Problems solved by technology
[0002] Most of the waterproof membranes in the market now have a single function and can only prevent water leakage
Most of the raw materials used are polymer materials, they have a common feature, water resistance and also prevent the penetration of air, that is, there is no air permeability, and the aging resistance is poor, and the use time is short
Used on the top of the living environment, this kind of membrane has poor air permeability, which seriously affects the comfort of the living environment

Embodiment Construction
[0028] Such as figure 1 As shown, an anti-seepage waterproof and breathable coiled material includes a coiled material body 1 covered with meshes 2, the meshes 2 are bell-shaped, the meshes 2 are filled with sand, and the coiled material body 1 is covered with meshes 2. Both sides of the main body 1 are compounded with polyethylene cloth 3 respectively.
[0029] A method for preparing an impermeable, waterproof and breathable coiled material, comprising the following steps: (1) adding sand to a dryer for drying;
[0030] (2) Mix the sand obtained in step (1) with liquid silicone evenly at 45-55°C, every grain of sand is infiltrated by silicone, mix it for 10-12 minutes, then pour it out and dry it to get wind product sand;
[0031] (3) Melt the polyvinyl chloride plastic to make the coiled material body, put the coiled material body on a pair of rollers, and the paired rollers are provided with needles, and the coiled material passes through the middle of the paired rollers,...

Abstract
The invention relates to an anti-leakage waterproof air-permeable coiled material comprising a coiled material body. The coiled material body is fully provided with meshes, and the meshes are fully filled with sand. Polyethylene cloths are composited on the two faces of the coiled material body. correspondingly. The invention further relates to a preparation method of the anti-leakage waterproof air-permeable coiled material. The anti-leakage waterproof air-permeable coiled material is capable of preventing water from leaking, good in air permeability, resistant to aging and long in service life. According to the waterproof air-permeable anti-leakage coiled material, the using space is expanded, the product content is enriched, and the concept of the waterproof coiled material reaches the new cognitive height. Raw materials are easy to obtain, and the preparation method is simple.
Description
technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an impermeable waterproof and breathable coiled material and a preparation method thereof. Background technique [0002] Most of the waterproof membranes in the market have a single function and can only prevent water leakage. Most of the raw materials used are polymer materials, and they have a common feature, which is water resistance and air penetration, that is, no air permeability, poor aging resistance, and short service life. Used on the top of the living environment, this type of membrane has poor air permeability, which seriously affects the comfort of the living environment. Contents of the invention [0003] In order to solve the above problems, the present invention provides an impermeable waterproof and breathable coil material capable of preventing water leakage, good air permeability, aging resistance, long service life and simple process, and...
