Abstract

The invention provides a double-component aqueous nano scratch resistant wood coating and a method for producing the same. The wood coating comprises an A component and a B component, wherein the B component consists of the following raw materials in percentage by weight: 75 to 90 percent of aqueous nano resin, 0.1 to 1 percent of defoamer, 0 to 3 percent of dulling agent, 0.1 to 1 percent of thickener, 1 to 5 percent of film-forming assistant, 0.1 to 0.5 percent of wetting agent, 1 to 5 percent of aqueous nano scratch resistant agent, 1 to 5 percent of aqueous nano wax emulsion, 0.1 to 0.3 percent of pH adjusting agent, and 1 to 5 percent of water. The double-component aqueous nano scratch resistant wood coating has the advantages that: the wood coating is low in VOC, almost tasteless anddiluted by water; and except good physicochemical properties, the wood coating also has extremely good scratch resistance.

Description

Double-component aqueous nano scratch resistant wood coating and production method thereof
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 production 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, by 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 by 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.
