Plastering mortar, external wall coating and preparation method thereof
The invention relates to plastering mortar, an outer wall coating and a preparation method thereof. The plastering mortar comprises a component A and a component B. The component A comprises the following components in parts by mass: 30-50 parts of cement, 35-60 parts of sand, 6-10 parts of coarse whiting, 0.2-0.4 part of cellulose ether, 0.2-0.5 part of fibers, 2.2-2.6 parts of rubber powder and0.2-1 part of auxiliaries; the component B is prepared from 15-35 parts of silica sol and 65-85 parts of water; wherein the fibers comprise polypropylene fibers and ceramic fibers. The plastering mortar has the advantages of high temperature resistance and low heat conductivity, heat is not easy to accumulate, the phenomena of high-temperature melting and shrinkage of the EPS plate can be effectively avoided, and the plastering mortar can realize thick coating and is not easy to crack and fall off.
本发明涉及抹面砂浆、外墙涂层及其制备方法，该抹面砂浆包括A组分和B组分，其中，以质量百分含量计，A组分包括：水泥30‑50份、砂35‑60份、重钙6‑10份、纤维素醚0.2‑0.4份、纤维0.2‑0.5份、胶粉2.2‑2.6份及助剂0.2‑1份；B组分包括：硅溶胶15‑35份和水65‑85份；其中，纤维包括聚丙烯纤维和陶瓷纤维。该抹面砂浆具有耐高温、传热性低的优点，不易积累热量，进而能够有效地避免EPS板材高温熔化、收缩的现象，且上述抹面砂浆能够实现厚涂而不易开裂、脱落。
