Description
Technical background:
The invention belongs to the building ground floor material, what relate generally to is a kind of novel solvent-free antistatic epoxy floor paint.
Prior art:
Along with development of high-tech and widespread use, electrostatic problem more and more causes the attention of each side.Terrace is owing to often be subjected to friction to gather a large amount of static charges easily, thereby hinders production process and quality product, and is heavy then cause accidents such as fire, blast.Antistatic floor coatings is as a kind of functional coating, it can give terrace electroconductibility to eliminate electrostatic harm, and because its production unit is simple, easy construction, with low cost, thereby be widely used in fields such as electronics, building, aviation, military affairs over nearly 10 years.
Whether Antistatic Paint has electroconductibility according to filmogen, can be divided into two big classes: addition type Antistatic Paint and non-addition type Antistatic Paint.There are a lot of difficulties in synthetic, the construction of non-addition type Antistatic Paint, and also than higher, performance is not ideal enough for cost, so be not widely used as yet.In the addition type Antistatic Paint, the kind of conductive filler material has determined the electroconductibility of coating.Conductive filler material commonly used comprises that metal is that filler, carbon are filler, burning system filler and complex conductive fillers etc.Metal is that filler exists and to cost an arm and a leg or shortcoming such as oxygen-proof property difference; Carbon is that filler also has problems such as bad dispersibility, color be single; Burning system filler is not because technology and cost problem obtain widespread use at present; Complex conductive fillers does not meet strict day by day environmental requirement owing to comprise harmful heavy metals such as tin, antimony, indium.
For avoiding outside the deficiency of the prior art, the invention provides a kind of addition type antistatic floor coatings.It adopts novel four acicular type zinc oxide crystal whisker as conductive filler material; And selected compound wetting dispersion system for use, solved the problem that the easy loose colour of non-solvent epoxy terrace paint grows dim preferably; In addition, adopted modification cycloaliphatic amines solidifying agent.Finally filming reaches mirror effect, good physical and chemical properties, and anti-static effect is good, lasting; The coating application performance is good, and solvent-free, no poisonous metal, is beneficial to environmental protection.
Summary of the invention:
Novel solvent-free antistatic epoxy floor paint of the present invention is a two-pack, and each component composition and weight percent are as follows:
The first component:
Liquid epoxies 50～70%
Reactive thinner 5～8%
Wetting dispersing agent A 0.3～0.8%
Wetting dispersing agent B 0.2～0.5%
Defoamer 0.2～0.5%
Flow agent 0.1～0.3%
Anti-sedimentation agent 0.3～1%
ZnOw 15～30%
Mill base 1～5%
The second component:
Modification cycloaliphatic amines solidifying agent 90～100%
Siccative 0～10%
First, second set of dispense ratio is 4: 1.
The synthetic resins kind that is applicable to terrace paint at present has Resins, epoxy, urethane, acrylate, unsaturated polyester etc.Because Resins, epoxy all has good cohesive force to various base materials, and over-all properties is better, thereby is used widely.Selected the low molecular weight liquid epoxy (about epoxy equivalent (weight) 190) of bisphenol A-type among the present invention for use, its resistivity is less relatively, and low, the easy solvent free of viscosity, the D.E.R 331 of for example homemade E51, U.S. Dow chemical company, the Shell 828 of U.S. Shell Co. Ltd etc.
Adopted a kind of novel conductive filler material-four acicular type zinc oxide crystal whisker (ZnOw) among the present invention, compared with existing conductive filler material, ZnOw has following advantage:
1, can give material electroconductibility efficiently.ZnOw has unique solid four acicular structures, can form very effective three-dimensional netted conductive channel in system when it is distributed in the base material, thereby required addition is much smaller than sphere or laminal filler; And this electroconductibility is electronic conduction, and stability is high.
2, white.The electroconductibility of ZnOw is to utilize the electroconductibility of its monocrystalline itself, rather than by the secondary of top coat and plating mode conduction, and this whisker is water white monocrystalline, and itself does not have color emissivity whisker, and it can be combined to form pure white or other shades of colour with pigment etc.
3, owing to the high strength and the high-modulus of this product, therefore not only can not influence the mechanical property of coating, can strengthen shock-resistance, weathering resistance and the sticking power of coating on the contrary.
4, this product does not contain harmful or radioactive substances such as tin, antimony, indium, is beneficial to environmental protection.
Because density and particle diameter difference are big between the different pigment, and some pigment easily flocculates, and so just causes the separation of pigments system, and this is one of generation loose colour major reason of growing dim.Particularly outstanding in non-solvent epoxy terrace paint system, therefore must select suitable wetting dispersing agent, make colo(u)rant dispersion stable.For arriving this purpose, used the compound system of wetting dispersing agent A and B in the present invention's prescription.Wherein dispersant A is a high molecular polyurethane-type dispersion agent, as BYK 163 of the DEUCHEM DP-983 of the EFKA 4009 of Dutch EFKA company, the modest company of Taiwan moral and German Bi Ke company etc., its an amount of use can make pigment separate flocculation fully, reaches dispersion effect preferably; Dispersant B is the unsaturated carboxylic acid class dispersion agent that contains organic modified polyorganosiloxane, and as EFKA 5064 and BYK P104S etc., it can effectively control pigment flocculation, and the two compound use can be reached the good anti-loose colour effect of growing dim.
Also comprise reactive thinner epoxy propane butyl ether (trade(brand)name BGE), aerosil class anti-settling auxiliary agent (trade(brand)name-white carbon black), general defoaming agent (as EFKA 2722, DEUCHEM 5500 and BYK 066 etc.) and general flow agent materials such as (as EFKA 3777, DEUCHEM876 and BYK 354 etc.) in the first component prescription of the present invention, make system have package stability, good construction performance and film-formation result preferably, also can add an amount of mill base modulation required color according to actual needs.
Modification cycloaliphatic amines solidifying agent described in the second component prescription of the present invention, the mixed system that it and first component form can be in ambient cure, and viscosity is low, application property good, dry back gloss of film height, color is soft, stable, and has good physicochemical performance.Look ambient temperature situations and can add 0～10% siccative, as 2,4,6-three (dimethylamino methyl) phenol (trade(brand)name DMP-30).

2, take by weighing ZnOw by formula ratio, drop in the above-mentioned base-material under stirring at a slow speed, middling speed (500～800 rev/mins) was disperseed 15～30 minutes then, obtained white paint;
3, mix to required color with mill base and above-mentioned white paint;
4, filter and package and to obtain the first component.
The second component:
1, takes by weighing modification cycloaliphatic amines solidifying agent and siccative by formula ratio, drop into successively and disperse in the cylinder, high speed dispersion (1000～1500 rev/mins) 5～15 minutes;
2, filter and package and to obtain the second component.
Product antistatic effect of the present invention is good, lasting, not influenced by time, temperature, humidity etc.; Coating surface is level and smooth, attractive in appearance, reaches mirror effect; Wear-resisting, withstand voltage, shock-resistant, certain elasticity is arranged; Resistance to chemical attack, particularly alkaline resistance properties are good; Solvent-free, no harmful heavy metal is beneficial to environmental protection.
