Problems solved by technology

However, inorganic pigments are pigments extracted from minerals, which contain chemical elements such as selenium, cadmium, and chromium. If the human body takes a long-term intake or works in such an environment for a long time, elements such as selenium and cadmium can easily enter through the respiratory tract or skin. Human blood, resulting in the absence or failure of human mechanisms

Abstract

The invention provides a transparent solvent-free single-component waterproof paint and a preparation method thereof. The transparent solvent-free single-component waterproof paint comprises the following raw materials in parts by weight: 30-45 parts of combined polyether polyol, 10-20 parts of isocyanate, 0.01-0.02 parts of a polymerization inhibitor, 10-20 parts of a plasticizer, 0.1-0.2 parts of a wetting dispersant, 0.04-0.08 parts of a catalyst, and 0.1-0.3 parts of a carbon dioxide inhibitor. According to the invention, the environmental protection raw materials substitute toxic solvents, a reaction-type antifoaming agent is employed for preparing the high-solid content environment-friendly type transparent solvent-free single-component waterproof paint, and the waterproof paint has the advantages of excellent coating performance, low cost, safety, environmental protection, and non pollution.

Description

technical field [0001] The invention relates to a transparent one-component polyurethane waterproof coating and a preparation method thereof. Background technique [0002] The transparent one-component polyurethane waterproof coating is made of polyether polyol and isocyanate as the main raw materials together with special additives and plasticizers through polymerization reaction. After the coating is painted, it reacts with moisture in the environment to form a layer Tough, seam-free waterproof protective film with excellent comprehensive performance. Because of its advantages of simple construction and good mechanical properties, it has become the development direction of polyurethane waterproof coatings. [0003] The transparent one-component polyurethane waterproof coating is still blank in China. The bottleneck encountered is how to make the film without air bubbles and make its mechanical properties meet the requirements of the national standard; secondly, the cost i...
