Embodiment 1

[0062] Preparation of nano silver:

[0063] The sodium dodecyl sulfonate solution is added to the silver nitrate aqueous solution to obtain a mixed solution, and the molar ratio of sodium dodecyl sulfonate and silver nitrate is 2:1;

[0064] The mixture was heated to 45°C, and dicyclohexane-18-crown-6 and sodium borohydride were added to the mixture under stirring, heated to 70°C, and stirred continuously for 5 min; The molar ratio of -6 to silver nitrate is 1:1; the molar ratio of sodium borohydride to silver nitrate is 0.5:1, and the pH value is controlled to be 8 to obtain nano-silver.

[0065] a. Sanding the substrate: Use a three-frame sander to sand the surface of 18mm common poplar plywood, and the third sanding belt is 180 mesh. Measure its thickness error, the maximum error is 0.11mm. Observe its surface finish, the surface is smooth and clean, and there is no wave pattern;

[0066] b. Formaldehyde decomposition glue solution preparation: fully mix the formaldehyde...

Embodiment 2

[0074] Preparation of nano silver:

[0075] The sodium dodecyl sulfonate solution is added to the silver nitrate aqueous solution to obtain a mixed solution, and the molar ratio of sodium dodecyl sulfonate and silver nitrate is 3:1;

[0076] The mixture was heated to 55°C, and dicyclohexane-18-crown-6 and potassium borohydride were added to the mixture under stirring, heated to 85°C, and stirred continuously for 8 min; The molar ratio of -6 to silver nitrate is 2:1; the molar ratio of potassium borohydride to silver nitrate is 1:1, and the pH value is controlled to be 8-9 to obtain nano-silver.

[0077] a. Sanding the substrate or applying veneer: Use a three-sand frame sander to sand the surface of the 16.5mm blockboard core, and the third sanding belt is 200 mesh. Measure its thickness error, the maximum error is 0.22mm. Observe its surface finish, the surface is rough. A layer of poplar veneer with a thickness of 0.5mm is covered on its surface, and the moisture content ...

Embodiment 3

[0086] Preparation of nano silver:

[0087] The sodium dodecyl sulfonate solution is added to the silver nitrate aqueous solution to obtain a mixed solution, and the molar ratio of sodium dodecyl sulfonate to silver nitrate is 2.5:1;

[0088] The mixture was heated to 50°C, and dicyclohexane-18-crown-6 and sodium metaphosphate were added to the mixture under stirring, heated to 75°C, and stirred continuously for 6 min; The molar ratio of -6 to silver nitrate is 1.5:1; the molar ratio of sodium metaphosphate to silver nitrate is 0.8:1, and the pH value is controlled to be 8.5 to obtain nano-silver.

[0089] a. Sanding the substrate: the substrate is blockboard core or plywood; if the surface finish of the blockboard core or ordinary plywood substrate is poor or the thickness error exceeds 0.15mm, the surface needs to be covered with a thickness of 0.7mm, containing water The whole veneer with a rate of ≤5%, the veneer is usually poplar veneer or restructured decorative veneer;...

Abstract

The invention relates to a paint-free decorative overlay fitment board, in particular to a formaldehyde-buster antibacterial ecological board and a manufacturing method thereof, and belongs to wood processing industry. The formaldehyde-buster antibacterial ecological board comprises a base material layer, and an upper surface layer decorative film adhesive paper layer and a lower surface layer decorative film adhesive paper layer which adhere on the upper surface and the lower surface of the base material layer in a pressed mode respectively. The upper and / or lower surface layer decorative film adhesive paper layer are / or decorative paper dipped with an amino resin adhesive solution and a formaldehyde decomposition adhesive solution. The decorative paper dipped with the amino resin adhesive solution and the formaldehyde decomposition adhesive solution is 0.08-0.12 mm thick, and the base material layer is 2.5-25 mm thick. The formaldehyde decomposition adhesive solution comprises formaldehyde decomposition effective constituents, amino resin and nano-silver. The mass of the formaldehyde decomposition effective constituents accounts for 5-10% that of the formaldehyde decomposition adhesive solution. The formaldehyde decomposition effective constituents comprise chitin and nano silicon wafers. The amino resin is melamino-formaldehyde resin or melamine modified urea resin. The concentration of the nano-silver is 50-150 ppm. The formaldehyde-buster antibacterial ecological board is vivid in decoration effect, low in cost and good in formaldehyde-buster antibacterial ecological board purifying effect.

Description

technical field [0001] The invention relates to a paint-free veneer furniture board, in particular to a pure aldehyde antibacterial ecological board and a manufacturing method thereof, belonging to the wood processing industry. Background technique [0002] The status quo of indoor air quality is a focus of social concern. Formaldehyde, TVOC, and bacterial concentrations exceeding the standard seriously affect people's physical and mental health. Ordinary wood-based furniture panels use adhesives synthesized from formaldehyde and urea to achieve the bonding effect. Although the bonding performance is excellent, the formaldehyde released from them causes the indoor air quality to deteriorate, and it breeds health hazards for the elderly, the infirm or pregnant women. Therefore, functional boards that can absorb and decompose formaldehyde in the air are the needs of people's health and the development direction of furniture boards. [0003] The ecological board is based on bl...
