Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-sticking agents for unvulcanized rubber often fail to balance effective anti-sticking properties with removability from equipment surfaces, leading to contamination issues due to poor adhesion and removal characteristics.
Innovation Solution
An anti-sticking agent composition comprising a water-soluble polymer, metallic soap, and surfactant, specifically including non-ionic cellulose ether, which forms a film that enhances adhesion and removability while maintaining lubricating ability and dispersibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a water-soluble polymer is blended to increase viscosity of the aqueous dispersion liquid, then adherability to rubber surface is improved, but removability from equipment surface deteriorates
Solution Approach 1:
The invention changes the chemical composition parameters of the water-soluble polymer from conventional types (sodium alginate, CMC, sodium polyacrylate, PVA) to a specific polymer with controlled molecular weight and chemical structure. This parameter change allows the polymer to provide sufficient adhesion during processing while enabling easy removal from equipment surfaces, resolving the contradiction between adherability and removability
Solution Approach 2:
The invention creates a composite anti-sticking agent system combining a specifically selected water-soluble polymer with inorganic powder particles. The polymer forms a matrix that binds the inorganic particles while providing controlled adhesion characteristics. This composite structure enables both good adherability to rubber and ease of removal from equipment, as the polymer-inorganic particle composite can be applied effectively and then removed cleanly
2Reliability
If inorganic powder is used as main component, then anti-sticking properties are achieved, but dust generation occurs
Solution Approach 1:
The water-soluble polymer forms a flexible film or coating that encapsulates the inorganic powder particles. This thin polymer film acts as a binding matrix that holds the inorganic particles together, preventing them from breaking loose as dust during handling and application. The inorganic powder provides anti-sticking properties while the polymer film prevents dust generation
Solution Approach 2:
The invention creates a composite material where inorganic powder particles are dispersed and bound within a water-soluble polymer matrix. The inorganic component provides the anti-sticking function while the polymer component provides structural integrity and dust control. This composite structure allows both anti-sticking properties and dust reduction to be achieved simultaneously
