Abstract
The utility model discloses a double-layer PPR (polypropylene random copolymer) pipe which comprises an inner pipe body and an outer pipe body, wherein the inner pipe body is closely combined with the outer pipe body and is a light shading layer. The inner pipe body is formed by extruding materials capable of shading light, the outer pipe body is formed by adding color masterbatch matching with a wall in color into PPR raw materials and extruding the materials, the double-layer PPR pipe can shade the light, the color of the outer pipe body can be changed according to the requirements of different customers, and accordingly, the double-layer PPR pipe matches with the wall in color and is attractive. The double-layer PPR pipe keeps the advantages of light weight, fine sanitation, long service life, safety and reliability in connection, convenience in construction and the like, and can effectively prevent the shortcomings of pipeline blockage and water quality reduction due to moss breeding caused by light transmission of pipes under the condition of perpendicular incidence of the light. Besides, the requirements of people on diversification of product colors and appearances can be met.
Description
Technical field
The utility model relates to the plastic tube technical field, refers in particular to a kind of double-deck PPR pipe.
Background technique
In December, 1999, the Ministry of Construction of China, State Economic and Trade Commission, building materials office, quality Technical Supervision Bureau unite has assigned " about the notice of the eliminating of outmoded products in dwelling construction ", requirement is from June 1 calendar year 2001, forbid Coating Steel Pipe is used in indoor Pipeline in the construction of cities and towns New Dwelling at home, apply the novel tubes such as atactic copolymerized polypropene (PPR) pipe, aluminium-plastic composite pipe.Therefore the consumption of PPR tubing also increases substantially, and market share improves rapidly, and total consumption accounts for the 60%-70% of all hot and cold water plastic pipe for conveying materials.
Existing PPR tubing is that outward appearance is the single layer structure of white, under the direct sunlight condition, grows easily moss in the PPR pipe, causes interior blockage.In order to reach shaded effect, also some tubing adds the dark look mothers such as grey mother, although can play certain interception, shading rate is low, and extremely inharmonious with white metope color, affects attractive in appearance.
Summary of the invention
The purpose of this utility model provides a kind of double-deck PPR pipe, and it can overcome the deficiencies in the prior art, good shading effect.
The purpose of this utility model is achieved in that
A kind of double-deck PPR pipe, it includes internal layer body and outer body, and described internal layer body and described outer body are combined closely, and described internal layer body is light shield layer.
Described internal layer body selects to play the material extruding and moulding of light shielding property, and described outer body is chosen in the look mother extruding and moulding of adding in the PPR raw material with the metope color coordination, make double-deck PPR pipe both reach shaded effect, again can be according to different clients' demand, change the color of outer body, so that double-deck PPR pipe and body of wall color coordination, attractive in appearance.
Therein among embodiment, the thickness of described internal layer body is the 65-75% of the thickness of whole double-deck PPR pipe, accordingly, the thickness of described outer body is the 25%-35% of whole double-deck PPR tube thickness, make double-deck PPR pipe can either meet the opaqueness requirement of tubing, inner layer color can not melt out the outside of PPR pipe in the time of can guaranteeing hot melt again, affects attractive in appearance.
The utility model compared with prior art has following beneficial effect:
Double-deck PPR pipe of the present utility model has kept not only that the light weight of PPR pipe, wholesomeness are good, long service life, connection is safe and reliable and the advantage such as easy construction, can effectively prevent again under light direct projection condition, tubing printing opacity and grow moss, the shortcoming that causes pipeline blockage and water quality to reduce; On the other hand, can also satisfy people to the diversified requirement of product colour outward appearance.
Description of drawings
Fig. 1 is the structural representation of the double-deck PPR pipe of the utility model.
Embodiment
As shown in Figure 1, the double-deck PPR pipe of the utility model, it includes internal layer body 11 and outer body 12, and described internal layer body 11 and described outer body 12 are combined closely.The thickness of described internal layer body 11 is the 65-75% of the thickness of whole double-deck PPR pipe.
Described internal layer body 11 is that the dark master batch of nanometer of 1%-2% and the atactic copolymerized polypropene (PPR) of 98%-99% mix extruding and moulding by weight percentage; In the present embodiment, the weight ratio of the dark master batch of preferred described nanometer and described atactic copolymerized polypropene (PPR) is 2:98.And described outer body 12 is to add in the PPR raw material and the female extruding and moulding of the look of metope color coordination.
When making described double-deck PPR pipe, the proportion requirement mixing of at first the dark master batch of nanometer and PPR resin press 2:98 is fully stirred 5min with homogenizer; Then by the double screw extruder extruding pelletization, processing temperature is controlled between 170-220 ℃, obtains the PP Pipe Compound of described internal layer body 11.It is female to add an amount of look in the PPR raw material, fully stirs 5min with homogenizer, and then by the double screw extruder extruding pelletization, processing temperature is controlled between 170-220 ℃, obtains the PP Pipe Compound of described outer body 12.Then adopt two-layer coextru-lamination extrusion equipment, drop into described internal layer body 11 PP Pipe Compound in main extruder, processing temperature is controlled between 180-220 ℃, and rotating speed is 60-90r/min, extrudes described internal layer body 11.Drop into described outer body 12 PP Pipe Compound at auxiliary extruder, processing temperature is controlled between 180-220 ℃, and rotating speed is 50-80r/min, extrudes described outer body 12.Two-layer melt is the composite co-extruding moulding in co-extruding mould, and die temperature is controlled between 190-230 ℃, and speed of production is 5-20m/min.Obtain described double-deck PPR pipe through typing, cooling, cutting again.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
1. a double-deck PPR pipe is characterized in that it includes internal layer body and outer body, and described internal layer body and described outer body are combined closely, and described internal layer body is light shield layer.
2. double-deck PPR pipe according to claim 1 is characterized in that the thickness of described internal layer body is the 65-75% of the thickness of whole double-deck PPR pipe.
