Background technique
Riding carpeting is chiefly used in by the molding three layers of composite carpet of extrusion calendaring machine using polypropylene material at present
Decoration, especially baggage compartment carpet and luggage case left and right sides mask.This kind of carpet is divided into three layers, the upper and lower be polypropylene without
Woven fabric class felt, middle layer are polypropylene material class sandwich layer, and this kind of core material is mostly modified polypropylene material.This kind of core material
It is most of to be made of single extrusion grade low-flow polypropylene material, partially low-flow is fabricated to using PP and mineral powder
Modified polypropylene material makes.Many low-flow High-impact Polypropylenes for squeezing out carpet manufacture manufacturer and using, melt
Body flow rate is generally between 1-3g/10min.Due to the influence of cost, portioned product can partially use this kind of low-flow
Regenerating polypropylene is produced.Due to the influence of above two factor, the smell and VOC for causing sandwich layer matrix are difficult to solve, nothing
Method meets requirement of the people to the environment friendly of vehicle inside decoration part material.
Summary of the invention
In view of this, the present invention is directed to propose a kind of low volatility modified polypropylene composite material, preparation method and its answering
With, a kind of low smell suitable for extrusion calendaring production is provided, low volatility, it is environment amenable, it is applied to baggage compartment carpet
Sandwich layer product.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:

A kind of preparation method of low volatility modified polypropylene composite material, includes the following steps:
Raw material is uniformly mixed, by screw extruder melting extrusion, is granulated, extruder temperature setting includes 140-200
DEG C, screw speed 400-600rpm, feeding capacity 400-800kg/h.
A kind of application of low volatility modified polypropylene composite material, the material are applied to luggage case for automobile carpet sandwich layer.
Compared with the existing technology, a kind of low volatility modified polypropylene composite material of the present invention, preparation method and
Its application has the advantage that
Product of the present invention melt flow rate (MFR) 2-6g/10min, tensile strength 25-35MPa, bending modulus 900-
1400MPa, Izod notched impact strength 7-30kJ/m2, heat distortion temperature (0.45MPaMPa) >=90 DEG C, oder levels (according to
According to public PV3900)≤3.5 grades, thermo-oxidative ageing (150 DEG C, 700h) post-tensioning strength retention >=95%, the low smell of satisfaction,
Rigidity-toughness balanced, heat resistance, the subsequent hot-forming requirement of ageing-resistant and baggage compartment carpet composite board, can be good at applying
Into baggage compartment carpet sandwich layer product by bus.
The preparation method of low volatility modified polypropylene composite material of the present invention have it is easy to operate, material property is stable,
Excellent smell is suitble to the characteristics of extrusion calendaring molding.
Raw material action principle:
By the present invention in that can not be declined and be made guaranteeing other mechanical properties of material with low flowing homopolypropylene
In the case that cost is relatively low, the mobility of modified polypropylene composite material is effectively reduced, while having the characteristics that low smell, is had
The sandwich layer of low smell composite carpet is formed conducive to extrusion calendaring；
Mobility high impact resistance polypropylene resin in addition is effectively improved in the case where additive amount (40-60 parts by weight)
The rheological behaviour of PP composite material improves the mobility of modified composite material, while having the characteristics that low smell, favorably
In the illiquidity for improving low-flow homopolypropylene matrix, while the spy that the impact property that improves homopolypropylene is low
Point.So the addition of middle mobility high impact resistance polypropylene, forms and low flowing homopolymerization polypropylene physical mechanical property and stream
The complementation of dynamic property, the two are blended the matrix to be formed, fully meet the low temperature extrusion (list including re-entrant trough profiled steel sheeting of extrusion calendaring
The temperature of screw extruder temperature of each section and T-type mouth mold), the smell that low temperature extrusion is conducive to composite material is effectively protected
It holds.
Antioxidant is added, the degradation that polypropylene generates in process is effectively inhibited, is reduced since polypropylene material decomposes
The smell generated afterwards, and assign and squeeze out the excellent heatproof air aging performance of compound baggage compartment carpet.
Carbon black is added, when advantageously reducing tradition using black masterbatch, modified polypropene is made due to the addition of black masterbatch
It is promoted at smell, main reason is that the common polyolefin wax class in black masterbatch affects greatly composite material.Institute
It is dyed so that present invention uses inorganic particle, while reaching manufacturer and require color, whole change is effectively reduced
The smell of property polypropylene material.
Lubricant is added, promotes the good dispersion between each ingredient of blend, while playing melt polypropylene and processing
Inside and outside lubricity in the process, also functions to effect on thermal, is conducive to extrusion calendaring machine in 180-210 DEG C of progress low temperature extrusion
Calendering, effectively reduces the smell of finished product.
