Abstract

The invention discloses the puncture resistance water-proof sheet and preparing method, comprising 75-85 parts low density polyethylene, 5-10 parts thermoplastic elastomer SBS, 2-8 parts color masterbatch, 2-5 parts auxiliary agent and 5-10 parts filling agent. The invention uses extrusion forming method. The sheet has advantages of good water-proof property, antiseep, weatherability, high hot strength, low linear expansion, big frictional factor, large temperature range, long life and low cost. The invention can be used in underground, road, harbour, and culverts.

Description

technical field [0001] The invention belongs to the field of waterproof material preparation, and relates to an enhanced puncture-resistant waterproof sheet (LECB for short) and a preparation method thereof. Background technique [0002] The main raw materials used to make waterproof sheets are modified rubber and single synthetic resins, such as polyvinyl chloride, polyethylene and other polyolefin resins. The waterproof rolls made of the above materials have small elasticity, low elongation, and Low tensile strength, poor durability and low temperature resistance lead to extremely poor waterproof and leakage properties of the coil. Building leakage is a common problem that plagues the construction industry. In recent years, relevant departments such as the Ministry of Construction and the construction committees of various provinces and cities have issued various regulations and regulations. Various scientific research units have also developed many new waterproof materia...
