Problems solved by technology

[0005] In the authorized notification number CN107325519B, a low-VOC PC / ABS alloy material and its preparation method are disclosed. Activated carbon and metal-organic framework compounds are added as adsorbents in the PC / ABS alloy material, and the residue produced during the extrusion process of the alloy material is The small molecular substances in the alloy are stored and fixed in the material stably. At the same time, cerium-doped titanium dioxide nanotubes are added as a degradation agent to degrade the adsorbed small molecular substances. However, the added cerium is easy to oxidize and destroy the stability of the PC / ABS alloy material. sex

Abstract

The invention discloses preparation of a low-VOC and low-odor PC / ABS alloy material, which is prepared from the following components in parts by weight: 30 to 85 parts of PC, 10 to 65 parts of ABS, 1 to 10 parts of copolymer, 0.1 to 0.5 part of chelating agent, 0.1 to 0.5 part of anti-UV (ultraviolet) agent, 0.1 to 0.5 part of antioxidant 1, 0.1 to 0.5 part of antioxidant 2, 1 to 3 parts of lubricant, 1 to 3 parts of amphoteric metal oxide and 1 to 2 parts of color master batch. The low-VOC and low-odor PC / ABS alloy material is prepared by the following steps: sequentially adding all the components into stirring equipment, conducting stirring and mixing, air-drying the mixture, and carrying out melt extrusion through an extruder, thereby obtaining the low-VOC and low-odor PC / ABS alloy material. The amphoteric metal oxide is added, so that the volatilization amount of volatile small molecules in the use process of the product is reduced, and adsorbed volatile small molecules can be effectively degraded, so that the product has the characteristics of low VOC and low odor.

Description

technical field [0001] The invention relates to the field of PC / ABS alloys, in particular to a low-VOC, low-odor PC / ABS alloy material and a preparation process thereof. [0002] technical background [0003] PC / ABS plastic alloy is a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer, which combines the excellent characteristics of PC and ABS, such as the formability of ABS material and the mechanical properties and impact strength of PC. And temperature resistance, anti-ultraviolet (UV) and other properties, have been widely used in automotive interior parts, medical equipment, home appliances and lighting equipment. [0004] However, there are many small molecular impurities in the PC / ABS plastic alloy, and volatile organic compounds (VOC): benzene, toluene, ethylbenzene, formaldehyde, acetaldehyde, acrolein, styrene, etc., have different degrees of damage to the human body. Especially for various automotive interior parts made of PC / ABS plastic alloys...
