A kind of low-aldehyde impregnated film paper veneer wood-based panel and its preparation method
A technology for impregnating adhesive film paper and wood-based panels, which is applied in the direction of chemical instruments and methods, paper/cardboard layered products, manufacturing tools, etc., and can solve the problems of low glue hanging, unreachable gloss and fullness, and scratch resistance of decorative paper. Poor rubbing performance and other problems, to solve the problem of damage between papers, shorten the impregnation time, and achieve the effect of high physical properties

Embodiment 1
[0032] 1) Add all the pH regulator and deionized water, 1 / 3 soft monomer, 1 / 3 hard monomer, 1 / 3 initiator and all emulsifiers into the reactor, the stirring blade is at an angle of 50° to the horizontal plane, and the paddle The height from the leaf to the bottom of the reaction vessel is 1 / 2 of the liquid level, the stirring speed is 200r / min, and the reaction is stopped immediately after the bluish light is turned to prepare the pre-emulsion.
[0033] 2) Mix the remaining amount of soft monomer and hard monomer evenly, add dropwise to the pre-emulsion with the remaining amount of initiator at 85°C, raise the temperature to 85°C under stirring, and stir at a speed of 150r / min After 30 minutes of dripping, keep the stirring paddle at an angle of 50° to the horizontal plane during the dropping process, and the height between the paddle and the bottom of the reaction vessel is 1 / 2 of the liquid level. After the dropping is completed, keep warm for 20 minutes to prepare a water-ba...

[0044] 1) Add all the pH regulator and deionized water, 1 / 3 soft monomer, 1 / 3 hard monomer, 1 / 3 initiator and all emulsifiers into the reactor, the stirring blade is at an angle of 60° to the horizontal plane, and the paddle The height between the leaves and the bottom of the reaction vessel is 1 / 3 of the liquid level, the stirring speed is 150r / min, and the reaction is stopped immediately after the bluish light is turned to prepare the pre-emulsion.
[0045] 2) Mix the remaining amount of soft monomer and hard monomer evenly, add dropwise to the pre-emulsion with the remaining amount of initiator at 85°C, raise the temperature to 85°C under stirring, and stir at a speed of 100r / min After 30 minutes of dripping, keep the stirring paddle at an angle of 60° to the horizontal plane during the dropping process, and the height between the paddle and the bottom of the reaction vessel is 1 / 3 of the liquid level. After the dropping, keep warm for 30 minutes to prepare a water-based acr...
Embodiment 3
[0056] 1) Add all the pH regulator and deionized water, 1 / 3 soft monomer, 1 / 3 hard monomer, 1 / 3 initiator and all emulsifiers into the reactor, the stirring blade is at an angle of 50° to the horizontal plane, and the paddle The height between the leaf and the bottom of the reaction vessel is 1 / 2 of the liquid level, the stirring speed is 180r / min, and the reaction is stopped immediately after the bluish light is turned to prepare the pre-emulsion.
[0057] 2) Mix the remaining amount of soft monomer and hard monomer evenly, add dropwise to the pre-emulsion with the remaining amount of initiator at 85°C, raise the temperature to 85°C under stirring, and stir at a speed of 120r / min After 30 minutes of dripping, keep the stirring paddle at an angle of 50° to the horizontal plane during the dropping process, and the height between the paddle and the bottom of the reaction vessel is 1 / 2 of the liquid level. After the dropping is completed, keep warm for 20 minutes to prepare a wate...
