Abstract

The invention provides a PVC anti-aging waterproof roll. The PVC anti-aging waterproof roll comprises modified polyvinyl chloride, thermoplastic butadiene styrene rubber, stabilizer, epoxy resin, paraffin, sterol, antiager, pyrophylite powder, isophoronediisocyanate and polyhexamethylene phosphate. The invention further comprises a preparation method of the PVC anti-aging waterproof roll. The preparation method comprises an ultrasonic dispersion step, the power is 1350-1400 W, and the ultrasonic time is 3-5 min. According to the PVC anti-aging waterproof roll, the deformation resistance is high, the size change rate is 0.1-0.5%, the elongation at break is 510-550%, and tension reaches 1050-1025 N; and thermal ageing tension retention rate is 94.8-99.7%, the elongation retention rate is 90-95%, the bending property at low temperature is as low as -28 DEG C, crack is avoided, scratch and wear resistance is achieved, and the property is durable and stable.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material and relates to a PVC aging-resistant waterproof coiled material, in particular to a PVC aging-resistant waterproof coiled material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is one of the earliest industrialized plastic varieties in the world. It is a general-purpose resin with excellent performance and low price. It has excellent flame retardancy, corrosion resistance, wear resistance, small friction coefficient, low thermal conductivity, and sealing performance. Good, dustproof, sound insulation, earthquake resistance, weather resistance and other advantages, it has been widely used in the fields of construction, light industry, agriculture, packaging, daily use, etc. Due to the disadvantages of high melt viscosity and poor impact resistance, PVC is limited as a structural material. application of materials. [0003] With the rapid deve...
