Flexible heat conduction paint for automobile heat insulation

Abstract

The invention discloses flexible heat conduction paint for automobile heat insulation. The flexible heat conduction paint is prepared from, by weight, 34-39 parts of organic silicone modified acrylic resin, 7-9 parts of expanded graphite, 12-15 parts of heat conduction fiber, 6-8 parts of mica powder, 5-7 parts of transition metal composite oxide powder, 9-11 parts of butyl acetate, 0.5-1 part of fumed silica, 12-17 parts of diacetone alcohol, 1-1.5 parts of a dispersing agent and 0.5-1 part of a flatting agent. The flexible heat conduction paint has excellent heat conduction and heat absorption properties, good stability and high adhesive force and can be sprayed to a flexible base material and bent and folded along with the base material, when the paint is used for a heat insulation sunshading pad, rapid cooling and heat dissipation can be conducted on a target by means of the excellent heat absorption property, and therefore the cooling and heat preservation effects are achieved, and the heat insulation capacity of the heat insulation sunshading pad is obviously improved.

Description

Technical field [0001] The invention relates to the field of heat-insulating and heat-conducting materials, in particular to a flexible heat-conducting paint used for automobile heat insulation. Background technique [0002] As a tool for people’s outdoor activities, cars are very likely to be exposed to strong light from the outside world for a very long time. Especially with the advent of the hot summer, many people’s cars are parked in open-air parking lots. After exposure, when people return to their cars again When inside, the temperature inside the car was so high that people could not bear it. After an on-site test, on a sunny day in Chengdu, Sichuan Province, when the outside temperature was 32℃, the car without sunshade was parked in the open parking lot for 1 hour. , Use a thermometer to measure the temperature in the car. The test result is that the temperature in the cab in the car reaches 65°C, which is 33°C higher than the outside temperature. At this temperature, p...

Problems solved by technology

[0004] But existing automobile heat-insulating sunshade pads still have imperfections, that is to say, the existing heat-insulated sunshade pads realize heat insulation by blocking sunlight, often ignoring the heat absorption of the vehicle body itself, even if the car body The difference between the internal temperature and the outside temperature is 6°C, and the temperature difference of the metal body is at least 13°C, especially for the black paint body, the temperature difference can reach 20°C, there is still the possibility of burns, and the heat insulation effect needs to be improved
