Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The redispersibility of metal compound particles in liquid compositions is insufficient, leading to inhomogeneous compositions and stability issues during storage, even with surface coating or dispersant addition.
Innovation Solution
A liquid composition comprising C5-10 alkyl tri-C1-3 alkoxysilane-treated zinc oxide particles with specific properties is used to enhance the redispersibility of metal compound particles, including zinc oxide, barium sulfate, and titanium mica, by improving their dispersion and preventing agglomeration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If surface coating or dispersant addition is used to maintain dispersibility, then the formation of aggregates is suppressed, but the redispersibility remains insufficient and significant stirring effort is required
Solution Approach 1:
The patent introduces a specific intermediary substance - C5-10 alkyl tri-C1-3 alkoxysilane-treated zinc oxide particles - that mediates between the metal compound particles and the liquid composition. This treated zinc oxide acts as a redispersion facilitator, enabling easy redispersion of aggregated particles without requiring significant stirring effort, thus resolving the contradiction between maintaining dispersibility and achieving ease of redispersion
Solution Approach 2:
The patent changes the surface properties of zinc oxide particles through chemical treatment with C5-10 alkyl tri-C1-3 alkoxysilane. This parameter change in surface chemistry transforms the zinc oxide into an effective redispersion facilitator that can easily separate and redisperse metal compound particles, solving the redispersibility issue while maintaining composition stability
2Adaptability or versatility
If metal compound particles with large specific gravity and large particle size are used, then various functions can be obtained, but they precipitate and form agglomerates in liquid composition
Solution Approach 1:
The C5-10 alkyl tri-C1-3 alkoxysilane-treated zinc oxide particles serve as an intermediary that interacts with heavy metal compound particles, preventing their precipitation and agglomeration while maintaining their functional properties. This mediator enables the coexistence of particles with large specific gravity and large particle size in the liquid composition without loss of stability
Solution Approach 2:
The patent creates a composite system combining metal compound particles with C5-10 alkyl tri-C1-3 alkoxysilane-treated zinc oxide particles. This composite structure allows the heavy metal particles to maintain their functional characteristics while the treated zinc oxide provides stabilization, preventing aggregation and maintaining composition stability throughout the liquid formulation
3Duration of action of stationary object
If liquid composition is used for a long time without sufficient redispersion, then storage stability is compromised, but component composition becomes inhomogeneous
Solution Approach 1:
The C5-10 alkyl tri-C1-3 alkoxysilane-treated zinc oxide particles perform preliminary action by continuously maintaining a dispersed state of metal compound particles throughout the liquid composition. This preliminary dispersion action prevents aggregation from occurring in the first place, ensuring both storage stability and compositional homogeneity even after prolonged storage without requiring additional redispersion efforts
