Abstract

The invention discloses a super-hydrophobic paint for old pump transformation and preparation method of the paint and belongs to the field of super-hydrophobic paints. The paint comprises a componentA and a component B. The component A is a modified resin composition and comprises 6-8 parts of epoxy resin, 0.6-0.7 part of active silica micro-powder, 0.8-0.9 part of active graphene micro-powder, 0.2-0.5 part of nano-zinc oxide, 2-3 parts of active aluminium oxide, 2-3 parts of active iron powder, 0.1-0.5 part of a heat-resisting agent, 0.6-0.8 part of a toughening agent and 0.6-1 part of an accelerant; the component B is a modified curing agent composition and comprises 6.5-8.5 parts of lauryl toluenediamine, 1.5-1.8 parts of aluminium oxide, 1.2-1.8 parts of tungsten carbide and 0.5-1.5 parts of silicon carbide. The surface of an old pump is coated with the super-hydrophobic paint to form a super-hydrophobic coating, so that the super-hydrophobic paint has a super-hydrophobic function, the friction resistance is lowered, the influence of the cavitation phenomenon on the pump body is reduced, and the energy-saving efficiency of the pump body is greatly improved.

Description

technical field [0001] The invention relates to the field of superhydrophobic coatings, in particular to a superhydrophobic coating for retrofitting old pumps and a preparation method thereof. Background technique [0002] With the development of industrial technology, pumps are used as transmission devices in a huge amount. According to statistics, all pump body series products consume nearly 20% of the world's electric energy, and pump energy consumption (electric energy consumption) accounts for 95% of the use cost. It is difficult to solve the problem of high electricity cost for enterprises. The cost of replacing spare parts of the pump accounts for 4% of its use cost. It seems that the cost is not high, but due to poor water quality, severe corrosion and cavitation, and fast calcification, the efficiency of the pump will decrease / stop running and other reasons. estimated loss. During the working process of the water pump, various losses will occur in the pump. The sm...
