Problems solved by technology

[0004] At present, the quality of flame retardants on the market is uneven, and the price of good flame retardant effect is high. On the contrary, the flame retardant effect of cheap ones cannot meet the requirements. If the flame retardant is directly compounded with soybean gum, there will be Problems such as fast glue drying, cold pressing without forming, finished product wet strength and impregnation peeling are unqualified, etc.
The formaldehyde-free flame-retardant glue disclosed in the patent application number CN201910843380.8 was used to trial-produce solid wood composite flooring. The test results showed that the flame-retardant grade and formaldehyde emission were all qualified, but the type II bonding strength was only 0.3-0.4MPa and the dipping peeling was unqualified. , not for parquet

Description

technical field [0001] The invention relates to the technical field of production and processing of solid wood composite flooring, in particular to a modified soybean formaldehyde-free flame-retardant glue and a preparation method thereof. Background technique [0002] Wood flooring is a commonly used ground decoration material. The main varieties include laminate flooring, solid wood composite flooring, solid wood flooring, and impregnated paper laminate veneer multi-layer solid wood composite flooring. Compared with other ground decoration materials such as carpet, stone, ceramic tile, and plastic floor, wooden floor has natural and beautiful texture, light weight and easy processing, good heat preservation, can adjust indoor temperature and humidity, and has the characteristics of being elastic and shock-relieving. It gives people a feeling of returning to nature, so it is loved by people. The solid wood composite floor occupies a dominant position in the wooden floor pr...
