Description
HALOGEN-FREE MODIFIED HIGH-FILLING RECYCLABLE PLASTIC BOARD
AND METHOD OF FORMING THE SAME
TECHNICLAL FIELD
The present disclosure relates to the field of plastic flooring technology, and more particularly to a halogen-free modified high-filling recyclable plastic board and a method of forming the same.
BACKGROUND ART
At present, commercially available plastic floors are generally with pvc as a main plastic raw material. Although its products are environmentally friendly when used, they may be decomposed and toxic gases such as hydrogen chloride and dioxins may be released in processing and heating. With deepening of people's concept of environmental protection, increasingly more calls for halogen-free products emerges in the market. Conventional halogen-free plastic materials suffer from their own drawbacks. For example, for Poly Ethylene (PE), although a large amount of stone powder can be filled, but with a large expansion ratio; boards molded with Polypropylene (PP) materials are with a small tension on its surface, with relatively difficult subsequent surface processing; and a melting point of a polyethylene terephthalate (PET) material is high and it is brittle, which cannot be filled with a large amount of stone powder.
SUMMARY
In view of problems described above, a halogen-free modified high-filling recyclable plastic board is provided in this disclosure, which is formed using a hot press process, without glue bonding and with good integrity; and the manufactured board is large in surface tension, its surface is easy to be processed and a substrate layer thereof has good compatibility with a printed layer and a protective layer, which can be recycled as a whole.

2 Technical schemes adopted in this disclosure are as follows. A halogen-free modified high-filling recyclable plastic board is provided in this disclosure, which includes a substrate layer and a printed layer and a protective layer disposed sequentially on the substrate layer from bottom to top.
Raw materials of the substrate layer include, by weight in percent, 20 to 25%
of PEAT resin, 70 to 75% of stone powder, 0.5 to 0.8% of chain extender, 1 to 2%
of white mineral oil, 3 to 6% PE, and 0.4 to 0.8% stearic acid.
Specifically, the PEAT resin can be polyethylene terephthalate¨co-polyethylene adipate, which is condensed and prepared by esterification reaction of PTA (Pure Terephthalic Acid), adipic acid, ethylene glycol, phosphoric acid and its ester derivatives, diethylene glycol, and a catalyst.
Performance parameters of the PEAT resin are as follows:
Intrinsic Viscosity: 0.85 to 0.9 dUg;
Terminal Carboxyl Group: 6 to 13 mmoVkg;
Diethylene Glycol: 1 to 1.5%;
Melting Point: 195 to 205 C.
The PEAT resin may function in adhering. The stone powder acts as a filler, increasing stability of products. The chain extender may serve to increase a length of the chain, and is not easy to be decomposed in processing. The white mineral oil may serve to lubricate and increase plasticization, thus facilitating extrusion.
In addition, the stearic acid also provides a lubricating effect. The chain extender is used together with the white mineral oil and the stearic acid, which makes the products easier to be shaped and not easy to be broken during extrusion.
The printed layer is a PETG (Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate)) white film, a printed film or a digital printed film. The protective layer may be a PETG transparent sheet or halogen-free resin (uv, pur). A surface of the protective layer is provided with textures, which can be pressed by steel plates and rollers or digitally printed. However, it is not limited to this, and the surface of the protective layer may also be with a planar structure.

3 The substrate may be with a single-layer or a multi-layer structure, and a bottom of the substrate may be provided with a balance layer and/or a silence pad.
The balance layer is can be a PETG transparent sheet.
Alternatively, the PEAT resin is prepared by esterification reaction of 65 to 70%
of PTA, 13 to 20% of adipic acid, 13 to 20% of ethylene glycol, 0.0012 to 0.0025% of phosphoric acid and its ester derivatives, 1 to 1.5% of diethylene glycol and 0.02 to 0.03% of catalyst, by weight in percent.
Alternatively, the PEAT resin is prepared by esterification reaction of 55 to 60%
of PTA, 13 to 20% of adipic acid, 13 to 20% of ethylene glycol, 0.0012 to 0.0025% of phosphoric acid and its ester derivatives, 110 1.5% of diethylene glycol, 0.02 to 0.03%
of catalyst and 10 to 15% of recycled PET, by weight in percent.
PET is polyethylene terephthalate. The recycled PET is from recycled beverage bottle flake. With the recycled PET, it is more environmentally friendly and does not affect overall performance of the prepared plastic board.
Alternatively, the catalyst is an antimony based catalyst, specifically ethylene glycol antimony. Since a structure of the ethylene glycol antimony has similar groups to that of ethylene glycol, according to similar miscibility principle, the ethylene glycol antimony has large solubility in ethylene glycol, good dispersibility, and has high antimony content and good activity, which facilitates esterification reaction.
Optionally, the chain extender is a copolymer containing epoxy functional groups. The active epoxy groups contained in the chain extender can react with carboxyl groups at a chain end of the PEAT resin, and a ring-opening temperature of the epoxy group is low, thus with high chain extension efficiency.
Specifically, it can be 2-methyl-2-propenoic acid oxiranylmethyl ester, which, together with the PEAT
resin condensed and prepared by the esterification reaction, has ester groups, which does not bring in new impurities.
Optionally, the PE is HDPE (high density polyethylene). HDPE has a high melting point, suitable for high temperature processing, with superior hardness, tensile strength, and creep resistance over low density polyethylene.
Performance parameters of HDPE are as follows:

Softening Point: 125 to 135 C.
A method of forming a halogen-free modified high-filling recyclable plastic board is further provided in the disclosure, specifically including following steps (1) to (4).
(1) PEAT resin, stone powder, chain extender, white mineral oil, PE, and stearic acid were stirred at a high speed until a stirring temperature reaches and then stirring is stopped.
(2) Extrusion molding is made by an extruder with multi-stage extrusion temperatures, pressing into sheets is performed by a steel roller so as to form a substrate layer;
(3) A printed layer is formed on a surface of the substrate layer by digital printing, rolling or adhering a patterned film layer.
(4) The protective layer is adhered or coated on the printed layer and then the protective layer is embossed to form a plastic board.
The multi-stage extrusion temperatures include five stages of extrusion temperatures sequentially set from high to low, the multi-stage extrusion temperatures range from 185 to 210 C, and duration for each of the stages of extrusion temperatures is from 13 to 17 s. Because of greater amount of stone powder in early stages, it is necessary to be with better plasticization in the first three stages, so warming is required. Further, vacuum treatment is performed between the third and fourth stages of temperatures with a vacuum of 0.8 mpa, so as to pump away gases generated or carried in processing, so that there is no bubble inside the board. In order to ensure full plasticization in the first three stages, it is necessary to process at a higher temperature, so as to avoid unplasticized or powdery materials being vacuumed away. The temperature after the plasticization needs to be reduced as materials are softer at a high temperature, such that the materials cannot be extruded and molded well, and thus the temperature is reduced.
