preparation example Construction

[0030] The above-mentioned automotive interior composite panel can be prepared by methods commonly used in the prior art, such as the preparation method of the automotive interior composite panel specifically includes:

[0031] a. Melting and extruding the above-mentioned automotive interior panel composition to obtain an automotive interior panel containing polypropylene and polyethylene terephthalate;

[0032] b. Laminate the automotive interior panels with non-woven fabrics.

[0033] Preferably, step a specifically includes: putting the automotive interior trim sheet composition into an extruder, setting the temperature of the extruder to 170-210°C, the temperature of the die head to 200-210°C, and the screw speed to 50-350 rpm Minutes for melt extrusion;

[0034] Step b is specifically as follows: the non-woven fabric and the automobile interior trim sheet prepared in step a are heat-melted and laminated together by a three-roll calender, the three rolls are fed from the ...

Embodiment 1

[0038] This example is used to illustrate the automobile interior trim sheet composition disclosed in the present invention.

[0039] 1. Preparation of automotive interior composite panel waste particles

[0040] Take 20 parts of copolymerized polypropylene, 40 parts of homopolypropylene, 0.4 parts of hindered phenol, 20 parts of ultrafine calcium carbonate, 4 parts of PP-g-MAH, and 2.6 parts of POE, and add the above components to the high-speed mixer (SHR-5A high-speed mixer produced by Zhangjiagang Hongji Machinery Co., Ltd.), mixed for 10 minutes to obtain a mixture.

[0041] Put the above mixture into the extruder (TSSJ25 twin-screw extruder produced by Chenguang Keqiang Company), set the temperature of the extruder to 190°C, the temperature of the die head to 200°C, the aspect ratio to 20, and the screw speed to 100 rpm / minute, carry out melt extruding, obtain the automotive interior trim sheet material sample;

[0042] The PET non-woven fabric is hot-melt-laminated ...

Embodiment 2

[0047] This example is used to illustrate the automobile interior trim sheet composition disclosed in the present invention.

[0048] 1. Preparation of automotive interior composite panel waste particles

[0049] The preparation method of waste granules was the same as in Example 1 to obtain waste granules A2. The difference is that in the waste granules A2, based on the weight of the waste granules, the polypropylene content is 70wt%, and the polyethylene terephthalate content is 30wt%.

[0050] 2. Preparation of automobile interior trim sheet composition

[0051] Based on the weight of the automotive trim panel composition to be prepared, 57.5 parts by weight of homopolypropylene, 0.25 parts by weight of hindered phenol (produced by Ciba), 0.25 parts by weight of phosphite (produced by Ciba), 42 Parts by weight of waste particles A2, the above-mentioned components are added to a high-speed mixer (the SHR-5A high-speed mixer produced by Zhangjiagang Hongji Machinery Co., Lt...
