Description
Technical field
The present invention relates to timber priming paint technical field, specifically a kind of impervious color aqueous wooden ware seal coat.
Background technology
In recent years, the environment-friendly advantage that water-borne wood coating is protruded by it, health and security, become the one of woodwork coating
Developing direction.Aqueous woodware paint is a kind of special dispersion using water as decentralized medium, is being coated on water-wet behavior
During wood surface, moisture is easily infiltrated through in timber, and is contacted with the water-soluble coloring matter in timber.These coloring matter meetings
It is dissolved in the water, is slowly spread then as paint film drying process, and finally migrate to coating surface, forms yellow or brown
Color spot deepens whole paint film color flavescence.In addition, from the point of view of aqueous woodware paint membrane formation mechanism, polymer is with spheric granules point
Dissipate in water.In paint film drying process, with moisture evaporation a series of physical chemical process occurs for these particles：Granulation mass
Product, molten bonding, the diffusion of the polymer end of the chain etc., and ultimately form a continuous paint film.Therefore coating initial is not fine and close, ball
Between shape particle will necessarily there are gap, be in timber pigment on ooze and provide passage, therefore, water-borne wood coating application
, often there is bleeding problem in Cheng Zhong, influences paint film apparent property.
Mainly had using more impervious color method at present：Base material is pre-processed, and use has impervious color energy
The seal coat of power.Wherein, the use of impervious color bottom paint is a kind of important impervious color method.As US6245141B1 discloses one
The water-based anti-tannic acid bleeding coating of kind addition titanate coupling agent (titanatecouplingagent).The titanate esters are coupled
Agent at least contains an amino reactive group, may be added to that in resin, pigment, or is added to after pigment dispersion in system, addition
Amount is about the 0.1%-2% of color stuffing quality, and it is LICA44 to use additive.CN102417774A discloses a kind of containing changing
Property barium metaborate Water-based white sealed primer and preparation method thereof, which has closing timber tannic acid
Performance, can persistently play closing well and make after constructing on containing tannic acid, nicotine spot and base material containing water-based pigment
With, covering painting aqueous white woodwork coating again above will not be changed colour by above-mentioned contaminants, and with good grinability, screening
Lid power and antiseptic property, can prevent decay of wood from going bad.
But the prior art has the following disadvantages：(1) most technical solutions using be used alone impervious color auxiliary agent or sun from
Seal coat is made in sub- lotion, but is although individually to prevent that all kinds are coloured using seal coat made from cation emulsion
The comprehensive best scheme of material exudation, but its main bleeding material this kind of to tannic acid on the more serious timber of bleeding
Sealing ability is still limited.(2) combined between most formula moderate resistance bleeding auxiliary agents and impervious color lotion without preferable, both are mutual
Effect is easy to the bin stability of influence system, therefore the realization of coating resistance to bleed energy still has the space that can be enriched.(3) it is straight
Connect the solution that application is carried out using the water-based white paint with impervious color ability.Although some face with impervious color ability are filled out
Material can be used for improving resistance to bleed energy in water-based white paint.But due to the influence of solid color enamel system color stuffing, its paint film is caused to cause
Close property is poorer than varnish system, therefore the sealing effect of tannic acid can also have been declined.
