Dispersion liquid and silane coupling agent mix to form a kind of light (referring in particular to following preparation method) in some way
The sub- transparent high definition imaging agent of crystallite.
Adhesive is the carrier of the transparent high definition imaging agent of photon crystallite, plays the role of suspended nano photon microcrystal and makes
The transparent high definition imaging agent of nano-photon crystallite is bonded in the effect of transparent material dielectric surface, and in the technical program, adhesive is excellent
It is selected as water-soluble binder, common are water-soluble acrylic lotion or soluble polyurethane lotion, but the present embodiment is not limited to
This two kinds of adhesives.
The effect of silane coupling agent is the rapid on different transparent material surfaces of the increase transparent high definition imaging agent of photon crystallite
Drawout and cured ability, silane coupling agent is silane coupled using the KH-550 of the excellent general chemical industry in Nanjing in the present embodiment
Agent.
For the present embodiment in more preferably technical solution, the transparent high definition imaging agent of photon crystallite also includes levelling agent, levelling agent
Accounting for weight ratio is 0.1-0.3.In the case where adding levelling agent, the transparent high definition imaging agent of photon crystallite applies in coating or spraying
The more uniform levelling of layer meeting, can reach ideal planarization effects.Levelling agent is using Beijing An Taigeke in the present embodiment
140 levelling agent of Hydropalat of skill Development Co., Ltd.
For the present embodiment in more preferably technical solution, the transparent high definition imaging agent of photon crystallite can also include defoaming agent,
It is 0.05-0.2 that defoaming agent, which accounts for weight ratio, for eliminating in the transparent high definition imaging agent preparation process of photon crystallite and application process
The bubble of middle generation.Defoaming agent is using OS-5201 defoaming agent common on the market in the present embodiment.
The present embodiment 1 is a kind of transparent high definition imaging agent of photon crystallite, and imaging agent includes nano-photon microcrystal, can be made
After any transparent material coating or spraying go up it, become the throwing of the high grade of transparency, high brightness, high contrast and high color saturation
Shadow screen, and this projection screen be it is transparent, can be used as transparent metope etc. when not used.
