Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Please refer to Fig.2, the embodiment of the present invention provides a kind of guardrail base preparation method, including step：S1：Using macromolecule
Material is raw material 3D printing guardrail base substrate；
S2：Prepare guardrail base filler material；
S3：The guardrail base filler material is placed in the guardrail base substrate, in the guardrail base filler material
Outside uses high molecular material as raw material 3D printing guardrail base shell.
As shown in Figure 1, printing guardrail base 1 by 3D printing technique first in the present embodiment, will then prepare
Guardrail base filler material 2 be placed in guardrail base substrate 1, pass through 3D printing technique again in the periphery of guardrail base filler material 2
Shell 3 is printed, operating procedure is convenient and simple.
Further, the high molecular material for ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-
Butadiene-styrene), PVA (polyvinyl alcohol, vinylalcohol polymer, polyvinyl alcohol), PLA
One or more in (polylactic acid, polylactic acid).This implementation is by 3D printing technique using high molecular material as raw material
The printing of guardrail base is carried out, 3D printing technique is applied to the field of traffic guardrail base preparation, high-volume is coped with and protects
The preparation of column base, and cost is relatively low, easy to operate, science and technology environmental protection.
Further, described " preparing guardrail base filler material " specifically includes following steps：
S21：Initial feed is cleaned, desalination, denitrogenate, dry, ball-milling treatment formed aluminium ash filling material, it is described just
Beginning raw material is mainly made of the component of following mass fraction：0-5 parts of pure aluminum, 20-40 parts of aluminium oxide, 10-30 parts of aluminium nitride；
S22：The aluminium ash filling material is uniformly mixed with auxiliary material；
S23：Above-mentioned mixed material is subjected to static pressure processing, forms guardrail base filler material blank；
S24：The guardrail base filler material blank is subjected to high-temperature steam curing and forms guardrail base filler material.
In the present embodiment using aluminium ash eventually material as initial feed carry out guardrail base filler material system, aluminium ash eventually expect in into
Divide species more, predominantly pure aluminum, aluminium oxide, aluminium nitride, it is also possible to standby to expect to carry out again eventually by aluminium ash including some fluorides
Utilize, the cost of guardrail base making can be saved, while reach refuse reclamation.Initial feed is cleaned first, is removed
Salt, denitrogenate, dry, ball-milling treatment formation aluminium ash filling material, raw material of the granularity between 10-200 mesh is ultimately formed, by upper
The step of stating controls the granularity of raw material within range above so that obtained aluminium ash filling material granularity is thinner, rear
The guardrail base filler material prepared in continuous step is more convenient, and structure is more preferable.
Further, the removal of impurities, which is handled, is specially：The initial feed is immersed in the water, 10- is stood after stirring
30min, removes upper strata floating material, takes out bottom and is insoluble in the first sediment of water, and the volume ratio of the initial feed and water is
1:1.Material impurity is more eventually for aluminium ash as initial feed, carries out removal of impurities processing first, is about 1 using solid-liquid volume ratio:1 water
First step removal of impurities is carried out, soaking the shorter time first removes impurity therein.
Further, it is described except salt treatment is specially：First sediment is immersed in the water, solid-liquid volume ratio is 1:5-
1:10,2-3h is stood after stirring, then removes the upper solution of 40%-70%, takes out remaining liq and the second sediment.
It is subsequent that except salt treatment is soaked the first sediment after removal of impurities, the dopant species during aluminium ash is expected eventually are more,
It is mainly fluoride salt, chlorate etc. of the aluminium ash eventually in material in the solution of immersion.
Further, it is described to denitrogenate processing and be specially：High temperature is carried out to the remaining liq and second sediment to remove
Nitrogen 1-2h, obtains the 3rd sediment, and the high temperature denitrogenates temperature as 100-120 DEG C.
Then the second sediment and remaining liq are carried out denitrogenating processing, denitrogenated broken using ultrasonic wave stirring in processing procedure
Broken mode crushes second sediment, carries out broken by the second sediment so that sediment granularity diminishes, denitrogenates
Processing is faster and more thorough.
Further, the drying and processing is：3rd sediment is put into 100-150 DEG C of baking oven and is dried
3-6h.Drying and processing then is carried out to the 3rd sediment, the sediment after drying can just polish, granularity is diminished, is easy to
The preparation of follow-up aluminium ash filling material, the granularity after polishing in the present embodiment are controlled between 10-200 mesh, and raw material are mutually mixed
Conjunction is then suppressed, by granularity control it is smaller various raw material can be facilitated to be mutually mixed uniformly, and be easy to follow-up pressure
Step processed.
Further, described " being uniformly mixed the aluminium ash filling material with auxiliary material " is specially：
The each component of following mass parts is mixed：45-60 parts of aluminium ash filling material, 5-10 parts of quick lime, white lime
8-12 parts, 3-5 parts of gypsum, 10-20 parts of cement, 2-5 parts of SILICA FUME, 5-10 parts of engineering sand, 0.09-0.24 parts of high energy water-reducing agent,
0.18-0.36 parts of Rocky sand crystal, 0.09-0.24 parts of calcium formate, 6-13 parts of water.
A series of aluminium ash filling material obtained after processing is mixed with other auxiliary materials of each component, using mechanical agitation
Mode stir evenly the preparation for carrying out guardrail base filler material, raw material after stirring is into static pressure processing is crossed, 15-20MPa's
Constant pressure 5-10min under pressure so that the guardrail base filler material stable structure of preparation.By raw material are mixed in this present embodiment
After be pressed to form guardrail base filler material, in order to enable the filler material after shaping is more firm and increase guardrail bottom
Seat filler material shaping speed, has selected in the present embodiment mixing material quick lime and white lime to carry out the system of guardrail base filler material
It is standby；The addition of the calcium formate of certain component can speed up the speed that each component mutually solidifies, and improve production efficiency.
Further, the high-temperature steam curing is specially that the guardrail base filler material blank is placed on 60 DEG C -80 DEG C
Steam-cured 6-12h in water vapor atmosphere.Guardrail base filler material blank is formed after static pressure processing stripping forming, which is filled out
Charge blank be placed in the water vapor atmosphere of certain temperature carry out it is steam-cured so that stable structure in the blank, above-mentioned high temperature steam
Foster step can also be carried out by the way of naturally steam-cured, and guardrail base filler material blank is placed in natural environment and is carried out
Maintenance also can reach same effect, but need longer time.
The application expects to carry out the preparation of guardrail base, the grey material eventually of aluminium is recycled, Neng Goujie eventually by using aluminium ash
The cost that guardrail base makes is saved, in combination with 3D printing technique so that the preparation process of guardrail base is more simple and convenient, together
When may also reach up refuse reclamation and energy-saving and environment-friendly purpose.
Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.People in the art
Member should be appreciated that invention scope involved in the application, however it is not limited to the technology that the particular combination of above-mentioned technical characteristic forms
Scheme, while should also cover in the case where not departing from the inventive concept, carried out by above-mentioned technical characteristic or its equivalent feature
