Resin-Coated Glass Fiber Weave for Translucent Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin-coated flame-retardant glass fiber woven fabrics face challenges in achieving both sufficient thermal insulation and translucency due to the low thermal insulation performance of pigments and deteriorated air permeability from resin coatings, which also limits design variability and practicality in applications like blinds.
Innovation Solution
A resin-coated flame-retardant glass fiber bundle with a first resin coating layer and a second resin coating layer, where the second layer contains titanium dioxide particles in a specific mass ratio of 4-12% and particle size distribution (0.6-1.5 µm and 0.2-0.4 µm) to enhance thermal insulation and translucency, while maintaining good weaving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a resin coating layer containing pigment is formed on the glass fiber bundle, then the woven fabric has translucency, but the thermal insulation performance deteriorates
Solution Approach 1:
The invention changes the particle size parameter of titanium dioxide from conventional single-size to a specific dual-size distribution (first particles: 0.6-1.5 µm, second particles: 0.2-0.4 µm). This parameter change enables the coating to achieve both translucency (through appropriate light scattering) and thermal insulation (through infrared reflection), resolving the contradiction between these two properties.
Solution Approach 2:
The invention creates a composite resin coating layer containing both first and second titanium dioxide particles with different size ranges. This composite structure allows the coating to simultaneously provide translucency (via the first particles) and thermal insulation (via the second particles), overcoming the limitation of using single-size particles or conventional pigments.
2Reliability
If the glass fiber bundle is coated with resin to improve flame retardancy and durability, then the weaving performance deteriorates
Solution Approach 1:
The invention applies local quality by creating a resin coating layer with specifically controlled titanium dioxide particle distribution. The coating provides flame retardancy and durability where needed while maintaining sufficient flexibility and smoothness in the coating structure to allow proper weaving performance, thus resolving the contradiction between reliability and ease of manufacture.
3Illumination intensity
If conventional pigments are used in the resin coating, then the translucency is maintained, but the thermal insulation performance is insufficient
Solution Approach 1:
The invention replaces conventional pigments with titanium dioxide particles of specific size ranges. This parameter change in particle size enables the material to provide both translucency (through controlled light scattering) and superior thermal insulation (through infrared reflection), directly resolving the insufficiency of conventional pigments in providing thermal insulation.
Solution Approach 2:
The invention uses a composite structure of two different titanium dioxide particle sizes instead of conventional single-type pigments. This composite approach allows the coating to achieve both translucency and thermal insulation properties that conventional pigments cannot provide alone.
