Description
Technical Field
The invention relates to the technical field of powder materials. And more particularly, to hollow glass microspheres obtained by a method for improving the durability of hollow glass microspheres.
Background
The composite material plays an important role in the field of advanced material lightweight, and the hollow glass microspheres are widely used as a density regulator of the composite material, so that the density of a composite material system is reduced on the premise of ensuring certain strength. Compared with a common hollow foaming structure, the introduction of the hollow glass microspheres reinforces the cell structure through the spherical shell thereof while forming closed cells (to reduce density), so that higher strength can be obtained while having low density. For the composite material using the hollow glass microspheres as the light-weight high-strength filler, the hollow glass microspheres are generally filled in a large proportion to reduce the density of the composite material as much as possible. As a class of particles with micron-sized particle size and submicron-sized thin spherical shell structure, the mechanical properties of the hollow glass microspheres are greatly different from those of a common polymer matrix, and the structural uniformity, the mechanical strength and the stability of the mechanical properties of the composite material can be obviously influenced by the large-proportion filling of the hollow glass microspheres.
When the hollow glass microsphere is formed, in order to easily form a perfect thin-wall hollow spherical shell structure, a large amount of alkali metal and alkaline earth metal ions are generally introduced into a glass system. As a destructing body of the glass network, the existence of the ions can obviously lower the melting point of the silica which is the main body of the glass microsphere, and is convenient for forming. However, the presence of these alkali metal and alkaline earth metal ions also leads to a decrease in the strength of the shell of the hollow glass microspheres and a deterioration in the weather resistance. Whether the hollow glass microspheres are used as particles alone (such as a carrier of a micro-nano functional structure) or used as a light filler of a composite material, the high alkali content of the spherical shell is not favorable for the long-term stability (including the stability of chemical composition and structural strength) of the hollow glass microspheres. Taking the filler as the composite material as an example, when the hollow glass microspheres are filled in a large proportion, a weak area is formed in the composite material, so that the performance of the composite material is weakened. For composite materials used in hot humid or hydraulic environments, the situation is exacerbated by the temperature and pressure promoting the diffusion of water vapor.
Therefore, whether the hollow glass microsphere is used as a light filler or a light carrier, finding a proper treatment method to improve the stability of the chemical composition and the physical structure of the hollow glass microsphere has important application value.

Detailed Description
In order to make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
It is noted that all numerical designations of the invention (e.g., temperature, time, concentration, weight, and the like, including ranges for each) may generally be approximated as appropriate by changes (+) or (-) in increments of 0.1 or 1.0. All numerical designations should be understood as preceded by the term "about".
Example 1
In this example, the method of the present invention was used to treat the self-made hollow glass microspheres
The preparation of the self-made hollow glass microsphere is realized according to patent 201210056295.5 'a soft chemical preparation method of hollow glass microsphere, the prepared hollow glass microsphere and application thereof'. TheThe density of the hollow glass microspheres is 0.30g/cm3The type is T30, the granularity is 20-80 mu m, and the acid selected in the acidification treatment is 1mol/L hydrochloric acid.
The steps of surface treatment of the hollow microspheres in this example are as follows:
firstly, carrying out hollow glass microsphere flotation: standing and layering the hollow glass microspheres and ethanol according to the volume ratio of 1:1, taking an upper floating material, filtering, and drying for later use.
And then carrying out acid leaching treatment on the floated hollow glass microspheres: preparing 1mol/L hydrochloric acid solution, controlling the volume ratio of the hollow glass microspheres to the acid solution to be 1:1, mechanically stirring for 10min, filtering, cleaning with ethanol, drying, screening to remove agglomerated particles, and placing into a dryer for later use.
Example 2
This example mainly examines the acid leaching effect of hollow glass microspheres. The hollow glass microspheres which are subjected to acid leaching in the embodiment 1 are subjected to acid leaching again, and the solution and the hollow glass microspheres which are subjected to acid leaching are subjected to component testing and analysis.
The steps of processing the hollow glass microspheres in this example are as follows:
taking out the treated hollow glass microspheres from the dryer for acid leaching treatment: preparing 1mol/L hydrochloric acid solution, controlling the volume ratio of the hollow glass microspheres to the acid solution to be 1:1, mechanically stirring for 10min, filtering, cleaning with ethanol, drying, screening to remove agglomerated particles, and placing into a dryer for later use.
XRF test is carried out on the original hollow glass microspheres, the hollow glass microspheres after the first acid leaching treatment and the hollow glass microspheres after the second acid leaching treatment, and the content of each oxide of the microspheres is tested, and the result is shown in figure 2. As can be seen from FIG. 2, Na in the blank hollow glass microspheres2The contents of O, CaO and ZnO are all higher, and Na on the surfaces of the microspheres is obtained after acid leaching treatment2The contents of the three main alkaline oxides in the microspheres are changed slightly after the second acid leaching treatment, which shows that the alkaline oxides on the surfaces of the microspheres are precipitated as much as possible during the first acid leaching treatment.
The blank hollow glass microspheres, the hollow glass microspheres after acid leaching and the hollow glass microspheres after acid leaching in example 1 were placed at 40 ℃ and 93% humidity, and the weight gain and strength change of the microspheres are shown in table 1:
TABLE 1 humid heat aging test condition table for hollow glass microsphere
Description of the drawings: the method for measuring the volume survival rate under a pressure of 10MPa in Table 1 is referred to in patent 201410196976.0 "a method for measuring the isostatic strength of hollow glass microspheres".
As can be seen from Table 1, the volume survival rate of the hollow glass microspheres is slightly reduced under the pressure of 10MPa before and after the acid leaching treatment, which is mainly because the alkaline oxides on the surfaces of the microspheres are precipitated after the acid leaching treatment to form smaller surface defects, thereby affecting the compressive strength of the material. After the hollow glass microspheres are aged for 15 days at 40 ℃ and 93% of temperature and humidity, the weight gain percentage of the microspheres is greatly reduced, and the fact that the hygroscopicity of the microspheres is reduced and the durability is improved after the hollow glass microspheres are subjected to acid leaching can be concluded.
The ICP test was performed on the deionized water, the solution obtained after soaking the hollow glass microspheres in deionized water, the solution obtained after the first acid leaching, and the solution obtained after the second acid leaching in the acid solution prepared in example 1, and the content changes of Ca, Na, and Zn in the test solutions were as shown in table 2:
TABLE 2 variation of Ca, Na, Zn contents in the solution
| Serial number | Sample (I) | Ca(μg/g) | Na(μg/g) | Zn(μg/g) |
| 1 | |
0 | 0 | 0 |
| 2 | Deionized water soaked hollow glass microsphere | 47.034 | 112.65 | 0.245 |
| 3 | Solution after primary acid leaching | 538.17 | 1.08×103 | 73.74 |
| 4 | The solution after the second acid leaching | 3.18 | 5.33 | 0.72 |
As can be seen from table 2, a small amount of alkaline oxide particles exist on the surface of the hollow glass microsphere, and are directly soaked in deionized water, so that the amount of precipitated alkaline oxide is small, the amount of precipitated alkaline oxide is greatly increased after acid leaching, and the amount of alkaline ions in the precipitated liquid is very small after acid leaching again, which indicates that the alkaline particles precipitated on the surface of the hollow glass microsphere by the first acid leaching are relatively complete, and the acid leaching effect is good.
