Abstract

The invention discloses a universal waterproof coating which is composed of 60-70% by weight of powder materials and 30-40% by weight of liquid materials. The powder materials comprise, by weight, 60-80 parts of ordinary Portland 42.5R cement, 10-20 parts of coarse quartz sand, 10-20 parts of fine quartz powder, 0.2-0.6 part of short glass fiber chopped strips, 0.1-0.4 part of calcium formate, 0.1-0.4 part of a water repellent and 0.5-2 parts of a water reducer; and the liquid materials comprise, by weight, 30-40 parts of an acrylic emulsion, 60-70 parts of distilled water, 0.1-0.5 part of a preservative and 0.01-0.03 part of a defoamer. The universal waterproof coating has the following beneficial effects that water tolerance, weather resistance and ageing-resistant performance of the waterproof coating are enhanced; the waterproof coating has the same service life with the concrete; the waterproof coating can permeate into pores of a substrate in a use process to block the pores, without phenomena of leakage or unstable fastness; the waterproof coating is non-toxic and environment-friendly; and the cost of raw materials is low.

Description

technical field [0001] The invention relates to a general-purpose waterproof paint and belongs to the technical field of building materials. Background technique [0002] There are two types of waterproof materials on the market: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. The tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in my country in 2000. The polyurethane waterproof coating that is still on sale uses asphalt instead of coal tar as a raw material. However, when using this kind of coating, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity; the other type is polymer cement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibility of the polymer (resin) and the rigidity of the cement are integrated, making it e...
