Abstract

The invention discloses an epoxy zinc-aluminum pseudo-alloy cold-coating primer and a preparation method thereof, and belongs to the field of coatings. The epoxy zinc-aluminum pseudo-alloy cold-coating primer comprises a component I and a component II curing agent, wherein the component I comprises the following raw materials in percentage by mass: 15-23% of epoxy resin A, 0.2-1.5% of a dispersant, 3-5% of polyamide wax slurry, 10-35% of zinc powder, 8-27% of XY-110 non-floating aluminum powder, 5-40% of silica powder, 0.3-1% of an antifoaming agent, 0.5-1.5% of a silane coupling agent, 6-12%of xylene and 2-7% of butanol. The epoxy zinc-aluminum pseudo-alloy cold-coating primer provided by the invention is in a liquid construction state, can be directly brushed, roll-coated and sprayed atnormal temperature, is used for replacing a hot-dip galvanized (dipped) zinc-aluminum alloy anticorrosive coating in an existing ultra-long-term steel structure heavy-duty anticorrosive scheme, and has performance superior to that of an arc hot-dip galvanized aluminum alloy anticorrosive coating. And meanwhile, the consumption of the zinc and aluminum powder of the product is far lower than thatof a hot galvanizing aluminum layer (basically pure zinc and aluminum), so that the consumption of metal zinc and aluminum resources can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a novel material epoxy anticorrosion primer containing zinc and aluminum metal powder. Background technique [0002] Metal corrosion is a huge hazard, and there are many means of metal protection. At present, the most used and mature protection means are coating and plating protection. Coating protection is to spray a layer of anti-corrosion paint on the metal surface to shield the metal and prevent corrosion factors from contacting the metal substrate to form corrosion to protect the metal; coating protection is to uniformly heat-melt the metal that is more active than the substrate Covering the surface of the protected metal, due to the more active coating when corrosion occurs, the base material is protected by sacrificing itself anodically. The most widely used are hot-dip (dip) zinc and hot-dip (dip) zinc-aluminum protective layers. With the increasing awareness of nat...
