Description
Technical field
The invention belongs to paint field, and in particular to a kind of ceramic anticorrosion antiwear two-component coating, more particularly to a kind of to answer
For oil pipeline, ship deck, it is necessary to anti-corrosion, the coating in wear-resisting field.
Background technology
Coating is important metal protection measure.General coating is by resin, filler, auxiliary agent, solvent composition.It is special to apply
Material, can it is solvent-free and as powdery paints.But no matter which kind of type coatings, determine the most important performance of coating is resin with filling out
Material.This means that change resin and filler can just change the performance of coating.
With the change of use environment, there are more requirements to coating performance, coating is not required nothing more than to be had typically to metal
Anti-corrosion protection effect, also require some special functions.For example：Wearability etc., to meet the particular/special requirement of some occasions.Example
Such as, transport containing fine husky pipeline, ship deck, the coating in terms of grinding machinery.
To meet coating in abrasion and the use of corrosive environment, from the composition analysis of coating, it is necessary to change resin or filler,
Or change resin simultaneously with filler to adapt to its use in abrasion and corrosive environment.
In the coating used, epoxy resin is most important anticorrosive paint.Epoxy resin includes bisphenol-A epoxy tree
Fat, bisphenol F epoxy resin and novolac epoxy resin etc..
Novolac epoxy resin has high rigidity, high temperature resistant and acid and alkali-resistance, wear-resisting advantage.
Bisphenol A epoxide resin has viscosity small, the features such as discharging stress.
Bisphenol F epoxy resin pliability is good, and viscosity is low, and stress response to external world is fast.
Exactly difference of these resins on molecular structure, different effects are shown to stress from abrasion.Put into practice table
It is bright：The species of its antiseptic property and stress and the epoxy resin used, molecular weight has close relationship；The larger epoxy of molecular weight
In general, the contraction of generation is smaller for resin, and the stress of generation is smaller.
During the abrasion of coating, the wearability of the filler meeting strong influence coating in coating.It is especially different
The synergistic result of the combination collocation of filler can influence the abrasion of coating.In existing patent and document, to using filler
Resistance to abrasion is improved to have been reported.For example, patent CN104130662A.But these only account for its fillibility, and have ignored and fill out
Effect between material and resin.
Meanwhile, the consistency and elasticity of resin in itself can also influence abrasion performance.In general, coating hardness is higher, wear-resisting
Consumption is better；Elasticity is bigger, and wearability is better.According to such basic understandings, people are trying hard to design wear-resisting and corrosion-resistant painting
Layer.
In conventional wear-resistant paint, people often notice the pliability of coating, big more options polyurethane coating, still
In terms of antiseptic property, compared with epoxy resin, also there is a certain distance in polyurethane coating, and epoxy resin is designed into one kind
The coating of wear-and corrosion-resistant is the major issue for needing to solve.
