The inorganics that adds in order to ensure opacifying property that is comprised in the light-blocking agent for agricultural use of each embodiment provided by the invention can list lime carbonate, titanium oxide, titanium white, talcum, clay, silicon oxide, mica and barium sulfate etc.Wherein, especially preferably use lime carbonate or titanium oxide.In addition, also can as required the inorganics more than two kinds be mixed use.
About these inorganicss, in first embodiment of the present invention, two kinds of inorganicss that can median size is different mix use.
Particularly, when the difference of its particle diameter is benchmark with 1 μ m, can be that two kinds of inorganicss more than the 1 μ m are used in combination less than the inorganics of 1 μ m and median size with median size.The maximum value of median size is about 100 μ m.
Median size less than the inorganics of 1 μ m be coated on resin emulsion as wedding agent agricultural with the situation on the greenhouse film under, be distributed in the resin emulsion with the subparticle shape, thereby the firm inorganics of formation is filmed on film, can improve its water tolerance.But, but be difficult to remove when not required.
On the other hand, median size be the above inorganics of 1 μ m be coated on resin emulsion as wedding agent agricultural with the situation on the greenhouse film under, water tolerance is poor.
Therefore, in the present invention, use the two, can keep the balance of water tolerance and removing property by mixing.The inventor's result of study finds, in order to ensure as agricultural with the water tolerance of shading coating fluid and removing property, median size less than the inorganics of 1 μ m and median size be more than the 1 μ m inorganics than in 1: 0.5～2 scope for good.
That is, the ratio of mixture that is the inorganics more than the 1 μ m less than inorganics and the median size of 1 μ m when median size is less than 0.5 the time, and is insufficient with the water tolerance of shading coating fluid as agricultural, but surpassing at 2 o'clock, and water tolerance is abundant, but removing property deficiency.As the different inorganics of these median sizes, can select above-mentioned various inorganics, wherein preferably use lime carbonate or titanium oxide.
On the other hand, in the of the present invention second and the 3rd embodiment,, can be extensive use of from median size to being inorganics about 100 μ m to median size less than the inorganics of 1 μ m to the not special restriction of the particle diameter of inorganics.In addition, when median size be coated on resin emulsion less than the inorganics of 1 μ m as wedding agent agricultural with greenhouse film on the time, be dispersed in the resin with the subparticle shape, thereby on film, form firm inorganics film, can improve its water tolerance, but have the shortcoming of removing property difference when not required, still, if there are not the problems referred to above in second embodiment of the present invention and the 3rd embodiment when then using.
In addition, inorganics more than median size is 1 μ m with the resin emulsion as wedding agent be coated on agricultural with greenhouse film on the time, have the shortcoming of poor water resistance, still, if there are not the problems referred to above in second embodiment of the present invention and the 3rd embodiment when then using.Certainly, in second embodiment and the 3rd embodiment, also can use the opalizer of first embodiment.
