Abstract
The invention discloses a heat-insulation metal section bar with a foaming attached strip in a cavity and a manufacture method thereof. The method is characterized in that polystyrene foam is injected into a prefabricated U-shaped groove or V-shaped groove, and the U-shaped groove or the V-shaped groove with glue is simultaneously inserted into a heat-insulation cavity. The manufacture method comprises the following process steps: plugging two ends of the U-shaped groove or the V-shaped groove; injecting the polystyrene foam into the U-shaped groove or the V-shaped groove; putting the U-shaped groove or the V-shaped groove filled with the polystyrene foam into the heat-insulation cavity of the section bar; and heating and solidifying. According to the invention, the problem that heat-insulation property is reduced because of air convection can be overcome by filling the polystyrene foam into the cavity of the section bar, therefore the heat-insulation metal section bar with a foaming attached strip in a cavity, which is provided by the invention, has good heat-insulation property and structural strength,.
Description
Technical field
The present invention relates to have in a kind of die cavity the heat insulating metal section bar and the manufacture method thereof of attached of foaming, belong to Door for building window material technical field.
Background technology
In the prior art, between the inside and outside shape of door and window, reach heat insulation mutually, following dual mode is generally arranged:, be pressed into therebetween with the plastics cutting is slotting in some way one, at shape thermal insulation bridge cut-off place.Space in the heat insulating strip cavity of penetrating bar type use in construction of door and window heat-insulation aluminum section is bigger, though big cavity can effectively overcome radiant energy and conduction of heat, and, the convection current that has increased air has equally reduced the heat-proof quality of section bar thus.This heat insulation mode and since the section bar of plastics between transplanting a cutting be discrete, be hollow again, its sealing performance is bad, anti-steam weak effect; And only depend on plastics to transplant a cutting and connect two kinds of shapes, its comprehensive strength is low, and there is obvious defects in this structure.Two,,, inside and outside shape is fused with polyurethane structural foam or microporous polyurethane foam at two kinds of shape thermal insulation bridge cut-off places.This kind structure reduces the heat-insulation chamber structural strength owing to use foaming or microcellular foam material greatly, for guaranteeing bonding strength, and can only be to increase the deficiency that the heat-insulation chamber volume remedies intensity; Be filled with heat-insulation chamber with polyurethane structural foam or microporous polyurethane foam, exist production efficiency low, easily produce bubble and waste product occurs, yield rate is hanged down problem.
The patent No. is that ZL200420031427.x patent of invention manual discloses a kind of strength energy-saving heat insulating metal section bar, said shape need be provided with heat dam between the position, opposite flank of heat insulation connection at it, heat dam top has notch, is filled with the hard heat-insulating resin in the heat dam and forms heat insulation bridge.The notch of above-mentioned heat dam and bottom inside face thereof are provided with dowel; The dowel spacing of heat dam bottom is identical with width of rebate.At the heat dam cavity inner surface is rough surface, and this surface can be designed to shapes such as corrugated or zigzag.Be provided with the metal otch between bottom two dowels of above-mentioned heat dam, this otch forms after excising the heat dam bottom metal with cutting tool.Although this section bar heat-proof quality is good, the processing technology complexity, and the heat insulation bridging of shape to connect intensity low.
In sum, existing Thermal insulation door and window shape, exist respectively heat insulation, sealing is bad, comprehensive strength is low or the heat-insulation chamber volume big, production efficiency and the low shortcoming of yield rate, is difficult to satisfied both energy-saving heat-insulatings, has the demand of the constructional materials of high structural strength again.
Summary of the invention
The present invention has overcome the deficiency of above-mentioned prior art, its purpose is to provide heat insulating metal section bar and the manufacture method thereof that has attached of foaming in a kind of die cavity, this shape can overcome the problem that reduces thermal insulation because of the convection current of air toward perfusion foamed glue in the cavity of wearing the bar heat-insulation aluminum section, and improves and wear bar section bar thermal insulation and structural strength.
Another purpose of the present invention is to provide the manufacture method of the heat insulating metal section bar that has attached of foaming in a kind of die cavity, this method is to inject foamed glue in ready made U type groove or V-type groove, and the U type groove or the V-type groove of injecting glue be inserted in the heat insulation cavity simultaneously, make section bar have good thermal insulation and structural strength simultaneously.
Above-mentioned purpose of the present invention realizes by following technological means.
Have attached heat insulating metal section bar of foaming in a kind of die cavity, comprise that metal wears the bar section bar, it is characterized in that being provided with in the die cavity of said shape attached of the U type groove of filling foamed glue or the foaming of V-type groove.
The manufacture method that has the heat insulating metal section bar of attached of foaming in a kind of die cavity, this method are to inject foamed glue in ready made U type groove or V-type groove, and the U type groove or the V-type groove of injecting glue is inserted in the heat insulation cavity simultaneously.The processing step of above-mentioned manufacture method is: the U type groove of shutoff U type groove or V-type groove two ends → inject in U type groove or V-type groove foamed glue → will be filled with foamed glue or V-type groove are inserted in the heat insulation cavity of section bar → are heating and curing.Under 50 ℃ of temperature condition, the time of being heating and curing was generally 5～10 minutes.
Attached of above-mentioned foaming is to inject foamed glue with dual-component polyurethane (PU) foaming bottling machine in ready made U type groove or V-type groove, and the U type groove or the V-type groove of injecting glue be inserted in the heat insulation cavity simultaneously, dual-component polyurethane has promptly realized improving the purpose of thermal insulation behind foamed solidification.Above-mentioned U type groove or V-type groove can adopt plastics to make.The length that the built-in foaming of above-mentioned die cavity is attached is identical with the die cavity length of shape.
The heat insulating metal section bar that has attached of foaming in the die cavity provided by the present invention utilizes the interior perfusion of the cavity foamed glue of section bar to overcome the problem that reduces thermal insulation because of the convection current of air, and improves and wear bar section bar thermal insulation and structural strength.Method provided by the present invention is to inject foamed glue in ready made U type groove or V-type groove, and the U type groove or the V-type groove of injecting glue is inserted in the heat insulation cavity simultaneously, makes section bar have good thermal insulation and structural strength simultaneously.
