Wear-resisting exterior coating and preparation method thereof
technical field:
The present invention relates to building material technical field, specifically one can effectively improve building surface film flexibility, prevent cracking, reduction of erection time, effectively improves wear-resisting exterior coating of the wear-resisting weathering resistance performance of coating and preparation method thereof.
background technology:
Coating is one of indispensable material of building field, and its Main Function is protection building surface, makes it have waterproof, resistant, the feature such as attractive in appearance, and according to the needs of different occasions, coating can also have heat insulation, the resistance to function such as tan by the sun.Existing exterior coating because tack is not good, tends to occur cracking, the situation of peeling off after construction completes, and cannot realize the protection to skin, and not attractive in appearance.Exterior coating when construction present stage, can not be excessive to construction wall surface requirements humidity to be onstructed, generally need to guarantee that substrate surface is dry, otherwise be difficult to film forming or construction quality is influenced, the prolongation that this causes project duration, has caused the waste of human and material resources.
In addition, how effectively improving ageing-resistant, the wear resisting property of the rear coating of construction, is problem demanding prompt solution, and wear-resisting, the weather resistance of coating, have crucial meaning for structural quality.
