Abstract

The invention relates to a polycarbonate resin composition for outdoor communication cabinets, which comprises the following components in parts by weight: 100 parts of polycarbonate, 0.5-5 parts of compatilizer, 1-10 parts of flexibilizer, 0.1-15 parts of fire retardant, 0.1-0.2 part of anti-dripping agent, 0.05-5 parts of ultraviolet absorber, 1-10 parts of size stabilizer and 0.1-2 parts of antioxidant and lubricant. In the formula of the polycarbonate resin composition for outdoor communication cabinets, the compatibility of various components is relatively good; simultaneously, by the synergistic action of the lubricant and the antioxidant, the reduction of polycarbonate (PC) performance during the high temperature processing formation procedure is reduced, and the processing flow property of PC resin and the dispersing property of the fire retardant in the composition can be improved. The prepared PC resin composition has the advantages of good outdoor weather resistance, high impact strength, flexural strength and tensile strength, good fire resistant degree, and high flow property. In addition, the invention further relates to a preparation method of the polycarbonate resin composition for the outdoor communication cabinets.

Description

【Technical field】 [0001] The invention relates to the field of polymer materials, in particular to a polycarbonate resin composition for an outdoor communication cabinet and a preparation method thereof. 【Background technique】 [0002] Traditional outdoor communication cabinets are mainly made of metal. Metal communication cabinets are heavy in weight, complex in processing technology and high in cost. With the continuous development of the material industry, after modifying polycarbonate (PC) as the main material, the combined resin is used to manufacture outdoor communication cabinets, which is not only light in weight, easy to process, but also low in cost. However, the traditional polycarbonate outdoor communication cabinet, after polycarbonate is modified, the performance is reduced, and the processing fluidity and molding performance are not good. 【Content of invention】 [0003] Based on this, it is necessary to provide a polycarbonate resin composition for outdoor ...
