Abstract

Relating to the technical field of high polymer materials, the invention provides a low odor and low VOC flame retardant modified HIPS material and a preparation method thereof. The low odor and low VOC flame retardant modified HIPS material is prepared from the following raw materials: HIPS resin, a flame retardant, a toughening agent, a processing aid, an antioxidant and an odor absorbent. The invention adopts the flame retardant, the toughening agent and the odor absorbent for modification treatment of the HIPS main material, so that the material can have excellent flame retardant performance and low odor level, and the styrene monomer content is greatly reduced, thus lowering the odor of polystyrene. The material provided by the invention can be used for household electrical applianceshells, office electric appliance shells and other fields, and the use range of the material is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-odor, low-VOC flame-retardant modified HIPS material and a preparation method thereof. Background technique [0002] As my country's air pollution and environmental quality decline become more and more serious, the public's awareness of environmental protection and health has increased, and people have put forward higher requirements for indoor odor and air quality. High-impact polystyrene (HIPS) has good comprehensive performance and is widely used in housing components such as household appliances, office equipment, and daily necessities. With the progress of society and the improvement of usage requirements and environmental protection awareness, the flame retardant performance of plastic products, the requirements for odor and VOC are becoming more and more stringent. [0003] Due to the constraints of synthesis methods and production process conditions, the ...
