Abstract

The invention provides a graphene polymer composite organic coating which is mainly prepared from the following components in parts by weight: 40-60 parts of base resin, 1-1.5 parts of graphene, 30-55 parts of composite modifier and 20-45 parts of curing agent, wherein the base resin comprises phenol-formaldehyde resin and bisphenol F in a weight ratio of (1:2)-(1:4). The invention also provides a preparation method of the composite organic coating. The preparation method comprises the following steps: heating the phenol-formaldehyde resin, stirring and adding the bisphenol F resin; adding an antifoaming agent; adding graphene, stirring and dropwise adding a pretreating agent; adding polytetrafluoroethylene powder, silicon dioxide hollow spheres, mica powder, talc powder, a leveling agent and nano silicon; adding an ultraviolet absorbent and an antioxidant while keeping the system temperature below 60 DEG C to obtain modified resin; and mixing the modified resin with the curing agent and stirring to obtain the composite organic coating. The invention also provides an application of the organic coating.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a graphene polymer energy-saving and environment-friendly composite material coating and its preparation process and application. Background technique [0002] Pumps are general-purpose machinery that are widely used. Whether it is in the military industry, nuclear power, industry, or civilian fields, pumps are almost always working wherever there is liquid flow. The pump is also a large energy consumer. The electricity consumption of the pump is about 25-27% of the country's total power generation, and the fuel consumption is 6-8% of the country's total fuel consumption. The motor with about 45% capacity is used to drive the pump. [0003] However, in reality, due to the restriction of the pump manufacturing process level, the efficiency of the pump is generally low; at the same time, due to the influence of the use environment (such as various corrosion, cavitation, abrasion, e...
