Description
Technical field
The utility model relates to film material for construction field, strengthens membrane structure in especially a kind of glass fibre.
Background technology
Membrane structure refers to utilizes film material energetically, and in structure and architectural design, fully demonstrates the version of membrane structure feature.Membrane structure originate in ancient times nomadic people with animal skin push up, branch makees the tent that post is built, since entering modern society, people utilize similar principle, make provisional facility, as the camp tent etc. of use of march.Roofing at that time has only been done the fabric of simple water-proofing treatment for some, be all difficult to reach the requirement of permanent structure at aspects such as intensity, stability and durability.Modern Membrane Structure is be used widely and develop along with succeeding in developing of architectural fabrics composite.High-strength, the soft Fabric composites of the general employing of membrane structure material.Film material is as construction material, requires to possess the physical properties such as good fire-resistant, durability and waterproof, self-cleaning and mechanical property preferably.The mechanical characteristic of film material mainly determines by inner base fabrics, and physical characteristic is mainly determined by external skin.The film material that membrane structure industry is comparatively extensively approved both at home and abroad is at present divided into A, B, C third-class structure film material.Category-A is for take glass fabric as base material coating polytetrafluoroethylene (PTFE) (being called for short PTFE) emulsion, and form through the above high temperature sintering of 350 degree, because glass fabric and PTFE have noninflammability, so this film material has highly effective flame-retardant, but its processing difficulties expensive; Category-B is to take glass fabric as base material coating polyvinyl chloride (being called for short PVC) coating, this film material is base material because adopting glass fabric, and its flame retardant effect significantly improves, but the associativity of glass fibre and PVC is poor, in use easily decortication, has therefore limited its extensive use; C class is to take dacron fabric as base material, applies PVC coating, because dacron fabric very easily burns, makes the flame retardant effect of polyester PVC film material undesirable, in the process of using, is prone to potential safety hazard.
Summary of the invention
The purpose of this utility model is the technical problem existing in existing membrane structure, has proposed a kind of glass fabric and reinforced polyvinyl chloride structure of composite membrane in glass fibre that PVC film close is combined.
The technical scheme that the utility model adopts is: reinforced polyvinyl chloride structure of composite membrane in a kind of glass fibre, it is layer structure, be to using glass fabric as the intermediate layer 1 of interior enhancing, through the coated tack coat 2 of the PVC of immersion coating pasty state from inside to outside successively, apply density 80-100 g/m
2; Apply density 400-450 g/m
2reverse side calendering PVC film 3; Apply density 400-450 g/m
2front calendering PVC film 4; Apply density 4-6 g/m
2front surface coated PVDF Surface Treated Films 5.
Above-mentioned intermediate layer 1 is that woven density warp-wise 9-12 root/cm broadwise is 9-12 root/cm; Filament diameter is 4-6 μ m glass fabric.
Process through having double-basis group silane finish in above-mentioned intermediate layer 1, in the middle of its surface and the coated tack coat 2 of PVC, forms chemical bond.
The coated tack coat 2 of above-mentioned coating paste PVC adopts the mode of immersion coating, and baking oven pregel is processed.This tack coat 2 infiltrates through in the braiding hole of glass fabric.
Above-mentioned positive and negative coating PVC film 3, PVC film 4 adopt hot melt calendering coating method, and directly cooling and shaping is processed.
The coated tack coat 2 of above-mentioned coating paste PVC, reverse side calendering PVC film 3, positive calendering PVC film 4, fuse into one by high-temperature heating, improved the peel strength of membrane structure material.
Above-mentioned front surface coated PVDF Surface Treated Films 5 adopts gravure roll to apply, through oven drying film forming.
The coated tack coat 2 of paste PVC of above-mentioned coating, reverse side calendering PVC film 3, positive calendering PVC film 4, all add flame retardant effect auxiliary material.
Effect of the present utility model: 1. the utility model adopts through double-basis group silane finish and processes glass fabric base cloth as the intermediate layer 1 of interior enhancing, silane finish is at the middle chemical bond that forms of the coated tack coat 2 of glass fabric and the paste PVC with flame retardant effect simultaneously, and in coating procedure, reverse side calendered film 3, positive calendering PVC film 4 effectively fuse into one by high temperature, have strengthened the peel strength of product.2. adopt glass fabric base cloth as the intermediate layer 1 of interior enhancing, the characteristic that it does not fire, has strengthened the flame retardant effect of product.After tested, membrane structure product peel strength of the present utility model reaches 130N/5cm and fire-retardant rank reaches B1 level.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure: 1-intermediate layer, 2-apply paste PVC tack coat, 3-reverse side calendering PVC film, 4-positive calendering PVC film, 5-front surface coated PVDF Surface Treated Films.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described:
Embodiment 1
As shown in Figure 1, intermediate layer 1 filament diameter is 4.5 μ m; Woven density is that 12/inch of warp-wise broadwise is 12/inch; Front surface coated paste PVC packed layer 2 is applied to 80 g/m
2; Reverse side calendering PVC film 3 is applied to 420 g/m
2; Positive calendering PVC film 4 is applied to 450 g/m
2; Front surface coated PVDF Surface Treated Films 5 is applied to 6 g/m
2; Each layer is composited through hot melt calendering.Intermediate layer 1, front surface coated paste PVC packed layer 2, reverse side calendering PVC film 3, positive calendering PVC film 4 is composited through hot melt calendering.Front surface coated PVDF Surface Treated Films 5 applies through gravure roll, oven for drying, and setting roll is composited.
