一种隔热涂料及其制备方法
摘要：
本发明的隔热涂层使用具有级配的普通钛白粉和纳米二氧化钛的混合粉末作为颜料，配以高反射率和低导热率的填料，以水性丙烯酸溶液为粘结剂，制备出一种隔热性能优异的涂层。该制备方法为：首先将涂料的各个组分按照上述的配比进行称量和配料；然后在丙烯酸乳液中加入普通钛白粉、纳米二氧化钛、润湿剂、分散剂和消泡剂，在室温下用研磨分散搅拌机以1000r/min的速度下进行研磨分散；混合均匀后再加入空心微珠、滑石粉、增稠剂和成膜助剂以200r/min的速度搅拌，得到隔热涂料。具有紧密堆积效应，提高涂层分散性和均匀性，同时可以反射不同波段的光，提高了涂层的隔热性能。涂刷在基材表面，能减少内部温度的升高，并且节约成本。
摘要（英）：

A heat insulation coating with excellent heat insulation property is prepared from mixed powder of graded general titanium dioxide powder and nano titanium dioxide as pigment, fillers with high reflective rate and low conductive rate, and a waterborne acrylic solution as a bonder. A preparation method for the heat insulation coating comprises the following steps: firstly, weighing and proportioning components of the coating according to a ratio; secondly, adding general titanium dioxide powder, nano titanium dioxide, a wetter, a dispersant and a defoamer into acrylic emulsion, and performing grinding and dispersing at a speed of 1,000 r/min by a grinding and dispersing mixer at a room temperate; secondly, mixing uniformly, adding hollow microspheres, talcum powder, a thickener and a film-forming aid, and stirring at a speed of 200 r/min to obtain the heat insulation coating. The heat insulating coating has a dense-packing effect, so that the dispersity and uniformity of the coating are improved; meanwhile, the heat insulation coating can reflect light different in wavebands, so that the heat insulation property of the coating is improved. The surface of a base material is brushed with the heat insulation coating, so that the internal temperature rise can be reduced and the cost can be saved.
