Problems solved by technology

Inorganic aluminum salt mortar waterproofing agent has good permeability, but it is acidic, corrosive to metals and will reduce the strength of the mortar, easily causing cracks, the waterproof layer is easy to fail, and the service life is not long, so it gradually withdraws from the waterproof market
Silicone-based mortar waterproofing agent is generally used for water-repellent exterior walls, but if cement sand is mixed and used in toilets and other places where unsaturated water appears, the effect will be very poor

Embodiment 1

[0021] Weigh 100 parts of raw materials by mass, including 35 parts of soap grains, 4 parts of sodium hydroxide, 0.25 parts of sodium silicate, 8 parts of potassium dichromate, 0.2 parts of tributyl phosphate, and 1.0 parts of sodium dodecylbenzenesulfonate , 0.1 part of cellulose, and the rest is water. Put the soap grains and water in the reaction furnace to heat and dissolve, the temperature is 80-100°C; then cool down to 60-70°C, add sodium hydroxide and potassium dichromate and stir at a constant temperature; when the temperature drops to 30-60°C, add Stir tributyl phosphate, sodium dodecylbenzene sulfonate, and cellulose evenly; heat at 60-90°C, stop heating when the reactant becomes thick; and obtain the finished product after cooling.

[0022] The raw materials used should meet the following requirements:

[0023] Cement: Use Portland cement, ordinary Portland cement or slag Portland cement with a strength grade of 32.5MPa and above.

[0024] Sand: medium sand, mud c...

Abstract

The invention discloses a mortar waterproof agent and belongs to the technical field of building waterproofing. The waterproof agent is composed of the following raw materials in percentage by mass: 20-40% of soap grains, 4-8% of sodium hydroxide, 0.1-0.25% of sodium silicate, 3-8% of potassium dichromate, 0.15-0.2% of tributyl phosphate, 0.1-1.0% of sodium dodecyl benzene sulfonate, 0.1-0.5% of cellulose and the balance of water. The mortar waterproof agent disclosed by the invention can be mixed with different materials; the mortar waterproof agent can be used integrally with the functions of waterproofing, thermal insulating, slope finding, leveling and protective layer, and also can be used independently with the corresponding different functions according to different construction parts. Cement mortar or concrete mixed with the waterproof agent does not generate pores and fine cracks, and therefore, the cement mortar or the concrete has permanent waterproofness and the waterproof service life is prolonged. Moreover, the mortar waterproof agent is wide in application range and can be applied to construction on either an upstream face or a downstream face.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to a mortar waterproofing agent. Background technique [0002] Building waterproofing is the measures taken from the building materials and structure to prevent water from penetrating certain parts of the building. Waterproofing is mostly used in roofs, underground buildings, underground parts of buildings, inner chambers and water storage structures that need to be waterproofed. According to the different measures and means adopted, it can be divided into two categories: material waterproof and structural waterproof. Material waterproofing is to rely on building materials to block the passage of water to achieve the purpose of waterproofing or increase the ability to resist leakage, such as waterproofing of coiled materials, waterproofing of coatings, rigid waterproofing of concrete and cement mortar, and waterproofing of clay and lime soil. Structural ...
