Abstract
The utility model discloses a triple extrusion light shading PPR (pentatricopeptide repeats) pipe for a water supply pipeline, which comprises a PPR inner layer, a light shading intermediate layer and a PPR outer layer. Due to the adoption of the triple extrusion light shading PPR pipe, not only can the advantages of light weight, good hygiene, long service life, safe and reliable connection and convenience in construction be kept, but also the color of the product can be diversified when the light shading property of the pipe is ensured. The requirements of people on water quality and the appearance of the product in daily life are met.
Description
Technical field
The utility model relates to the plastic tube technical field, the PPR tubing of the usefulness that is specifically related to feed water.
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 newly-built dwelling construction in cities and towns at home, apply 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.Total consumption accounts for the 60%--70% that all hot and cold waters are carried plastic tube.
Existing PPR tubing is that outward appearance is the single layer structure of white, under sunlight direct projection condition, grows moss in the pipe easily, pipe plug plug in causing.In order to reach shaded effect; Also some tubing adds dark look mothers such as grey mother, though can play certain interception, shading rate is low; And it is extremely inharmonious with white metope color; In view of above situation, be necessary to develop and a kind ofly can guarantee shaded effect, the appearance color can diversified PPR tubing.
The model utility content
The purpose of the utility model is to overcome the deficiency of above-mentioned existing technology, provides a kind of color various, again can the three-layer co-extruded shading PPR of light blocking tubing.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of three-layer co-extruded shading PPR tubing, said pipe structure are combined closely by PPR skin, shading mesosphere and PPR internal layer and are formed.
The thickness in said shading mesosphere is the 20-30% of pipe thickness.
Said shading mesosphere is that 0.5%-3% nanometer carbon black and 97%-99.5% polypropylene are formed by weight percentage.
Said PPR skin is in the PPR raw material, to add and the female extruding and moulding of the look of metope color coordination.
The beneficial effect of the utility model is: 1, keep light weight, the wholesomeness of PPR pipe good, long service life, attachment security is reliable and advantage such as easy construction; 2, can effectively prevent under light direct projection condition tubing printing opacity and grow moss, the shortcoming that causes pipeline blockage and water quality to reduce; 3, can satisfy people to the diversified requirement of product colour outward appearance.
Description of drawings
Fig. 1 is the structural representation of a kind of three-layer co-extruded shading PPR tubing of the utility model.
Embodiment
Below in conjunction with accompanying drawing and practical implementation example a kind of three-layer co-extruded shading PPR tubing of the utility model is done further explain.
Please with reference to Fig. 1, a kind of three-layer co-extruded shading PPR tubing of the utility model,, shading mesosphere 2 outer 3 by PPR and PPR internal layer 1 are combined closely and are formed.
The thickness in said shading mesosphere 2 is the 20-30% of pipe thickness.
The preparation method of the utility model is following:
The proportion requirement of at first nano level superfine carbon black and acrylic resin being pressed 3:97 is mixed, and fully stirs 3min with homogenizer, and through the double screw extruder extruding pelletization, processing temperature is controlled between 170-230 ℃, obtains shading mesosphere PP Pipe Compound then.In the PPR raw material, adding an amount of look female, fully stirs 3min with homogenizer, and through the double screw extruder extruding pelletization, processing temperature is controlled between 170-230 ℃ then, obtains the outer PP Pipe Compound of PPR.Then adopt three-layer co-extruded compound extrusion equipment, in main extruder, drop into the outer PP Pipe Compound of PPR, processing temperature is controlled between 180-230 ℃, and rotating speed is 60-90r/min, extrudes PPR outer 3.Two auxilliary extruders drop into shading mesosphere PP Pipe Compound and PPR raw material respectively, and processing temperature is controlled between 180-230 ℃, and rotating speed is 30-50r/min, extrude shading mesosphere 2 and PPR internal layer 1.Three layers of melt composite co-extruding moulding in co-extruding mould, speed of production is 5-15m/min.Obtain the three-layer co-extruded shading PPR tubing of the utility model again through typing, cooling, cutting.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technological scheme and the design of above description.
Claims (2)
1. a three-layer co-extruded shading PPR tubing comprises body, it is characterized in that: said body is combined closely by PPR internal layer, shading mesosphere and PPR skin and is formed.
2. three-layer co-extruded shading PPR tubing according to claim 1, it is characterized in that: the thickness in said shading mesosphere is the 20-30% of pipe thickness.
