Abstract
The invention belongs to the field of adhesives, and especially discloses an electric heating epoxy resin adhesive film. The adhesive film comprises two layers of oilpapers arranged oppositely, and is characterized in that cutting lines are arranged on the outer sides of the oilpapers; epoxy adhesive layers are coated on the inner sides of the oilpapers within the area defined by the cutting lines; a stainless steel resistance wire layer is correspondingly arranged between the epoxy adhesive layers of the two oilpapers; a low-resistance metal copper mesh connected with the resistance wire layer is arranged transversally corresponding to the cutting lines. According to the invention, the adhesive film is prepared with medium-high-temperature latent epoxy resin adhesive and interlayer resistance wires. The film has all advantages of epoxy resin adhesives, and has the advantages of convenient application, high curing speed, higher safety compared to low-temperature curing adhesives, high application temperature, and convenient detachment of bonded structures.
Description
(1) technical field
The invention belongs to the sizing agent field, particularly a kind of electrically heated epoxy resin film.
(2) background technology
Along with improving constantly of quality of life, broad masses of the people improve constantly the specification of quality of extensive stock and service, the tissue of these commodity and service is provided or go together between competitive pressure continue to increase, how to attract more human consumers' eye, become the large production enterprise that arrives, a little important factor to the competition of all kinds of retail shops.The decorative plate of all kinds of magnificent mansions arises at the historic moment, and we often see that some word of billboard adds and comes off from billboard, and normally billboard is some or all of to come off because fixing bad or of long duration stationary installation ageing failure causes for this; If the part come off can not be repaired rapidly, probably cause the permanent damage of billboard, and need a large amount of fund of cost to reset billboard.
Coming off of home-use construction tile, also have a strong impact on the attractive in appearance of house in addition.And the stickup of construction tile is normally by cement.In order to repair the concordant of rear ceramic tile and ceramic tile on every side, with the cement reparation, usually original cement need to be cleaned out, this labour intensity is large, has more bothered if the ceramic tile that comes off is just cleared up aloft.
Thinking needs the structure bondd firmly and fast very many in daily life with in producing like this.Epoxy adhesive is high with its cohesive strength, environment-protecting asepsis, the little advantage of consumption and be widely used, but common epoxy resin adhesive or need to be to the whole heating of bonding parts, fast with reaction under room temperature, and mechanical property and shelf time are short and second-order transition temperature is on the low side; And in case solidify, adhesive structure is wanted again to take apart very difficult.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of bonding firmly, remove electrically heated epoxy resin film easily.
The present invention is achieved through the following technical solutions:
A kind of electrically heated epoxy resin film, comprise the two-layer oilpaper be oppositely arranged, it is characterized in that: be provided with cutting line on described oilpaper outer side, on the oilpaper medial surface, be coated with epoxy adhesive layer in the regional extent of cutting line, in the middle of the epoxy adhesive layer of two oilpaper, correspondence is provided with electric resistance of stainless silk layer, on horizontal corresponding cutting line position, is provided with the small resistor metal copper mesh of contact resistance silk layer; Wherein, epoxy adhesive layer is mixed by rubber modified epoxy resin, standard solid type epoxy resin, aerosil, grade chopped strand, dicyandiamide solidifying agent and 2-benzothiazolyl mercaptan promotor.
More excellent scheme of the present invention is:
The aerosil high-speed stirring that the rubber modified epoxy resin that described epoxy adhesive layer is 175-205 by the epoxy equivalent (weight) of 65 weight parts is heated to add after 70 ℃ 3 weight parts is uniformly dispersed it, the grade chopped strand that adds 5 weight parts stirs, adding epoxy equivalent (weight) is standard solid type epoxy resin 35 weight parts of 2500-3100 again, in 130 ℃ of lower stirring and dissolving, be cooled to 90 ± 2 ℃, add the dicyandiamide solidifying agent high-speed stirring of 6 weight parts, the 2-benzothiazolyl mercaptan promotor of adding 3 weight parts when temperature is down to 70 ± 2 ℃ makes; Above-mentioned is hot setting epoxy adhesive formula in latent.
Described small resistor metal copper mesh connects power supply,, to metal copper mesh and the power supply of resistance wire layer epoxy adhesive layer is heated by power supply.
The present invention by high temperature latent epoxy resin adhesive interlayer resistance wire make, not only have all advantages of epoxy resin adhesive, and have easy to use, curing speed is fast, relative low temperature curing adhesive safety, use temperature is high, and adhesive structure is removed advantage easily.
(4) accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is that master of the present invention looks cross-sectional view;
Fig. 2 is plan structure schematic diagram of the present invention.
In figure, 1 oilpaper, 2 epoxy adhesive layers, 3 resistance wire layers, 4 cutting lines, 5 small resistor metal copper mesh.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises the two-layer oilpaper be oppositely arranged 1, on described oilpaper 1 outer side, be provided with cutting line 4, on oilpaper 1 medial surface, be coated with epoxy adhesive layer 2 in the regional extent of cutting line 4, in the middle of the epoxy adhesive layer 2 of two oilpaper 1, correspondence is provided with electric resistance of stainless silk layer 3, on horizontal corresponding cutting line 4 positions, is provided with the small resistor metal copper mesh 5 of contact resistance silk layer 4; Wherein, epoxy adhesive layer 2 is mixed by rubber modified epoxy resin, standard solid type epoxy resin, aerosil, grade chopped strand, dicyandiamide solidifying agent and 2-benzothiazolyl mercaptan promotor.
The aerosil high-speed stirring that the rubber modified epoxy resin that described epoxy adhesive layer 2 is 175-205 by the epoxy equivalent (weight) of 65 weight parts is heated to add after 70 ℃ 3 weight parts is uniformly dispersed it, the grade chopped strand that adds 5 weight parts stirs, adding epoxy equivalent (weight) is standard solid type epoxy resin 35 weight parts of 2500-3100 again, in 130 ℃ of lower stirring and dissolving, be cooled to 90 ± 2 ℃, add the dicyandiamide solidifying agent high-speed stirring of 6 weight parts, the 2-benzothiazolyl mercaptan promotor of adding 3 weight parts when temperature is down to 70 ± 2 ℃ makes; Described small resistor metal copper mesh 5 connects power supply.
During use, along cutting line 4, cut the glue-line of suitable size according to the size by maxxaedium, film is laid between two connecting surfaces of clearing up, on small resistor metal copper mesh 5, switch on power, regulating power source voltage is controlled current flow heats makes film solidify bonding with suitable speed intensification.The heat temperature raising of connecting with the mains on small resistor metal copper mesh 5 during dismounting makes the temperature of film meet or exceed its second-order transition temperature, at this temperature, the mechanical property of film is very low, and now two bonded faces being applied to a very little power just can be by two bonded separately.
