In light partition board splicing installation flexible mortar of the present invention, the viscosity of described ether of cellulose is 40000mPas.
In light partition board splicing installation flexible mortar of the present invention, described emulsion comprises defoamer.
The present invention also provides a kind of light partition board to splice mounting process, comprises the following steps:
(a) by cement based powder, emulsion and water in mass ratio 10:0.8-1.2:1.3 mix and stir into flexible mortar, wherein: described emulsion comprises pure acrylic acid polymkeric substance, and the content of described pure acrylic acid polymkeric substance in emulsion is more than 90%;
(b) described flexible mortar is spread upon light partition board side and with shove method dense extrusion;
C () is by floating for the flexible mortar groove position between light partition board.
In light partition board splicing mounting process of the present invention, comprise before described step (c): the groove position press-in grid cloth between light partition board.
In light partition board splicing mounting process of the present invention, described cement based powder comprises ordinary Portland cement, water-ground limestone, medium sand, fine sand and ether of cellulose, and the mass ratio of each component is as follows:
In light partition board splicing mounting process of the present invention, described emulsion comprises defoamer.
Light partition board splicing installation flexible mortar of the present invention and splicing mounting process, by adding the pure acrylic acid polymkeric substance of suitable proportion, greatly can improve sag resistance and the splitting resistance of mortar, the vertical splicing being highly suitable for light partition board is installed, and significantly reduces partition wall splicing installation cost.
Flexible mortar of the present invention also has larger sticking power, improves and concrete adhesiveproperties and snappiness.In addition, by increasing defoamer, the foam in whipping process can be reduced, improve application property.
Accompanying drawing explanation
Fig. 1 is the structural representation using flexible mortar of the present invention to carry out light partition board splicing installation.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Flexible mortar of the present invention is exclusively used in light partition board splicing and installs, this flexible mortar by cement based powder, emulsion and water in mass ratio 10:0.8-1.2:1.3 mix together, wherein: above-mentioned emulsion comprises pure acrylic acid polymkeric substance, and the content of this pure acrylic acid polymkeric substance in emulsion (quality) is more than 95%.
Especially, in above-mentioned flexible mortar, along with the accounting of emulsion increases, its cost increases relatively, properties also improves relatively, and when the ratio of cement based powder, emulsion, water is 10:1:1.3, cost performance is relatively high.
By adding the pure acrylic acid polymkeric substance of suitable proportion, under the prerequisite substantially not increasing cost, substantially increase the sag resistance of mortar, adhesiveproperties and resistance to cleavage, the splicing being highly suitable for light partition board is installed.As shown in table 1, for increasing each performance perameter contrast of mortar before and after emulsion:
Project Without emulsion Add emulsion
Bonding strength MPa 0.4 2.1
Transverse deformation value mm 0.8 2.3
Thermotolerance MPa Without intensity 1.5
Water tolerance MPa 0.2 1.8
Table 1: mortar increases the performance perameter before and after emulsion
Above-mentioned cement based powder comprises ordinary Portland cement, water-ground limestone, medium sand, fine sand and ether of cellulose, and the mass ratio of each component is as follows:
Wherein, the particle diameter of the water-ground limestone adopted in the present embodiment is 200 orders, and the particle diameter of fine sand is 70-140 order, and the particle diameter of medium sand is 40-70 order, and the viscosity of ether of cellulose is 40000mPas.
Certainly, in actual applications, water consumption can suitably change, and only need meet corresponding construction requirement.
For eliminating the foam in flexible mortar whipping process, defoamer can be increased in emulsion.This defoamer non-immediate are added in whipping process, but form emulsion with pure acrylic acid mixed with polymers, greatly can improve application property in actual applications.
Above-mentioned flexible mortar can directly apply to light partition board splicing and install.Now, composition graphs 1, this splicing mounting process comprises the following steps:
(a) by cement based powder, emulsion and water in mass ratio 10:0.8-1.2:1.3 mix and stir into flexible mortar, wherein: emulsion comprises pure acrylic acid polymkeric substance, and the content of pure acrylic acid polymkeric substance in emulsion is more than 95%;
B () uses common grey cutter flexible mortar spread upon the side of light partition board 11 and with shove method dense extrusion, namely completely scrape at 12, the gap that two pieces of light partition boards connect flexible mortar;
C () uses common grey cutter by floating for the flexible mortar groove position 13 between light partition board.
When using above-mentioned flexible mortar to carry out partition wall batten construction, flexible mortar can not trickle downwards because of gravity, thus significantly improves application property, stability and the splitting resistance of partition wall batten splicing.
In addition, in above-mentioned construction technology, the further improving performance of other auxiliary materials can also be added further, such as, in light partition board external coating interfacial agents, the groove position press-in grid cloth etc. between light partition board.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
