Abstract
The utility model discloses a kind of single-action polyurethane-types to press from both sides charcoal cloth, comprising: the supporting layer that is successively laid with, folder carbon-coating and functional layer are closely bonded using reaction type polyurethane hot-melt adhesive between adjacent every double-layer structure.The reaction type polyurethane hot-melt adhesive that the utility model uses is that chemical reaction solidification occurs by the water in monomer and air, has the function that bonding with this, once solidification is completed, folder charcoal cloth would not occur coming unglued, leak the problems such as charcoal, delamination.Meanwhile charcoal cloth is pressed from both sides with waterproof and breathable performance, it is firmly bonded, windage is small, has very big promotion to the ability of processing gaseous contamination.
Description
Technical field
The utility model relates to a kind of single-action polyurethane-types to press from both sides charcoal cloth, and it is net to be used in filter core and clarifier, air protection etc.
Change industry.
Background technique
It is compound about mainly being carried out using Thermoplastic hot melt glue to folder charcoal cloth in the folder compound market of charcoal cloth, this material
Hot melt adhesive is mainly compound with physical adhesion progress, and this method is easy to cause and comes unglued when pressing from both sides heated charcoal cloth, stress, thus
Cause to press from both sides phenomena such as charcoal is furnished with leakage charcoal, delamination.
Therefore, it is directed to the prior art, a kind of folder charcoal cloth for preventing carbon delamination problems how is designed and developed, is this field
Technical problem urgently to be resolved.
Utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of poly- ammonia of single-action
Ester type presss from both sides charcoal cloth, prevents folder charcoal cloth and falls charcoal, delamination.
The technical scheme in the invention for solving the above technical problem is: a kind of single-action polyurethane-type folder charcoal cloth, packet
Include: the supporting layer that is successively laid with, folder carbon-coating and functional layer are heated using reaction type polyurethane between adjacent every double-layer structure
Glue closely bonds.
The supporting layer uses non-woven fabrics.
The non-woven fabrics quality density is 25-60g/m2。
The folder carbon-coating includes: at least one molecular sieve of active carbon, solid catalyst and specific function, and folder carbon-coating is equal
It is even to be distributed on supporting layer.
The grain diameter of the folder carbon-coating is having a size of 30-60 mesh.
The content of the folder carbon-coating is 80-400g/m2。
The functional layer uses skeleton, which has antibacterial, mould proof and other effects.
The functional layer mass density is 25-60g/m2。
It is not in fall showing for charcoal delamination compared with prior art, the utility model has the beneficial effects that being 1. firmly bonded
As；2. waterproof and breathable performance is good, substantially without windage；3. it is strong to handle gaseous contamination ability；4. odorlessness discharges, polyurethane-hot melt
It is not in smell release after the completion of adhesive curing, polyurethane hot melt is low using temperature, reduces production energy consumption.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, in which:
Fig. 1 is the structural schematic diagram of the utility model preferred embodiment.
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the utility model is described further.In preferred embodiment
Cited such as "upper", "lower", "left", "right", " centre " and " one " term, only being illustrated convenient for narration, rather than to
The enforceable range of the utility model is limited, relativeness is altered or modified, under the content of no substantial changes in technology, when also
It is considered as the enforceable scope of the utility model.
Referring to Figure 1, a kind of single-action polyurethane-type of the utility model preferred embodiment design presss from both sides charcoal cloth, mainly wraps
It includes: supporting layer 1, folder carbon-coating 2 and the functional layer 3 being successively laid with, wherein poly- using response type between adjacent every double-layer structure
Urethane hot melt adhesive closely bonds, and polyurethane hot melt is a kind of moisture-curable polyurethane hot-melt glue, and at 140 DEG C, viscosity is
4000-8000mp*s, securely, permeability is good, is not easy delamination for bonding.
Specifically, supporting layer 1 mainly uses non-woven fabrics, and non-woven fabrics quality density is 25-60g/m2.Carbon-coating 2 is pressed from both sides mainly to wrap
Include: active carbon, solid catalyst and at least one molecular sieve with specific function, press from both sides carbon-coating 2 grain diameter having a size of
30-60 mesh is evenly distributed on supporting layer 1, and the content of folder carbon-coating 2 is 80-400g/m2.Functional layer 3 mainly uses skeleton,
Mass density is 25-60g/m2, the skeleton with specific function is with antibacterial and mouldproof, anti-flammability etc..
Currently, being yet there are no in the market using reaction type polyurethane hot-melt adhesive (abbreviation PUR), this PUR glue is to pass through monomer
Chemical reaction occurs with the water in air and solidifies, bonding is haved the function that with this, once solidification is completed, folder charcoal cloth would not go out
It now comes unglued, leak the problems such as charcoal, delamination；And heating temperature is low when the production of PUR glue；Had using the folder charcoal cloth of PUR glue production anti-
Water permeability, is firmly bonded, and folder charcoal cloth has very big promotion to the ability of processing gaseous contamination substantially without resistance.This is practical
Novel carbon cloth grammes per square metre is big, can reach every square meter 500g substantially, has stronger gaseous contamination ability.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, anyone skilled in the art are not departing within the scope of technical solutions of the utility model, the skill according to the utility model
Art any brief introduction modification, equivalent variations and modification substantially to the above embodiments, still fall within the utility model technical side
In the range of case.
