Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional semi-solid muddy gels have poor viscosity, rebound rate, and lack tensile strength, limiting their application.
Innovation Solution
A viscoelastic mud is prepared using 4% to 20% elastomer, 0% to 40% softening oil, and 40% to 96% liquid rubber, with the elastomer being styrenic block copolymer or semi-solid polyisobutylene rubber, mixed and melted at 120° C to 220° C to achieve suitable viscosity, rebound rate, and tensile strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional semi-solid muddy gels (plasticine, wax mud, mineral mud) are used, then the material is easy to manufacture, but the viscosity, rebound rate, and tensile strength are poor
Solution Approach 1:
The patent uses composite materials by combining elastomer particles (styrenic block copolymer or semi-solid polyisobutylene rubber) with liquid rubber and softening oil to create a viscoelastic mud that achieves both high tensile strength and ease of manufacture. The specific composition (4-20% elastomer, 0-40% softening oil, 40-96% liquid rubber) creates a material that is both strong and manufacturable.
Solution Approach 2:
The patent applies parameter changes by controlling the temperature during mixing and melting processes. The mixture is heated to 120-220°C to melt the elastomer particles and achieve proper viscosity and tensile strength, then cooled to room temperature for final product formation. This temperature parameter control resolves the contradiction between strength and manufacturability.
2Speed
If conventional semi-solid muddy gels are used, then the material is simple in composition, but the rebound rate is poor
Solution Approach 1:
The patent employs composite materials consisting of elastomer particles dispersed in liquid rubber with softening oil. This composite structure provides the viscoelastic properties necessary for high rebound rate while maintaining a relatively simple three-component composition that is not overly complex to prepare.
Solution Approach 2:
The patent uses parameter changes in the form of temperature control (120-220°C heating followed by cooling to room temperature) to achieve the desired rebound rate. The thermal processing transforms the composition into a viscoelastic material with optimal elastic recovery properties without requiring complex compositional modifications.
3Force
If conventional semi-solid muddy gels are used, then the formulation is simple, but the viscosity is poor
Solution Approach 1:
The patent applies parameter changes through temperature control during processing. Heating the mixture to 120-220°C melts the elastomer particles and adjusts the viscosity to appropriate levels, while cooling to room temperature finalizes the viscosity characteristics. This thermal parameter control achieves desired viscosity without complex formulation adjustments.
Solution Approach 2:
The patent uses composite materials with specific proportions (4-20% elastomer, 0-40% softening oil, 40-96% liquid rubber) to achieve optimal viscosity. The combination of these materials creates a viscoelastic fluid with appropriate resistance to flow while maintaining a relatively simple three-component formulation.
