Research Progress on Blend Modification of ABS Resin

ABS resin, an acrylonitrile-butadiene-styrene copolymer, is a widely used thermoplastic material with excellent mechanical properties, processability, and electrical insulation. its inherent limitations, such as poor heat resistance and low impact strength, restrict its application under more demanding conditions. blend modification of ABS resin has become a critical approach to enhancing its comprehensive performance. This paper reviews the technical advancements in blend modification of ABS resin.

1. Principles of Blend Modification

Blend modification involves combining two or more resins or fillers with different properties to create new composite materials. For ABS resin, this process primarily aims to improve its mechanical properties, heat resistance, and chemical corrosion resistance by incorporating other resins or fillers. For example, adding thermoplastics such as polypropylene (PP) or polyethylene (PE) can enhance ABS’s heat resistance and mechanical performance, while fillers like carbon black or glass fibers can increase its tensile strength and wear resistance.

2. Blend Modification Technologies

The main techniques for modifying ABS resin include:

(1) Melt Blending Method: ABS is melted and mixed with other resins or fillers at high temperatures, followed by cooling and solidification. This method produces uniform composites but requires high equipment costs.

(2) Solution Blending Method: ABS is dissolved in an appropriate solvent, and other resins or fillers are added after dissolution. The solvent is then evaporated to obtain the composite. This approach achieves smaller dispersed phase sizes but involves complex operations.

(3) Extrusion Blending Method: ABS and other materials are blended in an extruder and shaped using molds. This technique allows for complex composite designs but has lower production efficiency.

3. Effects of Blend Modification

Blend modification significantly improves the overall performance of ABS resin. For instance:

• Adding PP enhances heat resistance and mechanical strength.
• Incorporating carbon black improves wear resistance and impact strength.
• Glass fibers increase tensile strength and rigidity. These enhancements have expanded the use of ABS resin in automotive, electronic appliances, medical devices, and other fields.

4. Challenges in Blend Modification

Despite significant progress, several challenges remain: (1) Cost Issues: The addition of other resins or fillers increases production costs. (2) Performance Balancing: Achieving a balance between mechanical properties, heat resistance, and chemical resistance remains difficult. (3) Environmental Impact: The blending process may generate hazardous substances, posing risks to the environment and human health.

5. Future Prospects

To address these challenges, future research directions include: (1) Developing low-cost blend modification technologies. (2) Optimizing processes to balance performance and cost. (3) Advancing green blending technologies to minimize environmental impact.
