Abstract

The invention discloses a sterilization and smoke suppression halogen-free wood fire retardant. The sterilization and smoke suppression halogen-free wood fire retardant is composed of, by mass, 40-80 parts of guanyl urea phosphate, 30-50 parts of urea, 10-20 parts of zinc borate, 5-10 parts of ammonium molybdate, 3-10 parts of pentaerythritol, 1-20 parts of ammonium dihydrogen phosphate, 12-25 parts of silica sol, 3-15 parts of decabromodiphenyl ether, 5-10 parts of fatty alcohol-polyoxyethylene ether, 1-20 parts of hexadecyltrimethoxysilane, and 1-20 parts of nanometer titania modified by one of Pt, Ag and Fe<3+>. The sterilization and smoke suppression halogen-free wood fire retardant is good in flame retardant property, high in anti-moisture absorption property and leaching resistance, good in stability, completely non-poisonous and low in cost and has the smoke suppression and sterilization effects.

Description

Technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to a sterilization and smoke-suppressing halogen-free wood flame retardant. Background technique [0002] Wood is an ideal material for construction, furniture and interior decoration, but its flammability limits its use. Wood flame retardant is a kind of mechanism that promotes the formation of charcoal, forms an isolation layer, releases incombustible gases, terminates free radical reactions, and absorbs combustion heat. It makes wood flammable and becomes non-combustible, which greatly increases the safety of wood. Sex. [0003] At present, wood flame retardants are mainly composed of halogen and its compound flame retardants, metal hydroxide flame retardants, phosphorus-based halogen-free flame retardants, boron-based flame retardants, phenolic flame retardants, FRW flame retardants, etc. Halogen and its compound flame retardants are rarely used because they produce...
