Heat-insulated composite waterproof material for buildings and preparation method thereof

Abstract

The invention discloses a heat-insulated composite waterproof material for buildings and a preparation method thereof. The heat-insulated composite waterproof material is prepared from the following materials in parts by weight: 30-50 parts of polyether-tribasic alcohol, 10-15 parts of petroleum resin, 5-10 parts of fluorocarbon resin, 8-15 parts of nanometer magnesium oxide, 12-15 parts of organosilicon-modified epoxy resin, 12-18 parts of aluminum potassium sulfate dodecahydrate, 15-25 parts of synthetic rubber, 4-9 parts of wood fiber, 10-20 parts of talcum powder, 2-10 parts of polyvinyl alcohol, 1-8 parts of methyl silicone oil, 11-17 parts of acrylic ester, 2-8 parts of wood flour and 1-8 parts of trimethyl trimellitate. According to the heat-insulated composite waterproof material and the preparation method disclosed by the invention, the heat-insulated property and the waterproof property are integrated, the compression strength is stronger, the service life is long, the high-temperature resistance is excellent, certain elongation is achieved, the cracking resistance is strong, a waterproof layer is formed on the surface of an object, the oxidation of the object can be effectively avoided, the cost is low, the bonding property is good, the oxidation and the ageing are not easy, the tensile strength is high and the waterproof effect is good and the like; the heat-insulated composite waterproof material can be used as a waterproof material for indoor buildings, adopts a simple formula, is low in cost and excellent in property 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 heat-insulating composite waterproof material for building 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 relative...

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.
