Abstract
The invention discloses a preparation method of a low-odor low-emission spraying-free aluminum powder master batch. The low-odor low-emission spraying-free aluminum powder master batch is prepared from the following raw materials in percentage by weight: 25-74.9% of low-molecular-weight polypropylene, 25-70% of aluminum powder, 0.1-2% of antioxidant and 0-3% of other assistants. By utilizing the lubricating property of the low-molecular-weight polypropylene and the excellent compatibility with the polypropylene, the prepared aluminum powder master batch improves the compatibility of the aluminum powder with the polypropylene material. The product has favorable odor and low total carbon emission amount, and can be used for substituting the traditional PE (polyethylene)-based aluminum powder master batch product with PE wax and OP wax.
Description
Technical field
The present invention relates to a kind of low smell, low distribute exempt from sandblast aluminium dust master batch and preparation method thereof, be that a kind of technique is simple, aluminium powder good dispersion, low smell, the low aluminium powder agglomerate preparation method distributed, can be used for the PE base aluminium powder master batch product of alternative traditional interpolation PE wax, OP wax.
Background technology
Polypropylene is one of five large class general-purpose plastics, due to its abundant raw material source, low price, be easy to machine-shaping, product high comprehensive performance, therefore purposes widely, become kind with fastest developing speed in resins for universal use, is widely used in inner and outer decorative parts of automobile product.
Current polypropylene material is used for fascia, door-plate, during the automotive trims such as handrail, due to the needs of surface color and outward appearance, usually need to spray paint, and spray paint and be unfavorable for the control of car load Air quality, therefore increasing part adopts and exempts from spray material, the spray coating polypropylene material of exempting from adding such as metallic color aluminium powder obtains and develops widely, but the interpolation due to pure metal aluminium powder is very difficult and dispersion is extremely uneven, be easy to cause product surface aberration, this has had a strong impact on the qualification rate of automotive upholstery, therefore all first make aluminium powder master batch to use, use PE wax simultaneously, traditional dispersion agents such as OP wax are produced aluminium powder master batch and product surface can be caused to be clamminess, product odour difference waits undesirable condition.Present automotive material requires more and more higher to the odor properties such as smell, therefore develop a kind of low smell, low distribute to exempt from spray material aluminium powder master batch significant.
Summary of the invention
The object of the present invention is to provide a kind of low smell, low distribute exempt from sandblast aluminium dust master batch, and this preparation method exempting from sandblast aluminium dust master batch, in actual applications, utilize the oilness of low-molecular-weight polypropylene and the consistency excellent with polypropylene, prepared aluminium powder master batch improves the consistency of aluminium powder with polypropylene material, the smell of product is good simultaneously, and total carbon emitting amount is low, can be used for the PE base aluminium powder master batch product of alternative traditional interpolation PE wax, OP wax.
Object of the present invention realizes mainly through following technical scheme.
Low smell, low distribute exempt from a sandblast aluminium dust master batch, form by the preparation of raw material of following weight percent meter:
Wherein, described low-molecular-weight polypropylene, its molecular weight is 10000 ~ 100000, and density is at 0.86 ~ 0.88g/cm
3.
Described aluminium powder is a kind of in pure aluminium powder and silver powder or the mixture of the two.
Described oxidation inhibitor is primary antioxidant and auxiliary anti-oxidant, and wherein primary antioxidant is selected from hindered phenol or sulphur ester antioxidant.Be 3114,1010 and DSTP in one or more; Auxiliary anti-oxidant selects phosphorite kind antioxidant.Be one or both in 618 and 168.
Other described additives are various lubricant, anti UV agent.
This low smell, the low preparation method exempting from sandblast aluminium dust master batch distributed, its step is as follows:
1, raw material is taken by weight ratio;
2, by the banburying 5 ~ 10 minutes in Banbury mixer of low-molecular-weight polypropylene, aluminium powder, oxidation inhibitor and other auxiliary agents;
3, the raw material that banburying is good is put into single screw extrusion machine extruding pelletization, screw speed is 180 ~ 600 revs/min, and temperature is 120 ~ 140 DEG C, a district, two 140 ~ 160 DEG C, districts, three 160 ~ 180 DEG C, districts, four 180 ~ 160 DEG C, districts; The residence time of whole extrusion is 1 ~ 2 minute, and pressure is 12 ~ 18MPa.
Aluminium powder master batch prepared by the present invention can avoid the use of the dispersion agent such as conventional P E wax, OP wax, improves smell and the total carbon emitting performance of aluminium powder master batch, obtained exempts from that spray coating polypropylene material appearance is stable, odor dispersion excellent property.
Concrete embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
In embodiment and comparative example composite-material formula, polypropylene is the Co-polypropylene that Shanghai Petrochemical Co. Ltd. produces, and commodity are called M2600R, and its melt flow rate (MFR) is 26g/10min (test condition: 230 DEG C × 2.16Kg); Described low-molecular-weight polypropylene is the L-MODU that Japanese bright dipping company produces
tMlow-molecular-weight polypropylene, commodity are called S600, and density is at 0.87g/cm
3; Described aluminium powder is aluminium silver powder, and production company is German eckart company, and commodity are called PCR214.PE wax provides for Qingdao Sai Nuo company, and model is 118C; Linear low density polyethylene LLDPE is the LLDPE-8320 that China Petrochemical Industry's Zhenghai refinery is produced; The DSTP that primary antioxidant selects ICE company of Britain to produce, chemistry thio-2 acid octadecyl ester by name, and 3114 of the production of Ciba company, chemistry 3,5-di-tert-butyl-4-hydroxyl benzyl diethyl phosphoric acid by name.Auxiliary anti-oxidant is 168 of the production of Ciba company, and chemical name is three (2,4-di-t-butyl benzyl) phosphorous acid ester.
All components to be added in Banbury mixer banburying 5 ~ 10 minutes.The raw material mixed is put into single screw extrusion machine extruding pelletization, and screw speed is 180 ~ 600 revs/min, and temperature is 120 ~ 140 DEG C, a district, two 140 ~ 160 DEG C, districts, three 160 ~ 180 DEG C, districts, four 180 ~ 160 DEG C, districts; The residence time of whole extrusion is 1 ~ 2 minute, and pressure is 12 ~ 18MPa.
Performance evaluation and the standard of implementation:
Odor properties is carried out according to popular PV3900, and lower grade smell is better.Distribution performance total carbon characterizes, and carries out according to popular PV3341, and test value is more low better.
Example formulations and properties test result are shown in following each table:
Table 1 is example composition formula (% by weight).
The particulate material of granulation will be completed as stated above as drying in the air dry oven of 100 DEG C 2 ~ 3 hours, and then dried pellet is added in polypropylene with 3wt%, 4wt%, injection moulding model after mixing, test smell and total carbon value; Simultaneously composition G, H also re-packs smelling the odour and survey total carbon value.
As can be seen from the contrast of embodiment 1 ~ 4, low-molecular-weight polypropylene is adopted to do the aluminium powder master batch of base material, its smell and total carbon emitting are all significantly better than traditional PE base material, traditional mode odor effect adding PE wax is poor, and adopt low-molecular-weight polypropylene to be that base material just can obtain good low odor effect without the need to adding dispersion agent, and total carbon emitting is also better; The contrast of all experiments can be found out, adopts low-molecular-weight polypropylene as base material, prepares low smell, the low sandblast aluminium dust master batch of exempting from distributed has broad application prospects.
