Abstract

The invention provides a non-asphalt-based waterproof coiled material which comprises epoxy resin, allyl alcohol epoxy group-terminated polyether, phenylphosphonic dichloride, 4,4'-diaminodiphenylmethane, a viscosity reducer, a cement affinity agent and linear low density polyethylene. The invention further provides a preparation method of the non-asphalt-based waterproof coiled material. The preparation method comprises the steps of ultrasonic dispersion, wherein the power is 350-400W, and the time is 300-400min; the method further comprises gradient cooling, wherein the temperature is 250-300 DEG C, the rotating speed is 800 rpm, the reduction gradient is 10-12 DEG C/min and the continuous reducing time is 10 min. According to the non-asphalt-based waterproof coiled material disclosed bythe invention, the total combustion time is greatly shortened, and the spread and diffusion of fire disasters are effectively prevented; so that the heat resistance time is effectively prolonged, theapplication range of the product is expanded, and the non-asphalt-based waterproof coiled material has excellent flame retardant effects, water-channeling prevention effects and anti-seepage effects.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and relates to a non-asphalt-based waterproof coiled material, in particular to a non-asphalt-based waterproof coiled material and a preparation method thereof. Background technique [0002] With the rapid development and continuous progress of society, the society's requirements for waterproof materials are also increasing. Waterproof membrane is a commonly used building material in building construction. Non-bitumen-based waterproof membrane is a special product developed for underground and tunnel engineering. A waterproofing membrane that can form a strong anti-bond with post-poured concrete structures. The roll material is a polymer self-adhesive waterproof roll material with a resin polymer sheet as the main waterproof material and a self-adhesive adhesive film on the polymer waterproof base material. Non-bitumen-based waterproofing membrane has become one of the recogn...
