Description
Technical field
The present invention relates to a kind of plastic conduits and preparation method thereof, belong to communication conduit road field.
Background technology
Under the overall situation that New Town Construction and old city transformation are actively developed in current various regions, the laying of underground communication pipeline also exists
A large amount of to carry out, the type pipeline is often used for protecting cable under roadbed, and product includes 4 holes, 5 holes and 6 holes, and product is mostly darkly
Color, fire-retardant, intensity reaches the intensity of steel pipe.Underground piping laying has higher requirement to the mechanical property of pipeline itself, needs
Carry out many index test, such as tensile strength, return rate, tubing rigidity, flat experiment etc..In order to adapt to above-mentioned want
It asks, pipeline not only needs rationally to select in terms of material materials, and structure design is also required to consider.
Application No. is 201510859922.2 Chinese patents to disclose a kind of enhanced polyethylene compound pipe road, passes through
Carbon steel layer from outside to inside, high-density polyethylene layer and ultra-high molecular weight polyethylene layer three-layer composite structure realize the resistance to of pipeline
Mill, impact resistance are corrosion-resistant.The compound pipeline complex pipeline of this structure type is since independently of each other, no interaction belongs between each layer material
Simple superposition, each layer keep the performance characteristics of its own, and therefore, overall performance is poor.
Application No. is 201510724171.3 Chinese patents to disclose a kind of plum tube and preparation method thereof, from tubing
Improvement is proposed on raw material ratio direction, based on high-density polyethylene resin, is added to plasticizer, stabilizer, filling
Material, stearic acid and paraffin still depend on high density polyethylene (HDPE) tree with plum tube substantially its mechanical property prepared by the formula
Fat, remaining additive facilitate forming and increase wear-resisting property.
Application No. is 201610207005.0 Chinese patents to disclose a kind of enhanced polybutene pipeline material and its system
Preparation Method, maximum feature are the introduction of carbon fiber as hardening constituent, impact, toughness and elasticity greatly improved, but
Its defect is also quite apparent, and the cost of raw material is very high, and configuration process is complicated, and dispensing is more, and market price competition advantage is little.
Comprehensive technical solution disclosed currently on the market, substantially there is two major features：
（1）In order to improve mechanical property or be added carbon fiber or improve density of pe grade, cause price at
Originally it is significantly increased；
（2）In order to ensure that properties balance, do not occur apparent short slab, while ensureing that forming process is smooth, and must increase
Add new additive, then the type and quantity of additive are significantly increased, and blending process complicates, and uncontrollable factor increases.
In view of the foregoing, it is applicant's understanding that can start with from pipeline configuration and material formula simultaneously, ensureing mechanics
Under the premise of performance and chemical property, pipeline manufacturing cost is reduced, simplifies preparation process.
Invention content
The technical problem to be solved by the present invention is to：A kind of underground communication plastics used for pipe pipe is provided, formula is simple, prepares work
Skill is simple, and cost is smaller compared to existing tubing amplification, but high mechanical properties have considerable promotion, anti-aging property to have essence to carry
It rises.
Technical scheme is as follows：
A kind of underground communication plastics used for pipe pipe, component are calculated according to mass percent, including：
High density polyethylene (HDPE)：80% 90%, and high density polyethylene (HDPE) grade is 100 grades or 100 grades or more；

Silicon powder：4%〜9%；
Halogen-free flame retardants：1%〜5%；
Uv age resisters：1% 4%, and uv age resisters are by BASF Tinuvin400, Tinuvin327 and
Chimassorb81 is formed, and the mass ratio of three is 1 ︰, 4 ︰ 1.
Above-mentioned silicon powder includes crystallization silicon powder, melts silicon powder and cristobalite silicon powder, and the mesh number of silicon powder is more than etc.
In 800 mesh, SiO2Content（Mass fraction）More than or equal to 99.5%.
The powder of raw material or particle are mixed according to above-mentioned material proportioning, single screw rod is stirring evenly and then adding into and squeezes
Pressing formation machine, forming temperature are controlled at 160 DEG C 300 DEG C, are pulled out by traction and are directly gone out finished product after water cooling and cut into
Material.
On the other hand, in order to improve the mechanical property of existing plum blossom pipeline from structure, the present invention is in existing plastic tube
It is improved in structure, first, it is desirable that plastics pipeline outer wall thickness is more than inner wall thickness（Pipeline outer wall refers to whole pipeline
Outer surface, inner wall refers to the inner surface of whole pipeline, it is generally the case that a plastics pipeline is by 4 root pipes or 5
Root pipe, then 6 root pipes composition, be referred to as 4 holes pipe, 5 holes pipe and 6 holes pipe）；Second, it is increased on pipeline
The position of reinforcing rib, reinforcing rib is located at the intersection of adjacent two pipes, and is distributed in intersecting lens both ends, reinforcing rib both ends of the surface point
Circular tube external wall connection is not intersected with two.
Thin outer thickness, on the one hand can mitigate certain dead weight in plastics pipeline wall（Relative to increase reinforcing rib after increase
Weight）, on the other hand save material.
It is preferably selected as one kind, the section of reinforcing rib is in sector, arc-shaped outer surface convex（I.e. with two pipes
Intersecting lens on the basis of, the midpoint of intersecting lens is origin, at this point, the normal direction of arc-shaped outer surface is directed toward by origin outside arcwall face
Surface）.
It is preferably selected as one kind, the arc radius of the outer surface of reinforcing rib is R8mm R12mm, and conference excessively causes cold
But pipe deforming is scrapped during.
The material component of reinforcing rib is identical as plastics pipeline material.
The marked improvement of the present invention is embodied in the following aspects：
1. the plastics pipeline of the present invention need not be set with steel pipe in outermost layer can meet intensity requirement, by test, originally
The tensile strength of invention is more than or equal to 20MPa, is higher than requirements of the professional standard YD/T841.5-2008 for HDPE class tubing；Pipe
In terms of material rigidity, the present invention reaches 3000kPa, is higher than the regulation of professional standard YD/T841.5-2008；Flattening test result table
Bright, when vertical direction elemental height deflection of the present invention is 80%, sample crack-free after unloading immediately, remaining index is satisfied by YD/
The requirement of T841.5-2008.
2. the present invention is on the basis of high density polyethylene (HDPE), the additive quantity of addition is few, and price is relatively low, produces work
Skill is simple, and quality control is simple and practicable.
3. the unique age resister formula of the present invention being capable of the substantive anti-aging property for improving shaped pipe.
