Problems solved by technology

Both of these two insulation layers have defects: thermal insulation mortar is generally mixed with thermal insulation materials such as expanded polystyrene particles and expanded perlite particles in cement, and its waterproof performance is poor. If cracks occur in the outer wall, rainwater will enter the cracks. The thermal insulation inner layer of the wall, and the thermal conductivity of water is relatively large, there is water in the inner layer of the wall, the thermal insulation effect is poor, and it will cause mildew and damage to the inner layer of the wall
At present, the polystyrene board and organic polymer insulation materials such as polyurethane and organic polymer insulation materials are constructed in one construction. This technology has better insulation effect, but the construction time is longer, the construction cost of insulation is high, and the construction is difficult. It is also relatively large, and there is a fire hazard in the process of construction and use.
Some construction units add excessive flame retardants to organic polymer insulation materials. Although this can prevent fires, it will increase the amount of smoke and smoke toxicity when organic polymer insulation materials are burned.

Abstract

The invention discloses a waterproofing agent for a thermal insulation cement mortar. The waterproofing agent is potassium n-arachidate. The invention also discloses the thermal insulation cement mortar. The thermal insulation cement mortar comprises Portland cement, a thermal insulation material and the waterproofing agent, the water proofing agent is the potassium n-arachidate, and the saturatedwater absorptivity of the thermal insulation cement mortar is equal to or less than 1.2%. The waterproofing agent is applied to the cement mortar to make the cement mortar have the lightweight, thermal-insulating and waterproof performances, and cooperates with the heat insulation material to ensure the waterproof performance and ensure the strength demand of the cement mortar.

Description

technical field [0001] The invention designs a waterproofing agent and its application, belonging to the technical field of chemical materials. Background technique [0002] In recent years, great progress has been made in my country's building energy-saving work, and the thermal insulation technology of building exterior walls is particularly prominent. Commonly used for external wall insulation are thermal insulation mortar and external polystyrene board, polyurethane and other organic polymer thermal insulation materials. Both of these two insulation layers have defects: thermal insulation mortar is generally mixed with thermal insulation materials such as expanded polystyrene particles and expanded perlite particles in cement, and its waterproof performance is poor. If cracks occur in the outer wall, rainwater will enter the cracks. The inner layer of the wall is insulated, and the thermal conductivity of water is relatively large. If there is water in the inner layer o...
