Problems solved by technology

At present, the most commonly used method is to wrap a layer of gel sheet on the surface of polyurethane sponge, but there is also a fatal shortcoming of slow heat release, which leads to slow heat release once the heat absorption is saturated, and finally the surface temperature of the sponge is difficult to drop

Embodiment

[0024] The following raw materials are selected to prepare a novel composite cool-feel coating, and the composite cool-feel coatings in each embodiment are prepared from the following raw materials in parts by mass:

[0025] . The composite cooling coatings of the above-mentioned embodiments can be applied by mechanical roller coating. The production process is as follows: each component is placed in the cylinder of the metering pump, and enters the mixing chamber in proportion through the metering pump. After mixing, it enters the material tank of the adjacent roller through the pipeline, and the thickness of the roller coating is controlled by adjusting the distance between the rollers. After drying at room temperature, a thin and cool coating is obtained.

[0026] The composite cooling coating prepared in Examples 1-7 is subjected to performance testing, and it can be found by comparing examples 1, 2, and 3 that as the amount of modified MDI increases, the tactile hardnes...

Abstract

The invention relates to a composite type cool feeling coating. The composite cool feeling coating consists of the following components in parts by weight taking 100 parts of polyether polyol as accounts, 20 to 50 parts of modified MDI, 40 to 60 parts of phase-change material particles, 0.1 to 0.2 part of color paste, 5 to 10 parts of diluent and 0.5 to 2 parts of water. The composite type coolingcoating has the advantages that the composite type cooling coating disclosed by the invention adopts the particles with phase-change performance; after adding a phase-change material, the material becomes viscous so adopting the diluent to carry out viscosity reduction processing; meanwhile, a small volume of added water can carry out a rapid and little foaming reaction with a isocyanate group inthe material, and then the material can carry out better cross linking action with the polyether polyol; the composite type cool feeling coating prepared by the formula has a good heat-conducting property, can carry out absorption and release of heat better, reinforces cooling and comfortable degrees on the surface of sponge, reduces the surface temperature and can enable a user to have the unique experience of feeling warm in winter and cool in summer.

Description

technical field [0001] The invention belongs to the technical field of preparation of cool-feeling coatings, in particular to a composite cool-feeling coating. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, people have fundamentally changed the functionality and comfort of polyurethane sponges, gradually changing from the past economical practicality to comfort and functionality as the main considerations. factor. At present, the most commonly used method is to wrap a layer of gel sheet on the surface of polyurethane sponge, but there is also a fatal shortcoming of slow heat release, which leads to slow heat release once the heat absorption is saturated, and finally the surface temperature of the sponge is difficult to drop. [0003] In hot summer conditions, in order to better absorb and release heat, enhance the coolness and comfort on the surface of the sponge, and reduce the...
