Embodiment Construction

[0025] The present invention is described in detail below in conjunction with specific embodiment:

[0026] In the 1-6 embodiments of the present application, the following components are selected, polystyrene selects melt flow rate 10g / 10min, styrene residual monomer content 100ppm, impact modifier in embodiment 1-4 The selected weight percentages are 1, 2, 3, and the selected weight percentages in Examples 5-6 are 4, 5; the flame retardant is titanium dioxide multi-layer coated gray red phosphorus, and the auxiliary agent is selected from the weight percentages 0.6 simethicone, and the coupling agent is selected from silane coupling agents with weight percentages of 0.7, 0.75, 0.8, 0.85, 0.9, and 1.0, respectively.

[0027] Each component used in Examples 1-6 is set as shown in the table below, and each component is premixed according to the amount in the table, and is blended and granulated by a twin-screw extruder with an aspect ratio of 25-40. The extrusion temperature i...

Abstract

The invention relates to a flame-retardant polystyrene resin. The composite comprises the following components in percentage by weight: 75%-78% of polystyrene, 1%-5% of impact modifier, 0.6% of auxiliary agents, 15%-25% of fire retardant, 3%-5% of flame-retardant assistant agent and 0.7%-1% of coupling agent.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a flame-retardant polystyrene resin composition. Background technique [0002] Polystyrene resin compositions are widely used in the field of office equipment housings such as printers, copiers, computers or household appliances due to their excellent processability, mechanical properties and heat resistance, and these products have an effect on the flame retardancy of materials. Higher requirements, styrene-based resins are flammable materials, and usually need to add flame retardants and additives to achieve the required flame retardant level. In actual use, the flame retardant auxiliary agent belongs to the field of inorganic flame retardants, and the amount is limited , if the amount used is too much, it will affect the impact resistance of styrene. [0003] Existing flame retardants include halogen flame retardants, organophosphorus flame retardants and inorganic flame reta...
