Description
Technical Field
The invention relates to the technical field of plastic master batches, in particular to an antibacterial dust-adsorption-resistant composite plastic master batch and a preparation method thereof.
Background
At present, plastic products play an important role in daily life and industrial and agricultural production of people. In order to make plastic products widely used, people often add antibacterial agents into plastic master batches for preparing plastic products, so as to obtain antibacterial plastic products. Antibacterial agents used in antibacterial plastics can be classified into inorganic, organic and natural ones. The organic antibacterial agent has poor toxicological safety and poor chemical stability, and can cause the drug resistance of microorganisms; the easy migration and poor durability, especially poor heat resistance, and the antibacterial components of many antibacterial plastics are easy to decompose at high processing temperature. The natural antibacterial agent is easy to be carbonized and decomposed at high temperature, and has narrow application range and poor antibacterial effect.
Polypropylene materials are widely used in the fields of automobiles and household electrical appliances due to the characteristics of light weight, good chemical resistance, excellent heat resistance and processability, and the like. With the stricter and stricter national environmental protection requirements, ABS which can be used for electroplating or painting before is gradually replaced by spraying-free PP material due to the defects of large environmental pollution, easy rejection rate generation and the like. The spraying-free PP material is often used for preparing household appliance appearance parts due to the characteristics of good appearance effect, high glossiness and the like, but the spraying-free PP material is easy to generate the conditions of bacteria mildew, surface dust deposition and the like when being used in the environment with high humidity or more air dust, and the application range of the PP material is influenced.
Patent CN 104530565B discloses "spraying-free polypropylene composite material with antibacterial function and preparation method and application thereof", which makes PP surface spraying-free texture and antibacterial function through the action of transparent filler, antibacterial masterbatch, glass-based pearlescent pigment and other auxiliary agents. Although the spraying-free antibacterial PP material is prepared, the product does not have excellent dust adsorption resistance, and the prepared glass-based pearlescent pigment has poor metal texture and cannot completely replace spraying-free.
Therefore, the inventor provides an antibacterial dust-adsorption-resistant composite plastic master batch and a preparation method thereof in order to achieve the purpose of higher practical value, with the experience of design development and actual manufacturing which is abundant in the related industry for many years, and research and improvement are performed on the existing structure and deficiency.
