Thermal insulation energy-saving composite material and preparing method thereof

Abstract

The invention relates to a heat-insulation and energy-saving compound material and a preparation method thereof, comprising the following components in portions by weight: 20-45 portions of floating beads, 30-65 portions of core-shell polymeric polymerized emulsion, 20-50 portions of nano oxide, 6-40 portions of fillers, 1-10 portions of antimicrobial powders, 1-5 portions of additives and the residue is water. The steps of the preparation method of the compound material are: firstly, the core-shell polymeric polymerized emulsion is mixed with antifreeze agent and film forming additive to obtain (I); the fillers and the antimicrobial powders are mixed uniformly with dispersant / wetting agent, defoamer, the antifreeze agent, hydrophobic agent and the nano oxide to obtain (II); the (I) and the (II) are mixed uniformly before the floating beads are added; the pH value is adjusted to 7.8-8.3; the mixture obtained is filtered, thus gaining a finished product. The compound material has multiple effects such as heat insulation, thermal insulation, energy saving, ultraviolet light resistance and impact resistance.

Description

Energy-saving composite material for heat insulation and heat preservation and preparation method thereof technical field The invention relates to an energy-saving composite coating for thermal insulation and its preparation method, especially a new type of coating and its preparation method integrating multiple functions such as thermal insulation, thermal insulation, waterproofing, and energy saving, which belong to inorganic-organic nanocomposite materials field. Background technique Taking the existing various exterior walls as an example, their functions are single. Even the ICI coatings that are popular in the market for a while have very single performance, especially for heat insulation, heat preservation, waterproof, elastic self-healing, and crack resistance. There are few reports on wall materials integrating energy saving. For example, the "new heat insulation, heat insulation coating and production technology" (CN90105780.0) proposed by Gou Xiaohui of Chongqin...
