停車場环氧地坪塗層為什麼會出現剝離現象

停車庫环氧地坪自上而上一般包括面塗層、中塗層(包括环氧砂漿層和膩子層)、底塗層、細石混凝土基層，环氧地坪是一種高強度、耐磨損、美觀的地板，具有整體無接縫、質地堅實、耐藥品性佳、防腐、防水、防塵、保養方便、維護費用低廉等優點。雖然环氧地坪一般的使用壽命在8-15年，但很多的停車場环氧樹脂地坪往往在2-3年，甚至更短的時間內就會透水地坪出現塗層的剝離破壞的情況。為什麼會出現這樣的現象呢?以下解析一下停車場环氧地坪塗層出現剝離情況的原因所在：
Epoxy floor of parking garage generally includes surface coating, middle coating (including epoxy mortar layer and putty layer), bottom coating, fine stone concrete base. Epoxy floor is a kind of high-strength, wear-resistant, beautiful floor, with overall seamless, solid texture, good resistance to antisepsis, waterproof, dust-proof, easy maintenance. The maintenance cost is low. Although the service life of epoxy floors is generally 8-15 years, many parking lot epoxy floors are often in 2-3 years, or even shorter time will appear coating peeling damage. Why does this happen? The following analysis of the car park epoxy floor coating peeling reasons for the situation:

1、停車場环氧地坪塗層剝離破壞
1. Stripping failure of epoxy floor coating for car parks
环氧环氧地坪塗層大面積剝離破壞主要有兩種情況：
There are two main reasons for the large area peel failure of epoxy floor coating:
a、环氧樹脂層與混凝土基層結合界面破壞，表現為环氧塗層脫落，混凝土基層正常無損，大面積出現，直接原因是界面黏結力不足。
A. The failure of the interface between epoxy resin layer and concrete base is characterized by the shedding of epoxy coating, the normal and nondestructive behavior of concrete base, and the large area of it. The direct reason is the insufficient interfacial adhesion.
b、环氧塗層與混凝土基層表面砂漿結合緊密，破壞面出現在混凝土基層內部，破壞面位於混凝土基層的砂漿平面。這種破壞形式一般大面積出現，直接原因是混凝土的抗拉強度不足。停車場环氧地坪塗層的不同塗膜層也有出現剝離的情況，主要原因是不同塗膜之間的黏結力不足，一般出現於局部，大面積出現並不常見。
B. The epoxy coating is tightly bonded with the mortar on the surface of the concrete base, the failure surface appears in the interior of the concrete base, and the failure surface lies in the mortar plane of the concrete base. This failure occurs in a large area. The direct reason is that the tensile strength of concrete is insufficient. Different coatings of epoxy floor coatings in parking lot also have peeling off, the main reason is that the adhesion between different coatings is insufficient, generally occurring l彩色沥清地坪ocally, large area is not common.
2、环氧地坪塗層出現凸起及裂縫
2. Epoxy floor coating is convex and cracked.
环氧地坪塗層局部凸起，主要表現為出現直徑2～5mm和30～50mm不同程度的凸起，主要原因是基層幹燥不夠，氣體集聚在漆膜下面，塗膜面吸收水分而凸起，或者是由漆膜固化時有雜質未清理幹凈。塗層出現裂縫，表現為塗膜收縮開裂和塗層因基層裂縫而拉裂。
The local protrusion of epoxy floor coating is mainly manifested by the protrusion of 2-5 mm in diameter and 30-50 mm in diameter. The main reason is that the base is not dry enough, the gas gathers under the film, the surface of the film absorbs moisture and protrudes, or the impurities are not cleaned up when the film solidifies. The cracks occurred on the coating, which showed the shrinkage cracking of the coating and the cracking of the coating due to the cracks at the base.
