Description
Technical Field
The application relates to the field of polypropylene compositions, in particular to a polypropylene composition for a high-weather-resistance high-flame-retardance injection molding material and a polypropylene injection molding material.
Background
Polypropylene, PP for short, is a thermoplastic synthetic resin with excellent performance, is colorless semitransparent thermoplastic light general plastic, and is usually molded in an injection molding mode. Polypropylene has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties, good high abrasion resistance processability, etc., and has been developed and used in various fields.
However, polypropylene is inferior in flame retardancy and weather resistance. In the related research, a large amount of flame retardant and antioxidant are generally added into polypropylene, so that the flame retardant grade of the polypropylene reaches V0 grade, and delta E is less than or equal to 7. However, the addition of flame retardants and antioxidants to polypropylene results in a decrease in the gloss of the polypropylene below 75.
Disclosure of Invention
In order to improve the flame retardance and weather resistance of the polypropylene injection molding material and ensure the glossiness of the polypropylene injection molding material, the application provides a polypropylene composition for the high weather resistance and high flame retardance injection molding material and the polypropylene injection molding material.
In a first aspect, the application provides a polypropylene composition for a high weather-resistant high flame-retardant injection molding material, which comprises, by weight, 60-90 parts of polypropylene, 8-15 parts of fluorine-containing silane, 1-5 parts of flame retardant, 0.1-0.2 part of copper harm inhibitor, 0.1-0.5 part of processing aid and 0.3-0.5 part of antioxidant.
The flame retardant and the antioxidant are added into the polypropylene to prepare the polypropylene injection molding material, so that the flame retardant grade and the weather resistance of the polypropylene injection molding material can be improved, but the addition of the flame retardant and the antioxidant can lead to the reduction of the glossiness of the polypropylene injection molding material. In order to ensure the glossiness of the polypropylene injection molding material, it is easy to think that the amount of the flame retardant and the antioxidant is reduced, but the reduction of the flame retardant and the antioxidant inevitably leads to the reduction of the flame retardant property and the weather resistance of the polypropylene injection molding material.
In the application, through the interaction of the polypropylene, the fluorine-containing silane, the flame retardant and the antioxidant, the glossiness of the polypropylene injection molding material can be ensured, and the flame retardant grade and the weather resistance of the polypropylene injection molding material can be improved under the condition that the flame retardant and the antioxidant are used in a small amount. When the polypropylene, the fluorine-containing silane and the flame retardant are compounded according to (60-90 parts)/(8-15 parts)/(1-5 parts), the flame retardant grade of the polypropylene injection molding material is V0 grade, delta E is less than or equal to 3, and the glossiness is more than 75.
In some embodiments, polypropylene may be used in an amount of 60 parts, 65 parts, 70 parts, 72 parts, 75 parts, 80 parts, 85 parts, 90 parts.
In some embodiments, the fluorosilane may be used in an amount of 8, 9, 10, 11, 12, 13, 14, 15 parts.

By adopting the technical scheme, when the polypropylene injection molding material is prepared, the consumption of polypropylene and fluorine-containing silane is increased, the consumption of flame retardant and antioxidant is reduced, the flame retardant grade of the polypropylene injection molding material is V0 grade, delta E is less than or equal to 3, and the glossiness is gradually improved. When the consumption of the flame retardant is 1 part, the consumption of the polypropylene and the fluorine-containing silane is continuously increased, the consumption of the polypropylene is more than 90 parts, the consumption of the fluorine-containing silane is more than 15 parts, the flame retardant grade of the polypropylene injection molding material is V2 grade, delta E is less than or equal to 2.5, and the glossiness is less than 90. When the consumption of the flame retardant is 1 part, the consumption of polypropylene and fluorine-containing silane is reduced, the consumption of polypropylene is less than 60 parts, the consumption of fluorine-containing silane is more than 8 parts, the flame retardant grade of the polypropylene injection molding material is V0 grade, delta E is less than or equal to 4.5, and the glossiness is below 74.

