Problems solved by technology

[0003] At present, the materials widely used in automotive interiors mainly include PVC artificial leather, PU artificial leather and fabrics. Although the performance of these materials can meet the current requirements of consumers, they cannot be recycled due to their heavy quality and strong odor. The problem has been complained and complained by more and more consumers, therefore, there is a need for a lightweight and environmentally friendly automotive interior material to solve the above problems

Embodiment 1

[0033] In this embodiment, light weight polyolefin foam and thermoplastic polyolefin elastomer (TPO) skin are compounded into environmentally friendly car interior artificial leather under high temperature conditions. The specific steps are as follows:

[0034] Step 1: surface-treat the lightweight polyolefin foam on a printing machine and coat it with paint to obtain a polyolefin foam semi-finished product. The relevant performance parameters of the above-mentioned lightweight polyolefin foam are shown in Table 1.

[0035] Step 2: TPO skin with a thickness of 0.50mm is produced by extrusion / calendering process in the extruder.

[0036] Step 3: Print the TPO skin obtained in the second step on the printing machine to print paint on the surface.

[0037] Step 4: Composite and emboss the polyolefin foam semi-finished product in the first step with the printed TPO skin described in the third step in the embossing machine to obtain lightweight polyolefin foam composite TPO skin pr...

Abstract

The invention discloses application of light polyolefin foam in environmentally friendly automotive interior decoration artificial leather. The light polyolefin foam is prepared from one or more of the following components: polypropylene and polyethylene and is prepared by the following steps: extruding the components, carrying out crosslinking, and carrying out high-temperature foaming, wherein parameters of the light polyolefin foam are as follows: the thickness is 0.50-6.00mm, the density is 35-100kg / m<3>, the normal temperature tensile strength is no less than 300kPa, the normal temperature elongation at break is no less than 150 percent, the atomization value is no larger than 0.5mg, and the burning rate is no larger than 200m / min. According to the environmentally friendly automotive interior decoration artificial leather prepared from the light polyolefin foam, the weight of the environmental-friendly automotive interior decoration artificial leather is obviously lowered compared with other similar automotive interior decoration artificial leather products; in the premise with same using area or using amount, the weight can be lightened by about 30 percent to the maximum, and the light polyolefin foam makes greater contribution to reduction of the weight of a whole automobile and energy consumption.

Description

technical field [0001] The invention belongs to the field of polymer materials, especially the field of automotive interior materials, especially the application of lightweight polyolefin foam in environment-friendly artificial leather for automotive interiors. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, and the number of small family cars has increased year by year. With the increase in the number of cars and the frequency of use, at the same time, in view of the increasingly stringent global requirements for environmental protection and energy conservation, people's awareness of environmental protection and energy is also increasing. It is increasing year by year, so consumers not only value the appearance of the vehicle when they buy a car, but also pay more attention to the fuel consumption of the vehicle itself and the corresponding environmental protection indicators. Therefore, light and environmentally friendl...
