Description
Technical field
The present invention relates to a kind of graphite ene-type fire-resistant anticorrosion paint is and in particular to a kind of graphite ene-type high-temperature resistant anti-corrosive applies
Material and preparation method.
Background technology
Usually, high-temperature resistant coating refers to long-term physical and chemical performance can be kept normally to play higher than at 200 DEG C
The functional material of effect.High-temperature resistant coating is broadly divided into three major types：Organic coating, inorganic coating and an organic inorganic compounding apply
Material.The heat resistance performance of inorganic coating is excellent, but the paint film bad adhesion being formed, fragility is big, the requirement to ground is higher；
Organic coating can decompose under high temperature (250 DEG C), poor durability, have some impacts to environment, so the present invention is using must be to have
Machine-inorganic compounding coating, paint film is by realizing the high temperature dwell to matrix at high temperature from organic type to the transformation of inorganic type
Shield.
Graphene is by the two-dimentional honeycomb hexagonal structure of the tightly packed one-tenth of carbon atom, and each carbon atom is SP2Miscellaneous
Change, between carbon atom, connection pliability is good, when exposed to external forces, carbon atom facial disfigurement bends, but the position of carbon atom is not sent out
Life rearranges, and this has been maintained for the stability of structure.Just because of Graphene this lattice make it have good pliable and tough
The performance such as property and adhesive force.Being layering of Graphene can form the isolation layer of densification, the extraneous infiltration to paint film for the water of suppression
With infiltration, and then can play corrosion-resistant effect.
Corrosion is every year in the loss in national economy up to 2,000,000,000,000 about, the damage causing considerably beyond annual natural calamity
Lose, painting anticorrosion coating is most economical convenient anti-corrosion method, receives the common concern of domestic and international researcher.With each row
The development of each industry, the market scale proportion of anticorrosive paint is increasing, so the performance to anticorrosive paint and purposes propose
Higher requirement.So the invention provides a kind of anticorrosive paint at high temperature is to meet the market demand.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of graphite ene-type fire-resistant anticorrosion paint, it
It is the surface coating for high temp anti-corrosion material, to meet the needs of the face coat to high temp anti-corrosion material for the market.Graphene
Hardness is big and the performance such as good toughness, is added in coating and can improve the property such as pliability, resistance to marring and adhesive force of coating
Energy.
In order to realize above-mentioned goal of the invention, the technical scheme is that：
A kind of graphite ene-type fire-resistant anticorrosion paint is made up of the raw material of following percetage by weight：
Wherein,
Rheological agent uses Degussa model R972；The model GENIOSIL XL of catalyst organofunctional silane
10；Organic titanate is using must be Tyzor PITA；High concentration concentrates aluminum strip and uses Compal WS model, its maximum
Feature is no-solvent type, it is possible to decrease the VOC content in coating；N-butanol, dimethylbenzene and trimethylbenzene adopt commonly organic on market
Solvent；Graphene uses model ZXC-II of our company's production.
A kind of described graphite ene-type fire-resistant anticorrosion paint and preparation method preparation process are：
A. according to a certain amount of polymethyl siloxane, rheological agent, aluminum oxide microplate placed in the vessel with rotating speed 1200r/
Min, stirs 30 minutes；
B. high concentration is concentrated aluminum strip and Graphene adds in above-mentioned mixed solution, stir 45 minutes；
C. continue to add organofunctional silane, organic titanate, n-butanol, dimethylbenzene, after mixing, add front three
Benzene, controls the viscosity of coating by the amount adding trimethylbenzene.
D. final viscosity can be it is desirable to solid content be in 75-80% for 90-100KU, and solid volume is in 52-58%, VOC
Content is less than 380g/L.
Technical scheme advantage is：
(1) thickness of paint film can be improved using Graphene fire-resistant anticorrosion paint, maximum is up to 200 μm.
(2) using the high methyl silicone resins of low viscosity and inorganic content to merge pigment, filler, catalyst,
Solvent and Graphene film forming at 400 DEG C of high temperature.
(3) after film forming long-term at 1000 DEG C of high temperature the adhesive force of (short-term is at 1800 DEG C of temperature) paint film will not change
Become.
(4) paint film is tough and tensile at high temperature for paint film, and resistance to marring is strong.
