Description
Technical Field
The invention belongs to the field of macromolecules, and particularly relates to a low-odor low-emission PC/ABS alloy material, and a preparation method and application thereof.
Background
The PC/ABS alloy material is one of general materials for automotive interior parts, such as instrument panel frameworks, auxiliary instrument panels, ceiling controllers, air-conditioning air outlets, demisting grilles, interior rearview mirrors and the like.
As the air quality safety in the automobile is more and more emphasized by people, the research and development of PC/ABS alloy materials with low VOC (volatile organic compounds) content and low odor are imperative.
Much research has been done on how to reduce the odor and VOC content of PC/ABS alloy materials. Such as: patent document CN101469122A discloses: a PC/ABS alloy material with low odor and low emission comprises the following components: prepared from 50-80% of PC resin, 10-45% of ABS/PP graft, 1-5% of hydrophobic odor adsorption master batch, 0.1-1% of antioxidant and 0-5% of other additives; the hydrophobic odor adsorption master batch is prepared by mixing, extruding and granulating attapulgite modified by ABS resin and quaternary ammonium salt surfactant. The method mainly utilizes the adsorption function of the hydrophobic adsorption master batch, so that the method can better adsorb the dispersed substances, but the alkaline surfactant can affect PC, and finally can seriously affect the mechanical property, particularly the impact property, of the system. Patent document CN103554867A discloses: a low VOC high performance PC/ABS alloy material: the ABS resin is prepared from 30-80% of PC resin, 5-50% of ABS resin, 1-10% of compatilizer, 0.1-1% of odor absorbent and 0.1-1% of processing aid. Although this method can effectively reduce the odor level of the product by adding an odor absorbent, the reduction effect on VOC is not good. Patent document CN103709704A discloses: a low odor, low emission PC/ABS alloy comprising the components: 30-80% of PC resin: ABS resin: 4 to 66.4 percent; a compatilizer: 2 to 10 percent; 1-5% of water master batch; 0.1 to 3 percent of auxiliary agent. In the patent document, jellyfish particles with high-melt foamed PP as a carrier are used as a stripping agent, so that various volatile small molecules and organic compounds generated in the processing process can be effectively removed without influencing the mechanical properties of the jellyfish particles, but the PP and PC/ABS systems have poor compatibility, and a large amount of compatilizers are required to be added to improve the compatibility, so that the cost is high and the mechanical properties are poor.
Therefore, a PC/ABS alloy material with low odor and emission and excellent mechanical properties is urgently needed.
