Embodiment 1

[0022] Embodiment one: if figure 1 As shown, a flexible thermosetting resin impregnated paper high-pressure laminated board, which includes an impregnated film paper facing layer 1, a veneer balance layer 2, and the impregnated film paper facing layer 1 and veneer balance layer 2 are subjected to high temperature Thin high-pressure laminates are formed by heat-compression lamination.

[0023] Impregnated adhesive film paper finish layer 1 is the wood-based panel surface finish layer formed by impregnating special paper with initial polycondensate or prepolymer of synthetic resin, and then drying. The synthetic resin may be selected from urea-formaldehyde resin, phenol-formaldehyde resin, modified melamine resin, guanamine resin, or dipropylene phthalate resin. The synthetic resin in this embodiment has selected urea-formaldehyde resin for use.

[0024] The veneer balance layer 2 can be selected from natural veneer, natural veneer, reconstituted decorative veneer, veneer obta...

Embodiment 2

[0027] Such as figure 2 As shown, the difference between this embodiment and the first embodiment is that natural veneer is selected as the veneer balance layer 2 , and the bottom of the veneer balance layer 2 is also provided with kraft paper 3 .

Embodiment 3

[0029] Such as image 3 As shown, the difference between this embodiment and the first embodiment is that: the bottom of the veneer balance layer 2 is also provided with a non-woven fabric 4 .

Abstract

The invention discloses a bendable thermosetting resin impregnated paper high-pressure laminate which comprises a thermosetting resin impregnated paper surface layer (1) and a veneer equilibrium layer (2), and the thermosetting resin impregnated paper surface layer (1) and the veneer equilibrium layer (2) form the thin high-pressure laminate through interlayer compounding. The thermosetting resin impregnated paper surface layer (1) is an artificial board surface decoration material prepared by drying dedicated paper impregnated with initial polycondensate or prepolymer of synthetic resin. The high-pressure laminate has the advantages of good chamfer bending property, good waterproofing property, good flame resistance, good environmental protection property, convenience without surface treatment after coating, good decorative property, smoothness, cleanness, no need of painting, easy maintenance, simple production process, short thermocompression time, energy saving and high efficiency. The high-pressure laminate can be widely applied to coating lines of door pockets and door windows and can also be directly used as decorative surfaces of door plates and cupboards.

Description

technical field [0001] The invention relates to a decorative material, in particular to a bendable thermosetting resin impregnated paper high-pressure laminate. Background technique [0002] At present, in the production of cabinets and door covers, thermosetting resin-impregnated paper high-pressure laminates (fireproof boards) are often used. Fireproof boards are made of base paper (titanium powder paper, kraft paper) impregnated with melamine and phenolic resin at high temperature and high pressure. . The production of this product generally adopts the cold-hot-cold pressing process, the production process is complicated, the production cycle time takes about one hour, and the energy consumption is relatively large. Also, the product requires backside sanding. The thickness of its product is generally 0.7mm. Due to its thick thickness, it is usually not used for cladding, especially at the corners, which has poor bending performance. Contents of the invention [0003...
