A pure mica scale (the diameter is from 0.5 mm to 1.5 mm, and the thickness is 0.01 mm) is made into the film, wherein, the thickness of which is from 0.1 mm to 0.3 mm. Then, the definite amount of anticorrosion resin penetrates in the film and the film is baked; a piece of fiber cloth and a plastic film are coated on the surface of the film, and the film is made into a roll. The film is stuck to or is wound on the internal wall of a lined device in use. The utility model can be used in the internal wall of a chemical device, a large-sized storage tank, a glass fibre reinforced plastic pipeline and a storage tank and is novel material with most favorable anticorrosion and antipenetration effect currently.

Description

The mica flake film

The utility model relates to a kind of anticorrosion, impervious, wear-resisting mica flake film, mainly is applicable to the anticorrosion storage tank and the pipeline of chemical industry, oil, medicine, food, bridge, offshore platform, steamer, fiberglass.

According to statistics, corrosion loss has surpassed the loss summation such as natural calamities such as earthquake, floods, fire.Account for 4% of gross national product in world developed country.China is then up to 10%, and in recent years, the anticorrosion expert constantly studies new material for solving an anticorrosion difficult problem both at home and abroad, developed in succession with the scale of materials such as mica, glass, graphite, stainless steel, the zinc corrosion-proof paint as flake stuffing.Continue according to the experience valency in " 94 " of holding recently Sino-Japan anti-corrosion macromolecular material international exchange meeting, Fuji's scale resin of Japan was promoted the use of in the whole world so far since 1976, and effect is remarkable.Japan also is defined as the VE-GF lining part coated material of the TBL petroleum storage tanks that is used for national appointment and JR railway, bridge, contains glass flake 20-30 layer in the every 1mm coating of this material, scale content about 30%.Because the evenly distributed and irregular alignment of scale makes antiseptic power differ 30%, and the construction method of flake paint is mainly operated by manual at present, through brush, smear, operation such as spraying, on coating, carry out roll extrusion then, this obviously is difficult to guarantee the regularly arranged of coating layer thickness and scale, bubble in the coating can't be eliminated, so directly influence anticorrosion ability.

The purpose of this utility model provides a kind of mica flake film, is intended to improve and makes coating with materials such as glass flakes at present both at home and abroad, relies on manual operations to be difficult to guarantee the disadvantage of the regularly arranged and became uneven of scale.The utility model is to succeed in developing on the basis of burn into anticorrosion theory and practice and my many years of experience.Through calcination, physics and chemistry is handled or is pulverized with high pressure water impact with the mica muck in elder generation, and it is big to obtain radius-thickness ratio example difference, as sheet footpath 0.5-1.5mm, and the clean mica flake below the thickness 0.01mm.Be equipped with the mixed with it pulping of water in the groove of cylinder one, heating continuously then, and continuous rotary drum make the bright and clean surface of cylinder starch with mica flake and contact, and dip and obtain the film coil that thickness is 0.1-0.3mm.Select different resins for use according to the different chemical medium, as unsaturated polyester (UP), vinyl esters, phenolic aldehyde oxireme ester, epoxy resin, polyurethane, furfuryl alcohol furans or its mixture.The mica flake coiled material is soaked into the back oven dry in above-mentioned resin.Make the mica flake film article at multiple last layer glass cloth in its surface or plastic sheeting separation layer again, its specification is 0.1-0.3mm * 50-500mm, during construction, need only be clean with being handled by the lining equipment surface, coat resin then, dry when tack-free, again this mica flake film surface glass cloth or plastic sheeting are torn about 10cm, be affixed on the backing member surface, subsides are progressively torn glass cloth behind the jail, paste forward.Pasting level and thickness requires with the corrosion-resistant time limit of design and use unit and decides.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the profile of the utility model mica flake film.

As seen from the figure, mica flake film of the present utility model is made up of mica flake 1, resin 2 and separation layer 3.Mica flake 1 is parallel overlapping in resin 2, is maze-type structure.Not only corrosive medium (4) is constituted a lot of barrier, and make the infiltration palpus process of medium in lining not have several tortuous approach, thereby at the thickness that has objectively strengthened anticorrosive coat.This surfoyl is cut apart microbubble, micro-crack and the molecular level hole in the resin mutually, has suppressed the diffusion and the infiltration of medium more effectively.Being to contain scale 20-30 sheet in the film of 0.1mm as this material thickness, is 10 times of Japanese fuji resin, and scale content 70-80% is 3 times of Japanese fuji resin, and scale all can rule arrange equably, and anticorrosion impervious function is considerably beyond Japan.

The utility model fundamental difference is in domestic and international similar products.At present both at home and abroad similar products can only be made coating with scale, and construction method is only smeared, sprays, brushes, rolled etc., and the utility model can adopt mounting method, the construction of methods such as winding method, simple to operate, thickness is even, stop the infiltration of medium effectively, improved construction quality.

The utility model reduces the lining coefficient of thermal expansion, prevents that stress from peeling off.Mica flake has disperseed stress, and the residual stress of each contact-making surface is little, and thermal coefficient of expansion is little, so adhesive strength can be because of heat expansion decay, and Heat stability is good.

The utility model wearability and stronger to abrasive repellence.Meet mechanical damage and be only limited to the part, only need to do simple process, repair easily at the destruction place.

The utility model is compared with anti-corrosion materials such as glass flake, fiberglass, lining rubber also has the low advantage of cost.

The utility model is through the test of many times application, and its best way is to make the lining of various large-scale storage tanks, pastes this product 4-8 layer in reservoir walls and can play anticorrosion, antiseepage, effect such as wear-resisting; Replace anti-corrosion Fuji resin with this product, shortly cut felt enhancement layer GRP pipe, wall within the storage tank only needs can improve around the 4-6 layer at inwall that glass fiber reinforced plastics product is withstand voltage, impervious, anti-wear performance.It is reported GRP pipe, storage tank is the highest can only compressive resistance 16kg/cm ², adopt the utility model only to need liner 4-8 layer to get final product compression resistance 60kg/cm ²And non-leakage, fundamentally solved the critical defect of GRP pipe and goods thereof.The utility model also can be used as anticorrosion, impervious, the high-abrasive material of desulfurizers such as offshore production platform and conveyance conduit, oil refining, coking, thermal power generation in addition, and development prospect is very wide.
