Problems solved by technology

[0003] At present, decorative veneer (unpainted) with non-woven fabric or backing paper on the back is usually used in the veneer of curved surfaces and right-angled surfaces of wood products and furniture decoration, but the non-woven fabric used in this type of composite veneer is made of petroleum As a raw material, it is difficult to completely degrade, and non-woven veneer wood-based panels often need to be coated with various adhesives, which is relatively poor in water resistance and not environmentally friendly; in addition, uncoated non-woven veneer decorative veneer After finishing, the process of painting, drying and polishing is relatively complicated, and the production efficiency is low

Embodiment 1

[0026] a) Plane the wood into 0.06mm decorative veneer;

[0027] b) Coat the silane coupling agent on the plastic film with a thickness of 0.08mm, the coating amount of the silane coupling agent is 3% of the plastic film, and let it stand for 5 minutes;

[0028] c) heat-compressing the decorative veneer described in step a to the decorative film described in step b to form a composite decorative veneer;

[0029] d) Roll-coat ultraviolet (UV) curing primer on the surface of the composite decorative veneer, and make a flexible composite decorative veneer with a paint film that meets the requirements after one or more steps of painting, drying, and sanding.

[0030] e) Coupling agent is applied on the finished flexible composite decorative veneer with paint film, the coating amount is 3%, and after standing for 20 minutes, the billet is assembled, and it is hot-pressed in the hot-pressing plate of the hot-pressing machine. The pressing plate heats up and the hot pressing plate e...

Embodiment 2

[0033] Plane the wood into 0.2mm decorative veneer;

[0034] Add maleic anhydride-grafted polyethylene particles to the linear low-density polyethylene particles, and extrude them through an extruder to form a 0.08mm thick plastic film;

[0035] c) heat-compressing the decorative veneer described in step a to the plastic film made in step b to form a composite decorative veneer;

[0036] d) Roll-coat ultraviolet (UV) curing primer on the surface of the hot-pressed composite decorative veneer, and make a flexible composite decorative veneer with a paint film that meets the requirements after one or more steps of painting, drying, and sanding.

[0037] e) Place the finished flexible composite decorative veneer with paint film on the medium density board substrate, and after forming the billet, press it in the hot pressing plate of the hot press to form it. The hot pressing pressure is 1.6Mpa, and the hot pressing temperature is 160°C, hot pressing time is 1.5min;

[0038] f) Rel...

Abstract

The invention discloses a flexible compound decorative veneer facing process. The flexible compound decorative veneer facing process comprises the step of heating and pressing a flexible compound decorative veneer which is compounded and reinforced by plastic through a hot press, and adhering the flexible compound decorative veneer to curved surfaces or planes of a surface of a substrate, wherein the flexible compound decorative veneer comprises a decorative veneer layer and a plastic film layer; the plastic film layer is compounded on the decorative veneer layer by heating and processing; the veneer layer is composed of natural decorative veneers or recombined decorative veneers with thickness of 0.06-0.3mm; the plastic film layer is made of processed or unprocessed polyethylene, polypropylene or other materials; thickness of the plastic film layer is 0.02-0.5mm. According to the flexible compound decorative veneer facing process, complex processes of painting, drying, sanding and polishing, particularly sanding and polishing of the curved surfaces and the like in the conventional process are reduced; the production efficiency and the utilization rate of precious wood are greatly improved; the water resistance performance, flexibility performance and environmental-friendly performance of the decorative veneer facing are improved; the production cost of facing is reduced; the flexible compound decorative veneer facing process is good in application prospect.

Description

technical field [0001] The invention relates to a veneer process of composite decorative veneer, which belongs to the wood processing industry and is a new process adopted in the fields of decoration, wood products, furniture moldings, and door and window plate decoration. Background technique [0002] With the scarcity of precious wood resources and the continuous research on wood product processing technology, decorative veneer is widely used in the manufacture of wooden furniture, wooden floors and wooden doors. [0003] At present, decorative veneer (unpainted) with non-woven fabric or backing paper on the back is usually used in the veneer of curved surfaces and right-angled surfaces of wood products and furniture decoration, but the non-woven fabric used in this type of composite veneer is made of petroleum As a raw material, it is difficult to completely degrade, and non-woven veneer wood-based panels often need to be coated with various adhesives, which is relatively...
