This type of adhesive can be used to adhere fluorinated polymers, especially polyfluoroethylene difluoride (PVDH), to polymers that are incompatible with it. For example, polymer A can be derived from polymethyl methacrylate It can be obtained by reacting polymethyl methacrylate with ammonia or sleep amine. Other polymer A and its preparation method have been described in European Patent No. 216, 505. The third molecular part represents less than copolymer A 20% by weight * Preferably 1 to 6% by weight of copolymer A. According to the present invention, the fluorinated polymer that can be used with the binder has a homopolymer of vinylidene fluoride (VF2), three Homopolymer of vinyl fluoride (VF3), a combination of chlorotrifluoroethylene (CTFE), tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and (or) ethylene and optional VF2 and (or) VF3 molecular parts The resulting homopolymers, especially terpolymers.

Description of the invention (4) The contained polymers include mono-polyamides, copolymerized polyamides or poly-KΙΘΕ alloys or mixtures thereof. For example, the polymer may be polyamide (PA), PA -4,6, PA-6,6, ΡΑ-6, ΡΑ-δ, 12, PA-11, ΡΑ-12 and PA-12,12 or mixtures thereof. The polyamine alloy may be a polyamide matrix. Particles of another polymer are dispersed in it, as described in US Patent 4,174, 3 58 The polyamide may contain a modifier. The present invention also provides a mixture of polymer A and polymer M to reduce its elastic coefficient. In fact, the binder containing polymer A may be too hard in some applications; Mix it with another polymer to get K to make it less hard. The amount of this other polymer depends on the hardness. K can use an elastomer or a polymer modified with polymer A that is compatible with the polymer. Vinyl fluoride. The adhesive according to the present invention can be used as a co-extrusion adhesive. The present invention also has a material containing three layers • The three layers are in turn a layer of fluorinated polymer (such as polyvinylidene fluoride), A layer of the adhesive of the present invention and a layer of polymer that is incompatible with the fluorinated polymer. These calendars can be plates or films; they can be flat or round and simple. For example * they are tubes or small tubes. The polymer that is incompatible with the fluorinated polymer is preferably polyglycosamine, copolyglycosamine, or polyamide alloy. This three-calendar material can be made by common co-extrusion or replication chess-plastic technology. This three-layered material can be directly co-produced by, for example, first extruding the fluorinated polymer layer, and then repeatedly extruding or co-extrusing the adhesive Tau and Incompatible polymer history of fluorinated polymers. If the multi-calendar material contains additional layers, it still does not deviate from the scope of the present invention; for example, the fluorinated polymer can have a polyaminocarbamic acid_I --..---- 人- Installed ----- ^ I. 計 _------ ί line (please read the precautions on the back before filling in this page) This paper size is applicable to China National Standard (CNS) Α4 specification (210Χ297mm) 83 3. 10,000 The Ministry of Economic Affairs Central Sample Falcon Bureau Employee Consumer Cooperative Printing Bag 39? 834 A7 —_5Z__ V. Description of the invention (5) * That is, the order of each layer is poly »amine / adhesive surface based on polymer A / gasification polymerization Materials / adhesives / polyurethane. There may also be another adhesive on the fluorinated polymer layer (such as described in European Patent No. 450,994) after the poly (acrylic navel-butadiene-styrene) (ABS) layer, which is the order of each calendar It is polyacetamide / adhesive based on polymer A / fluorinated polymer / adhesive / ABS. The multilayer material may also contain several layers of the adhesive 1 of the present invention, that is, for example, the order of the layers is polyamine / adhesive based on polymer A / cyanide polymer / adhesive based on polymer A / poly Sugar amine. A particularly advantageous multi-layer material form of the present invention is a tube made of polyacetamide. Its internal calendar is made of fluorinated polymer (preferably polyfluoroethylene). Such a tube is used to supply fuel to In the car engine. For reasons of safety and environmental protection, automobile manufacturers require the following mechanical properties for fuel pipes: strength and flexibility, Μ and characteristics that increase the resistance to penetration. The tubes must have the lowest permeability for petroleum products and their additives (especially formazan). At present, polybromoamine tubes are commonly used in the automotive industry. Polyamide is an excellent material for this kind of tube application. Polyamide tube has excellent mechanical strength. Its flexibility is sufficient to allow the tube to withstand the accumulated bending during the service life of the vehicle assistant. • The action does not break. However, in terms of permeability, polyamide tubes no longer meet the new requirements of automobile manufacturers. It is suspected that the increase of formazan in gasoline has caused the expansion of the tube made of polyamide to show the phenomenon of swelling, resulting in a reduction in mechanical properties and deformation. In order to overcome this lack of viscosity and retain the mechanical properties of polyamide, according to this -8---Ί--Γ --- 1 1 ^-装 --------- 定 · ----- -First line (please read the precautions on the back and then fill out this page) The paper size is applicable to the Chinese national standard (CNS ί M specifications ί 0X297mm) 83. 3.10,000 Printed by the Employee Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs Pack A7 B7 V. Description of the invention (6) In the invention, the inner wall of the polyacetamide tube can be lined with a layer of fluorinated polymer, preferably polyfluoroethylene difluoride. If the auxiliary properties of fluorinated polymers (especially polyfluoroethylene difluoroethylene) are not particularly important, then the fluorinated polymers are preferably as thin as possible to retain the highest flexibility of polyamide. Because the outer diameter of the delivery pipe of the engine fuel gun based on the M polyetheramine is usually 6 to 12 g. • The thickness of the inner layer of fluorinated polymer (preferably polyvinylidene fluoride) * 1 is 10 microns to 1 Between male and female, and the thickness of polyglycosamine is between 0.8 and 1.8 grams, and there is a layer of adhesive between polyamide and fluorinated polymer with a thickness of 10 microns to 1 mm. It is important that the fluorinated polymer can be efficiently bound to the polyglycosamine. The tube that does not adhere between the fluorinated polymer and the polyamine cannot have good flexibility, so it cannot be folded or bent in thermoforming; in this case, the thinnest material is folded during operation . In addition, if the two layers are not adhered to each other *, possible gas condensation between the two mills may cause the thinnest part of the tube to deform over time. In addition to this, the pipes are connected to each other, and are connected to the fuel tank and the carburetor through the pipe coupling, the latter cannot be leak-proof when it is connected to the second separation layer. Finally, when the thickness of the fluorinated polymer in the tube is very thin, for example, from 10 to tens of microns, and there is no adhesion, the pressure difference of the tube irreversibly deforms the fluorinated polymer film, which makes the tube unusable use. It has been observed that the inner calendar of the fluorinated polymer is adhered to the outer polyamine tube via the adhesive of the present invention. Compared with the tube made of polyamine, the former reduces the permeability by 10 times * while retaining other properties ( (For example, cold balance impact strength) and within the limits of the automobile manufacturer's specifications.

