Abstract

PROBLEM TO BE SOLVED: To make an adhesive having impact absorbing capacity for preventing backing damage caused by a pasty bad workability adhesive as an adhesive for preventing separation, a crack and water leakage of a finishing material in works of tiling and stoning. SOLUTION: A primer (synthetic rubber latex) is stuck on a backing, a waterproof rubber sheet (butyl rubber) is stuck to obtain a waterproof effect and a dispersing/absorbing effect of impact force, and an urethane special elastic adhesive mixed with rubber chips (glass chips) of 3 mm is used as an adhesive with a finishing material to form a uniform adhesive layer having a thickness of 3 mm to perform finishing having no recess/projection. Impact force from the outside is dispersed and absorbed, and since weakness of the adhesive becomes hardness excellent in workability by mixing of the rubber chips, fixing/ coagulating performance increases.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

[0001] The present invention provides a synthetic rubber, latex,
The present invention relates to a method using butyl rubber, urethane, or the like.

[Prior art]

[0002] As a bonding method for attaching a finishing material such as tiles and stones, there is a bonding method using a cement-based adhesive in a mixed mortar construction of a stacking method (cement, sand, water).
In addition, as a relatively new construction method, there is also an adhesion method using an acrylic adhesive or an epoxy adhesive (resin).

[Problems to be solved by the invention]

[0003] However, in these conventional construction methods, problems such as peeling, cracking, and water leakage of the finishing material are particularly frequent in some construction sites, such as steel frame construction sites. The surface cannot keep up with the change. Therefore, by applying a finishing material with a special elastic adhesive, the materials are integrated by the adhesive property peculiar to the elastic adhesive rubber system, and the above-mentioned drawback is solved by following the change of the base.

[Invention for solving the problem]

[0004] Therefore, after applying a special coating agent mainly composed of synthetic rubber latex, a waterproof sheet (butyl rubber) is applied, and a special elastic rubber system (urethane) is used to increase the adhesive force to the base, and the adhesive property of butyl rubber and urethane having elasticity peculiar to urethane. As a result, a waterproof effect can be obtained, and it becomes possible to disperse and absorb forces from external factors, such as internal stress and external stress, which lead to breakage of the finishing material.

Further, a rubber chip (crushed tire waste) or glass chip (crushed glass waste) of 3 mm or more is mixed into a special elastic adhesive (urethane-based) to form a uniform adhesive layer having a thickness of 3 mm. The surface of the finishing material (tile, stone, etc.) becomes uniform and beautiful. In addition, the dripping of the adhesive resulting from the softness found in conventional adhesives, poor workability, etc. can also be achieved by mixing the rubber chip pulverized product into the adhesive, and the adhesive material becomes hard with good workability, The fixation and solidification properties are increased, and the breakage of the substrate caused by the twisting of the finishing material is protected by the hardness of the rubber chip (glass chip).

【Example】

Referring to the drawings, an embodiment will be described with reference to the drawings. In FIG. 1, a primer (synthetic rubber latex) is applied on a base, then a waterproof rubber sheet (with mesh) is applied, and the sheet is adhered by surface bonding. Get. A special elastic adhesive (urethane-based) mixed with rubber chips and glass chips is applied thereon. After applying this bonding method, finish materials such as tiles and stones are constructed.

The embodiment shown in FIG. 2 is an example in which the problem is solved by the construction method of FIG. 1. First, a waterproof rubber sheet is applied after applying a primer, and strong adhesion between the base surface and the adhesive layer is performed by surface bonding. Furthermore, a special elastic adhesive mixed with rubber chips and glass chips can be used to easily create an adhesive layer with a uniform thickness and a cushioning property. Therefore, the waterproofing effect is maintained without damaging the waterproofing sheet.
Then, since all the materials are integrated by the adhesive force peculiar to the elastic adhesive rubber system and follow the change with respect to the structural crack due to the expansion and contraction of the base, no material change is observed after the base material.

【The invention's effect】

[0008] The present invention is embodied in the form described above, and has the following effects. Apply a primer on the underlayer, and apply a waterproof rubber sheet (butyl rubber) on it to obtain a waterproof effect. In addition, rubber chips and glass chips are mixed into the adhesive to give the adhesive layer hardness and cushioning. This makes it difficult for the surface of the finishing material to reach the ground. In addition, by mixing rubber chips and glass chips, the waterproof rubber sheet can be protected, and at the same time, it can be used as an adhesive with a hardness that is easy to apply. Can be finished. The thickness of the adhesive layer can prevent the damage by absorbing and dispersing the impact on the waterproof sheet and the base against the expansion and contraction of the finishing material by mixing the rubber chip and the glass chip.
