Embodiment 1

[0015] Embodiment 1: An exterior wall waterproof material, which includes liquid material and powder material, wherein the liquid material is vinyl acetate-ethylene copolymer emulsion, and the dosage is: 400 kg. The powder materials are: Portland cement, quartz sand, plasticizer and penetrant, of which: Portland cement 400 kg, quartz sand 550 kg, fineness 200 mesh, plasticizer 25 kg, penetrant 25 kg . Wherein the plasticizer is: sodium sulfate. The penetrant is made of sodium nitrate, sodium carbonate, sodium sulfate, potassium oxide, calcium carbide and limestone in the following weight ratio: 1:1:1:2:2:2. The specific operation is: first pour 400 kg of emulsion into the bucket, use an electric mixer, and slowly add the powder material while stirring. Do not add the powder material at one time, so as to avoid the material at the bottom of the bucket from being mixed thoroughly. Thick, sticky, no agglomeration is the degree. If the paint is too thick when stirring, you can ...

Embodiment 2

[0017] Embodiment 2: An exterior wall waterproof material, which includes liquid material and powder material, wherein the liquid material is vinyl acetate-ethylene copolymer emulsion, and the dosage is: 555 kg. The powder materials are: Portland cement, quartz sand, plasticizer and penetrant, of which: 450 kg of Portland cement, 600 kg of quartz sand, fineness of 200 mesh, 30 kg of plasticizer, and 30 kg of penetrant . Among them, Portland cement is used as the cementitious material, and the plasticizer is sodium sulfate. The penetrant is made of sodium nitrate, sodium carbonate, sodium sulfate, potassium oxide, calcium carbide and limestone in the following weight ratio: 1:1:1:1:1:1.5. The specific operation is: first pour 555 kg of emulsion into the bucket, use an electric mixer, and slowly add the powder material while stirring. Do not add the powder material at one time, so as to avoid the material at the bottom of the bucket from being mixed thoroughly. Thick, sticky, ...

Embodiment 3

[0018] Embodiment 3: An exterior wall waterproof material, which includes liquid material and powder material, wherein the liquid material is vinyl acetate-ethylene copolymer emulsion, and the dosage is: 560 kg. The powder materials are: Portland cement, quartz sand, plasticizer and penetrant, of which: 680 kg of Portland cement, 920 kg of quartz sand, fineness of 250 mesh, 40 kg of plasticizer, and 40 kg of penetrant . The penetrant is made of sodium nitrate, sodium carbonate, sodium sulfate, potassium oxide, calcium carbide and limestone in the following weight ratio: 1:1:1:2:3:2.5. The specific operation is: first pour 560 kg of emulsion into the bucket, use an electric mixer, and slowly add the powder material while stirring. Do not add the powder material at one time, so as to avoid the material at the bottom of the bucket from being mixed thoroughly. Thick, sticky, no agglomeration is the degree. If the paint is too thick when stirring, you can add an appropriate amoun...

Abstract

The invention discloses an exterior wall waterproof material, comprising liquid material and powder material. The weight ratio of the liquid material to the powder material is 1:(2-4); the liquid material is vinyl acetate-ethylene copolymer emulsion; the powder material is made with Portland cement, quartz sand, plasticizer and penetrant according to the weight ratio: (15-18):(20-24):1:1. The exterior wall waterproof material is both rigid and flexible and has the advantages of both the rigid material and the flexible material; added with various unique material compositions and active factors, the exterior wall waterproof material is excellent in waterproofing and impervious performances, is resistant to high and low temperatures, ageing resistant, high in weatherability, nontoxic and odorless and green, allows double waterproofing by single construction, is resistant to long-term soaking, and has certain anticorrosion effect; during construction, the exterior wall waterproof material is rarely destructed, water leakage rarely occurs even if a waterproof layer is destructed, water channeling or water leakage never occurs even if a base layer is severely damaged, a leak point is easy to locate, and local repairing is required only.

Description

technical field [0001] The invention relates to a building material, in particular to an exterior wall waterproof material. Background technique [0002] In the past 10 years, China has entered a period of rapid growth in construction. Construction sites are everywhere in the country. However, due to various reasons, construction leakage occurs frequently. According to CCTV information, the national leakage rate is as high as 80%. At the beginning of the project, various manufacturers, including large and small waterproof manufacturers, talked about how good their materials were, but in the later stages of the project site, serious leakage occurred, resulting in frequent occurrences of buck-passing and lawsuits in the later stages. At present, the most widely used waterproof materials in China's domestic projects are various coiled materials and polypropylene fiber. The leakage is very serious. There are many reasons for the leakage, such as the settlement of the sit...
