Similar waterproofing treatment is also adopted for the waterproofing of lightweight cement boards, however, mixing the waterproofing agent directly with other raw materials will affect the strength of cement boards
On the other hand, lightweight boards generally include foamed cement boards and lightweight material-filled cement boards. Foamed cement boards inevitably have cavities when cutting, which affects the hydrophobic effect; although the surface of lightweight material-filled cement boards is flat, they can not be cut. , but light materials are usually porous, and small voids appear after being worn, which affects the hydrophobic effect of the sheet

[0044] The preparation method of the above-mentioned high-strength and light-weight water-repellent cement board comprises the following steps:
[0045] (1) Preparation of hydrophobic granular material: Mix quartz particles A, hydrophobic agent, coupling agent and water evenly, then dry to obtain modified quartz particles, mix cement and water to make cement mixture, and mix with cement Add modified quartz particles into the material and mix evenly to make hydrophobic particles;
[0046] (2) Preparation of lightweight granules: after mixing cement and water evenly, adding perlite, microbeads and quartz particles B, and mixing evenly to make lightweight granules;
[0047] (3) Cloth: apply a layer of hydrophobic granules in the mold, lay an interlayer on the surface of the hydrophobic granules, place a layer of lightweight granules on the interlayer, and lay a barrier on the surface of the lightweight granules. Then apply a layer of hydrophobic granules on the interlayer;

Abstract
The invention discloses a high-strength and lightweight hydrophobic cement board and a preparation method thereof. The cement board comprises a hydrophobic layer, a lightweight layer and an interlayer for separating the hydrophobic layer and the lightweight layer. The hydrophobic layer is the surface layer of the hydrophobic cement board; the raw materials of the hydrophobic layer include cement, quartz particles A, water repellent and coupling agent, and the quartz particles A are made by modifying the water repellent and coupling agent Modified quartz particles, the raw materials of the light layer include cement, perlite, microbeads and quartz particles B. The preparation method includes steps (1)-(4). The cement board of the invention has better hydrophobic effect and better strength. The method of the invention can be mass-produced to obtain cement boards with good hydrophobic effect and high strength.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength and light-weight water-repellent cement board and a preparation method thereof. Background technique [0002] Cement board is a commonly used building material. Traditional cement board is usually made of cement and quartz sand, which has a high water absorption rate and affects durability. The current solution to this problem is to add a waterproofing agent to the formula, usually by directly mixing the waterproofing agent with other raw materials, that is, adding all the raw materials of the cement board to the container at the same time and mixing evenly, then distributing in the mold and vibrating to form, and then curing to obtain the finished product . Similar waterproofing treatment is applied to the waterproofness of lightweight cement board, however, mixing the waterproofing agent directly with other raw materials will affect the strength of t...
