Embodiment 1

[0041] This embodiment is used to illustrate the coating disclosed in the present invention and its preparation method and application method.

[0042] The novolak epoxy resin (RF928 that CVC company produces, epoxy equivalent is 210-225g / eq, the carboxyl group nitrile rubber content is 20wt%) of the modified carboxyl group nitrile rubber of 100 parts by weight) and 12 parts by weight of orthoformaldehyde Phenol glycidyl ether (K-100 produced by Atu Company) was mixed uniformly to obtain a resin component.

[0043] Then 60 parts by weight of alicyclic amine (Ancamine 1618 produced by Air Company, amine value is 272mgKOH / g, viscosity 400cps) and 2 parts by weight of 2,4,6-tris(dimethylaminomethyl)phenol (Rebas The K54 produced by the company) was mixed evenly to obtain the curing component. Record as coating A1.

[0044] The resin component and the curing component were mixed, sprayed on the surface of the steel substrate 10 minutes after mixing, and left to stand for 48 hour...

Embodiment 2

[0046] This embodiment is used to illustrate the coating disclosed in the present invention and its preparation method and application method.

[0047] The novolac epoxy resin (produced by CVC company, epoxy equivalent is 182g / eq, the content of carboxyl-acrylonitrile-butadiene rubber is 6wt%) of the carboxyl-terminated nitrile rubber modification of 100 parts by weight and 100 parts by weight of ceramic microspheres (3M company The produced G-800 has an average particle size of 75um and a compressive strength of 413MPa.) Mix evenly to obtain a resin component.

[0048] Then, 30 parts by weight of epoxy resin-modified fatty amine (REX-887B produced by Rebas Corporation, amine value of 310-314 mgKOH / g, viscosity of 250-350 cps) were mixed uniformly to obtain a cured component. Record as coating A2.

[0049] The resin component and the curing component were mixed, sprayed on the surface of the steel substrate 10 minutes after mixing, and left to stand for 48 hours to obtain coa...

Embodiment 3

[0051] This embodiment is used to illustrate the coating disclosed in the present invention and its preparation method and application method.

[0052] The novolac epoxy resin (produced by CVC company, epoxy equivalent is 191g / eq, the content of carboxyl-acrylonitrile-butadiene rubber is 10wt%) of the carboxyl-terminated nitrile rubber modification of 100 parts by weight and 80 parts by weight of ceramic microspheres (3M company Production, the average particle size is 20um, the compressive strength is 480MPa), 1 weight part of phenyl glycidyl ether (K-103 produced by Atu Company) is mixed uniformly to obtain the resin component.

[0053] Then 41 parts by weight of epoxy resin modified fatty amine (D1303 produced by Junjiang Company, amine price is 350-400mgKOH / g, viscosity 250-450cps) and 1 part by weight of 2,4,6-tris(dimethylaminomethyl Base) phenol (K54 produced by Rebas Company) was mixed evenly to obtain a curing component. Record as coating A3.

[0054] The resin comp...

Abstract

The invention provides paint as well as a preparation method and a use method thereof. The paint comprises resin components and curing components, wherein the resin components contain main body resin and simultaneously contains a reactive diluent and / or a ceramic microsphere; the main body resin is terminal butadiene-acrylonitrile-modified novolac epoxy resin; and the curing components comprise a curing agent which contains amine curing agents. The mechanical property and antiseptic property of a coating formed by curing the paint are quiet excellent.

Description

technical field [0001] The invention relates to a paint and its preparation method and use method, in particular to an anti-corrosion paint and its preparation method and use method. Background technique [0002] Corrosion has caused a lot of waste of resources and energy in the national economy. The annual economic loss caused by corrosion in the world is about 1 trillion US dollars, which is the sum of the losses caused by fire, wind disaster and earthquake. As the most effective, the most economical and the most widely used anti-corrosion method, anti-corrosion coating has been widely concerned and valued at home and abroad. With the development of construction, transportation, petrochemical, electric power and other industries, the market size of anti-corrosion coatings has ranked second only to architectural coatings. On the other hand, these fields put forward higher and newer requirements for the variety and performance of anti-corrosion coatings, which in turn promo...
