Problems solved by technology

Its waterproof layer is affected by cold and heat cycles and light aging. Over time, there will be water seepage, and cracks will also appear in the leveling layer during the above process, and it cannot be found and repaired in time due to the opaque coverage such as oil stickiness.

Embodiment 1

[0006] Example 1: In a residential building, leave a drain in the bathroom to communicate with the sewer for water and air drainage. After the concrete hollow slabs are installed tightly, cover the depression so that the drain is at the lowest position and cover it with wire mesh , spray the anti-seepage liquid once, and brush it twice with 986 waterproof glue after drying. After the waterproof glue dries at an interval of 0.5 hours, use the anti-seepage liquid to mix cement perlite to make the insulation layer, and cover the insulation layer with old newspapers. Apply anti-seepage cement mortar, normal maintenance for 7 days, smooth the cracks with 968 waterproof glue mixed with cement, and then apply 968 waterproof glue twice, with an interval of 1 hour, after drying, cover it with old newspapers and then wipe it with cement mortar on the covering 20mm thick, cover the cracks after curing and apply waterproof glue twice. Tested for 3 months without leakage and infiltration. ...

Embodiment 2

[0007] Embodiment 2: Polystyrene rigid foam board is used for the insulation layer, and the anti-seepage cement water slurry is directly applied, and the rest are the same as in Example 1. The test is 3 months without seepage, concentration, and infiltration.

Abstract

The present invention discloses making process of building waterproof and heat insulating layer, and belongs to the field of building roof constructing technique. The making process of building waterproof and heat insulating layer includes the following steps: setting draining opening after mounting the hollow concrete slab, brushing one antiseepage fluid layer and two waterproof adhesive layers, spreading heat insulating material, spreading antiseepage cement mortar, curing, flattening to eliminate cracks, brushing two waterproof adhesive layers, covering with waste newspaper, spreading antiseepage cement mortar, curing, and brushing two No. 968 waterproof adhesive layers. The antiseepage fluid consists of sodium methyl silicate, sodium silicate and water in the ratio of 1 to 2 to 7. The present invention has high heat insulating and waterproof performance, long service life and easy maintenance.

Description

technical field [0001] The invention belongs to the waterproof and thermal insulation layer of building roof. Background technique [0002] The traditional building roof construction technology is to spread one sticky oil and two oils on the concrete hollow slab, and then lay the insulation material. Including cement perlite, asphalt perlite precast block, polystyrene rigid foam board, expanded perlite core board, slag, etc. On the insulation layer is a cement mortar leveling layer, and after curing, it will be used as a waterproof layer under the condition that the water content is less than 10%. Commonly used waterproof layers are asphalt oil sticky, waterproof membrane, waterproof glue plus glass cloth, etc. This insulation mainly relies on the porosity of the material. Its waterproof layer is affected by cold and heat cycles and light aging. Over time, there will be water seepage. Cracks will also appear in the leveling layer during the above...
