Adhesive mortar special for self-anti-cracking ALC (autoclaved lightweight concrete)
The invention discloses adhesive mortar special for self-anti-cracking ALC (autoclaved lightweight concrete). The adhesive mortar is prepared from the following components in percentage by weight: 50 to 62 percent of sand, 32.5 to 40 percent of cement, 1 to 2 percent of redispersible latex powder, 1.5 to 2 percent of polypropylene fiber, 0.5 to 1 percent of acrylic ester, 1 to 1.5 percent of cellulose ether and 1.5 to 3.5 percent of styrene-butadiene emulsion. Through mutal cooperation of different components, the adhesive mortar has good water-retaining property, high adhesive strength and strong anti-cracking capability, the water-retaining property of the adhesive mortar can be greatly improved by adding the cellulose ether, hydroxyl groups on cellulose ether molecules and oxygen atoms on ether bonds can be associated with water molecules to form hydrogen bonds, free water is changed into bound water, and thus good water retention effect is achieved. The added polypropylene fiber can improve the toughness and the fatigue resistance of the adhesive mortar so as to significantly reduce the number of the cracks and reduce the possibility of the generation of the through cracks, and the added redispersible latex powder, the added styrene-butadiene emulsion and the added acrylate can improve the adhesive property of the mortar and improve the wear resistance of the mortar.
本发明公开了自防开裂ALC专用粘结砂浆，包括按照重量百分比计的以下组分：砂50％‑62％、水泥32.5％‑40％、可再分散乳胶粉1％‑2％、聚丙烯纤维1.5％‑2％、丙烯酸酯0.5％‑1％、纤维素醚1％‑1.5％和丁苯乳液1.5％‑3.5％，本发明通过通过不同组分的相互配合，使粘结砂浆具有良好的保水性，而且粘结砂浆粘结强度高，防开裂能力强，通过加入的纤维素醚可以大大的提高粘结砂浆的保水性，纤维素醚分子上的羟基和醚键上的氧原子会与水分子缔合成氢键，使游离水变成结合水，从而起到很好的保水作用，通过加入的聚丙烯纤维可以提高粘结砂浆的韧性、抗疲劳性，从而显著减少裂缝的数量，降低生成贯通裂缝的可能性，通过加入的可再分散乳胶粉、丁苯乳液和丙烯酸酯可以增加砂浆的粘结性能，提高砂浆的耐磨性。
