Plastic product with double-color and double-material interlayer, and preparation method thereof

Abstract

The invention belongs to a plastic product with a double-color and double-material interlayer, and a preparation method thereof. The plastic product with the double-color and double-material interlayer is composed of an inner layer and an outer layer coated at the outer side of the inner layer, wherein the material for preparing the inner layer is white polyethersulfone resin particles; the polyethersulfone resin particles are prepared from 4,4'-double sulfonyl chloride diphenyl ether condensed with diphenyl ether under catalysis of anhydrous ferric chloride; the refractive index is 1.85; the glass transition temperature is 225 DEG C; the heat distortion temperature in the state of 1.82MPa is 203 DEG C; the material for preparing the outer layer is transparent plastic or prepared from polyethersulfone resin particles accorded with a composite organic pigment. By adopting the preparation method, the plastic product with the double-color and double-material interlayer is prepared from different raw materials of the inner layer and the outer layer, and has the advantages of being low in cost, strong in heat retaining property, vivid in color, and good in entertainment and functionality. The method has the advantages of being simple and practical, and low in manufacturing cost; an operation is facilitated.

Description

technical field [0001] The invention belongs to a two-color double-material interlayer plastic product and a preparation method thereof. Background technique [0002] Plastic products, especially plastic products for food and drink, should be processed with non-toxic white polyethersulfone resin particles. Although plastic products for food and drink made of polyether sulfone resin particles are non-toxic, they will not harm the human body. Cause harm, but its own poor coloring, monotonous, high cost, not beautiful; and the traditional plastic products used as dress food also have poor thermal insulation, entertainment and functional deficiencies. Contents of the invention [0003] The purpose of the present invention is to provide a double-color double-material sandwich plastic product and its preparation method, so that the double-color double-material sandwich plastic product is made of different raw materials for the inner and outer layers, and has the advantages of lo...
