preparation example Construction

[0023] The preparation method of polyphenylene mortar in the present invention comprises: 26~68g of rubber powder, 56~105g of polyphenylene particles, 3~8g of aluminum silicate, 2~10g of vitrified microbeads, 12~24g of water reducer, 12g of gypsum ~22g, fly ash 10~16g and water 100~266g.

[0024] Its concrete preparation process is:

[0025] 1) Preparation of modified polyphenylene particles: Mix aluminum silicate and vitrified microbeads to form a solution, spray the mixed solution on the surface of polyphenylene particles, and then add fly ash to mix evenly;

[0026] 2) Preparation of modified rubber powder: Mix rubber powder and vitrified microbeads, then add gypsum and stir evenly;

[0027] 3) Add water reducing agent, gypsum, fly ash and water to the modified polystyrene particles and modified rubber powder, and then fully and uniformly stir at 40~65°C to obtain polyphenylene mortar.

[0028] Vitrified microspheres can be used as a compacting regulator for thermal insul...

Abstract

The invention discloses a polyphenyl mortar insulation board and a preparation method of polyphenyl mortar. The polyphenyl mortar insulation board comprises a foundation wall, an insulating layer, a noise absorbing layer and a decorative finish layer, wherein the insulating layer comprises a first polyphenyl mortar board and a second polyphenyl mortar board, alkali-resisting glass fiber gridding cloth is arranged between the first polyphenyl mortar board and the second polyphenyl mortar board, the noise absorbing layer adheres to the insulating layer through a binding agent, and the decorative finish layer adheres to the noise absorbing layer through the binding agent. The preparation method of the polyphenyl mortar comprises the following steps that modified polyphenyl particles are prepared and modified rubber powder is prepared, a water reducing agent, gypsum, coal ash and water are then added to the modified polyphenyl particles and the modified rubber powder, and all the materials are fully and evenly mixed at the temperature of 40-65 DEG C. The polyphenyl mortar insulation board and the preparation method of the polyphenyl mortar have the advantages that the shearing-strength resistance of the polyphenyl mortar boards can be reduced, good weather ability and good fire resistance are guaranteed, the strength of an insulating board is enhanced, the noise absorbing rate is effectively improved in the building environment, and the compact performance and the compaction degree of the insulating mortar are improved.

Description

technical field [0001] The invention relates to the field of building insulation boards, in particular to a polyphenylene mortar insulation board and a preparation method of the polystyrene mortar. Background technique [0002] In recent years, with the rapid development of social economy, the construction industry has also been more and more extensive development and progress. The insulation of exterior walls in construction production is an important step in the construction industry, and it is also a link with a large investment. The excellent insulation performance of exterior walls is closely related to the service life of buildings. [0003] In the prior art, thermal insulation mortar boards are generally used, but their shear resistance is not good, and the compactness of the thermal insulation mortar is not good. At the same time, the thermal insulation mortar boards cannot resist noise well, which affects the surrounding environment. Contents of the invention [...
