Description
Technical field
The present invention relates to adhesive tape production technique field, more particularly to a kind of production technology of foam adhesive tape.
Background technology
Foam adhesive tape is produced using automation coating technique mostly, is mostly from PU, PE, TPV, XPE, ternary second
Thirdth, the foam such as rubber and plastic, Nomex, hot melt felt is base material, is respectively coated various high-quality adhesive stickers and is equipped with various high-quality auxiliary materials,
Through special process be composited it is soft, adiabatic, insulation, sealing adhesive tape；Adhesive tape is divided into two kinds of material classes of closed pore and perforate
Type；It is widely used in automobile, the air conditioner refrigerating of ship, upholstery；Air conditioning for automobiles, the air duct joint of civil air conditioner, air door etc.；
The cement joint of urban architecture, the sealing of door and window is heat-insulated etc.；With firm pasting, using it is efficient and convenient the characteristics of, be a kind of tool
Have sound insulation, it is heat-insulated, glow, waterproof (closed pore), damping, sealing, environmental protection, the product of the premium properties such as sound-absorbing.
But existing foam adhesive tape band resilience is relatively poor, and elongation is not high, and intensity is also inadequate, the ageing-resistant time
It is short and be mostly made of material using not environmentally.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of production technology of foam adhesive tape, the method process is simple,
The foam adhesive tape for preparing, preferably, elongation is high, and intensity is high, and the ageing-resistant time is long and imparts fire-retardant work(for resilience
Can, have a good application prospect.
The technical solution adopted for the present invention to solve the technical problems is：A kind of production technology of foam adhesive tape is provided, is wrapped
Include following steps：
A () is coated with one-component polyurethane water as tack coat on EVA film surface；
B () sequentially adds the fire retardant of 5-10%, the viscosity modifier of 3-4% and 4-7%'s in polyaminoester emulsion
Antiager, forms polyurethane mixed liquor；
C polyurethane mixed liquor foaming is formed foamed cotton layer by () at 110-130 DEG C on tack coat；
D () covers layer protecting film on foamed cotton layer, obtain final product foam adhesive tape.
Further, the fire retardant in step (b) is APP.
Further, the viscosity modifier in step (b) is Petropols system viscosity modifier.
Further, the antiager in step (b) is resistance to old by Hinered phenols antiager and phosphorous acid esters
Agent compounding forms (mass ratio 2:1).
Further, using foaming of getting blisters preceding is first passed around, frostproof froth n rate is or not the polyurethane mixed liquor in step (c)
Less than 100%.
Beneficial effect
Present invention process is simple, the foam adhesive tape for preparing, and preferably, elongation is high, and intensity is high, when ageing-resistant for resilience
Between it is long and impart fire-retardant function, have a good application prospect.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.

(b) sequentially added in polyaminoester emulsion 5% APP, 3% Petropols system viscosity modifier and
4% antiager (mass ratio 2:1 Hinered phenols antiager and phosphorous acid esters antiager compounding are formed), form poly- ammonia
Ester mixed liquor；
C the polyurethane mixed liquor (is first passed around foaming of getting blisters, frostproof froth n rate is not less than by () at 110 DEG C
100%) foaming forms foamed cotton layer on tack coat；
D () covers layer protecting film on foamed cotton layer, obtain final product foam adhesive tape.
Embodiment 2
A () is coated with one-component polyurethane water as tack coat on EVA film surface；
(b) sequentially added in polyaminoester emulsion 10% APP, 4% Petropols system viscosity modifier and
7% antiager (mass ratio 2:1 Hinered phenols antiager and phosphorous acid esters antiager compounding are formed), form polyurethane
Mixed liquor；
C the polyurethane mixed liquor (is first passed around foaming of getting blisters, frostproof froth n rate is not less than by () at 130 DEG C
100%) foaming forms foamed cotton layer on tack coat；
D () covers layer protecting film on foamed cotton layer, obtain final product foam adhesive tape.
Present invention process is simple, the foam adhesive tape for preparing, and preferably, elongation is high, and intensity is high, when ageing-resistant for resilience
Between it is long and impart fire-retardant function, have a good application prospect.
