Problems solved by technology

Although the migration and precipitation of this organic wood flame retardant has been improved, some flame retardants with a large amount of formaldehyde have actually solved the migration and precipitation problems better than resin-based flame retardants, but this In the process of wood treatment and use, flame retardants will release toxic formaldehyde and pollute the environment
In addition, this type of flame retardant often needs to heat the treated material to a higher temperature to promote the fixation of the flame retardant in the wood, which is easy to cause acid degradation of the wood and damage the physical and mechanical properties of the wood.

Abstract

A fire retardant for wood is proportionally prepared from amino compounds, P contained compound, alcohol compound, boron compounds, aldehyde compounds and water. It has also the anticorrosion and insect-proof functions.

Description

technical field [0001] The invention relates to a fire retardant for wood and a preparation method thereof, belonging to the technical field of wood processing or preservation. Background technique [0002] Wood is a natural biological material and an important raw material for human survival and development. It is widely used in industrial and civil construction, furniture, decoration and other industries. However, wood itself is flammable and is prone to fire when exposed to fire or high temperature. The resulting losses are immeasurable. my country's annual wood consumption is nearly 100 million cubic meters, of which more than 70% are used as furniture and decorative materials. If only 3% of the latter are flame-retardant treated, that is, the production of flame-retardant wood is 2.1 million cubic meters per year. 84,000 tons of flame retardants are needed, therefore, the domestic market for flame retardants is huge. [0003] At present, the wood flame retardants commo...
