Abstract

The invention relates to a preparing method of a novel building energy-saving and heat-preserving material. The preparing method includes the following steps that 1, flyash, expanded perlite, fiber, silicate, sulfonated acetone formaldehyde and a silane coupling agent are put into a stirrer, mixed and stirred uniformly to obtain a first mixture; 2, distilled water is added into the first mixture and mixed through the stirrer to obtain a second mixture; 3, the second mixture is poured into a mold and formed in a compression mode through a compression forming device; 4, the surface of the formed material is calendered, after a calendering layer is fully dried, a curing agent is smeared on the surface of the calendering layer, and the finished product can be obtained after the curing agent layer is fully dried. The energy-saving and heat-preserving material is suitable for the wall building field and has the advantages of being waterproof, fireproof, corrosion resistant, high in strength, long in service life, high in density and compressive strength, low in heat conductivity and good in heat preserving effect.

Description

technical field [0001] The invention belongs to the technical field of building thermal insulation materials, and in particular relates to a preparation method of a novel building energy-saving thermal insulation material. Background technique [0002] The advent of the energy crisis in the century and the mandatory implementation of building energy-saving policies have promoted the rapid development of building insulation materials. [0003] Most of the current thermal insulation materials use ordinary expanded perlite and polystyrene particles as lightweight aggregates for dry-mixed thermal insulation mortars, but expanded perlite has high water absorption and is easy to pulverize, and its volume shrinkage rate is large during slurry mixing, which is easy to cause product damage. Low strength and hollowing and cracking in the later stage, while polyphenylene particle organic materials have defects such as flammability, poor fire resistance, harmful gases generated at high ...
