Abstract
The invention discloses a pipe product with high smooth finish and a production method thereof, pertaining to the technical field of the pipe product manufacturing. The pipe product comprises ingredients with the following weight ratio: 94 percent to 96 percent of TR480PE base, 2 percent to 4 percent of black master batch and 1 percent to 3 percent of fluoropolymer additive. The production method of the invention comprises the steps that (1) prepared raw materials are evenly blended by a vertical mixer and then granulated by a granulator; (2) the granulated materials are dried by a dryer; (3) the dried raw materials are then added into an extruder to be processed into a formed pipe product. The produced PE pipe product has less scratches and good finish on the surface and is comparatively bright by visual inspection, which solves the problem of the surface quality of the pipe product to a certain extent, eliminates material deposits from the mouth mould and improves the productivity effect.
Description
Technical field
The invention belongs to the tubing manufacture technology field, be specifically related to a kind of tubing and production method thereof of best bright finish.
Background technology
Under the guidance of country's " to mould Dai Gang " policy, plastic conduit has obtained applying widely, and along with improving constantly of people's understanding, not only the life-time service performance of plastic conduit is concerned about, and the visual appearance of plastic conduit also receives much concern.The PE material is lower owing to melting finger, and difficulty of processing is big, and the tubing that processes often causes cut because of mouth mould buildup, and surface smoothness is relatively poor, can not satisfy the visual appearance demand of client to tubing well.
Summary of the invention
At the above-mentioned problems in the prior art, the object of the invention is to provide the technical scheme of a kind of best bright finish tubing and production method thereof.
The tubing of described a kind of best bright finish, the proportioning raw materials that it is characterized in that constituting this tubing is the additive 1-3% of TR480PE base-material 94-96%, black masterbatch 2-4%, fluoropolymer.
The tubing of described a kind of best bright finish, the proportioning raw materials that it is characterized in that constituting this tubing is the additive 1.5-2.5% of TR480PE base-material 94.5-95.5%, black masterbatch 2.5-3.5%, fluoropolymer.
The tubing of described a kind of best bright finish, the proportioning raw materials that it is characterized in that constituting this tubing is the additive 2% of TR480PE base-material 95%, black masterbatch 3%, fluoropolymer.
The production method of described a kind of best bright finish tubing is characterized in that comprising following processing step:
1) raw material for preparing is passed through the vertical stirrer uniform mixing, again by the tablets press granulation;
2) the granulation material is passed through the dehumidifying heat pump drying;
3) dried raw material is added forcing machine machine-shaping tubing.
The production method of described a kind of best bright finish tubing is characterized in that step 2) in moisture content be lower than 300mg/kg.
The PE tube surfaces cut of above-mentioned production is less, and surface smoothness is good, and the tubing that is observed visually is light relatively, has solved the quality problems of tube surfaces to a certain extent, and has eliminated a mouthful mould buildup, has improved production efficiency.
Embodiment
The invention will be further described below by embodiment.
A kind of tubing of best bright finish, the proportioning raw materials that constitutes this tubing are the additive 1-3% of TR480PE base-material 94-96%, black masterbatch 2-4%, fluoropolymer; Constitute the additive 1.5-2.5% that the preferred proportioning raw materials of this tubing is TR480PE base-material 94.5-95.5%, black masterbatch 2.5-3.5%, fluoropolymer; Constitute the additive 2% that the only proportioning raw materials of this tubing is TR480PE base-material 95%, black masterbatch 3%, fluoropolymer.
A kind of production method of best bright finish tubing comprises following processing step: 1) raw material for preparing is passed through the vertical stirrer uniform mixing, again by the tablets press granulation; 2) the granulation material is passed through the dehumidifying heat pump drying, and guarantee that moisture content is lower than 300mg/kg; 3) dried raw material is added forcing machine machine-shaping tubing.
Claims (5)
