Abstract
The invention relates to a transparent flame-retardant MPPO resin composition. The resin composition comprises PPO resin, PS resin, SPS resin, an SBC toughening agent, a flame retardant and an anti-dripping agent. According to the invention, five components with excellent compatibility, namely PPO, PS, SPS, SBC and a phosphate flame retardant, are selected and blended to obtain a transparent matrix; sBC is adopted as a toughening agent, preferably, the content of polybutadiene is 15-30%, and due to the fact that the content of polybutadiene is low, when the polybutadiene is dispersed in a matrix, the phase domain of the polybutadiene is small enough, and therefore the transparency of the material is not affected. Meanwhile, the SPS resin is also added and is opaque crystalline resin, and when the SPS resin is blended with the PPO / PS resin, the compatibility is good enough, so that even if the crystallization behavior of the SPS is changed, the crystallinity is obviously reduced, and the transparency of the material is not influenced.
Description
technical field [0001] The invention belongs to the field of materials, and in particular relates to a transparent flame-retardant MPPO resin composition and a preparation method thereof. Background technique [0002] With the development of flame retardant materials, many products with different characteristics have been launched. Among them, transparent flame-retardant products are a special type of product, because most flame-retardant materials are opaque. Transparent flame retardant materials are generally in great demand in industries such as sweeping robots, electronic appliances, and electric control boxes. At present, transparent flame retardant products with relatively excellent comprehensive performance are developed on the basis of PC resin, and Sabic's LEXAN is a relatively mature technology. TM Series of products, the official propaganda can be halogen-free flame retardant, 1.5mm thickness V0 grade (LEXAN TM 9915A). However, due to four reasons, transparen...
