Phosphorus and nitrogen synergistic self-flame retardant environment-friendly wood coating

Abstract

The invention discloses phosphorus and nitrogen synergistic self-flame retardant environment-friendly wood coating. The phosphorus and nitrogen synergistic self-flame retardant environment-friendly wood coating is prepared from the following components is percentage by weight: 35.0 to 70.0 percent of acrylic emulsion containing phosphorus nitrogen flame retardant groups, 0.5 to 5.0 percent of a dispersing agent, 0.2 to 2.0 percent of a pH regulating agent, 0.1 to 0.5 percent of a defoaming agent, 0.1 to 0.5 percent of a thickening rheological agent, 2.0 to 15.0 percent of a coalescing agent, 0to 5.0 percent of water-based colour paste, 0 to 10.0 percent of other functional auxiliary agents, 0.1 to 0.5 percent of a sterilizing agent, 10.0 to 25.0 percent of deionized water and 5.0 to 30.0percent of filler. The phosphorus and nitrogen synergistic self-flame retardant environment-friendly wood coating takes the acrylic emulsion containing the phosphorus nitrogen flame retardant groups as a main component of a base material of the coating, so that the coating can have self-flame retardance without adding other flame retardants; flame-retardant phosphorus and nitrogen elements and theacrylic resin are bonded through chemical bonds and are difficult to dissociate, so that the coating has lasting flame retardance; the phosphorus and nitrogen synergistic self-flame retardant environment-friendly wood coating does not contain any halogen, is harmless to human bodies, and is healthy and environmentally friendly.

Description

technical field [0001] The invention relates to a phosphorus-nitrogen synergistic self-flame-retardant environmental protection coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] Although a variety of new building structure materials and decorative materials have been developed and produced in the world today, due to the unique and excellent characteristics of wood, wood veneer gives people a special and beautiful look and feel, which cannot be compared with other decorative materials. of. Therefore, wood has always maintained an important position in construction engineering, especially in the field of decoration. Due to the large amount of building materials used, it directly affects the cost of the project. Usually, the cost of building materials accounts for more than half of the total cost of the project. Therefore, when considering technical performance, economical efficiency must be taken into account. But...

Problems solved by technology

However, the coating of this invention uses antimony trioxide as a flame retardant, which not only has the disadvantage of uneven dispersion, but also antimony trioxide will continue to dissociate to the surface of the coating during the use of the coating, resulting in a continuous decrease in flame retardancy.
