At least one in ketone；
Described surface control agent is polyacrylate, homopolymerization bonding copolymer, and molecular weight is between 500-10000g/mol.
A kind of weatherability exterior wall ultraviolet light polymerization of the present invention（UV）Coating, it is as follows that it is specifically made step：
The first step, heating mixing：Raw material is mixed in proportion, in pot arch, high temperature fusion is carried out, temperature control 70 DEG C-
90 DEG C, the time was at 3-5 hours；
Second step, decentralized processing：The first step is obtained into product, stirring in homogenizer is added to, temperature control is in normal temperature.
First by bond energy chemical bond high such as Si-C, F-C keys are introduced into resin the present invention, and reduce C=C double bonds in coating
Density, the so overall chemical bond of the resin of synthesis is very firm, and key is more firm, and molecule is more stable, and weatherability is better, by chemistry
The resin dispersion of key stabilization adds initiator and granule surface contral auxiliary agent in the monomer of fluorine richness, by after the dispersion of physics
It is made photocureable coating.
The present invention has an advantageous effect in that compared with prior art：
