Definitions
- This invention concerns in general an antistatic flexible abrasive on a plastic film support used in the form of a tape.
- the invention refers to a flexible support made by using a combination of support material with a plastic film as its base.
- the invention also refers to flexible abrasives made by using combined materials on a plastic support, to the production method of this combined support and to an established application of this flexible abrasive which uses this support .
- the printed part of the plastic support can be treated with polymers or acids or electric systems (Corona system) or mechanical systems in order to increase the features of adhesion and mechanical friction.
- This invention can be applied in the field of abrasives and in particular in the sector of flexible abrasives in tape form.
- a flexible abrasive comprises a support element, a "maker coat” or also a layer of adhesive applied on the surface of the support, followed by the application of abrasive granules on the maker coat when it is still wet.
- the maker coat is the layer which, appropriately treated, allows the adhesion of the abrasive granules to the support.
- a second layer of adhesive known as a "size coat” is then usually applied on the maker coat and the adhesive layers are fully treated.
- the abrasive is then made flexible to break the rigid adhesive layers and produce a suitably flexible abrasive product.
- the flexible abrasive is subsequently transformed into various abrasive products such as sheets, discs, tapes, etc., according to the particular use of the flexible abrasive, the specific components of the abrasive, the product to be processed and the way in which it is carried out.
- the traditional support used in the production of the flexible abrasive can be made of various materials, depending on the application of the flexible abrasive, for example paper, fabric, plastic (polyester film) .
- the support can, for example, be a woven or "stitch-bonded" fabric such as rayon, cotton, nylon, polyester or mixed fabrics.
- This roughness in the use of the flexible abrasive converted to tape form is in proportion to the degree of friction necessary in the use of automatic and semiautomatic machines .
- This proportion is greater when the abrasive granule is a macrogranule .
- abrasive grains from P120 to P16.
- a first drawback is encountered with the use of conventional abrasives on plastic film in tape form.
- the abrasive support can not be used on automatic or semiautomatic machines in the form of narrow or wide tapes due to slipping.
- Another important problem is the dissipation of the heat generated by the friction of the tapes during polishing with automatic and/or semi-automatic machines. This problem is particularly evident in the finishing of glossy furniture with polyester and polyurethane-based paints .
- This invention proposes to provide a new support for the production of flexible abrasives, with improved yield and performance for the tape sanding of furniture, plastic materials, marble finishing, and sanding of resins and paints of ferrous and non-ferrous materials.
- the products created according to the invention concern a flexible abrasive for sanding applications, in the form of tapes that have greater resistance to clogging, better finishing, better resistance to tensile stress, better antistatic features, and better dissipation of heat with respect to the traditional abrasives used to date.
- the coated flexible abrasive consists of a layer of abrasive-containing resins, a support plastic film layer and a reinforcement substratum of paper, sponge, Velcro, fabric or other similar material which satisfies the following requirements: it is economical, resistance to tensile stress, can absorb shocks, dissipates heat easily, is extremely antistatic and has sufficient friction for use in automatic and semi-automatic machines.
- This type of flexible abrasive on a combined support according to the invention allows easier and practical handling and installation in automatic and semi-automatic machines .
- the resulting flexible abrasive has greater mechanical resistance to tensile stress, greater heat dissipation, less tendency to clog, greater shock- absorbance, better finishing, and greater antistatic ability than a product with just film or traditional abrasives (paper, fabric, combined paper-fabric , non- woven, etc . ) .
- the antistatic process (with the addition of graphite, mineral salts, and more in general of substances that allow ion exchange) is carried out at the same time as lamination of the support while, according to background art, in some specific applications an antistatic product is added to the resin with which the abrasive is bound or coated.
- Abrasive film do not generally have marked antistatic properties as they are mainly used in disc form (there is no way of accumulating high charges in this format due to its size) .
- the electrostatic charge that accumulates on the tape can sometimes reach high enough values to generate electric sparks .
- the antistatic properties of the polyester film can therefore be achieved as follows:
- figure 1 represents a schematic diagram of the production of the flexible abrasive on a combined support by means of lamination
- Figure 2 represents a cross-section of the flexible abrasive on a combined plastic film support and base support .
- Figure 3 represents a schematic diagram of the production of the flexible abrasive on a combined support according to the conventional method, that is to say starting from a laminated support;
- Figure 4 represents a schematic diagram of the production of the flexible abrasive on a combined support by means of lamination in line after preparation of abrasive according to the conventional method.
- figure 2 shows a cross-section of the flexible abrasive on a combined plastic film support and base support.
