Abstract

The invention provides a radiation-proof and flame retardant PVC polymer waterproofing membrane and a preparation method thereof, and relates to the technical field of polymer materials. The polymer waterproofing membrane is made from the following raw materials in parts by weight: 30-50 parts of PVC resin, 5-10 parts of polyethylene, 20-30 parts of heavy calcium carbonate, 20-25 parts of wollastonite, 0.5-1.5 parts of polyoxypropylene-polyoxyethylene glycerol ether, 2-3 parts of dihydroxysuccinic acid, 5-10 parts of molten stearic acid, 0.5-0.8 part of 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline, 3-7 parts of barium sulfate, 15-30 parts of industrial white oil, 1-2 parts of nanoscale antimony trioxide, 6-12 parts of melamine cyanurate, 5-10 parts of castor oil and 1-2 parts of a stabilizer. The preparation method of the radiation-proof and flame retardant PVC polymer waterproofing membrane consists of three steps. The radiation-proof and flame retardant PVC polymer waterproofing membrane has the characteristics of aging resistance, low cost and good ultraviolet resistance, and has certain tensile strength and elongation. The radiation-proof and flame retardant PVC polymer waterproofing membrane has large shrinkage rate, and good low temperature flexibility, is convenient for construction, and can be mechanically fixed, or treated with the hot bonding and cold bonding.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a radiation-proof and flame-retardant PVC polymer waterproof coiled material and a preparation method thereof. Background technique [0002] Polymer waterproof membrane is a new type of waterproof membrane introduced and developed by foreign developed countries in the late 1990s. However, most of the waterproof membranes currently on the market use modified asphalt, which tends to become hard and brittle at low temperatures, flows at high temperatures, is not resistant to sunlight, and has a large amount of volatilization. , Not environmentally friendly and highly carcinogenic. [0003] Polyvinyl chloride is a polymer formed by the polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators, or under the action of light and heat according to the mechanism of free radical polymerization. Polyvinyl chloride has poor stability to light and hea...
