Description
Technical field
The present invention relates to 3D printing technique field more particularly to a kind of high bond strength 3D printing mortars.
Background technology
Reach preferable 3D printing effect, needed to have on self property for the mortar that 3D printing is built defeated
After sending pipe, curing rate is fast, caking ability is high, and so as to obtain larger intensity, but the adhesion strength of current building mortar is poor,
Poor plasticity, the concrete generally used in architectural engineering do not have the property that can be used for 3D printing.
The content of the invention
Technical problems based on background technology, the present invention propose a kind of high bond strength 3D printing mortar, not only
Convenient material drawing and cheap, realizes the reasonable utilization of resource, and product is made to play an important role of to keep mortar plasticity, solves
The bleeding problem that weathered coal, bentonite are easy to cause as raw material, while ensure that its mobility and cohesive force.
A kind of high bond strength 3D printing mortar proposed by the present invention, raw material include by weight：Normal silicate water
50-65 parts of mud, 60-80 parts of weathered coal, 15-24 parts of bentonite, 8-14 parts of mica powder, 10-16 parts of zeolite powder, flax fiber 4-10
Part, 2-6 parts of calcium sulfate crystal whiskers, 4-8 parts of pitch micro mist, 1-3 parts of sodium carbonate, 0.5-1.5 parts of water-reducing agent, 0.8-1.6 parts of soft white sugar,
0.1-0.8 parts of air entraining agent, 0.5-1.45 parts of sodium carboxymethylcellulose.
Preferably, weathered coal, bentonite, mica powder, the weight ratio of zeolite powder are 70-74：18-22：10-12：11-14.
Preferably, flax fiber, the weight ratio of calcium sulfate crystal whiskers are 6-8：3-5.
Preferably, Portland cement, the weight ratio of sodium carboxymethylcellulose are 56-60：0.8-1.
Preferably, pitch micro mist, the weight ratio of sodium carbonate are 5-7：1.5-2.
The present invention can improve the rheology characteristic of conventional cement material so that it is with the strong moulding self-supporting of class clay
Can, Components Shape after its natural hydration and sclerosis is retained, effectively shortens product and add by the finished product good moldability after 3D printing
The time of work avoids the waste of material, improves production efficiency, and the strength of materials is high, stability is good, deformation is small, can be random
Prepare the structure of any shape.
The present invention is coordinated using weathered coal, bentonite, mica powder, zeolite powder and flax fiber, calcium sulfate crystal whiskers, is not only taken
Material is convenient and cheap, realizes the reasonable utilization of resource, and product is made to play an important role of to keep mortar plasticity, solves
The bleeding problem that weathered coal, bentonite are easy to cause as raw material, while ensure that its mobility and cohesive force.
Compared with prior art, the present invention has works fine performance, constructability energy, mechanical property, setting time
Within 15min, plasticity is fabulous, is molded suitable for printing speed, and product strength is high, 28d compression strength reach 53MPa with
On, limiting strain 0.74-0.76%, tensile strength 7.2-8.6MPa.
