Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If organophosphorus flame retardants are used in fireproof coatings, then flame retardancy is improved, but compatibility and mixing uniformity with aqueous latex deteriorates
Solution Approach 1:
The patent modifies the molecular structure of organophosphorus flame retardants by introducing specific functional groups (hydroxyl, carboxyl, or amine groups) to change their chemical parameters, thereby improving compatibility with aqueous latex while maintaining flame retardancy
Solution Approach 2:
The patent creates composite flame retardant molecules that combine organophosphorus compounds with water-soluble functional groups, forming a hybrid structure that integrates both flame retardant properties and water compatibility
2Ease of manufacture
If flame retardants are mixed with aqueous latex by physical blending, then ease of manufacture is improved, but flame retardant performance deteriorates due to insufficient H and O elements
Solution Approach 1:
The flame retardant molecules are designed to self-provide the necessary H and O elements through their own molecular structure (containing hydroxyl, carboxyl, or amine groups), eliminating the need to rely on external water sources and ensuring sufficient elements for carbonized layer formation
Solution Approach 2:
The flame retardant is pre-equipped with H and O-containing functional groups before mixing, so that when heating occurs, the necessary elements for dehydration and carbonized layer formation are already available in the flame retardant structure itself
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The coating material achieves uniform dispersion and stable adhesion, forming a carbonized layer to prevent combustion, with improved flame retardancy and reduced risk of delamination.
Implementation Method 1
the C—P bond breaks first during heating, thereby leading to a decrease in the thermal decomposition temperature... a C—P bond contained in the flame retardant can absorb heat and play a flame retardant effect
Implementation Method 2
metaphosphoric acid covers the surface of the burning polymer in a glass film to isolate oxygen, preventing combustion
Implementation Method 3
when the flame retardant is mixed with an aqueous latex, the compatibility and mixing uniformity of the flame retardant with the latex can be improved by hydrogen bonding, thus enabling uniform dispersion in the fireproof coating material
Implementation Method 4
facilitating dehydration of the polymer to form a carbonized layer, thereby preventing or reducing the production of combustible gas... the hydroxyl can provide H and O elements for a dehydrating carbonization step in a flame retardant mechanism, thereby forming a carbonized layer to isolate oxygen

AI summary
The present application discloses a fireproof coating material, and belongs to the technical field of fireproof coatings. The fireproof coating material includes 40-80 parts of an aqueous curing agent, 20-50 parts of water and 80-200 parts of a mother liquor of the fireproof coating material, wherein the mother liquor of the fireproof coating material consists of 50-80 parts of a flame retardant, 15-25 parts of a dispersant and 190-220 parts of water. The flame retardant used can not only effectively improve the problems of poor compatibility and mixing uniformity of a flame retardant with an aqueous latex in the existing fireproof coating material, but also can utilize O and H contained in a flame retardant system to form a carbonized layer during dehydration to isolate oxygen, preventing combustion, and enhancing the fire retardant performance.
