Abstract

The utility model relates to a slow rebounding sponge composite sealing sheet and comprises a slow rebounding sponge layer and an isolating layer. The former is polyurethane type soft foam plastic through being processed by acrylic acid resin, and the latter is a sheet coated with an isolating agent. The rebounding sponge layer and the isolating layer are glued to become composite. The slow rebounding sponge composite sealing sheet has the advantages of compressibility, slow bounce, good gas tightness, no arrangement position deviation of a sealing piece, low cost and easy and convenient use and is particularly suitable for sealing the plastic component.

Description

Slow-rebound sponge compound seal sheet material

The utility model relates to a kind of sealing material, more specifically says, relates to a kind of slow-rebound sponge compound seal sheet material of plastic production.

The foam material of plastic production is a kind of sealing material of extensive use.In this class material, using more at present is closed cell polyethylene foams and open pore polyurethane class flexible foam plastic, and the former sealing is better, but compressibility is poor; Though latter's tool compressibility, bounce-back is fast, poor air-tightness.In recent years the slow-rebound sponge of Kai Fa plastic production has good compressibility, and bounce-back is slow, and good tightness is arranged.But, produce the raw materials used costliness of this product, also need to build one and overlap independently synthesizer and must have certain production scale, cost of production could reduce, and quality of product is just guaranteed.Still can not accomplish at present both can adjust production scale, can guarantee that again product cost is low, quality good according to market demand.

The purpose of this utility model is: provide a kind of and both can adjust yielding capacity and cost of production is low, both had compressibility, the bounce-back slow according to market demands, good tightness, slow-rebound sponge compound seal sheet material easy to use are arranged again.

The technological scheme that realizes the utility model purpose is: a kind of slow-rebound sponge compound seal sheet material, comprise slow-rebound sponge layer, separation layer, its slow-rebound sponge layer is the polyurethanes flexible foam plastic of handling through acrylic resin, separation layer is the sheet material that single face applies isolating agent, and slow-rebound sponge layer and separation layer bonding are compound.

Above-mentioned compound seal sheet material, the single face of its slow-rebound sponge layer or two-sided with the sticker layer that applies, the one side bonding that scribbles isolating agent with separation layer is compound, also can be with having the basic non-drying glue layer of lining, the one side bonding that scribbles isolating agent with separation layer is compound.

Technique effect of the present utility model is: slow-rebound sponge layer of the present utility model is to adopt commercially available polyurethanes flexible foam plastic, after acrylic resin is handled, original porous structure and performance change, and make it both have compressibility, rebound slowly, and good air-tightness is arranged again, because its sufficient raw, need not to build independently synthesizer again, treatment process is simple, can make at any time according to market demand, not only cost of production is low, and also control easily of quality of product; Separation layer of the present utility model scribbles isolating agent, after peeling off during use, the slow-rebound sponge layer can be sticked on application site, and installation process can not be offset, and is very simple, convenient.

Embodiment below in conjunction with accompanying drawing provides is further described in detail the utility model.

Fig. 1 is first kind of structural representation of the present utility model, the single face of its slow-rebound sponge layer 1 sticker layer 2 that applies, and the one side bonding that scribbles isolating agent with separation layer 3 is compound.

Fig. 2 is second kind of structural representation of the present utility model, its slow-rebound sponge layer 1 two-sided with the sticker layer 2 that applies, and to scribble the one side bonding of isolating agent compound with separation layer 3 respectively.

Fig. 3 is the third structural representation of the present utility model, and the single face of its slow-rebound sponge layer 1 is with having the non-drying glue layer 4 that serves as a contrast base 5, and the one side bonding that scribbles isolating agent with separation layer 3 is compound.

Fig. 4 is the 4th a kind of structural representation of the present utility model, and the two-sided usefulness of its slow-rebound sponge layer 1 has the non-drying glue layer 4 of lining base 5, and to scribble the one side bonding of isolating agent compound with separation layer 3 respectively.

Shown in Fig. 1～4, a kind of slow-rebound sponge compound seal sheet material of the present utility model, comprise slow-rebound sponge layer, separation layer, it is characterized in that, slow-rebound sponge layer 1 is the polyurethanes flexible foam plastic of handling through acrylic resin, separation layer 3 is sheet materials that single face applies isolating agent, and slow-rebound sponge layer 1 and separation layer 3 bondings are compound.The polyurethanes flexible foam plastic of its use can be the polyether-polyurethane flexible foam plastic, or the polyester-polyurethane flexible foam plastic.The isolating agent that separation layer 3 one sides are coated with is generally organosilicon, both has been convenient to peel off, and is convenient to again store.As the sheet material of separation layer 3, can be paper, plastic pellicle or metallic thin film.

The tackiness agent that the single or double of slow-rebound sponge layer 1 of the present utility model applies is a pressure-sensitive adhesive for 2 layers.

The non-drying glue layer 4 that has lining base 5 of the present utility model, its lining base 5 two-sided pressure sensitive adhesives that all scribble, its one side scribbles the one side bonding of isolating agent with slow-rebound sponge layer 1 bonding, another side and separation layer 3.Lining base 5 can be nonwovens, cotton paper or film.The slow-rebound sponge compound seal sheet material of the present utility model that is composited with this non-drying glue layer 4 bondings that have lining base 5, after peeling off separation layer 3, not yielding, not fragile, be more suitable for doing seal stock long and narrow, tiny, baroque installation position.

Separation layer 3 of the present utility model can be bonded in the single face of slow-rebound sponge layer 1 according to user's actual demand, and is perhaps two-sided.

During actual the use, select single face that the compound seal sheet material of the present utility model that separation layer 3 is arranged separation layer 3 or two-sided is arranged at first as required, cut out according to the shape and size at sealing position again, peel off separation layer 3 then, expose the one side that scribbles sticker layer 2 of slow-rebound sponge layer 1, or the pressure sensitive adhesive of non-drying glue layer 4 one side, utilize their cohesiveencess to stick on the sealing position, and then fix with coupled face.

Because slow-rebound sponge layer 1 of the present utility model has compressibility, bounce-back is slow, tightness is good, when making seal stock with it, the processing irregularity degree of coupled face and the adaptive capacity of roughness are improved, seal stock does not depart from the mounting point, and slow-rebound sponge layer 1 used raw material is easy to get the processing convenience, therefore, adaptive faculty to market demand is strong, and cost is low, and is practical.Be particularly useful for the sealing of working of plastics.
