Description
Technical field
The present invention relates to 3D printing technique field, more particularly to a kind of method of 3D printing construction material.
Background technology
At present, in 3D printing construction material, 3D printer built with it is for building can jointing material, after being connected with computer,
By the multilayer printing type of layer upon layer, the blueprint on computer is finally become in kind.3D printing technique, which is applied, is building
When building in industry, after computer design draws relevant building pattern, the motion of X-direction is realized by portal frame walking mechanism；
The motion of Y direction is realized by crossbeam；The motion of Z-direction is realized by the print bar on printhead top.By printhead itself
Flexible and rotation, the local motion of printing head is realized, it is raw so as to pass through the continuous accumulation of " plane layer " that prints building
Into different building structure.Wherein, 3D printer shower nozzle spray it is for building can binding material, exist adhesion strength difference ask
Topic, it would be highly desirable to solve.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of method of 3D printing construction material, not only
Raw material sources are extensive, and can effectively solve a large amount of urban building wastes and huddle to leave about, at the same can effectively save resource, meet 3D
The needs of printing, because intensity is high, good endurance, therefore can significantly mitigate structure design weight, save construction material and the energy
Consumption, can be quickly to realize that industrial production building intellectualization supports.
A kind of method of 3D printing construction material proposed by the present invention, comprises the following steps：
S1, building waste crushed, ground, added iron tailings, magnesia oxychloride cement, filler, cobalt naphthenate and stir
Obtain mixed material；
S2, add into mixed material Bisphenol a unsaturated polyester resin, water reducer, sodium carboxymethylcellulose, when opening
Between conditioning agent stir, be subsequently added into water and stir, be then transferred in 3D printing system printing and obtain construction material.
Preferably, in S1, building waste, iron tailings, magnesia oxychloride cement, filler, the weight ratio of cobalt naphthenate are 40-
80：35-45：20-40：35-45：1-2.
Preferably, in S1, filler includes by weight：Glass microballoon 5-12 parts, quartz sand 4-10 parts, alkaline residue 5-15
Part, gypsum 10-20 parts.
Preferably, in S2, mixed material, Bisphenol a unsaturated polyester resin, water reducer, sodium carboxymethylcellulose, opening
Time adjustment agent, the weight ratio of water are 160-170：5-12：1-2：2-4：0.5-1：30-50.
It can perfectly be combined between each layer of the present invention, after natural curing, preferable toughness and intensity, institute can be obtained
Obtaining construction material also has preferable mobility, is adapted to pumping and lifting, during 3D printing, can quickly be formed and envision knot
Structure, caking ability are high, and it is obvious that building finished product is less prone to lamination, building Stability Analysis of Structures itself.
After the present invention crushes building waste, with iron tailings, magnesia oxychloride cement, glass microballoon, quartz sand, alkaline residue, gypsum
Compounding, not only raw material sources are extensive, and can effectively solve a large amount of urban building wastes and huddle to leave about, and building waste circulated past
It is multiple to utilize, be really achieved the purpose of no pollution discharge, while can effectively save resource, meet the needs of 3D printing, its integrate into
This low cost, material source is extensive, large dosage building waste, because intensity is high, good endurance, therefore can significantly mitigate structure and set
Weight calculation amount, construction material and energy resource consumption are saved, can be quickly to realize that industrial production building intellectualization supports.
The present invention is by test, and its antidetonation, shock resistance are good, and its 3 days intensity are not less than 78MPa, and rupture strength is not low
In 16Mpa, play mould and be not less than 38Gpa；28 days intensity is not less than 126Mpa, and rupture strength is not less than 21Mpa, plays mould and is not less than
58Gpa；Printed material using is processed as powder packaging, site operation directly add water stirring 1-2min after it is i.e. pumpable, apply
It is short between man-hour, quickly, it is adapted to site operation printing prefabricated component.
