In each embodiment of table 2, easily matting resin is the weight mixtures such as modified epoxy acrylate resin and polyester acrylic, defoamer is the molar mixtures such as BYK055 and YK080A, dispersion agent is high molecular weight block copolymer, and the flatting silica of yellow phase is delustring wax, and wax powder is polyethylene wax, initiator is bitter almond oil camphor, flow agent is acrylate copolymer, and anti-settling agent is the polycarboxylate eka-silicon of polyamine acid amides, and monomer is modification acrylate.

Note: the passing through of outward appearance estimate to judge, the inspecting standard of sticking power is with reference to EN ISO 2409; The inspecting standard of glossiness is with reference to GB/T9754-1998; The inspecting standard of wear resisting property is with reference to GB/T18103-2000.

As can be seen from the above table, finish paint of the present invention has excellent surface property, and meanwhile, outward appearance, feel are better than prior art.

The present invention adopts easy matting resin, easily matting resin is to select the slightly slow resin of some speed of response, and connect the poor group of some consistencies, in the time solidifying, increase the diffuse-reflectance of light, reach the object of easy delustring, the consumption of flatting silica be can reduce like this, the transparency of paint film and the moist sense of paint film improved.Easy matting resin of the present invention, for example polyurethane acrylic resin and modified epoxy acrylate resin form micro-sphere structure in the time of film forming, make the unrestrained transmitting of incident light from delustring.Its reason is that Intermolecular Forces is inhomogeneous, thus crystallization rate formation different from degree micro-sphere structure in film process.

Simultaneously, most flatting silicas is all blue phase in paint film at present, be coated on behind floor, resemble and on floor, have one deck vaporific, affected the sharpness of paint film, the present invention has selected the flatting silica with yellow phase, flatting silica with yellow phase and most floor color approach, and more can show the natural character on floor, and it is high that flatting silica of the present invention has extinction efficiency, the advantages such as oil number is little, and feel is fine and smooth.

In addition, the wax powder transparency of the present invention is good, fusing point is 90 DEG C of left and right, and wax fusing point is more on the low side, and hardness can be on the low side, and feel can be soft; The wax powder surface tension of fluorine modification is low, can be more fine and smooth.

For monomer, functional group's number number represent the atom of chemical property that it determines organic compound or atomic group number, functional group more at most speed of response when physical reaction is faster, otherwise slower.Adopt the esters of acrylic acid of two functional groups or simple function group, or modification acrylate class, can reduce speed of response, make material be easy to delustring.

In a word, compared with prior art, lacquer painting exquisiteness of the present invention, good, the strong operability of the transparency, can better show the texture of timber.

More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.

It should be noted that in addition each the concrete technical characterictic described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible array modes.
