Description
Technical field
The present invention relates to epoxy anticorrosion mould-repellant coating.
Background technology
The effect of protective system mainly contains three kinds: the shielding effect of paint film and sheet material pigment, alkalescence or the Low corrison effect of oxidisability pigment and the electro-chemical protection of zinc powder.Wherein, can the shielding effect that the corrosive mediums such as water, oxygen and ion are isolated is the most key.Heavy-duty Coatings In Ocean Chemical Industry conventional mostly at present is solvent based coating.In its film process, the pin hole that solvent evaporates stays, can make corrosive medium ooze and cause corrosion to film.Gained corrosion product expands and racks coating, corrosive medium is spread, makes coating fall in flakes lose efficacy eventually.In addition, for the dope layer of special occasions, require that it is shock-resistant, resistance to elevated temperatures will could meet the demands well, meanwhile, the toughness of paint film is better, then be more not easy damaged and even come off.In addition, the requirement of coating to mildew-resistant is also more and more higher.
Summary of the invention
The object of this invention is to provide the epoxy anticorrosion mould-repellant coating that a kind of antiseptic property is good, impact resistance is good, good toughness, fungicidal properties are good.
For achieving the above object, a kind of epoxy anticorrosion mould-repellant coating, according to weight percent meter, consists of the following composition:
Bisphenol A epoxide resin 30%-40%
Phenolic aldehyde amine 8%-15%
Weight ratio is the protection type mildew-resistant capsule sporozoite of 3:1 and the mixture 5%-10% of rubber powder
Urethane 5%-10%
Nitrile rubber 10%-18%
Sheet high abrasion color stuffing 10%-17%
Dispersion agent 0.5%-0.9%
Defoamer 0.4%-0.8%
Sanitas 0.4%-0.8%
Flow agent 0.2%-0.5%
Deionized water 15%-23%.
Further, described sheet high abrasion color stuffing by 320 orders and content be the glass flake of 2%-4%, the sericite in powder of 160 orders and content to be the glass flake of 3%-6% and content be 5%-7% forms; Above per-cent is all weight percentage.
Further, described dispersion agent is TH-904 or SN-5040.
Further, described defoamer is SN-154 or A10.
Further, described flow agent is RM-2020.
The invention has the beneficial effects as follows: phenolic aldehyde amine, can fast setting at low ambient temperatures as solidifying agent, and has good antiseptic property; The benzene ring structure of this solidifying agent and bisphenol A epoxide resin have better consistency, thus can reduce the viscosity of system further, improve the compatibility of host and solidifying agent.Bisphenol A epoxide resin and paracril first carry out pre-reaction, adding of a small amount of paracril can not form two phase structure, the formation when paracril content reaches certain limit is only had to have being separated of island structure, this can meet uncured front rubber and bisphenol A epoxide resin well miscible, low viscosity characteristics, can rubber phase be separated out after can solidifying again again, produce micron-scale phase separation, improve impact resistance.Urethane and bisphenol A epoxide resin can form semi-intercrossing network (SIPN) and interpenetrating(polymer)networks (IPN) polymkeric substance, SIPN and IPN structure desirable " forcing mutual tolerance " and " synergy " make the snappiness of urethane and the good heat resistance of bisphenol A epoxide resin and cementability organically combine, and obtain good toughening effect.The release actives of the protection type mildew-resistant capsule sporozoite energy continuous and effective in the present invention, itself and rubber powder effect, reach permanently effective mildew-proof function, can also improve the elasticity of paint film.
