Description

A kind of MDF water-based anti-rise muscle white primer and preparation method thereof and application
Technical field
The present invention relates to a kind of medium density fibre board (MDF) water-based anti-rise muscle white primer and preparation method thereof and application, this priming paint can be used for the bottom application of medium density fibre board (MDF).
Background technology
The timber muscle that rises, or claim the wood grain projection, be common in an aqueous woodware paint application phenomenon; Its muscle mechanism that rises is: timber need cut in the course of processing with acute and cut, and can cut off or destroy the integrity of lumber fibre inevitably, when the fiber of timber comes out; Xylon will be as suction pipe; Suck moisture in the timber, cause lumber fibre to expand, be projected on wood surface.
And medium density fibre board (MDF) (calling MDF in the following text) is to be raw material with wood fibre or other vegetable fibre, through smash, fiber separation, dry back add the sizing agent that is suitable for, and passes through the artificial board that hot pressing forms again.Therefore the surface fiber of MDF all is in exposed state, adopts the water-miscible paint application, unavoidably the muscle phenomenon that rises can occur.
What with the MDF be that furniture, artwork or the Indoor decorative plate overwhelming majority of base material carry out is real look application; Its first road priming paint major part all is a white primer; Also have part to adopt transparent priming application or real color bottom paint application (removing white), the allotment of real color bottom paint mainly is to accomplish through transparent priming, white primer and mill base.Therefore the muscle that do not rise in the time of will guaranteeing should the reality color bottom paint to carry out the MDF application then needs transparent priming and white primer all to possess and prevents rising the muscle function.
Summary of the invention
In order to solve the muscle problem that rises that produces when MDF adopts existing water-miscible paint application; Primary and foremost purpose of the present invention is to provide a kind of MDF water-based the anti-muscle white primer that rises; This priming paint makes medium density fibre board (MDF) no matter be to carry out white primer application or real color bottom paint application, the generation of the muscle problem of all can avoiding rising.
Another object of the present invention is to provide the preparation method of the anti-muscle white primer that rises of above-mentioned MDF water-based.
A purpose more of the present invention is to provide the purposes of the anti-muscle white primer that rises of above-mentioned MDF water-based.
The object of the invention is realized through following technical proposals:
The anti-muscle white primer that rises of a kind of MDF water-based is prepared by following compositions in portion by weight:
Water-borne acrylic resin: 55-60 part
The anti-muscle resin that rises of water-based: 20-24 part

Grinding auxiliary agent: 0.5-1 part
Film coalescence aid: 2-2.5 part
Flow agent: 0.1-0.5 part
Skimmer: 0.3-0.4 part
Thickening material: 0.5-0.7 part
Water: 8-9 part;
The second-order transition temperature of said water-borne acrylic resin is-10-20 ℃, and solid content is 55%;
The anti-muscle resin that rises of described water-based is the Viscotrol C acrylated aliphatic urethane of self-crosslinking;
The acid number of described Viscotrol C acrylated aliphatic urethane is 220-270mgKOH/g, and molecular weight is 8000-19500g/mol, and second-order transition temperature Tg is 90-108 ℃;
Described white titanium pigment is a Rutile type Titanium Dioxide;
Described grinding auxiliary agent is Zinic stearas and/or calcium stearate;
Described film coalescence aid is butyleneglycol and/or alcohol ester-12;
Described flow agent is organic silicon modified by polyether oxygen alkane and/or fluorin modified crylic acid polymkeric substance, can adopt the commercially available prod, is the product of SA-100N like the Shanghai Jie Sen trade Co., Ltd trade mark;
Described skimmer is more than one in polyether modified siloxane, MO or the silicone oil;
Described thickening material is a Natvosol.
The preparation method of the anti-muscle white primer that rises of above-mentioned MDF water-based may further comprise the steps:
(1) with water-borne acrylic resin and the anti-muscle mixed with resin that rises of water-based, 400r/min adds entry under stirring, and mixes 15-20min;
(2) add white titanium pigment, grinding auxiliary agent, film coalescence aid, flow agent, skimmer more successively, 600r/min mixes 30-35min down;
(3) rotating speed is adjusted to 100r/min, adds thickening material and stir 5-10min, make the anti-muscle white primer that rises of MDF water-based.
The anti-muscle white primer that rises of above-mentioned MDF water-based can be used for the primer painting of medium density fiber slab products.
The anti-muscle white primer that rises of water-based medium density fibre board (MDF) of the present invention; High molecular polymer and special auxiliary agent by the nano level particle diameter are formed; This product has hypertonicity and closure, and can combine rapidly with wood fiber component rapidly, comparatively fast solidifies again; Therefore fiber can not expand or degrees of expansion weakens greatly, has improved in construction, the rise problem of muscle of water-miscible paint greatly.
The present invention has following advantage and effect with respect to prior art:
1, the anti-muscle white primer that rises of MDF water-based of the present invention adds an amount of flow agent in prescription does not have negative impact to the recoatability that descends one finish paint, and can obviously improve the levelling wettability of priming paint.
2, the anti-muscle white primer that rises of MDF water-based of the present invention when guaranteeing drying and polishing performance, can not produce the muscle phenomenon that rises when being coated on medium density fibre board (MDF); This priming paint water-based safety and environmental protection, and have closed performance efficiently.
3, the prime treatment of MDF only need spray the operation of the anti-muscle white primer that rises of MDF water-based of the present invention together, the muscle effect that rises of xylon just can not occur, has not merely saved operation, has more improved polishing personnel's efficient.
