The present invention proposes a kind of PP composite material and preparation method thereof.The PP composite material is used to fabricate
Inner container of icebox, so that scrappage of the inner container of icebox during the manufacturing is reduced, and inner container of icebox during user's use
The problem of cracking.The present invention also provides a kind of inner container of icebox and includes the refrigerator of the inner container of icebox, and the inner container of icebox is by upper

In embodiments of the present invention, the PP composite material by weight, including：80~100 parts of polypropylene；Mineral
5~30 parts of filler；0.1~0.5 part of age resister；0.1~3 part of dispersant；1~5 part of compatilizer.
Polypropylene has following three kinds：
(1), HOPP (PP-H), is polymerized by single propylene monomer, and vinyl monomer is free of in strand, because
The regularity of this strand is very high, therefore the crystallinity of material is high, impact property is poor.To improve the more crisp problem of PP-H,
Part material supplier is also adopted by the method for polyethylene and second the third glue blending and modifying to improve the toughness of material, but can not be from this
The long-term Heat-resistant stable performance of PP-H is solved in matter.HOPP intensity is preferable.
(2), atactic copolymerized polypropene (PP-R), by propylene monomer and a small amount of ethene (1-4%) monomer in heating, pressurization
Obtained with copolymerization under catalyst action, vinyl monomer is random, be randomly distributed in the long-chain of propylene.The random addition of ethene
The crystallinity and fusing point that reduce polymer, the impact, long-term resistance to hydrostatic pressure, long-term heat oxygen aging resistance and the tubing that improve material
The performance of the aspects such as machine-shaping.Long-term thermal stability, power of the indexs such as PP-R molecular chain structures, vinyl monomer content to material
Learn performance and processing characteristics suffers from directly influence.Distribution of the vinyl monomer in propylene molecules chain is more random, polypropylene
The change of energy is more significant.The good combination property of atactic copolymerized polypropene, intensity is high, rigidity is big, heat resistance is good, dimensional stability
Good, low-temperature flexibility is splendid (flexibility is good), and the transparency is good, and glossiness is good.
(3), block copolymerization polypropylene (PP-B)
Ethylene contents are higher, and generally 7~15%.But because two vinyl monomers in PP-B and three monomers are connected to one
During the probability for rising is very high, therefore explanation only exists block phase due to vinyl monomer, not by the regularity reduction of PP-H.Thus
The mesh for improving the performances of aspect such as PP-H fusing points, long-term resistance to hydrostatic pressure, long-term heat oxygen aging resistance and tubular object extruding shaping is not reached
's.The shock resistance of block copolymerization polypropylene preferably, improves again in a certain degree of rigidity.It is polyacrylic for three kinds common
It is same, the resistance to water soak of three, antiacid caustic corrosion, antilysis, inoxidizability difference is due to crystallization, polyacrylic receipts under high temperature
Shrinkage is at a relatively high, generally 1.8-2.5%.
Here, three kinds of polypropylene can be mixed with arbitrary ratio, for example, the one kind in three kinds of polypropylene is only chosen, or
Person chooses two of which, and three kinds of mixing can also be chosen certainly.
For three kinds of polypropylene, in order that its handling ease, and on the basis of not interfering with polyacrylic intensity, gather
The melt index of propylene should be difficult it is too high, be not easy to it is too low, here, described polypropylene is in 230 DEG C of temperature, weight 2.16Kg
Under the conditions of test melt index be 2g/10min~150g/10min, such as 3g/10min, 7g/10min, 10g/
10min、15g/10min、20g/10min、30g/10min、50g/10min、80g/10min、100g/10min、120g/
10min, 150g/10min etc..Certainly, melt index is too low, for example 3g/10min, 7g/10min, 10g/10min, can cause to gather
Acrylic composite is more crisp, and impact resistance is poor.If its melt index is higher, such as 100g/10min, 120g/10min,
150g/10min, in this way, PP composite material intensity can be caused relatively low, in process of production, refrigerator inner liner plates defect rate
It is higher.So, here, preferred molten index be 60g/10min~80g/10min, in this way, PP composite material have concurrently it is high-strength
Degree and impact resistance it is strong the characteristics of.
