External wall anti-crack mortar
The invention provides a preparation method of external wall anti-crack mortar. The modified fibers are added, the crack resistance of the mortar is improved, and the fibers are subjected to surface modification, the fibers can be uniformly dispersed in the mortar, and the effects of the fibers can be exerted. Due to the fact that the difference between the heat conductivity coefficients of mortar and the heat preservation plate is large, the deformation amount difference of a plastering mortar layer caused by temperature difference changes is large, and the mortar is prone to cracking, modified plastic particles are added into sand, so that the temperature difference coefficient of the mortar becomes small, cracking of the mortar is prevented from the source, and the mortar has the effects of heat preservation, heat insulation and sound resistance. The modified sealing agent is added, the agglomeration phenomenon in the mortar is reduced, and flame-retardant components exist in the modified sealing agent, spontaneous combustion of the plastic sand at high temperature is prevented, and the safety coefficient of the wall surface is improved.
本发明提供了一种外墙抗裂砂浆的制备方法。其中，添加改性纤维增加砂浆的抗裂性能，对纤维进行表面的改性，使其能均匀的分散在砂浆之中，并且可以发挥出纤维本身的功效。因砂浆与保温板的导热系数相差过大，受温差变化导致抹面砂浆层发生变形的量差很大，砂浆很容易产生裂缝，在砂中添加改性塑胶粒，使砂浆的温差系数变小，从根源上阻止砂浆的开裂，同时使砂浆具有保温、隔热，阻音的功效。加入改性固封剂，减少砂浆中的团聚现象，并且改性固封剂中存在阻燃的成分，防止塑胶砂在高温的情况下自燃，提升了墙面的安全系数。
