Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of scratch resistant polybutene tubing in surface and its system
Preparation Method.
Background technology
In polyolefin pipe, polyethylene (PE) and polypropylene (PP) pipeline are widely used in Building Cooling water feedwater piping system
System, and it is all polybutene (PB) pipeline of polyolefin family, although " plastics gold " is referred to as by plastic industry, with than PE and PP
Higher bearing strength and more soft advantage easy to install, but in fact, from the beginning of 2000, PB pipelines are completely from America
With Australia market exit, present European market also has very small amount pressure-bearing plastic pipe road to manage using PB, domestic also to also have Beijing etc. few
Number area is being used to build interior heating using PB pipelines.
Polybutene (PB) pipeline is to compare with PE with PP the reason for Building Cooling water field is not widely used, PB
Pipeline is very soft, and surface is easily scratched, and due to the unique crystalline textures of PB, the part being scratched forms stress concentration, in short-term
The intensity of the interior part will drop to below the design pressure of tubing, and pipe explosion accident occurs.
Unique crystalline texture of PB provides the high calorific intensity of PB, for asking of solving that PB pipe surfaces are easily scratched
Topic, once has research using three-decker PB tubing, one layer of PUR is coated outside main body PB tubing and one layer wear-resisting poly-
Alkene coating, eventually because the mechanical property difference of wear-resistant coating and PB bodies is excessive cannot life-time service.
The content of the invention
It is an object of the invention to provide scratch resistant polybutene tubing in a kind of surface and preparation method thereof, leads in the present invention
Cross the formula to PB tubing to design so that designed PB tubing has the case hardness of close PE tubing and high surface light
Cleanliness, while forming one layer of self-lubricating layer in PB tube surfaces, reduces coefficient of friction, improves PB tube surfaces hardness and table
Face fineness, the scratch resistant performance for finally making PB tubing is greatly improved.Simultaneously the present invention can greatly accelerate the crystallization of PB resins
Speed, reduces the production cost of tubing manufacturer.The present invention is conducive to PB tubing in the extensive application in Building Cooling water field.
In order to realize foregoing invention purpose, technical scheme is as follows：
It is an object of the invention to provide a kind of scratch resistant polybutene tubing in surface, in terms of mass fraction, including organic open
0.1～1.5 part of functional stuffing after 0.1～1.5 part of agent of mouth, 97～99.8 parts of polybutene base material and surface treated, it is described
Functional stuffing is microballon light filler or glass microballoon, and described organic opening agent is oleamide or erucyl amide.
Preferably, described microballon light filler is mica iron pearl essence or Muscovitum titanium dioxide pearl essence.
The present invention selects organic opening agent and the functional master batch of increase PB case hardnesses to make special mother by mixing granulator
Grain, then adds 1%～5% special master batch, the tubing extruded to have higher case hardness, table in tubing production
Face fineness and self-lubricating coat in use.
After organic opening agent is dispersed in PB base materials, can be from the migration of trend tube surfaces, so as to form one in tube surfaces
The smooth coating of layer, effectively reduces the coefficient of friction of tube surfaces, forms protective layer, organic opening agent present invention preferably oleamide
And erucyl amide.
Improve the composition of polybutene tubing case hardness, prioritizing selection microballon light filler of the present invention.Microballon light filler it is interior
Core is Muscovitum, and outer layer is the metal-oxide of high index of refraction, can form parallel distributed multiplayer architecture in polybutene tube surfaces,
Both the surface smoothness of polybutene tubing can have been improved, tube surfaces hardness can have been increased again.If the scratch resistance of true qualities need to be produced
PB tubing, increase PB tube surfaces hardness composition prioritizing selection glass microballoon, with microballon light filler identical effect.
Another purpose of the invention is to provide a kind of preparation method of the scratch resistant polybutene tubing in surface, including following
Step：
(1) functional stuffing is surface-treated with vinyl silanes, then by the functional stuffing 0.1 after surface treatment～
0.4～4 part of 1.5 parts, 0.1～1.5 part of organic opening agent and polybutene base material are according to the mass fraction in parallel equidirectional two-screw

(2) with step (1) be obtained special master batch and PB base materials according to 130 DEG C of the proportioning that mass ratio is 1/99～5/95～
155 DEG C of extrusion PB tubing, obtained PB tubing is stood still for crystals after 8～16h, that is, obtain the scratch resistant polybutene tubing in surface.
Preferably, the step of functional stuffing after described surface treatment is surface-treated be：By vinyl silanes：Acetone：
Water is 5 according to mass ratio:94:1 ratio mix homogeneously, functional stuffing is immersed in the vinyl silane solution of mix homogeneously,
5～10min is soaked under room temperature, is filtered dry solution after the completion of immersion, that is, the functional stuffing after being surface-treated.Microballon light filler
Kernel be Muscovitum, outer layer for high index of refraction metal-oxide, can form parallel Multi-layers distributing in polybutene tube surfaces
Structure, can both improve the surface smoothness of polybutene tubing, and tube surfaces hardness can be increased again.
Oleamide and erucyl amide can form cooperative effect with microballon light filler, greatly improve produced PB tubing
Crystalline rate, crystallization time is reduced to 8～16h by the 72h of conventional PB tubing；According to other species opening agents, such as support
Bis-stearamides, the PB tubing of the surface scratch resistant that equally can be made, but the crystalline rate of PB tubing can not be significantly improved.
Preferably, described functional stuffing is microballon light filler or glass microballoon, and described microballon light filler is mica iron
Pearl essence or Muscovitum titanium dioxide pearl essence.
Preferably, described organic opening agent is oleamide or erucyl amide.
The invention has the beneficial effects as follows：The present invention is designed by formula, makes polybutene (PB) tubing have higher surface
Hardness and surface smoothness, while forming one layer of self-lubricating layer in PB tube surfaces, effective protection PB tubing is being installed and used
In be not scratched；The crystallization time of polybutene (PB) tubing can also be greatly decreased；Simultaneously the formula designed by the present invention is to PB
Original excellent physical and chemical performance does not have any damage.
