Problems solved by technology

Solid wood flooring is mostly used for high-end decoration due to its high price, and solid wood composite flooring is mostly used for daily decoration. However, the existing solid wood composite flooring generally has the problem of relatively single structure and function, which cannot meet people's needs; the existing floor is not elastic. , unable to buffer pressure, poor seismic performance, when an external force acts violently on the ground, not only will it produce a loud sound, but it will also damage the floor, causing cracks and dents on the surface of the wooden floor.
In addition, the existing solid wood composite floor has no antibacterial function, and it is easy to accumulate bacteria, which poses a threat to human health; moreover, the existing floor has no flame retardant function, and it is easy to burn in case of fire, causing unimaginable consequences

Embodiment 1

[0008] Before the production of double veneers, we used the cold pressing process of latex white glue. Due to the poor moisture resistance, we could not meet the standard of the first-class board. Now the process is adjusted as follows:

[0009] Double veneer hot pressing process: board core→single-sided middle board→pre-pressing→sand core board→pasting middle board→pre-pressing→opening repair→hot pressing→sanding (1, 2)→sanding (1, 2) 2) → Paste the fireproof board → Pre-press → Hot press → Edge.

[0010] Double veneer glue mixing process: 50kg latex glue, 50kg urea-formaldehyde glue, 25-30kg flour, 2kg ammonium chloride, melamine.

[0011] Take a certain mass ratio of milky white glue and urea-formaldehyde glue, add it to the glue mixing tank and stir for 5-10 minutes; then add a certain mass ratio of flour, ammonium chloride, and melamine, stir for 10-30 minutes, and then it can be used.

[0012] Hot pressing temperature T=85~95℃; gauge pressure p=4MPa; time t=180s.

Abstract

The invention discloses a double-veneer flooring comprising, by mass, 20-70 parts of white latex, 20-70 parts of urea-formaldehyde glue, 10-50 parts of flour, 1-5 parts of ammonium chloride, and 1-5 parts of melamine. According to the invention, processed solid wood flooring has excellent seismic and silencing functions. Floor is effectively protected, and noise is greatly reduced. With the process provided by the invention, the flooring also has flame-retardant and antibacterial functions. The fire prevention performance is greatly improved, and sterilization and deodorization functions are provided, such that human bodies are prevented from bacteria nuisance.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a method for manufacturing a double veneer floor. Background technique [0002] With the advancement of industry and the gradual improvement of people's living standards, people's taste for living environment and decoration is also constantly improving. Wooden flooring is becoming more and more popular in people's life and work. Now it is more common to use solid wood flooring. and parquet floors. Solid wood flooring is mostly used for high-end decoration due to its high price, and solid wood composite flooring is mostly used for daily decoration. However, the existing solid wood composite flooring generally has the problem of relatively single structure and function, which cannot meet people's needs; the existing floor is not elastic. , unable to buffer pressure, poor seismic performance, when an external force acts violently on the ground, it will not only produce a loud sound,...
