Problems solved by technology

[0003] Charging piles can quickly charge cars, and can also charge electric vehicles at night when electricity prices are low. Charging piles are generally placed outdoors and are easily corroded by air and water. However, the existing charging pile plates are waterproof and corrosion-resistant The performance is not good, which is more likely to lead to electric leakage and electric shock accidents. In addition, the temperature and weather resistance of the existing charging pile plates are not good. Because the charging piles are often exposed to sunlight, it is easy to cause the temperature of the charging piles to be too high. Cause internal electronic components to burn or lose performance

preparation example Construction

[0017] The invention discloses a charging pile sheet material and a preparation method thereof, comprising: 50-80% of continuous fibers, 20-40% of polyurethane resin, 0-15% of additives, and 1-10% of curing agent by weight percentage.

[0018] Described continuous fiber adopts one or both in basalt fiber, glass fiber, carbon fiber, and the form of described continuous fiber comprises long fiber, fiber mat or fiber woven cloth, and described additive is calcium carbonate, and described The curing agent is one of hexahydrophthalic anhydride and diacetone acrylamide.

[0019] The preparation steps of a charging pile plate according to the present invention are as follows:

[0020] Step 1: mix the polyurethane resin, additives and curing agent uniformly in the resin tank according to the above weight percentage to form a colloidal solution;

[0021] Step 2: Draw out the continuous fiber from the continuous fiber roll on the creel and unroll it, and then pass through the tension ...

Embodiment 1

[0025] Step 1: By weight percentage, 30% polyurethane resin, 5% calcium carbonate and 10% hexahydrophthalic anhydride are mixed uniformly in a resin tank to form a colloidal solution;

[0026] Step 2: Draw out 60% basalt fiber from the basalt fiber roll on the creel and unroll it, and then pass through the tension adjustment device and the preheating device in turn to obtain a preheated continuous fiber tape. The preheating temperature is 200°C;

[0027] Step 3: Add the colloid solution prepared in step 1 to the impregnation device and the impregnation calender roll group, pre-impregnate the preheated basalt fiber tape in the impregnation device, and guide the pre-impregnated basalt fiber tape into the impregnation calender roll group for Impregnation, the impregnation temperature is 200°C, and then cooled and shaped by the cooling roller pressing device, the cooling roller pressing pressure is 4 MPa, and finally imported into the traction and winding device for winding and for...

Abstract

The invention discloses a charging pile board and a preparation method thereof. The charging pile board comprises 50-80% of continuous filaments, 20-40% of polyurethane resin, 0-15% of additives, and 1-10% of a curing agent according to weight percentage. The continuous filament adopts one or two of a basalt fiber, a glass fiber and a carbon fiber, and is in the forms of long fiber, fiber mat and fiber woven fabric, the additive is calcium carbonate, and the curing agent is one of hexahydrophthalic anhydride and diacetone acrylamide. The charging pile board has the advantages of excellent corrosion resistance, weather fastness, waterproofness and the like.

Description

technical field [0001] The invention relates to a charging pile sheet material and a preparation method thereof, which are applied in the field of charging pile processing. Background technique [0002] With the national energy-saving emission reduction and low-carbon life, electric vehicles have been vigorously promoted. Electric vehicles are powered by vehicle-mounted power supplies and driven by motors. They do not emit carbon dioxide and have no tail gas pollution, which can effectively reduce environmental pollution. How to charge electric vehicles is an important issue, and charging piles can effectively solve the problem of difficult charging. [0003] Charging piles can quickly charge cars, and can also charge electric vehicles at night when electricity prices are low. Charging piles are generally placed outdoors and are easily corroded by air and water. However, the existing charging pile plates are waterproof and corrosion-resistant The performance is not good, ...
