Summary of the invention
The utility model, in order to overcome the deficiencies in the prior art, provides the plastic material of polyurethane foam in a kind of die cavity, has solved the problem of the thermal insulation reduction causing because of cross-ventilation, has improved thermal insulation, soundproof effect and the structural strength of plastic door-window.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
In described die cavity, the plastic material of polyurethane foam is comprised of section bar body and polyurethane foaming body, in it is characterized in that in the die cavity of section bar body, be provided with polyurethane foaming body, polyurethane foaming body is full of the die cavity of section bar body, section bar body and polyurethane foaming body are bonded together, the length of section bar body and polyurethane foaming body is identical, polyurethane foaming body is that closed pore hard bubbles, polyurethane is aqueous one-component or two components resin, section bar body adopts PVC plastics to make, the cross section of section bar body has the die cavity of sealing, the die cavity of section bar body is enclosed and is formed by a plurality of faces, and at close-shaped interior filled polyurethane foaming body, polyurethane foaming body is injected in the larger die cavity in space.
The beneficial effects of the utility model are:
In die cavity of the present utility model, the plastic material of polyurethane foam is used for manufacturing plastic door-window, thermal insulation, soundproof effect and structural strength have been improved, replaced steel lining, that makes plastic door-window need to not increase steel lining in plastic material internal cavities, simplify plastic door-window packaging technology, reduced cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model plastic material, and Fig. 2 is section bar body construction schematic diagram.
