Problems solved by technology

It is painted or sprayed on the surface of the steel structure to play the role of fireproof and heat insulation. The current fireproof coatings use alkyd resin, acrylic acid, epoxy modified resin, chlorinated resin, etc. as binders, and polyphosphate amine, melamine, Pentaerythritol is a fire-resistant coating composed of flame-retardant foaming components, additives, and solvents, such as the fire-resistant coating disclosed by the publication number CN 102408802A. These products have a big disadvantage, that is, in the use of outdoor steel structures, ultra-thin The construction of fire-resistant coatings needs to be painted at least ten times, and the thickness reaches about 2.5mm. During the construction process in different areas, the weather may rain, which requires testing that the coating will be damaged if it rains before it is completely dry. The most important problems are foaming, cracking and peeling, which make the fireproof coating impossible to be applied outdoors. The present invention better solves such problems, so the research on fireproof coating is of great significance, and its market is also very promising

Abstract

The invention relates to an outdoor elastic fireproof paint and a preparation method thereof. The outdoor elastic fireproof paint comprises the following components: an environment-friendly solvent, rubber elastic resin, flame-retardant amino resin, a dispersant, compound foam powder, fine ammonium polyphosphate powder, titanium pigment, melamine powder, a flame retardant aid, wood cellosilk and hollow perlite fillers. By mixing and matching the rubber elastic resin with the flame-retardant amino resin, the outdoor elastic fireproof paint has ultrahigh water resistance and excellent wet adhesion, weather resistance, elasticity and tensile strength, the condition that the construction is canceled because of raining is reduced, a coating cannot be damaged by the washing of rainwater, and the limitation of construction conditions is avoided; by imitating an actual construction process and a long-term raining condition, the paint is brushed three times continuously to obtain a paint coat with the thickness of 900 microns, and the paint coat which is not completely dried cannot be damaged after being washed by rainwater uninterruptedly for five days and five nights; the paint also has chemical resistance, so that the outdoor use and the durability are guaranteed, and the service life of the outdoor elastic fireproof paint is long.

Description

technical field [0001] The invention belongs to the field of paint chemical industry, and in particular relates to an outdoor elastic fireproof paint and a preparation method thereof. Background technique [0002] In recent years, many large-scale fires have occurred, causing huge property losses and casualties, such as the previous Shanghai Jing'an high-rise building, the new CCTV building, etc. Therefore, the country attaches great importance to the fire protection requirements of materials. All fire-fighting products must be strictly tested and certified, and can only be approved for production after meeting the requirements set by the Ministry of Public Security for fire-fighting products. At present, the country has only set up two authoritative inspection institutions - Tianjin Fire Research Institute and Sichuan Dujiangyan Fire Research Institute to conduct quality supervision and inspection of fire protection products. With the large-scale development of urban const...
