Problems solved by technology

However, because the polypropylene material itself is a non-polar polymer, its low temperature performance, aging performance, molding shrinkage performance, antistatic performance, etc. are poor, which limits the further application of polypropylene materials.

preparation example Construction

[0099] [Preparation method of polypropylene composite material]

[0100] The present invention also provides the preparation method of above-mentioned composite material, it comprises the steps:

[0101] (1) proportioning polypropylene, high-density polyethylene, silicon micropowder, and EPDM rubber in proportion, stirring and blending in a mixer or mixer;

[0102] (2) Add the above-mentioned compound to the extruder to obtain a flake melt.

[0103] In a preferred embodiment of the present invention, preferably said step (1) is carried out in a high-speed kneader, the stirring and blending time is less than 10 minutes, such as 3-5 minutes; the speed of the high-speed kneader is controlled at 300-500r / min;

[0104] In a preferred embodiment of the present invention, the processing temperatures of the extruder in the preferred step (2) are respectively 130-140°C, 170-180°C, 190-200°C, 200-205°C, 210- 220°C, 220-230°C.

[0105] In a preferred embodiment of the present invent...

Embodiment 1

[0111] Such as Figure 1-3 As shown, the present invention provides a buried box, which includes a box body 1, a box cover 2 and a support frame 6; the support frame 6 is arranged in the box body 1, and is connected with the box body 1 and the box cover 2. The inner surface is bonded; the box body 1 and the box cover 2 are made of plastic, and the support frame 6 is made of metal; as Figure 4 with 5 As shown, the support frame 6 includes:

[0112] The upper frame 61, the lower frame 62, the beam 63, the first side frame 64, the second side frame 64', the first outer rail 65 and the second outer rail 65'; the upper frame 61 and the lower frame 62 are arranged in parallel ;

[0113] The first side support 64 includes a bottom and two sides perpendicular to the bottom; the second side support 64' includes a bottom and two sides perpendicular to the bottom;

[0114] The first side bracket 64 and the second side bracket 64' are disposed parallel to each other between the upper...

Embodiment 2

[0126] The method of assembling the buried box described in Embodiment 1 first assembles the support frame 6 without assembling the upper frame 61 temporarily; places the support frame 6 in the box body 1 and puts the battery into the support frame 6, and then installs the upper frame 61 And the sealing cap on the upper frame; Optionally, assemble other accessories; Install the first sealing gasket 3 on the end face that the box body 1 and the box cover 2 are connected to each other, and fasten the box body 1 and the box cover 2 with bolts, that is, realize In the assembly process of the buried box, it can be placed in the underground and other places.

[0127] Specifically, when assembling the supporting frame 6, the specific steps may be as follows:

[0128] The following frame 62 is installed as a benchmark, and the first side support 64 and the second side support 64 ' are first selected, that is, the first side support 64 and the second side support 64 ' are fixedly conne...

Abstract

The invention provides an underground system for electrical equipment. The underground system comprises an underground box, wherein the underground box is internally provided with a supporting frame,and the supporting frame is reasonable in structural design, convenient to disassemble and assemble and high in supporting strength. When the underground box is arranged underground, the pressure bearing strength of the box body can be improved and can reach more 2 tons or above. Due to the factor that the supporting frame is detachable, the transportation is facilitated. Compared with an underground box which is only composed of a thick and heavy metal box body and a box cover in the prior art, the underground box is light in weight, easy to transport and convenient to move. The box body andthe box cover in the underground box are connected in a sealed manner through a sealing gasket and / or a groove body structure, and the sealing grade can reach more than IP67 or above; the undergroundbox is attractive in overall appearance, has the characteristics of moisture resistance, water resistance and dust prevention, and has the functions of corrosion resistance, high humidity resistance and low temperature resistance; and the box body and the box cover are easy to process, the size is not limited by processing conditions, and the production cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of buried electrical equipment, and in particular relates to a buried system for electrical equipment. Background technique [0002] With the extensive development and use of batteries, especially batteries, in various fields, the tools for loading the batteries also need to be developed and designed. Currently known electrical equipment such as batteries are mostly stored in boxes on the ground, which indirectly leads to It is contradictory in terms of waterproof, heat dissipation, exhaust, etc., and there is a risk of being easily stolen. Today, a small number of base stations in some provinces have begun to use buried box structures. However, the airtight box body of the currently disclosed buried box is rough and simple in workmanship, and adopts steel products, which are not resistant to acid and alkali, and are easy to corrode and rust, and are easy to enter water; it is difficult to meet its long-ter...
