Description

Technical Field

[0001] The utility model relates to the technical field of thermal conductive gel, in particular to a thermal conductive gel with flame retardant performance. Background Art

[0002] Thermally conductive gel is a two-component silicone paste-like thermally conductive filling material. It inherits the advantages of silicone materials such as good affinity, good weather resistance, high and low temperature resistance, and good insulation. At the same time, it has strong plasticity and can fill uneven interfaces. It can meet the heat transfer needs of various applications and has the characteristics of high thermal conductivity, low pressure, high compression ratio, and high electrical insulation. Thermally conductive gel is generally packaged in syringes or in patch form. It is mostly used in LED chips, communication equipment and other fields.

[0003] The flame retardant thermal conductive gel in the prior art is mostly flame retardant by means of a flame retardant layer arranged on its surface. However, since the two sides of the current thermal conductive gel are mostly in contact with devices when in use, the flame retardant layer arranged thereon cannot efficiently perform flame retardant operations, and the edges thereof are exposed to the air. Since no flame retardant layer is arranged, the flame retardant performance of the thermal conductive gel is greatly reduced. In view of this, we propose a flame retardant thermal conductive gel. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a thermally conductive gel with flame retardant properties to solve the technical problem that the current thermally conductive gel is mostly flame retardant by a flame retardant layer arranged on the surface, but because the two sides of the thermally conductive gel are mostly connected to the device, the flame retardant layer arranged thereon cannot efficiently perform the flame retardant operation, and the edge is exposed to the air. Since the flame retardant layer is not arranged, the flame retardant performance of the thermally conductive gel is greatly reduced.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a heat-conducting gel with flame retardant performance, including a heat-conducting part and a flame-retardant part arranged on four sides of the heat-conducting part for side flame retardancy;

[0006] The flame retardant part includes a plurality of thermal insulation strips, which are bonded to the four sides of the heat conducting part, and a plurality of outer folding grooves are equidistantly provided on the outer side of the thermal insulation strips, and a plurality of inner folding grooves are equidistantly provided on the inner side of the thermal insulation strips. The plurality of outer folding grooves cooperate with the plurality of inner folding grooves to enable the thermal insulation strips to adapt to the compression contraction of the heat conducting part.

[0007] Preferably, the heat conducting part comprises a heat conducting layer, the top and bottom of the heat conducting layer are respectively provided with gel layer A and gel layer B, and the bottom of the gel layer B is bonded with an adhesive layer, and the side of the adhesive layer away from the gel layer B is adhered with a protective part.

[0008] Preferably, the protective part includes a release paper layer A and a release paper layer B, and the release paper layer A and the release paper layer B are both adhered to one side of the adhesive layer, and one side of the adhesive layer is formed with a pre-positioning area and a fixing area by the release paper layer A and the release paper layer B.

[0009] Preferably, an inner layer of release paper and an outer layer of folded corner release paper are provided at a corner away from each other of the release paper layer A and the release paper layer B, the outer layer of folded corner release paper is adhered to one side of the adhesive layer, and the outer layer of folded corner release paper is bent toward the side away from the inner layer of release paper.

[0010] Preferably, the heat-conducting layer is made of nylon slurry added with boron nitride, and the heat-conducting layer and the gel layer A and the gel layer B are integrally formed by hot pressing.

[0011] Preferably, two ends of the thermal insulation strip are respectively connected to two adjacent thermal insulation strips by thermoforming, and the thermal insulation strip is made of acrylic resin.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model realizes flame retardant protection for the four sides of the heat conducting part through a plurality of heat insulating strips. When the heat conducting part is put into use, its two sides are abutted against the device, and the four sides are protected by a plurality of heat insulating strips. The heat conducting part can be deformed due to pressure deformation, and folded and contracted through a plurality of outer folding grooves and a plurality of inner folding grooves on the heat insulating strips to reduce the damage of the flame retardant layer caused by pressure, thereby ensuring the subsequent flame retardant protection effect of the thermal conductive gel.

[0014] 2. The utility model realizes the partition of the adhesive layer through the release paper layer A and the release paper layer B. When in use, the release paper layer B can be removed first to expose the pre-positioning area on the adhesive layer for positioning, and then the release paper layer A can be removed for secondary fixation, thereby completing the bonding setting of the heat conductive part. When removing the release paper layer A and the release paper layer B, the outer layer of folded corner release paper can be used to help a corner of the release paper layer A or the release paper layer B to be separated from the adhesive layer, so as to avoid damage to the thermal insulation strip when the user picks up the release paper layer A and the release paper layer B, thereby further ensuring the subsequent flame retardant effect of the thermal conductive gel.
