Abstract
The present invention discloses a kind of for netted steelframe structural anticorrosion, the flexible paint of renovation and preparation method thereof, is made of the raw material of following weight parts: 45-60 parts of epoxy resin, 10-15 parts of diluent, 10-15 parts of whisker zinc oxide, 5-10 parts of hollow glass micropearl, 2-4 parts of wetting dispersing agent, 2-4 parts of n-butanol, 10-15 parts of filler.Flexible paint TVOC burst size prepared by the present invention is substantially reduced, and has excellent flexibility, ageing-resistant, color inhibition and Corrosion Protection, can acid and alkali resistance, oil and organic solvent.And a film reaches 100 microns or more, therefore general twice spraying can reach the requirement of construction.
Description
Technical field
The present invention relates to coating and preparation method thereof technical fields, and in particular to one kind for netted steelframe structural anticorrosion,
Flexible paint of renovation and preparation method thereof.
Background technique
The space structure that netted steel frame construction is linked according to certain grid configuration by node by plurality of rods part.Tool
Have the advantages that space-load is small, light-weight, rigidity is big, anti-seismic performance is good；It can be used as gymnasium, cinema, show room, wait
The roof system of the buildings such as the Room, Stadium canopy, hangar, two-way Large Column Spacing workshop.The disadvantage is that intersecting at the rod piece on node
Quantity is more, and fabrication and installation are compared with planar structure complexity.
Netted steel frame construction is for open air, and the greatest problem faced is exactly metal erosion problem.
Metal erosion is that chemistry or electrochemical reaction occur for the medium of metal surface and ambient enviroment slowly from outward appearance to inner essence, is made
Metal is destroyed, and the result of its original performance is lost.People develop the corrosion that many kinds of measures prevents and inhibits metal, wherein
Coating antirust is a kind of effective method.
Currently, being widely used in steel structure surface always by the epoxy coating of main film forming substance of epoxy resin, it is used for
Anticorrosion.However, mostly using organic solvent dissolved epoxy in existing epoxy coating, or using organic solvent as dilution
Agent, therefore, volatile organic compounds (TVOC) discharge amount severely exceed, and cause in serious healthy hidden danger to user of service.
Summary of the invention
The present invention proposes a kind of for netted steelframe structural anticorrosion, the flexible paint of renovation and preparation method thereof, solves existing
The problem of volatile organic compounds (TVOC) discharge amount severely exceeds in some epoxy coatings.
In order to solve the above technical problems, the technical scheme of the present invention is realized as follows:
The present invention provides a kind of for netted steelframe structural anticorrosion, the flexible paint of renovation, is the original by following weight parts
Material is made: 45-60 parts of epoxy resin, 10-15 parts of diluent, 10-15 parts of whisker zinc oxide, 5-10 parts of hollow glass micropearl, profit
2-4 parts of hygroscopic water powder, 2-4 parts of n-butanol, 10-15 parts of filler.
Wherein it is preferred to which the epoxy resin is the bisphenol A type epoxy resin that average degree of polymerization is 1.2-1.6.
Wherein it is preferred to the bisphenol A type epoxy resin that the bisphenol A type epoxy resin is 0.48 by 30-40 parts of epoxide numbers
The bisphenol A type epoxy resin for being 0.51 with 15-20 parts of epoxide numbers forms.
Wherein it is preferred to which the diluent, by 8-10 part 2,3- glycidyl butyl ether and 2-5 parts of polyethylene glycol diglycidyls are sweet
Oily ether composition.
Wherein it is preferred to which the wetting dispersing agent is organo silane coupling agent and/or diethyl diallyl ammonium chloride.
Wherein it is preferred to the filler be mica powder, talcum powder, wollastonite in powder, in white carbon black any one or it is several
Kind.
The present invention and provide it is a kind of for netted steelframe structural anticorrosion, the preparation method of the flexible paint of renovation, including
Following step:
(1) wetting dispersing agent is added in 50~60 DEG C of hot n-butanols and is stirred dispersion, it is micro- that hollow glass is then added
Pearl keeps the temperature 2-4 hours, obtains precast hollow glass microballoon；
(2) epoxy resin and diluent are added in a reservoir, filler and whisker zinc oxide are added after being mixed evenly
Carry out high speed dispersion, be then ground to micron dimension, add precast hollow glass microballoon, after mixing to get.
Beneficial effects of the present invention:
The present invention selects the bisphenol A type epoxy resin that the degree of polymerization is 1.2-1.6, epoxide number is 0.48 and epoxide number is 0.51
It is used in combination, reaches and increase purpose flexible, change the existing problem that epoxy resin is used alone and leads to flexibility difference.
The present invention selects 2,3- glycidyl butyl ether and polyethyleneglycol diglycidylether as diluent, it can plays
The effect for diluting epoxy resin, reducing viscosity, and because bifunctionality molecule degree is big compared with single functionality, it can effectively inhibit small point
Son amount molecule overflows, and the TVOC that improves effectively discharges exceeded problem, and can improve the flexibility one of coating.
The present invention select wetting dispersing agent hollow glass micropearl is pre-processed, thus improve hollow glass micropearl with
The associativity of epoxy resin, after being used cooperatively with whisker zinc oxide and filler, effect effect in labyrinth is obvious, and Corrosion Protection obtains
To greatly improving.
