The invention provides a waterproof gas-permeable membrane. The waterproof gas-permeable membrane sequentially comprises a waterproof surface layer, a gas-permeable layer and a base material layer from top to bottom, wherein the base material layer is adhered with the waterproof surface layer through the gas-permeable layer; the gas-permeable layer contains the following components in parts by mass: 55-75 parts of polyether ester, 11-15 parts of an activated substrate and 3-6 parts of an aid; the activated substrate contains the following components in parts by mass: 8-15 parts of calcium carbonate and 10-17 parts of linear low-density polyethylene; the aid contains the following components in parts by mass: 3-6 parts of a coupling agent, 3-5 parts of a lubricating agent, 1-3 parts of an antioxidant and 1-3 parts of a dispersing agent. The waterproof gas-permeable membrane has excellent bonding strength with an outer wall of a building, has excellent adhesive strength and good waterproof and gas-permeable effects and is durable, moderate in cost and suitable for being generalized and used.

The invention provides a preparation method for a sandstone paster stone. The preparation method comprises the following steps: (1) laying gridding cloth or non-woven fabric; (2) at least coating onceby sandstone texture paint and drying after coating, forming a sandstone texture paint layer after drying, wherein a thickness thereof is 1-12 mm; (3) coating the surface of the dried sandstone texture paint by facing paint, and performing texture effect treatment, drying. The method is capable of performing multiple times of a multi-layer coating technology on a base material, and realizing therealistic sandstone simulated effect in combination with a texture effect treatment technology, and simple and efficient in technology; using the sandstone texture paint as a basis for presenting thesandstone effect, better in waterproof breathable effect, preventing the paster stone from being frost-cracked because water vapor is coagulated in the paster stone under a cold climate condition, andimproving weather resistance and service life of the paster stone; and light in weight, safe and beautiful while used as a high-rise outer wall decorative sheet, and suitable for popularization and application.

The invention relates to a preparation method of a waterproof breathable membrane, comprising the following steps: dissolving dopamine in methanol to obtain a dopamine solution; dissolving polyamines in water to obtain a polyamine solution; dissolving acid chlorides in an organic solvent to obtain an acid chloride solution ; soak the basement membrane in the dopamine solution and dry to obtain the first basement membrane; soak the first basement membrane in the polyamine solution and dry to obtain the second basement membrane; drench the acid chloride solution Wash the second base film and dry to obtain a waterproof and breathable film; the acid chloride has the structure shown in formula (I): wherein, 2≤n≤5. The waterproof and breathable membrane prepared by the above method has more excellent waterproof and breathable functions.

The invention provides a waterproof and ventilating structure of a solar junction box. A cover plate is installed on a hole in the front end of a body of the solar junction box, the cover plate is connected with the body in a sealed mode through a seal ring, exhaust holes are formed in the cover plate, a waterproof ventilating membrane is correspondingly arranged in the exhaust holes, the air in the solar junction box can be exhausted through the waterproof ventilating membrane, and water vapor outside the solar junction box cannot enter the solar junction box. In addition, due to the facts that sealing clamping grooves are further formed in the positions of connection between the solar junction box and cables of a cable connector, and sealing is carried out through corresponding cable seal rings, and the possibility that the water vapor enters the solar junction box through the positions of the connection between the solar junction box and the cables is eliminated. The waterproof and ventilating structure of the solar junction box is applicable to the solar junction box which is installed outdoors, and has the advantages that the effect of water resistance and the effect of ventilation are good, the service life is long, and the problem that devices inside the solar junction box can be easily influenced by the environment to cause reduction of performance is solved.
