Abstract
A method for manufacturing an insulation profile. The insulation profile (100) comprises a plurality of microbubbles (20) and at least one protective layer (10) wrapping the plurality of microbubbles (20). The protective layer (10) is provided with an air inlet hole (11) and an air exhaust hole (12). The microbubbles (20) are provided with openings. When the insulation profile (100) is inflated, first air in the microbubbles (20) is drawn through the air exhaust hole (12), then after a first preset period of time, the air exhaust hole (12) is sealed, the air inlet hole (11) is opened to inflate the microbubbles (20) with an insulation gas, and finally, after a second preset period of time, the inflation is stopped, the air inlet hole (11) is sealed to complete inflation. According to the manufacturing method, the air in the insulation profile is completely drawn out, and is then filled with an insulation gas with low coefficient of thermal conductivity, so that the thermal conductivity of the insulation profile is reduced, and the internal and external pressures of the insulation profile are kept in balance, so that the possibility that the performance of the insulation profile is weakened is lowered.

参照图1,图1为本发明的保温型材的制作方法一实施例的流程图。Referring to Figure 1, there is shown a flow chart of an embodiment of a method for fabricating a thermal insulation profile of the present invention.
在本实施例中,该保温型材,包括多个微气泡及包裹所述多个微气泡的至少一层防护层,所述防护层设置有进气孔和排气孔,所述微气泡形成有开口,该制作方法包括以下步骤:In this embodiment, the thermal insulation profile includes a plurality of microbubbles and at least one protective layer enclosing the plurality of microbubbles, the protective layer is provided with an air inlet hole and a vent hole, and the microbubbles are formed with The opening method comprises the following steps:
S30a:经所述排气孔抽取所述微气泡内的空气;S30a: extracting air in the microbubbles through the vent hole;

