Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of high efficiency, low cost lotus leaf lacquer and preparation method thereof.
Background technology
The lotus leaf lacquer has the same remarkable hydrophobic effect of lotus leaf, preeminent stain resistance, outstanding respiration, green environment-friendly function, so claim " lotus leaf lacquer " again.It has following characteristics:
A, has outstanding water proof and dust proof characteristic, the hydrophobic nature of height;
B, perfect protective value are particularly for enduring the exposure metope that ugly weather exposes to wind and rain to the fullest extent;
C, reduce the sticking power of contamination particle, automatically cleane metope to greatest extent.
Lotus leaf lacquer and common lacquer are very easy to find after relatively: spill water on lotus leaf lacquer model surface, the globule can be assembled automatically, and it is dry and comfortable that paint film keeps, and generic latex lacquer model moisture content is easy to infiltrate into paint film inside, and coating surface is moist.This is because lotus leaf lacquer coating surface has the hydrophobic nature of height, makes paint film produce the effect that similar lotus leaf plays the globule, effectively prevents the moisture content infiltration, can keep paint film dry and comfortable for a long time.The hydrophobic nature of height also makes metope that the self-cleaning function of similar lotus leaf is arranged, and reduces the sticking power of dust granule to greatest extent, reaches the effect of automatically cleane metope.
