Embodiment 1

[0047] The preparation of embodiment 1 mine explosion-proof equipment 1#

[0048] The potting method includes the following steps:

[0049] (1) Put the black fluid two-component novolac epoxy resin and the black fluid epoxy curing agent into an incubator with a temperature of 50°C and a humidity of 2% and heat them for 15 minutes, then take them out Finally, put it into the container according to the mass ratio of 5:1 for full mixing, and use a mixer to fully stir clockwise for 10 minutes. After the two components are fully mixed, let stand at room temperature for 30 minutes to form a fluid hard glue;

[0050] (2) Add a hard rubber toughening agent with 1% of the hard rubber mass into the fluid hard rubber, fully stir clockwise for 10 minutes with a mixer, and let stand at room temperature for 20 minutes;

[0051] (3) Fill the hard glue into a mold with an embedded cavity and one side opening, fix the mold on a high-frequency vibrator, vibrate at high frequency for 5 minutes,...

Embodiment 2

[0068] The preparation of embodiment 2 mine explosion-proof equipment 2#

[0069] The potting method includes the following steps:

[0070] (1) Put the black fluid two-component novolac epoxy resin and the black fluid epoxy curing agent into an incubator with a temperature of 55°C and a humidity of 3% and heat them for 18 minutes, then take them out Finally, put it into the container according to the mass ratio of 5:2 for full mixing, and use a mixer to fully stir clockwise for 13 minutes. After the two components are fully mixed, let stand at room temperature for 40 minutes to form a fluid hard glue;

[0071] (2) Add hard rubber toughening agent with 0.8% hard rubber mass into the fluid hard rubber, fully stir clockwise with a mixer for 12 minutes, and let stand at room temperature for 30 minutes;

[0072] (3) Fill the hard glue into a mold with an embedded cavity and one side opening, fix the mold on a high-frequency vibrator, vibrate at high frequency for 8 minutes, and le...

Abstract

The invention discloses an encapsulation method of mining explosion-proof equipment, and belongs to the mining explosion-proof field. The method comprises the following totally 14 steps that (1) two components of black fluid-shaped double-component novolac epoxy resin and a black fluid-shaped epoxy resin curing agent are put into an incubator with the temperature of 50-60 DEG C and the humidity of 2-5% to heat for 15-20 min, after being taken out, the components are put into a container according to a mass ratio of 5: (1-3) to be full mixed, full stirring is carried out for 10-15 min, standing is carried out at room temperature for 30-50 min after the two components are fully mixed, and fluid-shaped hard rubber is formed. According to the method, a hard rubber shell is prepared, then the hard rubber, soft rubber and explosion-proof particles are used for encapsulating electronic equipment, so that the explosion-proof shell is light and good in insulation effect, meanwhile, the explosion-proof effect is good, strength is high, and the use conditions in severe environments such as a coal mine and the like can be met.

Description

technical field [0001] The application relates to a potting method for mine explosion-proof equipment, which belongs to the field of mine explosion-proof equipment. Background technique [0002] With the development of modern technology, some high-tech electronic products are used more and more in the coal mine field, and how to use these electronic products safely and efficiently has attracted everyone's attention. Due to the harsh environment of coal mines, the requirements for the use of electronic equipment are extremely strict. Most of the coal mine work areas are relatively closed underground and small spaces, dark, humid, and full of dust. Electronic equipment in this environment for a long time will seriously reduce the service life of the equipment. , some devices were directly damaged and could not be used. What's more serious is that the working area is full of flammable gas and dust. Once it encounters an open flame or high temperature, it may explode and cause ...
