Self-adhesive waterproof roll material for color steel roofs of buildings and method for manufacturing self-adhesive waterproof roll material

Abstract

The invention discloses a self-adhesive waterproof roll material for color steel roofs of buildings. The self-adhesive waterproof roll material is of a multilayer layered structure. A covering layer, a self-adhesive waterproof layer, a non-woven fabric reinforcement layer, another self-adhesive waterproof layer and a partition layer are sequentially combined with one another to form the multilayer layered structure, and the self-adhesive waterproof layers comprise modified asphalt mixtures made of asphalt, base oil, resin, recycled butyl rubber powder and calcite powder. A method for manufacturing the self-adhesive waterproof roll material includes adding the asphalt and the base oil into a reaction kettle according to weights, heating and stirring the asphalt and the base oil to remove water so as to obtain first mixtures, adding the resin into the first mixtures when the temperatures of the first mixtures reach certain temperatures, stirring the resin, uniformly dissolving the resin to obtain second mixtures, adding the recycled butyl rubber powder into the second mixtures when the temperatures of the heated second mixtures reach certain temperatures, stirring the recycled butyl rubber powder to obtain third mixtures, adding the calcite powder into the third mixtures, stirring the calcite powder to obtain fourth mixtures, cooling the fourth mixtures to obtain the modified asphalt mixtures; coating the modified asphalt mixtures on polyester felt and fiber glass gridding cloth composite felt to obtain the finished roll material. The self-adhesive waterproof roll material and the method have the advantages that the self-adhesive waterproof roll material is superior to all other domestic self-adhesive roll materials of the same category and is high in high-temperature-resistant property and practicality; sunlight can be effectively reflected by the covering layer, accordingly, the self-adhesive waterproof roll material is high in heat-insulation and aging-resistant properties and adhesion, and the temperatures of the roofs can be effectively lowered.

Description

technical field [0001] The invention relates to a new building waterproof material and a preparation method of the building roof engineering technology, in particular to a self-adhesive waterproof coiled material specially used for building color steel roofs and a preparation method thereof. Background technique [0002] With the development of the country's economic construction, color steel roofs are more and more used in the construction field due to their light weight, convenient construction, and recyclability, especially in some large-scale construction projects such as railway stations, theaters, and large shopping malls. The share in the project is increasing year by year. [0003] However, with the widespread use of color steel roofs, leakage and corrosion have also occurred during the application process. Some are caused by the deformation of the color steel due to the collision during transportation, some are caused by the deformation of the gaps during the const...
