Problems solved by technology

[0003] Although the application of polymer clay in building waterproofing is very important, there are only a single variety of polymer clay in the market, and the product quality is uneven, and there are few research reports on polymer clay at home and abroad.
Chinese patent CN104529331A discloses a kind of waterproof polymer beneficial clay, which is made of ordinary Portland cement 40-50%; 60-120 mesh quartz sand 30-45%; 40-70 mesh quartz sand 5-20%; Dispersed latex powder 1.5-3.0%; hydroxypropyl methylcellulose 0.2-0.35%; calcium formate 0.4-0.8%; starch ether 0.05-0.15%; hydrophobic agent 0.2-0.4%; polypropylene fiber 0.07-0.12% as raw materials Formulated, but the patent has a wide variety of raw materials, and the cost of raw materials is high

Embodiment 1

[0018] A kind of polymer beneficial clay, the raw materials used are 50kg of PO42.5 ordinary portland cement, 80kg of quartz sand (fineness 1.0mm), 25kg of ash calcium powder (its Ca(OH) 2 The content is 92%), PVA24887kg, redispersible latex powder 2kg.

[0019] After adding water to the polymer clay to adjust and harden, the cross-sectional structure was observed by scanning electron microscope. figure 1 , figure 2 They are the scanning electron micrographs of the cross-section after the hardening of polymer clay, magnified 50 times and 100 times, respectively. It can be seen from the figure that polyvinyl alcohol and redispersible latex are fully filled in the voids of cement mortar through their excellent fluidity and film-forming properties, so that there are no obvious voids in the cross-section and the compactness is good.

Embodiment 2

[0021] A kind of polymer beneficial clay, its raw materials are PO42.5 ordinary Portland cement 40kg, quartz sand 50kg (fineness 0.5mm), ash calcium powder 10kg (its Ca(OH) 2 The content is 85%), PVA17883kg, redispersible latex powder 3kg.

[0022] According to the implementation standard (Type I) of "DB35 / 516-2005 Yijiao Clay" issued by Fujian Provincial Bureau of Quality and Technical Supervision, the test data is shown in Table 1.

[0023] Table 1 Test results

[0024]

[0025] It can be seen from the results in Table 1 that the performance data of the polymer cement in this example is better than the relevant standards, indicating that it is suitable for waterproofing and pasting of moisture-proof layers and veneer panels with waterproof requirements, and veneer panels.

Embodiment 3

[0027] A kind of polymer beneficial clay, its raw materials are PO42.5 ordinary portland cement 30kg, quartz sand 40kg (fineness 0.8mm), ash calcium powder 15kg (its Ca(OH) 2 The content is 87%), PVA20884kg, redispersible latex powder 4kg.

[0028] According to the implementation standard (Type II) of "DB35 / 516-2005 Yijiao Clay" issued by Fujian Provincial Bureau of Quality and Technical Supervision, the test data is shown in Table 2.

[0029] Table 2 Test results

[0030]

[0031] It can be seen from the results in Table 2 that the performance data of the polymer cement in this example is better than the relevant standards, indicating that it is suitable for waterproofing and impermeability in various construction and facility projects.

Abstract

The invention discloses high-polymer easy plaster and belongs to the field of polymer waterproof mortar. The easy plaster comprises raw materials in parts by weight as follows: 30-50 parts of cement, 40-80 parts of quartz sand, 10-25 parts of ash calcium powder, 3-7 parts of polyvinyl alcohol and 2-4 parts of re-dispersible emulsion powder. The raw materials of the high-polymer easy plaster are simple and easy to obtain, and the product is environment-friendly, has excellent bonding strength, prominent impermeability, suitable setting time and water retention and alkali-resistant properties and the like and can be widely applied to permeability and damp resistance and waterproof plugging of positions such as internal and external walls, basements, swimming pools, toilets, water reservoirs and the like.

Description

technical field [0001] The invention belongs to the field of polymer waterproof mortar, and in particular relates to a kind of polymer beneficial mortar. Background technique [0002] With the improvement of construction engineering quality requirements, problems such as wall waterproofing and wet base surface waterproofing have attracted more and more attention from the construction industry. Polymer cement is an effective means to solve the above problems. Polymer beneficial clay is a single-component, dry powder that mixes a variety of polymer materials with a certain proportion of Portland cement, silt, etc., and is processed through scientific proportioning and special technology. A new type of non-toxic and tasteless rigid waterproof paste material with plugging function integrated. During the production of polymer cement, various polymer particles are evenly distributed between the dry cement powder and fine aggregate, and then mixed with a certain amount of water an...
