产品描述

 


 

product description

 

CBC cross-laminated waterproof membrane is a wet-laid P-type polymer waterproof membrane. It is modified and viscosified with SBR (styrene-butadiene rubber) as the main modifier. The auxiliary modification of the auxiliary agent is made into a coil material, and the cross-laminated film is used as a coil base material or a cladding material to produce a single-sided and double-sided self-adhesive polymer waterproofing membrane.

 


 

Features

 

(1) High tensile strength, two-way tear resistance and excellent watertight performance of the nail rod.

(2) Strong adhesion, can achieve firm and full viscosity, not easy to drown

(3) Cold construction, self-adhesive, no need for open flame, energy saving, environmental protection, economy.

(4) It has self-healing function, the self-adhesive lap joint effect of the body is good, and the underground waterproof can be the same life as the building.

(5) Convenient construction, safety and environmental protection, strong adaptability and wide range of use

Scope of application

 

(1) The product is suitable for waterproofing projects of non-exposed parts such as underground and roofing of various industrial and civil buildings.

(2) It is especially suitable for waterproofing projects such as non-open fire operations and poor base conditions.

 


 

Construction process

 

Wet shop method:

 

Formulating the glue: According to the temperature and humidity, add the appropriate amount of water to the batching bucket according to the water-cement ratio of 0.35~0.40, add 42.5Mpa ordinary Portland cement, stir well with electric agitator until it is even, fine and free of lumps. .

Trial roll: lay the coil on the base surface, align the elastic line or the overlapping edge of the adjacent coil to ensure the overlap width, and release the stress after re-winding.

Scrape the glue: apply the glue to the base layer (planar) or scrape the coated surface (facade) with a thickness of 2~3mm.

Paving the coil: roll the web forward while tearing off the bottom separator.

Extrusion and venting: Push the surface of the coil with a matching tool to extrude the internal gas, so that the coil, the glue and the base layer are completely bonded.

Body lap joint: After the glue layer reaches the strength of the upper body, the lap joint separator is torn off, and the press roller is compacted to realize the lap joint of the coil body.

 

Dry sticking method:

 

Base layer cleaning: The base layer should be solid and dry, free from sediment and garbage, and must not be empty, loose, or sanding.

Coating base treatment agent: spray (rolling) coating should be uniform and not exposed, and the base layer treatment agent enhances the adhesion between the coil and the base layer.

Trial roll: lay the coil on the base surface, align the elastic line or the overlapping edge of the adjacent coil to ensure the overlap width, and release the stress after re-winding.

Cold-adhesive paving: push-rolled coil, tear film, compacted exhaust, ensure the tight bonding of the coil and the base layer, and prevent empty drums.

Take the receiving port: the body is reserved for the self-adhesive lap joint, and the lap joint should be pressed and bonded tightly.
