High-crack-resistance building waterproof material and preparation method thereof

Abstract

The invention discloses a high-crack-resistance building waterproof material and a preparation method thereof. The high-crack-resistance building waterproof material is prepared from the following raw materials in parts by weight: 30-50 parts of polyether tribasic alcohol, 10-15 parts of petroleum asphalt, 5-10 parts of fluorocarbon resin, 8-15 parts of nano magnesium oxide, 12-15 parts of organic silicon modified epoxy resin, 12-18 parts of aluminum potassium sulfate dodecahydrate, 15-25 parts of hydroxyethyl cellulose, 4-9 parts of Portland cement, 10-20 parts of talcum powder, 2-10 parts of polyoxyethylene, 1-8 parts of magnesium stearate, 11-17 parts of acrylate, 2-8 parts of steel slag micropowder and 1-8 parts of trimethyl trimellitate. The high-crack-resistance building waterproof material integrates the heat-insulating property and waterproofness, has the advantages of higher compression resistance, long service life, favorable high-temperature resistance, certain elongation percentage, high crack resistance, low cost, favorable binding property, low oxidation and aging tendency, high tensile strength, favorable waterproof effect and the like, can form a waterproof layer on the object surface to effectively avoid the object oxidation, and can be used as a waterproof material for interior architecture. The high-crack-resistance building waterproof material has the advantages of simple formula, low cost and favorable properties, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a building waterproof material with good crack resistance and a preparation method thereof. Background technique [0002] At present, the waterproofing of various buildings is a key issue. Commonly used waterproof materials are various types of waterproof membranes, waterproof coatings, waterproof cement, etc. Waterproof membranes are generally hot construction, mostly baked by fire, the main disadvantage is that the bonding is not comprehensive, there are seams, and some special parts, such as corners, nozzles, etc. Not easy to repair. Waterproof coatings are usually applied cold. After the waterproof coating is mixed well, it can be painted at one time. There is no joint construction and strong adhesion. Its shortcomings are that its strength is not high, and its self-protection is not strong; and the function of this waterproof material is relatively ...

AI Technical Summary

Problems solved by technology

Its disadvantages are that the strength is not high, and the self-protection is not strong; and the function of this waterproof material is relatively single, which directly affects the quality of the building and the service life of the building to a large extent.

[0004] At present, the waterproof materials used are relatively poor in aging resistance, puncture resistance, and corrosion resistance, and the tensile and tear strength cannot be guaranteed, and the adhesive properties of building materials are poor.
