Infusion, levelling agent input material cylinder, continuously stir mixing 10 minutes under 400~600r/min rotating speed;
2) nertralizer, curing agent are added under 800~1000r/min rotating speed, continuously stirs mixing 20 minutes;
3) white carbon, heat discoloration pigment are put under 1000~1200r/min rotating speed, thickener, is continuously stirred mixed
It is bonded to few 30 minutes and adjusts viscosity to 150pa.s;
4) remaining deionized water, mill base needed for input formula under 400~600r/min rotating speed, reduction viscosity to 80~
120pa.s, and filtered after continuously stirring mixing 20 minutes.
The present invention has advantages below compared with prior art:
1st, the present invention is coordinated using finish paint with priming paint, because finish paint and primed surface tension force are different with drying shrinkage factor, first
Priming paint brush finish again after its drying is brushed, finish paint can gradually be ftractureed in its drying process and the upper amplitude limit that ftractures
Height, its crackle degree can be obtained adhesive force well and lines cracking are regular, attractive in appearance by brushing thickness control after its drying
Crack effect, it is and simple to operate, easy for construction.
2nd, heat discoloration pigment used herein is a kind of organic compound of microcapsule structure, in different temperatures section
Its interior internal organic compound can change with temperature and produce certain receiving and losing electrons phenomenon, and then produce color change.Utilize this
One characteristic, using the pigment (such as 28 degree of sky blue bleach, 40 degree of dark blue bleach) in two or more different temperature-sensitive sections as water
Property environmental protection heat discoloration crackle paint part simultaneously coordinates the aqueous color paste of certain deal, is fabricated to water-based heat discoloration environmental protection and splits
Line finish paint, can be with change (such as zubzero temperature~28 DEG C, 28 DEG C~40 DEG C, more than 40 DEG C) production of the ambient temperature in different sections
Add lustre to phase, the depth or light and shade it is different change, it is to be dried after its brushing manufactured goods can vary with temperature and produce respective change.
3rd, each component employed in the present invention is aqueous environment protection material, and unharmful substance volatilization will not be to using
Person's body and environment cause any harmful effect.
