Problems solved by technology

[0002] The PC / ASA alloy flame retardant materials currently used in the market basically use halogen-based flame retardants. Although they meet the requirements for fire protection, the mechanical properties of the material itself will decline significantly, and the halogens do not meet the requirements of green flame retardants. Health and Environmental Protection Requirements

Abstract

The invention discloses a high-performance halogen-free flame-retardant PC / ASA alloy and a preparation method thereof. The high-performance halogen-free flame-retardant PC / ASA alloy is prepared from the following raw materials in parts by mass: 45-75 parts of PC, 10-25 parts of ASA, 5-20 parts of a halogen-free flame retardant, 0.05-0.5 part of an anti-drip agent, 5-10 parts of a flexibilizer, 0.1-1.5 parts of an anti-oxidant, 5-10 parts of a compatilizer and 0.01-0.5 part of a lubricant. The preparation method of the high-performance halogen-free flame-retardant PC / ASA alloy comprises the following steps: (1) weighing the following raw materials: 45-75 parts of PC, 10-25 parts of ASA, 5-20 parts of the halogen-free flame retardant, 0.05-0.5 part of the anti-drip agent, 5-10 parts of the flexibilizer, 0.1-1.5 parts of the anti-oxidant, 5-10 parts of the compatilizer and 0.01-0.5 part of the lubricant; (2) blending, performing melt extrusion and pelleting. The high-performance halogen-free flame-retardant PC / ASA alloy is relatively good in flame retardant property and mechanical property, and environmentally friendly.

Description

technical field [0001] The invention relates to a high-performance halogen-free flame-retardant PC / ASA alloy and a preparation method thereof. Background technique [0002] The PC / ASA alloy flame retardant materials currently used in the market basically use halogen-based flame retardants. Although they meet the requirements for fire protection, the mechanical properties of the material itself will decline significantly, and the halogens do not meet the requirements of green flame retardants. Health and environmental protection requirements. Therefore, it is urgent to develop a PC / ASA alloy flame-retardant material that meets environmental protection requirements and can obtain better mechanical properties. Contents of the invention [0003] The object of the present invention is to provide a high-performance halogen-free flame-retardant PC / ASA alloy and a preparation method thereof. [0004] The technical scheme that the present invention takes is: [0005] A high-perf...
