Abstract
A polypropylene resin composition used to make plastic board such as internal decorative parts of car, instrument panel, etc. contains such components as polypropylene,thermoplastic elastomer, high-density polyethylene, copolypropylene, wollastonite, calcium carbonate, talc powder, barium sulfate and inorganic filler, and features excellent vacuum forming performance, and balanced digidity, toughness and refractory properties.
Description
The present invention relates to a kind of the shock-resistant of vacuum forming that be used for, the polypropylene resin composite that rigidity is good, the sheet material that this polypropylene resin composite is made can be used as fascia body supports framework material.
Usually, adopt the ABS resin composition to make the instrument board framework material, because this resin combination temperature tolerance is poor, cause range of application not extensive, JP0011313 has reported a kind of vacuum forming polypropylene resin composite, and said composition is to add high density polyethylene(HDPE) and mineral filler improves its rigidity in crystalline polypropylene resin, shock resistance and vacuum forming performance, but the resistance to impact shock of said composition co-mixing system is low, and rigidity, toughness and stable on heating harmony are relatively poor.
In order to overcome the low shortcoming of shock resistance in the prior art, the invention provides a kind of high rigidity that has, the shock-resistant and good polypropene composition of vacuum forming performance.
Another object of the present invention has provided the method for making and the application of above-mentioned resin combination.
The raw material of polypropylene plastic uptake plate of the present invention is a kind of polypropylene resin composite, comprises following component and composition: (weight percentage)
Polypropylene 30-60
Thermoplastic elastomer 5-10
High density polyethylene(HDPE) or
Linear low density polyethylene 5-20
Co-polypropylene 5-20
Compound inorganic stuffing 5-40
Above-mentioned polypropylene restrains/10 fens for homo-polypropylene MI=0.5-2, above-mentioned thermoplastic elastomer is terpolymer EP rubber or styrene-butadiene block copolymer (SBS), above-mentioned high density polyethylene(HDPE) MI=1.3-2.0 gram/10 minutes or linear low density polyethylene MI=0.5-2 gram/10 minutes, above-mentioned co-polypropylene MI=1-2 gram/10 minutes, above-mentioned compound inorganic stuffing is the bar-like silicon lime stone, lime carbonate, talcum powder and barium sulfate and composition thereof, above-mentioned each component is put into homogenizer carry out uniform mixing, make polypropylene resin composite at 200-250 ℃ with twin screw extruder.
Above-mentioned polypropylene resin composite is added in the forcing machine,, introduce three-roller calendar shaping, cooling, shearing again by T type head extruding sheet melt.Obtain the sheet material that thickness is 0.5-5mm.
Not only vacuum forming performance of polypropylene resin composite of the present invention is good, and have enough rigidity, toughness and a thermotolerance, be the harmony of mechanical property, performance index are as follows: tensile strength extension at break Izod 23 ℃ of modulus in flexure flexural strengths of notched Izod impact strength (MPa) are (J/m) (GPa) (MPa) 20-30 100-200 80-150 0.9-2.5 20-35 (%)
Be made into plastic uptake sheet material, cost is low, and complete processing is simple, can be at household electrical appliance, and use as the plastic uptake plate in the mechanicals field, is particularly useful as the fascia or the automotive upholstery of plastics sucking moulding.
