Abstract

The invention provides a reaction system for continuously and rapidly preparing antiglare liquid, which comprises a material storage tank, an impingement flow static mixer, a microwave reactor, a Venturi static mixer, a cooler and a constant flow pump. Using this reaction system to prepare the anti-glare liquid, the silicate, alcohol, water and catalyst acid are quickly and uniformly mixed through the impingement flow static mixer, and the mixed material flows through the microwave reactor and is rapidly heated to further accelerate the hydrolysis reaction At the same time, a large amount of hydrolyzed silanol is condensed into a small-sized polycondensate; then it is quickly mixed with a blocking agent when flowing through the Venturi static mixer, and the addition of the blocking agent blocks the further progress of the silanol condensation reaction and the polycondensate growth; and then through the rapid cooling of the cooler, the reaction speed is further reduced, and a highly stable anti-glare liquid is obtained. The solution of the invention has simple process, strong controllability, stable product performance, easy mass production, low energy consumption, and has strong industrialization conditions and prospects.
