Problems solved by technology

The mask of self-adhesive membrane mainly adopts HDPE film (that is, strong cross membrane), while the base of SBS waterproof membrane mainly adopts polyester tire. The above two materials have their own defects, such as large shrinkage rate of cross membrane and heat aging Poor performance, complex process and high price, while polyester tire can only be used as tire base, without waterproof function and high price

Abstract

The invention provides a strong film and a preparation method and an application thereof, which belong to the technical field of coiled materials. The strong film of the invention includes, by mass, the following components: 20-80% of high molecular materials; 1-20% of POE; 0.5-75% of composite functional materials; and 0.5-6% of color masterbatch; the high molecular materials are PP and / or HDPE;and the composite functional materials are one or more of functional masterbatch which is synergistically modified by mica and glass fiber, carbon fiber materials and polyester fiber materials. The strong film adopts the composite functional materials and cooperates with other components to make the film have the advantages of high strength, excellent high temperature resistance, small shrinkage,moderate elongation rate, good heat aging performance, and the like.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a strong membrane and its preparation method and application. Background technique [0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the tire base are provided to downstream customers in the form of rolls, called waterproof rolls. Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage. [0003] At present, the waterproof material of the waterproof membrane mainly adopts polymers. The mask of self-adhesive membrane mainly adopts HDPE film (that is, strong cross membrane), while the base of SBS waterproof membrane mainly adopts polyester tire. The above two materials have their own defects, such as large shrinkage rate of cross membrane and heat aging The performance is poor, the process is complicated, and the p...
