Abstract
The invention discloses a polyurethane modified epoxy resin wear resistant paint. The polyurethane modified epoxy resin wear resistant paint comprises following raw materials, by weight, 10 to 20 parts of graphite, 5 to 15 parts of molybdenum disulfide, 5 to 10 parts of aluminium oxide, 2 to 6 parts of xylene, 2 to 6 parts of polyurethane modified epoxy resin, 2 to 6 parts of a curing agent, 12 to 15 parts of a bonding agent, 1 to 4 parts of an auxiliary agent and 15 to 20 parts of purified water.
Description
Technical field
The present invention relates to a kind of new coating and preparation method thereof, more particularly, relate to a kind of polyurethane modified epoxy resin wearresistant coatings.
Background technology
The result that inshore fishery mechanical erosion situation is investigated shows, due to fishing machine work under bad environment, and seriously corroded, the corrosion of wherein hanging oar is particularly outstanding.Extension oar is small Fishing Boat, diesel engine or other power-actuated small propeller for yacht afterbody, the wearing and tearing that the particles such as the hydraulicefficiency machinery that caused while rotating by sea-water corrosion, blade washes away, sand grains cause, require research to have the coating of excellent wear and corrosion behavior.
State's hanging outdoor unit paddle size is less, and rotating speed is up to 550 r/m in, and blade adopts aluminium alloy or stainless steel, and surface is comprised of prime coat, anti-zinc enamel paint layer and wear-resistant coating, and blade matrix is shielded.Domestic extension oar adopts cast iron cast aluminium material more, with red iron oxide alkyd primer and lacquer finish, makes surface decoration, and wear and corrosion behavior is poor, limited to the provide protection of blade.
Raw lacquer You Cheng state paint, has the performances such as excellent corrosion-resistant, insulation, oil resistant, wear-resisting, durable and high gloss, and we adopt modified raw lacquer is that base-material carries out the research of wear-and corrosion-resistant coating.There are 17 kinds of modified raw lacquer standardized products in China at present, and in order to improve the wear resistance of modified raw lacquer, first the urushiol-furfural resin of synthesizing epoxy modification is as resin binder.Development wear-and corrosion-resistant coating also needs to select suitable color stuffing, document announcement, curing key is tired, silica powder can be used as wear resistant filler, and mica powder, iron mica and medium chrome yellow medium yellow can be used as corrosion-resistant color stuffing, in epoxy resin, also with curing key, improve wear resistance.Therefore, in synthetic SUMMARIES EPOXY MODIFIED URUSHIOL-FURFURAL RESIN, add the color stuffings such as curing aluminium, make wear-and corrosion-resistant coating.
