The invention belongs to the field of waterproof materials, and discloses an ultrahigh weather-resistant layer, a TPO waterproof coiled material and a preparation method of the TPO waterproof coiled material. The material of the ultra-high weather-resistant layer comprises the following components: polyester resin, an auxiliary agent, titanium dioxide and a filler; the acid value of the polyester resin is 30 to 40 mg KOH/g, the softening point is 100 to 115 DEG C, the resin viscosity is 3200 to 4000 mPa.s, and the glass transition temperature is 50 to 65 DEG C. The invention provides the ultrahigh weather-resistant layer with excellent weather resistance, so that higher weather resistance can be provided for the waterproof coiled material, and the service life of the waterproof coiled material is prolonged. 本发明属于防水材料领域，公开了一种超高耐候层和TPO防水卷材及制备方法。所述超高耐候层的材料包括如下组分：聚酯树脂、助剂、钛白粉和填料；所述聚酯树脂的酸值为30-40mg KOH/g，软化点为100-115℃，树脂黏度为3200-4000mPa·s，玻璃化温度为50-65℃。本发明提供了一种耐候性能优异的超高耐候层，可为防水卷材提供更强的耐候性，提高防水卷材的使用年限。
