Embodiment Construction

[0028] Such as figure 1 As shown, an environment-friendly TPO automotive interior material includes a TPO surface layer 3, a polypropylene foam layer 4 composited with the TPO surface layer, and the TPO surface layer 3 is also covered with a surface treatment agent layer 1 and a bottom surface treatment agent from top to bottom. Layer 2. Polypropylene foam layer 4 is coated with polyurethane adhesive 5 on the back. Among them, the surface treatment agent is water-based or solvent-based two-component polyurethane or polyurethane-polycarbonate; the bottom surface treatment agent is solvent-based or water-based two-component polyurethane or polyurethane-polycarbonate.

[0029] The thickness of the polypropylene foam layer of the present invention has four specifications of 1.0, 1.5, 2.0, 2.5, and 3.0 mm, the width is from 550 to 1350 mm, and the expansion ratio is 15 times or 20 times or 25 times or 30 times. It depends on different usage locations and usage requirements.

Abstract

The invention provides an environment-friendly thermoplastic polyolefin (TPO) auto interior material comprising a TPO surface layer, and a polypropylene foam layer which is compounded with the TPO surface layer, wherein the TPO surface layer is formed by semi-crosslinked TPO, polypropylene, polyethylene, a light stabilizer, an antioxidant, a fire retardant, a filler, an extinction material, a scratch resistant agent and a pigment. The TPO auto interior material disclosed by the invention has the advantages of being good in decorative property, environment-friendly and recoverable, low in odor, low in haze, high and low temperature resistant, weather-resistant, free of separated bloom, good in machinability, high in qualification rate, low in cost, and high in bonding strength with a skeleton, and still can keep good matting property and scratch resistance after being scrubbed.

Description

technical field [0001] The invention relates to an environment-friendly interior decoration material, in particular to a TPO automobile interior decoration material and a preparation method thereof. Background technique [0002] Automotive interior materials are mainly composed of instrument panels, door panels, pillars, seats, ceilings, sun visors, side panels and other components. With the enhancement of people's awareness of environmental protection, the internal quality of automotive interior materials, such as environmental protection recycling, odor, haze, high and low temperature resistance, aging resistance, weather resistance and other requirements are becoming more and more stringent. The appearance of these parts has a common feature, the surface has decorative patterns, and the brightness tends to be matted. There are two kinds of soft and hard touch. Taking the instrument panel as an example, it can be divided into two types: hard instrument panel and soft ins...
