It is more clearly understood for the purpose, technical scheme and advantage that make the application, below in conjunction with accompanying drawing to the application
Embodiment be described in detail.It should be noted that in the case where not conflicting, in the embodiment and embodiment in the application
Feature can mutually be combined.
Manufacturer and the product type of used part material and reagent in embodiment, see table 1, other raw materials and
Reagent, unless otherwise instructed, is ordinary commercial products.
Table 1
Remarks：The valid density of the material of some in table is the adjustment to commercial product concentration, hereby give notice that.
Embodiment 1
According to API specification, cement mortar is prepared according to the addition in table 2.Respectively at 140 DEG C of 90 DEG C of low temperature and high temperature,
Investigate the thickening situation of the mortar architecture built by different polymer dispersion powder compositions.As a result see table 2.
Wherein：The basic recipe of cement mortar is at 90 DEG C：100.0%API G+x%PSB150+4.0%G80L+1.0%
F45L+1.0%X60L+0.5%H21L+40.0% water, BWOC；

Table 2
In thickening experiment, if when thickening curve, temperature control and normal pressure curve, it may be said that jelly powder good stability,
In the absence of " demulsification " phenomenon.Generally, thickening curve has following three types：
Such as the cement mortar that numbering is 4, the thickening curve at 90 DEG C is shown in Fig. 1 a.This curve is characterized in very typical
" demulsification " phenomenon, show as：Slurry denseness is big, and cement slurry loses flowability before cement is unhydrated.Cause this phenomenon
The reason for be that latex ion stability is poor, mutually aggregation, occur " demulsification ", and make cement slurry denseness increase.Taking out experiment
On slurry page in slurry cup, it is seen that uncured cement slurry loses flowability completely, sees Fig. 1 b.Rubber powder particle occurs " broken
Breast ", cement slurry loses pumpability, it is impossible to meet needs of cementing operations.The feature of this thickening curve uses "×" table in table 1
Show.
Such as the cement mortar that numbering is 7, the thickening curve at 140 DEG C is shown in Fig. 2 a.This curve is characterized in very typical
" cored " phenomenon.It is embodied in：Though consistency curve there may come a time when that normally, temperature control curve occurs in that obvious waveform
Shape.On the slurry page in taking out experiment slurry cup, it is seen that the cement slurry not being fully cured has " cored " phenomenon, sees Fig. 2 b." bag
Core " causes slurry heat transfer uneven, makes multiviscosity meter temperature control curve that wave-like is presented." cored " is also showing for a kind of rubber powder " demulsification "
As cement mortar can also thickened, influence cement mortar is normally pumped.The feature of this thickening curve is represented in table 1 with " ∥ ".
Such as the cement mortar that numbering is 18, the thickening curve at 140 DEG C is shown in Fig. 3 a.This curve be characterized in temperature control and
Pressure curve normal, cement consistency is small, " short transient time " is presented in thickening curve.On the slurry page in taking out experiment slurry cup,
It can be seen that the cement slurry not being fully cured is homogeneous, Fig. 3 b are seen.This explanation rubber powder particle does not occur " to be demulsified ".This thickening
The feature of curve is represented in table 1 with " √ ".
From table 2 it can be seen that the polymer dispersion powder composition of the embodiment of the present application by select suitable stabilizer and
Its addition, can effectively prevent that rubber powder particle from occurring " demulsification " in a low temperature of such as 90 DEG C, or even at a high temperature of 140 DEG C
With also do not occur the phenomenon that " is demulsified " in seawater prepared bentonite drilling fluid, thickening curve is normal.And the stabilizer described in prior art, match somebody with somebody in seawater
When under slurry or high temperature, curve abnormality is thickened, this anomaly is related to rubber powder particle " demulsification ".
As can be seen from Table 2, when using amphoteric surfactant, or by amphoteric surfactant and polyethers nonionic table
The combination of face activating agent is as stabilizer, and its effective addition (valid density of=addition × stabilizer) is based on can
During 0.9-1.8% (BWOR) of the weight of dispersed latex powder, the generation for the phenomenon that can effectively prevent from " being demulsified ".
Embodiment 2
In the mortar architecture by different polymer dispersion powder composition structures, stabilizer is investigated in mortar architecture
In applicability.As a result see table 3.
Table 3
As can be seen from Table 3, in the mortar architecture by different polymer dispersion powder composition structures, at 90 DEG C and
At 140 DEG C, the thickening time shows good linear dependence with retarder, and 24h strength developments are good, illustrates that the application is implemented
The stabilizer of example has adaptability in rubber powder Behavior of Hardened Cement Paste system.
Embodiment 3
With reference to GB/T23445《Polymer cement waterproof paint》Standard, aging 7 days at 80 DEG C are investigated by without anti-
Old agent and with the addition of age resistor polymer dispersion powder composition formation film ageing-resistant situation.As a result see table 4.
Class coating material is constituted substantially during experiment：43%API G+22%B80S+20% water+5%PSB150.Wherein, numbering 1
Also include 30%BWOR stabilizer (LHSB+NP in formula：20+10), numbering 2 also includes 30%BWOR stabilizer in being formulated
(LHSB+NP：20+10) with 0.5%BWOR BHT.
Table 4
From table 4, it can be seen that formed by the class coating material of the polymer dispersion powder composition structure without age resistor
Film is tried, after aging, its tensile strength increases, but elongation at break is obviously reduced, and stretch modulus substantially increases, this explanation examination film warp
Become fragile after aging；The examination film that the class coating material built by the polymer dispersion powder composition that with the addition of age resistor is formed, after aging,
Its elongation at break does not have obvious reduction, and stretch modulus is not also significantly increased, and this explanation the application's includes age resistor
Polymer dispersion powder composition have the advantages that it is anti-aging.
Embodiment 4
According to API specification prepare cement mortar, and at 90 DEG C conserve 2 months after, produce a diameter of 50mm, be highly
100mm cylinder, with reference to ASTM C469《Concrete static modulus and Poisson's ratio bioassay standard》, investigate and divided by different
Dissipate the Mechanical Behavior of Hardened Cement Paste for the mortar architecture that latex compound powder is built.As a result see table 5.
Wherein, the basic recipe of cement mortar is：100.0%API G+x%PSB150+4%G80L+1%F45L+1.0%
X60L+40.5% fresh water, BWOC；Stabilizer and age resistor addition are shown in Table 5.
Table 5
As can be seen from Table 5, when the addition of polymer dispersion powder is identical, the polymer dispersion powder combination containing age resistor
The Behavior of Hardened Cement Paste modulus for the mortar architecture that thing is built, the cement mortar built compared to the polymer dispersion powder composition without age resistor
The Behavior of Hardened Cement Paste modulus of system is low, and Poisson's ratio is big.The reason for causing this phenomenon be：Age resistor can prevent Behavior of Hardened Cement Paste in length
Progressively aging in phase maintenance processes, the Behavior of Hardened Cement Paste that the mortar architecture for building polymer dispersion powder composition is formed remains to keep
Malleable.
Although the embodiment disclosed by the application is as above, described content is only to readily appreciate the application and use
Embodiment, is not limited to the application.Technical staff in any the application art, is taken off not departing from the application
On the premise of the spirit and scope of dew, any modification and change, but the application can be carried out in the form and details of implementation
