The invention discloses an anti-falling building outer wall coating, and belongs to the field of building outer wall coatings. A solid coating can be broken through heating change of tearing and refilling particles, a crack buffering layer with blocks and powder is formed, and when the crack buffering layer is subjected to external acting force, the crack buffering layer is stressed to generate an internal migration process, so that acting force is transmitted to the periphery, the force is dispersed, weakened and buffered, and the stressed part is effectively protected against peeling and falling due to damage; and when the external acting force is excessively large and is dispersed and weakened through the crack buffering layer, the remaining acting force reaches the tearing and refilling particles, an outer spherical shell is stressed and broken, a repairing liquid flows out and fills all gaps of the crack buffering layer, the broken crack buffering layer is repaired into a hard whole again, the crack buffering layer recovers to a certain hardness to resist external acting force, and a double compression resistance effect of the crack buffering layer is achieved.
本发明公开了一种具有防脱落的建筑外墙涂层，属于建筑外墙涂层领域，本发明通过撕裂重补颗粒的受热变化，可以引发固体涂层发生碎裂，形成兼具块体和粉体的碎缝缓冲层，当受到外界作用力时，碎缝缓冲层受力会发生内部迁移过程，实现将该处作用力传递至周边部分，对力起到分散、弱化、缓冲的作用，从而有效保护该受力部位不易受到损坏而发生起皮、脱落情况，并且，当外界作用力过大，经过碎缝缓冲层的分散弱化后，剩余作用力到达撕裂重补颗粒时，会导致外球壳受力破裂，修补液流出，填充在碎缝缓冲层的各个缝隙处，重新将破碎的碎缝缓冲层修补成硬质整体，使碎缝缓冲层恢复一定的硬度以抵抗外界作用力，实现了碎缝缓冲层的二重抗压作用。
