By adopting the high-solid organosilicone modified epoxy floor paint, the time cost for surface drying and hard drying can be shortened under the high-humidity non-ventilation environment; the abrasion resistance, hardness, shock resistance and other mechanical performances can be improved.
Description
Technical field
The present invention relates to a kind of high solid silicon-modified epoxy floor paint under the stuffy environment of high humidity and preparation method thereof that is applicable to.
Background technology
Epoxy resin has the advantages such as good electric property, adhesiveproperties and mechanical property, but after epoxy resin cure, cross-linking density is high, is tridimensional network, causes the material internal stress large, and matter is crisp, thermotolerance, impact resistance variation, has limited its practical application.The rear easy delamination of making moist of common epoxide terrace paint, a little less than uviolresistance, ground is used in the open, if coat common epoxide terrace paint in indoor nonventilated situation, can cause dryly for a long time, and impact is used.
CN102863871A " a kind of terrace solvent type epoxy finish paint " and CN101654583 " compound epoxy flooring coating and preparation method thereof " are described is by ordinary epoxy resin and the two component solvent type epoxy floor paints of common polyamide curing agent.This paint is at humidity<60%, passable during the above construction of temperature 15 degree, but, when humidity >=70%, under stuffy state, paint film can tarnish, and dry for a long time, and the people can't step on.Therefore cause applying.
CN103087613A " for aqueous epoxy floor investment precoat of wet ground and preparation method thereof ", because water-borne coatings volatilization itself is just slow, add stuffy just more difficult doing, and the price of water-base epoxy is solvent type several times.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art part, and a kind of high solid silicon-modified epoxy floor paint under the stuffy environment of high humidity and preparation method thereof that is applicable to is provided.
The objective of the invention is to solve by following technical proposal:
A kind of high solid silicon-modified epoxy floor paint be applicable under the stuffy environment of high humidity is characterized in that composed of the following components by weight percentage:
The A component
Thickening material 0.1-3%
Wherein the weight percent sum of A component is absolutely;
The B component
Solidifying agent 100%
A component and B component 10:1-5:1 are by weight proportion evenly mixed.
Modifying epoxy resin by organosilicon of the present invention is made by polysiloxane and bisphenol A type epoxy resin.
The mixture that solvent of the present invention is toluene, pimelinketone, propyl carbinol and hexone.
Pigment of the present invention is all pigment dyestuff and wherein one or more of mineral dye such as titanium dioxide.
Filler of the present invention is one or more in talcum powder, water-ground limestone, ground barium sulfate, barium sulfate and silica powder.
Solidifying agent of the present invention is a kind of in mannich base, polyethers, aromatic amine and aliphatic cyclic amine.
A kind of as described above preparation method who is applicable to the high solid silicon-modified epoxy floor paint under the stuffy environment of high humidity is characterized in that its preparation process is as follows:
The preparation process of A component:
A, in clean decomposition cylinder, add partial solvent and modifying epoxy resin by organosilicon, start dispersion machine, rotating speed is adjusted to 300-500 turn/s and is stirred.
B, add part defoamer, thickening material, stir evenly after whole dispersion agents, then add whole pigment and filler, rotating speed is increased to 1500 turn/s, carry out high speed dispersion 30 minutes.
C, material is sent in sand mill and ground, after mesh-of-grind is qualified, this material is evacuated to paint mixing kettle with pump.
D, material is put in paint mixing cylinder, rotating speed is adjusted to 1000 turn/s left and right, then adds remaining modifying epoxy resin by organosilicon, defoamer, thickening material and solvent, whole flow agents, stir 15 minutes, to be detectedly gets final product after qualified;
By A component and B component, 10:1-5:1 can application after evenly mixing by weight proportion.
Epoxy resin has the advantages such as good electric property, adhesiveproperties and mechanical property, but after epoxy resin cure, cross-linking density is high, be tridimensional network, cause the material internal stress large, matter is crisp, thermotolerance, impact resistance variation, and under stuffy state, paint film can tarnish, and it is not dry for a long time, limited its practical application, adopt the properties-correcting agent of the organosilicon such as polysiloxane as epoxy resin, owing to thering is consistency preferably between the two, thereby significantly improved thermotolerance and the mechanical property of epoxy resin.
Major cause is that the main chain of modifying epoxy resin by organosilicon is the backbone be formed by connecting with inorganic Si-O-S key, and the bond energy of Si-O key reaches 451.4kJ/mol, much larger than the 355.3kJ/mol of C-C bond energy.When silicone content is 16.7%, the mechanical property of compound system is significantly improved, and its tensile strength, elongation at break reach respectively 54.86MPa, and 9.43%, improved respectively 15.6% and 29% than unmodified pure epoxy resin.
The method that the present invention takes is to select modifying epoxy resin by organosilicon and solidifying agent, selects specially the solidifying agent for high humidity.Because different solidifying agent can cause different surface effects, according to different requirements, to different solidifying agent, will adopt different defoamers, wetting agent, dispersion agent, thickening material and flow agent, realize required effect.
The invention has the beneficial effects as follows:
1, for coastland, sough, underground garage, tunnel, the humidity such as cavern >=70%, and in nonventilated situation, floor paint of the present invention can, in relatively short time drying, the time that has greatly shortened surface drying and done solid work, have been accelerated construction speed.
2, the present invention can, according to different demands, select different solidifying agent and other additive to realize gloss and the hardness on required surface.
3, mechanical properties such as surface hardness of the present invention, sticking power, wear resistance, shock resistance etc. all are improved.
