Application: We invented a new kind of three-dimensional (3-D) spacer fabric reinforcement for building thermal insulation. The reinforcement can be further filled with foamed cement to produce 3-D thermal insulation board. This new product provides the advantages of light weight, excellent mechanical performances, thermal insulation, moisture proof, low-cost, convenient construction and so on. This 3-D board can meet the requirement of flame retardant grade A, which was proved to be an ideal building thermal insulation material.
1. Innovative integrally woven network structure.
Thick spacer fabric reinforcement was produced with glass fiber. The fabric provides a low pile density. Special textile technique was developed to prevent warp and weft glass fiber yarns from sliding, and form stable fabric reinforcement.
The woven fabric with extremely low yarn density was difficult to produce. The main reason was that the weft and warp yarns crisscrossed in the woven fabric, and they were easy to slide. The woven technique decided the unstable fabric structure, especially for the fabric with low yarn density. For instance, by using the technique from patents 89103978, 200910153596, and 200580045686, the fabric with low yarn density was difficult to fabricate. The produced fabric with these patent methods deformed easily. There is no reinforcement in the thickness direction, resulting in a low mechanical performance in this direction.
2. Assembly line for foam material filling was established
This product is reinforced with glass fiber 3-D spacer fabric. The foamed cement was filled into this reinforcement. This product provides the advantages of light weight, seismic capacity, high compressive strength, innocuity, and so on. This material can meet the requirementof flame retardant grade A, and is accord with requirements of relative standard.
In addition, decorative materials can be further coated on the surface of thermal insulation board. The panel can be automatically produced and have a stable manufacturing quality. Metal, marble and granite could be used as the decorative materials. This material settled the problems of debonding, high cost, complex construction and maintenance in aluminum plate, stone material wall. This product is an ideal building thermalinsulation material.
3.Excellent mechanical performances
In the fabric reinforcement, pile yarn shuttled between top and bottom layers. The through-thickness fiber yarn improved the flatwise compression strength, flexural and tensile strength effectively. The measured flatwise compression strength and tensile strength were higher than 0.5 MPa. Also the modified foamed cement was used, which provides better thermal insulation and low water absorption rate.
This product was evaluated by National Building Materials Test Center according to GB 8624-2006. This product meets the requirement of flame retardant grade A. The performances of this product were listed in the following table.
