Description

Ornamental melamine laminated floor covering material and manufacture method thereof

The present invention relates to ornamental floor covering and manufacture method thereof, specifically, relate to and decorate melamine laminated PVC floor covering, it is to form with the melamine sheet material lamination on the PVC plate with excellent physical property; The present invention also relates to make the method for this material.

The floor covering that is used for the commodity building now generally is smooth stone material or PVC brick and other material, as shown in Figure 1.In large quantities of building such as market and office building, stone floor material such as marble and granite are the materials of the most common use.Though this class stone material product durability is good, because of costing an arm and a leg, has now developed some substitutes.

The PVC brick product of having developed has two-tone marbling, and is similar with lithotome.These PVC bricks be crushed to that various erose material is suppressed or continuously compacting form, produce the PVC plate that one deck has two or more tones thus, obtain marbling effect shown in Figure 2.But, because therefore excessive use filler in the manufacture process is restricted in the natural sex degree of color and configuration aspects.

In order to improve the shortcoming of this respect, now developed ornamental polyvinyl chloride resin floor covering, as shown in Figure 3, it has laid printed layer on the PVC plate.

The represented this decorative floor cladding material that is bonded into by the compacting of one pile of material of Fig. 3 comprise lay successively following which floor: produce the base layer 1 that product thickness and levelling reconciliation of inventory are used; The printed layer 2 of representing decorative effect on the base layer 1 with art pattern; The hyaline layer 3 that protection printed layer 2 patterns are used; Make product have the face coat 4 of resistance tocrocking and scratch resistance; And under basic unit 1, be used for the balance layer 5 of adjustment.If base layer 1 itself can be regulated the balance of this floor covering, then balance layer 5 can save.

The manufacture method of above-mentioned traditional decorative floor cladding material comprises following step:

It is thick that the resin mixture of soft pvc or hard PVC is calendered to 2-3mm, makes base layer 1;

Manufacturing is layered on printed layer 2 and the hyaline layer 3 on the base layer 1, and is layered on the balance layer 5 under the base layer 1;

On the polyvinyl chloride resin sheet material, carry out drying after printing natural tone decorative pattern or the wooden tone pattern with photolithography or transfer method and make printed layer 2, the thickness of this polyvinyl chloride resin sheet material is 0.08-0.15mm, form with soft or the calendering of hard PVC compound, contain 10-20 weight % titanium oxide in the compound and make it to have good covering power;

Make hyaline layer 3 with the transparent PVC resin film that 0.1-0.95mm is thick, it is by rolling soft or the hard PVC resin mixture forms;

Soft or the calendering of hard PVC resin mixture are made the balance layer 5 of 0.32-0.95mm;

Printed layer 2, hyaline layer 3 and balance layer 5 are laminated on the base layer 1, this laminating method be with a press complete on the base layer above-mentioned printed layer that makes 2 and hyaline layer 3 and base layer 1 transfer put balance layer 5 after, carry out hot pressing; And

Be cured formation face coat 4 with ultraviolet ray after on hyaline layer 3, being coated with the face finish that 5-60 μ m principal component is urethanes or acrylate, form face coat 4 with heat cure or ultraviolet curing after perhaps being coated with a kind of main component and being urethanes or acrylate on hyaline layer 3, making thickness thus is the decorative floor cladding material of 2.5-5.0mm.

Though traditional decorative floor cladding material of making by above-mentioned this method is with low cost and easy for installation being widely used owing to it, because the face coat on its top layer not antipollution or anti scuffing thereby damage easily not.As a result, the frequent place of those dealings is with regard to contaminated or scratch, thereby it reduces in architectural purposes.

Afterwards, use a kind of decorative floor cladding material melamine resin, that superficial layer has high rigidity that do not have, solved above-mentioned these problems.Figure 4 and 5 are represented some traditional floor coverings like this.
