Abstract

The invention relates to a wet condition impermeable breathable materials which comprises aggregate particles and a hydrophobic resin film and hydrophobic grease, wherein the hydrophobic resin film is arranged on the aggregate particles, the hydrophobic grease is added to the hydrophobic resin film and is in a solid state below the temperature of 50 DEG C, the adding weight ratio of the hydrophobic grease and the hydrophobic resin film is 0.01-0.5:100. The hydrophobic grease is enabled to coat the aggregate particles and powder particles arranged on the surface of the hydrophobic resin film by means of adding of the hydrophobic grease so that the phenomenon of dust flying in the process of construction is prevented. Meanwhile, due to the facts that the hydrophobic grease is added and the hydrophobic grease is in a solid state below the temperature of 50 DEG C, the hydrophobic grease can be changed to be in a liquid state by means of heating when the wet condition impermeable breathable materials are manufactured. Due to the fact that hydrophobic grease is added in the liquid state, the mobility is good. The hydrophobic grease can be changed to be solid after being uniformly stirred and placed when the temperature is lowered to be below 50 DEG C, and therefore the plasticity of the wet condition impermeable breathable materials is enabled to be increased.

Description

technical field [0001] The invention belongs to the field of anti-seepage materials, and in particular relates to a wet state anti-permeation gas material with good fluidity and plasticity and a preparation method thereof. Background technique [0002] The anti-permeation material needs to meet the requirements of air permeability while meeting the requirements of anti-leakage. The anti-permeation materials in the prior art often cannot meet the requirements of anti-leakage and air permeability at the same time. For example, 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, one of the commonly used solutions in the prior art is to use concrete and waterproof materials at the bottom of the lake for waterproofing, and another is to pave the bottom of the lake. Put on a waterproof membrane. However, these methods destroy the growth of lake bottom organisms due to airtightness, th...
