油漆,特别是建筑用漆(油性调合漆)其基料需耗用大量食用植物油,如按每万平米建筑面积耗油漆3.5吨计算,其中就需耗用食用植物油1000公斤,按年竣工面积一百万平方米计算,就需耗用食用植物油100吨,可供十万人吃四个月。因此,推广不用食用植物油制成的新型建筑用漆有着深远的政治意义和经济意义。其次,用食用植物油制造的油漆,耐候性差,据实测,目前的油性调合漆在室外施工后,一般4～6个月就失光、粉化,开裂,失去对建筑物的应有的保护作用。
Paints, especially architectural paints (oily paints), require a large amount of edible vegetable oils for their base materials. For example, 3.5 tons of paint is consumed per 10,000 square meters of building area, and 1,000 kilograms of edible vegetable oil is needed. For one million square meters, 100 tons of edible vegetable oil will be consumed for four months. Therefore, it is of far-reaching political significance and economic significance to promote new types of architectural paints made without edible vegetable oils. Secondly, paints made from edible vegetable oils are poor in weather resistance. According to actual measurements, after the current oily blending paints are applied outdoors, they generally lose their light, powder, crack, and lose their proper protection for buildings within 4 to 6 months. effect.
