Hollow microbead three-dimensional matrix laminate for heat insulation, sound insulation, self-cleaning, sterilization and air cleaning

Abstract

A hollow microbead three-dimensional matrix laminate for heat insulation, sound insulation, self-cleaning, sterilization and air cleaning is characterized in that a substrate is coated with a hollow microbead three-dimensional matrix layer, the hollow microbead three-dimensional matrix layer is a multi-layer closely-arranged hollow microbead matrix, and the surface layer of the hollow microbead three-dimensional matrix layer is coated with a titanium dioxide anti-radiation film. A thin novel hollow microbead three-dimensional matrix laminate for heat insulation, sound insulation, self-cleaning, sterilization and air cleaning is used for replacing curved plates of shells of foam (rock wool) color steel flat plates, airplanes, trains and the like with certain thicknesses, the problems that foam and rock wool plates are thick, heavy, inflammable, polluted and high in cost are solved, and living space is healthier.

Description

technical field [0001] The invention relates to a new type of board. Background technique [0002] At present, the flat panels of color steel roof walls in urban and rural areas, as well as curved panels such as aircraft shells, train shells, car shells, boat shells, and oil tanks, are all glued to the inner wall or outer wall to solve the problem of sun protection in hot weather and cold weather insulation. Foaming material or rock wool, the surface of foaming material or rock wool should be glued with a layer of fireproof and scratch-resistant material. Water absorption reduces the thermal insulation effect, and due to its open-cell fiber structure, it needs to be thicker to achieve the thermal insulation effect of closed-cell foam materials. Once rock wool is discarded as construction waste and spreads with the wind, the disaster will be far greater than a plague: Once the rock wool fiber is inhaled into the alveoli, it will be stuck there forever, and there is no way to...

Problems solved by technology

In order to solve the problem of lack of beads and cumbersome process caused by the current hollow microbead heat insulation coating process, I invented a "hollow microbead matrix layer adhesion coating method" (Chinese patent application number: 2020101727663), and its process flow is: (1) First coat the viscous paint on the surface of the substrate, (2) Then spray hollow microbeads on the surface when the paint is not dry and sticky, and use the viscosity of the paint to make the surface of the substrate evenly covered with a layer of hollow microbeads, that is, hollow microbeads Bead matrix layer, (3) after the coating is dried (or dried), the substrate surface coating coating of the hollow microspheres has been applied, and then the hollow microspheres are sprayed on the surface when the coating is not dry and sticky, and the coating is utilized Viscosity makes the surface of the substrate evenly covered with a layer of hollow microbeads, repeating this process repeatedly to achieve the expected number of hollow bead matrix layers, thus forming a multilayer hollow bead matrix layer with densely arranged hollow microbeads, that is, hollow microbeads Bead three-dimensional matrix layer
