Embodiment 1

[0019] Weigh 100 parts of raw materials by mass, of which 40 parts of soap noodles, 5 parts of potassium dichromate, and the rest is water. Put soap particles and water in a reaction furnace to heat and dissolve the temperature at 80°C; then cool to 60°C, add potassium dichromate and stir at constant temperature; stop heating when the temperature is reduced to 30°C; obtain a liquid waterproofing agent after cooling. The finished product is put into a dryer, dried to 5% moisture content and then discharged, put into the crusher and processed into dry powder, and then the finished product is bagged.

[0020] According to the weight ratio: cement 32.3%, medium sand 64.7%, water repellent 1%, redispersible latex powder 1%, water reducing agent 0.5%, wood fiber 0.3%, methyl cellulose 0.2% dry blend to form a dry blend The finished mortar is bagged.

Embodiment 2

[0022] Weigh 100 parts of raw materials by mass, including 35 parts of soap noodles, 4.5 parts of potassium dichromate, and the rest being water. The soap particles and water are heated and dissolved in a reaction furnace at a temperature of 100°C; then, the temperature is lowered to 80°C, and potassium dichromate is added for constant stirring; the heating is stopped when the temperature is lowered to 60°C; the liquid waterproofing agent is obtained after cooling. The finished product is put into a dryer, dried to 5% moisture content and then discharged, put into the crusher and processed into dry powder, and then the finished product is bagged.

[0023] According to the weight ratio: cement 32.5%, medium sand 65%, waterproofing agent 1%, redispersible latex powder 0.5%, water reducing agent 0.5%, wood fiber 0.3%, methyl cellulose 0.2% dry blend to form a dry blend The finished mortar is bagged.

Embodiment 3

[0025] Weigh 100 parts of raw materials by mass, including 40 parts of soap noodles, 4 parts of potassium dichromate, and the rest being water. Put soap particles and water in a reaction furnace to heat and dissolve, the temperature is 90°C; then cool to 70°C, add potassium dichromate and stir at constant temperature; stop heating when the temperature is lowered to 50°C; obtain the finished waterproofing agent after cooling. The finished product is put into a dryer, dried to 5% moisture content and then discharged, put into the crusher and processed into dry powder, and then the finished product is bagged.

[0026] According to the proportions: cement 32.6%, medium sand 65.4%, waterproofing agent 0.9%, redispersible latex powder 0.5%, water reducing agent 0.3%, wood fiber 0.2%, methyl cellulose 0.1% dry mixed to form a dry mixed mortar The finished product is bagged.

[0027] The raw materials used should meet the following requirements:

[0028] Cement: Use Portland cement, ordina...

Abstract

The invention discloses waterproof mortar, belonging to the technical field of building waterproofing. The waterproof mortar consists of the following raw materials in percentage by mass: 32.3-33 percent of cement, 64.7-65.4 percent of medium sand, 0.7-2 percent of waterproof agent, 0.5-2 percent of redispersible latex powder, 0.3-0.6 percent of water reducing agent, 0.3-0.6 percent of wood fiber and 0.1-0.6 percent of methylcellulose, wherein the waterproof agent is prepared by the following steps: mixing and dissolving 20-40 mass percent of neat soap, 3-8 mass percent of potassium dichromate and the balance of water; drying and grinding to obtain dry powder which is the waterproof agent. The waterproof mortar simultaneously achieves the slope finding and protecting effects and has a permanent waterproof effect if the base structure is not changed; the waterproof mortar is suitable for waterproofing works on an upstream face and a downstream face. Meanwhile, no pores or micro cracks are generated, so that the waterproof mortar has permanent water resistance; the waterproof age limit is prolonged, and the application range is wide.

Description

Technical field [0001] The invention belongs to the technical field of building waterproofing, and specifically relates to a waterproof mortar. Background technique [0002] Building waterproofing refers to measures taken from building materials and structures to prevent water from penetrating into certain parts of the building. Waterproofing is mostly used in roofs, underground buildings, underground parts of buildings, and interior rooms and water storage structures that need to be waterproofed. According to the different measures and methods adopted, it is divided into two categories: material waterproof and structural waterproof. Material waterproofing depends on building materials to block the passage of water to achieve the purpose of waterproofing or increase the ability to resist leakage, such as membrane waterproofing, coating waterproofing, rigid waterproofing of concrete and cement mortar, and waterproofing of clay and lime soil. Structural waterproofing is to adopt ...
