preparation example Construction

[0014] The invention provides a method for preparing a highly cohesive aerated concrete block binder, wherein the preparation method comprises:

[0015] (1) mixing epoxy resin and silicon dioxide to obtain mixture M1;

[0016] (2) mixing the mixture M1, cement, fly ash, sand, calcium oxide and acrylate to obtain a highly cohesive aerated concrete block binder; wherein,

[0017] Relative to 100 parts by weight of the cement, the amount of the fly ash is 10-100 parts by weight, the amount of the epoxy resin is 5-50 parts by weight, and the amount of the silica is 1-10 parts by weight The amount of sand used is 5-70 parts by weight, the amount of calcium oxide used is 1-30 parts by weight, and the amount of acrylate is 1-30 parts by weight.

[0018] In the above design, the epoxy resin is modified by silica, and then mixed with cement, fly ash, sand, calcium oxide and acrylate, so that the prepared aerated concrete block has good bonding performance, so that It can have better ...

Embodiment 1

[0029] Mix 10g of epoxy resin and 3g of silica at 50°C to obtain mixture M1; grind cement, fly ash, sand and calcium oxide to a particle size of 1mm, and mix 100g of the above-prepared mixture M1 Cement, 30g of fly ash, 20g of sand, 5g of calcium oxide and 5g of acrylate were mixed to obtain the highly cohesive aerated concrete block binder A1.

Abstract

The invention discloses a high-viscosity aerated concrete block binder as well as a preparation method and an application thereof. The preparation method comprises the following steps: (1) mixing epoxy resin with silicon dioxide to obtain a mixture M1; (2) mixing the mixture M1, cement, coal ash, sand, calcium oxide and acrylate to obtain the high-viscosity aerated concrete block binder, wherein the high-viscosity aerated concrete block binder comprises the following raw materials in parts by weight: 100 parts of the cement, 10-100 parts of the coal ash, 5-50 parts of the epoxy resin, 1-10 parts of silicon dioxide, 5-70 parts of the sand, 1-30 parts of calcium oxide and 1-30 parts of acrylate. With the design, the high-viscosity aerated concrete block binder can have relatively good binding property in an actual using process, so that the application range of the high-viscosity aerated concrete block binder is greatly expanded and the use performance of the high-viscosity aerated concrete block binder is improved.

Description

technical field [0001] The invention relates to the field of production and manufacture of an aerated concrete block binder, in particular to a highly cohesive aerated concrete block binder and a preparation method and application thereof. Background technique [0002] Air-entrained concrete blocks are widely used in daily life, and aerated concrete blocks need to be bonded with binders in the actual use process. Therefore, the effect of binders will greatly determine Buildings constructed of aerated concrete blocks. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a highly cohesive aerated concrete block binder with high cohesive performance and better application effect and its preparation method. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem that the adhesive performance of the aerated concrete block adhesive in the prior art is gen...
