Description
Technical Field

The silicone rubber is a solid product formed by molding a liquid state of the silicone rubber through a mold, and is widely applied to occasions of high and low temperature, structural stress, water and oil resistance, medical appliances and the like. After the liquid silicone rubber is synthesized, the liquid silicone rubber needs to be transferred to an intermediate container for centralized storage, and after the liquid silicone rubber contacts air or is in an unsuitable temperature and humidity environment, the phenomenon of solidification layering is easy to occur, and solidified accumulated substances are concentrated on the lower layer and are not easy to detect and judge on the appearance; in addition, since the shrinkage rate of the cured silicone rubber is very small, the proportion of the curing components and the curing speed cannot be accurately detected, so that the optimal temperature and humidity data cannot be obtained, the temperature and humidity range can be controlled only by experience, and the storage and delivery quality of silicone rubber products are not facilitated.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a silicon rubber curing rate detection device which is used for realizing accurate and effective quality detection on the curing layering rate of a silicon rubber liquid product.
The utility model is implemented by the following technical scheme: a silicon rubber curing rate detection device comprises an experiment tank, a measuring and reading tube, a thermometer and a hygrometer. The experimental tank is a flat hollow container, the upper opening of the experimental tank is provided with one measuring and reading tube in a sealing butt joint mode, the measuring and reading tube is a slender glass tube body, the side wall of the tube body is provided with vertically arranged scale marks, and meanwhile, the tube opening is also provided with a sealing cover; the thermometer and the hygrometer are both arranged on the experiment tank.

Furthermore, a silicon rubber material is filled in the experiment tank.
Further, the inner diameter of the cross section circle of the reading measuring pipe is smaller than 1/5 of the inner diameter of the cross section circle of the experiment tank.
The utility model has the beneficial effects that: the utility model utilizes the structure that the slender measuring and reading tube is arranged above the flat experimental tank to contain the liquid silicone rubber, when part of the liquid silicone rubber in the experimental tank at the bottom is solidified and contracted, the liquid material in the measuring and reading tube is rapidly supplemented downwards and the liquid level surface is reduced, because the inner diameter of the measuring and reading tube is far smaller than the inner diameter of the experimental tank, the micro shrinkage rate of the silicone rubber during solidification can be amplified and displayed, a measurer can detect the solidification proportion and the solidification speed by greatly reducing the scale value of the liquid level surface, and simultaneously, the temperature and humidity meter regularly records the numerical value to obtain the optimal storage temperature and storage humidity of the product, thereby overcoming the problem that the prior art is difficult to accurately detect because the solidification shrinkage rate of the silicone rubber is low; in addition, the technology can also accurately detect the curing rate of the silicone rubber product in various preparation processes and storage environments, and has excellent promotion effects on improving the quality of the silicone rubber product and optimizing the preparation process.

Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
As shown in figure 1, the device for detecting the curing rate of the silicone rubber comprises an experimental tank 1, a measuring and reading tube 2, a thermometer 3 and a hygrometer 4. Wherein, the experimental tank 1 is a flat hollow container, the upper opening of the experimental tank is provided with one measuring and reading pipe 2 in a sealing butt joint mode, and the bottom of the experimental tank is provided with a discharge valve 1 a; the measuring and reading tube 2 is a slender glass tube body, the designed inner diameter of the cross section circle of the measuring and reading tube is 1/5 smaller than the inner diameter of the cross section circle of the experimental tank 1, the side wall of the tube body is provided with vertically arranged scale marks 2a, and the tube opening of the measuring and reading tube is also provided with a sealing cover 2 b; the thermometer 3 and the hygrometer 4 are both fixedly arranged on the experiment tank 1.
The working principle of the utility model is as follows:
the method comprises the following steps: as shown in fig. 2, the seal cover 2b is opened to inject the liquid silicone rubber sample into the measurement and reading tube 2 and the experimental tank 1, so as to ensure that the inner cavity of the experimental tank 1 is completely filled with the silicone rubber, and the liquid injection is stopped when the liquid level reaches 0 scale of the uppermost part of the graduation line 2a on the measurement and reading tube 2, and the seal cover 2b is closed (the seal cover 2b is only used for preventing the experimental article from being polluted by external impurities and does not need to be sealed).
Step two: placing the integrated device subjected to material injection in the step A in an environment A, respectively measuring the environment temperature A and the environment temperature A through a thermometer 3 and a hygrometer 4, and standing for several days until the silicon rubber is partially solidified; when the solidification shrinkage of partial liquid silicon rubber in the experiment tank 1 at the bottom occurs, the liquid material in the measuring and reading tube 2 is rapidly supplemented downwards and the liquid level surface of the liquid material is descended, because the inner diameter of the measuring and reading tube 2 is far smaller than the inner diameter of the experiment tank 1, more materials need to be supplemented downwards, and the liquid level of the silicon rubber will be rapidly descended, so that the micro shrinkage rate during the solidification of the silicon rubber can be amplified and displayed, at the moment, a measurer only needs to record the height descending value of a scale mark 2a where the liquid level surface is located, and the solidification rate and the solidification speed of the silicon rubber material can be accurately obtained according to the initial volume of the silicon rubber. And then, opening the discharge valve 1a to empty the materials in the whole device, injecting new silicon rubber sample materials again in the same way as in the step one, placing the whole device in an environment B, performing the same standing solidification and detection recording work as described above, comparing the advantages and disadvantages of the silicon rubber solidification rates in the environment A and the environment B, marking the experimental parameters with lower solidification rates to obtain a better storage environment and temperature and humidity, and repeatedly performing the comparison work to finally obtain the optimal storage temperature and storage humidity of the silicon rubber product.
Step three: emptying materials in the whole device, re-injecting new silicon rubber sample materials according to the step one, sequentially injecting the silicon rubber materials A obtained by the process A into the experimental tank 1-level measurement and reading pipe 2, standing for several days, and recording the liquid level position displayed by the scale mark 2a of the measurement and reading pipe 2 by a measurer at the moment to obtain an accurate curing rate parameter because the measurement and reading principle of curing shrinkage is explained in the step two; and emptying the silicon rubber material A through a discharge valve 1a, re-injecting the silicon rubber material B obtained by the process B, performing the same curing recording work, comparing the quality of the silicon rubber curing rate parameters of two batches of different processes, and marking the parameter with the lower curing rate to obtain the relatively better silicon rubber preparation process.
The foregoing is merely a preferred embodiment of this invention and is not intended to limit the utility model in any manner. It should be understood that other modifications, changes and substitutions may be made without departing from the spirit and scope of the present invention, which should be considered as within the spirit and scope of the present invention.