- the flexible abrasive on a combined support indicated overall with the reference number 10 comprises the combination, obtained in various ways, of a flexible abrasive on plastic film 11, comprising binding resins 8, with a base support or substratum 12 in Velcro and/or paper and/or fabric and/or sponge or other similar materials.
- the combined plastic film/substratum indicated with reference number 9 consists of the layered combination of the following materials: a layer of plastic film 13, a base support or substratum 12 in Velcro / paper / fabric / sponge / (other similar materials) , and a layer of adhesive material 18, such as glue or the like.
- the flexible abrasive on plastic film (11) consists of: a layer of plastic film 13, a first intermediate binder layer or Maker Coat 1 , a second binder layer or Size Coat 15 which holds the layer of abrasive grains 16, and finally a third binder layer 17.
- the flexible abrasive on plastic film 11 is combined with the base support or substratum 12 in Velcro / paper / fabric / sponge, the base or substratum 12 being fixed to the plastic film 13 by means of a layer of adhesive material 18, such as glue or the like.
- figure 1 shows an example of the creation of the flexible abrasive on a combined plastic film - substratum support by means of lamination.
- the plant that allows the aforesaid lamination process indicated overall with 19 comprises a reel 20 of flexible abrasive on plastic film 21 which is transferred to a lamination cylinder 22 positioned in contact with an additional lamination cylinder 23 which receives the sheet of support material 24 from a reel 25.
- a container 26 of glue 27 is positioned between the two cylinders.
- the preparation of the flexible abrasive with a combined plastic film support and paper/fabric/Velcro/sponge base support for abrasive tapes can be carried out by applying the maker coat, abrasive and size coat to a combined support consisting of plastic film and paper / fabric / sponge / Velcro / other materials, and this application can be achieved in a direct fashion in two different ways:
- Figure 3 shows a plant suitable for the creation of the flexible abrasive on a combined support (plastic film substratum) by on-line lamination before the preparation of the abrasive according to the traditional method.
- This system optimizes production costs thanks to the continuous lamination and production of the abrasive process on the plastic film side.
- the working cycle of the lamination unit 31 shown in figure 3 comprises the presence of a reel of plastic film 32 and a reel of support base material 33 of paper, fabric, Velcro or sponge. These materials are laminated with the glue by means of the lamination cylinders 34 and 35 and the combined plastic film - base material (substratum of paper, Velcro, fabric or sponge) support moves on to the abrasive process stage.
- the parts of the plant necessary for this process are listed below:
- the film passes through the printing area 36, where the combined support is printed on the support side with the distinctive features of the product being processed.
- the film passes through the first binder - Maker coat 37, where a binder, which can be an animal glue, a ureic glue, a phenolic glue, an epoxy glue or any type of resin or glue that can be used to create adhesion of the abrasive to the plastic support, is deposited on the combined support .
- a binder which can be an animal glue, a ureic glue, a phenolic glue, an epoxy glue or any type of resin or glue that can be used to create adhesion of the abrasive to the plastic support.
- the sector 38 ensures that the abrasive is deposited on the combined support on which the first binder is still wet.
- the first binder must not be completely dry or catalysed in order to allow the adhesion of the grains.
- the abrasive is intended in a broad sense since it can be aluminium oxide, silicon carbide, zirconium, ceramic, diamond, titanium carbides or oxides or a mixture of any of the former including any other type of material that can be used as an abrasive .
- the film passes through a first oven 39 which dries and cures the first binder, allowing the the abrasive grains to grip the combined support .
- the required temperature depends on the type of binder used and can vary from 40°C to 130°C.
- the time needed in the oven varies according to the type of grain and resin used, varying from a minimum of 1 minute to a maximum of 2 hours .
- the film now passes through the second binder - Size coat 40, where, once the first resin is dry, the product (consisting of the combined support, the first binder and the abrasive grains) is coated with a fixing binder or size coat, which in turn can be an animal glue, a ureic glue, or a phenolic glue, etc., depending on what the product will be used for.
- a fixing binder or size coat which in turn can be an animal glue, a ureic glue, or a phenolic glue, etc., depending on what the product will be used for.
- This binder is deposited on the product by means of rubber rollers, by air, spray or other systems.
- This resin coating can contain fillers such as calcium or potassium carbonate, iron oxides, dyes, stearates, and any other substance that can have a technical value for the use of the product or the economic property of the product .
- the product enters the second oven 41 for curing.
- the required temperature depends on the type of binder used and can vary from 40°C to 130°C.
- the time needed in the oven varies according to the type of grain and resin used, varying from a minimum of 1 minute to a maximum of 2 hours .
