Example Embodiment

[0022] The present invention will be further explained below through specific embodiments.

[0023] The technical solution provided by this embodiment is: a low-temperature resistant reinforced PP composite material, which is composed of the following components by mass percentage: homopolymer PP accounts for 25%-40%, copolymer PP accounts for 30%-49%, talcum powder and Cold resistant agents account for 15%-25%, and antioxidants, lubricants and coupling agents are the balance.

[0024] Wherein, the homopolymer PP adopts T30S.

[0025] Wherein, the copolymerized PP adopts F800E.

[0026] Wherein, the cold hardening agent is dioctyl adipate, diisodecyl adipate, dioctyl azelate or dioctyl sebacate.

[0027] Among them, the antioxidant uses tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid] pentaerythritol ester.

[0028] The preparation method of the above-mentioned low-temperature resistant reinforced PP composite material provided in this embodiment includes the following...

Abstract

The invention belongs to the field of plastic modification technology and especially relates to a low temperature-resistant reinforced PP composite material and a preparation method thereof. The PP composite material comprises the following components by mass: 25 to 40% of homopolymerized PP, 30 to 49% of copolymerized PP and 15 to 25% of talcum powder and a cold resistant agent, with the balance being an anti-oxidant, a lubricant and a coupling agent. The preparation method comprises the following steps: blending; extrusion; and granulation. The composite material provided by the invention can maintain good toughness at low temperature conditions and meets requirements on usage of the PP composite material at a low temperature.

Description

technical field [0001] The invention belongs to the technical field of plastic modification, and in particular relates to a low-temperature-resistant reinforced PP composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a general-purpose plastic resin with a wide range of sources and low prices, and has a very wide range of uses. It has high crystallinity and regular structure, so it has excellent mechanical properties. The absolute value of the mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety in plastic materials, and its tensile strength can only reach 30 MPa or a slightly higher level. Polypropylene with a larger isotactic index has higher tensile strength, but as the isotactic index increases, the impact strength of the material decreases, but it does not change after falling to a certain value. [0003] Temperature and loading rate have a great infl...
