Problems solved by technology

However, since the floor, especially the solid wood composite floor, is made of multiple pieces of wood boards bonded by adhesives, under long-term heating conditions, the adhesive force of the adhesives is likely to decrease, and the boards are degummed and warped.
On the other hand, due to the poor performance of the existing adhesives and waterproofing agents, the waterproof effect of the existing electric heating floor is not satisfactory, and the waterproof performance is a very important indicator for the electric heating floor. Water is extremely easy to cause safety accidents

Abstract

The invention discloses a new material for electric heating parquet with a built-in heating layer. The new material contains melamine modified urea-formaldehyde resin adhesive bonded with carbon fiber paper. A preparing method for the melamine modified urea-formaldehyde resin adhesive includes the following steps that 1, polyamide is prepared, wherein an appropriate amount of water is added into 30-40 parts of diethylenetriamine, the mixture is stirred, 40-50 parts of hexanedioic acid are added in the stirring process, after stirring is conducted for 30 min, temperature is uniformly raised to 150 DEG C-170 DEG C within 1-5 h, kept for 15 min and then lowered to 80 DEG C-120 DEG C, an appropriate amount of water is added for cooling, and the mixture is heated to 80 DEG C-120 DEG C again and uniformly stirred to obtain polyamide; 2, the pH value of 40-60 parts of a formaldehyde solution is adjusted to 9.5, then 15-30 parts of urea are added, the mixed solution is heated to 85 DEG C-95 DEG C to react for 40-60 min, the pH value is adjusted to 5, after the sufficient reaction, 10-20 parts of polyamide and 20-30 parts of melamine are added, 5-10 parts of epoxy chloropropane are added dropwise, and all the substances react while stirred so that melamine modified urea-formaldehyde resin adhesive can be obtained after the reaction is finished.

Description

technical field [0001] The invention relates to a material for a solid wood composite floor, in particular to a material for an electric heating solid wood composite floor with a built-in heating layer, and belongs to the technical field of electric heating floors. Background technique [0002] As we all know, flooring has gradually become a necessity for home decoration and has entered most families due to its very practical functions such as moisture insulation, cold resistance, and comfort. With the continuous improvement of people's living standards, the use function of the floor is also continuously improved. In order to solve the problem of heating in winter, more and more families use electric heating floors that can generate heat for heating. However, since the floor, especially the solid wood composite floor, is made of multiple wood boards bonded by adhesives, in a long-term heating state, the adhesive force of the adhesives is likely to decrease, and the problem ...
