Abstract
The utility model discloses a polytetrafluoroethylene film material composed of three layers. The middle layer is a fiberglass cloth layer. The upper layer is a mixed layer, so is the lower layer. The mixed layer is made of polytetrafluoroethylene, inorganic filling material and compatilizer which are mixed. The film material of the utility model is a fire-new building structural style. The utility model synthetizes architecture, mechanics of structure, fineness chemical industry and materials, computer art, etc. The utility model has higher technique content, higher tensile strength, excellent resistance to aging, large visible space, good fireproofness and self-cleaning. The life time of the film material is prolonged. The film material of the utility model can be widely applied to ceilings of various sport devices, large-scale gyms and public buildings.
Description
Technical field: the utility model belongs to environmental protection technical field, relates to a kind of polytetrafluoroethylene (PTFE) film material.
Background technology: ancient architectural mode mainly adopts building steel mixed structure, last century the fifties, the membrane structure building begins to occur in the world as the construction style that breaks fresh ground, history about 50 years is arranged so far, particularly to after the last century the eighties, the application of membrane structure has obtained developing rapidly.Use at present the film material mostly exist tensile strength low, shortcoming such as not ageing-resistant, visible space is few, and service life is short.
Summary of the invention: the purpose of this utility model provide a kind of tensile strength height, ageing-resistant, use the poly tetrafluoroethylene material receive a mandate long.
The utility model poly tetrafluoroethylene material is formed by three layers, and the centre is the glass fibre layer of cloth, and upper and lower layer is a mixed layer; Mixed layer is made of polytetrafluoroethylene (PTFE), inorganic filling material and compatilizer mixing.
Said upper and lower layer mixed layer thickness is respectively 0.2mm, and the thickness of glass fibre layer of cloth is 0.45mm.
Mixed layer of the present utility model is according to different structural requirements, and the proportioning of ptfe emulsion, inorganic filling material and compatilizer was generally 100: 10: 0.4.Inorganic filling material is silica, common salt etc.
The manufacturing principle of utility model: under 270 ℃ ± 5 ℃ temperature control, the dipping surface conditioning agent, the ptfe emulsion of continuous impregnating 45% concentration under the control of 370 ℃ ± 5 ℃ temperature then, the ptfe emulsion of 45% concentration is formed by pure ptfe emulsion dilution, make the polytetrafluoroethylene (PTFE) molecule fill up the space of glass fabric, purpose is the tensile strength of cloth of reinforcement fibers, the mixed liquor of dipping polytetrafluoroethylene (PTFE) carries out sintering at last until reaching certain requirement under same temperature under same temperature control subsequently.Whole technical process is mainly finished by the wide cut cement dipping machine.
The utility model poly tetrafluoroethylene material.Its performance indications are
Serviceability temperature :-55 ℃～260 ℃ tearing strength: 〉=300N/5cm
Elongation at break: warp-wise 5.0% broadwise 13.0% tensile strength 〉=5000N/5cm
The utility model film material is a kind of brand-new architecture structure form, and he collects architecture, structural mechanics, fine chemistry industry and materialogy, computer technology etc. is one, has very high technology content; Have big, the good fire line and the self-cleaning of resistance to ag(e)ing, visible space of advantages of higher tensile strength, excellence, thereby prolonged the service life of film material.The utility model film material can be widely used in the ceiling of various sports equipments, large-scale stadium and public building.
Description of drawings: accompanying drawing is the utility model structural representation.
Among the figure 1, upper strata mixed layer 2, glass fibre layer of cloth 3, lower floor's mixed layer
The specific embodiment: the glass fibre ply gage is 0.45mm, and upper strata mixed layer thickness is 0.2mm, and lower floor's mixed layer thickness is 0.2mm; Mixed layer is made up of ptfe emulsion, silica and compatilizer, ptfe emulsion: silica: the proportioning of compatilizer is 100: 10: 0.4.
