Description

Combined type energy-saving doorframe or Door leaf frame

Technical field

The utility model relates to a kind of high strength, low-gravity, insulation, thoroughly microwave, corrosion-resistant, good heat-insulation effect and ornamental strong combined type energy-saving doorframe or Door leaf frame, belongs to combined type energy-saving doorframe and door leaf frame section manufacturing and application.

Background technology

At present, popular building doors and windows on the market, the main door and window that adopts the materials such as wood, aluminium alloys, plastic-steel, bridge-cut-off aluminum, wooden aluminium is compound or plastic-aluminum combined.The coefficient of thermal conductivity of timber is 0.15 kal/ (m ²Hk), thereby have fabulous insulation, heat insulation, ornamental, but the sealing performance of wooden door and window is relatively poor, timber is water funk and exposure in sunshine, the easy moisture absorption and deformation of timber in wet environment; The coefficient of thermal conductivity of aluminium alloys is 187 kal/ (m ²Hk) about, its heat conductivility is fabulous, thereby the heat-proof quality of made door and window is relatively poor; The coefficient of thermal conductivity of plastics is (0.2～0.13) kal/ (m ²Hk), its heat conductivility only has the one thousandth of aluminium alloys, and plastic irregular profile can weld, and plastic-steel door and window has good insulation, sealing, heat insulation performance, but the decorate properties of plastics is relatively poor.

Bridge-cut-off aluminum adopts nylon material with two original aluminium alloy deformed bar bridge joints together, thereby the inside and outside thermal source of doorframe and window frame disconnects, and reaches the loss that reduces energy, and the sealing performance of its door and window is compared with common aluminum alloy does not have basic change; The performance of the door and window that wood aluminium is compound improves a lot, but door and window in use, and rainwater can contact with the timber in the door and window, and the time has been grown timber can mouldy or distortion.Although plastic-aluminum combined do not have because phenomenon mouldy or distortion can occur rainwater, the interior decoration poor-performing of door and window, and it is yielding, easily aging to be heated.

Glass fiber reinforced plastic door and window namely adopts unsaturated polyester resin and glass fiber compound, the window and door system that processes.Unsaturated polyester resin is a kind of thermosetting resin, when its under the effect of heat or initator, curablely become a kind of insoluble macromolecule network polymers that does not melt.But this polymer machinery intensity is very low, can not satisfy most of requirement of using, and can become a kind of composite material when strengthening with glass fiber, is commonly called as " glass fiber reinforced plastic " (English name Fiber Reinforced Plastics is called for short FRP).The various aspects of performance such as mechanical strength of " glass fiber reinforced plastic " are compared with casting resin and are greatly improved.But unsaturated polyester resin glass fiber reinforced plastic profile shapes when will add longitudinally glass fiber, also must add the glass mat body in the pultrusion manufacturing process, thereby its speed and efficient are lower; Simultaneously can produce a small amount of styrene aborning.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design a kind of high strength, low-gravity, insulation, thoroughly microwave, corrosion-resistant, good heat-insulation effect and ornamental strong combined type energy-saving doorframe or Door leaf frame.

Design scheme: in order to realize above-mentioned purpose of design.The application utilizes polyurethane and glass fiber compound, it is the polyurethane glass steel composite material, this compound polyurethane material has extraordinary physical and mechanical properties, can the Substitute For Partial metal, use is in field very widely, so the application is its design gate window frame or door leaf frame section, its polyurethane doorframe, Door leaf frame not only have good impact strength, and stop infiltration of rainwater very good, the more important thing is that the performance aspect thermal insulation is then even better.
