Abstract

The invention provides a quick-hardening anti-seepage joint mixture. The quick-hardening anti-seepage joint mixture is prepared from, by weight, 7-15 parts of high-alumina cement, 30-45 parts of ordinary portland cement, 2-10 parts of gypsum, 60-65 parts of quartz sand, 1-3 parts of a water repellent, 0.2-0.8 part of methyl hydroxypropyl cellulose ether, 7-9 parts of redispersible latex powder, 0.2-1.0 part of a water-soluble organic compound early strength agent and 0.05-0.2 part of an alkyl-carboxyl retarder. By bonding the components of ordinary portland cement, high-alumina cement and gypsum and adding a series of additives such as the water repellant and a water reducer, the quick-hardening anti-seepage effect of the joint mixture can be achieved. The bonding strength of the prepared joint mixture can meet the industry regulation requirement within 24 h, the high-strength joint mixture increases the construction speed and accelerates the construction progress, and due to the good anti-seepage property, the waterproofing and saltpetering preventing properties of the product are better optimized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fast-hardening anti-seepage caulking agent. Background technique [0002] The laying of ceramic tiles has become a common decoration in daily life. From home to hotels and other public places, from the ground to the wall, the decorative effect brought by ceramic tiles is beautiful. However, in the process of laying and laying, bricks and The gaps between the bricks require special treatment. The sealants commonly used to fill the gaps between tiles are easy to get dirty and black, low in strength, and powdery. [0003] In the prior art, CN105198312A discloses a tile grouting agent, the weight ratio of raw materials is: ordinary Portland cement (P.042.4R) 35-60, quartz sand 30-65, mineral oil type defoaming Agent 0.01-0.2, redispersible latex powder 10-30, hydroxypropyl methylcellulose 0.1-0.5, silicone water repellent 0.2-1, anti-efflorescence agent 0.2-1, anhydrou...
