 parts of membrane-forming agents; 0～2 part of sanitas.
The parts by weight of raw materials proportioning of aqueous color paste of the present invention is: 25 parts of pigment; 40～50 parts of water-base resins; 35～50 parts in water; 0.5～3 part of wetting agent.
Water-base resin of the present invention is a waterborne polymeric water dispersion acrylic resin; Described defoamer is the water-based defoamer; Described flow agent is the water-based auxiliary rheological agents; Described membrane-forming agent is auxiliary film forming aqueous solvent; Described sanitas is for preventing the corrosive aqueous solvent that goes mouldy.
Pigment of the present invention is that water is the carbon black aqueous color paste of solvent.
The present invention discloses a kind of described preparation method who is used for the water-miscible paint of plastics coating, it comprises the following steps:
1), the preparation of aqueous color paste
2), under whipped state, add water-base resin, defoamer, flow agent, membrane-forming agent and sanitas in hydrotropisms's mill base respectively.
Preparation method of the present invention, the preparation process of described aqueous color paste is: select pigment, add entry, wetting agent and water-base resin under whipped state, grind.
The acting as of each component among the present invention:
Water-base resin: play a major role in water-miscible paint, the solvent in the resin is a water
Aqueous wetting agent: effectively reduce the interfacial tension between wetted media and the pigment, make surface of pigments be modified.Make pigment obtain good dispersion stabilization
Water-based defoamer: suppress the generation of bubble in production and the construction process, and the bubble that produces is had extraordinary removing and shattered to pieces ability
The water-based flow agent: the viscosity in the raising system, under the low shear rate has excellent sag resistance and anti-pigment settling property
Water-borne preservative: excellent antibacterial, sterilization effect are arranged.
The present invention is used for the water-miscible paint of plastics coating, does not fire, not quick-fried, environmental protection, does not have the paint occupational illness.Simple to operate, the film forming levelling is good, and the smooth finish of filming after the film forming is good, do not have the tangerine line substantially.Strong adhesion, cross-hatching reach 100%, the hardness height, reach pencil hardness HB～H level, and water-tolerant soaked the normal-temperature water the inside more than 96 hours, and ageing-resistant performance is good, UV resistant is tested more than 480 hours.The present invention directly uses, and is simple to operate.Over-all properties is outstanding.
Advantage of the present invention is:
Film forming properties of the present invention is outstanding, uses simple, convenient
Wastewater treatment is simple, and cost is low, and the efficient height is easy to realize qualified discharge
Substantially do not have exhaust emission, VOC reaches national peak demand
Do not burn, no potential safety hazard
No triphen, nothing paint occupational illness
The present invention's operation is simpler, very good at the film forming sticking power on ABS, polyphenyl (PS), the poly-carbon plastic component such as (PC), reaches cross-hatching 100%.More outstanding on the levelling of filming, salient features such as ageing-resistant than present paint.
This coating can be directly used in the application of various surface of plastic products, easy construction, and cost is low; Effectively reduce environmental pollution; The coating adhesion, water tolerance, solvent resistance, the good weatherability that form, hardness is higher, and glossiness, fullness ratio are good, and surface of plastic products is played good decoration and provide protection; The filmogen of coating is all nontoxic; Coating property is stable, can be long time stored.
Using method of the present invention is: this product directly joins product of the present invention in the jar of spray gun without any need for adjustment, adopts conventional aerial spraying mode to operate.
At present the paint series products also is to adopt conventional aerial spraying mode, and difference is that present paint needs with organic solvent dilutings such as lacquer thinner before spraying, and what have also will add solidifying agent etc. temporarily, adds after filtering then in the jar of spray gun to use again.
Precaution in the use: product of the present invention can not be used with paint or other any organic solvents.
The present invention can be handled by the film forming clean-out system, and the film forming clean-out system is made up of water and anti-film coalescence aid, and the quality proportioning is 90: 8～15.
Waste water of the present invention can be handled with waste water conditioner, and waste water conditioner is made up of decolor flocculating agent and the discrete agent of resin, and the quality proportioning is 0.5～2: 40～60.
