Abstract

The invention relates to a nano silicon-based composite heat insulation tile shell and a preparation method thereof, and belongs to the field of heat preservation tile shells. In order to overcome theshortcomings of high heat conduction coefficient, brittleness and frangibility of the existing tile shell, the nano silicon-based composite heat insulation tile shell is prepared from the following raw materials in parts by weight: 15 to 20 parts of fiber cotton, 120 to 180 parts of glass beads, 5 to 10 parts of floating beads, 5 to 10 parts of attapulgite hydrosol and 5 to 8 parts of silica hydrosol. By adoption of the fiber cotton, the nano silicon-based composite heat insulation tile shell disclosed by the invention has tensile strength and compressive strength, is light in weight, low inheat conduction system, high in toughness, difficult to break and long in service life.

Description

technical field [0001] The invention relates to a tile shell and a preparation method thereof, in particular to a nano-silicon-based composite heat-insulating tile shell and a preparation method thereof, belonging to the field of thermal insulation tile shells. Background technique [0002] At present, the tile shells for high-temperature pipeline insulation are generally made of perlite, silicate, calcium silicate or microporous calcium silicate tile shells. The main materials of this type of tile shells are pressed from perlite and calcium silicate plus water glass glue. , so the thermal conductivity is high, the texture is brittle, fragile, and the service life is short. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high thermal conductivity, brittle texture and fragility of existing tile shells, and provide a nano-silicon-based composite heat-insulating tile shell with low thermal conductivity, high toughness, non-b...
