Description
Technical field
The invention belongs to pipeline material fields, are related to field of polymer composite material, and in particular to a kind of intermediate water pipeline base
The preparation method of material.
Background technique
Pipeline refers to be used to convey gas, liquid or with solid with what pipe, pipe connector and valve etc. were connected into
The device of the fluid of grain.Having many uses for pipeline is general, is used primarily in water supply, draining, heat supply, gives gas, long distance delivery petroleum
In natural gas, agricultural irrigation, hydraulic engineering and various commercial plants.Present intermediate water pipeline uses PVC sewer pipe more,
When preparation, in order to promote the corrosion resistance of material, often also need using preceding in inner wall of the pipe or external coating anticorrosion
Layer, causes higher cost, and the adhesion of the stability and coating and pipeline material to coating has very high requirement.
Summary of the invention
The object of the present invention is to provide a kind of corrosion-resisting compound pipes to improve pipe by improving to raw pipeline material
The corrosion resistance in road, and it is raw material that is at low cost, being easy to get that raw material, which is added, and the cost of production can also be effectively reduced.
The invention is realized by the following technical scheme:
A kind of preparation method of intermediate water pipeline substrate, comprising the following steps:

Type；
The weight ratio of each raw material is as follows: polyvinyl chloride resin 70-82%, PP resin 5-10%, basalt fibre 2-5%, attapulgite 7-
10%；
The attapulgite passes through modification, and modification procedure is as follows:
(1), attapulgite is weighed, using the sulfuric acid treatment 20-25min of 1.5mol/L, is then washed to neutrality；It (2), will step
Suddenly the attapulgite that (1) is handled well uses the acetone soln immersion treatment 10-12min of volume fraction 10%, uses in soaking process
Ultrasonic oscillation processing, ultrasonic frequency 25kHz, then drying to constant weight at 65-70 DEG C；
(3), the attapulgite that step (2) is handled well is put into treatment fluid and is handled, in treatment process, first use ultrasonic wave
20min is handled, then handles 2h using magnetic agitation, during magnetic agitation, intermittent warming is carried out within the scope of -4-75 DEG C,
Then it filters, the treatment fluid is made of following component by weight: 2.4 parts of calgon, 1.25 parts of ester based quaternary ammonium salt, hard
2.2 parts of fatty acid magnesium, 1.5 parts of nano zine oxide, 1 part of dioctyl phthalate, 20 parts of ethyl alcohol of volume fraction 65%；
(4), the attapulgite and silane coupling agent KH560 handled step (3) well are mixed by weight the ratio of 100:2.2
Afterwards, 20min is first stirred under 2000r/min revolving speed using high-speed mixer, microwave treatment 1-2min is then used, in 38-42
15-20min is handled at DEG C, is obtained attapulgite modified.
Attapulgite can be made preferably to contact with silane coupling agent using microwave treatment, and pass through microwave treatment, step
Suddenly the nano zine oxide in (3) in conjunction with attapulgite can also be generated with silane coupling agent and be contacted, and make nano zine oxide can be with
It is dispersed in attapulgite's surface, is conducive to contact with other raw materials, disperse, promote the stable of chemical bond, can also promote material
Corrosion resistance.
By carrying out pickling, organic solvent processing and drying to attapulgite's surface, it is micro- attapulgite's surface can be improved
The activity in hole, is then handled using treatment fluid, so that the activity of attapulgite's surface is stronger, is able to ascend and resin material
The effect dispersed with basalt fibre, and pass through coupling agent treatment, it can increase the stress such as attapulgite and resin after compound
Tie point promotes the intensity of connection.
In attapulgite modified processing, intermittent warming mode is as follows during magnetic agitation: first handling at -4 DEG C
10min then heats to 20 DEG C of processing 10min, is warming up to 45 DEG C of processing 5min, is warming up to 60 DEG C of processing 10min, is warming up to 75
DEG C processing 15min, is then cooled to 4 DEG C of processing 15min, then be warming up to 25 DEG C to terminate to intermittent warming.Attapulgite modified
In the process, by intermittent warming, the hole of attapulgite's surface is enabled to have certain contraction or diastole, treatment fluid is preferably
It is dispersed in the micropore of attapulgite's surface, promotes modified effect, and after addition, make material in contact soda acid equal solvent
When, molecule interchain has certain slipping space, not will cause molecular chain rupture, influences the performance of product.
The microwave treatment power is 400W.
The basalt fibre is handled using following methods, a, 30 parts of ethyl alcohol, the water for taking volume fraction 75% by weight
20 parts, 0.8 part of 2 parts of glacial acetic acid, silane coupling agent mixing 20min, are made solution；B, basalt fibre is used into quality point
The sulfuric acid solution immersion treatment 5-6min of number 18%, is then washed, and washes away the acid solution on surface, drying；C, step b is handled well
The solution immersion treatment 2-3h that basalt fibre is prepared using step a, then cleans, dries at 50-60 DEG C, obtain basalt
Fiber.Basalt fibre is handled using acid solution, on the one hand can remove the ingredients such as the impurity on surface, it on the other hand, can be with
Slight etching trace is formed on basalt fibre surface, promotes the surface area of basalt fibre, due to only in basalt fibre
Dimension table face forms more slight etching trace, and apparent negative effect can't be generated to its mechanical property, meanwhile, it can increase
Treatment fluid can be obviously improved coupling agent in the dispersing contact on basalt fibre surface in the attachment point on basalt fibre surface,
In basalt fibre and resin compounded, increase stress tie point, stress is enable to be dispersed, compound rear material can be promoted
Intensity can also promote wearability.
The silane coupling agent is Silane coupling agent KH550.
The extruder first segment temperature is 110-120 DEG C, and second segment temperature is 140-150 DEG C, and third section temperature is
155-167 DEG C, head temperature is 175-185 DEG C.
The draw ratio of extruder is 20:1.
PVC number-average molecular weight is 85000-87000 in the application, and PP number-average molecular weight is 42000-45000.
Although the pipeline of the application preparation has enough anti-corrosion ability, can also be applied in pipe surface using preceding
Bitumen layer is covered, anti-corrosion effect is further promoted.
Beneficial effects of the present invention: wearability composite pipe material provided by the present application is multiple using polyvinyl chloride resin and PP resin
Cooperation is resin matrix, and PP can improve the crystal property of polyvinyl chloride resin, basalt fibre and attapulgite modified is added, utilization is profound
The effect of military rock fiber and attapulgite as skeleton and crosslinking points promotes the humidification to resin, can be obviously improved pipeline
Magnesium stearate, dioctyl phthalate, tool is added in the mechanical property and wear-resisting property of finished product during attapulgite modified
There are the anti-aging property and corrosion resistance for being able to ascend material, attapulgite can significantly reduce auxiliary agent in use again
It is lost, promotes the safety during materials'use, reduce the pollution to environment.Moreover, material source used herein
Extensively, relative inexpensiveness, very big pollution will not be generated in treatment process to environment, and effect is obvious.
Due to the porous suction-operated of attapulgite, when material after shaping is by external force, attapulgite and resin by
In stronger interface connection function, reduce the probability of joint face fracture, moreover, because joined basalt fibre during the preparation process
Dimension, basalt fibre and attapulgite can form the structure of jack, can in stress dispersive stress, and have strand
Certain extendable room, and then it is obviously improved the wear-resisting of compound system, corrosion resistance and mechanical property.
