Embodiment 2

[0052] The stain-resistant melamine veneer of this embodiment is composed of medium density fiberboard and stain-resistant melamine-impregnated film paper.

[0053] The preparation method of the stain-resistant type melamine veneer of the present embodiment is as follows:

[0054]1) Prepare stain-resistant melamine resin adhesive:

[0055] A. Modify nano-SiO with 15g of KH550 silane coupling agent 2 Disperse in 670g of distilled water, and shake for 1 hour with an ultrasonic crusher to obtain a uniformly dispersed shaking liquid;

[0056] B. After adding 1785g of formaldehyde aqueous solution with a pH value of 4 into a three-necked flask as a reaction kettle, add nano-SiO with a weight of 685g, 70g, and 1000g in turn. 2 Dispersions, Borax and Melamine. Within 40 to 50 minutes, the reactant was heated to 90°C, reacted at 90°C for 1 hour, cooled to 80°C, and reacted at this temperature for 2 hours, then added 4.3 g of sodium hydroxide solution with a purity of 20%. Under th...

[0065] The stain-resistant melamine veneer of this embodiment is composed of medium density fiberboard and stain-resistant melamine-impregnated film paper.

[0066] The preparation method of the stain-resistant type melamine veneer of the present embodiment is as follows:

[0067] 1) Preparation of stain-resistant melamine resin adhesive

[0068] A. Modify nano-SiO with 8g of KH550 silane coupling agent 2 Disperse in 670g of distilled water, and shake for 1 hour with an ultrasonic crusher to obtain a uniformly dispersed shaking liquid;

[0069] B. After adding 1785g of formaldehyde aqueous solution with a pH value of 4 into a three-necked flask as a reaction kettle, add nano-SiO with a weight of 678g, 70g, and 1000g in sequence. 2 Dispersions, Borax and Melamine. Within 40 to 50 minutes, the reactant was heated to 90°C, reacted at 90°C for 1 hour, cooled to 80°C, and reacted at this temperature for 2 hours, then added 4.3 g of sodium hydroxide solution with a purity of 20%....

Abstract

The invention discloses a preparation method for an anti-fouling melamine decorative board, and relates to melamine decorative boards. The preparation method includes the steps: 1, preparation of an anti-fouling melamine resin adhesive; 2, preparation of anti-fouling melamine resin impregnated paper; and 3, preparation of the anti-fouling melamine decorative board. Compared with the prior art, the anti-fouling melamine decorative board has the micro surface more smooth and uniform than that of ordinary melamine decorative boards; the surface energy is relatively low, and the board has good self-cleaning property on surface dust; the board has good anti-fouling effect on osmosis pollution of stamp-pad inks; the board reaches the surface anti-fouling level 1 specified in the national standard ''test methods of evaluating the properties of wood-based boards and surface decorated wood-based boards'' (GB / T17657-2013); in short, a two-time spraying process reduces the production costs under a condition of improving surface characteristics, and also does not affect gluing of impregnated paper and the substrate; and nano SiO2 and a fluorine-containing finishing agent have relatively low costs, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to a melamine veneer, in particular to a method for preparing a stain-resistant melamine veneer. Background technique [0002] The melamine cabinet panel, that is, the melamine veneer, is called the melamine impregnated film paper veneer wood-based panel; the melamine veneer is made of special decorative paper, impregnated with melamine formaldehyde resin, dried to a certain extent, and paved on particleboard, The surface assembly of medium density fiberboard or hard fiberboard is sent into a hot press for hot pressing and curing, and the decorative board is made under a certain temperature and pressure. [0003] Melamine veneer is suitable for the special environment of the kitchen, and more caters to the needs of "beautiful and practical" kitchen cabinets; and has the advantages of smooth surface, not easy to deform and bend, its excellent performance and relatively affordable price, making it popular in the kitchen cabinet indu...
