Description

Three-layer composite paper for furniture veneering and cladding

Technical Field

The utility model belongs to the technical field of furniture articles for use, a furniture wainscot and cladding note paper are related to, concretely relates to furniture wainscot and cladding are with three-layer composite paper.

Background

Surface materials such as plate-type furniture, wardrobes, cabinets, composite wood doors and the like are often faced with decorative paper (triamine paper for short) impregnated with melamine formaldehyde resin, or are faced with PU paper by plastic uptake and PVC film coating. However, the above facing materials each have advantages and disadvantages:

1. triamine paper veneer

The triamine paper is a common finishing material for the panel furniture, and is pressed and stuck on the artificial board after being impregnated with melamine formaldehyde resin or mixed with partial urea formaldehyde resin. The process has low production cost and basically meets the requirement of manufacturing furniture. However, the disadvantages are: (1) the melamine formaldehyde resin contains free formaldehyde, and the manufactured furniture contains formaldehyde which is harmful to human health; (2) the difference between the texture of the wood grain printed by the melamine paper and the texture of the solid wood is obvious. Therefore, it is only suitable for low-grade and environment-friendly environment.

2. PVC film suction plastic or cladding

The PVC film is used for producing plate-type customized furniture such as a wardrobe and a cupboard through plastic uptake or coating, is also used for producing composite assembled wood doors, is a good decorative material from the production and use angles, and has lower price and better processability. PVC is not environment-friendly, and firstly, HCL and plasticizer volatile matters are released by aging of PVC, so that the PVC is harmful to the environment and human health; secondly, PVC is easy to age and fade; thirdly, the difference between the PVC printing texture and the solid wood texture is obvious, and the PVC printing texture is a plastic material at a glance in visual effect.

3. PU paper veneer or cladding

The PU paper is used for manufacturing furniture for fast consumption after the artificial board is pasted or coated with the PU finish after the reinforced paper is printed with lines, and the product requirement is not high. However, the strength of the PU paper is low and the PU paper is easily broken when wrapped; in addition, the surface of the substrate is easily exposed if there are flaws, such as small pits, rough surface, etc., on the substrate, which makes the substrate unattractive. In addition, the PU paper has no barrier property, and formaldehyde or other harmful substances in the artificial board are released to influence the health of people.

In view of the above technical defects in the prior art, the development of a novel furniture facing and covering paper is urgently needed.

Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

Fig. 1 shows a schematic structural diagram of the three-layer composite paper for covering and covering furniture. As shown in figure 1, the utility model discloses a furniture wainscot is three-layer composite structure with three-layer composite paper with the cladding, and its surface is PU paper 1, the fine and close base stock 2 of bottom surface after for intensive processing, be equipped with barrier layer 3 between PU paper 1 and the fine and close base stock 2 after intensive processing.

Wherein, the surface of the PU paper 1 is printed with a wood grain surface. Generally, the PU paper 1 is a paper having a printed wood grain surface treated with PU. The PU paper is used as the surface, no paint is needed, and the texture of the printed wood grain or stone grain is very vivid and is more vivid than the traditional decorative paper.

However, the strength of the PU paper is low, the PU paper is easy to break when being coated, and the surface of the base material is easy to expose if flaws exist on the surface, such as small pits and rough surface, of the base material, so that the PU paper is not attractive. Therefore, in the utility model discloses, compound the fine and close base stock 2 after the intensive treatment of one deck below PU paper 1. The strength is improved by the strengthened dense base paper 2, the stiffness of the paper is improved, and the surface of the base material is rough or has flaws to cover.

The utility model discloses in, it is right compact base paper 2 after the intensive treatment has certain requirement, just want closely knit, and density is high, and compound back like this, the stiffness is high, if the base paper is too soft, or density is low, makes anti mar just very poor, has just that the thing is drawn, has the indent of drawing. Therefore, in the present invention, the densified base paper 2 after the strengthening treatment is required to have a density of 0.95 to 1.3g/cm in the densified base paper 2 after the strengthening treatment³.
