Problems solved by technology

The styrene-butadiene rubber sealing adhesive tape has a short service life, is easy to age, and is easy to leak
However, silicone glue has low bonding strength after solidification and is easy to age. There are many hidden dangers in the construction process, and the waterproof quality is unreliable and easy to leak.
[0007] Therefore, these materials cannot be used in the waterproof field of metal roofs for a long time.

Abstract

The invention relates to a special metal roofing organo-silicone rubber waterproof paint and a preparation method thereof. The paint is prepared from water, organo-silicone rubber emulsion, sodium lauryl benzenesulfate emulsion, phthalic acid, emulsifier, dispersant, sodium chloride, vinyl acetate, isooctyl alcohol, bentonite, heavy calcium carbonate, aedelforsite, ferric oxide, nano silicon dioxide, pigment and defoamer. The paint is nontoxic and tasteless and is ultraviolet radiation resistant, ageing resistant, waterproof, anticorrosion, thermally insulated, environment-friendly and energy-saving; therefore, the paint is suitable for metal roofing of workshops and factories, and the paint has special waterproofing effect as for important waterproofing complicated roofs.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a special silicone rubber waterproof coating for metal roofs and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Metal roofing is one of the fastest growing segments of the roofing market, especially for residential applications. The construction industry expects aesthetics and longevity from metal roofing materials. [0003] For the waterproof treatment of the metal roof, it should be changed according to the temperature difference of the environment, and the hidden danger of water leakage is very easy to occur at the interface of the metal plate. In the steel structure system, due to the structure itself under the action of external forces such as temperature changes, wind loads, and snow loads, displacements occur at the joints, resulting in hidden dangers of water leakage, etc., so a waterproof material that is truly s...
