A kind of carpet protection polyethylene protective film
Technical field
The utility model relates to a kind of polyethylene protective film, and more particularly, the utility model relates to a kind of carpet protection polyethylene protective film.
Background technology
Car carpeting, residential carpet and various special-purpose carpet need to use polyethylene (PE) protective membrane that its surface is protected in manufacturing, transportation, secondary processing, storage and use, to avoid it to be polluted and to damage.At present, known PE protective membrane rolls into tape roll by base membrane layer and pressure-sensitive adhesive layer.Because the special construction of carpet surface; the contact area of it and PE protective membrane pressure-sensitive adhesive layer is very little; for making the PE protective membrane be fitted in carpet surface securely; usually require the PE protective membrane to have very high viscosity; but uncoiling power was very high when this also caused the PE protective membrane to use; time-consuming, and noise height during uncoiling, have a strong impact on Working environment.Because PE property of thin film softness, uncoiling power is easy to tensile deformation when high, so the carpet protection must more just can avoid this problem with the basement membrane thickness of PE protective membrane, so basement membrane thickness is generally greater than 60 μ m.And basement membrane thickness is big, pressure-sensitive adhesive layer thickness also want could guarantee greatly the PE protective membrane be attached on the carpet do not upspring, alice not, so pressure-sensitive adhesive layer thickness is generally greater than 20 μ m.Therefore, present known carpet protection uses PE protective membrane total thickness generally greater than 80 μ m, product cost height.
The utility model content
The purpose of this utility model is to provide a kind of new carpet protection polyethylene protective film, and this carpet is protected with polyethylene protective film has advantages such as cost is low, noise is low when being easy to uncoiling and uncoiling, can overcome the deficiencies in the prior art.
The purpose of this utility model is achieved through the following technical solutions:
Polyethylene protective film is used in a kind of carpet protection, comprises base membrane layer, adherent layer and pressure-sensitive adhesive layer.Wherein, described adherent layer is coated on the surface of base membrane layer; Described pressure-sensitive adhesive layer is coated on another surface of base membrane layer.
Described base membrane layer is prepared from by polyethylene film, and its thickness is 30 μ m~35 μ m, need carry out corona treatment earlier before coating adherent layer and pressure-sensitive adhesive layer.
Described adherent layer is a solidified ultraviolet light polymerization adherent layer at room temperature, and its thickness is 0.3 μ m~2 μ m.
Described pressure-sensitive adhesive layer is prepared from by polyacrylate pressure-sensitive or rubber pressure-sensitive adhesive, and its thickness is 10 μ m~15 μ m.
In the utility model, described adherent layer is the adherent layer of ultraviolet light polymerization, contains multiple functional groups such as carboxyl, hydroxyl and glycidyl, has good sticking power with the base membrane layer that passes through corona treatment.Because the existence of this adherent layer; make that the uncoiling power of polyethylene protective film is very low; noise is low and be difficult for tensile deformation during uncoiling, therefore can reduce the thickness of described base membrane layer and pressure-sensitive adhesive layer greatly, thereby reduces the carpet protection greatly with the total thickness of polyethylene protective film and the cost of product.
Description of drawings
Fig. 1 is the sectional view of carpet protection described in the utility model with polyethylene protective film.
Embodiment
As shown in Figure 1, carpet protection described in the utility model is made up of base membrane layer 1, adherent layer 2 and pressure-sensitive adhesive layer 3 with polyethylene protective film.Wherein, base membrane layer 1 is that the polyethylene film of 32 μ m is prepared from by thickness; Adherent layer 2 adopts the adherent layer of ultraviolet light polymerization; And pressure-sensitive adhesive layer 3 is prepared from by polyacrylate pressure-sensitive.
After base membrane layer 1 carried out corona treatment, adherent layer 2 is uniformly coated on the surface of base membrane layer 1, the thickness of adherent layer 2 is about 1 μ m.Behind the coating adherent layer 2, once more base membrane layer 1 is carried out corona treatment, then pressure-sensitive adhesive layer 3 is uniformly coated on another surface of base membrane layer 1, the thickness of pressure-sensitive adhesive layer 3 is about 12 μ m.At last, the gained finished product is rolled into tape roll.
