Abstract
The present invention relates to technical field of coatings, and in particular to a kind of water-repellent paint that hydrophobicity is promoted.Contain following components in water-repellent paint：Amine terminated polyether, end hydroxy polyether, isocyanates, dioctyl phthalate, chain extender, hydrophobically modified filler, catalyst, hexamethylene, silane coupling agent and auxiliary agent；Wherein, the inorganic filler contained in hydrophobically modified filler is kaolin, talcum powder and precipitated calcium carbonate；Inorganic filler is passed through with the surface treatment of organo silane coupling agent, stearic acid, ethylene glycol and acetic acid modifying agent as main component, so that the hydrophobicity of inorganic filler and being improved with the compatibility of polyether polyols, so as to improve hydrophobic performance, stability of material and the weather resistance of remodeling water-repellent paint.
Description
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of water-repellent paint that hydrophobicity is promoted.
Background technique
Water-repellent paint is a kind of one pack system Environmental-protecwaterproof waterproof paint of liquid construction, is using imported polyurethane performed polymer as base
This composition.Solidify after its aerial moisture contact, can substrate surface formed one layer it is firm tough and tensile jointless
Integral waterproofing film.The construction technology of this coating is simple, and for the structure and property to substrate without particular requirement, bond effect is good, Gu
It is lower to change the time.
Polyurethanes waterproof material in the market has two major classes：First is that conventional polyurethanes class water-repellent paint；This kind of material one
As be made of polyurethane and coal tar as raw material.The tar gas toxicity that it is volatilized is big, and does not allow easy-clear.Still in pin
The polyurethane waterproofing coating sold is that pitch is used to replace coal tar as raw material.When using this coating, general use contains first
The organic solvents such as benzene, dimethylbenzene dilute, these solvents also contain toxic；Another kind of is polymer cement-base waterproof coating.It
The lotion synthesized by a variety of waterborne polymerics is formed with the high grade cement mixed with various additives, flexibility and the cement of polymer
Rigidity becames one, so that it is excellent in terms of impermeability is with the strength of materials.Its advantages are easy for construction, comprehensive costs
It is low, short time limit, and asepsis environment-protecting.But since the hydrophobicity of cement base-material in polymer cement fundamental mode water-repellent paint is poor, because
The waterproof performance of this this coating is generally below conventional polyurethanes class water-repellent paint.Further, since having been used in coating inorganic
The compatibility of filler ingredient, this material and organic polymer is poor, and weatherability is relatively low, and the curing time of coating is more
It is long.
Patent publication No. CN105462479A provides a kind of weather-proof self demixing single-component waterproof coating material of environment-friendly type and its system
