Waterproof air-permeable material, and preparation method thereof application thereof

Abstract

The invention relates to the field of waterproof materials, and particularly provides a waterproof air-permeable material, and a preparation method and application thereof. The waterproof air-permeable material comprises a hydrophobic adhesive and aggregate coated with a hydrophobic material. The aggregate comprises the following raw materials in parts by weight: 30-60 parts of quartz sand, 20-50 parts of haydite and 10-30 parts of slag. The particle size of the quartz sand is 0.05-0.1mm, the particle size of the haydite is 0.07-0.15mm, and the particle size of the slag is 0.2-0.4mm. The waterproof air-permeable material has favorable waterproof effect and excellent air permeability.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a waterproof and breathable material, a preparation method and an application thereof. Background technique [0002] As the name suggests, waterproof and breathable materials are materials that can block water molecules but allow gas to pass through. There are many waterproof materials and breathable materials in the prior art, but there are very few materials that have both functions. The only materials that are waterproof are sufficient. And the air permeability is not good. [0003] Existing potted plants are usually planted in ceramic pots, tile pots or plastic pots. Ceramic pots and plastic pots have a compact body structure and can achieve good water storage, but the air permeability is extremely poor. Moreover, airtightness can easily cause rotten roots, which seriously affects plant growth; earthen pots have good air permeability, but their water storage capacity is n...

[0002] As the name suggests, waterproof and breathable materials are materials that can block water molecules but allow gas to pass through. There are many waterproof materials and breathable materials in the prior art, but there are very few materials that have both functions. The only materials that are waterproof are sufficient. And poor air permeability

[0003] Existing potted plants are usually planted in ceramic pots, tile pots or plastic pots. Ceramic pots and plastic pots have a compact body structure and can achieve good water storage, but the air permeability is extremely poor. Moreover, airtightness can easily cause rotten roots, which seriously affects plant growth; earthen pots have good air permeability, but their water storage capacity is not strong. Water, people usually need to water many times, which is time-consuming and labor-intensive, and wastes water resources

[0004] In the anti-seepage of the landscape lake bottom, in order to maintain the water volume of the lake and prevent water from seeping into the ground, the waterproof effect is usually achieved by adding concrete to the bottom of the lake or laying a waterproof membrane on the bottom of the lake. Although the waterproof effect of the above two methods is good , but airtight, destroying the growth of lake bottom organisms, thus limiting the promotion and application
