Description

A kind of fluorocarbon coating for the erosion of paralic environment antiseptic concrete
Technical field
The present invention relates to a kind of paint fields, in particular for the fluorocarbon coating of paralic environment antiseptic concrete erosion.
Background technique
Concrete structure is used for a variety of occasions at this stage, however, being in paralic environment due to the corrosive environment of ocean harshness Concrete by sunlight exposure, humid air, acid-alkali salt etc. corrode.It was verified that concrete surface protective coating is wherein Most simple and effective measure.The coating of antiseptic concrete erosion at present mainly has epoxy coating, acrylate paint, organic siliconresin to apply Material etc..Although these coating have excellent antiseptic property, also have the shortcomings that respective.Epoxy coating is due to epoxy molecule In contain ehter bond, molecular resin degradable chain rupture under ultraviolet light irradiation, so the outdoor weathe resistance of film is poor, easy loss of gloss and powder Change;And big to the dependence of temperature and humidity when epoxy resin cure, internal stress is big after solidification, and heat resistance is undesirable.Propylene Acid esters water-resistant coating is poor, low temperature easily becomes fragile, high temperature becomes glutinous and loses by force, so as to cause the coating easily glutinous dirt, low contamination resistance.It is organic Silicon resin coating has volatility, does not meet environment protection requirement.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, a kind of water-based fluorocarbon for antiseptic concrete erosion is provided Coating carries out long-effective protection to concrete using the weatherability of fluorine-containing lotion, heat resistance, corrosion resistance and durability, Using water as decentralized medium, organic solvent is free of, environment protection requirement is met.
The present invention to achieve the above object, using following technical scheme: it is a kind of for antiseptic concrete erosion water-based fluorocarbon Coating, by mass percentage, including following component:
Make fluorine-containing lotion 44-48% by oneself;

Talcum powder 6-9%;
Dispersing agent 5,040 0.2%;
Wetting agent CF-10 0.2%;
Organic silicon defoamer 110 0.2%;
Coalescing agent alcohol ester ten two 3%;
Antifreeze glycol 1%;
Coupling agent KH-550 0.4%;
Multifunctional assistant 2-amino-2-methyl-1-propanol 0.2%;
Polyurethane alkali-swelling type thickener 0.5%;
Levelling agent RM-2020 0.3%;
Water 22%.
The aqueous fluorocarbon coating is gradually added titanium the preparation method comprises the following steps: a certain amount of water is added in a reservoir in proportion White powder and talcum powder, while dispersing agent and wetting agent are added, defoaming agent is added, levelling agent is dispersed to uniformly using dispersion machine; In finely dispersed slurry, aqueous fluorine-containing acrylic emulsion is added, is eventually adding coalescing agent, coupling agent, multifunctional assistant, Antifreezing agent and thickener continue to be dispersed to system and are uniformly mixed, and obtain the antiseptic concrete erosion fluorocarbon coating.
The self-control fluorine-containing lotion, the preparation method comprises the following steps: equipped with condenser pipe, thermometer, nitrogen conduit four OP-10/SDS compound emulsifying agent, pH adjusting agent NaHCO3 and suitable deionized water is added in mouth flask, stirs evenly.With perseverance A certain proportion of MAA, MMA, BA mixed monomer solution is added dropwise in pressure dropping funel, is added dropwise to complete in 3h.Pre-emulsification is good Monomer take out half after be warming up to 70 DEG C, and first part's APS aqueous solution is proportionally added dropwise, when mixed liquor present it is light When blue, it is initially added into the pre-emulsification of taking-up good monomer and DFMA, with second part APS aqueous solution, controls lotion and initiation The rate of addition of agent makes system keep light blue and constant temperature 1.5h.After being added dropwise, 80 DEG C are slowly warming up to the reaction was continued 2h, Obtained light blue lotion is cooled, pH to 7 or so is adjusted and fluorine-containing lotion is obtained by filtration, is sealed spare.
Technique effect and advantage of the invention is:
1), the present invention provides a kind of preparation process is relatively easy, the good fluorocarbon coating of each component compatibility utilizes methyl Dodecafluorhe-ptylacrylate prepares resin by emulsion polymerization with acrylate monomer, the low-surface-energy etc. that fluorochemical monomer is had Advantageous property is combined with the light of acrylic acid, heat, chemical stability, and it is mechanical strong to improve to introduce acrylate cross linked monomer Degree.
2), antiseptic concrete fluorocarbon coating of the present invention has excellent corrosion resistance;
3), antiseptic concrete fluorocarbon coating of the present invention has the excellent performances such as weather-proof, ageing-resistant;
4), antiseptic concrete fluorocarbon coating of the present invention improves coating hardness, can enhance the protection effect to concrete construction Fruit.
