Engineering Contradiction Analysis
1Object-affected harmful factors
If polyalkylene carbonate resin alone is used for wallpaper production, then environment-friendliness is improved, but shape retention at room temperature deteriorates
Solution Approach 1:
The patent uses a composite material system consisting of polyalkylene carbonate resin as the base polymer combined with specific additives including crosslinking agents (silane compounds), chain extenders (carboxylic acid compounds), and plasticizers. This composite approach allows the material to maintain the environmental benefits of polyalkylene carbonate while gaining improved shape retention and dimensional stability through the synergistic effects of the additives.
Solution Approach 2:
The patent changes the chemical and physical parameters of the polyalkylene carbonate resin by controlling the molecular weight (10,000 to 1,000,000), incorporating specific ratios of crosslinking agents (0.1-10 parts by weight per 100 parts resin) and chain extenders (0.1-10 parts by weight per 100 parts resin). These parameter adjustments enable the resin to achieve both environmental friendliness and adequate shape retention performance.
2Ease of manufacture
If PVC resin is used for decorating materials, then processability is improved, but harmful gas generation during burning increases
Solution Approach 1:
The patent converts the potential harm of using conventional PVC by replacing it with polyalkylene carbonate resin, which is derived from renewable resources and produces minimal harmful emissions when burned. The resin maintains adequate processability through the addition of plasticizers and processing aids, thereby converting an environmentally harmful material into an eco-friendly alternative without sacrificing manufacturing ease.
Solution Approach 2:
The patent changes the base material from PVC to polyalkylene carbonate resin and adjusts the compositional parameters by incorporating specific amounts of plasticizers (5-50 parts by weight per 100 parts resin) and processing aids (0.1-5 parts by weight per 100 parts resin). These parameter changes ensure that the new material achieves processability comparable to PVC while eliminating the harmful gas generation issue.
3Shape
If polyalkylene carbonate resin composition is optimized for shape retention, then dimensional stability at high temperature is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by incorporating crosslinking agents and chain extenders during the resin composition formulation stage, which pre-establish the molecular network structure necessary for high-temperature dimensional stability. The silane crosslinking agents form three-dimensional networks that lock the molecular structure, while chain extenders increase molecular weight and reduce chain mobility. This preliminary structuring ensures shape retention is built into the material itself, reducing the need for complex post-processing controls.
Solution Approach 2:
The patent uses silane crosslinking agents as intermediaries that bridge polymer chains to form a three-dimensional network structure. These crosslinking agents act as mediators between the polyalkylene carbonate resin molecules, creating strong intermolecular bonds that provide dimensional stability at high temperatures without requiring complex manufacturing processes. The crosslinking reaction occurs during processing, automatically establishing the stable structure.
