Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin products often accumulate electrostatic charges during manufacturing or application, leading to issues such as dust adsorption, electric shock, and fire or explosion hazards, necessitating a resin composition that effectively prevents electrostatic charge accumulation.
Innovation Solution
A resin composition comprising a resin carrier, conductive carbon black, and graphene, with specific weight percentages, is formulated by mixing a graphite material with an intercalating agent, obtaining a graphene solution, drying it to powder form, and combining it with conductive carbon black and resin carrier to achieve uniform dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional resin materials are used, then the resin provides good insulating properties and mechanical strength, but the resin accumulates electrostatic charges during manufacturing or application
Solution Approach 1:
The patent creates a composite resin material by combining conventional resin with conductive carbon black particles and graphene. This composite structure provides both the mechanical strength and insulating properties of the base resin while the conductive additives (carbon black and graphene) form a dispersed conductive network that enables electrostatic charge dissipation, directly resolving the contradiction between insulating performance and electrostatic charge accumulation.
Solution Approach 2:
The patent modifies the electrical conductivity parameter of the resin by incorporating specific amounts of conductive carbon black (1-3 wt%) and graphene (2-4 wt%). This parameter change transforms the resin from an insulating material that accumulates charges to a material with controlled conductivity that can dissipate electrostatic charges, while maintaining the resin's mechanical properties through optimized composition ratios.
2Reliability
If conductive additives are added to resin to reduce electrostatic charges, then electrostatic dissipation improves, but the uniformity of dispersion and mechanical properties may deteriorate
Solution Approach 1:
The patent merges two different conductive additives (carbon black and graphene) into the resin matrix. This combination is strategic because carbon black provides bulk conductivity while graphene, with its two-dimensional structure and high aspect ratio, creates efficient conductive pathways at lower concentrations. The synergistic effect of combining these two additives achieves uniform dispersion and effective electrostatic dissipation without compromising mechanical properties, as each additive complements the other's strengths.
