Abstract
The invention discloses a silicon core pipe preparation method. The silicon core pipe preparation method is characterized in that during the production process of a silicon core pipe, silicon core master batch and matrix resin HDPE are added to inner layer raw materials traditionally and meanwhile dispersing agent oleamide, assistant dispersing agent glycerin monostearate, processing agent low polymer and processing agent white oil are added, wherein the weight ratio of the dispersing agent oleamide, the assistant dispersing agent glycerin monostearate, the processing agent low polymer and the processing agent white oil is 1 to 1 to 2.5 to 2.5. The silicon core pipe preparation method has the advantages of changing the traditional silicon core layer master batch ratio, enabling the silicon core layer master batch to be uniformly scattered in an inner layer due to the fact that the assistant is added in a composite mode, being free of accumulation, remarkably improving the lubricating performance of the silicon core pipe internal wall and meanwhile reducing enterprise production costs due to the fact that the cost of the composite assistant is lower than that of the silicon core master batch.
Description
Technical field
The present invention relates to silicon core pipe preparing technical field, the preparation method of the silicon core pipe that especially a kind of internal layer silicon core masterbatch is uniformly dispersed, lubricity is good.
Background technology
Silicon core pipe is the NEW TYPE OF COMPOSITE pipeline of a kind of inwall with silica gel matter solid lubricant, good seal performance, and resistance to chemical attack, construction costs is low, is widely used in motorway, the optical cable communications network system of railway etc.HDPE silicon core pipe is the NEW TYPE OF COMPOSITE pipeline of a kind of inwall with silica gel matter solid lubricant, is called for short silicone tube.By three synchronous extrusion claddings of plastics extruder, main raw material(s) is high density polyethylene(HDPE), and sandwich layer is the solid lubricant silica gel matter that frictional coefficient is minimum.
But due to silicon core tube mother material unstable properties, in actual production process, silicon core tube mother material disperses inhomogeneous, there is the vertical striped of different brightness in the silicon core inside pipe wall of producing, and has local accumulation phenomenon, increased friction resistance when optical cable is worn cable.
Summary of the invention
The technical problem to be solved in the present invention is to provide the silicon core that a kind of inwall silicon core layer is uniformly dispersed, lubricity is good tube preparation method for the existing above-mentioned deficiency of existing silicon core pipe.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of preparation method of silicon core pipe, it is characterized in that in silicon core pipe production process, internal layer starting material are except traditional dispersion agent amine hydroxybenzene that adds certain weight ratio when adding silicon core tube mother material and matrix resin HDPE, dispersion aids glyceryl monostearate, processing aid oligopolymer, processing aid white oil, wherein dispersion agent amine hydroxybenzene, dispersion aids glyceryl monostearate, processing aid oligopolymer, the weight ratio of processing aid white oil is: dispersion agent amine hydroxybenzene/dispersion aids glyceryl monostearate/processing aid oligopolymer/processing aid white oil=1/1/2.5/2.5.
In a preferred embodiment of the invention, described oligopolymer is selected from polyureas, polycarbonate, polyester or the polymeric amide that number-average molecular weight is less than 10000.
The invention has the beneficial effects as follows: the present invention changes traditional silicon sandwich layer masterbatch proportioning, the compound auxiliary agent that adds makes silicon core layer masterbatch be uniformly dispersed at internal layer, without gathering, has significantly promoted the lubricity of silicon core inside pipe wall.Because composite assistant cost is lower than silicon core masterbatch, also reduced the production cost of enterprise simultaneously.
