Compared with prior art, the invention has the advantages that：
One, the aqueous sealing primer for fat content ground high disclosed by the invention, curing agent in its raw material components The mixture of the modified polyamide of selection and a small amount of distearyl dimethylammonium hectorite, modified polyamide curing agent is both crosslinking agent It is again emulsifying agent, it mutually acts synergistically with inorganic polymer surfactant distearyl dimethylammonium hectorite, makes curing agent There is good compatibility with epoxy resin, the coating system latex particle particle diameter of formation is small, narrow distribution range, good penetrability, With preferable workability, can solidify in wet environment, and with crosslink density very high, form the relatively compact heavily fortified point of film Gu, it is strong to base material adhesive force, oil substances in ground are thoroughly closed with the external world, make this kind of material and top layer film completely every From, oil substances are prevented to exosmosis, eliminate film and the disadvantage such as heave, this is that existing aqueous sealing primer cannot be compared , so as to solve water-borne wood coating in coating process due to timber material complexity and influence film performance performance and The problem of the constructional difficulties for causing, has widened the range of application of aqueous woodware paint significantly, and conventional aqueous woodware paint is solved very well The deficiency of presence；
Secondly, the seal coat emulsifying agent is not used in preparation process, thoroughly solve standard aqueous coating water sensitive Sex chromosome mosaicism, it is ensured that its excellent properties, with excellent chemical-resistant and adhesive force, it exists with solvent based coating state, The problem of freeze-thaw stability and the stable storing difference often having in the absence of general water paint, with excellent storage stability；
Thirdly, this experimental selection replace part hydrotropy using hydrophilic active diluent C12~C14 alkyl glycidyl ethers Agent, reduces the VOC of system, and it plays dissolved dilution to epoxy resin, and co-emulsifier makes coating system more stable, improves During seal coat is to the wetting of ground basal plane and penetrating into base material, while it carries epoxide group participates in cross-linking and curing reaction, enter One step improves sealing effect and richness；Selection propylene glycol monomethyl ether, ethanol and a small amount of dry vegetable oil are used cooperatively as hydrotropy Agent, propylene glycol monomethyl ether environmental pollution is small, safe, and ethanol belongs to reproducible innoxious solvent, and dry vegetable oil is also nontoxic It is harmless, and in vegetable oil unrighted acid content it is many, many containing double key number in unrighted acid, activation capacity is strong, into Film speed is fast, therefore the seal coat has preferable drying property, and the paint film after doing does not soften, and conjunctiva is tough and tensile, water-fast, elasticity Good, not only toxicity is low for the cosolvent system, and pollution will not be produced to environment；
Four, fat content ground high of the present invention, can be pine, cypress, and especially scab more cypress, It should be understood, however, that the aqueous sealing primer for fat content ground high of the present invention, it is also possible to for other The ground of low grease content；
Furthermore, strictly control in the preparation method of the aqueous sealing primer for fat content ground high of the invention it is each anti- The technological parameter in the stage of answering, and using supersonic oscillations dispersion, disperse Quick uniform, accelerate to react, save the time, it is adaptable to work Industry metaplasia is produced.
Further advantage of the invention, target and feature embody part by following explanation, and part will also be by this The research and practice of invention and be understood by the person skilled in the art.
