Problems solved by technology

[0005] 1. This method cannot avoid excess negative pressure. After the upper flame-retardant slurry is sucked into the board, the slurry will continue to flow through the gaps of the board. If the upper slurry is uneven or insufficient, countless small gaps will be generated between the boards. The air channel cannot achieve the effect of penetrating the flame retardant slurry
[0006] 2. Due to the characteristics of the board itself, if the size of the EPS particles in the board is uneven, the distribution of the EPS particles will be uneven, so that the gaps of the EPS particles in the whole board will not be very uniform, and the negative pressure will make the slurry flow to the gap. Large areas, and areas with small gaps will not or are difficult to feed, so the fireproof panels processed by this method have poor uniformity, and the amount of feed and material consumption is not easy to control
[0007] 3. If this method is used to produce decorative lines, it is subject to large size, specification, and shape constraints. If the thickness is too large, the slurry will not penetrate, because the increase in thickness will inevitably increase the suction of the vacuum pump, and increasing the vacuum on one side will cause Causes the lines to be deformed and flattened, resulting in complete compaction of the pores between the particles
Such as wavy, triangular, trapezoidal lines, etc., this method cannot be produced at all, because the vacuum on one side will make the slurry fully penetrate from the thinner area of ​​the line, while the thicker area will not penetrate
[0008] This shows that the above-mentioned existing equipment for preparing fireproof and thermal insulation materials obviously still has inconvenience and defects, and needs to be further improved urgently

Embodiment 1

[0030] Refer to attached Figures 1 to 3 As shown, the chamber-type vacuum infiltration preparation device includes a vacuum chamber body 2 and a vacuum pump 8 connected thereto. A vacuum outlet valve 12 is arranged on the connecting pipe between the vacuum chamber body 2 and the vacuum pump 8 .

[0031] The vacuum chamber 2 adopts a square chamber structure, which includes a lower chute and an upper cavity above. A feed pipe 16 and a discharge pipe 7 are connected to the side wall of the lower trough, and the feed pipe 16 communicates with a storage tank 22 , and a feed pump 21 is arranged thereon. The feed pump 21 is used to pump the flame retardant slurry in the storage tank 22 into the feed tank. The upper cavity is used for storing prefabricated polystyrene lines 17 . In this embodiment, the prefabricated polystyrene lines 17 are stored in the hollowed-out skip 10 . There is also a pressure relief hole at the top of the upper cavity, and a pressure relief valve 11 is ...

Embodiment 2

[0038] The above-mentioned warehouse-type vacuum infiltration preparation device is used to prepare fireproof and thermal insulation decorative lines. The preparation method is:

[0039] The EPS particles are foamed, matured, molded, and cut to form prefabricated polystyrene lines 17 .

[0040] Place the prefabricated polyphenylene line 17 in the feeding cart 10, open the warehouse body door 1, push the feeding cart 10 along the track 20 into the track structure 13 inside the bin body 2, and control the movement of the feeding cart 10 through the positioning switch 18. Location.

[0041] Start the drive motor 3, the track structure 13 moves down together with the skip 10 and the prefabricated polystyrene lines 17 therein under the drive of the slider 5, and then the feed pump 21 is turned on, and the flame-retardant slurry in the storage tank 22 Pump into the feed tank (in this step, the flame retardant slurry is mixed with a comprehensive ratio of commercially available hal...

Embodiment 3

[0046] The difference between this embodiment and the above-mentioned embodiment 2 is that:

[0047] When the prefabricated polystyrene line 17 enters the interior of the bin body 2 through the feed truck 10, the prefabricated polyphenylene line 17 is retained in the upper cavity in the bin body, and the feed pump 21 is turned on at this time, and the The flame-retardant slurry is pumped into the lower trough until the material liquid reaches the preset value, and the door body 1 is closed. Turn on the vacuum pump 8 and the vacuum outlet valve 12 to evacuate the chamber body 2 until the vacuum pressure is -0.5Mpa, and keep the vacuum state for 30 seconds.

[0048] Then start the driving motor 3 again, so that the prefabricated polystyrene line 17 is immersed in the flame-retardant slurry 19 under the vacuum state, and the vacuum state is kept for 60 seconds.

[0049] Afterwards, open the pressure relief valve 11 of the bin body 2, and when the bin body 2 is in an atmospheric ...

Abstract

The invention discloses a fireproof thermal insulation material as well as a bin type vacuum infiltration preparation device and a preparation method thereof, and belongs to the field of fireproof thermal insulation materials. The preparation method comprises the following steps of putting a prefabricated polyphenyl material and flame-retardant slurry into the same bin body, and conducting evacuation on the bin body; soaking the prefabricated polyphenyl material in the flame-retardant slurry in a vacuum state; and opening a bin body pressure relief hole, moving the polyphenyl material out of the flame-retardant slurry when the bin body is in an atmospheric pressure state, and airing to obtain the fireproof thermal insulation material. The bin type vacuum infiltration preparation device comprises a vacuum bin body and a vacuum pump connected to the vacuum bin body, wherein the vacuum bin body comprises a discharging groove and an upper cavity, and the vacuum bin body further comprises a lifting mechanism for driving the polyphenyl material to move up and down. According to the method, the surrounding environment and pressure of the prefabricated polyphenyl material are changed in a vacuum negative pressure mode, the flame-retardant slurry is deeply infiltrated into gaps of EPS particles through conversion between the vacuum negative pressure and the atmospheric pressure by utilizing the degree of expansion and rebound resilience changes of the EPS particles, infiltration is uniform and thorough, and the flame-retardant effect is lasting.

Description

technical field [0001] The invention relates to the field of fireproof and thermal insulation materials, in particular to a fireproof thermal insulation material and a warehouse-type vacuum infiltration preparation device and preparation method thereof. Background technique [0002] At present, most of the architectural decorative lines used in the market are B-grade EPS lines, A-level GRC lines, and A-level foamed ceramic lines. Among them, the B-grade EPS line is currently the most widely used line with the simplest process and the lowest cost. However, because the line’s combustion level is B1, it is increasingly unable to meet the needs of the current market. Overall A-level development. A-level GRC line is an earlier process, because of its heavy weight, difficult installation, high maintenance costs, and the risk of falling after high-rise buildings are installed, it has been restricted in some areas. Class A foamed ceramic lines, the lines produced by this process c...
