Abstract

The utility model relates to a novel water-tight sealing strip for building, and belongs to the technical field of accessories for door, window and curtain wall of building. The novel water-tight sealing strip is characterized in that a compact rubber layer (1) and an expanded rubber layer (2) are included, wherein the expanded rubber layer (2) is embedded on the working surface of the compact rubber layer (1), and the expanded rubber layer (2) and the compact rubber layer (1) are formed by being vulcanized by one step in a co-extrusion manner. The novel water tight sealing strip for building has the advantages of excellent sealing and water-tight effects, long service life and convenient installation and use.

Description

Novel water stopping type building weather strip

(1) technical field

The utility model relates to a kind of building weather strip, particularly relates to a kind of novel water stopping type building weather strip.Be used for big facade, the outer better higher door and window sealing strip of waterproof requirement of glass, particularly particularly suitable at the high-grade door and window curtain wall in humidity rainy (mist) area, substitute conventional door and window curtain wall weather strip.Belong to building doors and windows curtain wall auxiliary equipment technical field.

(2) background technology

Conventional building doors and windows curtain wall weather strip has determined its quality of sealing performance in use in the process of section bar assembling.It utilizes the elasticity of rubber itself to realize that sealing do not leak, and the excessive assembling severe patient that then is difficult for can cause glass breakage but the problem that occurs easily is the weather strip Cross section Design, though the too small easily assembling of weather strip Cross section Design poor sealing performance.Particularly in humidity rainy (mist) area, because air humidity is too big, the sealing performance of door and window is required higher, hazing in the common hollow glass be sealing not in place due to, especially when using a period of time weather strip situation that wears out after the elastic failure even more serious.Present conventional solution can only place hope on section bar, sealing strip material can the batch sizes tolerance stable and workman's assembly quality.But this problem there has been a new solution route now again

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of sealing, stagnant water effect good, long service life, novel water stopping type building weather strip easy to install.

The purpose of this utility model is achieved in that a kind of novel water stopping type building weather strip, it is characterized in that it comprises closely knit rubber layer and expanded rubber layer, described expanded rubber layer is entrenched in closely knit rubber layer working surface, and described expanded rubber layer and closely knit rubber layer adopt sulfidization molding of co-extrusion mode.

The novel water stopping type building of the utility model weather strip, closely knit rubber layer provides installation position and main sealing function, and the expanded rubber layer plays two road sealing effects.When door and window in use, meet (rain) water after expanded rubber can expand automatically, thereby the deficiency of auxiliary original closely knit rubber seal performance, and after air humidity reduced, moisture can be separated out from expanded rubber automatically.

The expanded rubber layer only plays auxiliary sealing effect, thereby need only cover closely knit rubber surface expansion effect slightly thinly, can be not excessive even cause the situation of glass breakage to take place because of the weather strip back stress that expands.

Compare with existing door and window sealing strip, the utlity model has following characteristics:

1, the assembly technology identical with the routine building weather strip;

2, add expanded rubber, have two road sealing effects;

3, do not change existing door-window section bar design and assembling;

4, solved the sealing of the door and window curtain wall in moist rainy (mist) area;

5, long service life.

(4) description of drawings

Fig. 1 is the novel water stopping type building of a utility model weather strip section structure schematic diagram.

Among the figure:

Closely knit rubber layer 1, expanded rubber layer 2.

(5) specific embodiment

Referring to Fig. 1, the novel water stopping type building weather strip that the utility model relates to, be made up of closely knit rubber layer 1 and expanded rubber layer 2, described expanded rubber layer 2 is entrenched in closely knit rubber layer 1 working surface, and described expanded rubber layer 2 adopts sulfidization molding of co-extrusion mode with closely knit rubber layer 1.

So-called expanded rubber is meant and adds the water-swellable resin in the rubber, and the compatibility of this resin and water is good, and very firm with combining of rubber, can meet water and expand repeatedly and do not separate out.

Claims

1. a novel water stopping type is built weather strip, it is characterized in that it comprises closely knit rubber layer (1) and expanded rubber layer (2), described expanded rubber layer (2) is entrenched in closely knit rubber layer (1) working surface, and described expanded rubber layer (2) adopts sulfidization molding of co-extrusion mode with closely knit rubber layer (1).
