Problems solved by technology

[0004] At present, in the method of preparing hydrophobic rock wool board, due to the uneven mixing of binder and water repellent, the cohesion of rock wool board is relatively poor. After a period of time, cracking and falling off will begin to occur, and the uneven mixing of water repellent will lead to the loss of waterproof performance of rock wool board, resulting in high water absorption

Embodiment

[0046] see Figure 1-7 , a preparation method of high-strength waterproof rock wool board, please refer to figure 1 , including the following steps:

[0047] S1, the rock is melted into a liquid at high temperature and then blown into rock wool fibers by a centrifuge. The thinner rock wool fibers are collected by the trapping belt, and then layer by layer with a pendulum;

[0048] S2. When stacking, first stack a certain thickness, then sprinkle the cohesive balls evenly on the rock wool fibers, and finally continue to stack until the rock wool fibers completely cover the cohesive balls;

[0049] S3, first compress the rock wool fibers in the above steps, and then put them into a mechanical vibration device in an uncured state, and change the distribution direction of the cotton layer by mechanical vibration.

[0050] see Figure 6-7 , the cohesive ball in step S2 includes a mother body 101 and a plurality of tentacles 102, and the plurality of tentacles 102 are fixedly con...

Abstract

The invention discloses a preparation method of a high-strength waterproof rock wool board, and belongs to the field of rock wool boards; a cohesion ball is creatively added in the process of producing the rock wool board by using the existing three-dimensional method to improve the cohesion of the rock wool board; on one hand, after the cohesion ball absorbs the heat of rock wool fibers, a pushing ball is expanded to push out a puncture rod, and the puncture rod penetrates through a plurality of layers of rock wool fibers to increase the cohesion of the rock wool fibers; on the other hand, the heat enables a heat shrinkage wrapping film to shrink so as to extrude a hydrophobic agent, the missing part can be filled with the hydrophobic agent to cover, the waterproof performance is effectively improved, the appearance of the cohesion ball is similar to the shape of octopus, a plurality of tentacles drag surrounding rock wool fibers, the strength of the rock wool board is effectively improved, and the rock wool board is prevented from cracking and falling off.

Description

technical field [0001] The invention relates to the field of rock wool boards, in particular to a method for preparing high-strength waterproof rock wool boards. Background technique [0002] Rock wool board is made of basalt and other natural ores as main raw materials, melted into fibers at high temperature, added an appropriate amount of binder, and solidified. It is widely used in shipbuilding, metallurgy, electric power, construction and other industries. Heat insulation and sound insulation effect. The construction and installation are convenient, the energy-saving effect is remarkable, and it has a high performance-price ratio. Hydrophobic additives are added to marine and hydrophobic rock wool insulation boards during production, which have good moisture-proof performance. Marine rock wool board is used for thermal insulation and fireproof partition of ships; hydrophobic rock wool board is used for vehicles, mobile equipment, cold storage projects, air conditioning...
