Problems solved by technology

[0002] At present, the accessories of photovoltaic brackets in the domestic market are mainly divided into two kinds of accessories made of galvanized steel and aluminum alloy. The section steel is heavy, inconvenient to transport and install, and easy to corrode; aluminum alloy brackets are generally used in the solar energy application on the roof of civil buildings. , aluminum alloy has the characteristics of corrosion resistance, light weight, beautiful and durable, but its bearing capacity is low
[0003] At present, people are more inclined to use plastic photovoltaic brackets. The biggest advantage lies in its low production cost and inexhaustible raw material reserves. This photovoltaic bracket can not only be bent, but also transparent in color, and can be fully integrated with windows and blinds without damage. The exterior wall and the appearance of the building, but the existing toughness and weather resistance need to be improved

Embodiment 1 2

[0021] The preparation of embodiment 1 titanium dioxide-attapulgite composite

[0022] 1) Disperse attapulgite with a mesh number of 800-1000 into 38 wt% hydrochloric acid solution under ultrasonic conditions, reflux in a water bath at 100°C for 16 hours, filter, wash until neutral and dry to obtain purified attapulgite for later use;

[0023] 2) Stir 100 g of the purified attapulgite evenly, then add 1 L of tetrabutyl titanate, 12 L of ethanol, 10 L of acetylacetone, and 12 L of deionized water, stir and react at room temperature to obtain a sol and then turn it into a gel. The obtained gel is dried, calcined and ground to obtain titanium dioxide modified attapulgite.

[0024] 3) Add 10 g of silicone oil to the obtained titanium dioxide-attapulgite composite by spraying, stir evenly, then add 5 g of silane coupling agent under high-speed stirring at 1500-2000 r / min, and mix evenly.
