Abstract

The invention provides a composite wood fire retardant for teaching toys, belonging to the technical field of fire retardants. In the flame retardant of the invention, epoxy resin coated ammonium polyphosphate integrates a carbon source and an acid source into one, so the compatibility between the flame retardant and a polymer matrix is improved; a carbon formation promoter improves the carbon formation speed and the carbon formation amount of the flame retardant, so high flame retardant efficiency is obtained; metal compounds consisting of magnesium hydroxide, aluminum hydroxide and ultrafinezinc borate are used as inorganic flame retardants and have the advantages of no toxicity, no harm and no smoke, and through synergism with other components, flame retardant efficiency is improved, the amount of smoke exhausted during the combustion of the flame retardant is reduced, the flammability of the flame retardant is suppressed, and the flame retardant is allowed to only undergo carbonization and not to burn when taking effect. The wood flame retardant of the invention has good flame retarding effect, no toxicity, no smoke, no harm to environment and human beings and good stability.

Description

technical field [0001] The invention relates to a composition of a fire retardant, in particular to a composition of a composite wood fire retardant for educational toys, and belongs to the technical field of fire retardants. Background technique [0002] Teaching toys are toys used in conjunction with teaching. They are mainly used in kindergartens, primary and secondary school labor skills classes, experimental classes and extracurricular sports activities. The material is mainly composite wood. [0003] Due to the excessive use of wood by humans, the number of wood is getting smaller and smaller, so artificial composite wood has emerged as the times require. Composite wood boards have a low ignition point and are flammable materials, and the requirements for people's fire protection are more stringent. Composite wood flame retardant is an additive that prevents wood from being ignited and inhibits flame propagation, and has a wide range of applications. However, the exi...
