Problems solved by technology

[0004] However, the thermal insulation board of the above invention is the same as the traditional cement foam thermal insulation board. Due to the presence of the foaming agent, there are a large number of holes inside the thermal insulation board when the thermal insulation board is prepared. Although these holes can be used for heat insulation, and reduce the quality of the thermal insulation board , but after the foaming agent makes the cement foam, it is difficult to control the uniformity of the distribution of the pores, which makes the thermal insulation effect uneven. It will make the strength of each part of the insulation board uneven and more likely to break

Abstract

The invention relates to the field of preparation of insulation boards, and discloses a preparation method of a high-strength compound cement-based insulation board. The method comprises the following steps: A) Portland cement, coal ash, diatomite, shell powder, hollow glass beads, sepiolite, organic and inorganic compound heat storage particles, bagasse fiber and mineral wool fiber are uniformly stirred, and a solid component is prepared; B) carboxymethyl cellulose, sodium alginate, and sodium dodecyl benzene sulfonate are added into water with uniformly stirring, and a liquid component is prepared; C) the solid component and the liquid component are mixed and heated with stirring, and cast slurry is prepared; D) the cast slurry is cast into a die, moulding and solidification, demoulding, maintenance and drying are carried out, and a finished product is prepared. A cement foaming agent is used, and the prepared insulation board has the advantages of light weight, good uniformity of hole dimension and distribution, good insulation effects, and high strength.

Description

technical field [0001] The invention relates to the field of insulation board preparation, in particular to a preparation method of a high-strength composite cement-based insulation board. Background technique [0002] Cement foam insulation board is an insulation board made of foamed cement as the main raw material. The traditional cement foam insulation board is made by mixing and foaming cement, hydrogen peroxide, hard calcium, fly ash and cement foaming agent. Its thermal conductivity is low and it has good thermal insulation effect, so it is an ideal wall thermal insulation material. [0003] The authorized announcement number is CN103449834B, and the Chinese invention patent whose authorization date is 2015.07.01 discloses a foamed foam insulation board and its preparation method. The insulation board is composed of the following raw materials in parts by weight: ordinary portland cement 90-100 , fly ash 70-80, nano-bentonite 10-20, nano-silica 3-5, emulsified paraffi...
