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 of a PETG surface layer preheating step: preheating a PETG material through an ultra mirror surface roller; controlling the temperature to be 120 to 140 DEG C to obtain a preheated PETG material; a PVC bottom layer preheating step: preheating aPVC material; controlling the temperature to be 140 to 150 DEG C to obtain a preheated PVC material; a compounding step: pasting the preheated PETG material and the preheated PVC material; then, performing hot pressing through a calendaring machine; controlling the temperature to be 160 to 180 DEG C; obtaining a composite material layer formed by a PETG surface layer and a PVC bottom layer; a cooling step: cooling the composite material layer, and obtaining the PETG and PVC composite decoration material. The composite decoration material has the characteristics of good mechanical performance,good flattening performance, no upwarp, high light, high brightness, transparency and attractive appearance; meanwhile, after the human body contacts the composite decoration material, poor sequela cannot be generated on the human body.

Description

technical field [0001] The invention relates to a decoration material, in particular to a PETG and PVC composite decoration 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 tumor related problems. PETG is a transparent, non-crystalline copolyester. The full name of PETG is polyethylene terephthalate-1,4-cyclohexanedimethanol. It is a polycondensation product of three monomers of terephthalic acid (PTA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by transesterification. Compared with PET, it has more 1,4 -Cyclohexanedimethanol comonomer has more ethylene glycol comonomer than PCT, so the performance of PETG is quite different from PET and PCT. PETG sheet has outstanding toughness and high impact strength, its impact strength is 3...
