Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional polymer concrete systems are toxic, have limited temperature resistance, and are not fireproof, making them unsuitable for certain applications, while plant-based alternatives offer lower strength and complex mixing requirements, and existing insulation methods lack comprehensive solutions for high-strength, cost-effective, and environmentally friendly building materials.
Innovation Solution
A building material comprising a binder (cement) and dispersion adhesive, which hardens without additional water, creating a high-strength, fireproof, waterproof, and non-toxic concrete variant that combines the properties of cement and polymer concretes, using additives like sand and glass fibers for reinforcement, and incorporating a cavity with negative pressure for enhanced insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polymer concrete systems based on mineral oil-based resins are used, then waterproof properties are achieved, but temperature resistance is limited and fire resistance is absent
Solution Approach 1:
The patent creates a composite material system combining cement-based binder with dispersion adhesive containing polymer particles. This composite structure integrates the waterproof properties of polymer systems with the high-temperature stability of cement, achieving both water resistance and improved temperature resistance up to 100°C while maintaining fire safety characteristics.
2Object-affected harmful factors
If plant-based epoxide resins are used, then toxicity is reduced, but strength and reaction rate are lower
Solution Approach 1:
The patent modifies the polymer particle characteristics by controlling diameter (0.01-1 mm), density (0.8-2.5 g/cm³), and composition ratios. These parameter optimizations enhance the bonding strength and reaction rate of plant-based epoxide resins while maintaining their non-toxic properties, achieving both low toxicity and high strength requirements.
3Manufacturing precision
If precise mixing ratios are maintained for plant-based epoxies, then reaction quality is improved, but application complexity increases
Solution Approach 1:
The dispersion adhesive formulation enables self-regulating mixing through its unique composition and particle distribution. The system automatically achieves proper mixing ratios and reaction conditions without requiring complex measurement and control procedures, simplifying application while maintaining high reaction quality.
4Temperature
If cement-based binder is used, then fire resistance and strength are improved, but waterproofing and bonding action are reduced
Solution Approach 1:
The patent develops a composite system where cement-based binder provides fire resistance and structural strength, while dispersion adhesive with polymer particles provides waterproofing and bonding capabilities. The synergistic combination achieves all required properties simultaneously, with the polymer particles filling cement pores and creating a water-resistant matrix.
5Strength
If steel reinforcement is added to conventional concrete, then strength is improved, but cost and complexity increase
Solution Approach 1:
The patent optimizes the dispersion adhesive composition and particle distribution to achieve enhanced bonding strength without steel reinforcement. By controlling polymer particle characteristics and adhesive formulation, the material achieves flexural strengths exceeding 10 Nm/mm² through pure bonding action, eliminating the need for steel reinforcement and simplifying construction.

AI summary
To design a building block with a fully enclosed cavity, defining an internal volume, in a cost-effective manner while simultaneously achieving enhanced insulation performance, it is proposed that the cavity of the block be kept under negative pressure relative to the ambient environment under normal conditions. The building block is manufactured from a two-component polymer material based on a native epoxy resin, such as a vegetable oil, which is mixed with a building material mixture containing fillers and a hardener—in the form of a combination of polycarboxylic acid, particularly maleic acid, and hydroxycarboxylic acid, particularly citric acid—and then reacted.
