Problems solved by technology

The leakage on the top floor is mainly concentrated in the "top slab or side wall of the top floor resident's house", which is mainly in the dripping mode; the waterproof material used in the roof at present makes the waterproof life far short of the service requirements, and cannot be 100% bonded to the roof. The reason for thermal expansion and contraction is that the water infiltrated by the formed leak point flows under the waterproof layer, causing water leakage, and it is difficult to find where the real leak point is, and it cannot be repaired or replaced as a whole

Embodiment 1

[0026] Example 1 (the area of ​​a grain reserve in a certain city is 4000㎡):

[0027] Step 1), remove the SBS membrane on the roof and parapet, clean up excess debris and grease on the base surface, and ensure that the base surface is clean and firm. Level the construction base surface and fix the active joints. The surface temperature of the construction surface should be higher than 5°C and lower than 35°C, and then apply the first bottom waterproof layer paint on the construction base surface. The first bottom waterproof layer paint should be 1.2 parts Water, 1.1 parts of waterproof layer liquid material, and 3.5 parts of waterproof layer powder material are mixed together, spread evenly with a scrub brush or roller, and then dry for 2 hours. There are no wall-penetrating pipes and inner corners of the wall to be treated on this construction base.

[0028] Step 2), when the surface temperature of the construction surface should be lower than 35°C, apply the third bottom wa...

Embodiment 2

[0037] Coat the heat-insulating and waterproof composite coating on bamboo baskets with a diameter of 20cm and a height of 10cm made of bamboo rafts, fully stir with a ratio of 0.8 parts of waterproof layer liquid material and 0.7 parts of waterproof layer powder material, and then apply it on the bamboo basket with a brush Brushing requires no air bubbles, no pinholes, no flow drop, and then curing for 9 hours. Then fully stir with the ratio of 0.9 part of waterproof layer liquid material and 0.1 part of water, and then apply it on the bamboo basket with a brush. It is required to paint evenly and maintain for 72 hours. The thermal insulation layer coating is applied with a brush, and the coating is required to have uniform color, continuous surface, no leakage, no flow, no air bubbles, no pinholes, and 72 hours of curing.

[0038] Then add water to the bamboo basket, continuously soak the water, and raise fish in the water. The total time is more than 12960 hours, and the ba...

Abstract

The invention belongs to the field of building paint and particularly relates to paint for a heat-insulation and water-proof composite coating and a construction process of the paint. The paint comprises water-proof-layer paint and heat-insulation-layer paint, wherein the water-proof-layer paint is prepared from a water-proof-layer liquid material, a water-proof-layer powder material and non-wovenfabric. The construction process comprises early-stage preparation and construction. The construction process is applied under the condition that a main body structure of a building is not damaged, the water-proof period of the heat-insulation and water-proof composite coating is as long as the service life of the building, internal temperature of the building keeps constant under the condition of high temperature of sunlight, and a heat insulation layer not only can reduce internal temperature of a house, but also can reduce the whole urban heat island effect. The heat-insulation and water-proof composite coating has the unique advantages of resistance to acid, base, corrosion and aging, heat insulation, prolonged service life of the building and the like, the renovation and maintenanceprobabilities are low, water and electricity consumption is reduced, and the coating is more economical, more energy-saving and more environmentally friendly.

Description

technical field [0001] The invention belongs to the field of architectural coatings, in particular to a coating for heat-insulating and waterproof composite coatings and a construction process thereof. Background technique [0002] According to the statistics of the China Building Waterproof Association in 2014, the water leakage rate of domestic buildings is as high as 95.33%, which means that almost every building has different degrees of water leakage. The building leakage rate from high to low is the top floor (95%), residential buildings (63.6%), and underground space (57.4%). The leakage on the top floor is mainly concentrated in the "top slab or side wall of the top floor resident's house", which is mainly in the dripping mode; the waterproof material used in the roof at present makes the waterproof life far short of the service requirements, and cannot be 100% bonded to the roof. Due to thermal expansion and contraction, the water infiltrated by the formed leak poin...
