Problems solved by technology
However, due to the large specific surface area of carbon black, it is difficult for flame retardant materials to form carbon, and carbon black itself also has a burning state, so it is difficult to achieve a flame retardant grade of 1.0mm V-0
[0004] In view of this, it is necessary to develop a halogen-free flame-retardant PC antistatic material to solve the problem of poor flame-retardant effect of PC after adding carbon black in the prior art

Abstract
The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PC antistatic material and a product thereof. The halogen-free flame-retardant PC antistatic material comprises the following components: PC resin, acetylene carbon black and flame retardant. The product is produced by molding the halogen-free flame-retardant PC antistatic material. The halogen-free flame-retardant PC antistatic material of the invention can still have excellent flame retardancy after adding carbon black by adding the compound flame retardant.
Description
【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PC antistatic material and its products. 【Background technique】 [0002] With the multi-functionalization of plastic products and the high integration of electronic circuits, materials with conductive properties are being used more and more widely. PC materials (polycarbonate, Polycarbonate) have high impact resistance and their own flame retardancy can reach V -2. Good weather resistance, widely used in electronic and electrical products, but the contact between plastic and current-carrying devices, or friction with other material objects will cause static electricity in the plastic tape, which will cause static electricity accumulation and signal interference, which is not conducive to plastic The application of the product in the fields of printers, home appliance casings or signal line connectors. [0003] The surface resistance of ...
