Manufacturing method of foam cement insulation board added with polyphenyl granules

Abstract

The invention discloses a manufacturing method of a foam cement insulation board added with polyphenyl granules, which comprises the following steps: performing modification treatment on the surfaces of the polyphenyl granules by using the polyphenyl granules, cement, adhesive, coupling agent and water, thus forming a layer of silicate shell on the surface of each polyphenyl granule; preparing adjuvant for the foam cement insulation board; adding water, water reducer, PP fiber 0, the adjuvant for the foam cement insulation board, modified polyphenyl granules 1, silicate cement and pulverized coal ash into a stirrer, stirring for mixing uniformly, finally adding 10-12 kg of hydrogen peroxide and stirring for mixing uniformly; demolding, curing and cutting after being hydrated. Compared with a common foam cement insulation board, the foam cement insulation board manufactured according to the method provided by the invention has the advantages that the unit weight is reduced, the breaking strength is increased, the heat conduction coefficient is reduced, and the use thickness of the foam cement insulation board is reduced under the same condition.

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 pro...
