Abstract
The invention discloses a polypropylene composite used for automotive interior decorative parts. The technical scheme is that the polypropylene composite used for automotive interior decorative parts comprises the following material, by weight: 45-90 parts of a PP resin, 5-8 parts of high-density polyethylene (HDPE), 0-15 parts of a toughening agent, 0-20 parts of a filling agent, 0.2-1 part of an antioxidant, 1-5 parts of a compatilizer, 1-5 parts of a scratch-resistant agent, 1-5 parts of an odor absorbent, 0.5-1 part of a lubricant, and 0.2-0.4 part of a light stabilizer. The prepared polypropylene composite has characteristics of low VOC, scratch resistance, weather resistance, good mechanical property, and excellent integrated cost.
Description
Technical field
The present invention relates to technical field of polymer materials, particularly a kind of polypropylene composite material for automotive upholstery.
Background technology
Polypropylene (PP) is one of five large general-purpose plastics, and because its proportion is low, performance is good, is easy to machine-shaping and price is low etc. that feature is widely used in automobile interior exterior trim.But the shortcomings such as PP impelling strength is low and creep resistance is poor, molding shrinkage is large, dimensional stability is bad; Particularly polypropylene composite material is generally also containing certain smell, and smell source is mainly from the micromolecular compound that the thermal-oxidative degradation in the dissolvent residual added in catalyst residue, monomeric compound production process in polymerization process and the course of processing produces.It has had a strong impact on in-car air quality, seriously prosperously can injure the healthy of officer and passenger inside the vehicle.Above-mentioned shortcoming limits the use of polypropylene composite material, considerably limit the use of polypropylene on the goods that odor profiles requirement is higher, particularly to long-term use of placing out of doors on goods and automobile product, therefore must improve polyacrylic odor properties and just can widen polyacrylic range of application.
