Abstract
The present invention relates to a kind of preparation processes of high impact properties anti-corrosion lightweight PE solid wall pipe.Using intercalation nano montmorillonite technology, then cooperate bisphenol A type epoxy resin, so that the crosslinking curing between formula system forms a fine and close entirety, so that PE solid wall pipe deformability with higher, impact strength, tensile strength and toughness are improved；Sericite in powder microstructure is flake, flakey or plate, it is big with radius-thickness ratio, hardness is high, with be dispersed in high-density polyethylene resin, it can play the role of rigid backbone, improve the ring stiffness of tubing, sericite in powder also has good conductive insulating properties, anti-flammability simultaneously, so that solid wall pipe has good anti-electrostatic fire retardant effect, high-density polyethylene resin is filled while enhancing is played and improves the mechanical properties such as tensile strength, bending strength using sericite in powder and also reduces cost；Preparation method is simply scientific, low in cost, preparation process environmental protection, will not generate pollution to environment.
Description
Technical field
The invention belongs to plastic pipe fabricating technology fields, are related to a kind of high impact properties anti-corrosion lightweight PE solid wall pipe
Preparation process.
Background technique
Hollow spiral tube be it is a kind of with high density polyethylene (HDPE) (HDPE) for raw material, be made of hot winding shaping process
Structure-wall pipe material, have that flexibility strong, inner wall smooth, flow resistance be small, wear-resisting and corrosion resistant performance, there is excellent Gao Gang
Degree, high-intensitive, light-weight, impact resistance be strong, not cracky the features such as, be suitable for conveying water temperature and arranged in 45 DEG C of municipal administrations below
Water, building outdoor drainage, the defeated draining in buried farmland, discharge of industrial wastes, road drainage, sewage and waste water drainage system, sports ground and
Plaza Project draining and electrical telecommunication engineering etc..
Plastic pipe is insulating materials, has good electrical insulation capability, but its surface is extremely easy to produce static electricity.Industry is raw
The dust suspension and the mutual frictional impact in hollow spiral tube surface in environment are produced, positive and negative charge redistribution is gathered in respectively
In hollow wall tube surfaces and dust；And these electrostatic charges are difficult to migrate, when static charge buildup will discharge production to a certain extent
It lights a fire flower, brings security risk, fire or chemicals is caused to explode.
The existing usual mechanical property of PE solid wall pipe is bad, does not have excellent impact resistance, shock resistance degree, corrosion resistance
With heat-resistant antifriction performance, preparation process is at high cost.
Summary of the invention
The purpose of invention: the present invention provides a kind of preparation process of high impact properties anti-corrosion lightweight PE solid wall pipe, techniques
Simple science, low in cost, PE solid wall pipe impact resistance obtained greatly improves, and antiseptic property is excellent.
Technical solution: in order to achieve the goal above, the invention discloses a kind of high impact properties anti-corrosion lightweight PE solid wall pipes
Preparation process, comprising the following steps:
(1) score meter by weight, weigh respectively 60-80 parts of high density polyethylene (HDPE), 20-30 parts of linear low density polyethylene,
30-50 parts of bisphenol A type epoxy resin, 80-120 parts of sericite in powder, 5-15 parts of organic nano imvite, aluminium-doped zinc oxide 6-8
Part, 1-3 parts of epoxy polyethylene wax, 1-3 parts of coupling agent, 6-12 parts of impact modifier, 0.5-1.5 parts of antioxidant, stabilizer 2-4
Part；
(2) using high density polyethylene (HDPE) as matrix, sericite in powder is as filler material at a temperature of 160-180 DEG C and 6-8kg
Melt index under loading condiction is that high density polyethylene (HDPE) reinforcing material is prepared in 0.05-0.2g/10min；
(3) organic nano imvite and bisphenol A type epoxy resin are mixed according to the proportion, 20-30 parts of acetone and 10- is added
The mixed solution of 15 parts of toluene, the ultrasonic disperse 2-3h in ultrasonic instrument, then again under the conditions of 65-95 DEG C of temperature stirring carry out it is slotting
It is spare to obtain intercalation object for layer reaction 1-3h, excessively 500 meshes；
(4) by intercalation object made from high density polyethylene (HDPE) reinforcing material made from step (2), step (3), linear low
Density polyethylene, aluminium-doped zinc oxide, epoxy polyethylene wax, coupling agent, pest-resistant modifying agent, antioxidant, stabilizer are added together
3-4min is mixed under the conditions of revolving speed 600-800r/min, 85-100 DEG C of temperature into high mixer and obtains PE composite material；
(5) above-mentioned PE composite material pressurization plasticizing is added twin-screw extrude to squeeze out to obtain pipe in molten condition,
It is cooled and shaped the solid-wall pipe for various specifications through calibration sleeve again, then forms the PE solid wall pipe through traction cutting.
Preferably, the organic nano imvite is 50 parts of nano montmorillonites and 10-50 parts of cetyl trimethyl chlorinations
The aqueous solution ion exchange that ammonium carries out 4-8h under the conditions of 60-70 DEG C of temperature organises after reaction successively through filtering, and ethyl alcohol and goes
Ionized water is washed according to the mixed liquor that volume ratio 1:1 is formed, then is dried in vacuo under the conditions of 70-100 DEG C, be crushed 300-
500 meshes obtain.Using intercalation nano montmorillonite technology, then cooperate bisphenol A type epoxy resin, so that the crosslinking between formula system
It is formed by curing a fine and close entirety, so that PE solid wall pipe deformability with higher, impact strength, tensile strength and toughness
It is improved.
Preferably, the bisphenol A type epoxy resin is the one or two of commercialization E12, E51.
Preferably, the coupling agent is butyl titanate coupling agent.It buys in occasion auxiliary chemicals oil plant factory of Tianzhang City day, it should
Product easily with-NH3 ,-OH ,-COOH, the reaction of-CONH2 isopolarity group, especially easily occurs hydrolysis with water, can mention
