Plastic edge band, method of its manufacture and its use

Kantband av plast, förfarande för dess framställning och användning

The present invention relates to a plastic embossed or embossed edge band containing pigments and / or fillers, a process for its manufacture and / or its use. According to the invention, this edge band consists of at least two layers of non-paper plastic sheeting or at least two layers of endless non-paper sheet material having a thickness of 400-4000 μπι and cut into 12-200 mm strips, the edge band comprising at least two extrusion, multiple extrusion or lamination, the composition of these individual layers being very specific.

Polyolefin-based furniture films are known from EP 213441. Unfortunately, if these films are used as edge strips, they do not meet the requirements. The adhesion to the edges is not good, the film is too brittle at the edges and easily damaged by impact, pressure and the like; trotters. Water and other factors easily lead to the gradual removal of the rim.

Rolled edge strips of paper and plastic for finishing furniture edges and surfaces of all kinds of boards are already known from GM 75 26 366. These edge strips. . The slides are made into strips of about 1 to 3 cm in width, 0.2 to 1 mm thick, made of paper impregnated with a synthetic resin (melamine resin, alkyd resin, polyurethane-urea-formaldehyde resin, or crosslinking acrylate resin). These paper resin impregnated strips of synthetic resin have the disadvantage that they are not mechanically strong and that they are easily damaged. In addition, these moldable edge strips should be improved in wood and wood-based materials for better adhesion and poor adhesion under humid conditions.

The object and purpose of the present invention was to avoid these disadvantages and to provide an improved edge band. In particular, the mechanical strength of this edge band should be improved and its adhesion should be improved due to the adhesive used, even when exposed to moisture later. If desired, the printing of this edge band should be effortless or embossed.

According to the invention, it has been found that these objects are attained and the task accomplished is solved by a plastic embossed or printed patterned pigment and / or filler-containing edge band which is a polyolefin film or a polyolefin-containing layer or film containing propylene or High Density Ethylene (HDPE), comprising at least one adhesive film immediately below or above it or through one or more interlayer (s).

This self-adhesive, solvent-free, simultaneously extruded adhesive film is located on the underside of an edge band containing a polar group, water-insoluble or water-insoluble plastic, copolymer, terpol ·. or a graft polymer or an alloy or a mixture thereof, or 3 105901 consists of these. The edge band according to the invention consists of at least two-ply paperless plastic sheeting or at least two-ply paperless endless sheet having a thickness of 400-4000 µm and is cut into strips 12-200 mm wide.

The plastic edge band of the invention is inserted without stretching it, so no stretching or stretching measures are required and are not even desirable within the scope of the present invention.

The edge band according to the invention is highly resistant to moisture and even water vapor. In addition, it is mechanically very strong and relatively resistant to stress or mechanical stress. The unstretched edge band can be easily provided with printing patterns and / or embossing patterns, and no special additional adhesive agents are required for insertion.

According to a preferred embodiment, 0.1 to 20% by weight, preferably 1 to 10% by weight, of the polar filler or filler mixture is replaced by the same weight of the polar filler or polar filler mixture, preferably uncoated kaolin and / or silica gel. Depending on the polar filler used in this manner, higher surface stresses can be achieved.

The mineral filler has as its polar substance or polar substances at least one organic-chemical compound having at least one OH group and / or COOH group and / or SiO or SiOR groups or other similar polysiloxane groups and at least one or more non-polysiloxane groups. polar group, and / or the filler is completely or partially coated with such a compound, which is a thin layer, whereby preferably the polar groups are oriented towards the filler or have reacted completely or partially with the filler.

It is important that the compounds comprising these polar and non-polar groups are not added separately in the making of the film, but that they are added together with the filler or filler mixture, whereby they should or should be located on the filler surface or part of the filler surface. If these compounds containing polar and non-polar groups are added separately during film production so that they are not on the surface of the filler, there is a risk of developing processing problems or the formation of degraded films.

According to another embodiment, the bead may further comprise one or more organic modifiers. These substances serve to control toughness, calendability, extrudability and other similar properties. A preferred group suitable for this purpose are styrene block polymers with butadiene or isobutylene or isoprene. Other suitable plasticizers are styrene-butadiene-based and methacrylate-butadiene-styrene-based polymers. Polyolefins containing functional groups can particularly influence the relationship between physical properties and adhesion. Such modifying additives are conveniently present in an amount ranging from 0.5 to 20 parts by weight, preferably from 2 to 10 parts by weight.