If the polyamide layer contains or is mainly made of remanufactured tube materials, it has not yet deviated from the scope of the present invention, and will soon come from the grinding of polyamide tubes (especially the multiple calendar structures of the present invention). Crush and mix with polyacetamide if necessary. Some of the re-crushed material can also be used in the middle of the adhesive and polyacetamide. For fuel pipes, the bonding surface based on polymer A is more polymerized than gasification.

Invention description (8). The fuel pipe thus manufactured is particularly resistant to leaven, alcohol-containing fuel and heat. It has also been found that the mixture of polymer A and gasified polymer can be used as a binder, and at the same time can be used as a fuel blocking substance, especially fermented fuel. Therefore, the present invention also provides a fuel tube having a binder of between two layers of polyamidoamine. In this binder • the fluorinated polymer is preferably replaced by an elastomer-modified fluorinated polymer • or preferably the hydrocarbon matrix is added to the binder matrix (Polymer A and cyanide polymer) Fluorinated polymers modified by FFI and / or polymers compatible with Polymer A. The examples under K further illustrate the invention but do not limit the invention with M. In these examples, those polymers that are incompatible with the first polymer (the homopolymer of VF2) are polyacetamides. The polyvinylidene fluoride / adhesive / polyamide compound is used in the form of a tube, but it can also be made into a film, tank, or storage tank. These tubes K are co-extruded.