The inorganic hydroxide flame retardant has the advantages of easy treatment, relative innocuity, no generation of toxic and corrosive gases, and the like, and is more important to be cheaper than halogen and phosphorus flame retardant systems.

Preferably, the antioxidant comprises an antioxidant, an ultraviolet absorber.
In the application, the antioxidant and the ultraviolet absorber are added into the polypropylene as functional raw materials, so that the antioxidant capacity of the polypropylene injection molding material can be improved, and the weather resistance of the polypropylene injection molding material can be further improved.

Performance test
The above examples 1 to 17 and comparative examples 1 to 6 were subjected to flame retardance, weather resistance and gloss tests, the specific test results being shown in Table 3, wherein the weather resistance test was conducted in reference to GB/T16422.4-2014 "light Source Exposure test method for plastics laboratory", and the flame retardance was in reference to UL94 standard, 0.8mm standard test piece.
TABLE 3 experimental test results
As can be seen from the combination of examples 1 to 17 and comparative examples 1 to 6 and Table 3, the polypropylene injection molding materials prepared in examples 1 to 17 of the present application all have a flame retardant rating of V0, a DeltaE.ltoreq.3 and a gloss of 75 or more. In particular, the polypropylene injection molding material prepared in example 3 has a flame retardant rating of V0, a DeltaE of 1.5 or less and a gloss of 92.
It can be seen from the combination of examples 1-3 and Table 3 that as the amounts of polypropylene and fluorosilane are increased, the amount of flame retardant is decreased, the flame retardant rating of the polypropylene injection molding material remains unchanged, the weather resistance is decreased, and the gloss is increased. The reduction of the amount of the flame retardant does not reduce the flame retardant grade of the polypropylene injection molding material, but rather increases the glossiness and the weather resistance.
It can be seen from the combination of example 3 and comparative examples 1-2 and Table 3 that when the amount of flame retardant was kept constant, the amounts of polypropylene and fluorosilane were further increased, and the weather resistance and gloss of the polypropylene injection molding material were slightly lowered, and the flame retardant rating was V2 only. When the consumption of the flame retardant is kept unchanged, the consumption of the polypropylene and the fluorine-containing silane is reduced, the flame retardant grade of the polypropylene injection molding material is V0 grade, but the delta E of the polypropylene injection molding material is less than or equal to 4.5, and the glossiness is only 74.
As can be seen from the combination of example 3 and comparative example 3 and Table 3, the amount of fluorosilane used in the preparation of the polypropylene injection molding material was 0kg, the flame retardant rating of the polypropylene injection molding material was V2 rating, ΔE was 6 or less, and the gloss was only 70.
As can be seen from the combination of examples 3 to 7 and examples 10 to 14 and Table 3, when the polypropylene injection molding material was prepared, the flame retardant rating of the polypropylene injection molding material remained unchanged and the weather resistance and gloss were gradually lowered as the melt flow rate of the polypropylene was gradually lowered while the amounts of the raw materials such as polypropylene, fluorosilane and flame retardant were unchanged.
As can be seen from the combination of the example 3 and the comparative examples 4-5 and the combination of the table 3, the amounts and types of the polypropylene and the fluorine-containing silane are unchanged, when the amount of the flame retardant is 6 parts, the flame retardant grade of the polypropylene injection molding material is V0 grade, delta E is less than or equal to 1.5, but the glossiness is lower, and the glossiness cannot meet the use requirement; when the amount of the flame retardant is 0.5 part, the glossiness of the polypropylene injection molding material is 85, delta E is less than or equal to 1.8, but the flame retardant grade is V1, and the use requirement cannot be met.
It is to be understood that the above embodiments are merely illustrative of the exemplary embodiments employed to illustrate the principles of the present application, however, the present application is not limited thereto. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the present application, and are also considered to be within the scope of the invention.
