Waterborne edge sealing paint and complete processing thereof
Technical field
The present invention relates to a kind of water-miscible paint, especially relate to a kind of waterborne edge sealing paint and complete processing thereof that does not contain heavy metal, no free TDI, environmental protection.
Background technology
At present traditional edge sealing of furniture paint mainly contains PU polyester paint and two big types of NC pyroxylin(e)finishs, and wherein PU polyester paint construction environment requires highly, and paint film damages and is difficult for repairing, and it is restricted duration of service to join the lacquer back, and interlayer must be polished, the ratio requirement strictness; The relative PU lacquer of NC pyroxylin(e)finish is than environmental protection, but paint film is thin, and wear resistant and impact resistant power is not poor, and plentiful effect difficulty is made, and the construction pass is many, and painting cost is high, easy ageing etc.They all are to be main film forming substance with vegetables oil, synthetic resins; Be aided with various auxiliary agents and pigment, wherein also contain tolylene diisocyanate (TDI), must add organic solvent dilutings such as toluene, YLENE during use; These organic solvents human body harmful pollutes the environment.
Summary of the invention
To problem set forth above, the object of the invention is to provide a kind of waterborne edge sealing paint that does not contain heavy metal, no free TDI, environmental protection.
The present invention realizes through following technical measures; A kind of waterborne edge sealing paint; Combined by water, aqueous dispersant, aqueous wetting agent, water-based skimmer, calcined kaolin, water-ground limestone, rutile titanium white powder, Triple Pressed Stearic Acid zinc powder, superfine talcum powder, water-based aliphatic polyurethane resin, water-borne acrylic resin, film coalescence aid, terepthaloyl moietie, flow agent, sterilant and thickening material, wherein the parts by weight of each component are:
The preferred water-based dispersing agent C of aqueous dispersant N-528 wherein; The preferred aqueous wetting agent CF-10 of aqueous wetting agent, the preferred film coalescence aid Texanol of film coalescence aid, the preferred flow agent RM-2020 of flow agent; Thickening material preferred thickener RM-8W, sterilant preferred fungicide K9N.
Its complete processing is:
(1), the water of above-mentioned half weight and whole aqueous dispersant, aqueous wetting agent, water-based skimmers are added in a mixing bowl, use 400~800 rev/mins rotating speed stirring that each component is mixed;
(2), successively in a mixing bowl, add calcined kaolin, water-ground limestone, rutile titanium white powder, Triple Pressed Stearic Acid zinc powder and superfine talcum powder, and stirred 30 minutes, make the fineness≤30 μ m of mixture at 600~1200 rev/mins rotating speed;
(3), again in a mixing bowl, add water-based aliphatic polyurethane resin and water-borne acrylic resin successively after 600~1200 rev/mins rotating speed stirs 5~10 minutes, add film coalescence aid, terepthaloyl moietie, flow agent and sterilant, each component is mixed;
(4), stir down at last, adding thickening material and remainder water are adjusted to and carry out product examine after the required viscosity and be packaged into final product in a mixing bowl at 600~1200 rev/mins rotating speed.
The present invention be do not contain heavy metal, do not have free TDI, be the true health environmentfriendly products; High solids content, high fillibility, good difficult the falling into of hardness; Closure is good, have fabulous sticking power, the paint film densification is not easy to crack, when construction, have fast do, be prone to polishing, not scab paper, easy construction also can with the matching used advantage of various finish paints.
Embodiment
Below in conjunction with embodiment the present invention is done further explain.
Waterborne edge sealing paint is processed by 20kg water, 0.3kg aqueous dispersant, 0.2kg aqueous wetting agent CN-528,0.2kg water-based skimmer CF-10,10kg calcined kaolin, 20kg water-ground limestone, 15kg rutile titanium white powder, 2kg Triple Pressed Stearic Acid zinc powder, 4kg superfine talcum powder, 15kg water-based aliphatic polyurethane resin, 10kg water-borne acrylic resin, 2kg film coalescence aid Texanol, 0.6kg terepthaloyl moietie, 0.2kg flow agent RM-2020,0.1kg sterilant K9N and 0.4kg thickening material RM-8W;
Its production technique is:
(1), the water of above-mentioned 10kg and 0.3kg aqueous dispersant, 0.2kg aqueous wetting agent CN-528 and 0.2kg water-based skimmer CF-10 are added in a mixing bowl, use 600 rev/mins rotating speed stirring that each component is mixed;
(2), successively in a mixing bowl, add 10kg calcined kaolin, 20kg water-ground limestone, 15kg rutile titanium white powder, 2kg Triple Pressed Stearic Acid zinc powder and 4kg superfine talcum powder, and stirred 30 minutes, make the fineness≤30 μ m of mixture at 1000 rev/mins rotating speed;
(3), in a mixing bowl, add 15kg water-based aliphatic polyurethane resin and 10kg water-borne acrylic resin more successively after 1000 rev/mins rotating speed stirs 5~10 minutes; Add 2kg film coalescence aid Texanol, 0.6kg terepthaloyl moietie, 0.2kg flow agent RM-2020 and 0.1kg sterilant K9N, each component is mixed;
(4), stir down at last, adding 0.4kg thickening material RM-8W and remainder water are adjusted to and carry out product examine after the required viscosity and be packaged into final product in a mixing bowl at 1000 rev/mins rotating speed.
More than be that the prescription and the making method of waterborne edge sealing paint of the present invention are set forth; Be used for helping to understand the present invention; But embodiment of the present invention is not restricted to the described embodiments; Any change that does not deviate under the principle of the invention to be done, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within protection scope of the present invention.
