Embodiment 1

[0037] Example 1: It is a basic embodiment of a one-component flexible polymer waterproof mortar material of the present invention, which includes the following dry powder, and the components are calculated by weight percentage: 30% to 65% of cement; 30% to 65% of sand; Rubber powder 1%~5%; cellulose≤0.3%; fiber≤0.3%; silica fume≤5%; defoamer 0.05%~0.5%; water reducing agent 0.05%~0.5%; ; The remainder is silicon-aluminum material;

[0038] Select the specific powder according to the above selected value range, and add it to the mixing equipment to fully stir and dry mix. There is no limit to the order in which each powder is added when adding the material. After uniform mixing, a single-component flexible polymer can be obtained. Finished waterproof mortar material.

Embodiment 2

[0039] Example 2: is a further embodiment of embodiment 1. The difference from Example 1 is: the components are calculated by weight percentage: cement 35% ~ 60%; sand 32% ~ 60%; rubber powder 1.5% ~ 5%; cellulose ≤ 0.25%; fiber ≤ 0.25% %; silica fume ≤ 4%; defoaming agent 0.1% ~ 0.4%; water reducing agent 0.1% ~ 0.4%; waterproofing agent 0.2% ~ 5%; the balance is silicon aluminum material.

Embodiment 3

[0040] Example 3: is a further embodiment of embodiment 1. The difference from Example 1 is that the cement is ordinary Portland cement, selected from ordinary Portland cement with cement strength grades of 32.5, 42.5 and 52.5; sand. The rubber powder is based on vinyl acetate-ethylene emulsion or vinyl acetate-ethylene tertiary carbonate emulsion, which is spray-dried and added with mineral materials less than or equal to 10% of the total amount of the finished product as a solid powder dispersant, and finally forms a flowable redispersible latex powder. The cellulose is methyl cellulose ether or hydroxypropyl methyl cellulose ether, and the viscosity is selected from 3500 to 63000 mPa·s. The fibers are polypropylene fibers of 3-9mm. Silica fume has a specific surface area greater than or equal to 2500 m 2 / kg less than or equal to 25000 m 2 / kg of commercially available silica fume material. The defoamer is a silicone oil-based powder defoamer; the water-reducing agen...

Abstract

The invention relates to a one-component flexible polymer waterproof mortar material and a method for preparing waterproof mortar by using the one-component flexible polymer waterproof mortar material. The waterproof mortar material comprises the following powder: cement, sand, rubber powder, cellulose, fiber, silica fume, a defoaming agent, a water reducing agent, a waterproof agent and the balance of a silicon-aluminum material. According to the selected value ranges, the specific powder is selected, matched and added into a stirring device for sufficiently stirring, and a finished product of the one-component flexible polymer waterproof mortar material can be obtained after evenly mixing. The method for preparing waterproof mortar comprises the steps of burdening, adding water and mixing, and treating. The one-component flexible polymer waterproof mortar material and the method have the advantages that the flexible polymer waterproof mortar obtained after evenly mixing the waterproof mortar material and the water has the durability of mortar and certain flexibility so as to prevent cracking and water seepage, and meanwhile the flexible polymer waterproof mortar is ultra-thin, high in anti-permeability, high in wear resistance, good in anti-permeability and waterproof performance, proper in strength, and good in flexibility, impact resistance and cohesive property. The preparation method of the waterproof mortar is easy to grasp and high in efficiency, and can be used for guaranteeing the product quality.

Description

technical field [0001] The invention relates to a single-component flexible polymer waterproof mortar material and a method for preparing waterproof mortar by using the same, which is suitable for waterproofing of engineering structures, especially for waterproofing of roofs, exterior walls and underground projects including basements, and belongs to the technical field of building waterproofing. Background technique [0002] Waterproof technology is a special technology to ensure that engineering structures are not eroded by water, and plays an important role in civil engineering construction. The quality of waterproofing works directly affects the life of civil engineering. [0003] According to its construction method, waterproof engineering is divided into two categories: structural self-waterproof and flexible waterproof. [0004] 1. Structural waterproofing mainly depends on the compactness of the structural member material itself and some structural measures (slope,...
