Scuffing is easily caused, because ground motion can also wear and tear to tubing after laying, causes wall thickness thinning, the long-term stress of tubing
Inequality is so as to cause fray to occur booster, it is necessary to which its wearability is improved.
The content of the invention
It is an object of the invention to provide a kind of wear resistant polyethylene composite pipe, the easy of conventional polyethylene tubing presence is solved
Abrasion, the problem of easily scratch, the characteristics of with rub resistance, shock resistance, smooth surface, the effective guarantee safety of pipe-line system and
Service life.
Wear resistant polyethylene composite pipe of the present invention, is prepared from the following raw materials in parts by weight：
Wherein：
Described coupling agent is silane coupler KH570, and the molybdenum disulfide through coupling agent treatment belongs to people in the art
The normal operation of member.
The preparation method of described wear resistant polyethylene composite pipe comprises the following steps：
(1) batch mixing：
HDPE, molybdenum disulfide, nano ceramic powder, superfine carbon black, polytetrafluoroethylene (PTFE) and calcium stearate is mixed by high speed
Conjunction machine is mixed, and removes moisture contained therein by frictional heat, obtains dispersed mixed material；
(2) extruder is extruded：
Mixed material feeds extruder, compressed, melting and homogenizing by hopper, under external heat and screw rod shearing effect,
It is changed stepwise by powdery solid as high viscoelastic body, and it is continuous through head extrusion；Wherein, the heating-up temperature of extruder barrel is 1
Area：100 DEG C, 2-6 areas：200℃；
(3) mould vacuum forming：
High viscoelastic body is changed into linear motion from rotary motion by filter and enters pipe mold, by shunting muscle after by
Step is fused to tubular-type embryo in profiled section；Wherein, the mold temperature in 1-5 areas is 200 DEG C, and mouth mold is 210 DEG C.
(4) cooling and shaping：
Tubular-type embryo enters cooling diameter-setting equipment, and its temperature is gradually reduced, untill room temperature is dropped to, and pipe embryo is protected all the time
Demonstrate,prove fixed sizing in the case of outer shape；
(5) traction cutting：
Molded tubing is equably moved forward in the presence of draw-gear, by rotating fly-bar formula cutting machine come complete
Into the customized cut-off of tubing, and make section smooth.
The key technology of the present invention is to be modified research to high density polyethylene (HDPE) (HDPE), to improve HDPE tubing
Wearability and processability：
(1) wear-resisting study on the modification
The present invention by added into HDPE molybdenum disulfide Jing Guo coupling agent treatment, superfine carbon black, nano ceramic powder,
The inorganic fillers such as polytetrafluoroethylene (PTFE) (abrasion resistance modifier), reduce the coefficient of friction of tubing, improve wearability, play anti-attrition,
Wear-resisting effect, moreover it is possible to which creep properties, bending strength, rigidity, hardness, thermal flexibility, heat distortion temperature and the size for improving HDPE are steady
It is qualitative etc., it is improved HDPE combination property；
(2) processing characteristics study on the modification
In order to prevent the hydraulic performance decline for adding HDPE after modifying agent, appropriate nucleator, such as wollastonite, benzene first can be added
The method of acid, benzoate, stearate, adipate etc. effectively prevents the decline of HDPE mechanical strengths, it is ensured that after blending
The processing fluidity increase of material, and the performances such as tensile strength, bending elasticity, impact strength and the rub resistance of material are not reduced.
Beneficial effects of the present invention are as follows：
The present invention on the premise of other performances of tubing are not influenceed, is improved by adding abrasion resistance modifier into HDPE
The wearability of HDPE tubing, improves HDPE mobile performance, it is more easy to processing and forming, and the tube surfaces produced are also more
It is bright smooth, it is more suitable for conveying solid-liquid mixtures, while can avoid that causes in handling, transport and installation process from drawing
Wound, especially minor caliber pipe, effectively ensure the safety and service life of pipe-line system.
