Abstract

The invention provides a modified asphalt waterproof coiled material with a heat insulation function and a preparation method thereof. The coiled material comprises a bottom film 1, a first modified asphalt layer 2-1, a base layer 3 and a second modified asphalt layer 2-2, and is characterized by also comprising a coverage layer 4, wherein the first modified asphalt layer 2-1 and the second modified asphalt layer 2-2 are sequentially arranged on the upper surface of the bottom film 1; the base layer 3 is arranged between the first modified asphalt layer 2-1 and the second modified asphalt layer 2-2; and the coverage layer 4 is arranged on the upper surface of the second modified asphalt layer 2-2. The surface coverage layer is prepared by proportioning raw materials for a film forming agent, synthesizing the film forming agent and preparing a coverage layer material. The performance of the modified asphalt waterproof coiled material is increased by changing the category and the proportion of a filling material in the raw materials in a waterproof structural layer, so that the modified asphalt waterproof coiled material has extremely high waterproof performance and the heat insulation function and is an ideal building energy-saving product.

Description

technical field

[0001] The invention relates to a building waterproof material, in particular to a modified asphalt waterproof coiled material with thermal insulation function which is suitable for roof or basement Background technique

[0002] At present, the waterproof membrane products widely used in roofing and basement in my country's existing market are mainly composed of three series, namely: 1. Modified asphalt waterproof material, 2. Polymer plastic waterproof sheet, 3. Synthetic rubber waterproof Coil. From the analysis of practical application and material composition, products of any specification in these three types of waterproof membranes do not have the function of heat preservation and heat insulation, but only have a single waterproof performance. However, with the rapid development of all walks of life, the consumption and demand of energy are increasing, resulting in the dwindling of resources such as coal, oil, and natural gas, which has attracted great ...
