Abstract

The invention belongs to the field of building materials and provides a polymer organosilicone concrete waterproofing agent. The polymer organosilicone concrete waterproofing agent is prepared from 30-40 parts by weight of a 40% sodium hydroxide solution, 10-15 parts by weight of methyltrichlorosilane, 10-15 parts by weight of organosilicone, 1-5 parts by weight of lignin, 1-5 parts by weight of sodium citrate, 1-5 parts by weight of magnesium sulfate, 1-5 parts by weight of a polycarboxylic acid water reducing agent and 1-5 parts by weight of ethylene glycol. The polymer organosilicone concrete waterproofing agent has remarkable waterproof effects, the impermeability grade of P20 and high product cleanness, does not easily cause concrete component surface pollution, has mild performances,and does not damage and corrode the concrete components.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a polymer organosilicon concrete waterproofing agent. Background technique [0002] Silicone concrete waterproofing agent can be sprayed to form a transparent protective film on the surface of the building to protect the surface of concrete components from rainwater leakage. At the same time, because the surface is smooth, it is not easy to retain dirt, and the self-cleaning property is good. [0003] At present, there are two types of common water-based silicone waterproofing agents in China: one is strongly alkaline, and will return to alkali after painting, which directly affects the appearance and waterproof life, and has a certain rust effect; the other is emulsion type, and the shelf life of waterproofing agents Short, the waterproof effect is not obvious, and the secondary brushing property is poor. Contents of the invention [0004] In order to overcome t...
