Problems solved by technology

[0002] At present, in housing construction, high-molecular polyethylene polypropylene (polyester) and polyvinyl chloride (PVC) waterproof membranes are rarely used, because when these materials are directly used for roof construction, the water will foam and cannot be constructed, and this material It is also easily affected by ultraviolet radiation, so the country prohibits and does not design these coiled materials for roofing, but only uses this kind of material in the basement, and uses cement and glue powder to paste construction, and the effect is not good due to different construction methods during construction same, easy to fall off
At present, SBS modified bitumen waterproof membrane is mainly used for roof waterproofing, but this material has disadvantages such as not being environmentally friendly, high cost, poor adhesion, inaccessibility of people on the roof, and short service life. In a relatively humid environment, SBS The material is also easy to peel off and produce hollowing
Therefore, it is imperative to research and develop a waterproof adhesive that solves the poor bonding performance of existing waterproof materials in humid environments.

Embodiment 1

[0024] Waterproof binder, including fabric, is made by mixing the following raw materials in weight percentage:

[0025] White cement 35%, mica powder 10%, gray calcium powder 10%, silica fume powder 10%, quartz sand 34%, dispersible rubber powder 0.3%, organic silicon powder 0.5%, lignin 0.1%, polypropylene fiber 0.1 %; The quartz sand is 20-80 mesh.

[0026] The construction method of waterproof adhesive is as follows:

[0027] Mix the fabric and water according to the volume ratio of 3:1 to form a paste, and then directly apply to the two surfaces of the polyethylene polypropylene waterproofing membrane for bonding, or directly apply to the roofing substrate and the waterproofing membrane. After the exposed surface, the waterproof membrane is bonded. The total coating thickness of the fabric is 5mm, the thickness of the surface bonded to the roof base is 2mm, and the thickness of the exposed surface is 3mm.

Embodiment 2

[0029] Waterproof binder, including fabric, is made by mixing the following raw materials in weight percentage:

[0030] White cement 40%, mica powder 8%, ash calcium powder 7%, silica fume powder 10%, quartz sand 33.9%, dispersible rubber powder 0.5%, organic silicon powder 0.3%, lignin 0.2%, polypropylene fiber 0.1 %; The quartz sand is 20-80 mesh.

[0031] The construction method of waterproof adhesive is as follows:

[0032] Mix the fabric and water according to the volume ratio of 4:1 to form a paste, and then directly apply to the two sides of the polyethylene polypropylene waterproof membrane for bonding, or directly apply to the roof base and the waterproof membrane. After the exposed surface, the waterproof membrane is bonded. The total coating thickness of the fabric is 6mm; the thickness of the surface bonded to the roof base is 2mm, and the thickness of the exposed surface is 4mm.

Embodiment 3

[0034] Waterproof binder, including fabric, is made by mixing the following raw materials in weight percentage:

[0035] White cement 30%, mica powder 15%, lime calcium powder 10%, silica fume powder 7%, quartz sand 37%, dispersible rubber powder 0.6%, organic silicon powder 0.1%, lignin 0.2%, polypropylene fiber 0.1 %; The quartz sand is 20-80 mesh.

[0036] It also includes a primer, which is a mixture of the following raw materials by weight percentage:

[0037] White cement 40%, gray calcium powder 10%, silica fume powder 13%, sepiolite powder 10%, heavy calcium 26.2%, polyvinyl alcohol powder 0.6%, lignin 0.2%.

[0038] The construction method of waterproof adhesive is as follows:

[0039] Mix the fabric and water into a paste according to the ratio of 4:1 and apply it on the exposed surface of the waterproof membrane with a thickness of 3mm; mix the primer and water into a paste according to the ratio of 2:1 and apply on the substrate , And then bond with the other side of the p...

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a waterproof bonding agent and a using method thereof. The waterproof bonding agent comprises a facing material which is prepared by mixing the following raw materials: white cement, mica powder, gray calcium powder, silicon ash, quartz sand, dispersible rubber powder, organic silicon powder, ligninand polypropylene fiber. The waterproof bonding agent has high waterproofness, can be applied to humid environments, fills up the blank in the technical field, and has high thermal insulation, ultraviolet resistance and abrasion resistance; and the service life of a waterproof coiled material after bonding according to a standard specification is not less than 5 years, and the service life of a roof waterproof coiled material using the waterproof bonding agent is not less than 10 years.

Description

(1) Technical field [0001] The invention belongs to the technical field of house construction, and particularly relates to a waterproof adhesive and a use method thereof. (2) Background technology [0002] At present, high molecular polyethylene polypropylene (polyester) fiber and polyvinyl chloride (PVC) waterproofing membranes are rarely used in housing construction, because when these materials are directly used for roof construction, they cannot be constructed due to high moisture and foam. It is also susceptible to ultraviolet radiation. Therefore, the country prohibits and does not design these coils for roofing, but uses such materials in the basement, and uses cement and glue powder to paste the construction, and the effect of different construction methods during construction is not exhaustive. Same and easy to fall off. At present, the roof waterproofing mainly uses SBS modified bitumen waterproofing membrane, but this kind of material has disadvantages such as unenvir...
