Problems solved by technology

[0004] Due to the existence of the foaming agent, there are a large number of holes inside the insulation board when the insulation board is prepared. These holes not only play a role in heat insulation, but also have a certain sound insulation, but the sound insulation effect of only a single hole is poor and cannot Meet noise reduction requirements
[0005] In addition, although these holes can be used for heat insulation and reduce the quality of the insulation board, it is difficult to control the uniformity of the distribution of the holes after the foaming agent foams the cement, making the insulation effect uneven, and the holes generated by the foaming will cause The overall strength of the insulation board is low, and the uneven size and distribution of the holes will also make the strength of each part of the insulation board uneven, making it easier to break

Abstract

The invention relates to the field of heat-insulating board making and discloses a making method of a noise-reducing heat-insulating board. The making method includes: A), well stirring silicate cement, fly ash, bamboo wood powder, butyl rubber particles, diatomite, shell powder, hollow glass beads, sepiolite, organic-inorganic composite heat-storage particles, bagasse fiber and mineral wool fiber to obtain a solid component; B), adding carboxymethylcellulose, sodium alginate and sodium dodecyl benzene sulfonate into water, and stirring well to obtain a liquid component; C), mixing the solid component with the liquid component for heating while stirring to obtain pouring size; D), pouring the pouring size into a mould, and obtaining a finished product through forming solidification, demoulding, maintaining and drying. The heat-insulating board made by the method is light in mass and high in pore size and distribution uniformity and has excellent noise-reducing effect on the basis of good heat-insulating effect and high strength.

Description

technical field [0001] The invention relates to the field of heat preservation board preparation, in particular to a preparation method of a noise reduction heat preservation 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 paraffin wax 5...
