Abstract

The invention discloses an environment-friendly flame retardant for wood and a preparation method and an application thereof and belongs to the technical field of flame retardants. Raw materials of the environment-friendly flame retardant for wood are prepared from the following components in parts by weight: 30-50 parts of triethyl phosphate, 20-25 parts of polyvinyl alcohol, 5-10 parts of dextrin, 5-10 parts of acetic ether and 0.2-0.6 part of magnesium chloride. The preparation method comprises the following steps: pre-mixing triethyl phosphate, polyvinyl alcohol and dextrin in a reaction kettle to prepare a premixed material; and pouring the premixed material, acetic ether and magnesium chloride into a stirrer to obtain the environment-friendly flame retardant for wood. By creatively introducing polyvinyl alcohol and dextrin based on a conventional triethyl phosphate material, the flame retardant property of the triethyl phosphate material can be improved by combined use of polyvinyl alcohol and dextrin, and the smoke density index and the oxygen index of the triethyl phosphate material are superior to those in the prior art; meanwhile, the raw materials (except triethyl phosphate) in a formula of the flame retardant are lowly toxic or non-toxic substances, so that the damage of triethyl phosphate flame retardants to human health is reduced.

Description

technical field [0001] The invention belongs to the field of flame retardants, and in particular relates to an environmentally friendly flame retardant for wood and its preparation method and application. Background technique [0002] Wood and its products are a kind of natural polymer materials with excellent performance, especially with the advantages of natural and beautiful texture, temperature and humidity adjustment, etc., they are widely used in interior decoration, furniture manufacturing, house construction and exterior decoration. However, because wood is a flammable material, the requirements for fire protection are more stringent; for example, the main material of furniture is mostly wood, and some wood furniture is covered with cloth or leather, but whether it is wood, cloth or leather is flammable. Once a fire breaks out, it is difficult to escape, which poses a great threat to the safety of users' lives and properties. Wood flame retardants are additives that...
