CN2266648Y - Coldproof sealing strip for door and window - Google Patents

Abstract

The utility model relates to a coldproof sealing strip for door and window, which is composed of a raised elastic cloth layer (1) weaved by polypropylene filament, a polypropylene plastic stick which is heat seal together with a raised elastic flannelette layer (1), a hot melt voltage-sensitive adhesive layer (3) sticking and covering the other side of the polypropylene plastic stick (2) and an antisticking silicon oil paper (4) attached on the lower side of the voltage-sensitive adhesive layer (3). The utility model is characterized in that the efforts for coldproof sealing and dust prevention are good; the tensile strength is high; the breaking is different under the condition of adhesive seal, the aging can be resisted; the utility model can be continuously used at least ten years; residue does not exist when taking off; compared with a foam sealing strip, the construction cost is almost same.

Description

The door and window Winter-proof air-tight strip

The utility model relates to a kind of door and window Winter-proof air-tight strip, be applicable to the door and window that various materials such as iron, wooden are made.

At present, the door and window sealing strip of selling on the market is to be coated with adhesive sticker to make on the sponge foam strip.Its thickness is about 8mm, and the actual (real) thickness after the compression is about 0.3-0.4mm, and the door and window minimum aperture of ordinary residence is more than 1.5mm, maximum reached 3mm.As seen, sponge foam seal bar does not reach desirable winter protection sealing effectiveness.In addition, sponge foam seal bar is not ageing-resistant, needs only a winter with regard to natural aging, and powder falls gradually.Because its tensile strength is low and the soft body structure of itself, in bonding process, easily breaks, and influence its globality.When not required, can not take off by whole piece, for the user has increased trouble again in cleaning.

In order to overcome many deficiencies that existing sponge foam seal bar exists, the purpose of this utility model is, improve the structure of existing weather strip, design a kind of hard and soft unification that has, tensile strength is big, and is ageing-resistant, bonding firm, long service life, a kind of door and window Winter-proof air-tight strip of noresidue when taking off.

For achieving the above object, the design scheme of door and window Winter-proof air-tight strip of the present utility model is, for the tensile strength that strengthens weather strip and bonding globality, adopting the polypropylene plastics bar in the structure is the skeleton of weather strip, and on this plastic strip, be provided with the piloerection stretch velvet layer of cloth that becomes by the polypropylene fibre silk weaving, with the sealing insulation that increases weather strip, and ageing-resistant performance, covering bonding firm pressure-sensitive adhesive layer at the another side of polypropylene plastics bar.

For the structure to the utility model door and window Winter-proof air-tight strip has further understanding, details are as follows in conjunction with embodiment of the present utility model:

Embodiment, the door and window Winter-proof air-tight strip.

Accompanying drawing is the structural representation of the utility model door and window Winter-proof air-tight strip.

With reference to accompanying drawing, the structure of door and window Winter-proof air-tight strip of the present utility model includes with polypropylene fibre BCP swollen The piloerection stretch velvet layer of cloth (1) that the body long filament is made into is with gathering that piloerection stretch velvet layer of cloth (1) is heat sealing at Propylene plastic strip (2), the hot-fusible pressure-sensitive adhesive layer (3) that is covering at polypropylene plastics material strip (2) another side, And the antiseize silicone oil paper (4) that adheres to below pressure-sensitive adhesive layer (3) forms. This door and window Winter-proof air-tight strip exists Thickness under the bulk state is 3.5mm, and the thickness after the compacting reaches about 1.2mm. The sealing bar can be made The series of products of different in width, thickness, the door and window needs of making to satisfy various materials.

During use, can select according to the size in door and window slit the door and window Winter-proof air-tight strip of different size. Tool Gymnastics is done, and is earlier that the dust eraser examination at sash counterpart place is clean, presses then required length with close Strip of paper used for sealing is cut off, and takes off silicone oil paper, and in the face of in the window tooth, the compacting of exerting oneself a little from top to bottom gets final product with glue. If the gap is bigger, also can be symmetrical add glued one, makes it reach desirable winter protection sealing effectiveness.

The characteristics of door and window Winter-proof air-tight strip of the present utility model are that sealed cold-proof prevents dust heat insulation effect Good; Tensile strength is big, is difficult for during stickup breaking; Ageing-resistant, can use continuously 10 under field conditions (factors) More than year; Firm pasting does not generally change its firmness at ± 40 ℃; Nontoxic, tasteless; Whole piece Noresidue when taking off, sticking take from as; Its cost and sponge foam seal bar ratio, very nearly the same.

Claims (1)

1, a kind of door and window Winter-proof air-tight strip, it includes silicone oil paper (4), pressure-sensitive adhesive layer (3), it is characterized in that it also includes the polypropylene plastics bar (2) that covers on pressure-sensitive adhesive layer (3), and in the top of polypropylene plastics bar (2), form with polypropylene plastics bar (2) heat seal piloerection stretch velvet layer of cloth (1) together.
