Problems solved by technology

[0005] There are also reports on lightweight TPO automotive interior materials, such as a lightweight and environmentally friendly automotive interior material and its preparation process disclosed in Chinese patent CN109910411A. , the sponge layer, the base cloth layer and the lower surface treatment agent layer, which are formed by first forming the TPO skin layer, the sponge layer and the base cloth layer respectively, and then bonding the base cloth layer and the sponge layer by an adhesive, and then by bonding The TPO skin layer is bonded to the base fabric layer with a special agent, and then the upper surface and the lower surface are treated. The process and formula are extremely complicated and the cost is high.
And the car interior material is only used for manual coating process, not for adsorption process

Abstract

The invention relates to a novel safe environment-friendly lightweight automotive interior material and a preparation method thereof. The automotive interior material comprises a surface treatment layer, a TPO / TPU blended layer, a TPO foaming layer, a polypropylene foaming layer and a back treatment layer which are sequentially arranged. The TPO / TPU blended layer comprises the following raw materials in parts by weight: 90-95 parts of first TPO particles, 8-10 parts of a modified TPU material, 0-0.5 part of a temperature rise inhibiting material, 0-5 parts of a first auxiliary agent and 4-10 parts of a first pigment; and the TPO foaming layer comprises the following raw materials in parts by weight: : 90-95 parts of second TPO particles, 0.1-2.5 parts of a foaming agent, 0-5 parts of a second auxiliary agent and 4-10 parts of a second pigment. According to the automotive interior material, the TPO / TPU blended layer and the TPO foaming layer are adopted to replace a TPO layer of an existing automotive interior material, under the condition that the total thickness of the TPO / TPU blended layer and the TPO foaming layer is consistent with the thickness of the TPO layer, the weight of the automotive interior material is far lower than that of the existing TPO automotive interior material, the strength is not greatly influenced, and the light weight of the automotive interior material is really achieved.

Description

Technical field [0001] The invention belongs to the technical field of automotive interior, and specific relates to a new type of safe and environmentally lightweight automotive interior material and its preparation method thereof. Background technique [0002] In 1886, the world's first internal combustion engine power vehicle was born, lightweight, and safety and environmental protection has always been chasing. Looking back at the history of the car for 132 years, light weight, safe and environmentally friendly, is still slow. [0003] The existing lightweight car interior materials are commonly used in PVC, but PVC materials are difficult to meet the requirements in safety and environmental protection. Other lightweight materials such as PU materials, their production process and formulations are extremely complicated, high cost, only very few partial luxury cars. [0004] Today, more and more low-end cars are loved by consumers, and the interior materials are also very grade...
