TECHNICAL FIELD
[0001] The present application belongs to the technical field of high polymer materials, and particularly relates to an ABS composite material, a preparation method and application thereof. BACKGROUND
[0002] With the rapid development of science and technology, ABS (acrylonitrile-butadiene-styrene copolymer) as an important thermoplastic engineering plastic has been widely used in the fields of electronic appliances, automobile manufacturing, building materials and home furnishing, etc. due to its good comprehensive mechanical properties, easy processing and excellent surface gloss. For example, in the electronic appliance industry, ABS is often used to manufacture mobile phone cases, printer parts, etc.; in the automobile field, instrument panels, door interior panels and other components also use ABS materials.
[0003] However, the requirements for material performance in modern industry are increasing, and traditional ABS materials show certain limitations in some aspects. In the field of electronic appliances, electronic products are developing towards miniaturization and integration, and the heat of internal components is concentrated, which puts higher requirements on the heat resistance of materials to avoid deformation or performance degradation due to overheating. At the same time, in order to ensure safety in use, the flame retardant performance of the material also needs to be further improved, especially in abnormal situations such as short circuit, the spread of fire needs to be effectively inhibited. In addition, the material needs to have excellent impact resistance to prevent the shell from cracking and damaging due to bumps and other situations in daily use.
[0004] In the field of automobile manufacturing, lightweight is one of the important ways to achieve energy saving and emission reduction, which requires ABS materials to reduce the density while ensuring the mechanical properties. Cars are exposed to outdoor environments for a long time and are subjected to wind, sun, rain erosion and complex conditions of high and low temperature changes, so the material must have excellent weather resistance to prevent aging, discoloration and embrittlement. At the same time, the interior parts of the car are in frequent contact with the human body, and also need to have good chemical corrosion resistance to resist the erosion of sweat, cosmetics and other chemical substances.
[0005] Currently, the common methods to improve the performance of ABS materials include adding flame retardants, reinforcing fibers, toughening agents, etc. However, these single modification methods have certain disadvantages. For example, although traditional halogen-based flame retardants can significantly improve the flame retardant effect, they may release toxic and harmful gases during combustion, posing a threat to the environment and human health; inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide, although environmentally friendly and non-toxic, can easily cause a decrease in the mechanical properties of the material when added in large amounts, and affect the processing fluidity and surface quality of the product. The addition of reinforcing fibers such as glass fibers can improve the tensile strength and bending strength of the material, but it will reduce the processing fluidity, leading to difficulty in molding, and easily causing appearance defects such as glass fiber exposure on the surface of the product. In addition, existing modification methods often have difficulty in balancing other properties when improving a certain property, resulting in poor overall performance of the material and difficulty in meeting the diverse needs of various fields. Therefore, developing an ABS composite material with synergistic improvement of various properties through reasonable formulation design and innovative preparation process has become a technical problem to be solved in the field.
