Problems solved by technology

Most of the existing PETG films are produced by extrusion casting machines, which have the disadvantages of poor flattening, shrinkage and warping, and poor aesthetics.
In the prior art, due to insufficient technical operating conditions for the compounding of PETG material and PVC, it is difficult to bond two sheets of different materials, and the finished product cannot remain transparent and beautiful after bonding

Abstract

The invention discloses a PETG and PVC composite decoration material and a preparation method thereof. The preparation method comprises the following steps: a PETG surface layer preheating step: preheating the PETG material through a super-mirror roller, and controlling the temperature at 120-140°C , obtain the preheated PETG material; PVC bottom preheating step: preheat the PVC material, control the temperature to be 140-150 ℃, obtain the preheated PVC material; composite step: preheated PETG material and preheated PVC material Paste together, and then heat-press through a calender, control the temperature at 160-180°C, and obtain a composite material layer composed of a PETG surface layer and a PVC bottom layer; cooling step: After cooling the composite material layer, PETG and PVC are obtained Composite decoration materials. The composite decorative material of the present invention has the characteristics of good mechanical properties, good flattening, no warping, high gloss, transparency and beauty, and at the same time, no adverse sequelae will be produced on the human body after touching it.

Description

technical field [0001] The invention relates to a decorative material, in particular to a PETG and PVC composite decorative material and a preparation method thereof. Background technique [0002] At present, most of the decorative skins used in cabinets, tables, chairs, doors, etc. are made of polyvinyl chloride (PVC) materials, and using them on the contact surface will cause human carcinogenicity and related problems such as tumors. PETG is a transparent, non-crystalline copolyester, the full name of PETG is polyethylene terephthalate-1,4-cyclohexane dimethanol ester. It is the product of polycondensation by transesterification of three monomers, terephthalic acid (PTA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM), which is 1,4 more than PET. -Cyclohexanedimethanol comonomer has more ethylene glycol comonomer than PCT. Therefore, the performance of PETG is quite different from that of PET and PCT. PETG sheet has outstanding toughness and high impact streng...
