Problems solved by technology

In this invention, non-crosslinked polyolefin is used to replace pre-crosslinked polyolefin. Compared with pre-crosslinked polyolefin, non-crosslinked polyolefin has relatively poor modulus, strength, thermal properties and thermomechanical properties. The application of the polyolefin film; this method is a low-cost method, not suitable for high quality requirements

[0049] Each component was mixed according to the formula amount of Examples 1-4, and a TPV film was obtained by calendering.

[0050] The TPV film is either not subjected to radiation cross-linking treatment, or is subjected to positive mold molding after radiation cross-linking with 10kGy, 60kGy, 130kGy, or 200kGy. The molding effect, surface pattern, and tensile strength change of the obtained film (compared with the sample without radiation treatment as 100%) were compared, and the results are shown in Tabl...

Embodiment 5

[0055] A TPV material for automobile interior decoration, comprising 100 parts by weight of TPV and 1 part by weight of a crosslinking agent.

[0056] The preparation method of above-mentioned TPV material is:

[0057] (1) Obtain TPV film by calendering;

[0058] (2) Carry out surface embossing and surface coating treatment processes on the TPV film obtained in step (1), and then use electron beams to perform radiation crosslinking. The radiation dose of the electron beams is 200 kGy to obtain the TPV material for automotive interior decoration.

Embodiment 6

[0060] A kind of TPV material for automotive interior, comprising by weight parts:

[0061]

[0062] The preparation method of above-mentioned TPV material is:

[0063] (1) Obtain TPV film by calendering;

[0064] (2) Carry out surface embossing and surface coating treatment processes on the TPV film obtained in step (1), and then use electron beams to carry out radiation crosslinking. The radiation dose of electron beams is 1 kGy to obtain the TPV material for automotive interiors.

Abstract

The invention relates to TPV (Thermoplastic Vulcanizate) material for automobile interior trim. The TPV material comprises the following material in part by weight: 80 to 120 parts of TPV, 0 to 15 parts of cross-linking agent, 0 to 10 parts of nucleating agent, 0 to 5 parts of antioxidant, 0 to 5 parts of light stabilizer and 0 to 5 parts of coloring agent. The invention also discloses a preparation method of the TPV material. The TPV material conducted to radiation crosslinking has the advantages that the high temperature resistance and the ageing resistance are improved, and melt viscosity is increased and molecular chains are difficult to move and are not easy to deform because of crosslinking and involvement of the molecular chains during secondary machine shaping at high temperature, so that the conservation degree of patterns of the TPV material is good.

Description

technical field [0001] The invention relates to an automobile interior material, in particular to a TPV (dynamically cross-linked thermoplastic elastomer) material for an automobile interior and a preparation method thereof. Background technique [0002] With the increase of global car ownership and the expansion of the domestic auto market, the market for automotive interior materials is also growing. The parts that use composite materials on automobiles are mainly dashboards, door guards, roof inner guards, carpets, seats and parcel shelf guards. They are basically made of skin (plastic, fabric, carpet), sound insulation and vibration damping parts. (foam or fiber) and skeleton parts, this form of parts not only meets certain functions, but also makes people feel comfortable and beautiful, and because of the simple production process, low cost and strong applicability of this material, it develops relatively rapidly , it will be the main development direction of automotiv...
