Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a molding and processing method of a modified cement foam insulation board. Background Art

[0002] In the field of building materials technology, building materials engineering technology plays a vital role. It is not only related to the appearance, quality and safety of the building, but also to the environmental protection of the building. High-performance insulation materials have been widely used in the field of building energy conservation in recent years. Cement foam insulation board, as a lightweight, heat-insulating and sound-insulating building material, is widely used in building exterior wall insulation systems.

[0003] However, traditional cement foam insulation boards have problems such as low strength, easy cracking and high water absorption, which affect their service life and thermal insulation performance. In order to solve these problems, the prior art usually improves the performance of cement foam insulation boards by adding admixtures or modified materials, but there are still problems such as complex process, high cost and limited performance improvement.

[0004] Therefore, we propose a molding and processing method of modified cement foam insulation board. Summary of the invention

[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a forming and processing method of a modified cement foam insulation board.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme, a method for forming a modified cement foam insulation board, which specifically comprises the following steps:

[0007] Step 1: Raw material preparation: Accurately weigh the appropriate amount of cement, fly ash, silica fume, foaming agent, first modifier, second modifier and water according to the formula to ensure that the proportion of each raw material is accurate;

[0008] Step 2: Mixing and stirring: Put the cement, fly ash, silica fume, first modifier and second modifier prepared in the first step into the mixing equipment in proportion, dry mix for 2-3 minutes, then add the foaming agent and water, and continue to stir for 3-5 minutes until a uniform foaming slurry is formed. After the stirring is completed, the foaming slurry is quality inspected to ensure that it meets the production requirements and is ready for the subsequent foaming molding step;

[0009] Step 3: Foaming: The foaming slurry stirred evenly in the second step is fed into the mold of the foaming molding equipment. The inner wall of the mold is pre-coated with a release agent. The foaming is carried out at room temperature for 10-20 minutes. The foaming height reaches 80%-90% of the mold height. After the foaming is completed, the foam is cut and trimmed to obtain a modified cement foam insulation board prototype that meets the requirements.

[0010] Step 4: Curing: The modified cement foam insulation board prototype obtained by foaming in the third step is sent to the curing room for curing. The curing temperature is controlled at 40-60°C, the relative humidity is 70%-90%, and the curing time is 24-48 hours. After the curing, the board is demoulded to obtain the initially formed cement foam insulation board. During the curing process, the state of the insulation board needs to be checked regularly to ensure that it has no cracks, deformations and defects. After the curing is completed, the insulation board has good physical properties and thermal insulation performance, which lays the foundation for the subsequent post-processing steps.

[0011] Step 5: Post-processing: The insulation board after curing treatment is further processed. First, the surface of the insulation board is polished and trimmed to remove burrs and uneven parts on the surface to make it smoother and flatter and improve its aesthetics. Then, according to customer needs, waterproof, fireproof and decorative coatings can be applied on the surface of the insulation board to enhance its waterproof and fireproof properties and give it a specific decorative effect. Finally, the insulation board is quality inspected and packaged to ensure that it meets relevant standards and customer requirements, and then stored and shipped.

[0012] Preferably, the weight ratios of cement, fly ash, silica fume, foaming agent, first modifier, second modifier and water in the first step are: (50-70):(10-20):(5-10):(0.5-2):(1-3):(0.1-0.5):(20-30).

[0013] Preferably, the cement in the first step is ordinary Portland cement or sulphoaluminate cement.

[0014] Preferably, the particle size of the fly ash in the first step is 200 mesh-400 mesh.

[0015] Preferably, the particle size of the silica fume in the first step is 100 mesh-300 mesh.

[0016] Preferably, the foaming agent in the first step is a protein foaming agent or a chemical foaming agent.

[0017] Preferably, the first modifier in the first step is nano-silicon dioxide.

[0018] Preferably, the second modifier in the first step is polypropylene fiber.

[0019] The present invention provides a method for forming and processing a modified cement foam insulation board, which has the following beneficial effects:

[0020] 1. This modified cement foam insulation board molding and processing method effectively improves the strength and thermal insulation performance of the cement foam insulation board by accurately controlling the raw material ratio and process steps, while reducing the water absorption rate and extending the service life. It has the advantages of simple process, low cost and excellent performance, can be widely used in the fields of building exterior wall insulation systems, and has high market value and application prospects.

[0021] 2. A forming and processing method for a modified cement foam insulation board comprises adding nano-silicon dioxide and polypropylene fiber as modifiers to the raw materials. Nano-silicon dioxide can fill the gaps between cement particles and improve the density and strength of the material, while polypropylene fiber can enhance the toughness and crack resistance of the material. The two work together to make the prepared cement foam insulation board have more excellent physical properties and thermal insulation properties.

[0022] 3. The modified cement foam insulation board forming and processing method controls the foaming time and the foaming height so that the prepared cement foam insulation board has a uniform pore structure and good thermal insulation and sound insulation effects.

[0023] 4. The modified cement foam insulation board forming and processing method controls the curing temperature, relative humidity and curing time so that the cement hydration reaction can proceed fully, thereby improving the strength and durability of the insulation board.

[0024] 5. This modified cement foam insulation board forming and processing method improves the appearance and practicality of the insulation board through processing such as grinding, trimming and painting, and meets the needs of different customers. BRIEF DESCRIPTION OF THE DRAWINGS
