Abstract
A composite steel-plastic section is composed of two shaped steel liners and thermal insulating plastics. Its preparing process includes making steel liners, co-extrusion of steel and plastics, and surface treatment. Its advantages are simple preparing process, low heat conductivity, and high thermal insulation.
Description
Technical field
The present invention relates to a kind of construction steel plastic door and window section bar technical field, especially steel lining is the energy-saving heat preserving composite material and the manufacture method thereof of discontinuous.
Background technology
At present, the steel plastic door and window is anticorrosion with it, anti-wind pressure good, and nonferrous metal resource consumption has replaced early stage common steel sash and alumium alloy door and window less, is widely used in dwelling house and industrial and mining enterprises.Existing composite steel-plastic sections mainly contains disclosed ZL982049838 on October 20th, 1999 " a kind of steel and rigid foamed co-extrusion profile shapes ", it organically combines high mechanical properties and the working of plastics advantage in light weight, erosion-resisting that steel possess, and has remedied the deficiency of steel sash and aluminum window.But its case hardness is low, easily produces cut, because the thermal expansion coefficient difference of steel and plastics is big, steel lining and plastic basis material are easy to generate delamination and ftracture again.Disclosed ZL012269972 on March 13rd, 2002 " environment-friendly type steel frame hollow profile shapes " on section bar surface-coated magnetic glazing top layer, has improved the intensity and the ageing resistance on section bar surface, but that steel lining and plastic basis material easily produce the problem of delamination is still unresolved.Aforesaid two kinds of section bar products also have common shortcoming: the one, and steel lining is the integral sealing formula, and manufacturing procedure is many, and heat transmits fast by steel lining, and the door and window heat insulating ability of making is poor, and is not energy-conservation; The 2nd, after the group angle becomes door and window, the steel lining boring, the bight bonding strength is low.Therefore, people expect low, the good heat preservation performance of a kind of coefficient of thermal conductivity, and the steel lining manufacturing is simple, intensity high composite steel-plastic sections in bight behind the group angle.
Summary of the invention
Steel plastic door and window section bar heat insulating ability is poor in order to overcome in the existing background technology field, the low deficiency of intensity behind the group angle, the invention provides a kind of steel lining is discontinuous, low, the good heat preservation performance of coefficient of thermal conductivity, and steel lining inside is the composite steel-plastic sections of real core integral type behind the soldering group angle.
The technical solution adopted for the present invention to solve the technical problems is: composite steel-plastic sections comprises steel lining and plastic basis material, it is characterized in that steel lining by two independently the steel profile shapes constitute, two steel profile shapess are connected by working of plastics.
Described working of plastics is the heat insulation connection strap that the cross section is " worker " font.
Described working of plastics is the heat insulation connector of cast polyurethane.
Described plastic basis material tool surface-treated layer.
Described surface-treated layer is the PVC weatherability film, tool natural wood grain effect.
Described surface-treated layer is spraying of fluorine charcoal or glazing spraying, the various colors of tool.
The manufacture method of composite steel-plastic sections of the present invention comprises system steel lining, steel-plastic coextrusion and surfacing three phases, it is characterized in that making steel lining and be two independently the steel profile shapes be formed by connecting by working of plastics is heat insulation.
Described is to be formed by connecting to wear the bar mode with the heat insulation connector that the cross section is " worker " font by the heat insulation connection of working of plastics.
Described is to be formed by connecting with pouring type with hot melt polyurethane by the heat insulation connection of working of plastics.
Composite steel-plastic sections of the present invention, steel lining by two independently the steel profile shapes constitute, the steel lining manufacturing is simple, manufacturing procedure reduces, and two profile shapess are connected by the working of plastics of good heat-insulation effect, the coefficient of thermal conductivity of product of the present invention is reduced, heat insulating ability improves, behind the soldering group angle, the working of plastics that connects profile shapes is melt into one, and bight intensity height can be widely used in industry and the civilian construction door and window.

The specific embodiment
As shown in Figure 1, 2, composite steel-plastic sections of the present invention comprises plastic basis material 1 and by two steel linings of constituting of steel profile shapes 2,3 independently, is connected by working of plastics 4 between the steel profile shapes 2,3.
Steel lining of the present invention by two independently steel profile shapes 2,3 constitute, make difficulty and reduce greatly than integral sealing formula steel lining, manufacturing procedure reduces.The good effect of heat insulation of working of plastics 4 tools between the steel profile shapes 2,3 improves the heat insulating ability of product of the present invention, and energy-saving effect is obvious.Plastic basis material 1 surface forms surface-treated layer 5 after treatment, PVC weatherability film wherein, and tool natural wood grain effect is through spraying of fluorine charcoal or glazing sprayed coating, the various colors of tool.When product of the present invention adopts thermal weld mode group angle, but working of plastics 4 hot melts of adjacent profiles be integral, the bonding strength in bight is improved.
Working of plastics 4 among Fig. 1 is heat insulation connection straps that the cross section is " worker " font, it is after being through between the steel profile shapes 2,3 earlier, is made by co-extrusion to product of the present invention again.
Working of plastics 4 among Fig. 2 is the heat insulation connectors of cast polyurethane, it is after forming with hot-melt plastic cast between the steel profile shapes 2,3, is made by co-extrusion to product of the present invention again.
Make the method for composite steel-plastic sections of the present invention, comprise system steel lining, steel-plastic coextrusion and surfacing three phases, system is meant that the plastics thermal insulation barriers that is " worker " font with the cross section wears bar and be formed by connecting the steel lining stage between two profile shapess 2,3, make steel lining as shown in Figure 1.Form between two profile shapess 2,3 with the hot melt cast polyurethane, make steel lining as shown in Figure 2.After making steel lining, steel-plastic coextrusion becomes composite material, surfacing is become the PVC weatherability film again, produces the natural wood grain effect.Various colors are made in surface fluorine charcoal spraying or glazing spraying.
Fig. 3 to Figure 10 be use the technology of the present invention produce flat-opening window-leaf material, push-and-pull fan material, push-and-pull frame material and in the sectional view of section bar very, its internal construction, manufacture method are identical with Fig. 1, Fig. 2, also belong to the scope of protection of present invention.
In sum, composite steel-plastic sections of the present invention will be broken into two independently behind the steel profile shapes between the whole steel lining in the prior art field, and difficulty of processing reduces, and operation reduces.Two steel profile shapess are by the heat insulation connection of working of plastics, make that this product tool coefficient of thermal conductivity is low, good heat preservation performance, advantage such as energy-conservation.Behind the sweat soldering group angle, the working of plastics that connects profile shapes is melt into one, bight intensity height.
