Description
Technical Field

Background
Polypropylene (PP) has the advantages of low density, easy processing, excellent mechanical properties and the like, and has been widely applied to the fields of automobile industry, household appliances and machinery. For the automobile industry, polypropylene is mainly applied to automobile interior and exterior parts, interior parts such as instrument panels, door panels, upright posts and the like, and exterior parts such as bumpers, mud guards, guide plates and the like. With the annual promotion of energy conservation and emission reduction and automobile light weight, resin tail gates and gate outer plates also provide a full-resin design scheme, so that low-linear expansion coefficient polypropylene is developed to become a new hot field.
In order to reduce the linear expansion coefficient of the polypropylene material, long glass fiber reinforced PP materials LFT-PP have been developed, wherein the LFT-PP material has low linear expansion coefficient, high strength and strong damage resistance and is generally used as a structural support, such as a new energy vehicle cabin cover inner plate framework, a back door inner plate framework and the like. However, in order to meet the appearance requirement, the outer plate material is generally mineral filled PP, and in order to be well assembled with the long glass fiber reinforced material of the inner plate, the linear expansion coefficient must be close to that of the long glass fiber reinforced material, so that the outer plate material must use a low linear expansion coefficient PP. And in specific application, certain adhesive strength performance needs to be ensured so as to meet the application requirements of the fields of back door inner plate frameworks and the like.
The prior art discloses a polypropylene composition with low linear expansion coefficient, which comprises the following components in percentage by weight: 40 to 70 percent of polypropylene resin, 10 to 30 percent of elastomer, 5 to 30 percent of filler with high length-diameter ratio, 0 to 20 percent of other inorganic fillers, 0.5 to 10 percent of compatilizer and 0.05 to 5 percent of other additives. The polypropylene composition adopts high length-diameter ratio (HAR) inorganic filler for filling and reinforcing or adopts high length-diameter ratio inorganic filler and common inorganic filler for compounding and filling and reinforcing, and then compatilizer is added for compound modification, so that the plastic part obtained by injection molding of the polypropylene composition has low linear expansion coefficient, good dimensional stability in high-low temperature circulation, and the product has nearly equal linear expansion coefficient in the injection molding flow direction (FD or MD) and the vertical injection molding flow direction (TD). The low linear expansion coefficient polypropylene composition, while improving the dimensional stability of the polypropylene composition, does not improve the adhesive properties of the polypropylene material.
Disclosure of Invention
The invention aims to overcome the defect and the defect of poor dimensional stability and adhesive property of the traditional polypropylene composition, and provides a polypropylene composition, wherein the dimensional stability and the adhesive property of the polypropylene composition are improved by the synergistic effect of specific addition of basic magnesium sulfate whisker, a toughening agent, a nucleating agent and other components.
It is another object of the present invention to provide a method for preparing a polypropylene composition.
It is a further object of the present invention to provide the use of a polypropylene composition in the manufacture of automotive and household parts.
The above object of the present invention is achieved by the following technical scheme:
the polypropylene composition comprises the following components in parts by weight:
40 to 58 parts of polypropylene, 13 to 26 parts of toughening agent, 25 to 40 parts of talcum powder, 1 to 6 parts of basic magnesium sulfate whisker, 0.1 to 0.4 part of nucleating agent and 0 to 1 part of other additives,
wherein, the mass flow rate of the melt is 70-150 g/10min under the load of 2.16kg at 230 ℃, and the detection standard is ISO 1133-1-2011;
the mass flow rate of the melt is 0.5-6 g/10min under the load of 2.16kg at 190 ℃, the detection standard is ASTM D1238-2013,
the length-diameter ratio of talcum powder is more than or equal to 10:1.
The following description is needed:
the parts by weight of the components in the polypropylene composition of the present invention are also critical, and the linear expansion coefficient of the polypropylene composition is significantly reduced when the talc content is increased. The basic magnesium sulfate whisker belongs to inorganic filler, has low linear expansion coefficient, has higher length-diameter ratio and specific surface area, has higher contact area with PP, and can limit the dimensional change of peripheral PP when the temperature is changed, thus being beneficial to cooperatively reducing the linear expansion coefficient of the polypropylene composition. Also, lower levels of toughening agents can result in materials with higher coefficients of linear expansion.
According to the invention, through cooperative control of the components, talcum powder with high length-diameter ratio and a nucleating agent are used, so that the linear expansion coefficient of the polypropylene composition is further effectively reduced, and the dimensional stability of the material is improved.
The invention adopts high-flow polypropylene and adds nucleating agent to improve the crystallinity of the material, so as to form alpha crystal form, increase the tensile strength of the material, improve the anti-damage capability and be more beneficial to improving the viscose performance. Compared with the round talcum powder particles with small length-diameter ratio, the talcum powder particles with small length-diameter ratio have the advantages that the surface property of the polypropylene composition is improved during viscose, the surface damage and whitening are not easy to cause, and the viscose property is further improved.
Wherein, the melt mass flow rate of the polypropylene and the toughening agent can ensure the dimensional stability of the polypropylene composition, and is more beneficial to processing and forming large-size plastic parts. Too much or too little toughening agent can reduce the shearing strength of the adhesive, and good adhesive performance can not be achieved
The polypropylene composition of the invention can obviously reduce the linear expansion coefficient through the synergistic effect of the components, so that parts are equivalent to steel, aluminum alloy or long glass fiber reinforced PP materials, and the polypropylene composition has very good adhesive property, is suitable for being applied to the fields of automobile parts and household appliances, and can be used for preparing automobile parts such as instrument boards, door plates, upright posts, bumpers, mud guards, guide plates, inner plate frameworks of new energy automobile cabin covers, inner plate frameworks of back tail doors and the like, and household appliances such as electric rice cooker covers, vehicle-mounted refrigerator bases, air conditioner air outlet cover plates, pet drinking bowl bases and the like.

In a specific embodiment, in order to further improve the dimensional stability of the polypropylene composition, it is preferable that the talc has an aspect ratio of (12 to 15): 1.
In a specific embodiment, in order to further improve the CLTE stability performance of the polypropylene composition, it is preferred that the polypropylene has a melt mass flow rate of 90 to 120g/10min at 230 ℃, under a load of 2.16kg, detection standard ISO 1133-1-2011.
In particular embodiments, to further improve the CLTE isotropic differential properties of the polypropylene composition, the toughening agent preferably has a melt mass flow rate of 1 to 4g/10min at 190 ℃, under a 2.16kg load, test standard ASTM D1238-2013.
