Abstract

The invention discloses a novel thermal insulation material preparation method. The method comprises the following steps that (1) phosphate, expand perlite, fiber, silicate, a water repellent and a penetrant are put into a blender for mixing and blending evenly, and a first mixture is obtained; (2) the first mixture continues to be blended by the blender for 40-60 min after distilled water is added, and a second mixture is obtained; (3) the second mixture is poured into a mold for compression molding by a compression molding machine, and is subjected to natural caring for 2-3 days; (4) calendaring processing is conducted on the surface of molded material, after a calendaring layer is completely dried, a layer of curing agent is smeared on the surface of the calendaring layer, and a finished product can be obtained after the curing agent layer is dried completely. Thermal insulation material is applicable to the field of architecture, which has the advantages of waterproofing, fireproofing, corrosion resistance, high strength and long service life, the thermal insulation material is large in density, high in compressive strength and low in heat conductivity coefficient in addition, thereby making a good effect on thermal insulation, and moreover, the preparation method is simple and the cost is low, which make the thermal insulation material suitable for industrialized mass production.

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 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 temperature, low aging ...
