Preparation method of polymer waterproof coiled material

Abstract

The preparation method comprises the following steps: taking 25-40 parts by mass of PVC resin, 30-45 parts by mass of asphalt, 15-30 parts by mass of polyvinyl chloride and 10-20 parts by mass of rubber, putting into a stirring kettle, heating to 130-180 DEG C, and sufficiently mixing and stirring for 1.5-3 hours at a constant temperature; adding 10-15 parts of carbon black and 10-15 parts of nano calcium carbonate, and mixing and stirring for 15-30 minutes at the constant temperature of 130-150 DEG C; adding 5-10 parts of an anti-aging agent, 5-10 parts of a stabilizer, 5-10 parts of a flame retardant and 5-10 parts of a plasticizer, and mixing and stirring at a constant temperature of 80-120 DEG C for 30-60 minutes; and putting the stirred mixed raw materials into a forming machine for cooling and forming. The manufacturing process of the waterproof coiled material is simple and easy to operate, raw materials are easy to obtain and low in cost, the materials cannot shrink or crack, and the waterproof coiled material is not prone to peeling to cause water leakage when attached to a wall surface. The waterproof coiled material has the advantages of weather resistance, stable performance, and flame retardance.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a preparation method of a polymer waterproof coiled material. Background technique

[0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls and are called waterproof rolls. Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to the different main components, it can be divided into asphalt waterproof membrane, polymer modified asphalt waterproof membrane and synthetic polymer waterproof membrane; according to the different carcass...
