Abstract: The white control coatings with low ratios of solar absorptance to emittance are successfully prepared.The factors (resin type,filler type,ratio of resin to pigment etc.) that affect the property are discussed.The results indicate that coatings made with addition type rubber has lower α s value (<0 20).Increasing ratio of filler to adhesives value,the α s/ ε h value will decrease.In order to made low α s/ ε h value,the more content filler should be added into adhesive without giving up the art.The ratio of [Si H] to [CH=CH 2] has no obvious effect on α s value.But the type of vinyl silicone rubber has effect on α s value.The coating made with higher content vinyl group silicone rubber has larger α s value.For both of spraying and brushing method,brushing is preferred way although coatings made with them has similar α s value.
