Abstract

The present invention relates to wood fire retardant, and is especially one kind of multiple effect wood fire retardant and its preparation process. The multiple effect wood fire retardant is prepared with boric acid, guanyl urea phosphate, ammonium dihydrogen phosphate, water softening agent and anti-mildew agent, and through mixing and drying. Once using the multiple effect wood fire retardant in treating timber can reach the protecting effects of preventing fire, inhibiting smoke, preventing corrosion, preventing moth, etc.

Description

technical field [0001] The invention relates to a wood flame retardant and a preparation method thereof. Background technique [0002] Wood is widely used for its excellent biological and environmental characteristics, but due to its shortcomings such as flammability, perishability, and biodegradability, it must be treated with necessary protection. At present, the protective treatment of wood is mainly realized by multiple treatment processes with various agents. This multiple treatment process will not only reduce the mechanical properties and bonding properties of wood, but also has high treatment costs. Contents of the invention [0003] The present invention solves the problems of high processing costs and affecting the mechanical properties and gluing properties of wood in the prior art in order to achieve multiple protective effects such as flame retardant, anti-corrosion, and insect-proof by using multiple treatments of multiple agents for wood. A multi-effect woo...
