[0004] Traditional interior wall coatings such as latex paint have the characteristics of good decorative effect, low cost, and convenient construction. However, because the paint film itself is loose and has air permeability, it cannot form a really dense paint film, let alone shield it from the wall construction. Radon gas diffusion in materials

Abstract
The invention discloses a water-based radon-proof interior wall coating, which consists of a component A and a component B. The component A comprises 12 to 20 mass parts of water, 20 to 25 mass parts of pigment, 50 to 60 mass parts of water-based epoxy resin emulsion and 0 to 2 mass parts of water-based color paste; and the component B comprises 20 to 30 mass parts of water-based curing agent, 50 to 60 mass parts of filler and 15 to 25 mass parts of water. The water-based radon-proof interior wall coating can form a dense physical paint film. The paint film has high radioresistance, and can effectively avoid the harm of radon in the wall to human bodies. The coating has the advantages of scrub resistance and stain resistance. Various colors of the coatings can be obtained by adding different color paste and adjusting the using amount of raw materials; and decorative effects such as highlighting, mercerizing, mattifying and the like can be obtained as required to meet different requirements of interior decoration. The coating can be stably stored for a long time so as to reduce the influence of transportation and storage on product quality and ensure the reliability of the product quality.
Description
technical field [0001] The invention relates to a water-based interior wall paint, in particular to a water-based radon-proof interior wall paint. Background technique [0002] Radon gas is the only gaseous radioactive element that humans come into contact with. It is colorless, odorless, and difficult to be detected by humans. Because radon is a radioactive gas, when people inhale it, the α particles produced by the radon decay process can cause radiation damage in the human respiratory system and induce lung cancer. It is the second largest factor causing lung cancer besides smoking. ) was announced as one of the 19 major environmental carcinogens. In 1987, radon was listed as an important indoor carcinogen by the International Agency for Research on Cancer. [0003] Interior wall paint mainly plays a decorative role, and the particularity of its application makes it necessary to pay attention to the construction and decoration of the paint. The coatings prepared with e...
