Abstract

The invention discloses an automobile interior material being suitable for vacuum molding and achieving pearlescent appearance. The automobile interior material comprises a TPO surface and waterborne paint which is uniformly applied to the TPO surface, and the waterborne paint is waterborne polyurethane paint which is prepared from 60-75 parts of waterborne polyurethane dispersoid, 0.5-1.5 parts of a polyurethane thickening agent, 0.1-0.5 part of an isocyanate curing agent, 30-60 parts of water and 0.5-2 parts of silicon dioxide. According to the automobile interior material, the metal effect of TPO is enhanced, the metal-color appearance is given to the TPO surface, and then the automobile interior material achieves the unique effect different from the effect generated when dye is used in the past; brand new visual enjoyment is provided for a user, the interior material with the metal pearlescent appearance gives the high-end feeling to the user, the status symbol of the user is improved, and the requirement of existing automobile interior material development is met.

Description

technical field [0001] The invention relates to the field of automotive interior materials, in particular to an automotive interior material with a pearlescent appearance that is suitable for vacuum forming. Background technique [0002] Polyolefin thermoplastic elastomer (TPO) has been widely used in automotive interior materials in recent years. Compared with PVC materials, it has lower VOC emission, firm pattern retention, and good scratch resistance. Polyolefin The appearance method of thermoplastic elastomer (TPO) usually achieves the purpose of adjusting the color of TPO skin by adding different dyes in the extrusion stage. Since the color is adjusted by heating and rolling the dye in the extrusion stage, it is very difficult to make a colorful skin. As automotive customers have higher and higher requirements for the appearance of interior materials, if they want a metallic effect, they cannot be obtained by traditional extrusion methods. Moreover, traditional TPO ha...