In addition, mineral filler can strengthen polyacrylic intensity, mineral filler described herein be calcium carbonate, barium sulfate,
One kind or its combination in talcum powder, wollastonite, whisker.After adding mineral filler in polypropylene, if mineral filler distribution is not
, then the intensity of PP composite material can be substantially reduced.Here, the addition of dispersant can uniformly divide mineral filler
Cloth, so as to avoid mineral filler localized clusters or the extremely low situation of local distribution amount from occurring.Described dispersant be PE waxes,
One kind or its combination in EBS, zinc stearate, calcium stearate.
Furthermore, it is old during processing or user's use that age resister can significantly slow down PP composite material
Change, described age resister is Hinered phenols antioxidant, phosphite ester kind antioxidant is a kind of or its combination.
Compatilizer refers to, by means of intermolecular bonding force, to promote incompatible two kinds of polymer to combine in one, and then
The auxiliary agent of the blend stablized.Compatilizer increased the compatibility of two kinds of polymer, and bonding force increases between making two kinds of polymer
Greatly, the structure of stabilization is formed, makes dispersed phase and continuous phase uniform.Why compatilizer can make the different polymer phase of two kinds of property
Rong Hua, because having the reason of the group that can be physically or chemically combined with two kinds of polymer respectively in the molecule thereof.
This, the compatilizer of addition is polypropylene grafted maleic anhydride, and the polypropylene grafted maleic anhydride is in 230 DEG C of temperature, weight
(GB) is tested under the conditions of 2.16Kg, its melt index is 2g/10min~150g/10min, for example, 3g/10min, 7g/
10min、10g/10min、15g/10min、20g/10min、30g/10min、50g/10min、80g/10min、100g/10min、
120g/10min, 150g/10min etc..Preferably, melt index is 60g/10min~80g/10min.
Carrying out chemical modification by polypropylene grafted maleic anhydride can usually assign its polyolefin many advantageous properties, for example
Their cementability, dyeability are improved, and these characteristics are heavily dependent on grafting rate.Here, in order that polypropylene is multiple
Condensation material has preferable cementability, and its grafting rate is 0.3%~2%.For example, 0.5%, 0.7%, 1.0%, 1.2%,
1.5%th, 1.8% etc..Here, for polypropylene grafted maleic anhydride, grafting rate is higher, cementability is stronger；Conversely, grafting
Rate is lower, and cementability is on the weak side.But meanwhile, if grafting rate is too high, the fragility of polypropylene composite can be caused to be lifted, its resistance to punching
Hitting property is reduced on the contrary, in this regard, in process of production, the improvement of its defect rate is general；In addition, when later stage user uses, ice
The low-temperature impact-resistant performance of case inner bag can also weaken.In consideration of it, grafting rate is 0.7%~1.2% preferable.
The sheet material for manufacturing inner container of icebox can according to demand add different toners, the demand different to meet user.
This, described toner can be one or more in titanium dioxide, ultramarine, ultramarine violet, iron oxide red, iron oxide yellow.
The present invention also provides a kind of preparation method of PP composite material, comprises the following steps：
A, the component of each proportioning of the PP composite material is added to be well mixed in mixer after discharge；
B, the mixture in step a is added to extruding pelletization in double screw extruder；Wherein, double screw extruder turn
Speed is set to 250r/min~500r/min, and each area's temperature setting scope is 160 DEG C~240 DEG C.
By each component according to correspondence proportion mix after, compatilizer by taking polypropylene grafted maleic anhydride as an example, anhydride group
In the presence of high temperature and screw rod shearing, can with polar group (- NH2 ,-OH) occur broad sense dehydration and form chemistry
Key, so as to incompatible polarity and apolar substance are carried out into chemical coupling.
