Abstract

The invention relates to the field of preparation of automotive interior materials, and particularly discloses a high-modulus automotive interior flame-retardant PP material and a preparation method thereof. The high-modulus automotive trim flame-retardant PP material is prepared from the following raw materials in parts by weight: 70-80 parts of polypropylene PP particles, 10-16 parts of an inorganic composite flame retardant, 6-8 parts of a linear ethylene-octylene copolymer, 10-15 parts of talcum powder and 1.2 parts of an antioxidant, wherein the inorganic composite flame retardant is formed by compounding modified nano aluminum hydroxide, micron magnesium hydroxide and zinc borate in a certain proportion, the synergistic effect of the modified nano aluminum hydroxide, the micron magnesium hydroxide and the zinc borate is fully exerted, and the flame retardant effect of the automotive trim PP material is improved; the preparation method comprises the following steps: mixing the raw materials according to the corresponding weight, extruding, melting, granulating and drying to obtain the automotive trim PP flame-retardant material. The automotive trim PP material disclosed by the invention has the advantages of excellent flame retardance and high modulus; in addition, the preparation method has the advantages of being simple in preparation process and suitable for industrial production.

Description

technical field [0001] The application relates to the field of preparation of automotive interior materials, more specifically, it relates to a high-modulus automotive interior flame-retardant PP material and a preparation method thereof. Background technique [0002] Car interior mainly refers to the car products used in car interior modification, involving all aspects of car interior, such as car steering wheel cover, car seat cushion, car floor mat, car perfume, car pendant, interior decoration, storage box, etc. [0003] The flame retardant requirements for automotive interior parts are gradually becoming stricter. At the same time, the VOC requirements of automotive interior parts have become a problem that all automotive OEMs must solve. Automotive interior parts, such as door panels, pillars, threading pipes, handles, ceilings, center consoles, etc., are mostly made of PP materials. The flame retardant of PP materials is mostly a halogen-containing flame retardant s...
