Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a polypropylene composite material and a preparation method and application thereof.
Background
With the increasing severity of national government regulations on automobile environmental protection requirements, automobile interior trim material odor standards are formulated by automobile host factories for standardizing parts or materials which can influence automobile cockpit odor, such as PV3900 of mass automobiles for sampling and odor assessment requirements on parts with different sizes of automobile interior trim.
With the continuous improvement of the living standard of people, the requirements on mechanical property, processability, weather resistance and the like of automotive interior materials (such as automotive polypropylene composite materials) are continuously improved, the automobile interior materials have good low volatility, the requirements on odor are higher and higher, and the odor requirement becomes one of the factors for evaluating the product quality of people. The odor generation and release in the polypropylene composite for vehicles is mechanically solid adsorption (endothermic reaction) and desorption (exothermic reaction) of gas. The organic small molecules generated in the raw material polymerization and modification process of the polypropylene composite material are adsorbed in the material and slowly released along with the change of the external environment temperature and pressure. Odor generation is the process by which odors desorb from the solid interface.
For a certain system of adsorbent and adsorbate, there is a relationship between the adsorption amount and the temperature and pressure, and Langmuir theories believe that when adsorption equilibrium is reached, the adsorption amount is a function of the temperature and adsorbate pressure. When the temperature T is constant, the saturated adsorption quantity and the pressure are positively correlated, when the pressure is high, the adsorption quantity is close to the limit value VM, and when the pressure is low, the adsorption quantity is proportional to the pressure; when the pressure is constant, the adsorption amount and the temperature are inversely related, that is, the higher the temperature is, the less the adsorption amount is, the lower the temperature is, and the higher the adsorption amount is. The relationship between the adsorption amount and the temperature explains the phenomenon that the smell of the automobile is less in winter than in summer, and the smell after the automobile is exposed to the sun in summer is more serious than in normal environment.
In addition, in order to meet the standard requirements of automobiles, various auxiliary agents such as inorganic fillers, elastomers, colorants, antioxidants, scratch-resistant agents and the like are often added into the automobile polypropylene composite material, and the substances volatilize themselves or residual impurities to generate pungent odor.
In the prior art, in order to reduce the odor of the polypropylene composite material, the following measures are mainly adopted, namely 1, low-odor substitutes are used for replacing the unpleasant additives; 2. adding an odor adsorbent, including chemical reaction and physical adsorption methods, to reduce the odor of the material; 3. after the modified material is prepared, the odor is reduced by adopting post-treatment modes such as baking and the like. However, the existing polypropylene composite material for vehicles still has strong odor and does not meet the requirements of people.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a polypropylene composite material, a preparation method and application thereof. The invention solves the odor problem of the polypropylene composite material from the thermodynamic source, can adsorb small molecular substances with different particle diameters or different types, so that the odor of the composite material is weaker, and the polypropylene composite material has better cooling performance.

TABLE 3 Table 3
TABLE 4 Table 4
From the data in tables 3 and 4, it can be seen that the polypropylene composites prepared from different PP resins in examples 1-6 have a low odor and a good cooling performance, and the PP resins in examples 1-4 are more advantageous for cooling the polypropylene composites. Compared with examples 5-6, the PP resin in example 1 adopts a hydroxide degradation method to adjust the molecular weight, and the prepared polypropylene composite material has better cooling performance and weaker smell, which indicates that the adoption of the hydroxide degradation method to adjust the molecular weight of the PP resin is beneficial to reducing the smell and improving the cooling performance.
The polypropylene composite materials prepared by using chromium cobalt blue and nickel titanium yellow as infrared reflection pigments in examples 7-8 are lower in cooling performance than example 1, and the smell of the composite materials is stronger than that of example 1, which shows that the cooling performance and low smell performance brought by the infrared reflection pigment IRP-B are better than those brought by chromium cobalt blue and nickel titanium yellow, and the cooling performance and low smell performance brought by nickel titanium yellow are better than those of chromium cobalt blue.
The titanium dioxide with different weight portions is added to the composite material of the embodiment 9-11, so that the temperature of the surface of the composite material can be effectively reduced, and the cooling performance of the material is improved, wherein the cooling performance of the composite material of the embodiment 10-11 is better than that of the embodiment 1 and the embodiment 9.

The polypropylene composite material of example 15 is added with three infrared reflection pigments, and the effect of reducing the surface temperature of the polypropylene composite material is better than that brought by adding two infrared reflection pigments, the main reflection peak wavelengths of the various infrared reflection pigments are different, and the compounding of the various reflection pigments can reflect most of the energy of the wavelengths, so that the cooling performance of the composite material is improved.

The polypropylene prepared by adding the ordinary carbon black in comparative example 1 has a higher temperature than the material of example 1, and the material of comparative example 1 has a higher temperature than that of comparative example 5, which means that the carbon black can absorb heat and has a negative effect on lowering the surface temperature of the color plate.
Comparative example 2 is a resin of ordinary type, and comparative examples 1 to 5 show that ordinary resins have a lower cooling effect than resins of controlled molecular weight.
Comparative example 3 is a polypropylene composite material using zinc oxide, comparative example 1 shows that zinc oxide has a lower effect on reducing the surface temperature than an infrared reflective pigment, and comparative example 5 shows that zinc oxide is added slightly better than it is not.
