Description
Technical field
Present invention design field of high polymer material modification, and in particular to a kind of low smell, the plant of imitative flocking effect
Straw powder filling modified polypropylene material and preparation method.
Background technology
Polypropylene become due to light inexpensive, easy processing shaping and its good comprehensive performance most important general-purpose plastics it
One and fastest-rising plastic raw materials of dosage in automotive field nearly ten years.Modified polypropylene material is widely used in vapour
Interior gadget, mainly including instrument board, door-plate, column and glove compartment etc., usual woven fabric is coated, promoted in automobile
The quality class of gadget.But the complex procedures, production capacity reduce, cost increases, and textile fabric and used bonding
Agent can all enhance automotive upholstery smell.Therefore, how to reduce modified polypropylene material plastic sense and smell gradually into
For major main engine plants focus of interest.The quality experienced and used in automobile in order to further enhance consumer, develops
Staple fibre modified polypropylene material with imitative flocking effect.
Straw is the byproduct of agricultural production, first, chopping and returning, as fertilizer, utility value is than relatively low；Second is that make
For fuel, it is more as offal treatment, such as burning disposal, not only causes the wasting of resources, but also atmospheric environment can be polluted.Plant
It is subject to different degrees of thermal degradation in the process that straw powder is 100 DEG C or more in temperature, color is caused to be become by light yellow
Coffee color is added to light modified polypropylene material, has imitative flocking effect, and the hollow structure of straw powder uniqueness produces smell
Raw physisorption, while reducing material smell, can also generate light wheat fragrance type.Therefore, plant straw powder replaces
For staple fibre, the modified polypropylene material of light color is added to, with reference to grain design, is prepared with low smell and imitative flocking
The automotive upholstery of effect can substitute the finished product of textile fabric cladding.
The content of the invention
It is a primary object of the present invention to provide the straw powder filled modified poly- third of a kind of low smell, imitative flocking effect
Alkene material, the material, with reference to grain design, have imitated the effect of weaving flannelette by adding plant straw powder, have reached modeling sense
Purpose.
It is another object of the present invention to provide the preparations of above-mentioned low smell, the modified polypropylene material of imitative flocking effect
Method.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of plant straw powder filling modified polypropylene material of low smell, imitative flocking effect, by weight percentage, bag
Include following components：
40-99 parts of acrylic resin；
0-40 parts of ore body powder；
0-20 parts of toughener；
0.5-10 parts of plant straw powder；
0.1-1 parts of antioxidant；
Steady agent 0.1-0.5 parts of light.
Imitative flocking effect of the present invention is that the effect that plastic part is coated by one layer of textile fabric is imitated from visual effect
Fruit.
The acrylic resin is about one or more of homopolypropylene or copolymer polypropylene, and melt index is
20-50g/10min。
The mineral powder is the mixture of one or both of talcum powder or calcium carbonate, the grain size more than 95%
It is distributed in 0.5-5 μm.
The toughener is elastomer, common selected from ethylene-hexene co-polymers, ethylene-butene copolymer, ethylene-octene
Polymers, ethylene-propylene-octene terpolymer, the one or more of hydrogenation of ethylene-butadiene-styrene copolymer.
The plant straw powder is wheat stalk powder, rice straw powder, corn stalk powder, potato straw powder, rape straw
One or more mixtures in stalk powder and cotton stalk powder, the particle diameter distribution more than 95% is in 0.15-0.4mm.
The antioxidant is made of the primary antioxidant and auxiliary anti-oxidant arbitrarily than mixing, and primary antioxidant is tetrapentaerythritol
Ester；Auxiliary anti-oxidant is selected from least one of two hard ester of three (2,4- di-tert-butyl-phenyls) phosphite esters and thio-2 acid.
The steady agent of the light is selected from salicylic acid to octyl phenyl ester, two uncles of 3,5- di-tert-butyl-4-hydroxybenzoic acids -2,4-
At least one of butyl phenyl ester.
Since present invention is mainly used for automotive upholsteries, it is contemplated that appearance is often fabricated to light colour, so of the invention
Micro organic pigment or inorganic pigment are further included in material.Organic pigment is selected from permanent bordeaux, permanent yellow, phthalein feelings indigo plant, dark green etc.,
Inorganic pigment is selected from titanium dioxide, carbon black, iron oxide red iron oxide black etc., these pigment can make according to moulding color is compound
With reaching most preferably imitative flocking effect.
A kind of low smell, imitative flocking effect plant straw powder filling modified polypropylene material preparation method, it is specific to walk
Suddenly it is：
Acrylic resin, mineral powder, toughener, plant straw powder, antioxidant and the steady agent of light etc. are weighed in proportion, first
It is put into mixed at high speed machine and mixes 5-10min, then place into double screw extruder, processing temperature is 100-230 DEG C, main
Machine rotating speed is 300-500rpm.Finally, through sink cooling and pelleter pelletizing.
Compared with prior art, the present invention with following good effect：
1st, light modified polypropylene material is added to, with reference to texture instead of staple fibre using plant straw powder
Design has imitative flocking effect, and the hollow structure of straw powder generates smell suction-operated, not only reduces material smell, also
Light wheat fragrance type can be generated.The inside gadget product of the material alternative textile fabric cladding, not only auto parts and components
Producer saves production cost, and meets consumer significantly to automotive upholstery in smell and visual high request.
2nd, the plant straw powder amount added is less, it is not easy to and it is precipitated, no any influence is influenced on material physical property,
The requirement of auto parts and components can be reached, can be applied to the inside gadgets such as automobile stand column, door-plate.
Specific embodiment
