Method for preparing assembled integrated boards

Abstract

The invention discloses a method for preparing assembled integrated boards. The method comprises the following steps: first weighing the following raw materials in parts by weight: 15~25 parts of geopolymer cement, 15~35 parts of light ceramsite, 45~53 parts of modified mortar and 2~5 parts of straw fiber, then performing dry mixing on the raw materials in a stirrer for 2~8 minutes to obtain a rawmaterial mixture, weighing a certain amount of tap water, adding an additive to the tap water, then adding the tap water mixed with the additive to the raw material mixture, stirring for 3~8 minutesto obtain a slurry, pouring the slurry into a steel mold coated with an alkali-resistant plastic mesh cloth, placing polyethylene sheet with thickness of 70 mm and steel wire mesh sheets with thickness of 2 mm on both sides when the slurry is evenly spread to a thickness of 25 mm, pouring the slurry, adding a layer of the alkali-resistant plastic mesh cloth to the slurry when the thickness of theslurry reaches 25 mm, shaking and compacting with a vibrator, smoothing, demolding after 60~90 minutes, and natural curing for 7~10 days. The method replaces polystyrene particles with light inorganicceramsite to increase straw fiber and improve the tensile strength and impact resistance of the board, and the board has the characteristics of cracking resistance, environmental friendliness and soon.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a method for preparing an assembled integrated panel. Background technique [0002] Prefabricated building is a new type of energy-saving and environmentally friendly building. In addition to energy-saving design, energy-saving wall materials are also a key to the success of prefabricated buildings. Therefore, in the production of wall materials, some insulation materials are usually added, such as rock wool, calcium carbonate or gypsum to achieve light weight. However, these thermal insulation fiber materials have some inherent deficiencies, such as: rock wool insulation boards are light and sound-absorbing, but they contain moldy plant starch or formaldehyde carcinogens, which seriously damage human health; calcium carbonate or gypsum boards are fire-resistant The flammability is good, but the sound absorption and heat insulation effect is not good.

Problems solved by technology

Although the prepared composite expanded perlite integrated insulation board can solve the easy damage phenomenon of the expanded perlite board itself, the production process is complicated and the production cost is high

[0006] To sum up, how to overcome the shortcomings of low tensile strength and easy cracking of existing insulation boards, and provide a simple and quick production method is an important task in the implementation of prefabricated buildings.