- the product is wound on the finished reel 42 and, depending on the binders used, can be used as it is or transferred to post-curing ovens for perfect catalyzing of the binders before the product is used.
- Figure 4 shows a plant suitable for the creation of the flexible abrasive on a combined support (plastic film - substratum) by on-line lamination after the preparation of the abrasive on plastic film according to the traditional method.
- This system optimizes production costs thanks to the continuous lamination and production of the abrasive process on the plastic film side.
- the cycle begins from a reel of plastic film 43 positioned on an unwinder at the start of the plant, from which the film passes through a printer 44 for printing on the support side with the distinctive features of the product being processed.
- a binder which can be an animal glue, a ureic glue, a phenolic glue, an epoxy glue or any type of resin or glue that can be used to create adhesion of the abrasive to the plastic support, is deposited on the combined support .
- the first binder must not be completely dry or catalysed in order to allow the adhesion of the grains.
- the abrasive is intended in a broad sense since it can be aluminium oxide, silicon carbide, zirconium, ceramic, diamond, titanium carbides or oxides or a mixture of any of the former including any other type of material that can be used as an abrasive.
- the film passes through a first oven 47 which dries and cures the first binder, allowing the the abrasive grains to grip the plastic film by means of the second binder - Size coat 48, and through the second oven 49 for curing .
- these materials are laminated in the lamination unit 50 by means of lamination cylinders using glue.
- the combined plastic film - base support (substratum of paper, Velcro, fabric or sponge) support is wound on a reel 51 and, if necessary, passed through a drying oven 52.
- the main components of the combined plastic film/paper abrasive that is to say the abrasive film and the paper/support) have antistatic properties .
- the glue used for the lamination also has antistatic properties. Therefore, according to the invention, carbon black, graphite, metal salts or similar are added to the binding resins (make coat and size coat) for plastic film abrasives.
- Paper type support carbon black, graphite, metal salts or similar are added to the paper pulp when the paper is produced, thus guaranteeing that the paper is antistatic .
- Fabric type support compounds able to form a reticulated polymeric structure around the filaments are used for fabric supports .
- an adhesive or glue with antistatic properties is use in the lamination step according to the invention.
- carbon black, graphite, metal salts or similar are added to the glue (whether it is vinyl, polyurethane or another type) to allow movement of the elecrtic charges.
- the abrasive tape according to t he invention is thus completely antistatic, achieving the predefined aims .
- Type of abrasive tapes Abrasive tape with combined support produced by laminating Abrasive Film and Paper, Abrasive Film and Velcro, Abrasive Film and Fabric
- the test was carried out using a Nerli semiautomatic machine. The objective was to evaluate the working conditions to discover why the abrasive tape with different supports stopped when the speed and pressure changed. The halt of the abrasive tape shows that the friction of the "abrasive film - piece being processed" is greater than the friction of the "support - movement pulleys" .
- the piece to be sanded (same size and type of paint) and the conditions (same machine speed and pressure) being the same, the grain of the tapes being the same, the finish of the pieces sanded with the abrasive on a laminated support is better.
- the constancy of the roughness obtained with the products on a laminated support is also markedly superior (approx. 1.7:1).
- the piece to be sanded (same size and type of paint) and the conditions (same machine speed and pressure) being the same, the grain of the tapes being the same, the life of the abrasive on a combined film support is much longer than that of traditional abrasives (abrasive currently used in the process) .
- the tapes produced with a laminated support have similar installation times to traditional abrasives, while those produced using only unsupported plastic film require a slightly higher handling time.
- the products used also have the marked antistatic features of traditional abrasives, but guarantee a markedly better finish and resistance to clogging.
- the antistatic property is extremely important in the wood and painting sectors, where the electrostatic charge that accumulates on the supports can generate sparks . In certain conditions, these sparks can cause the ignition of polishing dust and of suction systems.
- the flexible abrasive with combined support consists of a layer of abrasive- containing resins, a support plastic film layer associated with a reinforcement substratum of paper, sponge, Velcro, fabric or other similar material which satisfies the following requirements: it is economical, resistant to tensile stress, can absorb shocks, dissipates heat easily, is extremely antistatic and has sufficient friction for use in automatic and semiautomatic machines.
- the product obtained allows easier and practical handling and installation in automatic and semi-automatic sanding machines .
- the resulting flexible abrasive has greater mechanical resistance to tensile stress, greater heat dissipation, less tendency to clog, greater shock- absorbance, better finishing, and excellent antistatic properties compared to a product with just film or traditional abrasives (paper, fabric, combined paper- fabric, non-woven, etc.).