参照图4,在本实施例中,该保温型材100包括一层防护层10,在其他实施例中,该防护层10还可以由多层防护层10进行叠加,该防护层10包裹多个微气泡20,每一微气泡均20形成有开口(未图示),以方便隔热气体的充入,为了便于保温型材100的气压调节、排除混入的空气、以及充入隔热气体等,在所述防护层10上还设置了便于充气的进气孔11和便于抽空气的排气孔12。Referring to FIG. 4, in the present embodiment, the heat insulating profile 100 includes a protective layer 10. In other embodiments, the protective layer 10 may be superposed by a plurality of protective layers 10, and the protective layer 10 wraps a plurality of micro layers. In the bubble 20, an opening (not shown) is formed in each of the microbubbles 20 to facilitate the charging of the heat insulating gas, and in order to facilitate the air pressure adjustment of the heat insulating profile 100, the removal of the mixed air, and the filling of the heat insulating gas, etc. The protective layer 10 is further provided with an air inlet hole 11 for facilitating inflation and a vent hole 12 for air suction.
由于在保温型材成型100的过程中,所述微气泡20内保留或充入了较多的空气,如果不将其抽出,会严重影响保温型材100的保温性能,所以在该保温型材100成型之后对其进行充气时,需要先使用真空泵或其他抽气装置将所述微气泡20内的空气从所述排气孔11抽出,以便在隔热气体充入之前使得所述微气泡20内保持真空状态。Since the microbubbles 20 retain or are filled with more air during the molding of the heat insulating profile 100, if they are not extracted, the thermal insulation performance of the thermal insulation profile 100 may be seriously affected, so after the thermal insulation profile 100 is molded When inflating it, it is necessary to first evacuate the air in the microbubbles 20 from the vent hole 11 by using a vacuum pump or other air suction means to keep the vacuum inside the microbubbles 20 before the heat insulating gas is charged. status.
进一步地,参照图1和4,由于相邻微气泡20之间形成有间隙,所述间隙内也填充有空气,所以在经所述排气孔12抽取所述微气泡20内的空气的步骤的同时还需要执行步骤S30b,即经所述排气孔12抽取所述间隙内的空气,以使得整个保温型材100在充入隔热气体之前呈真空状态。Further, referring to FIGS. 1 and 4, since a gap is formed between the adjacent microbubbles 20, and the gap is also filled with air, the step of extracting the air in the microbubbles 20 through the exhaust holes 12 is performed. At the same time, step S30b is required to extract the air in the gap through the exhaust hole 12, so that the entire heat insulating profile 100 is in a vacuum state before being filled with the heat insulating gas.
在将所述微气泡20及微气泡20之间形成的间隙内的空气经过所述排气孔12持续抽取第一预设时间之后,密封所述排气孔12,所述第一预设时间由所述微气泡20的总体积和间隙的总体积,以及真空泵或其他抽气装置的抽气速率决定,具体的计算公式为T1=(V1+V2)/Q1,其中,T1为第一预设时间,V1为微气泡20的总体积,V2为间隙的总体积,Q1为抽气速率,并设定所述真空泵或其抽气装置的抽气速率为30-100L/min,以便保温型材100内的空气能在10-40min内完全排出,进而通过密封件密封所述排气孔12,所述密封件可以是电磁阀,也可以是手动控制的低压阀门,在所述排气孔12被密封之后,打开进气孔11,控制充气泵向所述微气泡20内填充导热系数比较低的隔热气体,同时执行步骤S40b,即经所述进气孔11向所述间隙内充入隔热气体,以使得整个保温型材100内充入隔热气体,降低保温型材100的平均导热系数,提高其保温性能。After the air in the gap formed between the microbubbles 20 and the microbubbles 20 is continuously extracted through the exhaust holes 12 for a first predetermined time, the exhaust holes 12 are sealed for the first preset time. Determined by the total volume of the microbubbles 20 and the total volume of the gap, and the pumping rate of the vacuum pump or other pumping device, the specific formula is T1=(V1+V2)/Q1, where T1 is the first preset time. V1 is the total volume of the microbubbles 20, V2 is the total volume of the gap, Q1 is the pumping rate, and the pumping rate of the vacuum pump or its pumping device is set to 30-100 L/min, so that the heat retaining profile 100 The air can be completely discharged within 10-40 min, and the vent hole 12 is sealed by a seal, which may be a solenoid valve or a manually controlled low pressure valve, which is sealed at the vent hole 12. Thereafter, the air inlet hole 11 is opened, and the air pump is controlled to fill the microbubble 20 with a heat insulating gas having a relatively low thermal conductivity coefficient, and at the same time, step S40b is performed, that is, the air gap is filled into the gap through the air inlet hole 11 a gas so that the entire insulation profile 100 is filled with a heat insulating gas, The average thermal conductivity of the thermal insulation profile 100 is reduced to improve its thermal insulation performance.
在向所述微气泡20及微气泡20之间形成的空隙内持续充入第二预设时间的隔热气体之后,停止充气,并密封所述进气孔11,所述第二预设时间由微气泡的总体积、所述间隙的总体积、及充气泵充气的气体流量决定,具体的计算公式为T2=(V1+V2)/Q2,其中,T2为第二预设时间,V1为微气泡20的总体积,V2为间隙的总体积,Q2为充气气体流量,所述充气气体流量为30-100L/min,以便隔热气体能够在10-40min内充满所述保温型材,然后通过密封件密封所述进气孔11,所述密封件可以是电磁阀,也可以是手动控制的低压阀门,此时,所述保温型材100内完全充满导热系数比较低的隔热气体,降低了保温型材100的导热性。
After continuously filling the gap formed between the microbubbles 20 and the microbubbles 20 for the second predetermined time of the heat insulating gas, the inflation is stopped, and the air inlet holes 11 are sealed, the second preset time. It is determined by the total volume of the microbubbles, the total volume of the gap, and the gas flow rate of the air pump. The specific formula is T2=(V1+V2)/Q2, where T2 is the second preset time and V1 is the microbubble. The total volume of 20, V2 is the total volume of the gap, Q2 is the inflation gas flow rate, the inflation gas flow rate is 30-100L/min, so that the heat insulating gas can fill the heat insulating profile within 10-40 min, and then pass the seal Sealing the air inlet hole 11, the sealing member may be a solenoid valve or a manually controlled low pressure valve. At this time, the heat insulating profile 100 is completely filled with a heat insulating gas having a relatively low thermal conductivity coefficient, and the heat insulating profile is lowered.

When the heat insulating profile 100 is inflated, the microbubbles are first extracted through the exhaust holes 12 by an air suction device such as a vacuum pump. The air in 20 is then sealed after the first predetermined time, that is, the time when the predicted air is completely extracted, and the air vent 11 is opened to fill the microbubble 20 with the insulating gas. Finally, After the second predetermined time, that is, after the time during which the predetermined insulating gas can be completely filled according to the total volume of the microbubbles 20, the inflation is stopped, the intake holes 11 are sealed, and the inflation of the heat insulating profile 100 is completed. In the manufacturing method of the present invention, after the air in the heat insulating profile 100 is completely evacuated, the heat insulating gas having a low thermal conductivity is charged, the thermal conductivity of the heat insulating profile 100 is lowered, and the internal and external pressure of the heat insulating profile 100 is balanced, and the heat preservation is lowered. The performance of the profile 100 is weak.
