The ratio of powder containing common brick about 50%-55% in the regenerative powder, the about 45%- of ratio containing concrete powder
50%, partial size 0-0.3mm, moisture content is less than 0.6%；
The natural river sand fineness modulus is 2.4-2.5.
A kind of mortar for adhering heat insulating plate production technology prepared with brick mixed building garbage regeneration powder, includes the following steps:
A. the recycling and screening of the building waste of common brick
Transport the building waste containing common brick cleared of classification to treating construction waste field, using mobile impact crusher and
Screening plant processes building waste, removes the building rubbish containing common brick by sundries sorting and magnetic sorting in screening process
Wood materials, organic material and ferrous material in rubbish, it is containing red that screening, which obtains the building waste containing common brick that partial size is 0-5 millimeters,
The recycled fine aggregate of brick, 5 millimeters the above are the regenerated coarse aggregates containing common brick；
B. it dries
The recycled fine aggregate for being 0-5 millimeters to partial size obtained in step a is dried；In order to sieve；
C. dusting cover point
The recycled fine aggregate for being 0-5 millimeters by the partial size after drying, obtains 0-0.3 millimeters of brick mixed building garbage regeneration powder
Material；
D. it is spare (drying temperature is 90-120 degrees Celsius) that room temperature is down to after natural river sand being dried, moisture content 0-
0.5%；
E. redispersible latex powder, hydroxypropyl methyl cellulose ether, starch ether amalgamation are played into investment blender and stirs 3 points
Clock, until full and uniform；
F. cement, river sand, regenerative powder is added to be mixed 5 minutes, until full and uniform；
G. adding water and stirring the time need to control at 5 minutes, so that regenerative powder sufficiently absorbs water.
Preferably, it is characterized in that: drying in the step b is to be carried out in drying equipment using 90-120 degrees Celsius
Drying, being dried to moisture content is 0-0.5%.
Preferably, the dusting cover point uses aperture to be sorted for 0.3 millimeter of sieve.
Preferably, the recycled fine aggregate after regenerated coarse aggregate and step c dusting cover obtained in the step a point again into
Row drying blows away the powder of the attachment on its surface by pressure-air wind after then spreading out, and the sky of powder will be carried after wind
Gas collection imported into deduster, carries out the separation of air and powder, and the powder after separation is added to the powder after step c dusting cover point
In.
The method have the benefit that:
1. raw material is simple, save the cost.
Mortar for adhering heat insulating plate of the invention is mainly that raw material are brick mixed building rubbish after broken, drying, screening
Obtained regenerative powder, at low cost, production is simple, and technique has expanded the application range of construction refuse resource, environmental protection and energy saving,
Dual value with economic environmental protection.
2. adhesive property is good.
Mortar for adhering heat insulating plate of the invention, as cementitious material, mixes redispersible cream using ordinary portland cement outside
Rubber powder, hydroxypropyl methyl cellulose ether, starch ether improve the adhesion strength of cementitious material, while regenerative powder is active, In
Under the collective effect of these types of raw material, the adhesion strength of cementitious material is significantly improved.Common brick powder content reaches in regenerative micro powder
50%-55%, have light weight, the high feature of water retention, by adhering heat insulating plate on wall after, the moisture kept in mortar,
Slow release is equivalent to the maintenance action carried out to mortar itself, and the adhesion strength of such mortar is just elevated, to make
Adhesive mortar and insulation board, base course wall are sufficiently bonded together, and avoid the problem that falls off in later period.
3. light-weight, the area that paves is big, thermal coefficient is small.
Mortar for adhering heat insulating plate main raw material(s) brick mixed building garbage regeneration powder of the invention, common brick powder content is high, red
Be full of tiny hole inside brick powder, there is lesser bulk density, the regenerative powder mortar for adhering heat insulating plate of same weight compared with
The mortar of other materials with the bigger area that paves when construction, while having smaller thermal coefficient, to building masonry wall again
Heat preservation have humidification.
4. due to being full of tiny hole inside red brick powder, after mortar is completely dry, mortar itself is in similar micropore sea
Continuous shape has preferable flexibility, freeze thawing resistance；Cracking resistance, good weatherability, freedom from cracking, it is not easily to fall off, ensure that and protect outside entire exterior wall
The tightness of warm system significantly improves the durability and quality of its whole building exterior wall.
5, environmentally protective.
Mortar for adhering heat insulating plate of the invention is using brick mixed building garbage regeneration powder as primary raw material.To raising building waste
Utilization rate and the city ecological environment protection be of great significance.
6, mortar for adhering heat insulating plate of the invention has selected redispersible latex powder in the addition of additive, tool
Have that more prominent waterproof performance, adhesion strength are high, flexibility is good, increases the cohesive force of mortar, improves workability, improves
Mobile performance, can be very good to be distributed in entire mortar enhancing water-retaining property, give full play to its superior function.
7, for present invention process process by first drying, the mode of rear wind adheres to again the surface of coarse aggregate and fine aggregate
Fecula material has carried out comprehensive clearing and retrieving, the rate of recovery of regenerative powder is on the one hand improved, on the other hand also by recycled aggregate
Removing surface is clean, make the surface micropore of common brick particle in regenerated coarse aggregate and fine aggregate as early as possible may more than expose, avoid
It is wrapped up and is covered by powder, when being able to ascend regenerated coarse aggregate and fine aggregate production regeneration concrete in this way, aggregate is micro- by its
Being able to ascend for the bond strength of hole and cement slurry, kills two birds with one stone.
8, the experimental results showed that, the apparent density of mortar for adhering heat insulating plate of the present invention is 1800 kilograms per cubic meter, is stretched viscous
Knotting strength can reach standard requirements, and operable time 2.0-3.0 hours, freeze thawing is good, durability is good.Physical properties index
Meet the requirements.
