Abstract

The invention discloses a special waterproof agent for buildings. The special waterproof agent is prepared from, by weight, 30-40 parts of n-octyl triethoxy silane, 15-25 parts of acrylic ester, 8-13parts of calcium stearate, 4-9 parts of chopped glass fibers, 7-13 parts of sodium dodecyl benzene sulfonate, 6-11 parts of sodium lignosulfonate, 5-12 parts of silicon dioxide colloidal solution, 3-6parts of aluminum sulfate, 8-14 parts of modified fly ash, 5-9 parts of lotus leaves, 1-2 parts of a bactericide, 2-3 parts of an antifoaming agent and 15-25 parts of water. By compounding of raw materials including n-octyl triethoxy silane, acrylic ester, calcium stearate, silicon dioxide colloidal solution, the lotus leaves and the like, the prepared special waterproof agent for buildings has advantages of great waterproof effects, high viscosity and high adhesiveness.

Description

technical field [0001] The invention belongs to the technical field of waterproofing agents, and in particular relates to a special waterproofing agent for buildings and a preparation method thereof. Background technique [0002] With the development of my country's construction industry, underground projects account for an increasing proportion, so waterproofing is an important issue to ensure the quality of projects. At present, there are many kinds of waterproofing agents, which can be roughly divided into three categories: inorganic-based waterproofing agents, organic-based waterproofing agents, and mixture-based waterproofing agents. These waterproofing agents have played a certain role in waterproofing projects, but there are deficiencies in different degrees, such as: high production costs, too complicated construction operations, different degrees of corrosion to steel bars, and some waterproofing agents produce environmental pollution. Larger, some waterproof effec...
