Embodiment 1
[0029] A production process of a waterproof and thermal insulation integrated board includes:
[0030] 1. Combine one side of the polymer waterproof membrane with a layer of non-woven fabric through adhesive, wherein the waterproof membrane includes the base waterproof membrane and the top waterproof membrane;
[0031] 2. Use preheating equipment to preheat the waterproof membrane to make the temperature reach the temperature required for the foaming chemical reaction. The preheating temperature is set at about 30°C;
[0032] 3. Polyurethane insulation material is compounded on the side of the base waterproof membrane compounded with non-woven fabric:
[0033] ①. Mixing of polyurethane insulation materials: send the material barrel to the constant temperature room one day in advance to adjust it to a suitable feeding temperature, and control the ambient temperature at the same time: control the temperature of the mixing room at 20-26 ° C, and control the temperature of the mat...
Embodiment 2
[0036] 1. After one side of the asphalt-based waterproofing membrane is laminated with a layer of HDPE through an adhesive, and then a layer of non-woven fabric is laminated, the waterproofing membrane includes a base waterproofing membrane and a top waterproofing membrane;
[0037] 2. Use preheating equipment to preheat the waterproof membrane to make the temperature reach the temperature required for the foaming chemical reaction. The preheating temperature is set at about 30°C;
[0038] 3. Polyurethane insulation material is compounded on one side of the grass-roots waterproof membrane compounded with HDPE and non-woven fabric:
[0039] ①. Mixing of polyurethane insulation materials: send the material barrel to the constant temperature room one day in advance to adjust it to a suitable feeding temperature, and control the ambient temperature at the same time: control the temperature of the mixing room at 20-26 ° C, and control the temperature of the material at 20 ~26°C, wh...
Embodiment 3
[0042] A production process of a waterproof and thermal insulation integrated board includes:
[0043] 1. Combine one side of the polymer waterproof membrane with a layer of non-woven fabric through adhesive, wherein the waterproof membrane includes the base waterproof membrane and the top waterproof membrane;
[0044] 2. Use preheating equipment to preheat the waterproof membrane, and the preheating temperature is set at about 30°C;
[0045] 3. Compound the formed polyurethane board with an adhesive on the side of the grass-roots waterproof membrane compounded with non-woven fabric;
[0046] 4. On the surface of the polyurethane board, the top layer of waterproof membrane is bonded with an adhesive, and the side of the top layer of waterproof membrane compounded with non-woven fabric is bonded to the polyurethane board.
