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] FRP is a material with certain mechanical strength, excellent corrosion resistance, light weight and low price. At present, it is widely used to manufacture photovoltaic brackets. However, the existing FRP has been exposed to the atmosphere for more than one year, and its appearance changes significantly, and its color will change. Yellow, brittle and cracked, the surface loses luster, the strength decreases, and other physical and chemical properties decrease accordingly

Embodiment 1 2

[0020] The preparation of embodiment 1 titanium dioxide modified attapulgite

[0021] 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;

[0022] 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 and then calcined and ground to obtain a titanium dioxide-attapulgite composite;

[0023] 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.

Embodiment 2

[0025] A high-toughness and weather-resistant glass fiber reinforced plastic photovoltaic bracket, which is composed of the following raw materials in parts by weight: 100 parts of epoxy resin E44, 1 part of dibenzoyl peroxide, 1 part of methyl ethyl ketone peroxide, 2.5 parts of zinc stearate, and lead stearate 1.5 parts, 20 parts of calcium carbonate, 23 parts of titanium dioxide modified attapulgite.

Embodiment 3

[0027] A high-toughness and weather-resistant glass fiber reinforced plastic photovoltaic bracket, which is composed of the following raw materials in parts by weight: 120 parts of epoxy resin E44, 1 part of dibenzoyl peroxide, 3 parts of methyl ethyl ketone peroxide, 2.5 parts of zinc stearate, and lead stearate 2 parts, calcium carbonate 25 parts, titanium dioxide modified attapulgite 30 parts.
