Flocking-imitating polypropylene composite material as well as preparation method and application thereof

Abstract

The invention discloses a flocked polypropylene composite material as well as a preparation method and application thereof. The flocked polypropylene composite material comprises the following raw materials in parts by weight: 40-70 parts of polypropylene, 5-20 parts of an elastomer, 5-25 parts of glass fibers, 0.2-5 parts of polyester fibers, 1-10 parts of negative ion powder, 0.5-5 parts of a compatilizer, 0.1-0.5 part of a lubricant, 0.2-1 part of an antioxidant and 0.1-0.5 part of a weather-resistant agent. According to the invention, the high-share small-particle-size elastomer and polyester fiber are added into the light-color polypropylene material, so that the visual and soft touch effect similar to imitation flocking is achieved, and the plastic feeling and glossiness of the material are greatly reduced. In addition, due to the introduction of efficiently released negative ion powder, the product can release a large number of small-particle-size negative ions for a long time, has the effects of resisting and inhibiting bacteria, removing odor and dust, degrading harmful VOC in the environment in an automobile and the like, and has a wide application prospect in automotive interior products.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a flocking-like polypropylene composite material and a preparation method and application thereof. Background technique [0002] Polypropylene material is widely used in automotive interior and exterior trim products because of its excellent mechanical properties, chemical resistance, recyclability, etc., as well as good processing performance, plasticity and design. The widest range of general-purpose plastics. However, polypropylene material has a high gloss, and when applied to interior products such as pillars and door panels, it feels like hard plastic, which affects consumers' visual and tactile experience. Generally, in order to improve the visual and tactile quality of the interior, textile fabrics are often used for covering, which not only complicates the process and increases the cost, but also causes disadvantages such as odor and VOC increase in the car ...

However, polypropylene material has high gloss, and it is obviously hard plastic when applied to interior products such as pillars and door panels, which affects consumers' visual and tactile experience

Generally, in order to improve the visual and tactile quality of the interior, textile fabrics are often used for covering, which not only complicates the process and increases the cost, but also causes disadvantages such as odor and VOC increase in the car interior due to the adhesive used for covering.

[0003] In order to further cater to consumers' preferences, according to the current trend of automotive interior materials, major OEMs focus on how to reduce the hard plastic feel and surface gloss of automotive interior materials, so that the surface of the material shows a certain degree of matte and The bionic effect can improve the quality of automotive interior materials and meet customer needs, but most of the existing flocking materials only focus on achieving the visual effect similar to flocking materials, but the tactile sense is poor, and there are common problems of hard plastics
