Abstract

The invention relates to a flame-retardant polymer cement waterproof mortar which comprises liquid and powder in a weight ratio of 1.0:(3.5-4.5). The liquid comprises the following raw materials in percentage by weight: 50-60% of styrene-acrylate emulsion, 0.10-0.20% of preservative, 0.20-0.30% of dispersant, 0.10-0.20% of defoaming agent and 40-50% of water. The powder comprises the following raw materials in percentage by weight: 40-45% of ordinary Portland cement, 50-55% of quartz sand, 0.02-0.05% of cellulose ether, 0.4-0.5% of water reducing agent and 1.0-3.0% of flame retardant. The flame-retardant polymer cement waterproof mortar can be used for waterproof and moistureproof treatment, effectively solves the problem of waterproofing on the building waterisde or landside, has the advantages of favorable flame retardancy and high binding firmness, is simple and convenient for production, and has favorable flame retardancy and waterproof property when the construction thickness is 1-2mm.

Description

technical field [0001] The invention relates to a building material, in particular to a flame-retardant polymer cement waterproof mortar widely used in toilets, bathrooms, kitchens, balconies and exterior walls. Background technique [0002] In recent years, fires caused by building materials have occurred frequently in our country, especially the huge fires in the CCTV Building, Jinan Olympic Sports Center, Peking University Table Tennis Hall and Taiyuan Iron and Steel Plant have attracted great attention from the competent government departments. [0003] The Fire Department of the Ministry of Public Security organizes the Tianjin Fire Research Institute of the Ministry of Public Security, the Sichuan Fire Research Institute of the Ministry of Public Security and other relevant units to integrate the "Code for Fire Protection Design of Buildings" (GB50016-2006) and "Code for Fire Protection Design of High-rise Civil Buildings" (GB50045-95) revised. A few days ago, the rev...
