Example 1

Fig. 1 and 2 show an aerogel winter protection sole provided in this embodiment. Fig. 1 is an overall appearance diagram of the cold-proof sole, and fig. 2 is an exploded diagram of each layer of the sole.

The cold-proof sole consists of an inner bottom layer 100, an aerogel composite material layer 200, a middle bottom layer 300 and an outer bottom layer 400 which are connected together in an adhesive mode. The inner sole layer 100 is located at the uppermost layer of the shoe sole, the aerogel composite layer 200 is located under the inner sole layer 100, the main body of the midsole layer 300 is located under the aerogel composite layer 200, and the outsole layer 400 is located under the midsole layer 300.

The inner sole layer 100 is simple in shape like an insole, and has a uniform thickness of 3mm throughout the inner sole layer 100. The inner bottom layer 100 is made of polyurethane foam.

The shape of the middle bottom layer 300 is complex and resembles a "boat" with raised edges and a depressed middle. The middle bottom layer 300 is made of polyurethane foam and is 1cm thick. The middle part of the middle bottom layer 300 is provided with a depressed area, and the depth of the depressed area is 3 mm. Two raised supporting strips are arranged in the depressed area, wherein one supporting strip is positioned at the sole part, the other supporting strip is positioned at the heel part, and the height of each supporting strip is 3 mm. As shown in fig. 2, the front support bar 321 and the rear support bar 322 divide the recess into three parts: a front recessed region 311, a middle recessed region 312, and a rear recessed region 313. The edge of the middle bottom layer 300 is a ring of edge raised areas 330, and the inner edge of the edge raised areas 330 is recessed downward to form a ring of edge recessed areas 340.

The curvilinear shape of the edge indentation 340 conforms to the outer edge of the inner bottom layer 100. The top surfaces of anterior support bar 321 and posterior support bar 322 are flush with the bottom surface of rim depression 340. Thus, when the inner bottom layer 100 is overlaid on the middle bottom layer 300, the edge portion of the inner bottom layer 100 is just embedded in the edge recessed region 340 of the middle bottom layer 300. And, the lower surface of the inner bottom layer 100 is in contact with the bottom surface of the rim depression 340, the top of the front support bar 321, and the top surface of the rear support bar 322. At this time, the front recessed region 311, the middle recessed region 312, and the rear recessed region 313 each actually form a closed cavity.

The aerogel composite material layer 200 is filled in the cavity, the thickness of the aerogel composite material layer is 3mm, and micron-sized or nano-sized aerogel powder is mixed with the organic foaming material raw material and foamed together to prepare the foaming material containing aerogel. Preferably, borbo (shanghai) nano-technology limited's bluechia s. kistler aerogel composite is used.

Aerogel composite layer 200 has a thickness equal to the height of forward support bars 321 (rearward support bars 322). As shown in fig. 2, aerogel composite 200 is composed of front composite 210, middle composite 220, and rear composite 230, which are filled in front recessed area 311, middle recessed area 312, and rear recessed area 313, respectively, and are flush with front support bars 321 and rear support bars 322, and then covered with inner bottom layer 100 and fixed, thereby forming a cold-proof sole. When inner bottom layer 100 is stepped on, aerogel composite layer 200 does not receive all pressure because of the support of anterior support strip 321 and posterior support strip 322, and can maintain its shape and thermal insulation performance for a long time.

The outer bottom layer 400 is made of rubber and has a thickness of 5 mm. The bottom of the outer bottom layer 400 contains several non-slip structures 410.

The winter protection sole that contains aerogel combined material that this embodiment provided has kept traditional different material soles self advantage separately, has promoted the winter protection performance of sole simultaneously by a wide margin. The shoes and boots made of the sole can effectively improve the wearing comfort under severe cold conditions.

Example 2

The aerogel winter protection sole that embodiment 2 provided comprises upper bottom layer, lower bottom layer and aerogel composite material layer. The aerogel composite material layer is positioned between the upper bottom layer and the lower bottom layer, and all the layers are connected together in a sewing mode.

Compared with the cold-proof sole in the embodiment 1, the cold-proof sole in the embodiment 2 is mainly characterized in that:

(1) the shape of the raised area in the depressed area in the middle of the lower bottom layer;

(2) the shape of the aerogel composite layer matched with the aerogel composite layer;

(3) the lower bottom layer directly contacts the ground.

The shape of the upper bottom layer in example 2 was identical to that of the inner bottom layer in example 1, and the thickness thereof was 3 mm. The upper bottom layer is made of leather, so that the clothes are comfortable and breathable.

The edge of the lower bottom layer is raised, and the middle part is sunken. The lower bottom layer is made of TPU material and is 1.5cm thick. The middle part of lower bottom is equipped with the depressed area, and the degree of depth of depressed area is 3 mm. A plurality of raised circular supporting blocks are arranged in the sunken area. One part of the supporting blocks is intensively distributed in a sole area, and the other part of the supporting blocks is intensively distributed in a heel area. The circular support blocks function similarly to the support bars in example 1 for supporting the shared pressure. The pressure comes primarily from the ball and heel of the foot, and the support blocks in these areas prevent the pressure from being transmitted directly to the aerogel composite layer. The bottom surface of the lower bottom layer is provided with an anti-skid structure. The shoes made of the cold-proof soles of the embodiment are suitable for being worn indoors.

And the thickness of the aerogel composite material layer is 3mm, and the aerogel and the inorganic material are compounded into the flexible felt material by adopting a nano composite process. Preferably, AG-F series aerogel felts of Shenzhen Zhongji science and technology Limited are used. The aerogel blanket is less costly than the lange heat s.kistler aerogel composite.

The aerogel composite material layer is provided with a plurality of round holes, and the aperture and the number of the round holes are matched with the round supporting blocks in the depressed areas. Thus, the aerogel composite layer is not easily shaken as a whole and is not divided into a plurality of pieces as in example 1. In the middle part depressed area of bottom under the aerogel combined material layer embedding, every round hole cover has strengthened the stability of aerogel combined material layer on the circular supporting shoe that corresponds. And finally, covering the aerogel composite material layer with an upper bottom layer and sewing, thereby obtaining the cold-proof sole.

The winter protection sole that contains aerogel combined material that this embodiment provided simple structure adopts the mature aerogel felt of technique as cold-proof layer, only slightly higher than ordinary winter protection sole cost, has nevertheless promoted the winter protection performance of sole greatly. The shoes and boots made of the sole can effectively improve the foot warmth retention property of indoor activities.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation.
