preparation example Construction

[0053] In addition, the present invention also provides a method for preparing the above-mentioned hydrophobic particles, the method comprising the following steps:

[0054] Step 1: heating the aggregate to 50-400°C;

[0055] Step 2: Add hydrophobic resin and stir evenly to coat the aggregate surface;

[0056] Step 3: cooling, crushing and sieving to obtain hydrophobic particles.

[0057] Wherein, in step 1, the aggregate preferably has a particle size of 6-300 mesh quartz sand, slag, ceramsite and glass beads, more preferably 100-200 mesh quartz sand. In addition, the heating temperature is preferably from 100 to 240°C.

[0058] In the step 2, the addition amount of the hydrophobic resin accounts for 1-8% of the mass of the aggregate. Moreover, the hydrophobic resin is selected from one or more of hydrophobic epoxy resins, phenolic resins, polyurethane resins, and silicone resins. Preferably, the hydrophobic epoxy resin is glycidyl ether epoxy resin, glycidyl ester epoxy ...

Embodiment 1

[0072] Select 100 grams of 6-mesh quartz sand particles, heat to 50 ° C, then add 6 grams of liquid polyvinyl alcohol tert-butyraldehyde modified epoxy resin, stir well, then add 1 gram of polyamide curing agent, stir evenly, so that the epoxy The resin coats the surface of the quartz sand particles; however, after cooling, they are crushed and sieved to obtain hydrophobic particles.

Embodiment 2

[0074] Select 200 grams of 300-mesh quartz sand particles, heat to 400 ° C, add 14 grams of polyamide resin modified epoxy resin, stir well, and add alicyclic amine to form a silicone resin coating on the surface of the quartz sand particles, and then cool , crushing, and sieving to obtain hydrophobic particles.

Abstract

The invention relates to a hydrophobic granule and a preparation method thereof, and a waterproof breathable structure and a forming method thereof. The hydrophobic granule comprises aggregate and a hydrophobic resin film coated on the aggregate, wherein the aggregate size is 6-300 meshes, and the hydrophobic resin film is made of one or a plurality of hydrophobic epoxy resin, bakelite, polyurethane resin and silicone resin, and coated on the aggregate. The preparation method of the hydrophobic granule comprises the following steps: heating the aggregate to 50-400 DEG C; adding the hydrophobic resin, evenly stirring so that a film is coated on the aggregate surface; and cooling, crushing and screening to obtain the hydrophobic granules. The hydrophobic granule can be widely used as a waterproof breathable layer in desert planting, lake bottom seepage-proofing, river course seepage-proofing, landscape water system bottom seepage-proofing, and has favorable waterproof and breathable properties.

Description

technical field [0001] The invention relates to an anti-seepage material, in particular to hydrophobic particles, a preparation method thereof, a waterproof and breathable structure and a formation method thereof. Background technique [0002] In the existing technology, the cost of anti-seepage materials is high, the anti-seepage effect is not good enough, and the timeliness is short, and the anti-seepage is often achieved, resulting in airtight products, causing some side effects when the anti-seepage materials are applied in various fields, such as the landscape lake bottom. Seepage prevention, in order to maintain the water volume of the lake and prevent water from seeping into the ground to supplement the groundwater, the commonly used schemes in the prior art are: scheme 1: use concrete and waterproof materials at the bottom of the lake for waterproofing, but the cost is high, and it is airtight, which destroys the bottom of the lake Biological growth, so its applicati...
