Embodiment Construction

[0026] The components were prepared in the weight ratios shown in Table 1.

[0027] The weight proportion of table 1 embodiment 1~embodiment 3

[0028]

[0029] In the above embodiments, aluminum silicate fiber is used as the inorganic fiber; corn stalk is used as the plant fiber, and its length is less than 0.3 cm; the length of polypropylene fiber is in the range of 1-20 mm; hydroxypropyl methyl cellulose ether is used as the cellulose ether.

[0030] The preparation method is:

[0031] S1: Mix portland cement, polymethyl acrylate latex powder, ethylene-vinyl acetate latex powder, vinyl chloride-vinylidene chloride copolymer latex powder, and polyacrylate latex powder evenly to form mixture A;

[0032] S2: Mix polypropylene fiber, cellulose ether, inorganic fiber, plant fiber, cellulose sulfate, cellulose phosphate, phenyl o-hydroxybenzoate, and polyimide particles uniformly to form a mixture B;

[0033] S3: Mix mixture A, mixture B, quartz sand, gypsum, fly ash, benton...

Description

technical field [0001] The invention provides waterproof mortar, in particular to a corrosion-resistant polymer waterproof mortar, which belongs to the technical field of building materials. Background technique [0002] Various new wall materials (such as concrete hollow blocks, aerated concrete blocks, ceramsite concrete hollow blocks and clay hollow bricks, etc.) have been widely used. The new wall materials can make materials recycled and reduce the impact on the natural environment. purpose of destruction. However, new wall materials generally have shortcomings such as large porosity, strong water absorption, and poor impermeability, which lead to water leakage on the outer wall. Measures for wall leakage. [0003] In addition, buildings are exposed to various harsh conditions in the natural environment, such as floods, snow disasters, acid-base salt erosion, etc., which cause damage to building structural materials and reduce the reliability of buildings. In turn, i...
