Problems solved by technology

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a cement waterproof mortar and its preparation method, which can effectively reduce the weight of the waterproof mortar per unit area through the setting of hollow balls, and effectively reduce the work force of the staff on the one hand. Construction difficulty. On the other hand, compared with the existing technology, it is not easy to cause falling due to heavy weight during construction, thereby effectively ensuring the uniformity of the waterproof layer and reducing construction difficulty. In addition, the anti-seepage ball and poly In the combination of water-emulsion balls, a layer of water-cutting barrier can be formed in the waterproof layer, which can effectively reduce the infiltration of water in all directions, and then significantly improve the waterproof effect during use

Embodiment 1

[0046] see figure 1 , a cement waterproof mortar, comprising the following ingredients in parts by mass: 30-40 parts of Portland cement, 30-50 parts of sand, 3-5 parts of hydrophobic agent, 5-10 parts of polymer silica latex powder, 3- 5 parts of flame retardant, 5-10 parts of hollow balls, the particle size of hollow balls is 3-5mm.

[0047] Polymer silicon emulsion is one or more mixtures of ethylene, vinyl chloride and vinyl laurate ternary copolymer latex powder, vinyl acetate and tertiary carbonic acid ethylene copolymer latex powder, vinyl acetate and ethylene copolymer latex powder, sand is selected The fine sand in the downstream section of the river, and keep the sand particle size not higher than 1mm, so that the particle size is finer, thereby effectively avoiding the formation of voids inside the waterproof layer, so that the waterproof effect is better.

[0048] see figure 2 , The hollow ball is a hollow glass ball.

[0049] A kind of cement waterproof mortar,...

Embodiment 2

[0053] see figure 2 , The hollow ball is a polywater emulsion ball.

[0054] see image 3 The polywater emulsion ball includes two glass hemispheres 1 bonded to each other. The glass hemisphere 1 is a porous structure, and the pores of the glass hemisphere 1 are wrapped with a water-absorbing layer 3. The inner wall of the glass hemisphere 1 is coated with a water-absorbing layer 4. The glass hemisphere 1 The outside is wrapped with an outer protective layer 2, and the glass hemisphere 1 is also filled with water-absorbing powder, such as Figure 4 , the outer protective layer 2 is made of whole starch degradable material, and the water diversion layer 3 is made of water-soluble material. When only using polywater emulsion balls, when the waterproof layer is formed for a period of time, the outer protective layer 2 gradually degrades, making the porous The glass hemisphere 1 is exposed. When water seepage occurs, when water seeps into the glass hemisphere 1 near the crack, ...

Embodiment 3

[0059] see figure 2 , Hollow balls are anti-seepage milk balls and polywater milk balls.

[0060] When in use, before construction, it is used in the same way as ordinary cement, adding water to make a slurry for use.

[0061] It is also worth noting that in the third combination method, the milk-resistant balls are not mixed with other raw materials, but are stored separately and used together with waterproof mortar obtained by mixing other raw materials.

[0062] see Figure 5 The milk-resistant ball includes a shaped metal mesh layer 6, the outer end of the shaped metal mesh layer 6 is wrapped with an outer water-absorbing layer 7, the inner wall of the shaped metal mesh layer 6 is attached with an inner protective layer 5, and the inner protective layer 5 is placed with A plurality of water-absorbing resin balls 8, the upper end of the plastic metal mesh layer 6 is fixedly connected with an outer ventilation rod 9, the end of the inner sheath 5 is fixedly connected with...

Abstract

The invention discloses cement waterproof mortar and a preparation method thereof, and belongs to the field of cement. According to the cement waterproof mortar and the preparation method thereof, the weight of the waterproof mortar in unit area is effectively reduced through arrangement of hollow balls, the construction difficulty of workers is effectively reduced on one hand, and on the other hand, compared with the prior art, falling caused by heavy weight is not prone to occurring during construction, the uniformity of the waterproof layer is effectively guaranteed, and the construction difficulty is reduced. In addition, in the combination mode of anti-seepage emulsion balls and water-gathering emulsion balls, a layer of water stopping barrier can be formed in the waterproof layer, internal seepage of water is effectively reduced in an all-around mode, and then the waterproof effect during use is remarkably improved.

Description

technical field [0001] The invention relates to the field of cement, in particular to a cement waterproof mortar and a preparation method thereof. Background technique [0002] With the development of society, new building materials and construction technologies are constantly appearing, such as aerated concrete, frame structure, etc., but there are certain problems in the use of these materials, especially for the domestic southern market. Air-entrained concrete has a high water absorption rate, and mildew on interior walls often occurs in southern building structures due to high water absorption rate of air-entrained concrete. Therefore, for rainy areas, it is necessary to waterproof the exterior walls of buildings, and choose different waterproof materials according to different decorative materials. Among them, polymer cement waterproof mortar has a higher cost performance as a rigid waterproof material. [0003] At present, the construction thickness of polymer cement ...
