Lightweight environment-friendly automobile interior material and preparation process thereof

Abstract

The invention discloses a lightweight environment-friendly automobile interior material and a preparation process thereof. The lightweight environment-friendly automobile interior material comprises an upper surface treatment agent layer, a TPO skin layer, a sponge layer, a base cloth layer and a lower surface treatment agent layer, wherein the sponge layer is arranged on the base cloth layer; thelower surface treatment agent layer is arranged below the base cloth layer; the TPO skin layer is arranged on the sponge layer; the upper surface treatment agent layer is arranged on the TPO skin layer. The TPO skin layer is easy to recover, resistant to high and low temperatures and low in odor and haze, produces hydrocarbons after combustion, and meets the requirement of environmental protection. The sponge layer enables automobile interior trim to have certain elasticity, and the base cloth layer enables the automobile interior trim to have certain thickness and has lower preparation costthan the TPO skin layer, the upper surface treatment agent layer and the lower surface treatment agent layer enable the prepared automobile interior trim to have certain bacteria and corrosion resistance, flame retardancy, abrasion resistance, oxidation resistance and sun protection.

Description

technical field [0001] The invention belongs to the field of automotive interior parts and manufacturing methods thereof, in particular to a lightweight and environment-friendly automotive interior material and a preparation process 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 tw...

Problems solved by technology

The disadvantage of this material is that more fillers are added, which increases the density of the material while improving the rigidity and dimensional stability of the polypropylene material

[0009] 3. Since the interior of the car is very important in the use of the car, the car interior materials on the market have problems of poor processability, low impact resistance, insufficient surface hardness, and easy stress cracking;

[0010] 4. Since the interior of the car is exposed to the air, it needs certain antibacterial and anti-corrosion properties, flame retardant and wear resistance, and anti-oxidation and sunscreen properties. During a long period of use, there will be corrosion and peeling
