Description
Technical field
The present invention relates to a kind of bi-component waterborne woodwork coating, but refer in particular to a kind of water decentralized polymeric polyisocyanate solidified bi-component waterborne woodwork coating and working method thereof under normal temperature condition of making.
Technical background
Water-borne wood coating is the inevitable direction of of coating development; But because the water-borne wood coating rate of drying is slow; Filming seldom has crosslinked or reason such as cross-linking density is less; The physical and chemical performance and the solvent based coating that cause water-borne wood coating to be filmed have bigger gap, are especially influencing its development largely aspect hardness and the scratch resistance performance.Particularly in the field of furniture of some higher gears, the better hardness that requires to have filmed also will have resistance to marring preferably outward, and this makes water-borne wood coating make slow progress in a field.Although a lot of researchists turn to the bi-component waterborne woodwork coating to sight; Through adding waterborne curing agent; Increase the cross-linking density of filming and improve the physical and chemical performance of filming; This physical and chemical performance of filming than mono-component aqueous woodwork coating has had large increase, but still also has some gaps with solvent based coating.The present invention is further enhanced the film performance of water-borne wood coating, to satisfy the higher scratch resistance requirement of field of furniture through adding nano material.
Chinese patent CN101016431 discloses " a kind of nano antibacterial water woodenware paint and preparation method thereof "; This patent aqueous woodware paint is a single component; Nano material is to use as a kind of anti-biotic material, focuses on a technology difficult problem that solves free settling in the common inorganic antiseptic process of manufacture, easy to change and easy reunion.But the defective that this patent exists is that resistance to marring is poor.

Said thickening material is one or both in the association type polyurethane thickener, and its chemical composition is roughly association type urethane, can adopt the PU40 of German bright icepro company;
Said film coalescence aid can for more environmental protection, can adopt the propylene glycol kind solvent for alcohol ether kind solvent or alkoxide solvent, like the dipropylene glycol butyl ether (DPnB) of U.S. DOW company;
The preferred polysiloxane-polyether copolymer of said wetting agent, the trade mark that can adopt TEGO company is the product of TEGO245; Said skimmer and wetting agent are polysiloxane-polyether copolymer, and still, difference wherein is that the former wetting ability is poor, and latter's wetting ability will be got well;
Said aqueous nano scratch resistant agent, its staple are nano-aluminium oxide, and average nanometer particle size is 10～30nm, like the NMA-1 of Beijing initiative nanometer company;
Said water nano wax emulsion, the feel of filming with improvement is like 5001 oxidic polyethylene nanometer paraffin wax emulsion of Fushun Wen Ai company;
Said pH value regulator, pH value regulator is a 2-amino-2-methyl-1-propanol, like the AMP-95 of U.S. Mykrolis Corp;
But said water decentralized polyisocyanate curing agent is IPDI type or HDI type, and it is 50%～100% that weight contains admittedly, can adopt the Bayhydur XP2655 of German BAYER company.
Making method of the present invention comprises the steps:
(1) at first the water nano resin is added in the container, under agitation add skimmer, dispersed with stirring;
(2) secondly add matting agent and thickening material, and dispersed with stirring;
(3) add film coalescence aid, wetting agent, aqueous nano scratch resistant agent, water nano wax emulsion and pH regulator agent then, dispersed with stirring promptly obtains product for viscosity to 70～90KU/25 ℃ with thickening material and water adjustment at last.
Method of use of the present invention is to brush or spraying.
Double-component aqueous nano scratch resistant wood coating of the present invention has following advantage: low VOC, and almost tasteless, dilute with water, ambient cure is filmed except good physical and chemical performance is arranged, and also has fabulous resistance to marring.
