Specific examples thereof are as follows.

Example one

Referring to the attached drawing 3, the heat preservation and insulation aluminum alloy door and window of the embodiment comprises two aluminum alloy sections 1 which are oppositely arranged, and two heat insulation strips 2 which are arranged between the two aluminum alloy sections 1, wherein aerogel felts 4 are tightly arranged between the two heat insulation strips 2.

In this example, the aluminum alloy profile 1 was extruded by an existing extruder. Two symmetrically arranged tooth-opening notches 11 are respectively arranged on the opposite surfaces of the two aluminum alloy profiles 1 and used for being clamped into the heat insulation strips 2. In the embodiment, the thermal insulating strip 2 is a nylon thermal insulating strip.

In the embodiment, before the aerogel felt 4 is used, the aerogel felt is cut into a U-shaped space 12 formed by two aluminum alloy profiles 1 and two heat insulation strips 2. In order to satisfy the requirement of tightly filling the U-shaped space 12 with the aerogel blanket 4, the compression amount of the aerogel material is required to be set aside in advance, for example, the volume of the aerogel blanket 4 cut in advance is more than 15% of the theoretical volume of the U-shaped space.

Referring to fig. 4, in order to fill and compact the aerogel blanket 4 in the U-shaped space 12 and avoid the problem that the aerogel is easily not filled in place and has dead corners and gaps when being injected under high pressure, the preparation method adopted in this embodiment is as follows:

(1) one end of each of the two heat insulation strips 2 penetrates into the notched opening 11 of the aluminum alloy section 1 on one side;

(2) inserting the cut aerogel felt 4 into a U-shaped space 12 formed by the aluminum alloy section bar 1 and the two heat insulation strips 2;

Example two

The difference between this embodiment and the first embodiment is that the aerogel plate 4' is tightly disposed in the U-shaped space of the al-alloy door/window.

The difference is that the method for inserting the aerogel plate 4' into the U-shaped space is as follows: a U-shaped lining paper is arranged below the aerogel plate 4 ', the aerogel plate 4 ' is positioned inside the U-shaped lining paper, and the U-shaped lining paper and the aerogel plate 4 ' arranged inside are pushed together into the U-shaped space 12.

The insertion method of the aerogel plate utilizes the smoothness of the outer side of the U-shaped liner paper to more conveniently and quickly realize the insertion of the aerogel plate and improve the manufacturing efficiency.

Therefore, the heat-preservation and heat-insulation aluminum alloy door and window prepared by the preparation method not only contains the aerogel plate 4 ', but also is provided with the U-shaped lining paper on the outer side of the aerogel plate 4'.

EXAMPLE III

The difference between this embodiment and the first embodiment is that the aerogel plate 4' is tightly disposed in the U-shaped space of the al-alloy door/window.

The difference is that the method for inserting the aerogel plate 4' into the U-shaped space is as follows: the U-shaped lining paper is arranged below the aerogel plate 4 ', the aerogel plate 4 ' is positioned in the U-shaped lining paper, a gap is reserved between the aerogel plate 4 ' and the U-shaped lining paper, the U-shaped lining paper and the aerogel plate 4 ' are pushed into the U-shaped space 12 together, and meanwhile, polyurethane foaming glue is injected into the gap reserved between the aerogel plate 4 ' and the U-shaped lining paper.

The insertion method of the aerogel plate is characterized in that the smoothness of the outer side of the U-shaped liner paper is utilized, so that the aerogel plate 4' can be inserted more conveniently and rapidly, and the manufacturing efficiency is improved; secondly, the polyurethane foaming adhesive is used for filling a gap between the aerogel plate 4' and the U-shaped liner paper, and after the polyurethane is solidified, the U-shaped space can be filled and filled better, so that the heat insulation and sound insulation effects are further improved.

Therefore, the heat-preservation and heat-insulation aluminum alloy door and window prepared by the preparation method not only contains the aerogel plate 4', but also is provided with the U-shaped lining paper on the outer side, and the polyurethane foaming glue is arranged between the aerogel plate 4 and the U-shaped lining paper.

Of course, still can set up many aerogel felts or aerogel board between two heat insulating strips according to actual conditions, all fill polyurethane foam between many aerogel felts or the aerogel board, further promote the complex of aerogel and polyurethane material.

And through contrast research, the aerogel felt or aerogel plate is filled in the cavity position between the two heat insulation strips, and the heat insulation performance of the whole window is improved more excellently than the cavity position filled in the aluminum alloy section bar, the heat transfer coefficient is reduced more, and the manufacturing method is simple and feasible.
