Abstract

The invention relates to a diatom ooze coating special for underground space and preparation and application thereof. The coating is prepared by taking a polymer as a main film forming substance, water as a solvent, diatom ooze and the like as fillings and adding other addition agents. The coating takes the water as the solvent, so the coating has no toxicity and resistance to ultraviolet radiation, can generate negative oxygen ions, has high adhesive strength, good waterproof and quake-proof effects and moderate cost, and is widely used for decorating the inner walls of buildings such as office buildings, residential buildings, hospitals, schools, factory buildings, markets, and entertainment places; the coating has high adhesive strength, good effects of water resistance and permeability resistance, thermal resistance, frost resistance and good extensibility; the coating is performed cold construction, is directly painted, and is operated conveniently; and the coating is applicable to the water resistance, permeability resistance and moisture resistance of various buildings such as new and old roofs, basements, toilets, grain warehouse, dams, oil warehouses, pipelines, swimming pools, tunnels, construction gaps, expansion joints, roads and bridges and the like.

Description

technical field [0001] The invention belongs to the field of waterproof paint and its preparation and application, in particular to a special diatom mud paint for underground space and its preparation and application. Background technique [0002] Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. Used for roof waterproofing, it is easy to cause aging, cracking, deformation, breaking, delamination and other phenomena. It is used for indoor waterproofing. For places with complex shapes, it is difficult to construct, and it is even more difficult to guarantee the quality of leakage. People spend a lot of money and labor on rework every few years. It not only disrupts people's normal life, work and production order, but also directly affects the service life of the entire building. [0003] At present, there are many kinds of waterproof coat...
