Abstract

The invention discloses a preparation method of an epoxy zinc-rich primer with good anti-falling and anti-aging effects. The preparation method comprises the following steps: S1, preparing an epoxy zinc-rich primer component A: S101, proportionally mixing 600-mesh zinc powder and 500-mesh mica iron oxide to obtain zinc powder; S102, mixing dipropylene glycol butyl ether and diethylene glycol monobutyl ether to prepare a coalescing agent; S103, adding epoxy resin, a coalescing agent, a dispersing agent and a defoaming agent into the stirring container for mixing, adjusting the rotating speed to600-800 revolutions per minute, and stirring and mixing for 5 minutes at normal temperature; according to the preparation method of the epoxy zinc-rich primer with the good anti-falling and anti-aging effects, the epoxy zinc-rich primer with the good anti-falling and anti-aging effects is prepared by adjusting the proportions of the different raw materials and adopting the proportions of the different raw materials at the same time, and is high in adhesive force, capable of reflecting and absorbing ultraviolet rays, good in anti-falling effect and long in service life.

Description

technical field [0001] The invention relates to the technical field of epoxy, in particular to a preparation method of an epoxy zinc-rich primer with good anti-shedding and anti-aging effects. Background technique [0002] Metal corrosion is a very serious problem faced by modern people, and this problem covers almost all fields of social production. Due to corrosion, a large amount of hard-won useful materials become waste, resulting in weakened protection, equipment failure, consumption of resources and huge economic losses, and indirectly caused problems such as environmental pollution. For a long time, people have used many technologies to protect metals and prevent corrosion. One of the most effective methods is to coat the metal surface with an anti-corrosion coating to isolate the corrosive medium from the metal substrate. [0003] At present, epoxy zinc-rich primer is one of the most important metal anti-corrosion coatings. Since zinc is more active than iron, it i...
