Problem
Existing methods for manufacturing three-dimensional substrates with patterns face challenges such as insufficient heat resistance, adhesion issues during alkaline cleaning, and defects in black pattern printing, particularly when subjected to high temperatures and chemical strengthening processes.
Innovation Solution
A heat-resistant composition comprising a binder resin combination of silicone-modified polyester resin, siloxane, and silanol compounds, along with pigments like iron cobalt chromite black spinel and carbon black, and a low-activity catalyst, which is applied to a planar substrate before thermoforming to create a three-dimensional substrate with improved heat resistance and ease of alkaline cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heat-resistant compositions are used for printing patterns on substrates before chemical strengthening, then the patterns may provide some heat resistance, but they suffer from adhesion failure during alkaline cleaning and discoloration at high temperatures
Solution Approach 1:
The patent uses a composite binder resin system comprising silicone-modified polyester resin, siloxane compound, and silanol compound. This multi-component composite provides synergistic effects: the silicone-modified polyester offers adhesion and flexibility, the siloxane provides heat resistance and chemical stability, and the silanol enhances crosslinking density. This composite material structure resolves the contradiction by combining materials with complementary properties to achieve both high-temperature stability and adhesion resistance during alkaline cleaning.
Solution Approach 2:
The patent optimizes the weight ratios of the binder resin components (silicone-modified polyester resin: siloxane compound: silanol compound = 1:1-5:0.1-3) and pigment ratios (ICCB:carbon black = 1:1 to 9:1) to achieve the desired balance between heat resistance and adhesion. By carefully controlling these compositional parameters, the formulation maintains structural integrity at high temperatures while resisting alkaline degradation during cleaning processes.
2Temperature
If conventional pigments and binders are used for black pattern printing, then the patterns can be formed, but they exhibit insufficient heat resistance and adhesion during subsequent processing
Solution Approach 1:
The patent employs a composite pigment system combining iron cobalt chromite black spinel (ICCB) with carbon black in specific ratios (1:1 to 9:1 by weight). The ICCB provides exceptional heat resistance and color stability at high temperatures, while carbon black enhances opacity and provides a base matrix. This composite pigment formulation achieves superior heat resistance without significantly complicating the manufacturing process, as the pigments can be directly mixed into the binder resin system.
3Temperature
If the composition is designed for high heat resistance, then it can withstand high-temperature processing, but it may become difficult to clean with alkaline solutions
Solution Approach 1:
The patent converts the potential harm of strong adhesion (which would normally make cleaning difficult) into a beneficial property. The siloxane and silanol components create a crosslinked network that adheres strongly to the substrate, but this same network structure resists alkaline degradation. The strong adhesion that would normally prevent cleaning actually protects the pattern from alkaline attack, transforming the cleaning difficulty into a protective feature.
Solution Approach 2:
The patent adjusts the chemical composition parameters, specifically incorporating siloxane compounds with controlled molecular weights and silanol content, to create a network structure that is chemically resistant to alkaline solutions. The weight ratio optimization ensures the composition has sufficient crosslink density to resist alkaline degradation while maintaining the desired adhesion properties.
4Manufacturing precision
If conventional compositions are used for three-dimensional substrate manufacturing, then the process can be completed, but the patterns suffer from discoloration and adhesion loss during thermoforming and chemical strengthening
Solution Approach 1:
The patent uses a composite binder resin system with silicone-modified polyester, siloxane, and silanol that provides thermal stability throughout the manufacturing process. The siloxane and silanol components form a thermally stable crosslinked network that prevents pattern discoloration and adhesion loss during thermoforming at high temperatures and subsequent chemical strengthening processes, ensuring consistent pattern quality.
Solution Approach 2:
The patent controls the curing temperature range (190°C to 220°C for 30 minutes to 2 hours) and the compositional parameters of the binder resin to ensure the pattern maintains its integrity throughout the manufacturing process. The optimized formulation allows curing at these temperatures without causing discoloration or adhesion failure, maintaining manufacturing precision.
