Abstract

The invention relates to a seal primer specially used for heat-insulating and waterproof coating, and a preparation method of the seal primer, in particular to a seal primer specially used for heat-insulating and waterproof coating of an aging asphalt roofing, and a preparation method of the seal primer, aiming at solving the problems that as a roof water-proofing material, the existing asphalt felt waterproof coiled material has phenomena of premature aging and cracking, so that a waterproof layer loses efficacy and roofing leakage is further caused. The seal primer is prepared from deionized water, a dispersing agent, a defoaming agent I, filler, pigment, polymer emulsion, a defoaming agent II, a film-forming agent, a mildew preventive and a thickening agent component, wherein the thickening agent component is prepared from a thickening agent and a solvent of the thickening agent. The preparation method comprises the steps of 1, preparing slurry; 2, preparing primer. The seal primer specially used for the heat-insulating and waterproof coating of the aging asphalt roofing is high in strength and elongation, high and low temperature-resistant, aging-resistant, strong in binding power and good in extensibility.

Description

technical field [0001] The invention relates to a special sealing primer for heat-insulating and waterproof coatings and a preparation method thereof. Background technique [0002] Building waterproof engineering is a sub-project to ensure that the structure of buildings (structures) is not invaded by water and the internal space is not harmed by water. Building waterproofing plays an important role in the whole construction project. It involves the basement, wall, floor, wall, roof and many other parts of the building (structure). Its function is to prevent buildings (structures) from seepage and erosion of rainwater, production and domestic water within the design durability period, to ensure that the building structure and internal space are not polluted, and to provide people with a comfortable and safe living space environment. . [0003] House roof waterproofing in building waterproofing engineering is a systematic project, which is related to the normal operation o...
