Problems solved by technology

[0004] In view of this, the present invention aims to solve the problem that traditional extruders prepare high-gloss materials through screw pushing and shearing extrusion processing, which will cause serious damage to the dimensional integrity of pearlescent resin and affect the gloss of composite materials, as well as feeding In the process, because the pearlescent resin cannot be uniformly dispersed, it is difficult to stably discharge the material. To provide a high-gloss, low-odor, flame-retardant PC material and its preparation method and device

Abstract

The invention belongs to the technical field of material processing, and relates to a high-gloss, low-odor and flame-retardant PC (polycarbonate) material as well as a preparation method and device thereof. The raw materials comprise, in parts by weight, 95.3 to 99 parts of PC resin, 0.1 to 2.0 parts of pearlescent resin, 0.05 to 0.1 parts of silicone oil, 0.5 to 1.0 part of an adsorbent, 0.2 to 0.6 parts of a heat stabilizer, and 0.1 to 1.0 part of a flame retardant. In the preparation process, pearlescent resin is added from a pearlescent resin feeding device close to the head end of an extruder. The size integrity of the pearlescent resin in the preparation process is greatly retained, a considerable part of pearlescent resin is selectively dispersed on the surface layer of the plastic,the content of the pearlescent resin on the surface layer is increased, so that the glossiness of the PC material is greatly improved, the flame retardance is also improved, the total use amount of the pearlescent resin is reduced, the cost of the composite material is reduced, and the impact toughness and the ductility are also greatly improved compared with an equivalent high-gloss material prepared by a traditional method.

Description

technical field [0001] The invention belongs to the technical field of material processing, and relates to a high-gloss, low-odor, flame-retardant PC material and a preparation method and device thereof. Background technique [0002] With the development of society, people's requirements for beauty are getting higher and higher, and high-gloss PC materials are used more and more widely. Traditional high-gloss PC materials are realized by spraying primer first, and then spraying high-gloss topcoat or electroplating. Since the primer is a thermosetting material, it is difficult to melt again. The physical properties and recycling performance of the plastic products after spraying are poor, which will affect the re-use use; and the spraying process is cumbersome, and the reject rate is high; the primer contains a large amount of toxic and harmful organic solvents, which is easy to produce toxic and harmful gases and dust, seriously endangering human health, and also causing pro...
