“晒不热”建筑涂料的节能实效

Energy Saving Effect of “Insolating not hot” Building Coating

摘要:

采用价格低廉的低吸收率、高发射率碱土金属碳酸盐材料作为涂料填料，制备了“晒不热”建筑涂料.于海南的试验结果表明，彩钢瓦楞板屋顶涂刷该涂料后，其日间曝晒下室内温度比未涂者可低10 ℃，比涂市售同类涂料者可低2 ℃；空调设置温度为24 ℃时，涂该涂料的房间1昼夜比未涂者可节电1.72 kWh，比涂市售同类涂料者可节电0.81 kWh；空调设置温度为26 ℃及以上时，涂该涂料的房间比未涂者节电率大于40%，比涂市售同类涂料者节电率高15.6～20.8个百分点.

Abstract:

Insolating not hot coating is made out by using a cheap alkaline earth carbonates material with low solar absorptance and high emittance as filler of coating. The results of experiments in Hainan province indicate that the indoor temperature of the experimental house painted with the insolating not hot coating on the color steel corrugated sheet roof is 2 ℃ lower than that painted with a heat reflecting coating from market on the same roof, and 10 ℃ lower than that painted with nothing on the same roof. When air conditioning temperatures of three experimental houses are all set to 24 ℃, the 24 h electricity consumption of the house painted with the insolating not hot coating is 1.72 kWh lower than that painted with nothing, and 0.81 kWh lower than that painted with the heat reflecting coating from market. When air conditioning temperatures of experimental houses are all set to not less than 26 ℃, the electricity saving rates of the house painted with the insolating not hot coating are 40% higher than that painted with nothing, and higher than that painted with the heat reflectting coating from marke by 15.6~20.8 percents.
