Description
Technical field
The present invention relates to Application Areas prepared by water-borne coatings, particularly relate to a kind of wetting agent.
Background technology
Water-borne coatings refers to the coating using water as solvent or make dispersion medium, comprises water soluble paint, water-reducible coatings, water-dispersible paint (latex coating) three kinds.Water soluble paint take water soluble resin as film forming matter, with polyvinyl alcohol and various modifier thereof for representative, in addition also has water-soluble Synolac, water-soluble epoxy resin and inorganic polymer water-base resin etc.The color stuffing that water-borne coatings uses must keep higher chemical stability in water, therefore, this color stuffing preferably inertia and water-soluble unduly, and select different grain size, difform filler according to the use of coating and performance requriements.
Color stuffing grinding wetting agent makes to roll into a ball by second particle the inorganic color stuffing formed to be able in aqueous phase grinding distribution process by a kind of material soaked rapidly, by reducing surface (interface) tension force of water, making inorganic color stuffing fully be soaked by water under certain shearing rate and revert to precursor rapidly, is a kind of product be widely used in water-borne coatings preparation.
Pour point (Pour point) refers to that oil product under prescribed test conditions, the minimum temperature that cooled sample can flow, and DEG C to represent, is used to weigh the conventional index lubricating wet goods low-temperature fluidity.Pour point is one of parameter of the quality of reflection oil low-temperature mobility, and pour point is lower, and the low-temperature fluidity of oil product is better.Therefore, people can according to the height of oil pour point, the measure considered to transport under cryogenic, store, take when receiving and dispatching, and also can be used for assessing the low temperature use properties of some oil product.
At present, the general wetting agent of coating industry is alkylphenol polyoxyethylene, and because environmental grounds is replaced by fatty alcohol-polyoxyethylene ether, but the pour point of fatty alcohol-polyoxyethylene ether is higher, just lose flowability when being usually less than 10 degree Celsius, this uses to the coating in the area that makes a clear distinction between the four seasons and makes troubles; In addition, this type of material whipability is higher, and dynamic surface tension is higher, causes the negative effect of steady bubble to speed lapping dispersion or application.Branched-chain alkyl polyvalent alcohol pectination oxyethyl group ether is owing to containing comparatively poly-hydroxy, and easily the oxidized wetting effect that causes reduces.Therefore, the wetting agent that a kind of pour point of exploitation is low, be applicable to low temperature season use is needed badly.
Summary of the invention
For the problems referred to above, the invention provides a kind of wetting agent, this wetting agent is that different non-ionic surface active materials is prepared into mixture, makes pour point drop to lower than subzero 12 DEG C, and effectively reduce foam stability, thus meet in low temperature season preparation and the processing requirement using water-borne coatings.
For realizing above-mentioned purpose of the present invention, the invention provides a kind of wetting agent, be made up of the raw material of following parts by weight: branched-chain alkyl polyvalent alcohol pectination oxyethyl group ether 40-50 part, fatty alcohol-polyoxyethylene ether 20-40 part, catechin 6-10 part, thearubigins 0.1-0.5 part, nano molecular sieve 3-10 part, sanitas 1-5 part, defoamer 1-5 part, water 0.5-2 part.
Described sanitas is one or several in isothiazolinone derivatives, benzoglyoxaline ester class, Dao Weixier-75, BIT.
Described defoamer is one or several in polydimethylsiloxane, glycerine trihydroxy-polyethers, higher alcohols, GP type defoamer, GPE type defoamer.
The present invention also provides a kind of preparation method of wetting agent, and concrete steps are as follows.
Step 1, get branched-chain alkyl polyvalent alcohol pectination oxyethyl group ether and fatty alcohol-polyoxyethylene ether by composition of raw materials, be placed in dry there-necked flask, described there-necked flask is with electric blender, constant pressure funnel; Open and stir, stir 1-2h with the speed of 300-500r/min.
Step 2, get catechin, thearubigins, nano molecular sieve by composition of raw materials, be placed in dry there-necked flask, open and stir, stir 0.5h with the speed of 300-500r/min, obtain catechin, the thearubigins mixed solution with slow-release function.
Step 3, will have catechin, the thearubigins mixed solution of slow-release function, sanitas in step 2, defoamer, water joins in the there-necked flask in step 1 by constant pressure funnel, stirs 2h, obtain wetting agent finished product with the speed of 400-600r/min.
Compared with prior art beneficial effect of the present invention.
Wetting agent provided by the invention, that different non-ionic surface active materials is prepared into mixture, wherein, because branched-chain alkyl polyvalent alcohol pectination oxyethyl group ether is not containing APEO, not containing solvent, have good water-soluble, effectively can improve the dispersiveness of pigment, improve the color development performance of water-borne coatings, coating film gloss can be helped improve, and fatty alcohol-polyoxyethylene ether and water just can form more hydrogen bond, water-soluble all right, the branched-chain alkyl polyvalent alcohol pectination oxyethyl group ether of superior low temperature mobility and the synergistic of fatty alcohol-polyoxyethylene ether is had to use, make this wetting agent have lower quiet/dynamic surface tension, unstable bubble, low pour point, catechin has excellent radical-scavenging ability, and thearubigins itself has comparatively strong antioxidant action as the oxidation products of catechin, has good Scavenging activity to free radical scavenging activity (DPPH) free radical.Catechin and thearubigins effectively can solve the oxidizable shortcoming of this wetting agent, make this wetting agent obtain good antimicrobial property simultaneously.The special pore passage structure of nano molecular sieve makes it have slow releasing function, makes catechin and thearubigins can stablize permanent being present in this wetting agent.The pour point of this wetting agent drops to lower than subzero 12 DEG C, and effectively reduces foam stability, and then pumpable serves material at low ambient temperatures, meets the needs of industrialization automatic gauge.
