Description
Technical Field
The invention relates to the field of automotive interior materials, in particular to a low-glossiness high-impact flame-retardant PC/ABS alloy material and a preparation method thereof.
Background
In order to avoid potential safety hazards caused by strong stimulation of light reflection to drivers, automotive upholstery is generally subjected to extinction treatment, so that the glossiness of the interior trim is reduced as much as possible. Generally, there are three general approaches to reducing the gloss of interior trim parts: and (3) spraying and changing the surface texture of the interior trim part, namely, adopting dermatoglyph treatment or directly selecting low-gloss resin for injection molding. The PC (polycarbonate)/ABS (acrylonitrile-butadiene-styrene copolymer) blended alloy is an alloy plastic with excellent performance, has the advantages of PC/ABS, can reduce the melt viscosity of PC, improve the heat resistance and tensile strength of ABS, reduce the sensitivity of the internal stress and impact strength of a product to the thickness of the product, has excellent heat resistance and mechanical performance, has good surface gloss and attractive appearance, and is widely applied to the fields of automobiles, electronics, electrical appliances, office machines, household electrical appliances, communication and the like at present.
The PC/ABS alloy material is used as an important automotive interior part raw material, and in order to further improve the application of the PC/ABS alloy in automotive interior parts, the development of the PC/ABS alloy material with low gloss, impact resistance, high flame retardance and high cost performance is very necessary. The current methods for adjusting the glossiness of PC/ABS materials are roughly 4 types as follows: 1) the PC/ABS materials cannot be completely compatible, a compatilizer needs to be added in the production, and different compatilizers have different influences on the glossiness; 2) lubricants are present in small amounts in PC/ABS alloys but still affect their gloss; 3) the special polishing agent is added, and the special polishing agent can greatly reduce the glossiness of the PC/ABS material; 4) the injection molding process is changed, and the product obtained at higher mold temperature has higher glossiness.
At present, incompatible substances or reactive resins are added into the low-gloss PC/ABS, so that although the gloss is reduced, the toughness is seriously influenced, and the cost of the flatting agent is higher. Meanwhile, the fireproof performance of automotive materials is higher and higher, and particularly, the interior trim parts which do not have too much requirement on flame retardance in the past are provided. Therefore, the market urgently needs a flame-retardant PC/ABS alloy material which has low gloss without losing toughness and lower production cost.
