Abstract

The utility model discloses a composite co-extrusion door and window special-shaped profile. A special-shaped steel lining is wrapped in a PVC micro-foamed plastic layer 2, and the section of the special-shaped steel lining is fully enclosed. The design key point of the special-shaped profile is that an ASA/PMMA layer is coated on the outer surface of the PVC micro-foamed plastic layer. The composite co-extrusion door and window special-shaped profile has good weather enduring property, cannot be easily aged, cannot easily fade, and can meet the need of diversified colors.

Description

A kind of composite co-extruding door and window profile material

Affiliated field:

The utility model relates to profile shapes, specifically a kind of composite door and window frame profile shapes.

Background technology:

The steel-plastic coextrusion profile shapes is an emerging sash stuff at the end of the nineties in last century, because of its intensity height and the good extensive favor that is subjected to industry deeply of heat insulation property.Present steel-plastic coextrusion profile shapes is made by co-extrusion to by two layers of material usually.Its skin is the PVC micro-foamed plastic, and internal layer is a galvanized steel plain sheet, and the two directly is combined with each other in mould when plastics are extruded.Because it is poor to be attached to the PVC micro-foamed plastic weatherability on steel lining surface, under the acting in conjunction of aerial acid/alkaline matter and ultraviolet ray irradiation, very easily wear out, fade in the section bar surface.Especially when section bar exposed in outdoor environment, its degree of aging was serious further, had therefore also had a strong impact on the extensive use of this profile shapes.In addition, along with improving constantly of people's esthetic requirement, when building and indoor decoration design, usually need the inside and outside color difference of door and window.And can only be with a kind of color inside and outside the double-deck steel-plastic coextrusion profile shapes, therefore be difficult to satisfy the needs of modern decoration design.

The utility model content

The purpose of this utility model will provide a kind of composite co-extruding door and window profile material exactly, and this section bar has good weatherability, is difficult for wearing out, fading, and can satisfies multicoloured needs.

Composite door and window frame profile shapes provided by the utility model, being coated with section in the PVC micro-foamed plastic layer 2 is totally enclosed special-shaped steel lining, its design main points are that the appearance at PVC micro-foamed plastic layer is covered with the ASA/PMMA layer.

ASA described in the utility model is a kind of ter-polymers of being made up of acrylonitrile, styrene, acrylic rubber.PMMA is the polymethyl methacrylate that is polymerized by methyl methacrylate monomer.

The composite co-extruding door and window profile material of the co-extruding mould manufacturing that employing the utility model provides is formed by the trilaminate material composite co-extruding.Its outside at common steel-plastic coextrusion profile shapes has increased one deck ASA (PMMA) material, has strengthened the weatherability of steel-plastic coextrusion profile shapes thus greatly, and having overcome existing steel-plastic coextrusion profile shapes is the PVC plastic layer because of the surface, easily the defective of weather stain.

Test data of experiment shows that the utility model is about 2.1 through 6000h test Δ E value, and to test Δ E value be about 4.6 and ordinary steel is moulded the 4000h of composite co-extruding door and window profile material.

In addition, the composite co-extruding door and window profile material that the utility model provides, its outside visible surface is ASA (PMMA) layer, inboard visible surface is the PVC plastic layer, can realize the configuration of the inside and outside different colours of door and window thus, thereby both can satisfy the needs that indoor furniture is decorated, can take into account the needs of Exterior Design style again.Accomplish that a kind of section bar is satisfied in many ways.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

As shown in Figure 1, being coated with section in the PVC micro-foamed plastic layer 11 of the present utility model is totally enclosed special-shaped steel lining 10, is coated with ASA/PMMA layer 12 in the appearance of PVC micro-foamed plastic layer 11.When making the utility model, need to adopt corresponding steel-plastic coextrusion mould.This mould such as Fig. 2, shown in Figure 3, form by runner plate 1, mouth template 2, compressive plate 3, supporting plate 4, core 13, compressive plate 3, mouth template 2 all have die cavity, and the gap between compressive plate 3, mouth template 2 and the core 13 constitutes PVC materials flow road 8, and core 13 inside have steel lining passage 9.Between runner plate 1 and mouth template 2, be provided with ASA inlet 5.In the side (being the section bar upper surface in this example) of need coating ASA (PMMA), leave ASA/PMMA materials flow road 6 on the runner plate 1, these runner 6 slit-shaped ASA charging apertures 7 terminal and that longshore current guidance tape die cavity edge is offered communicate; ASA materials flow road 6, PVC materials flow road 8, steel lining passage 9 converge at mouth template 2 front ends.In order to strengthen the even distribution of ASA material, as Fig. 4, shown in Figure 5, said ASA materials flow road 6 preferably distributes and is semicircle shape, and ASA materials flow road 6 dwindles to the die cavity direction gradually with the gap of adjacent mouth template 2.End in this example is reduced to 0.15～0.2mm; The front end in said ASA (PMMA) materials flow road 6 and section is semi-circular or the dispersion pilot flow 15 of ladder type links disperses the end of pilot flow 15 to extend to and coats the required highest distance position of ASA.ASA (PMMA) charging aperture 7 gaps can be made as 0.15～0.2mm, and width is 4～8mm.In process of production, as shown in Figure 3, the PVC materials flow moves forward into PVC materials flow road 8 by supporting plate 4 rear ends, advances along PVC materials flow road 8.Meanwhile, steel lining 10 is through steel lining passage 9 advanced in unison; ASA (PMMA) material enters ASA (PMMA) runner 6 and disperses pilot flow 15 by ASA (PMMA) inlet 5, flows to ASA (PMMA) charging aperture 7 from different directions.ASA (PMMA) materials flow, PVC materials flow, steel lining 10 threes converge at the mouth template front end, enter composite log 14.Be in the PVC plastics abrupt release pressure that compressive state is full of saturated bubble through compressive plate, foaming and intumescing, above with ASA, followingly closely be compound to steel lining, extrude jointly, form composite co-extruding door and window profile material as shown in Figure 1, this different this section bar is steel backing layer 10, PVC micro-foamed plastic layer 11, ASA/PMMA layer 12 from inside to outside successively.Adopt the profile shapes of the utility model manufacturing to be not limited in abnormal shape shown in Figure 1.Special-shaped shape can be decided according to different purposes and function.

Claims

1. composite co-extruding door and window profile material, being coated with section in the PVC micro-foamed plastic layer (11) is totally enclosed special-shaped steel lining (10), it is characterized in that the appearance of PVC micro-foamed plastic layer (11) is coated with ASA/PMMA layer (12).
