A kind of water-based white primer for bamboo wooden articles
Technical field
The present invention relates to chemical technology field, more particularly to a kind of water-based white primer for bamboo wooden articles.
Background technology
It is well known that bamboo wood substrate is due to containing flavones pigment, it is easy to induce in the market for bamboo wooden articles
Aqueous white coating turns yellow, so as to influence its painting effect.In general, natural flavonoid compound is more deposits in glycoside form
, and because sugared species, quantity, coupled position and connecting mode are different, various flavonoid glycosides can be constituted, together
When, due to cross conjugation system can be formed in the parent nucleus of flavone compound, and by electro transfer, rearrangement, make conjugated chain
Extension, thus bamboo wood substrate can show various different natural colours, but because flavonoid glycoside is typically soluble in water, so that
Aqueous white paint is caused easily to occur oozing yellow phenomenon.
In the prior art, in order to effectively prevent the moisture penetration in water-borne wood coating from entering timber, preparation has Waterborne wood
Device sealing paint, the aqueous wooden ware sealing paint is to obtain particle diameter by raw material of the acrylic monomer containing various polarity group
Small and narrowly distributing nanosize latex, and be obtained after adding various auxiliary agents as basic film forming matter with this nanosize latex, the water
Polar functional group in property woodwork coating on polymer molecular chain has good wetability to timber so that latex particle is easy
In penetrating into the fiber duct of timber, it is possible to the fast filming in pore, such that it is able to effectively prevent water-borne wood coating
In moisture in timber permeate, this can solve the problem that the surface gully problem that timber water-swellable is caused, it is also possible to Waterborne wood
The material that turpentine oil, tannic acid etc. easily exosmose in device sealing paint plays preferable sealing process.However, this kind of closure
Apply material list from the permeability of moisture set about still being difficult to solving bamboo and wood in flavonol water solubility problems.
