Abstract

The invention discloses a corrosion-resistant permeable polymer sealing waterproof agent and a preparation method thereof. The corrosion-resistant permeable polymer sealing waterproof agent is prepared from, by weight, 35 to 50 parts of modified urea-formaldehyde resin composite emulsion, 15 to 30 parts of a corrosion-resistant filler, 0.5 to 1 part of methyltrihydroxysilane, 3 to 5 parts of a water reducing agent and 20 to 30 parts of deionized water. The preparation method comprises the following steps: adding the modified urea-formaldehyde resin composite emulsion, the corrosion-resistant filler and half of deionized water into a beaker, heating, stirring and reacting for 30 minutes to obtain a primary material; adding methyltrihydroxysilane, the water reducing agent and the other half of deionized water into the primary material, and continuously stirring for 2 hours to obtain the corrosion-resistant permeable polymer sealing waterproof agent. Trifluoromethanesulfonic acid is added as a catalyst to promote a ring opening process to prepare a composite liquid which is silicone oil with a hydrogen-containing end group; and then the modified urea-formaldehyde resin composite emulsion is prepared from the composite liquid in step S3 and the modified urea-formaldehyde resin emulsion, and the emulsion can endow the prepared waterproof agent with excellent waterproof performance.

Description

technical field [0001] The invention belongs to the technical field of waterproofing agent preparation, in particular to a corrosion-resistant permeable polymer sealing waterproofing agent and a preparation method thereof. Background technique [0002] Buildings will involve waterproofing projects, such as exterior walls, roof floors, kitchens, bathrooms, basements, and rooms with water will involve sealing leaks, waterproofing and anti-seepage and old seepage treatment; reservoirs, water towers, tunnels, water conservancy projects, bridges Projects such as , docks, sewage treatment plants, agricultural ditches and underground civil air defense are all inseparable from leak sealing and waterproofing. The leak sealing, waterproof and anti-seepage construction of traditional building materials unfortunately does not have corrosion resistance, and it is very distressing to repair and repair in just a few years. [0003] Chinese invention patent CN104745144A is a nano-sealing w...
