Problems solved by technology

However, the resin is prone to aging and cracks on the surface under severe outdoor temperature and humidity conditions for a long time, causing corrosive gases such as oxygen in the air and water vapor to enter and cause erosion, causing the surface of the decorative board to fade, yellow, and fade. uneven color
Significantly shortens the service life of the trim panels

preparation example Construction

[0050] The preparation method of the fluoroalkylsilane resin composite resin comprises the following steps: heating the fluoroalkylsilane resin as the raw material required in a stainless steel reactor to 65°C (the heating rate is 1°C / min), and then heating the fluoroalkylsilane resin at 65°C Add the cross-linking agent and end-capping agent while stirring under the conditions, continue to keep warm and stir for 20 minutes after complete addition, after the stirring is completed, lower the temperature to 45-50°C and discharge the material to obtain the fluoroalkylsilane resin composite resin.

[0051] Add silicon dioxide particles with a particle size of 10 to 20 nm to the fluoroalkylsilane resin composite resin to obtain the fluoroalkylsilane resin composite resin with silicon dioxide, stir it evenly for use, and add silicon dioxide The mass percent content of silicon dioxide in the fluoroalkylsilane resin composite resin is 25%.

[0052] The fluoroalkylsilane resin (purchase...

Embodiment 1

[0072] A kind of non-contamination and non-finger mark high-pressure decorative board, such as figure 1 As shown, the decorative board includes a balance layer 1, and a substrate layer 2, an adhesive layer 3, and a non-contaminated and non-fingerprint decorative layer 4 sequentially arranged on the balance layer from the bottom right to the top;

[0073] The balance layer 1 is wood pulp kraft paper impregnated with thermosetting water-soluble phenolic resin, and the back of the wood pulp kraft paper impregnated with thermosetting water-soluble phenolic resin is coated with a thermosetting melamine formaldehyde resin layer (that is, the side opposite to the substrate layer) , the thickness of the coated thermosetting melamine formaldehyde resin is 0.01mm; the thickness of the obtained balance layer is 0.1-0.2mm;

[0074] The substrate layer 2 is wood pulp kraft paper impregnated with thermosetting water-soluble phenolic resin, and the thickness of each layer of kraft paper is 0...

Embodiment 2

[0081] One of the preparation methods of a non-contamination and finger-mark-free high-pressure decorative board, the method comprises the following steps:

[0082] (1) Preparation of balance layer

[0083] Quantitatively 100g / m 2 The wood pulp kraft paper is impregnated with thermosetting water-soluble phenolic resin, dried, and then coated with a thermosetting melamine-formaldehyde resin layer on its back, and dried again, and the balance layer can be obtained after cutting;

[0084] The weight of the wood pulp kraft paper is 70%, and the volatile matter is 8.0%;

[0085] (2) Preparation of substrate layer

[0086] Quantitatively 100g / m 2 The wood pulp kraft paper is impregnated with thermosetting water-soluble phenolic resin and dried, and the substrate layer can be obtained after cutting;

[0087] After dipping, the amount of gluing is 50%, and the volatile matter is 7.5%;

[0088] (3) Preparation of adhesive layer

[0089] Quantitatively 18g / m 2 The surface paper i...

Abstract

The invention discloses a non-staining non-finger mark high-pressure decorative board and a preparation method thereof. The high-pressure decorative board is formed by a balance layer, a substrate layer, an adhesive layer and a non-staining non-finger mark decorative layer through high-temperature and high-pressure moulding. The non-staining non-finger mark decorative layer is a resin-coated decorative paper, the decorative paper is coated with the fluoroalkylsilane resin composite resin with addition of silica particles. The mass percentage of the silica particles in the composite resin is 20% to 30%, and the particle size is 10 to 20 nm. The obtained high-pressure decorative board forms a protective film with high pollution resistance, fingerprint staining resistance and graffiti resistance, and has strong anti-adhesion property; can effectively block the damage of the decorative layer by ultraviolet rays and oxygen, acid corrosive gas, water vapor, and the like, and can keep the good stability of the decorative effect of the decorative board for a long time. Therefore, the decorative board can be better used for exterior wall decoration, beach tables and chairs, outdoor furniture decoration, and the like, can better protect the decorative objects from damage, which greatly expands the decorative board.

Description

technical field [0001] The invention belongs to the technical field of decorative plates. In particular, it relates to a non-staining and finger-mark-free high-pressure decorative board and a preparation method thereof. Background technique [0002] Traditional high-pressure decorative panels use monochrome or printed decorative paper as the decorative layer, kraft paper as the reinforced and thickened substrate, and thermosetting resin as the impregnated and bonded material after high-temperature and high-pressure molding, and part of the surface of the decorative layer is covered with colorless and transparent Surface paper is used to enhance its surface resistance. In the above process, due to the unstable quality of pigments, dyes, fillers, and printing oils used in decorative paper, different levels of UV resistance, and low-grade printing pastes are not light-resistant at all. The surface resin of ordinary high-pressure decorative boards generally adopts melamine for...
