Abstract

The invention discloses a special automobile exterior trim part material added with a waste mask melt-blown material. The special automobile exterior trim part material is prepared from the followingraw materials in parts by weight: 80-100 parts of PC resin, 50-60 parts of waste mask reclaimed material, 10-20 parts of flame-retardant filler, 10-15 parts of modified montmorillonite, 5-10 parts ofbasalt fiber, 1-5 parts of flexibilizer, 1-3 parts of light stabilizer and 1-3 parts of coupling agent. The flame-retardant filler is added to endow the composite material with excellent flame retardancy and heat resistance, the modified montmorillonite and the flexibilizer endow the composite material with excellent toughness and impact resistance in inorganic and organic aspects, and the titanium dioxide can scatter and absorb ultraviolet rays, thereby enhancing the aging resistance of the composite material. The melt-blown material in waste masks is utilized to implement secondary high-efficiency utilization of the waste and reduce pollution, so that the special material for the automobile exterior trim part has the characteristics of impact resistance, high-temperature resistance, flame retardancy, low cost, environment friendliness, health and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of automobile exterior decorations, and in particular relates to a special material for automobile exterior decorations added with waste mask melt-blown materials. Background technique [0002] Most of the large-scale outbreaks in recent years are respiratory infectious diseases, such as COVID-19, SARS, highly pathogenic avian influenza, H1N1 influenza, etc. Respiratory infectious diseases are transmitted through droplets and air, with fast transmission speed and high susceptibility. The characteristics of large crowds and high morbidity pose a great threat to public health and social stability. Wearing a mask can block the invasion of pathogenic microorganisms into the human body, and is an effective means to prevent the epidemic of respiratory infectious diseases and protect the health of personnel. [0003] At present, conventional protective masks mostly use polypropylene melt-blown nonwov...
