TiO2-containing flat solar Al alloy plating and preparation method thereof

The invention discloses TiO2-containing flat solar Al alloy plating and a preparation method thereof. A plating material is prepared from raw materials in percentage by mass as follows: 0.8%-1.6% of TiO2, 0.8%-1.0% of Si, 1.0%-2.0% of Fe, 10%-20% of Zn, 0.2%-0.5% of Pr, 0.2%-0.3% of Re and the balance of Al. The preparation method of the plating material is simple, and the plating material is wellbonded to a matrix and is not prone to falling; the prepared Al alloy plating is attractive, good in corrosion resistance, good in abrasion resistance, high in strength, high in ductility and high inheat absorption and heat transfer capacity. 本发明公开了种含TiO的平板太阳能铝合金镀层及其制备方法，镀层材料由以下质量比例的原料制得：0.8～1.6%TiO、0.8～1.0%Si、1.0～2.0%Fe、10～20%Zn、0.2～0.5%Pr、0.2～0.3%Re，余量为铝。本发明镀层材料制备方法简单，与基体结合好，不易脱落；制备的铝合金镀层美观，耐腐蚀性和耐磨性好，强度和延展性高，吸热传热能力强。
