Embodiment 1

[0038] A kind of invisible tire decorative cover, its structure is as follows figure 1 As shown, the hubcap 1 and the camouflage grass 2 are included, the inner side of the hubcap 1 has a fixed bracket, and the fixed bracket fixes the hubcap on the vehicle hub; the hubcap 1 is a multi-layer structure, and its structure is as follows: figure 2 As shown, it includes substrate 16, infrared stealth coating, radar absorbing coating 13, metal reflective layer 12 and protective layer 11 in sequence; when fixedly connected with the vehicle hub, the protective layer 11 is located near the side of the vehicle hub; The camouflage grass is pasted on the surface of the base material 16 of the hubcap 1 . The specific material selection and optimal design of layer parameters for each layer in the hub cover 1 are as follows:

[0039] Substrate 16 is plastic or fiberglass material material; When substrate 16 is plastic material, described plastic comprises a kind of in epoxy resin, vinyl est...

Embodiment 2

[0047] A kind of preparation method of invisible tire decorative cover:

[0048] Step 1: Preparation of hubcap plastic substrate

[0049] A hub cover metal mold is prepared, and an ABS plastic material is used to prepare a plastic hub cover through an injection molding method.

[0050] Step 2: Preparation of other coatings on the hubcap

[0051] Preparation of phase change microcapsule cooling coating, SiO 2 Airgel thermal insulation coatings, radar absorbing coatings, conductive coatings and polyurea coatings, according to figure 2 The sequence shown is sprayed on the surface of the base material of the hub cover in turn, and the thickness of each layer is 1.5mm, 2mm, 0.8mm, 0.2mm, 1mm, and put into the curing oven for drying.

[0052] Step 3: Camouflage Grass Preparation

[0053] Spray the prepared low-emissivity paint on the surface of a 40 μm thick polyethylene film, the thickness of the sprayed coating is about 60 μm, then cut the cured film into a grass-like structu...

Embodiment 3

[0055] Step 1: Preparation of FRP substrate for hubcap

[0056] Prepare the metal mold of the hub cover, choose epoxy resin as the base material, glass fiber as the reinforcing fiber, and prepare the hub cover by RTM process.

[0057] Step 2: Preparation of other coatings on the hubcap

[0058] Phase-change microcapsule cooling coatings, hollow glass microsphere heat-insulating coatings, radar absorbing coatings, conductive coatings and polyurea coatings were prepared respectively, according to figure 2 The sequence shown is sprayed on the surface of the hubcap base material in turn, and the thickness of each layer is 1mm, 2mm, 0.6mm, 0.3mm, 1.5mm, and put into a curing oven for drying.

[0059] Step 3: Camouflage Grass Preparation

Abstract

The invention belongs to the technical field of functional materials, and provides an invisible tire decorative cover. The invisible tire decorative cover comprises a hub cover (1) and camouflage grass (2); a fixed support is arranged on the inner side of the hub cover (1); the hub cover is fixedly connected on a vehicle hub through the fixed support; the hub cover (1) is of a multi-layer structure and sequentially comprises a base material (16), an infrared camouflage coating, a radar absorbing coating (13), a metal reflection layer (12) and a protective layer (11); when the hub cover (1) isfixedly connected with the vehicle hub, the protective layer (11) is positioned on the side close to the vehicle hub; the camouflage grass is pasted on the surface of the side, away from the infraredcamouflage coating, of the base material (16) of the hub cover (1); and the infrared camouflage coating comprises a cooling coating and a heat insulation coating, wherein phase change capsules are dispersed in the cooling coating, and the heat insulation coating is low in heat conductivity coefficient. The invisible tire decorative cover can solve the problem of invisibility of a tire part of a vehicle, and the infrared camouflage effect is remarkably improved.

Description

technical field [0001] The present invention generally relates to the technical field of functional materials, in particular to a hidden tire decorative cover and a preparation method thereof. Background technique [0002] According to the basic law of Stefan-Boltzmann thermal radiation, the infrared radiation characteristics of an object are determined by the surface temperature and emissivity, and the temperature can affect the perception of the infrared camera more significantly than the emissivity. [0003] The tires of the vehicle will generate a lot of heat due to friction with the drive shaft and the road surface during the rotation process, coupled with solar radiation and ground radiation, the temperature will rise rapidly, so the infrared radiation characteristics of the tires are very obvious. Generally speaking, the radiation temperature of the vehicle is higher than the background, but in the radiation of the whole vehicle body, the radiation of the upper part o...