> · 105901

As mentioned above, the advantages of the film or edge strip according to the invention are better achieved when they have undergone surface adhesive treatment. This surface treatment preferably comprises activation by irradiation. Of the irradiation methods, however, corona treatment is preferred. However, other irradiation methods may be used.

Examples of other suitable irradiation methods include electron irradiation, UV irradiation and / or laser irradiation. Suitable devices for this purpose are also known.

According to a preferred embodiment, an interlayer or interlayer (12 ') containing a homogenous or mixed copolymer of propylene (in which the proportion of comonomer is less than 15% by weight) and HDPE or LLDPE as a binder is placed above a second polyolefin layer or film (13) containing or consisting of polypropylene and / or polyethylene, preferably HDPE, as a plastics material and containing from 0.5 to 55% by weight, preferably from 3 to 35% by weight of organic filler, or a filler blend, preferably cellulose having an average particle size of 5-100 μιη, preferably 7-50 μπι, with a maximum average length of up to 250 μτη, preferably up to 200 μπι, and / or starch (based on the total amount of polyolefin and organic filler); optionally, or consisting of processing aids, color pigments, dyes and / or modifiers.

According to one embodiment, the amount of cellulose is from 3 to 50% by weight based on the total amount of polyolefin and cellulose. If the concentration is greater than 50%, the strength properties are dramatically reduced.

s 105901

Conveniently, the cellulose present in the band of the invention has a fineness of 1-100 μτη, with a fiber thickness of 10-30 μτη. Obtaining a finer degree of distribution is too difficult, and with the use of larger particles one encounters difficulties when it comes to producing smoother and thinner films. However, in the case of natural and regenerated cellulose, particles up to 100 μτη with a maximum average length of 200 μτη can also be used, without encountering fundamental difficulties in forming films. Starches which are known per se, preferably potato starch and / or corn starch, may be used.

According to another embodiment, the bead may further comprise mineral fillers. Such fillers for polymeric films are known. Particularly suitable and therefore preferred are mica, talc, silicates and silicas in various forms. Examples of other useful mineral fillers include carbonates, especially calcium carbonates such as limestone and chalk, and magnesium carbonates and the like.

For example, properties such as Vicat score, Shore hardness, and tensile strength may be affected by the addition of suitable mineral fillers. If such mineral fillers are present, then the film conveniently contains from 3 to 50% by weight, preferably from 3 to 30% by weight, based on the total amount of polyolefin and cellulose.

; In addition, the bead may further comprise one or more organic modifiers. These substances serve to control toughness, calendering, extrudability and other such properties. A preferred group for this purpose are block polymers between styrene and elastomers such as butadiene or isobutene or isoprene. Other suitable modifiers include styrene-105901 butadiene-based and methacrylate-butadiene-styrene based copolymers. Polyolefins containing functional groups, for example copolymers, terpolymers or oxa-copolymers derived from ethylene and reactive monomers, can be particularly effective in influencing specific physical properties and adhesiveness. Such modifying additives are conveniently present in an amount of from 0.5 to 20% by weight, preferably from 2 to 10% by weight, each based on the total amount of polyolefin and cellulose.

In a generally preferred embodiment, surface activation is effected by irradiation or treatment with a flame or ozone. Corona treatment and other irradiation methods using electron beam, UV or laser radiation are particularly preferred.

As mentioned above, the invention improves substantially the adhesion of the polyethylene-containing edge strips to the surface, which results in a substantially improved or even improved use of such films in laminating, printing, painting and gluing, especially with modern equipment with short process times and maximum temperatures. possible. When the film or edge band of the invention was glued, its adhesion had not changed at all even after months. Likewise, the strength of the surface against the effects of temperature is greatly improved as a result of surface activation.

Printing inks, for example inks which are basic; adhesion to vinyl chloride-vinyl acetate-maleic acid terpolymers and OH-containing vinyl polymers, as well as conventional PE printing inks have the same adhesive properties as reaction coatings such as polyurethane and melamine adhesion. No variation in varnish adhesion was observed after ASTM Standard D 2141-63T, even after the 1000 hour Climate Impact Test and the Tropical Trial.

The properties of the edge band can be varied over a wide range by the addition of mineral fillers and / or organic modifiers without, however, diminishing the advantageous adhesive properties of the band. For example, the surface adhesion obtained by corona treatment of an edge strip comprising a layer of 95 parts polyethylene and 5 parts cellulose does not change even when 20 or 30 parts of talc are added to the tape. Other dyes or pigments also have no adverse effects.
