Problems solved by technology

Although the flame retardancy of PC (oxygen index is 21% to 24%, and the flame retardancy reaches UL94V-2 level) is better than ordinary thermoplastic polymers (such as polyethylene, polypropylene, etc.), it is still difficult to meet certain application fields. There are requirements for permanent anti-fog and anti-scratch, so the PC material must be improved

Abstract

The invention discloses a formula and preparation process of a PC material with permanent fog resistance, scratch resistant and high transparency. PC resin, stearic acid monoglyceride, high-molecular polyester, butadiene, high polyglycidyl ester, alkyl silicone oil, a cross-linking agent and an antioxidant are proportioned according to certain parts by weight, the PC material is prepared by a stirrer, a reaction kettle, a double-screw or three-screw granulator, a granulator and a packaging machine, and the prepared product is tested, so that the product obtained by the invention has the best effects of permanent anti-fogging performance, scratch resistance, notch impact force, low temperature resistance, refractive index, glossiness and the like. The PC material can effectively achieve permanent anti-fogging and scratch-resistant effects, is widely applied to the fields of automobiles, optical lenses, protective masks, electronic appliances, high-end toys and the like, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of PC materials, in particular to a formula of a permanent anti-fog and scratch-resistant highly transparent PC material and a preparation process thereof. Background technique [0002] Polyethylene (PE) is a thermoplastic resin, odorless, non-toxic, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. Because polyethylene has the above characteristics and is easy to process and shape, polyethylene is suitable for product labels with high performance such as water resistance, oil and chemicals. Due to the excellent flexibility of PE, it is especially suitable for plastic bags, and it can also be used in situations where PVC label materials cannot be used due to environmental protection requirements. Polyethylene itself is a colorless and transparent material, which is widely used in many fields that require transparent materials. Although polyethylene ...
