CN105585944A - Unsaturated polyester white undercoat - Google Patents

Abstract

The invention relates to the field of woodware paints and especially provides an unsaturated polyester white undercoat and a preparation method thereof. The undercoat can be widely used on objects such as office furniture, suites for adults and children, woodware and the like. The unsaturated polyester white undercoat breaks the limit in conventional formula, wherein a CAB liquid is added to the undercoat. The CAB liquid belongs to a kind of cellulose, so that the undercoat prepared therewith can prevent paint film from cracking on furniture being complex in carving technologies. The undercoat is high in drying speed, is good in rubbing property, and can effectively increase the utilization rate of woodware furniture. The undercoat can replace common oily paints completely, thereby reducing environment pollution and showing the effect of a complex carving technology better. The unsaturated polyester white undercoat includes the following main materials: resin, a flatting agent, a dispersing agent, a defoamer, an anti-settling agent, talcum powder, zinc powder, titanium dioxide, styrene, and the CAB liquid which belongs to a kind of cellulose.

Description

Unsaturated polyester (UP) based white primer

Technical field: the present invention relates to woodwork coating field, especially unsaturated polyester (UP) based white primerAnd preparation technology, it can be widely used in the things such as office furniture, adult children suite, woodworkPart.

Background technology: at present, the woodenware based white primer on market is used in artistic carving more complicatedOn furniture, there is a lot of defects. Mainly in furniture surface configuration more complicated, concavo-convex angleLarger place easily produces the situation of paint film cracking. Reason is mainly in furniture surface configurationComplexity, in the larger situation of concavo-convex angle, coating surface insufficient strength is large, causes paint film partDistortion produces the phenomenon of cracking.

Summary of the invention: the shortcoming existing for above-mentioned prior art, inventor's accumulation for many years fromThe experience of thing this area work, through feasibility study repeatedly, obtains generation of the present invention eventually, thisBrightly provide a kind of unsaturated polyester (UP) based white primer, solve prior art in furniture surface configuration complexity,In the larger situation of concavo-convex angle, coating surface insufficient strength is large, causes paint film local deformation to be producedThe defect of raw cracking phenomena.

The technical solution used in the present invention: for achieving the above object, the invention provides a kind of insatiable hungerWith polyester based white primer, it is mainly prepared burden and is: resin, levelling agent, dispersant, defoamer, anti-Heavy agent, talcum powder, zinc powder, titanium dioxide, styrene, CAB liquid, described each batching is notThe mass percent of saturated polyester based white primer is:

Resin: 35%～45%

Levelling agent: 0.～0.3%

Dispersant: 03%～0.6%

Defoamer: 0～0.4%

Anti-settling agent: 04%～0.7%

Talcum powder: 33%～37%

Zinc powder: 2%～4%

Titanium dioxide: 8%～12%

Styrene: 2%～3%

CAB liquid: 3%～6%

For achieving the above object, patent of the present invention has also proposed a kind of unsaturated polyester (UP) based white primerPreparation technology.

Above-mentioned unsaturated polyester (UP) based white primer step of preparation process is as follows:

The first step: first add the PE resin of 35%～45% part, agitator state is for slowly stirringMix;

Second step: the stream that simultaneously adds 0.～0.3% part in the situation that of slow agitating resinFlat agent, the dispersant of 0.3%～0.6% part, the defoamer of 0.～0.4% part stir 5 pointsClock;

The 3rd step: stir after 5 minutes, add 0.40Z0～0.7% part anti-settling agent part 8%～12% titanium dioxide, simultaneously high speed dispersion 5 minutes;

The 4th step: high speed dispersion adds the talcum powder and 2% of 33%～37% part again after 5 minutesThe zinc powder of～4% part, simultaneously high speed dispersion 15 minutes;

The 5th step: add the styrene of 2%～3% part and 3%～6% part after stiffness is qualifiedCAB liquid, stirring can discharging packaging after equal Uniform.

The beneficial effect of patent of the present invention: unsaturated polyester (UP) based white primer of the present invention has been broken tradition and joinedSide, has added a kind of CAB liquid, and described CAB liquid is a kind of cellulose, by its systemThe unsaturated polyester (UP) based white primer becoming can prevent paint film cracking on the furniture of artistic carving complexityPhenomenon, and rate of drying of the present invention is fast, and grinability is good, can effectively improve woodwork furnitureUtilization rate. Thoroughly replace conventional oil paint, reduce environmental pollution, better embody carverThe appearance effect of skill complexity.

Detailed description of the invention

Unsaturated polyester (UP) based white primer of the present invention, it is mainly prepared burden and is: resin, levelling agent, dispersionAgent, defoamer, anti-settling agent, talcum powder, zinc powder, titanium dioxide, styrene, CAB liquid,Described CAB liquid is a kind of cellulose.

This unsaturated polyester (UP) based white primer side of preparation processing step is as follows: the normal temperature more than 5 DEG C,Under clean dustless environment, carry out.

The first step: first add the PE resin of 35%～45% part, agitator state is for slowly stirringMix;

Second step: the levelling that simultaneously adds 0.～0.3% part in the situation that of slow agitating resinAgent, the dispersant of 0.3%～0.6% part, the defoamer of 0.～0.4% part stir 5 minutes;

The 3rd step: stir the anti-settling agent part that adds 0.40Z0～0.7% part after 5 minutes8%～12% titanium dioxide, simultaneously high speed dispersion 5 minutes;

The 4th step: high speed dispersion adds the talcum powder and 2% of 33%～37% part again after 5 minutesThe zinc powder of～4% part, simultaneously high speed dispersion 15 minutes;

The 5th step: add the styrene of 2%～3% part and 3%～6% part after stiffness is qualifiedCAB liquid, stirring can discharging packaging after equal Uniform.

In sum, be preferred embodiment of the present invention, allly do according to technical solution of the present inventionChange, when the function producing fails to exceed the scope of technical solution of the present invention, all belong toIn protection scope of the present invention.
