Abstract

Aiming at heat preservation and energy saving required in a plurality of occasions of industrial production and human life, the invention relates to a preparation method of a compound type heat preservation and insulation material, which includes taking inorganic fiber or inorganic fibrous composite or a vacuum insulation panel (VIP) as a heat insulation core and using glass fiber reinforced plastic or sheet metal and the like to cover the surface of the core. The heat preservation and insulation material is low water content, good in heat preservation, long in service life, convenient in use and low in cost, with the normal temperature coefficient of heat conductivity being less than 0.025W/m.k.

Description

Technical field: [0001] The invention relates to the preparation of a composite thermal insulation material. Background technique: [0002] Industrial production and people's life require heat preservation and energy saving in many places. Building thermal insulation materials are mainly expanded perlite, hollow glass beads, polystyrene board and other materials; pipeline insulation is mainly wrapped with rock wool, glass fiber, etc.; electrical products are mainly made of organic materials in-situ foaming or organic materials Two modes of in-situ foaming and adding inorganic powder. The effect of expanded perlite and hollow glass microspheres used in building energy saving is not satisfactory, and the service life of organic materials such as polyurethane foam (PUF), polystyrene foam (PSF), polyethylene foam (PET) is not satisfactory. Long, generally after 5 years, the thermal insulation performance will decline, and it is flammable, and the thermal conductivity is genera...
