Abstract

The invention relates to the field of waterproof sealing of buildings, and specifically relates to an intumescent waterproof sealing material. The intumescent waterproof sealing material is prepared from the following raw materials in parts by mass: 60-100 parts of geopolymer, 50-135 parts of water glass, 5-60 parts of sodium hydroxide, 10-40 parts of water, 2-6 parts of a foaming agent and 2-6 parts of a foam stabilizer. In addition, the invention further provides a construction method of the intumescent waterproof sealing material. The raw materials of the intumescent waterproof sealing material contain no toxic substances, are environmentally friendly and pollution-free, and the compressive and tensile properties can be improved; closed pores are formed on the intumescent waterproof sealing material through technologies of changing temperature in the foaming process of the geopolymer, performing high temperature sintering and the like so as to achieve the waterproof purpose; the waterproof sealing effect is good; no waterproof agent is added in a process; an environment-friendly effect is achieved; no trouble is brought to physical and psychological health and daily life of people.

Description

technical field [0001] The invention relates to the field of building waterproof sealing, in particular to an intumescent waterproof sealing material and a construction method thereof. Background technique [0002] The rapid process of urbanization has promoted the rapid development of the construction industry, and the construction technology and construction methods of the construction industry have been greatly affected. Because the prefabricated building has the advantages of short construction period and strong controllability, it has been greatly affected. It has promoted the vigorous promotion of urban construction and construction technology, but at the same time it has also brought many problems to be solved, such as water leakage and wet walls. [0003] Water leakage has always been a problem that needs to be solved in prefabricated buildings, and the existing technology to solve the problem of water leakage is to add waterproofing agent to the cement to achieve th...
