水性节能隔热混凝土彩瓦涂料的研制

以丙烯酸乳液为基料,填充硼改性中空陶瓷微珠和红外辐射材料,并添加其它适宜的颜填料、助剂等,制备水性节能隔热彩瓦涂料。通过硼改性中空陶瓷微珠的热反射作用以及红外辐射材料的幅射致冷作用,赋予该涂料优异的隔热性能。与普通混凝土彩瓦涂料相比,在光辐射强度为954W/m2时,被涂覆试件比未涂覆试件的温度低14℃;同时,通过对涂料配方的合理设计,使该涂料还具有优良的耐老化性及综合性能。

Aquosity concrete encaustic tile paint with energy saving and thermal insulation is prepared by taking polyacrylic emulsion as base material,filling boron modified hollow ceramic micro-sphere and infrared radiation material,and adding other proper accessory ingredients etc.The paint has excellent thermal insulation by heat reflection of boron modified hollow ceramic micro-sphere and radiation cooling of infrared radiation material.Compared with common concrete encaustic tile paint,temperature difference at the rear face of painted test piece is up to 14 ℃ when optical radiation intensity is 954 W/m2.The paint also has good weather resistance and comprehensive performance by rational design of paint formula.
