Problems solved by technology

The organic heat insulation materials mainly include polystyrene and polyurethane. Although these materials have a small thermal conductivity, they have poor fire resistance, produce harmful gases at high temperatures, are easy to degrade and age, and have a short life. For example, the patent number is ZL200410013231.2 , the name of the invention is heat insulation, heat preservation, energy saving and waterproof paste and its preparation method. The polystyrene particles in the ingredients used have the above-mentioned shortcomings, so our country lacks effective heat insulation, energy saving, waterproof and excellent inorganic heat preservation materials.

Abstract

The invention relates to a nano-hydrophobic thermal insulation material and a preparation method thereof, which is prepared from component A and component B, wherein the main components of component A are calculated in parts by weight: high molecular polymer emulsion, modified Polypropylene fibers, nano-active calcium carbonate, and silicate minerals are mixed evenly and then grouped. The B component is cement. When in use, mix the A component and the B component in one group and mix well to obtain the nano-phobic Water-based thermal insulation material. The characteristics of the present invention are: the product of the present invention belongs to the inorganic thermal insulation material, which has long service life, aging resistance, good fireproof performance, the material itself has hydrophobic performance, the thermal conductivity of the material becomes smaller, the thermal insulation performance is better, and the compression resistance is better. Good strength and bonding strength, no cracking, no falling off, no pollution to the environment, good workability, easy construction, and short construction period.

Description

technical field [0001] The invention relates to a nano-hydrophobic thermal insulation material and a preparation method thereof, belonging to the technical field of building materials, and the product is used for thermal insulation and waterproofing of interior and exterior walls, roofs, basements and the like. Background technique [0002] In recent years, with the improvement of environmental protection and "green" engineering requirements, building energy conservation has become imminent. Building energy conservation has become the main content of the implementation of national environmental protection and energy conservation policies, and has become an important part of implementing the sustainable development of the national economy. The development of exterior wall insulation technology and the rational application of insulation wall materials are the main ways to achieve building energy conservation. Existing thermal insulation materials mainly include inorganic and o...
