Abstract
The invention discloses a single-sided low-viscosity PVC (polyvinyl chloride) protective film. The protective film comprises a substrate layer and an adhesive layer, wherein one surface of the substrate layer is directly covered by the adhesive layer uniformly in parallel; the substrate layer is a PVC film layer; and the adhesive layer is an acrylic acid pressure sensitive adhesive layer. The protective film has the beneficial effects that the protective film ensures various performances of the products while simplifying the product structures, enables the products to have excellent flame retardance, corrosion resistance, temperature resistance, waterproofness and other performances, reduces the product thickness, has excellent transparency and low viscosity, is easy to fit and strip, is free from adhesive residues and traces after stripping, lowers the production cost and prolongs the service life.
Description
Technical field
The present invention relates to the protective film of electronic product field, particularly relate to the low sticking protective membrane of a kind of PVC single face.
Background technology
Protective membrane is the substrate surface that is attached at some electronic products, makes it in carrying, storage, processing and use procedure, avoids being polluted or scratching.Normally used protective membrane has PVC protective membrane and PET protective membrane; because PET protective membrane hardness is higher; model keeping character is good; not flexible; easy scratch adhesion surface during adhesion; and easily warp, impact attaches effect and visual appearance, generally all adopts the PVC protective membrane at the special-shaped substrate surface of having relatively high expectations.
Existing PVC protective membrane texture is soft; it is convenient to paste; generally first apply the release oil of one deck at the PVC substrate surface; the pressure sensitive adhesive of fitting again; and what pressure sensitive adhesive adopted is rubber pressure-sensitive adhesive; this just makes the PVC protective membrane thickness of this material thicker, and transparence is bad, makes wall-attached surface seem dimmer.Also can stay the marking of glue after tearing on wall-attached surface.This material is also yellow fuel-displaced than being easier to turn over along with the change of temperature simultaneously, and work-ing life is shorter.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art; provide a kind of PVC single face low sticking protective membrane; have good fire-retardant, corrosion-resistant, heatproof, the performance such as water-fast; and reduced product thickness, transparency is good, and viscosity is low; easily fit and peel off; peel off without cull, without vestige, and reduced production cost, increased work-ing life.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: provide a kind of PVC single face low sticking protective membrane; the low sticking protective membrane of described PVC single face is comprised of substrate layer and adhesive-layer; one side surface of described substrate layer is directly parallel evenly is covered with described adhesive-layer; and described substrate layer is the PVC thin film layer, and described adhesive-layer is the acrylic acid or the like pressure-sensitive adhesive layer.
In a preferred embodiment of the present invention, the viscosity of described adhesive-layer is 20-100 g/25.4mm.
In a preferred embodiment of the present invention, the thickness of the low sticking protective membrane of described PVC single face is 0.05-0.1mm.
In a preferred embodiment of the present invention, the thickness of described adhesive-layer is 0.02-0.03mm.
The invention has the beneficial effects as follows: cover one deck adhesive-layer by Direct Uniform on a surface of substrate layer, need not to smear release oil, when simplifying product structure, guaranteed the properties of product, make it have good fire-retardant, corrosion-resistant, heatproof, the performance such as water-fast, and reduced product thickness, transparency is good, and viscosity is low, easily fit and peel off, peel off without cull, without vestige, and reduced production cost, increased work-ing life.
Description of drawings
Fig. 1 is the structural representation of low sticking protective membrane one preferred embodiment of PVC single face of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, substrate layer, 2, adhesive-layer.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also shown in Figure 1ly, the embodiment of the present invention comprises:
the low sticking protective membrane of a kind of PVC single face, the low sticking protective membrane of described PVC single face is comprised of substrate layer 1 and adhesive-layer 2, one side surface of described substrate layer 1 is directly parallel evenly is covered with described adhesive-layer 2, and described substrate layer 1 is the PVC thin film layer, a kind of universal synthetic resins, transparency is high, glossy, matter is soft, good toughness, have fire-retardant (fire-retardant value is more than 40), high (the anti-concentrated hydrochloric acid of chemical proofing, concentration is 90% sulfuric acid, concentration is 60% nitric acid and the sodium hydroxide of concentration 20%), water-fast, heatproof (can be anti-80 ℃), the advantage that physical strength and electrical insulating property etc. are good, described adhesive-layer 2 is the acrylic acid or the like pressure-sensitive adhesive layer, has low temperature resistantly, high temperature resistant preferably, can coagulate volatile matter and mass loss rate is low, and the characteristic of overflowing without obnoxious flavour, all kinds of Pressuresensitive Tapes of making, convenient stickup to film.
Wherein, the viscosity of described adhesive-layer 2 is 20-100 g/25.4mm, hangs down viscosity, easily fits and peel off, and peels off without cull, without vestige.
The thickness of the low sticking protective membrane of described PVC single face is 0.05-0.1mm, by reducing the thickness of product, transparence is increased.
The thickness of described adhesive-layer is 0.02-0.03mm.
The low sticking protective membrane of PVC single face of the present invention is applicable to the surface protection of automobile collision preventing bar, safety lever, special-shaped aluminium alloy and stainless steel plate etc., is attached at panel after 80 ℃ * 1h temperature, peels off without cull, without vestige.
The present invention has disclosed the low sticking protective membrane of a kind of PVC single face, covers one deck adhesive-layer by Direct Uniform on a surface of substrate layer, need not to smear release oil; when simplifying product structure; guaranteed the properties of product, made it have good fire-retardant, corrosion-resistant, heatproof, the performance such as water-fast, and reduced product thickness; transparency is good; viscosity is low, easily fits and peels off, and peels off without cull, without vestige; and reduced production cost, increased work-ing life.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
