Description
Technical Field
The invention belongs to the technical field of modified plastics, and particularly relates to an acrylonitrile-styrene-butadiene copolymer composite material, and a preparation method and application thereof.
Background
Acrylonitrile-styrene-butadiene copolymer (ABS resin) is widely used in household appliances, electronics and electricity, medical treatment, energy, office supplies, transportation and other fields. The security door base for supermarkets is mainly made of BMC materials, has the characteristics of flame retardance, high rigidity and the like, and has the defects of poor processability, incapability of recycling and the like. Therefore, the adoption of high-strength and high-rigidity flame-retardant reinforced ABS material to replace BMC material is the current trend. The natural color of the ABS resin has the characteristics of high gloss, good toughness and solvent resistance, but the ABS resin also has the defects of poor weather resistance, poor boiling resistance of the reinforcing material and the like.
For example, CN109851978a discloses a modified ABS resin comprising the following components in mass fraction: 100-110 parts of ABS resin, 8-10 parts of titanium dioxide, 20-30 parts of polycarbonate, 10-15 parts of polypropylene, 0.4-1 part of vinyl bis-stearamide, 0.1-0.5 part of phosphite ester and 0.1-0.5 part of calcium stearate. However, the flexural modulus of the resin is required to be further improved, and the boiling resistance is poor.
In addition, by combining simulation data, the flexural modulus of the material of the security door base for supermarkets needs to be more than 8000MPa, and in addition, the material is a long-term use part and needs to have good weather resistance. However, the common defects of the prior art are that the performance of the conventional flame-retardant reinforced ABS is greatly reduced after boiling, the color difference is large after aging, and the flexural modulus of the conventional glass fiber reinforced flame-retardant ABS material is low.
Therefore, the development of the ABS composite material with high rigidity, boiling resistance, good weather resistance and good flame retardance is a technical problem to be solved in the field.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention aims to provide an acrylonitrile-styrene-butadiene copolymer composite material, and a preparation method and application thereof. The acrylonitrile-styrene-butadiene copolymer composite material has high rigidity and excellent boiling resistance and weather resistance, and solves the problems of boiling resistance deviation, weather resistance deviation, low rigidity and the like commonly existing in security door materials in the prior art.
To achieve the purpose, the invention adopts the following technical scheme:
