Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a heat-insulating sunshade pad for automobiles is sequentially bonded with a metal reflective film 2, a tear-resistant layer 3, a glass wool structural layer 4 and a flexible heat-conducting layer 6 from top to bottom, and the metal reflective film 2 is far away from the tear-resistant One side of layer 3 is evenly coated with fluorocarbon varnish 1, the tear-resistant layer 3 is woven with high-strength yarn, and the side of the glass wool structure layer 4 bonded with the flexible heat-conducting layer 6 is provided with several cone bases, inside the cone base Filled with phase change material 5 , the flexible heat conduction layer 6 is bonded to the glass wool structural layer through an adhesive coating 7 .

[0037] Glass wool structure layer 4, glass wool has good heat insulation effect, but also has good toughness and stability. When it is used for heat insulation sunshade pad, it can play a good heat insulation effect on...

Embodiment 2

[0079] The second embodiment is the same as the first embodiment, except that the solid-liquid phase change material is composed of the following by mass percentage: expanded graphite 9%, binary eutectic fatty acid 82%, porous magnesium oxide 1%, porous poly 5% ester fiber, 3% carboxymethyl cellulose, in which the binary deep eutectic fatty acid is blended from lauric acid and myristic acid.

Embodiment 3

[0081] Embodiment three is the same as embodiment one and embodiment two, and the difference is that the solid-liquid phase change material is composed of the following by mass percentage: expanded graphite 7%, binary eutectic fatty acid 83%, porous magnesium oxide 5% %, porous polyester fiber 3%, carboxymethyl cellulose 2%, of which the binary eutectic fatty acid is blended from lauric acid and myristic acid.

Abstract

The invention discloses a thermal-insulation sunshade pad for cars. The thermal-insulation sunshade pad comprises a metal reflecting film, an anti-tear layer, a glass-wool structural layer and a flexible thermal-conduction layer which are sequentially adhered from top to bottom. One side, away from the anti-tear layer, of the metal reflecting film is evenly coated with fluorocarbon varnish. The anti-tear layer is woven by high-strength yarn. One side, adhered to the flexible thermal-conduction layer, of the glass-wool structural layer is provided with a plurality of conical substrates filled with phase-change materials. The flexible thermal-conduction layer is adhered to the glass-wool structural layer through adhering coating. The thermal-insulation sunshade pad has the advantages that the thermal-insulation sunshade pad is evident in effect and can keep the temperature in a car below 36 DEG C and the temperature of a car body below 39 DEG C when the air temperature is 30 DEG C, the total thickness of the thermal-insulation sunshade pad does not exceed 1cm, and the thermal-insulation sunshade pad is foldable, convenient to carry and use and easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of automobile sunshade pads, in particular to a thermal insulation sunshade pad for automobiles. Background technique [0002] As a tool for people's outdoor activities, cars have a very high probability of being exposed to strong light from the outside, and the time is very long, especially with the advent of hot summer, many people's cars are parked in open-air parking lots. After exposure to the sun, when people return to the car When inside, the temperature inside the car is so high that people can’t bear it at all. After field tests, on a sunny day in Chengdu City, Sichuan Province, when the outside temperature was 32°C, the car without sunshade pads was parked in the open-air parking lot for 1 hour. , Use a thermometer to measure the temperature inside the car. The test result shows that the temperature in the cab of the car reaches 65°C, which is 33°C higher than the outside temperature. At this tempe...
