Abstract
Official abstract text for this publication.
A fireproof cladding material for covering or coating a plastic pipeline, includes a cross-sectional structure formed by needle punch or thermal bond to form a two-layer or three-layer laminated structure with an integrated structure. The laminated structure of the cross-sectional structure is composed of a fireproof fiber woven blanket having a thickness of 0.2-250 mm, and an upper side or a lower side of the fireproof fiber woven blanket, or both sides of the upper side and the lower side thereof, is composed of a fireproof reinforcement layer with a thickness of 0.015-0.5 mm. The fireproof cladding material has the characteristics of softness, bendability, light weight and high strength, and is suitable for covering or coating plastic pipelines.
First claim
Opening claim text (preview).
What is claimed is: 1. A fireproof cladding material for covering or coating a plastic pipeline, including a cross-sectional structure formed by needle punch or thermal bond to form a two-layer or three-layer laminated structure with an integrated structure, wherein the laminated structure of the cross-sectional structure is composed of a fireproof fiber woven blanket having a thickness of 0.2-2 mm, and an upper side or a lower side of the fireproof fiber woven blanket, or both sides of the upper side and the lower side thereof, is composed of a fireproof reinforcement layer having a thickness of 0.015-0.2 mm; wherein the fireproof fiber woven blanket is selected from a PAN oxidized fiber woven carpet and a water-soluble alkaline earth fiber woven blanket, and the fireproof reinforcement layer is selected from a glass fiber cloth, a carbon fiber cloth and a silicone rubber. 2. The fireproof cladding material according to claim 1 , wherein the fireproof reinforcement layer is a glass fiber cloth or a carbon fiber cloth having a warp and weft density of 55×53 to 10×10. 3. The fireproof cladding material according to claim 1 , wherein the fireproof reinforcement layer is a glass fiber cloth or a carbon fiber cloth having a warp and weft density of 20×18 to 17×17. 4. The fireproof cladding material according to claim 1 , wherein a lower side of the fireproof fiber woven blanket is laminated with a flame-retardant double sided adhesive tape.
