Description
Technical field
The present invention relates to a kind of thermal insulation concrete canvas and preparation method thereof, more specifically to a kind of phase-change accumulation energy
Three dimensional fabric concrete canvas and preparation method thereof.
Background technology
When the emergencies such as natural calamity or war occur, human needs rely on temporary tent as sanctuary, and show
It is mostly that canvas is built to have temporary tent, is not kept the temperature, and security performance is low, no image of Buddha concrete construction equally provide safely, have
The protection of effect.The design philosophy of concrete canvas is to be proposed by two British Students Brewin and Crawford for 2004 earliest,
They have found when British troops are on active service, and on disaster area or region of war, all there is an urgent need to a kind of energy fast constructions for aid agency and army
The method of building for temporary habitation, then they devise it is a kind of interim protect tent, i.e., cement powder is filled into three dimensional fabric, then
It is layered on the air bag of tent size, finally sprinkling water in fabric surface is molded.Now, concrete canvas is making account
Practical application is had been obtained in the engineerings such as paulin, military engineering, ditch lining, slope protection prevention, pipe protection, roof guard.
In order to further increase the heat-insulating property of concrete canvas, determine phase-change material and cement injection material proportioning it
Afterwards, it is filled into three dimensional fabric, makes phase-change accumulation energy three dimensional fabric concrete canvas.By phase-change accumulation energy three dimensional fabric concrete
The tent of canvas processing compared with plain sail tent there is heat preservation, energy saving, condensation to harden rapid, fire-retardant, waterproof, windproof etc.
Characteristic.
Composite phase-change material PX 25 is selected, itself and quick-hardening cement mortar grouting material are blended, injection three dimensional separation is knitted
In object, phase-change accumulation energy three dimensional fabric concrete canvas is prepared.
Invention content
The present invention solve the problems, such as existing plain sail tent with it is insufficient, a kind of phase-change accumulation energy three-dimensional is provided and is knitted
Object concrete canvas, the canvas have the performances such as rapid, fire-retardant heat preservation, condensation hardening, waterproof, windproof, meet fast construction and face
When requirement of the tent as sanctuary.
Simultaneously the present invention also provides the preparation method of the concrete canvas, preparation method is simple, at low cost.
The present invention is achieved by the following technical solutions：
The phase-change accumulation energy three dimensional fabric concrete canvas of the present invention, is made of three-dimensional spacer fabric and cement injection material,
In, the three-dimensional spacer fabric is glass fibre warp knit three-dimensional spacer fabric, and thickness is 20~30mm；The cement injection
Material is by quick-hardening cement, and quartz sand, phase-change material forms, on the basis of 100 parts of cement injection material, quick-hardening cement in cement injection material
Dosage be 35~45 parts, quartz sand dosage be 45~60 parts, phase-change material dosage be 2~10 parts, when used quick-hardening cement,
Quartz sand and phase-change material, which are uniformly mixed, can be used.
The phase-change accumulation energy three dimensional fabric concrete canvas of the present invention, further technical solution are the quartz sand
Fineness modulus is 2.3-3.7.
The thermal insulation concrete canvas of the present invention, further technical solution can also be that the phase-change material is PX
25。
The thermal insulation concrete canvas of the present invention, further technical solution can also be that the cement is 52.5 aluminum sulfate
Salt cement.
The preparation method of the thermal insulation concrete canvas of the present invention comprising following steps：
Quick-hardening cement, quartz sand, phase-change material are added in cement plaster blender, stirring at low speed is after 60 seconds, then high
The cement injection material of formation is poured into three-dimensional spacer fabric in 60 seconds by speed stirring.
Compared with prior art the invention has the advantages that：
The present invention ensure that early stage is quickly hard due to having the characteristics that fast hydration forms intensity using aluminum sulfate salt cement
Change, a variety of excellent properties such as late expansion stabilization further improve heat-insulating property due to being added to phase-change material.In addition it forms
The each component raw material of cement injection material of the present invention is easy to get, 25 phase-change material steady sources of PX, moderate.
The product grout material of the present invention is perfused with good, and sulfate cement has the characteristics that rapid hardening high-strength, condensation
Time is less than 1.5 hours, and 7 days compression strength can reach 30MPa, and flexural strength reaches 15MPa, apparent density 1.5-2.0g/
cm3, thermal coefficient 0.18-0.48W*m-1*k-1, much smaller than the concrete canvas 1.3W*m for not mixing phase-change material-1*k-1.It is suitable for
Under low temperature or normal temperature condition, demand that all kinds of temporary tents are built.
The preparation method of the present invention simultaneously, it is simple for process.
