Embodiment 1

[0041] Such as Figure 1-4 As shown, this embodiment provides a method for preparing foamed board filler, the cement used is P.042.5, including the following steps:

[0042] Step 1: Prepare waste paper granules; prepare waste paper into granules, and the treated waste paper is rich in short fibers, which disperse quickly and are not easy to agglomerate, leaving more gaps in the prepared filler. It has good air permeability, and can quickly discharge the water vapor in it during the drying process, reducing the drying time. At the same time, due to the dense presence of short fibers in the filler, the board made by the filler is not easy to produce Burst phenomenon.

[0043] Step 2: Prepare chaff granules; treat the chaff into granules, and the treated chaff is also rich in cellulose, lignin, and silica, which can further increase the fiber of the filler and the short fiber of waste paper Together, they can maintain the bulkiness of the filler to the greatest extent and impro...

Embodiment 2

[0062] As the preparation method of embodiment 1:

[0063] In step 4, waste paper particles, chaff particles and wollastonite powder are mixed in a weight ratio of 1.1:1.1:0.15.

[0064] In step 5, the concentration of the sodium hydroxide solution is 0.8mol / L, the reaction time is about 50min, the soaking temperature is about 85°C, and the weight ratio of the initial raw material to the sodium hydroxide solution is about 1.05:30.5.

[0065] In step 7, the weights of the fibrous raw material, slag powder and fly ash are respectively 65%, 30% and 20% of the weight of the cement.

[0066] In step 8, the weight of the water is 55% of the total water consumption.

[0067] In step 9, the weights of the sodium silicate, sodium carbonate, sodium sulfate, and hydrogen peroxide are respectively 1%, 1.8%, 1.8%, and 10.5% of the cement weight used in step 7, and the weight of the water is the total water consumption 45%.

[0068] Preferably, the weight of the total water consumption i...

Embodiment 3

[0071] As the preparation method of embodiment 2:

[0072] In step 4, waste paper particles, chaff particles and wollastonite powder are mixed in a weight ratio of 1:1:0.1.

[0073] In step 5, the concentration of the sodium hydroxide solution is 0.8mol / L, the reaction time is about 45min, the soaking temperature is about 80°C, and the weight ratio of the initial raw material to the sodium hydroxide solution is about 1:30.

[0074] In step 7, the weights of the fibrous raw material, slag powder, and fly ash are respectively 58%, 27%, and 18% of the weight of the cement.

[0075] In step 8, the weight of the water is about 50% of the total water consumption.

[0076] In step 9, the weights of the sodium silicate, sodium carbonate, sodium sulfate, and hydrogen peroxide are respectively 0.8%, 1.6%, 1.6%, and 10% of the cement weight used in step 7, and the weight of the water is the total water consumption 50% of.

[0077] Preferably, the weight of the total water consumption ...

Abstract

The invention relates to preparation methods of materials used in the building field, in particular to a preparation method of foamed sheet filler. Waste paper and chaff are used as raw materials, short fibers in the waste paper and chaff and lignin in the chaff are extracted, and the obtained filler is light in mass, good in breathability and free of a rupture phenomenon. In addition, after wollastonite is added, the impact resistance, the anti-bending strength and abrasive resistance of prepared sheets can be greatly improved, and resources are saved. No environmental pollution can be caused after sheets made through the preparation method are abandoned. The preparation method has high practical value.

Description

technical field [0001] The invention relates to a preparation method of materials used in the construction field, in particular to a preparation method of a foamed board filler. Background technique [0002] Foamed boards are generally used for building wall decoration or as thermal insulation boards. Common foamed boards are generally made of chemical materials such as polyvinyl chloride, which not only consumes resources, but also easily causes environmental pollution. At present, there are also thinner ones. The technical solution for the preparation of the foamed board is realized by filling fillers between the boards, which not only ensures the overall appearance of the foamed board, but also uses the filler to enhance the compressive and flexural strength of the foamed board, and has a wider range of use. However, the currently used foam board fillers are generally made of chemical raw materials, and the preparation process needs to consume more resources. In particula...
