Embodiment 1

[0065] 1) Surface modification of polystyrene particles

[0066] Bulk density 9kg / m 3 1000 liters of primary polyphenylene particles, 15kg of adhesive, 0.6kg of coupling agent, 8kg of water, and 110kg of cement; first dilute the adhesive with water, then add polyphenylene particles and silane coupling agent, stir, and wait until the surface of polyphenylene particles After being completely wetted, add cement and stir to coat the surface of the particles with a layer of cement paste.

[0067] 2) Preparation of additives for foamed cement insulation board:

[0068] 10 parts of calcium stearate;

[0069] 6 parts of Illite;

[0070] 1 part of sodium carboxymethyl cellulose;

[0071] 18 parts of calcium nitrate;

[0072] 8 parts of gypsum;

[0073] 20 parts of sodium chloride;

[0074] 19 parts of lithium carbonate;

[0075] 1 part of triethanolamine;

[0076] 6 parts quicklime;

[0077] Shrinkage reducer 3 parts.

[0078] 3) Preparation of foamed cement insulation board b...

Abstract

The invention discloses a method for manufacturing a foamed cement insulation board added with polyphenylene particles. Polyphenylene particles, cement, adhesives, coupling agents, and water are used to modify the surface of polyphenylene particles. Form a layer of silicate shell; then prepare additives for foamed cement insulation boards, add water, water reducing agent, PP fiber 0, additives for foamed cement insulation boards, modified polystyrene Granules 1. Portland cement, fly ash, stir to mix evenly, and finally add 10-12 kg of hydrogen peroxide and stir to mix evenly; after hydration, demoulding, maintenance, and cutting. Compared with ordinary foamed cement insulation boards, the foamed cement insulation board made by the manufacturing method proposed by the present invention has reduced bulk density, increased flexural strength, and reduced thermal conductivity, which can reduce the thermal conductivity of foamed cement insulation boards under the same conditions. Use thickness.

Description

technical field [0001] The invention relates to the production of a foamed cement insulation board, in particular to a production method of the foamed cement insulation board added with polyphenylene particles. Background technique [0002] Foamed cement insulation board is a class A fireproof insulation material, which has the advantages of light weight, high strength and good durability. However, the biggest disadvantage of foamed cement insulation board is its large bulk density, high brittleness, and high thermal conductivity, resulting in bulky volume. , easy to damage when handling, and cannot be used in severe cold or cold areas. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a method for making a foamed cement insulation board added with polyphenylene particles, which reduces thermal conductivity and improves physical and mechanical properties. [0004] In order to solve the problem...
