Abstract
The utility model provides a polyvinyl chloride (PVC) rain pipe, in particular to a multicolor coextrusion PVC square rain pipe. The cross section of the PVC square rain pipe is of a square shape and the pipe is formed by overlapping of an inner layer and an outer layer, and the outer layer is a multicolor layer. The cross section of the multicolor coextrusion PVC square rain pipe can be of a rectangular shape. The cross section of the PVC square rain pipe is of the square shape, and the PVC square rain pipe is novel in structure. The outer layer is the multicolor layer and various in color. The PVC square rain pipe is matched with a multicolor building so that the multicolor building is beautiful. Meanwhile, inorganic pigment which is good in weather fastness is adopted in the multicolor layer, so that fresh color can be kept for a long time.
Description
Technical field
The utility model is a kind of PVC rain pipe, particularly the square rain pipe of a kind of color coextrusion PVC.
Background technology
The PVC rain pipe has been widely used in the outdoor buildings storm-water system, present known PVC rain pipe, it is circular that its section mostly is, structure is single, does not satisfy building to the diversified demand of rain pipe section configuration, in addition, existing rain pipe mostly is white, weather resistance is relatively poor, and the rear easy flavescence blackening of exposing to the weather has for a long time affected external attractive in appearance of building.
Summary of the invention
The purpose of this utility model is the defective that has PVC rain pipe structure solid color dullness now in order to overcome, and inventing a kind of section is the square square rain pipe of color coextrusion PVC with multiple color.
The purpose of this utility model realizes as follows: the square rain pipe of described color coextrusion PVC, and its section is square, and this pipe is formed by stacking by internal layer and skin, and its ectomesoderm is color layer.
The section of the square rain pipe of described color coextrusion PVC also can be rectangle.
Good effect of the present utility model is as follows: the utility model section is square, novel structure; Skin is color layer, and color is various, with the collocation of colour building, makes building more attractive in appearance, and the good inorganic pigment of color layer employing weatherability, can keep for a long time gay colours.
Description of drawings
Fig. 1 is cross-section structure of the present utility model
Among the figure: 1 internal layer, 2 skins
The specific embodiment
As shown in Figure 1, the square rain pipe of described color coextrusion PVC, its section is square, and this pipe is formed by stacking by internal layer 1 and outer 2, and its ectomesoderm 2 is color layer.
The section of the square rain pipe of described color coextrusion PVC also can be rectangle.
In implementation, internal layer and skin are to extrude by the two extruders plasticizing respectively, and cooling and shaping forms after square mould co-extrusion merges.The utility model section is square, novel structure; Skin is color layer, and color is various, with the collocation of colour building, makes building more attractive in appearance, and the good inorganic pigment of color layer employing weatherability, can keep for a long time gay colours.
