Efficient waterborne nano silicone rubber sealing waterproof agent

Abstract

The invention discloses an efficient waterborne nano silicone rubber sealing waterproof agent. The efficient waterborne nano silicone rubber sealing waterproof agent is prepared by, by weight, 10-15 parts of nano calcium carbonate powder, 18-25 parts of nano-silica dispersion liquid, 20-30 parts of lithium silicate solution, 12-16 parts of polyphenyl particles, 5-8 parts of sodium alkyl benzene sulfonate, 12-22 parts of fly ash, 10-15 parts of calcium stearate, 6-10 parts of Sodium methylsiliconate, 1-3 parts of fluorocarbon surfactant, 2-6 parts of triethanolamine, 1-3 parts of defoaming agent and 8-15 parts of deionized water. The efficient waterborne nano silicone rubber sealing waterproof agent has the advantages that the waterproof agent is safe, nontoxic, free of peculiar smell and environmentally friendly; the waterproof agent can form a film on the surface of concrete and fill pores inside the concrete, and accordingly the permeability resistance of the concrete is increased greatly, and high density inside the concrete is achieved; the waterproof agent is high in adhering force and infiltration capacity, can increase the pressure resistance, heat resistance and cold resistance of the concrete and is promising in application prospect.

Description

technical field [0001] The invention relates to the field of waterproofing agents, in particular to a high-efficiency water-based nano-silicone rubber sealing and waterproofing agent. Background technique [0002] With the rapid development of society, various buildings continue to appear, and people have higher and higher requirements for the safety and reliability of buildings. Concrete is the main building material, and concrete is a brittle material with low tensile strength and limit The tensile strain is small. When the internal stress caused by volume shrinkage due to drying shrinkage, chemical shrinkage, and carbonation shrinkage exceeds its own tensile strength during the setting and hardening process, the concrete will inevitably crack. Therefore, the anti-seepage and waterproofing of construction projects has attracted people's attention, so people invented waterproofing agents for cement concrete. With the advancement of science and technology, people's requireme...

[0002] With the rapid development of society, various buildings continue to appear, and people have higher and higher requirements for the safety and reliability of buildings. Concrete is the main building material, and concrete is a brittle material with low tensile strength and limit The tensile strain is small. When the internal stress caused by volume shrinkage due to drying shrinkage, chemical shrinkage, and carbonation shrinkage exceeds its own tensile strength during the setting and hardening process, the concrete will inevitably crack. Therefore, the anti-seepage and waterproofing of construction projects has attracted people's attention, so people invented waterproofing agents for cement concrete. With the advancement of science and technology, people's requirements for concrete waterproofing agents continue to increase, resulting in the existing The effect of waterproofing agent can not meet people's use requirements;

[0003] The existing high-efficiency water-based nano-silicone rubber sealing and waterproofing agents have certain disadvantages when used. The existing waterproofing agents usually form a hydrophobic film on the surface of the concrete or fill them in the pores inside the concrete, which is relatively simple and not comprehensive in waterproofing. The existing waterproofing agent reduces the compressive effect of concrete while reducing the water resistance of concrete, which does not meet people's requirements for buildings. Therefore, we propose a high-efficiency water-based nano-silicone rubber sealing and waterproofing agent
