Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1
Referring to fig. 1 and 2, fig. 1 and 2 are process schematic diagrams of a preparation process of a basalt fiber reinforced PVC composite material according to an embodiment of the present invention.
Specifically, the preparation process of the basalt fiber reinforced PVC composite material adopts a compact sintering process to prepare a basalt fiber reinforced PVC composite material sample, and comprises three steps of S1, loading, S2, mixing, S3 and pressing and sintering.
In step S1, basalt fiber material and PVC powder material are charged into the cavity of the pressing mold at a set mixing ratio, wherein the set mixing ratio is determined according to the sample requirement, and in general, basalt fiber material and PVC powder material may be represented by volume=1 (2 to 40), preferably=1 (10 to 30).
As shown in the figure, the pressing mold in this embodiment is a vertical mold, and includes a side mold 1, a top mold 2 and a bottom mold 4, where the side mold 1, the top mold 2 and the bottom mold 4 enclose a mold cavity, and the top mold 2 is connected with a pressing head 3 and is disposed opposite to the bottom mold 4, and can be driven by the pressing head 3 to move toward the bottom mold 4 to press the mixed material 8 in the mold cavity.
With continued reference to fig. 1 and 2, it can be seen that a plurality of air inlet channels 5 are provided through the side mold 1, preferably such that the plurality of air inlet channels 5 are uniformly distributed along the circumference of the side mold 1, the air inlet of the air inlet channels 5 is connected to an external air source pipe 6, and the air outlet of the air inlet channels 5 is inclined towards the bottom of the mold cavity. With this arrangement, in step S1, the basalt fiber material and the PVC powder material charged into the cavity of the pressing die may not be mixed in advance (or simply premixed) at all, so that the rapid and uniform and effective mixing is performed in the next step S2.
Specifically, in step S2, working gas is introduced into the cavity of the pressing mold through the air inlet channel 5 of the pressing mold, and the basalt fiber material and the PVC powder material are mixed by shaking under the blowing of the working gas until the basalt fiber material and the PVC powder material are uniformly mixed, wherein the working gas is a high-pressure gas at a low temperature and/or a high temperature, preferably a non-reactive gas such as nitrogen or argon, but not excluding optional compressed air, and is introduced into the air inlet channel 5 through the air source pipeline 6.
Considering the situation that the traditional pneumatic mixing mode is easy to generate uneven mixing when preparing the basalt fiber material and PVC powder material, the improved two-step method can be adopted when adopting the scheme of the embodiment to carry out pneumatic mixing of basalt fiber material and PVC powder material, when high-pressure gas is introduced through the air inlet channel 5, the first step is to fully mix basalt fiber material and PVC powder material for a period of time by introducing normal-temperature gas, so that the basalt fiber material and PVC powder material are fully and uniformly mixed in the airflow vibration process, and the second step is to introduce heated high-temperature gas to enable the basalt fiber material and PVC powder material to generate surface infiltration at high temperature, thereby reducing the separation of the basalt fiber material and PVC powder material in the sedimentation process after vibration, controlling the temperature of the high-temperature gas to be more than 120 ℃ and not more than 250 ℃ at most, so that the material just generates surface infiltration without obvious melting of PVC powder material.
The top mold 2 of this embodiment is preferably provided with ventilation holes, and the top mold 2 may be made of ventilation material, so as to ensure smooth mixing and subsequent pressing.
The next step is S3, pressing and sintering, specifically, applying pressure to a die cavity of a pressing die through a pressing head 3, pressing the uniformly mixed basalt fiber material and PVC powder material into a green body, and sintering the green body into a basalt fiber reinforced PVC composite sample.
In step S3, the basalt fiber reinforced PVC composite sample is preferably sintered by hot pressing, that is, the pressing mold itself has a heating function (not shown in the drawing), and when pressure is applied to the cavity of the pressing mold by the pressing head 3, the basalt fiber material and the PVC powder material are heated by the pressing mold, and the basalt fiber material and the PVC powder material are hot pressed into the basalt fiber reinforced PVC composite sample.
As further shown in fig. 1 and 2, the bottom die 4 in this embodiment is an elastic bottom die, and an elastic component 7 is disposed below the elastic bottom die, which is beneficial to playing a role of buffering in the pressurizing process and facilitating the demolding of the sample.
Preferably, in step S3, after the basalt fiber material and the PVC powder material in the cavity of the pressing mold are pressurized by the pressing head 3, the air outlet of the air inlet passage 5 is located outside the compressed cavity due to the movement of the top mold 2 and the bottom mold 4, and this design can reduce the influence of the pressing process on the air inlet passage 5.
Example 2
This example is another possible means proposed for the manner in which the basalt fiber-reinforced PVC composite sample of example 1 is sintered, in example 1, the pressing die itself has a heating function (not shown in the drawing), and when pressure is applied to the cavity of the pressing die by the pressing head 3, the basalt fiber material and the PVC powder material are also heated by the pressing die, and the basalt fiber material and the PVC powder material are hot-pressed into the basalt fiber-reinforced PVC composite sample.
The difference in this embodiment is that in the "press sintering" of step S3, the pressing mold itself is not used as a sintering mold any more, after the uniformly mixed basalt fiber material and PVC powder material are pressed into a green body by the pressing head 3, the green body is demolded from the pressing mold, and then the demolded green body is sintered into a basalt fiber reinforced PVC composite sample in another sintering apparatus (hot press furnace, vacuum sintering furnace, atmosphere sintering furnace, isostatic pressing sintering furnace, etc.).
The preparation process of the basalt fiber reinforced PVC composite material provided by the embodiment does not need to adopt special equipment such as a ball mill or a three-dimensional stirrer to carry out long-time mixing operation in the process of manufacturing the basalt fiber reinforced PVC composite material sample by adopting a hot pressing method, only needs to directly introduce working gas into a die cavity of a pressing die, can fully vibrate and uniformly mix the basalt fiber material and the PVC powder material under the blowing of the working gas by controlling the conditions such as a gas flow path, the temperature and the like, realizes quick and uniform mixing, does not damage the fiber material, and therefore has outstanding contribution in the aspect of efficiently preparing the basalt fiber reinforced PVC composite material or even similar composite material.
In the foregoing, only the preferred embodiments of the present invention are described, and any person skilled in the art should, within the scope of the present disclosure, be able to substitute or change the technical solution according to the present invention and the inventive concept thereof, and should be covered by the protection scope of the present invention.
