Abstract

The invention discloses a PVC stone-plastic floor with round corners and round corner processing equipment of the PVC stone-plastic floor, and belongs to the technical field of floors. The PVC stone-plastic floor comprises a floor body; the floor body is composed of a backing material layer, a reinforced middle material layer, a color film layer, a wear-resistant layer and a UV protective layer; the backing material layer, the reinforced middle material layer, the color film layer, the wear-resistant layer and the UV protective layer are sequentially laminated from bottom to top; each of the backing material layer and the reinforced middle material layer comprises processing aids such as PVC resin, ground calcium carbonate, kaolin, a DOTP plasticizer, a calcium-zinc stabilizer, carbon fibers, petroleum resin and carbon black; the carbon fiber material and the calcined kaolin are introduced as auxiliary filling materials, the problem of thermal expansion and cold contraction of the floor is better controlled by utilizing the stability of the carbon fibers and the porcelainization effect of the kaolin after high-temperature calcination, the situation that the floor fillet effect rebounds along with temperature change is avoided, and the equipment can be applied to production of the stone-plastic floor with a wear-resistant layer with the thickness being 0.30 mm or below; and the thinner the wear-resistant layer is, the better the fillet effect is.

Description

technical field

[0001] The invention belongs to the technical field of flooring, and in particular relates to a PVC stone-plastic floor with rounded corners and processing equipment for rounded corners thereof. Background technique

[0002] At present, in order to solve the height difference and shrinkage joints in product paving and enhance the three-dimensional aesthetic feeling between the sheets, PVC stone-plastic sheet flooring adopts "V"-shaped chamfering treatment. ° chamfering tool cut into a bevel; this process requires a high thickness of the wear-resistant layer on the floor surface, which needs to reach a thickness of 0.50mm or more. At present, in the construction industry, the office system and home furnishing with the largest demand for PVC stone-plastic floor Most of the systems use a wear-resistant layer with a thickness of 0.30mm or 0.20mm, and this type of product often cannot be chamfered according to the traditional process, and its use is limited. If ro...

Examples

Embodiment 1

[0029] see figure 1 , the present invention provides a PVC floor with rounded corners, including a floor body 1, the floor body 1 is composed of a bottom material layer 101, a reinforced middle material layer 102, a color film layer 103, a wear-resistant layer 104 and a UV protection layer 105 , the bottom material layer 101, the reinforced middle material layer 102, the color filter layer 103, the wear-resistant layer 104 and the UV protection layer 105 are sequentially pressed together from bottom to top, and the bottom material layer 101 and the reinforced middle material layer 102 both include PVC Processing aids such as resin, heavy calcium carbonate, calcined kaolin, DOTP plasticizer, calcium zinc stabilizer, carbon fiber, petroleum resin and carbon black.

[0030] Its main production process is as follows:

[0031] Calendering: Through the automatic metering and mixing system, PVC resin, 325 mesh ground calcium carbonate, 800 mesh calcined kaolin, DOTP plasticizer, cal...
