Preparation method of anti-aging waterproof coating

Abstract

The invention mainly relates to the technical field of building material processing, and discloses a preparation method of an anti-aging waterproof coating. The preparation method comprises the following steps: asphalt treatment, primary mixing, secondary mixing and packaging. The preparation method of the anti-aging waterproof coating is simple in process; preparation is convenient; large-scale production can be realized; after smearing of the prepared coating on a cement base surface, natural curing can be realized after being slightly heated; the coating is convenient to use; weather resistance, ultraviolet resistance and chemical corrosion resistance can be achieved after solidification; the service life can be obviously prolonged; the waterproof effect can be kept for a long time; water leakage and repeated maintenance are avoided; maintenance cost is reduced; and unnecessary troubles in life are avoided for consumers.

Description

technical field [0001] The invention mainly relates to the technical field of building material processing, in particular to a preparation method of an aging-resistant waterproof coating. Background technique [0002] Waterproofing has always been a constant topic in the construction industry, because the top floors of buildings, kitchens, bathrooms and balconies are all areas that may be in contact with water in large quantities, which can easily lead to water seepage, which will cause great trouble and distress to people's lives, especially After water seepage in the kitchen and bathroom, the tiles need to be removed and processed, which not only affects life, but also causes damage to the tiles, repeated removal and repair; there are various waterproof coatings on the market, with many brands and uneven quality , Many waterproof coatings have a good waterproof effect when they are just used, but aging and cracking will occur after 3 to 5 years of use, especially the water...

[0002] Waterproofing has always been a constant topic in the construction industry, because the top floors of buildings, kitchens, bathrooms and balconies are all areas that may be in contact with water in large quantities, which can easily lead to water seepage, which will cause great trouble and distress to people's lives, especially After water seepage in the kitchen and bathroom, the tiles need to be removed and processed, which not only affects life, but also causes damage to the tiles, repeated removal and repair; there are various waterproof coatings on the market, with many brands and uneven quality , Many waterproof coatings have a good waterproof effect when they are just used, but aging and cracking will occur after 3 to 5 years of use, especially the waterproof layer of the roof, which is easily exposed to sunlight and temperature changes for a long time. Aging leaks, so repeated repairs are required, resulting in a significant increase in construction costs and maintenance costs, and repeated repairs will also affect the appearance, so an aging-resistant waterproof coating is needed to avoid repeated waterproof repairs

[0003] Existing patent document CN109135569A discloses a kind of manufacturing method of organosilicon-modified asphalt waterproof coating, specifically discloses adding 90# asphalt, 5# naphthenic oil, polyisoprene liquid rubber, styrene- Isoprene-styrene block copolymer particles, carbon five hydrogenated petroleum resin, organic silicon and saponite powder, although the prepared waterproof coating has good waterproof performance, but the aging resistance is not ideal, and it is very difficult after being used on the roof. It is easy to age and crack, and loses its waterproof performance, so it is necessary to provide an aging-resistant waterproof coating
